NXT-L29C432B192 to adjourn him/it to more B581 roots.

[pegasoc]

Hi, I had the Mate 8 adjourned to the version NXT-L29C432B581 but after having made some country house trying to install some ROM I have made the roolback following the guide of the assistance Huawei and I have brought him to the version original NXT-L29C432B192 with decontrolled bootloder.
I have tried to look for the updating through OTA but nothing doesn't find me.

Could someone point out me the footsteps to follow (in Italian) for B581 to install the updating and to get the root?

Thanks.
