MultiTouch Problem in Coby MID 1042-8 After Install ROM

[marvinabr]

Hi All, after installing a new rom, a problem appeared with the Multi-Touch on my Coby 1042-8.
It seems that it is upside down, pressing the right touch finds it down, left up, top-left and bottom-right. Apparently it's a mirror effect.


Watch the video below:

Reset does not work, the Coby is working perfectly, just the touch is not calibrated.


I've been looking for configuration files for a week, checked the build.prop, but I do not know what would be the line of the configuration change.


Anyone have any idea how can calibrate TochScreen?


The coby is with ICS.

Tks.

Check your build.prop for ro.sf.hwrotation=180. Try commenting out the line by placing a # in front of the line and see if that helps you out. If you DON'T have it in your build.prop, add it.

That's common when you use the wrong touch screen drivers, restore your backup and you will be fine.

It did not work, I added, tested, and tested again commented. the mirror's effect is only in touch, not in screem

My file build.prop contains no line with "ro.fs."

there is a problem... i dont have backup. I install a wrong image with livesuit, now coby is revive with stock rom. I get backup for other coby 1042 but dont work for touch screen

 

[vampirefo.]

you need to determine what touch screen driver you are using.
try these commands,

busybox dmesg | grep ft5x

or

busybox dmesg | grep goodix

also look at init.sun4i.rc
see what drivers are loading.

should be locate under

#insmod key & tp driver

 

[marvinabr]

Hi Vampire, the command busybox not locate "grep" function.

In init.sun4i.rc have two lines, one is commented:
#insmod key & tp driver
insmod /system/vendor/modules/ft5x_ts.ko
# insmod /system/vendor/modules/sun4i-keyboard.ko

change "#"?

code for busybox:

Ok you can fix it but a lot of downloading replacing files and rebooting unless you get lucky and get the correct driver the first time. You need to download every coby dump you can find, 7042, 8042, 9042, 9742, 1042. Extract the ft5x_ts.ko push it to your tablet boot into recovery factory reset reboot repeat until fixed.

Hi vampire, tanks for your help. I'll try today

ok, not so easy to find the dump files system.tgz, found some but did not work.


If they have a Coby and can help me sending the file "ft5x_ts.ko"? is in \system\vendor\modules\ft5x_ts.ko


can attach forum or at my email [email protected]

I make a dump of my coby before kill it, so I will try to restore and push the ft5x_ts.ko and will let you know if works.

Looks like I maybe in the right area here as I recently purchased a Coby MID1042 and proceeded to destroy the operating system including the recovery I have recently found an .IMG file that brought it back to life and works very well except for the fact my touch screen is whacked and very unresponsive any ideas would be appreciated .
At present I am using a USB Mouse to navigate the tablet. I used Live-suite and flashed this img file it works except for the screen I am learning fast here but not to savvy on the Dev lingo .

read through the thread.

I seen a post you made "
[h=2]Linux users, Coby 1042, root, recovery, update all without livesuite,[/h]I would like to ask if there is a program to allow me a Linux based environment on my win 7 system?
I have recently added Cygwin Terminal to my system haven't used it yet as I have a lot of reading to do first.

I don't know anything about windows, you could dual boot linux and windows or run linux from a cd or from a usb drive or from a virtual environment.

As for your touch screen problem, you will need to find the right touch screen drivers, for your tablet.

 

[rtype540]

The cygwin terminal is suppose to be a virtual Linux environment for windows it contains the kitchen android so just for educational purposes as I am unfamiliar with Linux I am gonna give it a go with your instructions on Linux users, Coby 1042, root, recovery, update all without livesuite, It is apparent that Linux is the preferred system for this type of programming. I will let you know if this works under windows as I imagine I am not the only one in this type of situation .
