Hello All,

I have successfully rooted my red magic 6 pro phone using the method described in the forum post:

I am faced with the issue of the fingerprint reader not working.

Tried fixing it by running the calibration procedure (https://forum.xda-developers.com/t/...er-print-after-loss-data-calibration.4132961/) with no success.

If anyone of you has an operational fingerprint reader in their red magic 6 pro and they would like to help me fix mine, please sent me the persists.img of your phone so I can flash it in my own and get the reader operational again.

There is another post that describes the procedure on how to extract the img from your phone from the forum:

Any assistance will be greatly appreciated.

You need your persist.img that shipped with phone. Someone elses will NOT. You have lost FP forever.

I've read for another phone that they were able to restore the functionality with the persist of another phone. I understand that the sensors are calibrated per device but it seems that the issue is more related to the security of the root rather than persist being actually corrupted.

Are you aware if I flash stock rom again if there is possibility for FP to work again?

why don't you extract it from the original ROM?
If I am not mistaken, this is a per device partition and is not included in any ROM. As I understand it, persist.img contains all the sensors calibration data for the phone.
This is why I request from someone who has the same phone to extract and share so I can have a chance to save the FP functionality in my phone.

Understood. Yes, it's not a ROM file. I may switch to this device in the next day or two. Don't mind giving you a copy of mine if you haven't got it by then..
