Ortur Laser Master 2 Pro S2 - Firmware Update - Win11

I was experiencing exactly the same problem as others on a Win11 laptop. Firmware would not update and kept falling back to old “installed” firmware. After reading multiple posts it occurred to the problem might be the file System on Win11.

I solved the issue by copying the Firmware .bin file from the unzipped download folder to a memory stick and then copying pasting (actually drag and drop) from the memory stick to the newly created USB drive that Ortur created using the 5 sec/reset button sequence.

Worked like a charm.

System:

Edition Windows 11 Home

Version 21H2

OS Build 22000.2538

Windows Feature Experience Pack 1000.22001.1000.0

FYI; during my troubleshooting steps I tried different .bin files that I found on the web, and tried doing it via MS-DOS command prompt using copy command. These did not work.

Hello Rob

Could you get a printout of the Information in the console when you type this command:
$i
Press enter

Ortur will reject the firmware if its not exactly the file format it is expecting.

Also, can you type in the full name of the firmware file you are attempting to upgrade with?

Seems to me the firmware is already latest version
$RST=* to reset firmware to defaults - if you want to be sure everything is working correctly.

It wont update any further.

Gil,
You are correct. This is after the update, before the update it was 1.87 and the $RST=* command was executed as per the instructions.

As far as I can tell everything is ok now.

Gil, I just picked up a Laser Master 2 Pro and it currently has OLF: 170 and I am having the same error 0x800701B1 when trying to update firmware to the 1.91 and its like the Ortur will close the usb driver after each error.

Hi Jess.

This is more than likely because you are attempting to install a OLM2 PRO S2 firmware (1.9x) into a S1 firmware 1.7x

You will have to inquire with Ortur for the latest OLM2 Pro S1 firmware, which should be 1.78.
