FIXED. I bought an Amazon Kindle Touch KT3 refurbished and it came in Diagnostic Mode and Developer mode.
Followed "encol" and "NiLuJe" instructions.
On Kindle:
1) connect to Windows PC via USB cable
2) in developer mode screen, enter "USB device Mode" and then "ADB"
3) Press "execute test" and "exit code:0" will appear. thats ok.
4) Check that a device called "eanab" is now connected to Windows 10 machine.
On Windows 10:
1) download adb tools from
https://dl.google.com/android/reposi...st-windows.zip
2) extract zip content in a new folder in C:/adb
3) open CMD for windows
4) type "cd c:/adb" and press enter
5) type "adb shell" and press enter
6) type "idme -d --bootmode main && sync && reboot" and press enter
Kindle will restart in normal mode after 5 seconds.
SOLVED!!
Thanks.
