sounds like a driver issue..try re-install the drivers or try another usb port see if its ok.
Added on June 4, 2012, 10:27 ama lot of those facing problem mostly i think due to either not performing a data wipe, or missing a step. cause seriously a lot of us who are not facing much probs ( other than the highlighted in FAQ) , now its already under nightly build which means it is pretty stable.
from the time the experimental was released i have been on it. and i cant imagine not having it. batt life is great. the available settings,themes, etc is great.
in the even you do decide to get cm9. please:
1.Full Wipe/factory setting
2.Wipe cache/clear dalvik
3.Copy GApps and CM9 ZIPs to your internal SDCard
4.Boot into Recovery
5.Flash CM9 zip from internal SDCard
6.Flash GApps zip from internal SDCard
7.DO A DATA WIPE / FACTORY RESET (otherwise your device will be stuck at boot)
8.Reboot
try to avoid using batch TB install. make sure only restore APPS and not system stuff. if possible avoid restore completely. some ppl face issues restoring certain apps some dont. so its up to you if you wanna try. i personally didnt. i started from scratch.
Nais. Thanks for the advice! I guess I'll make the plunge later when I'm free. I wont be missing alot since I just flashed to ICS stock. Pretty much empty right now.
