Micromax E313 gyroscope not working after lollipop 5.1

I flashed the official lollipop update via sp flash tool.But when i checked the sensors in cpu z ,the gyro is not working along with the 3 derived sesnors-linear accleration,rotation vector and gravity. Anyhow can i make them work? maybe flashing the sensors' file from the kitkat os? any ideas

2015 phone without gyroscope? Disastrous

I can not beleive it.

sensors (acceleration gyroscope orientation etc) issues, nv data dump request

Hello,
i got a D802 phone which apparently has some sensors disabled in some way. When apps try to use them (so the system see them as existent) they fail or crash.
here some example log:

-Orientation:

Code:

---

W/OrientationEventListener( 957): Cannot detect sensors. Invalid disable

-Calibration:

I followed a lot of paths to find a solution, different distributions and full revert to all available stock versions. no way.
As my last trial I want to try to compare my NV data with a working one to search for some misconfigured parameter.
I found a great guide on how to access and extract all NV parameters and save to a text file, here:
http://www.droidviews.com/how-to-bac...imei-on-lg-g2/
As you can see, the guide is for changing IMEI, but the application permit to dump all parameters to a file.
I ask some good man to send me his dump. or i can send mine and get the differences. Because this file contains sensitive data, they should be removed (IMEI, S/N, MAC) even if i am not interested in stealing ids!

I have a D802 32GB.

thank you to everyone, hope to receive some useful feedback!.
