Good morning,
My Sovol SV04 now won’t boot, the progress bar stays at zero and the right hotend heats up constantly. I tried reinstalling the firmware, but there was only progress in the DWIN_SET on the screen, the firmware has no progress.
Can anyone help?
Hello,
Could you explain exactly what happened when you updated the screen firmware?
Is there something on the screen?
Normally, when everything is correct, there’s just “End” that appears on the screen.
In addition, you should also update the motherboard firmware. The two work together.
I have already changed the power supply, although the voltage is ok.
Before updating the firmware, the progress bar was already at zero.
Does anyone know of points where voltages can be measured to detect errors?
Did you flash both files, one for the printer & one for the screen…??

The 1st video is about flashing.
the printer is stuck on the bar, to fix it I tried to update both firmwares but the mainboard firmware remains stuck.
I need to know if there is a way to check where the problem is before having to buy another motherboard
One way to know if the motherboard is dead may be to flash it with the last firmware.
My 2 cents:
- Ensure that firmware & display software are matching.
- Ensure that the SD-card with the new firmware is formatted properly & not write protected.
- A successful update will be indicated by a changed file name of the firmware installation file from “firmware.bin” to “firmware.CUR”. In that case at least the MPU & its seven pins that drive the SD-card interface on your motherboard are still alive…
Here you’ll find a documentation of all SV04 pins & connections on the motherboard. Checking out for +5V & +3.3V should help. Additionally, you could connect your SV04 to a PC via USB-cable. This will bring sufficient power to boot up motherboard & run the display.
Good luck!
