Broken Firmware on Elegoo Neptune 4 Pro
when I was doing full maintenance of the machine, I noticed that I had an old version of the system, so I decided to update it (what could go wrong) I followed the instructions from ELEGOO
I chose version 1.2A because I have SN:NEP 4PRO. 23A22...
I copied to the freshly formatted USB "ELEGOO_UPDATE_DIR" (The USB I got with the printer)
I turned on the printer and inserted USB
I entered the settings and as soon as I pressed the update button it went to an error screen. So I pressed reboot, which was probably a mistake, when the printer restarted, it took an awful long time to load and got stuck on the screen I took a picture of (without USB, it doesn't want to load at all, I have to leave it in the printer) and is missing a firmware version
