What To Do After DownGrading

Team M33's: 3.71 M33 Custom Firmware
If you have a PSP, This firmware is essential, Its 3.71 mixed with 1.50 so you can play your PSX games without the need for a PS3 and all the other features 3.71 has, It other best strength it it can launch homebrew just like a 1.50(slim has compatibility issues) and also launch ISO's straight from the GAME menu, plus many more cool mods.

wow, finally the final copy relased

now offically the 2.5/2.60 is downgradable, this is a holy day in psp scene

[Calo]

i am a 1.5 no use for this, i just want the 2.71 to be decrypted.
but now with this downgrader if your psp brakes you have a 80%
chance of getting ur psp back to 1.5 if you get a new one.

im a total newbie to all thins upgrading downgrading business but my psp was 2.5 factory when purchased and ive upgraded to 2.6 so do i need to use the 2.5 or the 2.6? and is this final version 100% chance of no brick?

[Man.]

I you can't use a factory 2.5 or 2.6 (but some people have tried and been successful) psp as for the chance of bricking I dont't know

and SHAZ use the 2.6 download, there is always a risk when using flash

I downgraded my factory 2.5, it's bullshit about that factory stuff :rolleyes:

[Calo]

no it was just unknown if it would work when the downgrader was first released but now we know it works perfect.
