    Heya guys, I was wondering, what is the latest official firmware ppl can downgrade from?

    So far i think it's 2.80 but I can be wrong!

    Also, it has to be able to downgrade to 1.50 in order to upgrade to the 3.30/3.40 oe firmware!

    Thanks

    The latest you can downgrade is 3.03 but you need GTA:LCS unpatched.

    Is there a specific reason as to why you need GTA?

    Is it to boot the psp games, cos i use Monster Hunter to do that.

    it works for both. i used it to downgrade my TA-079 like 5 times, and i used it to downgrade my friends TA-082. it just takes an extra step. it says on the screen that u it needs to patch ur mobo before it downgrades. it worked every time for me, and i never used winstaller

    3.03 is the latest firmware capable of being downgraded. It works on all motherboards to this date. You can use the link in my signature to downgrade from 3.03 to 1.50 then use the link to upgrade to 3.03 oe-c if you wish.

    I believe it is TA-079 to TA-086 because i used the 3.03 downgrader on my friends PSP and it worked no problem, it was TA-079.

    Check here.

    If you have any text in the selected are, they you have a TA-82 or 86 Motherboard and just have to downgrade a little differently.

    If you don't have any visible clearly visible text, then its some other motherboard and you can downgrade "normally".

    Bottom line is that 2.81 - 3.03 Any motherboard = you need GTA:LC (a early version that has the 2.0 update in it, later ones wont do since they are patched.)

    Any earlier PSP firmware version have downgrade programs available.

    Correct me if I'm wrong but its the same.

    Only thing is the downgrader wont ask you to patch the motherboard.
