    Hi all,

    I have a onda v811 and it has worked fine for the first few days. But now when I turn it on rather than having the usual boot screen a white android icon comes up and will stay on. The battery is fully charged and I have tried the reset button. Is there another way to return this tablet to factory settings? Maybe some key combination of power and home button?

    I believe it has the same buttons as the v711.

    Thanks in advance for your help.

    When the tablet is turned off, keep home button pressed.
    Now turn on tablet while still holding the home button.
    When white android figure appears, release both buttons.
    You will get into recovery mode, you can select "restore factory settings" there.

    If that fails, try flashing new firmware.

    I tried the reset with no luck.

    Do you have a link on how to flash new firmware?

    Thanks

    Download the right firmware here: ONDA

    Extract the content to the root of your sd card (since you cannot use your tablet, i suggest using a cardreader + pc or another tablet? or try to hook your tablet to the pc and hope it recognizes it)

    There should be 5-6 files now on your SD card.

    Turn on tablet while holding home button, untill white android figure appears then release.
    It should update your firmware now...

    Hi

    I have a similar problem with my onda v712. However my tab won't go into recovery/update mode after pressing home and power button so I am unable to reflash. I copied the 5 firmware files to the root of a formatted card and inserted the card after switching off the tablet. When I press home and power buttons for a while, the white android bot appears. I release the buttons when the white bot appears but nothing happens beyond that even after 30 minutes. What should I do?

    I got mine to work I flashed the latest firmware. It works most of the time but still freezes time to time. Does everyone have these problems or are there some that work fine out of the box.

    When you try your reset try this. Hold the home button down then press the power button while holding the home button. Keep holding the home button and it should go into recovery mode.

    You will need to get the 1.5.5 firmware as it flashed using the USB program, the link is below, once downloaded open the zip file and drag the usb program folder to your desktop then drag the resource zip file in to the usb program folder on desktop then run the usb program, you an change the language in top left corner, connect your tablet and hold home and power keys until the program picks it up then in the config tab choose install upgrade and select the resource zip and start the flash.

    My V811 was working fine for several months, until it stopped booting up. I had left it for charging overnight. Now I see that i am not able to boot the device up. When I press the Power button, I get the White Android Symbol for a few seconds and everythings goes off. I have tried getting into recovery mode by pressing Home Button & Power Button, again response is same. No recovery screen.

    Also, when I connect to the Charger / PC, i get the full power charged symbol.

    I am just not able to get past this stage. Has anybody faced this problem and any tips on unbricking the device.

    PS: I had downloaded the latest firmware from Onda site and upgraded the device.

    Try this
    I found this method fully working
    [​IMG] Unbrick ONDA V811 (100% working)

    Hi,
    i also faced this problem, when v7 was out & my tab was useless...
    NO wifi, No proximate sensor... :(
    i tried many methods but can't recover from that.. Same thing again happens when v8 was out... but now i know the way to recover from it... the all problem is because of flashing wrong "Kernel"
    ADB or recovery wont help...
    even the V811 not detecting in "M3 devices" or "world cup device mode"

    "The Device is HARD Bricked"

    I searched every where but there is no solution for fix.... then i tried hardware trick to recover from Hard Brick

    100% working

    first thing to do is disassemble your tab.. here ho to do this



    *you don't have to disassemble the LCD or touch Panel
    Just open up the tab

    then you have to locate flash memory chip

    [​IMG]This image has been resized. Click this bar to view the full image. The original image is sized 878x640.
    [​IMG]

    At this point you should have the device plugged in and the AML software open. Have the Windows Device Manager open in another visible window and you should also be able to see if there is a Device change in the AML command prompt looking screen.

    On the left side of the chip there are a series of pins.

    [​IMG]

    Using metal object, bridge those two pins by creating a connection between them.

    press and hold the Power and home buttons

    The device may show up in the Device Manager as an M3/M6 chip at this point and as connected to a port in the AML software. You can remove the metal object and Flash the device with compatible firmware.

    if not work, cut the battery red wire and do the above steps
    when flash complete disconnect the TABLET and reconnect the red wire.


    Enjoy your TABLET fully working..

    Happy Unbricking
