For all users, please take care with this update ... A6 !!!
As i writed above, i got a phone bricked/locked after flash of this ROM ...
The rollback to previous version give me fatal/error message and the screen phone was responding very bad (active touch point about to 5 cm from my finger on the screen ?)
I've tryed many operations but nothing worked and i had to format completly the device ... so IMEI lost !
I flash back again to old version with glove mode inside and i navigate with USB OTG mouse for disable the glove mode.
After that the touchscreen problem was solved !!!
I flash again to 20170708 version A7 and all seems OK exept IMEIL lost.
I've repeared the IMEIL with the tutorial from this forum.
Now i have to reinstall all my apps and configuration ...
Many many hours spend for this stupid update and because very bad Blackview informations as usual.
They was not able to solve Nougat 7 problems and they try to install Android 6 on our phones without saying the true.
