I was running an Ender 3 Pro with the 4.2.7 board and a BLTouch. I had been running test and calibration prints for a few hours. I started a print and 2/3 of the way through the ABL (5x5 grid) it stopped and the display went blue. I tried multiple times to flash the firmware and even went back to a few last known good BIN files. Still no change. I ordered and installed a BigTreeTech SKR E3 RRF V1.1 board, compiled the firmware and at start up I am still getting the blue screen of death. The stock display on my E3P does not have an SD slot to reflash the display firmware and I am at a loss as to what to do next.
Any suggestions?
Thanks
