    Huawei Ideos S7 does not turn on

    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!

    Can Adb detect your device?Does the screen or the capacitative buttons light up when you try switching on?

    I cannot do anything with the device. No lights, no response, no display when I turn the power button on. Same behavior even with the AC charger plugged. The battery doesn't even get warm to indicate that it's charging.

    Have you tried flashing back to original 2.1 and reflashing original firmware yet.

    This is what I intend to do, reflash with another FW version (2.1 or other 2.2); unfortunately the device refuses to power up preventing me from doing a reflash.

    I plugged the AC charger the whole day yesterday and still nothing happened. Are there any other key/button press combinations to at least bring the S7 to bootloader mode?

    1. Without battery connect charger and then power on charger. Let know if IDEOS is displayed on screen. Assuming ROM is corrupt.
    2. With or without battery but with charger connected and powered on press and hold Back and Send buttons then power up. Does the unit display a white bar in the middle?

    If any of the above symptoms is present, the unit can be rebooted in recovery via ADB and a stock firmware can be flashed. I killed my tab so many times like an over zealous modder and could recover back all the time. it did happen to me that the flashing stopped after about 5 bars and then on some other occasion at bar 12 or 13. On two occasions the lights will suddenly start blinking fast and flashing will not continue. Please let know.
