Vibration stopped working suddenly Redmi Note 4

[Naagraj]

Hi guys

My mido vibration stopped working a week back abruptly. I didn't flash anything new back then.

Tried diagnosing it with change of vibration motor (with a technician) as well but the new one didn't work either. He did attempt a temporary replacement of its underlying chip as well but again it didn't resolve the issue.
Attempted clean reflash RR. Then clean reflashed Havoc 2.9 build as well.
After reflash in both the builds, didn't install Magisk (just to be sure some version could have been conflicting with the motor may be)...No solution
Attempted firmware upgrade to notably stable versions 10.2.3 and then downgraded to 9.6.3 as well. No solution still....

Could anyone advise what I could attempt next..?

Current environment: Havoc 2.9
No magisk installed as of now.


Nothing works.
Magisk 20.1 was installed but removed now... Still doesn't work...
Please help.

I don't really know what might be the issue , but I can suggest you to flash stock miui rom to see if it works there.
Don't forget to backup modem and efs partitions in case anything goes wrong with IMEI numbers. I hope that solves it.

That could be a little tricky for me since I haven't attempted to go back to MIUI again. Could you point me to a guide or so?

First take a backup of EFS Am& modem partitions from recovery.
Wipe data, cache, dalvik & system. Flash miui rom, format data and flash orange fox recovery again. Boot into system.
That's it.

Is orange fox recovery necessary? I don't know.
I an currently using twrp 3.3.1.0

Will that work?

Furthermore just to tell
Vibration doesn't work even in twrp (which actually is very strong in twrp navigation generally)
Could this hint a hardware malfunction?

Also, i did see the efs partition but not modem one....

Should work, orangefox has aggressive stock recovery deactivation which isn't available in twrp I guess.
btw quote or mention me as I can't get any notification if you don't.

Have already told you pal, try flashing miui and see if it works.
Modem partition should be in orangefox. I can't confirm as I don't have the device anymore.
