I flashed phone with wrong firmware, after that I flash it with BV8000Pro_blackview_20170718, and everything is ok, but touchscreen loose calibration, there is an inversion along the X and Y axes. Help me please to calibrate touchscreen.

Did you perform a factory reset after flashing the new firmware?

Of course, I did it first. I even did full formatting. Unfortunately the core of that firmware was patched my touchscreen. I tried all the available methods to return the calibration, but none of the firmware returns the touchscreen settings. Need either a kernel with support for calibration of the touchscreen, or a program for flashing the touchscreen from the manufacturer.

Did you try also the Oreo firmware?

Yes, i try every firmvare, including oreo. Unfotunatly it does not help.

I'd try to replace the LCD screen unit with another one.... or contact the seller to have the phone replaced under warranty. It looks more like an hardware fault than a software one.
