Surface pro 5 SAM firmware downgrade ?

Hi Guys,

My Surface Pro 5 SAM Firmware is locked on a strange 956.30.395.0 version for a few months now…

The last released version is 239.2852.257 but my Surface doesn’t want to update. I presume it’s a “downgrade” version lock…

I got the last release .bin file, and I now need the tool and command line to force update the SAM Firmware.

Can someone help me ?

Thanks a lot.

Franck
