Yes, uart_boot -p COM1 -r -f firmware_rec.bin followed by uart_boot -p COM1 -r -d firmware_dump.bin results in a firmware_dump.bin file which is completely different from firmware_rec.bin > You need to release the LCD lines for a normal start.

If I start with LCD lines released, I get three short blinks of the red light and then nothing happens.
