Custom Firmware 3.90 M33-2 Released

Dark_AleX has released update #2 for his 3.90 M33 custom firmware.
Changes:
- Improvements in plugins loading code:
- Fixed some problems with problematic cards due to filesystem not mounted.
- Now plugins should read the faster.
- Problem fixed with lines with spaces at the end.
- Added the rest of regions to the recovery option fakeregion.
- (PSP SLIM): Added patches in nand ipl to allow Booster multiiplloader and TimeMachine iplloader to boot from nand.
- Note: only 3.90 M33-2 and higher can be booted from nand in slim with those ipl loaders, not official Sony firmwares or previous versions of M33.
Changes in updater:
- The 3.90 eboot downloading code is now more stable, no more freezes after selecting AP
- Memory stick write in the 3.90 downloading code is delayed the maximum possible for faster operation (the system prefers big chunks of data written at once).
Download below, or grab it via the Network Update (Network Update only works with CFW 3.80 M33 and above).

i have 3.90 and i need to know how to switch to either of the 3.90-M33’s. that was more of a question rather than a comment but advice would be great! thx
same, i just upgraded without thinking, and i dunno how to switch to 3.90-m33
You will need to create a pandora battery and a magic memory stick. If you have a friend with a custom firmware psp you can easily create them.
how do u upgrade i’m usin slim so there’s no need to have a pandora battery rite?where do i put the folder?
you must use pandora if you have a slim with official firmware
i have a psp (4.05) can i downgrade it??
