Problem or Use Case

In https://github.com/maziggy/bambuddy/issues/520 it was raised that bambu didn't upload the offline package yet, which is true, but the assumption that they always do seems wrong. I ran into a similar problem with my P2S, which has an update available (Currently 01.00.05.00, available: 01.01.00.00,01.01.01.00,01.01.03.00). On the firmware website there's only 01.01.01.00 available. I wrote to Bambu Support and asked them what the expected timeline for the update is, to which they replied:

Firmware version 01.01.03.00 is a hotfix version, and there are no plans to release an offline package for it. The next one will likely be released around May.

It would be nice to update to intermediate releases. This would also be nice if the newest version has some known issue, but you still want to update to a version in between.

Proposed Solution

Intermediate firmware versions are available for downloading in the firmware update modal and can be downloaded to the printer independently of the newest firmware version.

Alternatives Considered

It's of course possible to manually download the firmware file and transfer it to the USB stick and then start the offline upgrade.

Yeah, but how shall I do that if Bambu Lab doesn't publish the firmware?

What I'd imagine would be a drop down with all versions that are newer than the currently installed firmware, allowing to download in this case the version 01.01.01.00 explicitely instead of the newest version.

Still don't get it. Bambu Lab has answered, that these versions are not available as offline packages?! So how should I detect them?

In this case 01.01.01.00 is available as an offline package, but not 01.01.03.00. In the firmware release history all of them are listed.

So it should list all found versions for printer model and indicate their status (available for download, not available for download)?

Yes, that would be ideal I think / would allow the upgrade to the available versions

I was going to look into this myself. The container log shows:

2026-03-04 11:35:07,992 INFO [backend.app.services.bambu_ftp] FTP connected successfully to xxx.xxx.xxx.xxx (model=P2S, prot_c=False)
2026-03-04 11:35:08,084 WARNING [backend.app.services.firmware_check] No firmware download URL available for model: P2S
2026-03-04 11:35:08,085 ERROR [backend.app.services.firmware_update] Firmware upload failed for printer 1: Failed to download firmware

So as an intermediate step, what if we could provide the URL for the firmware in the dialog?
