My Time here is to fix YOUR FAULTS!! YOU SEND A WRONG FIRMWARE. I spent week over week to fix YOUR PROBLEMS: SEND THE RED BUTTON FIRMWARE FROM a Hi9 Plus Tablet Android 8.0 with RED BUTTON - QUICKLY - it is new and look my reports for the problem I wrote to you any times, with no answers and and wrong firmware. The result is a splitted Screen/Display. There are also more than 3 people with same problem. AND YOU DO NOTHING FOR YOUR CUSTOMERS!!!
Chuwi customer care is nonexistent. This forum is for helping each other to solve problems. I suggest you to try to find a good version of firmware and someone that is enough skilled to flash it.
Not only customer care, but warranty also.
We learn from our mistakes.
In my country we tell “who spend less, spend more”.
OH YES YOU ARE RIGHT!!!
There is a thread with all rom and flash method for your tablet.
But it seems they give you the correct firmware
