3.71 M33 Install Guide

[x3sphere]

Here is a step by step guide for installing 3.71 M33. Please note that you must be running 3.52 M33-3, 3.52 M33-4 or 3.60 M33 to begin this installation.

Note: Before installing 3.71 M33, be warned that it currently is lacking the 1.50 kernel, even on regular (Phat) PSPs. Dark_AleX does plan to release a 1.50 kernel patch within the next few days, but for now you can use the eLoader (http://forums.exophase.com/showthread.php?t=3540) to run 1.50 kernel homebrew on 3.71 M33.

Installation Guide

First grab the 3.71 M33 files (http://exophase.com/files/psp/release.rar) and extract them.

1. Copy the UPDATE folder contained in the archive to X:/PSP/GAME

2. Download the 3.71 EBOOT (http://exophase.com/files/psp/371.PBP), and then place it in X:/PSP/GAME/UPDATE

3. Navigate to the Game menu on the PSP and execute the program, it will not run unless there is 78 percent battery free.

4. Press X and the update process will start. Yes it may look similar to a regular Sony update but don't worry!

5. Once finished, the updater will ask you to press X or O to reboot. You MUST do this, otherwise you'll end up with a brick.

6. You've now successfully installed 3.71 M33 :)

There ya go, waitin' for this one, too many peeps askin' questions in the news thread.:p Nice stuff, as always, x3.

[Chilly Willy]

One note - because this custom firmware updater runs the actual 3.71 updater, your keys must be good before doing so. The cfw updater will unpatch key 5, but all other keys must be good or the 3.71 updater will quit without updating. This means that people running on a phat PSP should check their keys beforehand. You'll find my latest KeyCleaner here in the PspDevelopment forum.

All the keys reported by KC should be good, with 0x42 and 0x46 being clear, and key 5 being patched. The type of patch for key 5 doesn't matter, so long as it's just a patched key 5. If this is not the case, fix the keys before trying to update.

[Acerthief]

damn, that's not good. i tried your method your said in KC, going to 2.71 and unpatch key5, when i pressed the update EBOOT it stills asks me to go find a official techition.

[shadowthor]

Do you only need to unpatch key 5? Then you don't need to go through that method. Just update to 3.52 M33-4 (provided its only key 5 that was patch and the rest weren't corrupted) then update to 3.71 m33. When i updated to 3.71 m33 it unpatched the key and was like installing a normal firmware.

So... do i just follow the installation guide as it is or is this guide meant for 1.50FW only? I'm a total n00b here... thx for any help.

You have to have 3.60M33 installed before you install this, which I can only assume you don't. If you're running Sony 3.71 there is no way to do it at this point, you'll have to wait a bit, there'll be a release to downgrade PSPSL's soon.

[foesum_twinz]

thanks for help i have been trying to figure out this.

Im trying to go from 3.52-4 and after it says "starting SCE updater" my mem stick flashes around a bit like usual and then it stops and gives me the error:
The system cannot be updated.
The update data is not applicable for this

(CTA80000025)

Anyone know whats up?
BTW, its an old phat TA-082 and checked with Chilly Willy's key cleaner and patched key 5 only to get error above. Thanks

[Clyde18]

erm... I've never done any firmware upgrades myself (my 3.40-OEA was done by somebody else)
i'm running 3.40-OEA now, so... i just follow the guide as it is? Or do i need to downgrade to 1.50 first before proceeding with the guide?

Thanks a bunch.

[Clyde18]

i've read the readme.txt for this 3.71, and found out the requirements is at least 3.52 M33-3? So, that means i have to upgrade to 3.52 M33-3 first b4 i can move on to this 3.71 ?

If only key 5 is patched, it should work fine. That being said... this could be a problem with the idstorage beyond what KeyCleaner can fix.

You know if the PSP was hardware downgraded, or did you downgrade it yourself?

[shadowthor]

you can't get custom firmware because you are on Sony Official FW (3.7) and a downgrader has not been issued for the psp lite. But if you have the psp phat then you can use pandora to downgrade then upgrade to 3.52 m33-4 then to 3.71 m33. And piracy is not tolerated here.

Strange. Well the error you are getting appears to be due to a damaged idstorage or possibly bad blocks on the nand flash. You could try reinstalling 3.52 M33 and then upgrading back to 3.52 M33-4 to see if that fixes it. Don't really know what else to suggest.

Well right now, you're stuck on a non-homebrew enabled firmware, so the only way is to first downgrade your PSP using Pandora's Battery. There's a guide detailing how to do that here (http://forums.exophase.com/showthread.php?t=3238), however converting the battery requires a homebrew enabled PSP, so you'll need to know someone who has one.

If you don't know anyone who has a homebrew enabled PSP, then it is possible to buy an already converted battery. Might want to take a look at SonicTH's post if you decide to go this route:

i'm having a bit of a problem, at first i tried to update, except it told me that my firmware needs to be higher than 3.52-3, and then I checked and found out I only installed 3.52, and never the -3 or -4 updates. So then I followed the instructions on updating it to -4, and verified it in the system settings.

so then i tried again, but it's still giving me the same error. i've checked and all my keys are okay with 100% battery :X

To fix this, go into recovery mode (hold R during boot) and enter Configuration and set the GAME folder kernel mode to 3.52.

[Chilly Willy]

phat psp = older version psp.

A lot of people have objected to calling the older PSP "fat" simply because the new one is called "Slim and Lite", so people started calling it "phat" instead. It's pronounced the same, but phat is actually P.H.A.T., an acronym that stands for Pretty Hot And Temping. It was common slang used several years ago in the US.

thanks, that simple solution worked perfectly and now i'm running the 3.71 ^^

one note though, after installing it, verified that it was 3.71, and then headed over to theme and i got an error(that i forgot to take note of) and it basically gave me the corrupted screen and restored everything to 3.71 defaults :X

*edit*

after that happened, i turned off my psp, and held down R to go into recovery and i noticed i couldn't move to select anything... and then i bricked ^^;; now i'm gonna have to wait for my friend to come over so i can convert my battery for pandora :X

unbricked and i decided to stay on 3.52-4 a bit longer ^^;;

Hmm, strange. I did try the custom themes option on my PSP Slim and no problems here.

But I will tell D_A about this, could be a bug in the firmware, as someone else had a similar problem.

I just did my PSP and it came off without a hitch. The guide isn't Noob proof if you aquired the official firmware direct from the company rather than the guide, but I was keen enough to rename the official eboot firmware (I'm a PSP Noob but moreso savvy elsewhere on the PC). Thumbs up to everyone that made this possible.... again!

Edit: I almost forgot to mention. I ran the KeyCleaner and it said all was fine and that key 5 had the legit Chilly Willy patch. The new updater for 3.71M33 then told me that there were problems with my keys and offered to fix them. I did that, and the patch was successful. I then ran KeyCleaner and was told that all my keys were fine and that key 5 was not patched. Does this mean my IDString also was changed or is that a different item than keys?

Yep, key 5 is unpatched when updating since it is not needed to be patched anymore on 3.71 M33.

No question is stupid, unless it's a stupid question. This one isn't:p In 3.71M33 you can't use 1.5 compatible homebrew yet without the help of the 'eloader'. The patch will fix this.

Check out the guide for installing 3.60 M33. Yes, you will need to create a Pandora battery (use a regular battery only NOT the Slim battery) and magic memory stick to install 3.60 M33.

Creating the battery and installing the memory stick files requires a homebrew-capable PSP.

Corrupt memory stick is the most probable cause. Try formatting your memory stick and then copy the files back over.

First make sure the 371.PBP was fully downloaded, it should be around 22.5MB.

Secondly make sure it is in the correct folder X:/PSP/GAME/UPDATE

Also try formatting the memory stick (backup all files before doing this) and then copy all the files back and try running the updater.

Hey guys,

Just wondering, why does the new 3.71m33-2 release not contain the unmodule.prx file as in the previous 3.71m33 UPDATE folder?

Is this a problem and do we really need it when flashing to 3.71m33-2 from 3.60m33 on a Slim?

I'm trying my best to avoid a brick and want everything to be set correctly.

Also how long does the update take from the time you run it on the PSP to the time you have to press X to reboot?

Cheers in advance.

Is this a problem and do we really need it when flashing to 3.71m33-2 from 3.60m33 on a Slim?

I'm trying my best to avoid a brick and want everything to be set correctly.

Also how long does the update take from the time you run it on the PSP to the time you have to press X to reboot?

Cheers in advance.

Because the 3.71 M33-2 is just a small update for 3.71 M33, its not a whole new firmware update. Takes like 5 seconds to install.

Oh okay, so am I correct in thinking, I cannot go directly from 3.60m33 to 3.71m33-2?
Do I just have to install 3.71m33-1 first and then do 3.71m33-2?

With the full update, how long does it take to flash normally?

Yes that's correct. Takes around 5 minutes to install 3.71 M33-1, same as an official Sony update.

Sorry to be a ball breaker x3, you've been very helpful and quick to respond.

When I'm on 3.71m33-1, do I leave the unmodule.prx file in the update directory when I flash to 3.71m33-2 or doesn't this matter either way?

Doesn't matter either way, as the 3.71 M33-2 update does not attempt to load this file.

Hey all, I just updated to 3.71 and added 1.50 correctly. Everything seems to work fine, emulators etc.

Though one game backup I had that was working under 3.40 OE and 1.50 isn't working now, the image that was the correct game image is now replaced with the grey image.

I'm going to try to load it again when I get home and try again.

I tried using the different options in registry 1.50, 3.xx, trying OE isofs legacy -No UMD, Normal, m33 driver, and Sony NP9660. same effect not able to run. error or freezes on black screen, able to power down still after holding it in. It is an iso so its not in the game 150, 303 etc folders.

I may have to re-encode into the new version, I'm just wondering why it changed when I'm still using a 1.50 kernel and now the only difference is 3.71M33
Any help would be appreciated.

What game is it? Try changing CPU speed to 333MHz as well.

[PsychoticSmiley]

Already using 333. LocoRoco.

Already using 333. LocoRoco.

Has to be a bad ISO - try re-dumping the UMD, why it worked on 3.40 OE I'm not sure, but I have Loco Roco and it works fine on 3.71 M33.

[PsychoticSmiley]

Figures, I'll have to reload it, I'll post results.

[ipeelscats]

My battery is fully charged and i am getting the battery message when i try to install. i am installing from 3.52v4. What am i doing wrong?

[Acerthief]

battery message? you mean that it's not enough power?
try it with your AC adaptor in.

[ipeelscats]

Tried using the cable and also draining and refilling the battery neither works.

Hey x3, can I just say THANK YOU!!!

It's bloody nice being treated like a human when you have questions to ask that you hope others can help with and you've been an huge help!

I'm always one to search and try to find the answers without them being handed to me on a platter, some guys on other boards expect you to know the answers and gives the impression any questions are not welcome. I just didn't want to brick my PSP and wanted to get a clear picture of how to do it right the first time.

You've restored my faith in helping and I hope I can return the favour to someone else as I learn all there is to know about PSP.

Cheers mate!

[PsychoticSmiley]

Wow, regarding loco roco, I re-loaded the iso and it works fine.

I've been able to use PspTube under 3.xx as well.

3.71 looks to be running sweetly.

What are the differences with 3.71M33-2? is there any bonus over 3.71M33? I'd rather not use pandora's battery to downgrade then re-upgrade to 3.71 if I have to.

[ap_ichor]

Hey guys, hoping you can help me out. I upgraded to 3.71 M33 and successfully installed the 1.50 kernel update, and none of my emulators will run. ISOs work fine, it seems.

It either goes black and shuts down the PSP (crashes) or gives me various error codes including 8002014C (firmware installed doesn't support homebrew I think) and 80020148 (incorrect PRX type?).

Thanks in advance for any help.

(Maybe I need to format my memory stick? I dunno).

3.71 M33-2 is mainly a bug fix release. No need to downgrade again and install... just run the update from the PSP. Takes like 5 seconds to upgrade.

Did you try placing the emulators in PSP/GAME150?

[ap_ichor]

Let me try that after I format (don't worry, I had it all backed up on my desktop). I'd have to set the kernel to 1.50 via the recovery menu for M33 right?

No need to set the kernel to 1.50. Anything placed in GAME150 will force the PSP to use 1.5 kernel.

[ap_ichor]

Then nope, doesn't work. PSP just goes black, shuts off.

Moved all emus back to GAME folder where they worked in 3.52-4 M33, now I get error code 80020148 on all of them, or they crash the PSP (RIN GB/GBC emulator does this). Cave Story (freeware homebrew, so I know you can run the homebrew at least) and FFVII disc 1 run perfectly fine (FFVII is of course an ISO).

Give eLoader a try:
http://forums.exophase.com/showthread.php?t=3540

Also, if you want to run 1.5 homebrew from the GAME folder, you'll need to set that option in recovery to 1.5 kernel. Cave Story works since its written for the 3.X kernel.

[ap_ichor]

OK that works...but it's still pretty annoying to have to go through all that. If they can't be run normally, I might Pandora back to 3.52-4...

Hello I'm considering getting a PSP Slim real soon and I just need to get some facts straight. How would I get 3.71 M33 firmware on my PSP if I have access to a homebrew enabled PSP 1.5 CFW? I would need to get to 3.60 M33 on my PSP before moving onto 3.71 M33. I understand that part.

Let's say I get a new PSP slim and it has 3.60 or 3.71 firmware on it. I would first have to get to 3.60 M33 to move onto 3.71 M33. How would I upgrade to 3.60 M33 CFW? Would I follow the instructions on how to make a service battery (Pandora's Battery), but instead of using the 1.5 FW update, I replace it with 3.60 M33 CFW update? And then I'd revert the battery back to normal, and follow the same steps for making a service battery except this time with 3.71 M33? I'm very confused...please clarify for me. Thanks!

[ap_ichor]

After using eLoader I got pretty sick of it (crashed upon load of Genesis ROMs, crashed at exit of gPSP[??!!]), so I switched to 1.50 kernel again in the recovery menu and everything works fine again!

Weird, but...I'll take it! Hopefully my ROMs don't crash at times like they did on M33 3.52-4...my GB/GBC ROMs crashed all the time at varying intervals...just froze and shut down the PSP. Anyone know why that was happening? I tried multiple emulators, multiple copies of each ROM and they still did it. Checking now if turning hard reset off on homebrew will somehow miraculously fix it.

(Edit: was just playing UMK3 for SNES using SNES9xTYL 0.4.2me++ and I got a red screen of death (I only get these in this emulator) and it said something about read/write fetching being the error or something...very weird. Never got that before. Anyone know why my ROMs/Emus crash?)

Thanks for the help all.

Too many steps here... Alex released a new version of the unbricker / downgrader that will allow you to restore directly to 3.71 M33-2. No need to install 3.60 M33.

Personally I haven't tried the GB emulator, but gpSP works fine here and doesn't crash. As for the error with SNESTYL, that's nothing to do with the firmware, just a bug in the emulator itself.

You need to install 3.52 M33 and then install the 3.52 M33-4 update before going to 3.71 M33. Other than that, there's nothing else to do.

Very strange error. Can you try running KeyCleaner (http://forums.exophase.com/showthread.php?t=1238)? Analyze your idstorage keys with it and fix any corrupt keys it reports, except for key 5.

[RETHINK_THAT]

One note - because this custom firmware updater runs the actual 3.71 updater, your keys must be good before doing so. The cfw updater will unpatch key 5, but all other keys must be good or the 3.71 updater will quit without updating. This means that people running on a phat PSP should check their keys beforehand. You'll find my latest KeyCleaner here in the PspDevelopment forum.

All the keys reported by KC should be good, with 0x42 and 0x46 being clear, and key 5 being patched. The type of patch for key 5 doesn't matter, so long as it's just a patched key 5. If this is not the case, fix the keys before trying to update.

I ran the key cleaner v1.4 and it said everything checked out, but when I run 3.71 Updater it always says : Verifying 3.71PBP...Cannot open file (0x80010002).

???What am I supposed to do?

Make sure the EBOOT size is around 22.5MB. Format the memory stick. If it still doesn't work, most likely scenario is that you have a faulty memory stick.

Alright, it workded. Thanks a lot! The only problem is now the 1.50 kernel is confusing me. When I put it just at the root (for me it's K:/) it just sits there. It doesn't come up as a game or anything, it's just there. Am I supposed to do something with it or do I just let it sit there?

Well if you have a TA-082 mobo and you're not sure that your keys are clean i wouldn't do it, cause that's how I bricked mine on accident (but i have pandora so)

I'd recommend Using KeyCleaner v1.4 (http://forums.exophase.com/attachment.php?attachmentid=3013&d=1189919372) first and clean up your keys.

But again, if you have a TA-082 do NOT unpatch key 5 or else you'll PSP will brick.


I remember the installer looks at key8, but you'll need x3 to comfirm that.

for me, i used the pandora to flash to 3.71M33, which skips the key check.

Ok then... thanks for the help anyway.
Soo.. i guess x3sphere i need a little bit of help with the key cleaning... i have done no downgrades what so ever.. only have done the firmware updates from this site... so i don't see how downgrades could have affected keys.. do i actually need a pandora battery like thief has or do you have some miracle idea that will help :huh:
Please try help
Thanks if you have any idea's =]

Oh and thanks thief for the keycleaner link ^^

[x3sphere]

ok... i have the black screen up during the update... and this is what it says

Verifying 371.PBP... ok
Verifying umodule.prx... ok

'some of you idstorage keys have not the correct values, probably due to a downgrader. In order to continue, press x to restore the correct values, press R to exit'
i read something somewhere similar to this and he bricked his... <_< do i have to do something seperate and fix the keys? or do i go ahead and let the psp work itself out by pressing X

That's normal if you have a TA-082/86 motherboard. You need to press X

[frozen-flame]

Ok thanks, i'll try the update again later today, but thanks in advance for the help if it all works out =] you guys helped heaps cheerz

Alright... i hav upgraded my psp from version 1.50 to 3.52 M33-4 n when i try to use this firmware... it says it can only work on psp that has version 3.52 m33-3 or higher but mine is 3.52 m33-4. What is the problem here and how can i fix this to make this work?

3.52M33-4 IS higher than 3.52M33-3.

PSX games work on 3.71 M33. Also if you follow the old Pandora guide you can create a memory stick that has firmware 1.50 on it.

No need to re-do the battery steps, just the memory stick part.

There is also a recovery folder available, this worked to downgrade 3.52 M33 and below, not sure if it works with 3.71 M33.

Try formatting your memory stick. If that fails, then try using a different stick.

hi, i have the 150kernal_addon2 and im running 3.71m33-2, tried to install it but it said something about the 150.pbp not being there and then restarts... any ideas why this is? also is this gonna take me right back to 1.50?

all help appreciated thanks

[Acerthief]

nope this won't bring you back to 1.5

your 150.PBP (be sure to name it 150.PBP) and put it at the root, or "ms0:/"

Or maybe you have a corrupted PBP in your hands.

excellent, thanks mate, got it all working... however, i've now run into a new problem. i installed the custom fw extender 1.8.1 after installing 3.71-2 and 1.50 addon 2 and was loving it, only thing is it seems to have caused a few problems... im no longer to get my vsh menu up anymore using select and i cant get into the config menu in the recovery mode everything else there works but the config just restarts the psp after producing a blank screen for about 1 min... i deleted all the files for the extender but i still cant get them to work. i need to get into either one to stop the umd drive starting as it starts over all my iso games. any help on this would be really appreciated

Hi guys...I recently bought a white PSP with a 2gb memo and it has a 3.40 OE-A firmware

I have a few questions...
1.I don't have a AC adapter(therefore I cannot upgrade with Pandora battery)

2.I s there another way to do the upgrade(is this the way posted on the sticky topics) without Pandora(it is to complicated for me to upgrade with Pandora)

3.If there is a way can you please direct me to the threads or give me a manual step by step how to do this...

Help a guy...I never done this and this is my first encounter with a PSP...

[Acerthief]

1) get one. Recommended.

2) of course you can update to 3.71M33 without pandora.
First, upgrade to 3.52M33 (http://forums.exophase.com/showthread.php?t=2732), and then add the Update-4 (http://forums.exophase.com/showthread.php?t=3185&highlight=m33+update) patch,
then upgrade with this guide you're posting.

After that, add the Update-2 patch (http://exophase.com/files/psp/m33update2.rar) and the 1.5Kernel-Addon (http://exophase.com/files/psp/150kernel_addon2.rar).

3) Answered above. :D

[Bakutaj]

Thanks a lot...I heard tha USB charging is bad for the battery...BUt in my country all Play Station program is freaking expensive...They will charge mi with 20e for AC adapter...

but it must be done...I heard rumors about Survival packages that goes for a small amount...I think there's an AC adapter in it...

Yeah another Question is this 1.5 kernel necesary...Isn't his only purpose running homebrew programs(forgive me if this sounds stupid,I am beginer)

[Acerthief]

custom firmwares (like 3.40OE) before on phat PSP are 1.5 kernel based, so i would recommend letting the custom firmware on phat PSPs the "normal" stats, which is, having the 1.5 kernel.XD

Saves a lot of time on homebrew users, like me ;)

[SauceyWombat]

I found this on QJnet. Dark Alex has just released the newest updates to 3.71 M33; which brings us to 3.71 M33-3 (http://www.qj.net/Dark-AleX-releases-CFW-3-71-M33-3-PopsLoader/pg/49/aid/107198)

What's changed or improved:
- Fixed a bug in access to flash by usb.

- HEN core: kernel prx's with syscall exports work again.

- PSP Slim: programmers can set the size of user memory to 52 MB by using a sfo flag.

Check sample in sdk for usage.

- March33 NO-UMD driver:

* Fixed a bug that could hang the psp when exiting with home.

* Fixed compatibility issue with Castlevania Dracula X Chronicles, and maybe more games.

- Vshmenu: it wasn't displaying properly with psp slim TV-OUT due to the change of resolution. Fixed.

New & improved Popsloader!
Support for 3.71 and 3.72 pops has been added. Note that 3.71 however will not appear in the list in 3.71 M33 as it is not necessary.

There is an "Easy Installer" for 3.71 M33 (http://pspupdates.qj.net/3-71-M33-Easy-Installer-install-CFWs-the-easy-way/pg/49/aid/103185), but it doesn't seem to work on computers running Windows XP. You'll need to be running Vista. I've no idea if it works on Mac computers.

The 1.50 kernel addon cannot be installed on a Slim...

Anyways nearly all homebrew is now written for the 3.X kernel so there isn't much need for 1.5. Though eLoader will run most of the older PSP applications that were written for 1.5.

Are you sure you need to use popsloader? You don't need it to run PSone games, only to run older versions of the emulator. Generally I've found the 3.71 pops to work fine with most games.

You'll need a "Custom Firmware". In this case, 3.71M33. but you're only way is to use a Pandora Battery and a magic memory stick. The guide to make it is stickied in FAQ and Guides Section.

Turn off your PSP completely (holding on to the power button up for 10 seconds)

Hold R button and turn on, You'll be in the Recovery menu.

Choose "Configuration". (Press X to go in)

and You'll see the "Set GAME folder kernel", press X to change it into 3.52.

Last, choose BACK, and then EXIT.

You probably have a hard downed PSP. Meaning, it was downgraded by hardware not software. The Sony updater does not seem to run correctly on these PSPs so I think you will need to use the Pandora battery method to get to 3.71 M33:

This obviously doesn't make much sense as I have 3.52 m33-4 (it even says it under system info.)

as per the guide I've put the update folder under psp/game then put the 371.pbp into the update folder (this file is 23,094 big). oh and the battery is 100% charged and plugged in...

can someone please tell me where I'm going wrong.

Cheers


Go to Recovery Mode, choose "Configuration" -> "Set GAME Folder kernel" to 3.X

ok, I have version 3.51 M33 and i want to upgrade to 3.71 M33. I haven't heard anyone in this thread talk about having 3.51 M33 so would I be able to go straight from 3.51 M33 to 3.71 M33 or do I have to downgrade then upgrade? Can someone give me the best solution to getting to 3.71 M33? thanks

No, you need to install 3.52 M33 first. Once it's installed, apply the 3.52 M33-4 update (http://forums.exophase.com/showthread.php?t=3185).

Then you'll be ready to upgrade to 3.71 M33.

ok, I looked at the 3.52 M33 install guide. do I have to downgrade to 1.50 before i upgrade to 3.52 M33?

Nope, you can install it straight from 3.51 M33.

hi iam just asking about 3.52 as i tried to download it worked fine on the creator but when i tried to do the updator it stops at the psp screen

[itsadamlikewhoa]

so wait, "Addon for kernel 1.50 version 2" is what i need for a phat PSP to run without the "loader"? ----> it's to add onto "CFW PSP 3.71 M33-4"

Yes, that's correct.

I just finished upgrading to 3.71 and when I try to access my memory card, all I see is a file called UMD9660.iso. Can I not access folders anymore?

Press select at the PSP's main menu screen and make sure USB DEVICE is set to Memory Stick.

Wrong thread for this but yes you can downgrade 3.90 by following this guide:

There is one catch though - you will need another PSP running custom firmware to complete most of the steps in that guide. So hopefully you know someone running custom firmware who will convert the battery and install the required memory stick files for you.

Check Recovery Mode, the GAME folder kernel needs to be set to 3.52.

Go to the Recovery Menu, select "Configuration" and you'll see a Game folder kernel, change it to 3.52.

It's in the Configuration section of the Recovery menu. Hold R while booting up your PSP to access the menu.
