Hello,  
I have a T300 printer with firmware version 1.35. I followed the video to update it to 1.52.

Unfortunately, I get an error message when I start the printer!

A photo of the error is attached.

I have a copy of the MKS memory card with firmware version 1.35, and I get the same error when I power it on.  
Please suggest a troubleshooting solution.  
Do I need to replace the card?

Sincerely, Francis

Can you post a link to the video you followed?

I’m not familiar with the T300. Does it have a HDMI output? Linux errors would show on a HDMI display.

Did you put BOTH files on your USB drive? Maybe the screen didn’t update.

Yes, I did integrate both files for the firmware update. I followed the instructions in the SOVOL video, but to no avail! I get a different image after a few minutes of operation. The problem is complicated; I’m waiting for a response from SOVOL…
