Update to to the M33 firmware then update to M33-7. You don't need to update from M33-1 then M33-2, etc. It's a cumulative patch.
Thank you
.
[edit]So, just one last question then
. When using 3.50HEN one can just update to the 3.51 M33 orig. rel. instead of going through 1.50 first right (would that remove the downgrading problem for unpatched TA-082 or higher mobo's?)?
[nvm]Answered myself in the first question;
QUOTE1 - If you are under official 1.50 PSP firmware, copy kxploitpatcher and kxploitpatcher% folders from "1.50only/" of this download to your "ms0:/PSP/GAME/" and use it.
2 - Once done it,
or if you are under any Special/Open Edition, copy M33CREATOR folder to your "ms0:/PSP/GAME" (1.50fw) or "ms0:/PSP/GAME150" (SE/OE)
3 - Download official 3.51 eboot, rename it to 351.PBP and place it on "ms0:/PSP/GAME/M33CREATOR/" or "ms0:/PSP/GAME150/M33CREATOR/"
4 - Download official 1.50 eboot, rename it to 150.PBP and place it on "ms0:/PSP/GAME/M33CREATOR/" or "ms0:/PSP/GAME150/M33CREATOR/"
5 - Go to Games/Memory Stick on your PSP, and execute "3.51 M33 CREATOR". Once finished, it will go back to the XMB.
6 - Go again to Games/Memory Stick on your PSP, and execute "3.51 M33UPDATE". You'll have to press X to agree to the installation.
7 - When finished, press X to shut down and reboot manually.
8 - Enjoy your 3.51 M33
