I had already upgraded my firmware for my 8227L to a later firmware I found on XDA. The reason I upgraded was because I had a failed root attempt and corrupted the su binary.Now today the seller sent me the original firmware that came with the unit. I flashed the original firmware and my screen alignment is now off, please i can see the lines down the screen. When i flash the newer firmware and was hoping it would go back, but now that is the same misaligned and pix elated.

Even the android logo on boot is shifted to the right.

This is the fix, updated MCU.

my MCU now shows TS907.181110(W)
