I hate to bump an old thread, but I've recently hit what appears to be a related issue (WiFi stuck off), though perhaps there are some twists to my tale - and I'm still stuck.
I have an early TF101 (B50) and have had it rooted with stock ICS for awhile. Everything has been mostly fine, but I decided to give CM9 nightlies a try.
Here's where my issue differs from the others in this thread. With the CM9 nightly flashed, I was stuck at the boot animation (for hours - left it overnight with no progress). I restored my nandroid backup and now I had the "WiFi Turning on" issue that others here have experienced.
I've tried multiple other ROMS (latest of AOKP, Gummy, and Prime 1.6), with complete wipes, and in each case, I was stuck on the respective boot animation. This completely mystifies me, but it may not be related to the WiFi problem. After each iteration of failed ROM flashing, I can restore my nandroid backup (the rooted stock ICS) and everything works fine EXCEPT
Following the suggestions in this thread I've tried flashing a new stock ROM (from http://forum.xda-developers.com/show....php?t=1514658
) and while that doesn't stick at the boot animation, it also doesn't fix my WiFi. I also tried a.mcdear's suggestion in http://forum.xda-developers.com/show...85&postcount=7
, but I did not have the file wpa_supplicant.conf in my /data/misc/wifi directory. The only file in there was an empty file called "status." Just for good measure, I tried renaming it, but no joy.
At this point, I'm out of ideas and have a severly crippled TF. I would appreciate any suggestions or ideas from the community.
