[Please help] Acer zest T06 touchscreen urgent help
(18-01-2017, 10:59 AM)MasterSheea Hello smart people !
Please someone can help me, please?
I have an Acer T06 that I am using just like a paperweight
I have installed the wrong twrp because the link was wrong: https://forum.xda-developers.com/and...st-3g-t3420325
After this, the touchscreen is no more working. Mouse and keyboard are no detected.
In some micro-points the touch works, but just in some moment.
Pressing and swiping repeatedly with the palm of my hand, I am even able to unlock the screen, sometimes.
Now I have the right twrp installed and I am working in adb via a modified twrp that supports adb.
- I did a test with SP flash tool --> Error: nand flash was not detected. Error: UFS was not detected.
- Factory kit test gives me this error: firmware detected failed, ctp firmware version (provide by ctp vendor): b1.
The following values are read from the tablet!!
ctp firmware version: a1
ctp driver: Himax852xes_himaxctp.
I have formatted all and reinstalled all with sp flash tool and SP MDT tool, but the touchscreen still does not work.
I have formatted all and re-installed via TWRP: the same.
I can not install apps into phone because I can not use the touchscreen.
In some micro-points the touch works, but only in some moments.
Pressing and swiping repeatedly with the palm of my hand, I am even able to unlock the screen, sometimes.
I have asked almost everywere, but nobody is able to solve this problem.
Please, there is someone able to help me, please?
Otherwise I have to resign to throw the almost new phone in the trash.
I thank you in advance to anyone will try to help me
Greetings!

I have flashed only the recovery.img with SP flash tool.
I have used the scatter file of the official firmware.
Later, since the touchscreen was no more working, I did more attempts to restore it: format bootloader, reinstall bootloader, format all the partitions and reinstall the firmware, install via TWRP recovery. I have also tried 4 different versions of TWRP recoveries compatible with this kernel.
I have reinstalled different versions of the firmware.
No luck, nothing done.
In general, the phone works very good with all the firmwares I have tried; the only problem is the touchscreen.
I hope to hear from you soon.
Greetings!

Thank you for answering me.
I think that it is a software problem.
Or I have the wrong firmware.
Or there is some file .Bin/.img missing in my firmware folder.
Or I have to change LCD driver at boot in ik.bin.
Or I have to push the driver manually into system.
Or I have to re-calibrate the touch panel.
Some version of SP MDT allows to change driver at boot, LCD driver included!
Unfortunately, I can not find a version of this program working with my scatter.
I really hope that is a software problem... Otherwise I can really trash the phone.
The new touch panel for this phone costs almost like the whole new phone.
(19-01-2017, 03:06 PM)MasterSheea Yes, I have tried all of this files, different revisions.
And the rest of the system works good; only the touchscreen is dead.
Maxpayne, I hope that you do not have right .
Otherwise I must buy a new phone.
