I'm having a problem with my Kindle 4 NT. I used Kubrick 3.6, and my kindle now just loops at the startup screen with a green light. I can still boot into USB downloader, and all that. But it won't load into the KindleOS. Not sure how to fix? I've re-done the process, erased all the partitions with Kubrick, same thing. Any advice?
edit: Fixed the problem. Not sure how, but the mmcblk0p1 partition was corrupted. (Used SSH to try and mount partition, wouldn't mount. Dmesg revealed "JBD: no valid journal superblock found") I downloaded a new mmcblk0p1.img from
