I've been working on a KF that was previously rooted - and now will only boot to this screen:
Attached - BootScreen
I was able to previously access TWRP, but now after trying to wipe the kindle, it will no longer boot to that.
When accessing the KF via a fastboot cable, this is how the device is recognized:
Attached - Driver
Running options in KFU, I receive:
Attached - KFU
I've had the most luck with the "KINDLE FIRE HD System.img Recovery Tool"
Attached - SystemImage
It allows me to remotely reboot my kindle, and says that it successfully writes a new image on the device(downloaded a fresh blank one) but the KF will boot to the yellow triangle screen every time thereafter regardless.
Any other suggestions on what I could do?
