@sovol3d I have the same issue and I am unable to fix it despite numerous attempts… I received the printer yesterday, could print a benchy, then followed the steps to update the firmware. Only blue screen lights up now.
I sent you an email with the details to info@sovol3d.com along with the order number.
Let me know if any other troubleshooting steps…
[UPDATE]
I managed to fix it today. I spent a lot of time in forums, with some mentioning non sensical things like making the firmware file executable, etc.
In case this helps someone:
- Use a small 8GB SD card
- Format the card with FAT32 and make sure you set the sector size to 4096 bytes (or ‘4K’) (->This is critical, many cards come formatted with 512b sector size)
- copy only one firmware (bin file) and rename it with a short simple name that was not used before for flashing.
I tried with many sd cards, formatting them from Mac os, Ubuntu and Windows without luck until I found about the sector size requirement. Then it worked right away.
