Ok, I'll try that although I used psardumper last time so I don't think it's because of Devhook Installer. I'll try this anyway and report the result later

Sorry if I didn't mention it before that I didn't usw devhook installer, it was a bit offtopic.
But it worked now! I used your Devhook installer 0.6f to extract the firmware 3.11 and then I used devhook 0.52 with
devhook 0.51 Beta for 2.71 HEND to emulate 3.11.
Maybe it didn't work earlier because I had to extract the DATA.PSAR with a pbpunpacker (don't remember the correct name).
Big Thanks for devhook installer Sleepy! yay, got 3.11 now

Ok, I just want to add that I had to restore the settings to default because otherwise I couldn't use the internet browser. It's no problem, but I only wanted to say this because maybe you didn't know.
