No Sensors Working : Proximity, Gyro, Magnetic Field, Accelerate. - Coolpad Cool1 Questions & Answers

I flashed AOSP extended Pie rom in my cool1 dual indian version. Then I decided to roll back to official stock EUI 5.8.017S. Now I am facing few errors like; when I try to add a fingerprint it shows error as, 'Can't store fingerprint. Delete the existing one first'. I don't have any previous fingerprints on the device. I did factory reset but no avail. Also, the proximity sensor is not working. Magnetic field and auto rotate are also not working.
I looked for a solution in 4pda forum(I can't share the link as I am new user). They had the solution but the files were not accessible now(maybe removed).
Can someone help me in this matter? If possible, please share the persist section for sensors.

Hello, Had a question regarding the FP and enableing it

Hello, I flashed the latest CM7 weekly which enables the FP sensor..
The menu shows it as an option under security... but the FP sensor doesnt seem to register any swiping.
I have attempted to wipe data/ cache/ and Fix permissions... However, these did not resolve my issue.
I was wondering if anyone had any advise as to what I can do next in order to enable the feature back.
I dont think that my sensor is 'broken" because it was working just fine before starting to use the CM7 roms for our phone.
Thank you for your support!!

Proximity sensor issue.

Hello. I have 2 questions for you. 1st is i flashed pacman rom to my device. After that my proximity sensor killed. I formatted my phone and flashed previous rom. Proximity still not working. I tested it with sensor tester. It says your phone not allows proximity. How can i fix it?
And second question is, how can i back to stock system on g7? I cant install system with dload. Thank you all!

Fingerprint sensor freaked out on CM12.1

Hi.
I've been looking for similar problem here but I've found nothing.
Here's my situation.
Stock rom
Unlocked bootloader, changed recovery to TWRP
Backed up stock rom, flashed CM13
*CM13 apps are crappy* Backed up CM13 and restored stock rom.
Current status: fingerprint sensor freaks out. I've came up to this in camera app as soon as it started to take billions of selfies (idiotic feature of taking picture by fingerprint sensor). Then checked if I can set finger pattern - not at all, ZUK started to take thousands of patterns and vibrating all the time. It's hard to explain, but it seems that sensor stucks in a loop that scan fingerprint and somehow founds it (even if ZUK is lying down untouched).
Best of all is that, when I restore CM13, sensor does fine as new, so it can't be strictly hardware issue, drivers perhaps?
The fact is I don't really need fingerprint scanner and best solution would be disabling it.
Any ideas how to do this? Or what really happened and how to restore its functionality?

You can try to delete /data/system/users/0/fpdata/user.db and /data/system/0/users/settings_fingerprint.xml. Then reboot.
Another possibility is to reflash stock rom, not restore backup!
I have also been through the same situation. Restoring the COS 12.1 will freak out the Fingerprint scanner and camera issue as well. The best option is to flash the Stock ROM COS 12.1.
Happened to me aswell.
I did this:

You can't downgrade android version via backup because each Android version needs different firmware files so if you want to roll back from mm to lollipop you must flash the needed firmware files, you can do that flashing cos12.1 via twrp or fastboot.

Fingerprint enrollment problem

Hi guys,
Recently, I have installed Arrow OS 9.0 and I was unable to enroll my fingerprint (But I can use my fp sensor as home button).
Currently I have flashed stock ROM and restored IMEI. I was able to use both my SIM slots and device name shows xt1643. Again, I was not able to enroll my fingerprint. The error message reads "INTERNAL ERROR, Sorry your fingerprint can not be enrolled due to internal error". But, after rooting my device i was able to use it as home button.
Is there any thing that i have missed? Or is my fp sensor gone?

I am using Redmi Note 4 and facing same problem after flashing Aosp Extended Pie ....The fingerprint sensor wouldn't just work. As if it is dead
Tried deleting these files
Root/data/system/users/0/settings_fingerprint.xml
And
Root/data/system/users/0/fpdata/users.db
Now the files are gone and sensor is dead ....Works when Miui is flashed but dont know what is going wrong in custom Rom

Thankyou brother for the info. But even after reverting back to stock rom, my fp sensor was not working properly. Maybe some of my vendor files were messed up.

S6 Edge+ fingerprint sensor not working after stock flash.

So I flashed lineageOs 17.1 unofficial build on my phone earlier to test it out. After booting into it, I realized the fingerprint sensor wasn't working so I flashed the stock rom using odin. After boot, fingerprint sensor still didn't respond and when I try to add a print, I get an error,"make sure the home key is clean and dry, then try again.", so I used the dailer code (*#0*#) to run sensor diagnostics. The results are as seen attached. Is there anything I can do about it? The home button still works fine so I doubt its a hardware problem. If anyone has a fix for this i'd be grateful for you to share.
