    To make a long story short, I was tired last night and not paying enough attention, and I used the IUW burn tool to flash u-boot.bin as the U0 in the 2852 firmware update.

    This is very, very bad. Now I have in my possession a brick that buzzes non-stop when turned on. No button pressing combinations get around this, and I have not been able to connect via USB or to boot from SD card to recover it.

    I am hoping someone has a solution for resetting the firmware or otherwise fixing the damage I have done.

    Feeling dumb,

    Did you toss the pad yet?

    Theoretically what you are looking for maybe called JTAG. But there are some questions left:

    1. Does the pad have a JTAG interface / is it documented?
    2. It it realistic to get a cable connected to that interface?
    3. Are the instructions known which will be needed to use the JTAG interface.

    Where are you based?

    I thought jTAGS were just for the xbox 360?

    JTags are generally modifications to any device in which has support on the board for serial communications that can be used to read/write to/from a particular chip/device. You can jtag all sorts of devices, not just xbox360.

    I'm aware of Flashing from USB, it's very risky that's why I stay on flashing from SD, coz there is now way to brick by flashing from SD, because anytime I can restore it back from factory firmware by pressing the combination buttons.

    If the tab is able to charge, leave it to full charging, and try to recover it with button combination.

    see here.

    OS 2.1 Flytouch2 SuperPAD reset for reinstall the system

    or your old recovery partion.

    the one which is reached by pressing "Volume -" , "Home" and "power" altogether



    EDIT:

    30mins ago, I'm thinking to update my 2.1 Eclaire to 2.2 Froyo, I did the SDCard Update and still failed, because it will always freeze.

    So I decide to do the USB Update, and made my own Male to Male USB Cable, coz I dont have some time to go out and look for A to A USB Cable.

    [​IMG]

    I follow this guide.

    [ROM] (Flytouch 2, SuperPad, WWE10) 2.2 v2.1 #3925 - xda-developers

    And it's a Success!

    [​IMG]

    This is my screen shot before.

    [​IMG]

    First uboot doesnt have a cam feature, then I flash the uboot that has cam, and it works fine.

    After Flashing Im having this.

    After 2 reboots it's working normal.

    I had to make my own cable as well. My first attempt didn't work but my second did. Probably because I actually spliced the wires this time...

    Unfortunately when they will not respond to the IUW program they will not (likely) respond to ANYTHING... and about the only way to restore them is to get a programmed chip and swap them out.
    That, or POSSIBLY the use of the jtag port... IF IT HAS ONE. I am working on this 2nd option but have temporarily stalled out as my sight is too poor up that close to get a proper connection right now.

    JTAG is quite new in my toolkit and I have not yet made a successful interface to a device... but I have 3 machines I need to attempt it on... soon! :rolleyes:

    Hello. I have completely bricked SuperPAD III. No vibration at start up. I can charge battery only.
    Device failed to update ROM. I used IUW 1.2. I made a mistake and changed a U0.
    After a few research I've found out that there might be a chance to recover my device. This might be done with Willem Programmer. I need precise information about which microchip is responsible for U0, U-boot. I am not sure, but this might be MX-29LV800BTC-90. This is 8M-BIT
    [1Mx8/512K
    x16]
    CMOS
    SINGLE
    VOLTAGE
    3V
    ONLY
    FLASH
    MEMORY chip.
    It is TSOP-48, which means that I need also an adapter TSOP-48 (8/16bit LV) for willem programmer. This chip can be erased with willem programmer, no additional UV eraser is required.
    But main problem is that I have not original ROM for this chip.

    My android tablet is:
    Model: P1001R
    Android version: 2.3
    BUID: FRF85B

    To cut it short, there are many fake models of flytouch 3. My device is one of that. BUT, IT HAS YONESTOPTECH 101 MOTHERBOARD
    Can anyone tell me what image (u-boot) can I write to this chip using Willem Programmer?
