Update firmware in LAN-only mode, or at least without login

[ccloli]

Is your feature request related to a problem? Please describe.

There's no firmware updates in LAN-only mode, it always says it's the latest firmware, even though any normal people would say 01.03.00.00 is higher than the "latest" 01.02.00.07.

There's already a bunch of discussion about updating firmware in LAN-only mode, like:

• Bambu Studio does not report when there is a new firmware update #1580
• Firmware Update not possible in LAN mode #4026
• https://forum.bambulab.com/t/fyi-lan-only-model-no-notification-of-firmware-updates/8955
• https://forum.bambulab.com/t/remove-lan-mode-limitations/51792

If you said the LAN-only mode is not connected to the server, so the printer cannot receive OTA. But even though you've already turned off the LAN-only mode, if you don't login your account in printer, you still cannot receive OTA.

And once you logged in the printer with an account, it shows the update in Bambu Studio.

Describe the solution you'd like

• For LAN-only mode: Allow manual download & flash firmware
  • You can do this by putting the firmware in SD card, and load it from SD card.
  • Another way is to download the firmware in Bambu Studio, then transfer the firmware file to the printer in LAN.
• For updating requires login: Allow checking updates without login
  • You've already connected to the server, because it checks whether the region is valid or not, then shows the dynamic login QR code, I don't believe this can be done without Internet. So since you've already connected to the Internet, why not just check and download latest firmware.

Describe alternatives you've considered

N/A, it's already cleared.

Additional context

People DO care about privacy, not everyone likes putting everything on or through the cloud, I believe that's the reason why you introduced the LAN-only mode. So please consider improving the LAN-only mode, like the features listed in #4512 .

Yes please. Upgrading firmware should not require apps and accounts and everything that goes along with it. This is the primary reason I would not recommend a Bambu Labs printer to anyone who asks me about mine. Knowing what I know now I would not buy one.

X1E now supports offline firmware update
"The latest firmware release for the X1E implemented the offline MicroSD firmware upgrade support, for customers that wish to keep their printers offline. Our team is already working on implementing the same feature for the X1C and then, for the A1 and P1 series, in the following months"

Well now they have added the feature to P1, but you gotta do a firmware update to get it… Don’t get me wrong, I’m happy that new buyers will get to update without an account, but it sure looks like I am going to need to log in for this old 01.03.00.00 machine I have.
