I contacted info@fxtec.com and their response was I came here for help and I'm really speechless, what product is this selling? Now my phone has been flashed with the official firmware using 9008, and after turning on the phone, the screen will go black and enter 900E mode after waiting for 10 seconds. I have re-flashed the phone dozens of times, and the situation is the same. It is the same whether it is firmware with or without GMS.
