Hello everyone. I have a problem, I changed the touch screen of my m9 pipo (normal, of double nand) and I installed the rom Rileyrom, and my problem is this:
Rileyrom install normal, touch all good except in the X axis (with the tablet horizontally, the right is left and vice versa), the up and down works fine
If I install the modified kernel, the tablet not start, has bootloop.
With an official rom, the touch screen does not work (imagine that will be subject of the drivers...).
Kasty-rom with pipo-m9 happens to me as with the Riley, right is left and vice versa, the up and down works fine.
Someone I can invest the X axis of the kernel function properly for me?
As I can fix this problem?
I managed to decompile, and recompile the kernel, with the ImgRePackerRK program, but can not I edit the file .unkrnl to reverse the axis X.
Can anybody help me?
Sorry for my English translator ...
Thanks for advance!!
I tried to change the internal partitions because by default only 1GB is available for apps, this failed horrible with the provided app (HK Rom Editor) and caused a bootloop.
Afterwards I re-flashed the phone with firmwares which I found on Needrom, that worked fine but the touchscreen is totally misaligned doesn't matter which one I use. If I press for example the top part the phone thinks that I'm touching the middle, it does work fine its just totally wrong calibrated. I can't check if anything else isn't working.
Model: THL 4440, 4GB
Android: 4.2.2
Has someone any idea how I can fix this issue? Do I need a different stock firmware?
Someone told me that I deleted/overwrote my touchscreen calibration files, is there any way how I can identify the chip or get proper files for the THL 4400?

Fix for getting back your sensors and Find My Device ErrorThe Problem that i have faced.. I have unlocked my bootloader after updating my device to MIUI 11 , and flashed Paranoid Android Quartz Alpha 2 which was then based on android 10
By then my sensors are working fine. After i have flashed Xiaomi EU based on android 10 and due to some reasons i have flashed back to stock using Xiaomi Flash tool. I used to flash roms toooo often whenever i want to have to use some particular feature of that rom (That is what makes each rom unique Right!)
Suddenly on Xiaomi EU, i have noticed my gyroscope not working in PUBG also my compass stopped working , even proximity sensor failed.
Eventually i used to get an error toast showing "Find my device is corrupted your device is unsafe now"
Which i have ignored initially and realized that my persist partition got corrupted..
.
.
.
Then i have googled about my issue , referred a hell lot of threads, and came up with a working solution..
***Solution***Procedure :
1. Download the latest Fastboot rom of our device from here.
2.Extract the downloaded package and navigate to images folder.
3.There you can find the persist.img file of your device.
4.Copy the file to your internal storage.
5.Reboot your device to TWRP and goto advanced/terminal
6.On the interface, type the following command.
Code:
simg2img /sdcard/persist.img /sdcard/persist_EXT4.img
7.If your code returns error like "Invalid sparse file format at header magic" as in my case then continue with the second line of code
Code:
dd if=/sdcard/persist.img of=/dev/block/bootdevice/by-name/persist
8.Else continue with this code
Code:
dd if=/sdcard/persist_EXT4.img of=/dev/block/bootdevice/by-name/persist
9.Simply reboot to system
10.Problem solved ,Happy Face, Back to josh......
NOTE: You may notice strange behaviour of the popup camera on the first boot. As in my case it automatically opens and closes even without operating it.
with an error message showing "Cannot close front camera" which will be automatically fixed by itself by pressing "Caliberate" button which pops after two to three camera hiccups.
Thanks mate. Worked like a charm.
Here's the link to the persist.img file extracted from the Global Version "davinci_global_images_V11.0.1.0.PFJMIXM_20191028.0000.00_9.0_global_156b6de73d"

Cheers.
This will lose widevine L1.
Hey man, is this for Android 10 or 9 ? I am at MIUI 11.
Thanks! This also works in mi 8 se (with the correct persist image).
Does this work on Redmi note 7 pro
It gives me an error writing the last line
"dd if=/sdcard/persist_EXT4.img of=/dev/block/bootdevice/by-name/persist"
throws me this result "No such file"
Excelent,work too in my Mi 9,thank you.
Thanks for the tutorial. I followed this because my gyroscope isn't working properly (it orientates in wrong directions, goes into portrait when holding phone landscape i.e.).
I still have issues with my gyroscope after following your tutorial, do you have another idea what I could do to fix this. My phone is a Mi Mix 3 5G.
Thanks in advance!
Can someone please share their persist.img from their device with working sensors? Someone who has not flashed a new persist.img before please? I flashed the persist from the latest fastboot ROM but all sensor calibration values are 0 and gyro calibration fails. So my gyro is still spinning.
Good work!!!
Thank you it worked fine!!!!
Same,Can help?
Auto-brightness and rotating work again thanks ! But front camera still don't work . Any Ideas ?
Works for me too. Thanks
Works on raphael too!
my proximity sensor and light sensor work a moment and stop again I have to restart the phone so that it works again
i have been searching for this solution for past 17 days as my screen used to rotate only after boot ,but later rotation doesnt seem to work until i found this guide ,it works and works amazing
Thanks for the helpful guide
It's working fine on my Mi Max 1 Helium.
But sometimes the rotate sensor not working again, so i flash it again through TWRP.
Any solution to get permanent fix without flash the whole firmware, please?

Hello, Any way to get it back?
Good day all. I have tried many of the roms for our one plus 7t pro and It seems all my sensors are broken including the fingerprint scanning where the fingerprint shows up but won't go away until I reboot and nothing happens when I use it aswell.
I think this has something to do with the Persist.img but not sure how to fix it.? Any help would be greatly appreciated.
