3.40 OE-A Install Guide

Hi guys,

I have an old original 1.5 FW PSP. I have been running emulators on it, and I found an old Japanese web browser that works for checking out sites on the Net. I have one UMD, but I've only used my PSP to play emulator games (lol, $200 PSP to play a $10 NES game)Anyway, I was just curious as to what was out there new for the PSP and I came across Dark Alex's amazing work, which lead me to this thread.

I have some quick questions, that I can't seem to find the answers to anywhere:

1. If I upgrade my 1.5 to 3.40 OE-A can I revert back to 1.5 if I want to in the future?

2. What features does 3.40 OE-A have that 1.5 doesn't. specifically, does it have a built in web browser? Does it have an email reader? Does it emulate PS1 games, etc..

Please keep in mind that I haven't experienced any firmware other than 1.5.....so if 3.40 OE-A has all the features of the official Sony 3.40 FW, please list some of those features for me.

I've never upgraded the FW before, and I want to find out ahead of time if it's actually worth possibly bricking my PSP to not gain any more functionality than I have now with 1.5

Thanks guys,
Bob

1. Yes, it's very easy to revert, we have a guide on how to do it here on the forum, very easily-accessible.

2. It does absolutely everything 1.5 does and more, quite simply put. It has built-in devhook which will emulate all the way up to whatever the custom firmware is, this being 3.40, which devhook only emulates to 3.11; It's also alot easier to tweak settings though the recovery menu; it has a recovery from semi-bricking; it has support for all homebrew and emulators 'n' such; you can flash custom themes, therefore customizing the look of your PSP's XMB. it does everything 3.40 does, being the built-in web browser, the RSS feeds, compatibility for h264 mp4's, WMA and Flash compatibility, and etc.

Also, there is little-to-no chance of bricking; that being said, there is no guarantee, but if you follow the direction 'n' such it's probably 99.9% chance that it won't brick.

Wow, thanks for the super fast response. That's the kind of answers I've spent two days trying to find.

I think I'm going to try this out later today and see what happens. As long as I can revert back to 1.5, I'm up for trying it.

Now I'm off to try and find that guide to downgrade back to 1.5. I need to see if it requires Lumines/GTA or whatever, since I don't have either one of those now.

Thanks for the input! If you have a quick link to that guide I'd appreciate it, otherwise I'll post it here once I find it :)

Yes, I'm still using 1.5

I just wanted to figure out when I do upgrade to 3.40 OE-A if I could go back to 1.5 if I ever needed to.

I've never upgraded my FW ever, that's why I'm still running 1.5. Hmm...now all I need is something that will download my email to the PSP and I'll be golden. Thanks!

Well, you can always use the web-based email stuff, like hotmail and yahoo 'n' such, those work in the PSP's web browser.

then during the process of making DATA.DXAR, did the program say that the SHA-1 is incorrect during the validation?
try to make the DATA.DXAR, and this time see the whole process, and especially keep an eye on the SHA-1 validation process, and see if the results come out in green text or red text.

no it says "3.40 OE-a DXAR update maker by Dark_aleX.
Uses code of psardumper *pspPet) for psar extraction.
Opening and checking 150.PBP...
Invalid 1.50 update file (3)

see it did that earlier on me so i just d/l'ed the correct 3.40oeflasher with all the files in it since i couldnt make the dxar file well it makes it but the file is 0 kbs so like i said since it wouldnt make the file i just skipped that step and d/l'ed the 3.40oeflasher files with the already made like 17.6 dxar file , so im confused why its not working

Click properties on the file an ensure it matches with the following size: 13,900,225 bytes

If the file size matches, you might have a fake memory stick. Are you able to try with another?

Glad you got it working :smile:

Fake memory sticks are slower than real ones, so when you're creating the DXAR, it's putting a lot more stress on the memory stick than a simple save read / write. That's why most fake memory sticks fail at this point.

3.03 oec to 3.40 question

I have the 3.03 OE-C and I see a GAME150 and GAME303 folder. Do I still use the GAME150 folder to transfer 340oeflasher? Just want to be ablsolutely sure before I start this and not brick my PSP. ALso does upgrading to 3.40 solve the problems of "GAME COULD NOT BE STARTED (80020321)" popping up with my 3.03 version? Thanks.
