7 inch IPS display on 1024X600 resolution capacitive multitouch.
The original firmware was a nightmare, so slow , and full of chinese thing with no google play, quick decision -> get another firmware.
I've installed an actual version of AOKP ( I think it was the 9th version) and I used one of those comp file which was for an ainol tablet same hardware details.
After this , my big four minetes has started until a figured out the camera does not work.
I used another compatibility file, from a hyundai tablet same camera details, camera ok , but the touch chip went down and cannot get back, since that.
Ghost touches on the screen, but the normal touches are recognised as well.
Do you have any idea, how to reflash that touch driver chip?
attached files from the original firmware, maybe give some help:
And a video on y_-tube, with this watchcode: YfNZf2BgL3w or use "ICOO D70W ghost touch problem" keyword
Thanks in advance.
If you could Post an lsmod from both the Working Firmware and the Non-Working I will take a swing at answering your question...The problem is likely one compat file is installing drivers for one of Your pieces of hardware and not the other and the other compat file is istalling the driver for the other piece but not the One... confusing sounding...
But Bottom Line is If I had the Lsmod from the working Hardware and the 2 compatability files you tried I could likely alter one of the compatability files to cover All of your hardware.
Or better yet pull the Bootloader.img and the Boot.img out of your Tab and send them to me...
you can do this by opening a cmd window from a directory where you wish to store the .img files then type the following :
adb shell su -c "cat /dev/block/nandc > /mnt/sdcard/nandc-root.img" (Press enter Key)
adb pull /mnt/sdcard/nandc-root.img (Press enter Key)
That will give you the Boot.img (named nandc-root.img)
adb shell su -c "cat /dev/block/nanda > /mnt/sdcard/nanda-bootloader.img" (Press enter Key)
adb pull /mnt/sdcard/nanda-bootloader.img (Press enter Key)
That will give the bootloader.img (named nanda-bootloader.img)
send those from both your OEM Rom that is working and the Target Rom you wish to make work .... from that I can either write a compat patch for it or send back the edited ones from your Target Rom (the one you wish to work)
