Hi all, I'm new into Android, I recevied OTA 2.2.1 update, it works after one day, when I power down and up, it went into continous reboot loop. I have take out battery to stop the loop, when I put back battery, I only see skateboard robot in the middle of the screen and stop there. I tried power + track ball, I can go into fastboot menu and navigate, the moment I choose bootloader, i cannot navigate to recovery or other selection, after few seconds it will do the following : SD checking.... Loading ... [passdiag.zip] it will stuck at loading, I can't do adb also because is not detecting my phone. Possible I brick my phone?? Any advice will be great. Thanks!!!
