@geekmaster: Thank you so much, I will try it.
I discovers that when
pcbns,serial, etc. is erased fastboot can't flash to mmc(Not only recharing problem - I've recharged a week
).So I rewrited pcbsn,mac,..., fastboot again and flash function run OK.
It work OK now.
Spoiler:
UPDATE:
Now I my kindle work but I must use imx_usb main.bin to boot, It seem that bootloader has wrong size or bist is corrupted.
I used
Code:
dd if=mmcblk0.img of=mbr bs=1 count=512 <--Get 512B mbr
dd if=mmcblk0.img of=bootloader skip=1 bs=512 count=734 <--Get 376KiB bootloader
Then my kindle's identity are empty ??? I must use fastboot to write it again and reboot KT, it can't boot, the screen is stand.
Next, I use
sudo ./imx_usb diags.bin it works and
sudo ./imx_usb main.bin also work.
