    I know, just follow the thread BOTH SECTIONS using the 4.0.3 firmware file. Its the same process it will auto install you need to do it this way as the 4.1.1 disables the recovery options.

    Try formatting sdcard to FAT32, make sure it is charged atleast 50% and not plugged in to anything, also try ONLY putting the update.zip/patch.zip/factory_update_param.aml on sdcard.

    Right heres somethings to try -

    1 Make sure tablet is charged and not connected to PC, run the USB-burning tool, then, press and hold the Home key and connect the tablet to the USB port, when connected press the power button and quickly, count 1, 2, 3, then release the both keys.

    Try it a few times if nothing then try -

    2[FONT=Microsoft yahei, 微软雅黑] P[/FONT]ress and hold the Home key and poke the reset hole then press Power key repeatedly.

    Or -

    3 Poke the reset hole, short press HOME + POWER keys a few times, or long press HOME + POWER keys repeatedly.
