Asus Tf700 is unlocked and rooted on latest TWRP recovery, which does work. However, after making a backup with the new TWRP version, the tablet is stuck on the boot screen (spinning wheel). Last week I flashed a JB ROM, didn't like it, so went back to ICS with the .30 firmware. Flashed it using old version of TWRP from micro-SD card. Device has been working fine since then. I tried reflashing the .30 kernel again using the same method. It installs kernel, but no luck, still stuck on boot screen. Then I tried TWRP restore, using the new restore file. It restores, but goes to the boot screen and just spins. Any ideas? nvFlash is unavailable to me. What else can I do? Should I try a factory restore in TWRP? I'll keep messing with it later today, but any suggestions are appreciated.
1. What bootloader are you on currently? (See 4)
2. By flashing the ".30 kernel" I assume you mean flashing the .30 stock ROM
, am I right?
Your device went into a hung boot after making the backup, so I'm not really surprised it does exactly the same when you restore that backup.
Have you tried flashing .30 stock ROM again?
3. Which recovery do you currently have? As Tylorw1 said, if you flash a full stock ROM, you'll reflash everything, up to and including the bootloader and recovery.
4. If you still have fastboot available (pick the USB symbol instead of RCK after POWER+VOL_DOWNing), you might want to try to reflash either TWRP or CWM (http://forum.xda-developers.com/show....php?t=1926286
for the latter; I have VERY limited experience with the former and you may well have more than me
Updating your bootloader just to be sure
is recommended, as most current ROMs will not boot properly without it.
Has the fiddling brought any new points of view, or new discoveries?
