Unbricker for ALL PSP's inc Slim

September 28th, 2007, 18:54 Posted By: mikebeaver

Here is the thing we have all been waiting for (If like me you managed to brick a Slim, lol)

Hot off the press from m33/ D_A is the multi unbricker

Id like to take this oppourtunity to say thank you for all the hard work many people have put into this and for Mr Tutu Alek and Jas0nuk who have done the translation's, the one below is from Jas0nuk

Mike..

Installation:

- Skip this part if you already have a Pandora memory stick.
If not, format an MS using Pandora/C+D mspformat or any other tool
that allows the movement of the partition ~250kb from the first sector

- Cancel USB connection and remove the memory stick. Then re-insert
the memory stick and restart the USB connection.

- Make the PSP and PSP/GAME/ directories

- Copy "despertar_cementerio" to PSP/GAME/

- Download official updates 1.50, 3.40 and 3.71, and copy them to the memory stick root, renamed to 150.PBP, 340.PBP and 371.PBP

- Run the app under the 3.XX kernel (under a custom firmware, make sure the GAME folder is set to 3.XX kernel)

- Once finished, you'll be left with msipl.bin on the memory stick root.

- Skip this part if you already have a Pandora memory stick.
If not, use C+D msinst to install ipl on ms, or use the dd command in unix, or any
hex editor to write msipl.bin to sector 16 on the physical drive.

- Now you can delete 340.PBP and 150.PBP
371.PBP will be used for unbricking, so don't delete it.

- Now you have an universal Pandora memory stick ready to go, and you just need a proper battery.
If you have 1.50 kernel access, use the C+D tool. Otherwise, use cory1492's tool.
EITHER TOOL SHOULD ONLY BE USED ON FAT BATTERIES, AS THEY WILL CAUSE PERMANENT DAMAGE TO SLIM&LITE BATTERIES.

- The service mode fat battery and memory stick will work on any PSP to date.


Unbricking:

(Note that you won't see the unbricking menu on the slim, due to the different display drivers, so follow the below instructions carefully)

- Press X to install 3.71 M33. On the slim (blind installation), you will see the orange LED flashing,
which means that 371.PBP is being written. When finished, the orange and green LEDs will flash,
to show that it worked. Finally, the PSP will automatically switch off.

- On the fat, once finished, press X to shutdown.
Power on manually, press O at the Blue Screen of Death, and you will be on 3.71 M33

- Press O to install original 3.71 (rest of the process is the same as the 3.71 M33 installation)

- Press [] to dump the NAND to ms0:/nand-dump.bin.
Make sure you have 33mb (fat)/66mb (slim) free on your memory stick to avoid corruption.
The PSP will shut down automatically when done.

- Press L+R+HOME+start to restore NAND from ms0:/nand-dump.bin
This process is very dangerous, and you should only use it as a last resort.
It is physical restore process (not a logical one), and will try to make
a 100% clone of the dump.
If you are working with a dump that isn't yours, you will get either a brick
or a corrupt idstorage, depending on the firmware.
If, your PSPs NAND has more damaged blocks than the dump being restored,
you may also end up with a brick.

Works for both PSP and PSP Slim.

Updated Version added with English Readme and Sony Bugfix
