Firmware Decrypt

[juusso]

The latest SamyGO patcher (0.31BeteBlue) makes all the job without editing. I mean no problem with B-FIRHRDEUC. Use original.
But maybe your problem is you`re trying to open with wrong application. Use 7zip or far manager to check what is inside exe.img or rootfs...

Thanks for the hint. 7zip did the trick. I didn't know that the img files are compressed as well. I just looked at the contents of the files with the hex editor and I couldn't see anything. Still, SamyGO patcher (0.31BeteBlue) downloaded yesterday needed modification for B-FIRHRDEUC. I modified this line to include my firmware:
BDd=["B-FIRURDEUC","B-FIRHTBEUC","B-FIRHRDEUM","B-FIRHRDEUC"]
but the script still didn't find the XOR Key. I didn't try to fix the logic, so I just hardcoded it to
keyData = 'B-FIRHRDEUC'
in my case and it worked.
Hope this helps improving SamyGO patcher!

Hope it helps.

hmz....maybe there is something with the file I downloaded. Can you pls just upload the samygopatcher file.

[juusso]

you`ve got link to repository, what else do you need
(save as... on Download link)

btw, same with latest, 1053 firmware:

Great job guys! Thank you!

My firmware is slight diffrent (B-FIRBP7WWC) and with every version (here I try to decrypt an old 1003.1 (the latest is 1010.0)) I get this:

I know we're almost there to decrypt B-FIRBP7WWC as well, just waiting confident

solution is quite simple, btw. try this version http://samygo.svn.sourceforge.net/viewv ... ches/pcre/ but it needs also python module "re"
