I have one BV9500 (not Pro) phone.
And I have error is the system during refresh.
My current firmware version: BV_BV9500_V1.0_20181026_20181119-1437
The new wireless update version: BV_BV9500_V1.0_20190320_20190320-1435
The updating file is downloading successfully, automatical unziping OK.
Rebooting the phone, and the update is starting. But about at 20-25 percents the system updating is stopping and indicating only this failure message : "ERROR" .
The phone is starting automatically again, but the refresh is failed.
I have already tried the hard a reset, no SIM card, no memory card, but the updating is failed.
What is a problem, and when is new updating coming?
Radomised simprocess error reboot is frustrating every 1-2 days.
I hoped , that unfortunately this updating would have helped but I was deluded .
