Surface Go September firmware update - firmware is older than installed 89.91.17692 < 1494442258? #9

Closed mannp closed 3 years ago

Hi there I am trying to update my Surface Go to the latest Sept firmware with fwupdmgr 1.4.6 and I am getting the above error.

I haven't updated the firmware since removing windows and installing arch linux, so I do not believe I have this firmware installed.

I wondered how I could go about debugging the issue?

Thanks in advance

Microsoft likes to randomly change the version number that is used by the UEFI to a lower one.

I had that issue too when I recently installed the latest updates, and a few times before that.

If you want you can tell fwupd to allow downgrages (fwupdmgr --allow-older or so), then it should flash fine.

I see okay, thanks for the info.

Did you install all 4 of the cab files available for your device, as without the version numbers I am unclear which ones needs updating.

Just flash all of them. fwupd will show the same error if the version number is actually the same. Once you flash them with --allow-older it will tell you that the version is already installed.

Just done exactly that and 2 gave wrong version of flash utility error and only the UEFI flashed.

I have now gone from UEFI 1.0.19 to UEFI 1.0.28 but not the latest 1.1.18.0 from September 2020, so maybe just a matter of the downloads not being available yet?

btw thanks for creating this, its great :+1:

If I get the cab files from the repack script it works fine for me with this command fwupdmgr install --allow-older out/SurfaceGo-WiFi/SurfaceGo-WiFi_ISH_3.1.0.3524.cab

I'm currently on Arch Linux

EDIT: I should add you may need to run the fwupdmgr command as root. I'm on Gnome so I got a password prompt when not using sudo or root.

Thanks @ShapeShifter499 for the further confirmation :) it worked for me with the --allow-older option and I should have closed this.
