So I decided to pull my 7800 out of moth balls and noticed the 4.4.4 update.
Charged it up and booted it.
Wouldnt boot. Just got to the splash screen.
Fine; boot to recovery and kill the cache etc.
It would seem at some point I installed TWRP (v2.7?)
But idiot me, went and nuked the lot.
Now I have no OS, no back up.
Will still boot to TWRP, but booting to bootloader gets me no where. PC (Windows 10 if that makes a difference) just throws an error about an undefined usb device.
Have I killed it?
