Hello
Well guys , I have Jiayu G6 (mtk6592) , had to flash Stock Rom , but mistakenly downloaded and flashed Jiayu S2 (mtk6592) firmware .
the phone went Dead , then i downloaded and flashed the right Firmware for G6 . now its working fine but the touch screen messed up , when i click on something it will respond somewhere els ..
Flashed the stock recovery with sp flash tool , i tried all Stock recovery available for this device and same problem , i tried Restore my TWRP Backup but the touch screen problem did not fix ..
I have the whole backup which i made before flashing the S2 firmware ( see image attached ) .. but do not know what to do ?
any idea?
i do not know if the S2 Kernel burned something on the Mainboard .. i do not know if buying new touch screen will fix it or not

so it seems there are two different variants for this model, maybe more
try flashing preloader.bin and lk.bin from your backup
was this backup made before OR after you needed to flash stock rom?
why did you need to flash stock rom in the first place?

did you try all the roms @ https://pan.baidu.com/s/1eRUK0IA >> ROM > G6 ?

hi
thx for answering me
the backup was made long time before this happens .. the phone wifi was not stable it kept disconnect so i thought reflash the stock firmware to see if it will fix it but mistakenly flashed the S2 Rom ..

i tried to flash preloader.bin and lk.bin from my backup ,but that did not fix it .. still the touch screen not responding well .. i do not know if flashing wrong firmware could Cause hardware fail ..i kinda have feeling it burns something on the IC chip for the touchscreen chip ..just not sure
thank you for the Rom link , but none of the rom Helped .. same thing .. touch not working right ..

how about flashing the entire backup you made?
unless your phone fell or something hit the screen then its still software related
unpack system.img from your backup and check build.prop for the build number using method 4 @ https://www.hovatek.com/forum/thread-16005.html
post the build number here

...

you build number is ifferent from the rest
firmware for G6W 20141121-180733 is @ https://pan.baidu.com/s/1sjjXaNz
download and flash everything, if touch still doesn't function after flashing then its now a hardware related problem

EMMANUS · 28-02-2019, 10:09 AM

Something else you can try is booting to factory mode and perform a calibration (touchscreen) test. See if all the spots you touch indicate touches.

onasre · 28-02-2019, 11:11 PM

done every thing and still no luck ... i believe its hardware fail but i do not know if its on the mainboard or the lcd part
