Need help with kindle boot loop

[jsharp]

I have a rooted kindle that has been working great for weeks. Last night I plugged in my kindle to charge. This morning my kindle keeps looping. It comes up and says "kindle fire" then goes blank then comes back up with "kindle fire".

I plugged it into my computer, open the kindle fire utility, clicked install drivers, then told it to reboot normally. The computer tells me that the drivers were not installed properly. The kindle will not therefore reboot. Please help.

Mine started boot looping last night after I booted into TWRP to make a backup. Here is what I did to fix it.

How to solve boot loop issue on Kindle Fire TWRP 2.0?

Note – adb.exe is located in Kindle Fire Utility\tools folder or
C:\Program Files (x86)\Android\android-sdk\platform-tools.

Plug in USB cable to Kindle Fire on TWRP Recovery mode.
Bring up Command Prompt.
Key in adb shell.
Key in idme bootmode 4000.
Finally, key in reboot.
That’s it.
