Hi, I need your expert opinions regarding my S7. It refuses to turn on or power up either with the battery or the charger plugged after an "unsuccessful" firmware upgrade. Did I brick my tablet? I have already successfully upgraded from the stock 2.1 to 2.2.2 (Indo ROM) previously. Then recently, my S7 hung on the "IDEOS" logo after powering-up. Tried hard reset, recovery and fast-boot to no avail. So I eventually decided to re-flash via SD using 2.2.2 Indo ROM again. During the upgrade process, the progress bar stopped midway and my S7 reset. Tried to repeat the process with similar results, simply the upgrade failed. After that, my S7 does not turn on anymore. I tried removing the battery and plugged the AC charger but still it won't power up. I don't think this is a hardware issue and I suspect it has something to do with the failed upgrade. Any thoughts on how to resolve this issue? Thanks in advance!
