What is a PSP Nand

What is NAND: NAND Flash architecture is one of two flash technologies (the other being NOR) used in memory cards such as the CompactFlash cards. It is also used in USB Flash drives, MP3 players, and provides the image storage for digital cameras. NAND is best suited to flash devices requiring high capacity data storage. NAND flash devices offer storage space up to 512-MB and offers faster erase, write, and read capabilities over NOR architecture.


What is a NAND in PSP: Basically NAND where the operating system, idstorage, IPL, system settings, all the important things like that are held. In other words like the “Windows/WINNT” directory in a windows operating system.

The official usage of NAND is to make the PSP run. The unofficial use of the NAND is to restore bricks, and recover IDStorage, if our IDStorage becomes corrupted.

The size of NAND on a PSP PHAT is 32 MB and of PSP SLIM is 64 MB(Almost double)

NAND on PSP in another word is flash0.

Note:Β  NAND is unique for a PSP and a PSP should never be restored from another PSP’s NAND

It’s a good practice to backup your PSP NAND and store it in a safe place as this would the life saver if the PSP is bricked


How to install 5.00 M33-4 custom firmware

DA is back with 5.00 M33-4 custom firmware update.

Changes in 5.00 M33-4:
– Speed selected for umd/iso was not properly locked in some new games that used scePower_EBD177D6 instead of scePowerSetClockFrequency to change speed.
– UMD/ISO speed settings now apply to PSN games too.
– Fixed libupdown.prx connecting to instead of sony when npsignin_plugin checks for a new version and m33 update is enabled.
– Iso file descriptor was not closed in driver deletion
– Added a shutdown command to vshmenu.

If you already have 5.00 M33-4 custom firmware installed on your PSP you could either install via Network update using WiFi internet connection.If you don’t have a WiFi connection, you can download the update from here. Extract the files to your m0://PSP/Game folder and install using XMB menu

Credits goes to DA for his awesome work! Cheers

Note: IF you do not have any custom firmware installed on your PSP, read my previous posts on How-To install the same. Have fun!
