I flashed my LCD screen with the V1E firmware.
It boots up and works. But after reset it tries to install something again, then says “illegal app”
Before this error I can home x and y on the LCD. But after it shows up I have to reflash TFT firmware. Then cycle repeats
After it’s flashed I can see its used BIGTREE_GD_TFT35_V3.0_B1.27.x.CUR
as that has changed to .CUR
Staying in Non-Marlin mode seems to have no issues.
Do you still have the SD card in after reboot? If so try a reboot without the SD card in the screen and see if you still have issues with TFT mode
