PRS-T1 Problem with rupor's AMR 20121220

Hi,

I wanted to update my rooted PRS-T1 to the newest firmware/root package, but I wasn't successfull. Here are the steps I followed:

• reverted to the original state using my rescue dd image
• updated to 1.0.05.11130
• repartioned the reader to get more space for apps ->everything worked fine afterwards -> Yes!!!!
• refilled the reader with my books
• copied the sdcard-directory and PRS-T1 Updater.package from AMR 20121220 to the READER partition
• rebooted with HOME and MENU buttons pressed

However after the reboot, although the first home screen showed the changes from the root-package, the third homescreen with the applications did not appear. The "script.log" file does not show any errors except "Checksum file not found or zero" in the second line. Tried it two times without luck.

Any ideas what could have gone wrong?

Thanks and best regards,
Joerg
