Hello,
I tried to flash the 4.0.0 firmware using the files provided in
http://pastebin.com/Wdw4L7yT (used the Mediafire mirror). I flashed the firmware with the tutorial provided at
http://www.mediafire.com/view/?xrn3v3ln6cn2n75.
After following all the steps in the tutorial I end up in a Kindle with 4.0.0 but I am NOT able to update, neither to 4.0.1 nor 4.1.0. All I get is the Error U006. How is this possible? I am not using any screensaver hacks. Is it possible that this image is not really "clean" and somehow jailbroken?
Furthermore, it is totally impossible for me to directly flash the 4.0.1 using fastboot and SSH. After the final reboot it won't start the main system and only freeze within the diagnostics system. Even trying to boot it to the main system using MfgTool ends with a frozen Kindle stuck in the diagnostics mode.
Can you help me?
