SmartQ T20 really bricked never turns on
  • I was trying to update the firmware on my T20 when it suddenly turned off and it won't turn on again. It is relly bricked, since nothing appears on the screen. Doesn't matter how long I press the power button. The recovery power+volume keys doesn't work. I have charged it for about 50% before updating the firmware.

    I was wondering if there's any program like flasher-3.5 for Nokia N900 which allows you to flash everything to your device via usb, even if the phone won't boot.

    You should use the serial port on logic board inside the tablet. Or send back to seller.
  • Can you tell me more details about the serial port inside? What type of cable do I need? Is there any flashing software that can flash the firmware via serial port?

    Could you locate the serial port on these pictures?

    GND, RX, TX pins on the main board: http://images.imp3.net/article/2012/04/23/270036.jpg

    There is no cable for this, you need to bild one. I can not help you with software sorry. You need to do some research. I recommend you the slatedroid.com.

    (Let me ask a small question: Are you from Hungary?)
  • On my T20 I've found it sometimes gets into a weird state where it seems bricked.  I've found if I hold down the power button for almost 60 seconds (maybe more) it will click off. I can then hold down the power again and it will restart normally.  These systems have boot loaders that take care of flashing the root filesystem to memory. These boot loaders never get re-written when flashing the root filesystem. They could get the wrong parameters pointing to the root fs, but the flashing of the root fs from the microSD will still work. I guess it is in that weird state.
  • Dear Admin,

    My T20 died and wont start..I happened last night (18/2) while I was in the middle of downloading some application from play store.. It suddenly off and wont start, I did try to press the power button for almost 20 to 30 seconds but nothing happened.. I thought by leaving it charged the whole night would solve the problem, but I was wrong, it did nothing, The only thing I noticed was the heat at back of the tab..
    And when I pressed the power button, the result was still the same nothing happened.. I also tried pressing the power and volume control button at the same time for about a minute but still nothing happened..
    Can anyone or admin could help to solve my problem..
    FYI I bought this tab from smartQme international online store sometime last year, if I was not mistaken in May..
    I dont know what to do now, whether to send it back for repair which i think would cause me to bear a costly shipping and plus I need to deal with our custom some more.. which i try to avoid...

    I really appreciate and thank you guys in advance for your suggestion,opinion and help..
    Im looking forward for admin, may be, to give some useful suggestion regarding my problem ..
