    WM8650 Mid green led vibrate 7" tablet

    Need factory firmware or touchscreen driver for a WM8650

    The tablet worked out of the box, but shut down during an App installation and then wouldn't boot up. I flashed a Vestinious M009s ROM and got it working again, but with no touchscreen and a faulty wifi. Basically now I have a semi-working tablet: wifi scanning works but it won't connect, and the touchscreen does not work at all.

    Does anyone have a factory standard firmware / ROM they can let me have? It was exactly like the one in this thread: VIA WM8650 Hardware Information

    Any ideas about the touchscreen? I can live without wifi if I have to, but no touchscreen makes it useless for much.

    Here are all the details I can get out of my tablet:

    everything else was generic or unknown.

    It has a green led (red on charging).
    It vibrates on turning on.


    Now for the photographs.


















    Thanks for any help.

    Paul.

    Tried this one, and I just tried it again to be sure.
    Flashes fine but then boots up to the "uberdroid" message and then hangs there forever (I waited 30 minutes then called it a day).

    So far I've tried Vestinious 1.1.6, m70007t, and viapad 1.1.6 (only 1.5 build works).

    I'm running out of ideas.

    Paul.

    Maybe it's just me, but they all seem to be the same file. Anyway, downloaded, flashed and they work, but no touchscreen. I'm beginning to wonder if my touchscreen is broken. I'm in contact with the seller, lets see what he suggests.

    Hi Coresect,
    As far as I know, there're 2 different versions of 8650 tablets (even though they look exactly the same) using different touchscreen decoder chips, namely vt1603 & uor615x. Hence I suggest one thing you can try is to download the ROM from HcH'z TechKnow [www.HcH.net.tc] - Login, extract it to a SD card, and then make the following changes:

    1. file FirmwareInstall/packages/fs_patch/root_patch/system/default.prop:
    find the line "ro.wmt.touchpannel=0" and change it to,
    ro.wmt.touchpannel=1

    2. file FirmwareInstall/env/uboot_env_head,
    for the 2 lines:
    setenv touchcodec vt1603 and
    setenv wmt.io.touch 1:vt1603:2:800:480
    change them to,
    setenv touchcodec uor615x and
    setenv wmt.io.touch 1:uor615x:0:800:480

    Then make the flashing as usual.

    My 8" 8650 got the same problem as yours after flashing the ROM ... it booted up but touchscreen didn't work. It works after making the above changes. Of course I also need to change all the '480's to '600's due to resolution being 800x600 for a 8" tablet, which is not applicable to your 7" case.

    Update (of sorts): The seller offered to swap the tablet, which I'm happier with as I was beginning to wonder if the touchscreen wasn't in fact defective (I'd read in another thread that several tablet-owners had this problem). So now I'll be waiting a couple of weeks (hoping the seller is honest or I'll be opening an E-Bay dispute I guess). When (if) the tablet turns up, is there a way I can back-up the firmware in it? That way I'll feel safer and I could supply it to you guys as well.

    Thanks for the help,

    Paul.
