Sorry it took so long to respond, I was at my limit of 20 posts and was locked out, plus i had to go to work.
If you are comfortable playing with imaging the emmc I recommend you use the image found here:

Get the klipad 100% up to date and then use it to “make” a new bin file. Also if you turn the printer on it’s side there are LEDs on the board that will tell you if the board took the update. I don’t have the info on the blink sequence but I’m sure you can find them.

@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.
AND
Partitioning the SD-card
Use these steps only if your card is bigger than 32GB.
For smaller cards follow the SD-card formatting steps.
- Press +R key combination, enter “diskmgmt.msc” and press .
- Locate the SD-card, right click it in the lower pane and select “delete volume”:
- Right click the lower pane again and select “create new volume”:
- Press “Next” on the welcome screen:
- Set the volume size to 8192 MB (allowed sizes are 2048 to 32767):
- Make sure to use a drive-letter that is not in use e.g. by a network drive:
- Make sure to set sector size to “4096” and filesystem is “FAT32” (other options will not work):
- Select “next” in the confirmation dialogue:
- Finally, the new partition will look like this:

OK that solved my problem, even though i was using only a 2GB sd card, changing the allocation unit size to 4096 worked and it finally flashed. Thanks for the tip, i cant believe such a simple thing was keeping me form flashing the firmware.
