Will test it asap, i added a logcat log in my previous post but Im not sure if it's the right one
Edit: Same problem, black screen graphical glichtes at the right side of the screen and no adb connection possible for me.
Just to avoid any mistakes on my side.. this is what I did:
downloaded your image file and copied it on my sdcard. Reconnected usb with phone started adb
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p13
Rebooted into recovery -> black screen with graphical glichtes.
To test adb connection: rebooted phone into recovery mode
-waiting for device
No reaction, adb shell not working too.
