WM8650: Factory Firmware or Touchscreen Driver

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.

Hi,

I maked a new firmware with HoneyCombMOD Uberoid for WM8650 devices v1.3.0 and Original Fake with your instrutions

But I do not have access to the taskbar horizontally, only vertically

It has some configuration that I can do to fix this error?

are there any other decoder chips aside from vt1603 and uor615x?

can anyone show the syntax and parameters of the setenv wmt.io.touch and setenv touchdec?

i am trying to make to work my TS and had done a lot of combination ROM but none of them work.

thanks!

Hey I think your problem is solved, Just go to on this Topic on HCH forum and download ROM
HcH'z TechKnow [[url]www.HcH.net.tc] - View topic - Problems solved wm8650 7" (Touchscreen + Market + audio)[/URL]


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: http://www.androidtablets.net/forum/wondermedia-based/10766-via-wm8650-hardware-information.html

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:

WonderMedia WM8650
