thanks for a quick response.
1) I happen to have a slim psp with 3.60; i also have a pandora battery and a magic stick with 3.60m33. I prepared it before reading this thread but i've not tried it yet with my slim. can i follow steps in this thread to update my slim psp to 3.71m33-2 directly? or should i first update it to 3.60m33?
(note: i'have got a homebrew enabled fat psp thru which i prepared the pandora battery and 3.60m33 stick)
2) If i skip 3.60m33 and reformat my magic stick to follow steps mentioned in this thread to install 3.70m33-2 directly; when i try to move back to sony's firmware will it recover back to 3.60 (my original firmware right now) or will it recover back to sony's 3.71 firmware? just need to make sure what options i'll have before making the move
3) once i move back to original firmware from sony can it be detected somehow that this psp was once modified to install custom firmware? i mean is recovery to sony's firmware 100% clean? or does it leave some tracks?
thanks again

Following the steps in this guide, you can update it directly to 3.71 M33-2. If you try to recover the PSP after installing, it'll install official 3.71. And no, it can't be detected that the PSP was modified.

your posting in the guide to downgrade right now
All you need is
1)a phat PSP battery (buy it in any store, 3rd party not recommended)
2)a memory stick (128MB is good enough)
3)a homebrew enabled PSP (or look in the noobz.eu forums for people willing to help)
Yeah, if you have a spare homebrew-capable PSP (or know someone who does).
Just one more question: After this process is complete, can you use the battery and the mem stick like I used it before? If not, what do you recommend I should get to install the unbricker. Also, does this installation process have a chance of bricking the PSP?
-pls. post a helpful answer and thanks a lot

There's no chance of bricking since no files on the PSP's flash are modified during the process. Once you've finished yes you can use the memory stick normally but as for the battery you will need to convert it back. To do this, when you convert the battery for the first time make sure you choose the backup eeprom option as it states in the guide. Then when you boot up the battery application for a second time, an option to restore the battery by flashing the eeprom.bin back will appear.
That's what I did and I'd recommend it. That way you always have a backup plan for your PSP.
256MB stick and the Sony-branded PSP battery. Should run about $50 altogether.
I have a FF VII Crisis Core Ice Silver PSP from Japan. I have successfully gone through the steps and was able to upgrade my white Star Wars PSP with the Universal unbricker from 3.60 to 3.71 M33-2. Will it work on the FF VII Crisis Core Ice Silver PSP from Japan? I paid a pretty penny for this and I don't want to risk using the unbricker without expert advice. Please let me know. Thank you so much and thanks for the guide. I have upgraded my original fat psp and star wars psp to latest firmware. Now I wait for the faith of my ff vii psp. Thank you.
Woohoo!
No it does not remove the region code limitations, that's something that hasn't been done yet. There is a setting to fake region, but it is simply for activating firmware features such as P-TV that are exclusive to Japan.
Doubt in tutorial to create Pandora battery
Hello,
I am a beginner in these matters. I just bought a PSP Slim with FW 3.60.
I want to play games stored in my memory stick and I am a bit confused with all the forums I read...
I saw your tutorial (which I consider excellent) but in step 4 (Pandora battery creation) I have a doubt:
At some point you say:
"...choose the convert to service mode option. DO NOT USE THIS ON A SLIM BATTERY!"
Does it mean that I can't use this procedure in my PSP SLIM? If yes, at which point do I have a Pandora Battery?
Could you please help me to unbrick my PSP so that I can play games from memory stick?
Thank you very much

No need... you just need to be running at least 3.52 M33-3 or 3.52 M33-4 to install 3.71 M33.

No, that only means the process cannot be done on a Slim battery. You can only convert a regular PSP battery to Pandora. The newer Slim batteries cannot be converted through normal means.
