Confused - working TWRP, no Fastboot, boot-looping CM 10.2
I have bootloader 10.6.1.8, TWRP 126.96.36.199 and until this morning a working CM10.2 (latest stable). The device began to switch itself off randomly a few days ago, so I used that as a reason to try Omnirom 4.4.
So, I followed this: http://forum.xda-developers.com/show....php?t=2575727
And when I read the line "ONLY WHEN YOU ARE ON THE 4.2+ BOOTLOADER", I looked up what 10.6.1.8 was and decided (rightly or wrongly) it WAS the 4.2+ bootloader. So I flashed TWRP 188.8.131.52 for kitkat.
That resulted in a split screen TWRP, which I managed to use enough to restore my backup (including recovery) and the tablet rebooted into my old working ROM (yay!)...until I rebooted into the recovery again and tried to flash last nights nightly 10.2 build (to see if that solved the power off issue) which failed - and now my ROM bootloops.
Where I am now:
- I can get into fastboot, my device manager (on two machines, a Win7 x86, and a Win8.1 x64) shows the Asus bootloader device, but fastboot shows no devices. ADB shows no devices as well.
- I can get into TWRP, but I cannot see all of the zip files I put on my external card. I put a new ROM there, and TWRP just doesn't see it. So I cannot flash a new ROM. I've tried re-flashing an old version of CM10.2 I found on my internal SD, but that also bootloops.
- The ROM loads up until the lockscreen, where it bootloops. Even when it tries safe-mode, it loops again. My computer see's the tablet when it's booting (if the cable is plugged in at the time) but it loops before I can put anything on the internal SD.
Before I do anything else....what do I do?
(Thank you for any help you can give, in advance).
