First let me say, this is a really great forum - a lot of really interresting stuff for xoom owners.
After playing around with some different MZ604 ICS roms (CM9 KANG, Team EOS), there where no serious issues with my xoom. A couple of days ago, i got - after unplugging the charger - a sudden reboot. Afterwards i stuck in a bootloop (red M). So i jumped via CWM back to the latest stable nand backup.
But still bootloops. Factory Reset. Still bootloop.
Going xda - reading. Finding xoomforums: reading more.
Logically i did work thru every thread about bricked and softbricked xooms. I performed all the possible and impossible solutions, but finally i stuck in that annoying bootloop...
What i did until now (not in logical order):
- Wiping, factory resets in CWM
- Flashing stock img files via fastboot (boot, system, recovery, userdata)
- Locking, unlocking
- stock sbf via RSD-Lite
- and things i forgot
Everything i did: it ends with a bootloop. Sometimes the xoom is able to start up to the android splash screen (honeycombs, eos logo, cm9 logo) but there is point it freezes and reboot to the red M. Finally it stucks in bootloop.
I got normal response in fastboot mode, sporadically i got a short response in adb, but then the device reboots. For all flash-processes (sbf, fastboot, cwm) from different machines i got normal success, file checksums are ok, so far i conclude nothing is broken during this works.
Now i am at the point, thinking about having a defective logic board.
Because of the warranty void, motorola will not be willing to fix the board (not really surprising from my point of view).
But perhaps anybody has an new idea, what to do to reanimate my xoom? And is there a possibility to get a logic board (wifi only)? Anybody out there selling such (used, new) stuff (no luck via google ) ?
Regards, and thank in advance for any help!
