skullpr | May 15, 2008 | 12:37 pm

I’m currently on 3.03 OEC…do I use the same method as “Upgrade from 3.10, 3.30, or 3.40 OE-A” to upgrade to 3.90 M33-3? Can I jump straight to 3.90 M33-3 or do I have to go through other versions?

Big Monkey | May 21, 2008 | 11:23 am

You should be able to use the same method as 3.10, 3.30, and 3.40 OE-A to upgrade. Don’t skip straight to 3.90 M33 though or you will probably brick.

You need to use a pandora battery to downgrade from that version, but until we get another psp to test with we can’t make a guide for using the pandora battery yet.

Help please, i do have 3.10 OE-A firmware on my

Alisha | September 10, 2008 | 3:10 pm

Help please, i do have 3.10 OE-A firmware on my psp, and when i see in the recovery menu i do have 1.50..
Tell me should i do step 4 now or not ?? because here above it says ” If your PSP is already a Custom Firmware 3.10 OE-A, 3.30 OE-A, or 3.40 OE-A and you want to have the NEW 3.90 M33-3:
~
Go to the Custom Firmware Upgrade and follow the instructions there. Note that you will not have to do the KXploit Permanent Patcher in Step 4. ”

But when i see Step 4 it says : If your PSP is already a Version 1.50 or you have just downgraded to 1.50
go to Game –> Memory Stick and run “KXploit Permanent Patcher.” This will patch the firmware so it can load unkxploited eboots.
This is only for Version 1.50.

Please tell me what to do ?
thanks, greetings Alisha
