Hello,
a while ago I had an accident and had to replace several parts of my X2 Pro.
After I replaced the screen, the phone was booting properly. Fingerprint sensor didn't seem to work though.
I was running LOS 18.1 at that point. After upgrading to a newer LOS 18.1 version, the fingerprint sensor itself doesn't seem to be recognized anymore.
In `Settings -> Security` there is not more option to set up the fingerprints.
This has been the same for multiple ROMs. LOS 19, VoltageOS. Upgrading to RUI 2.0 firmware also didn't help. Lastly I installed the RUI 2.0 ROM, which also didn't lead to success.
By now I also replaced the fingerprint sensor itself, didn't change anything.
I'm a bit clueless, the only option that I could see working is to have a valid persist.img, where apparently the sensor information is saved. Could someone share this one? I'm also open to other ideas.

Hi,
i flashed my Pro and unfortunately wiped the persist partition. After booting everything worked fine except the proximity sensor. I searched the internet and found a solution to flash the persist_1.img. After flashing the persist_1.img the Pro crashed again and again with the blue LED on. The only way to use it was wiping the persist partition and reinstalling, but now i have no proximity sensor.
Is there any solution to get my proximity sensor back?
Thanks!
Edit: Unfortunately i am not allowed to post links...
Solved. I flashed 1.9 with qfil and after that installed aicp.
Thats the short Version, it took me 5 hours at least...
I'll try to keep this as brief as possible. Yesterday I flashed LineageOS 16 + GAPPS on my MI 8 which at that time was running MIUI 10 Global without any issues. However, after flashing Lineage my camera started acting up even though everything else worked like a charm. Everytime I tried to open my camera app, I would get a message saying "The camera device encountered a fatal error" which I could report or dismiss. Both resulted in the app crashing to my home screen after which I repeated this process 3 times, but the problem remained. Someone mentioned that the GCAM app that I was running was designed for Pixel phones and wouldn't work. I used TWRP to delete CameraGoogleLegacy which worked. I then installed a camera app but again the camera would give a black image (front and back). I then repeated this process, but I tried installing the Pixel Experience ROM this time instead of Lineage. Again everything worked flawlessly, except the camera.
Then someone asked if I flashed the correct global firmware & vendor before flashing Lineage. I wasn't too sure, so I decided to flash MIUI 10 global 10.2.3.0 again. Much to my surprise, the stock Xiaomi camera app now doesn't work anymore either, nor does the Gcam port I was just using yesterday on the same ROM.
Any help would be greatly appreciated
Thanks!
Hi,
I'm hoping someone out there can maybe help me with this please?
I have an Honor 9 Lite (LLD-L31C432) & recently the camera & flashlight stopped working. I've tried a number of other camera apps (the P20 ported camera, various google cams etc) but none work - all either open to a black screen & shut down immediately or else just say the app has crashed, etc.
The phone is bootloader unlocked and was on stock rom (LLD-GRP2-OVS-9.1.0.121). A few months ago I switched to Openkirin's Resurrection Remix OS 7.0.1 Beta 1 ROM & all worked ok (I had the stock camera, a Google Cam version and the P20 camera all working), but due to bluetooth problems I tried the Openkirin AOSP 10 Preview 1 ROM. Had a few problems with this one so tried to return to the stock ROM and had a lot of trouble getting it working again (bootloops, etc).
Eventually got the stock firmware back on but then noticed that the camera & flash no longer worked. Since then I've returned to both the Resurrection Remix ROM and the AOSP 10 Preview 1 (& Preview 2) ROMs but the problem still remains. Is it possible that I've broken the camera when fastboot flashing or using TWRP? I 'went around in circles' so much whilst trying to get back to stock that I can't remember ever step I tried, but it would seem a bit of a coincidence if the hardware failed just around the time of me having issues returning to stock ROM.
Also, If I was to relock the bootloader is it possible to tell that it has been unlocked in the past? It was purchased May 2018 so would still be in the 2yr warranty period but I wondered if Huawei could tell it had been unlocked in the past (I also read somewhere that the warranty is invalidated just by registering to get an unlock code, even if you never actually used it? - not sure how true this is!)
Cheers!

Hi, I broke the display, bought a new one on aliexpress.
Installation succeeded. The display worked.
The phone asked for an update (Some version of Android 9, probably the penultimate before Android 10), which I did. After booting, but did not working touch screen ..
I did the factory settings, but that didn't help.
I didn't deal with the phone for some time, I thought that another system update would fix the bug.
Yesterday the phone got an update to Android 10, I installed it here, made the factory settings. But the touch screen still doesn't work. (I control the telephone via the OTG adapter)
I read how to do a downgrade, but by doing an update on Android 10, I about closed the option that is described here . https://forum.xda-developers.com/nokia-7-plus/how-to/finally-downgrade-phone-official-t3849437
I read a lot of discussions and came to the conclusion that I probably bought the wrong display.
Or is there a solution? Downgrade system? Upload another touch panel firmware?
Now this is on the phone Touch panel firmware version: 07 Goodix-V1.017.20.
I attach a photo display, it might help something.
Is there any way to identify my touch problem?
Thank you for any help
Hi, since i've updated to ArrowOS 11, i have no magnetic sensor / Compass detected with any app and usually error message about it.
I've tried to downgrade to Android 10, same problem, and even with QFIL to restore ZUI, problem is still here !
Any idea ?
