So after a bunch of issues getting this KF back to usable using a factory cable I am still having issues. I have installed all versions of TWRP from 2.2 to 2.6. I have tried flashing the stock ROM on each TWRP version 3 times (just to be sure!). In every instance, the KF gets stuck on the stock boot screen. Sometimes it would come up with the stock message saying it needs to restore and press the power button. I then press it, and it goes back to it. Most of the time it just stays on the boot screen with no restore option. I have used KFU, fastboot, unbrick, and pretty much anything that was out there and still NOTHING but a boot screen. Does anyone have ANY options for this besides trying to convince Amazon to exchange it?
