Help! Diags fails to start

[KarZh]

Hello guys,

I meet a problem when starting Diags.

I have successfully JB my KPW3 with firmware 5.14.3 yesterday using opening case and connecting serial port method. I got the root and installed jailbreak, KUAL and other great stuff.



However, when I try to JB my wife's KPW3 with firmware version 5.15.1, I cannot start Diags. Here is what I do, after enter uboot, I input bootm 0xE41000 then I go the error message: kinit: init not found!

I have tried “Format and overwrite FAT partition” and "Update using update*.bin file on FAT partition", so firmwire installed several times. I also tried reset from Kindle menu and "DO_FACTORY_RESTORE", nothing is a success...

Here is the log:

Hit any key to stop autoboot:  0 
uboot > bootm 0xE41000

Same problem today.
Resolved by flashing diags into fastboot
Download usb_diags image here
At uboot type bist fastboot
Use https://github.com/TobiasWooldridge/Fastboot-Kindle
sudo ./fastboot flash diags PW3/pw3-diags.img
sudo ./fastboot setvar bootmode diags
sudo ./fastboot reboot

In diag mode put update.bin in usb folder and reboot.
Everything fine now.
