Kindle Touch does not boot
I'm new to the forum, found this great community when googling how to unbrick Touch
Yesterday after read for a while my KT stopped responding, the screen only display top menu bar, other areas were white blank. I turned it off by pressing power button for 30 seconds, but after that not able to turn it on anymore, nothing happened after press the power button.
So I decided to unbrick it, what I have done:
1. flash diag with fastboot, use kindleSelectBoot to get into diag mode
2. dd if=mmcblk0p1-kt-5.0.0.img of=/dev/mmcblk0p1 bs=4K
3. dd if=/dev/zero of=/dev/mmcblk0p3 bs=4K
Now the Touch can boot into main mode with kindleSelectBoot, everything seems smooth after boot - great. Now the problem is it can not boot without kindleSelectBoot - when I choose restart from menu it freeze at a tree and "please wait a moment while your Kindle starts up", press power button (and press for 30 sec as well) seems has no effect, nor green LED light. To turn it on again I have to connect USB cable and choose main mode in mfgtool.
I tried to restore factory default from menu, as well as "fastboot setvar bootmode main" and "fastboot flash kernel kernel-kt-5.0.0.img" but no lucky.
Is there anything I missed in the unbrick precedure?
