Using The Universal Unbricker To Unbrick / Downgrade / Restore Any PSP To 5.00 M33-4

Thanks, maybe the thread should be updated to inform other people?

Yes, good idea. I updated it.

Yes that means you have 3.71 M33-2 custom firmware now. The 1.5 kernel is a separate add-on, available here:

Download it and copy the UPDATE folder from the archive over to PSP/GAME. Then download the 1.50 firmware update (available here) and copy it to the root of your memory stick.

If you don't know what the root is, it's what you see when you first open up the memory stick on your computer.

Tnx you guys u guys the best and Dark ALex too....

Not yet.
We'll have to wait for DAX (Dark_Alex) to update the newest program.

I'm rewriting the guide with new instructions so that it works on 3.80 M33. Still though, it will install 3.71 M33-2 to your memory stick until Dark_AleX releases Despertar Cementerio v4.

Should be up later today.

I have got to step ten creating the memory stick but I have a problem. I'm not seeing the despertar application? I have copied the actual folder, should I have just copied the contents into the psp/game folder? Is there anything else I need to do?

Help?

Try turning off your PSP completely, take out the memory stick for a few seconds, stick and back in and turn it on. See if it works.

If not, overwrite the Del folder again.

Press select in the PSP main menu screen and make sure the ISO mode is set to Sony NP9660.

Hold R during PSP bootup and make sure both options in Advanced -> Advanced Configuration are disabled. If that doesn't help then the games giving a 80020148/80010002 error are probably corrupt.

My config setup is already disabled.. YES.. The game is corrupt! i've tested it to other slim psp 3.71 m33-2 (which is upgraded by other setup).

THANK YOU AGAIN... YOURE GREAT....

 

[booom]

can i make a pandora battery with 3.60 slim psp?? and can i change 3.60 with 3.71 m33??

 

[Acerthief]

You can change from 3.60 to 3.71M33 with this.

But this guide needs a PSP with a custom firmware built-in already.
