Models covered
LUBA 2
Rolling back from
1.15.21.1
Target version
previous release (not yet confirmed — see note below)
Last verified

Before you start: confirm your mower's current firmware version and note it down. If this rollback doesn't go as planned, you'll want that number to ask for help.

What changed in this release

Released 27 May 2026. Improved the live camera feed resolution.

What owners have reported

Multiple owners on roboter-forum.com report the live camera feed stopped working over SIM/4G on this version — it still works fine over Wi-Fi. If your mower relies on a cellular connection for remote monitoring, this is the regression to check for before you decide whether to roll back.

Rollback procedure

Follow the general Android or iOS rollback procedure, targeting the release immediately prior to 1.15.21.1.

Exact prior build not yet confirmed. Mammotion's own KB shows a LUBA 2 release dated 25 May 2026, just two days before 1.15.21.1 — very close to it, and its version string wasn't captured in our research pass. The last version number we do have confirmed is V1.11.511.631 (16 April 2025), but that's over a year earlier and there was very likely at least one release in between. Check the official LUBA 2 release notes directly for the 25 May 2026 entry before picking a target build — don't assume it's V1.11.511.631.
Version numbers on LUBA 2 don't increase in a simple straight line across releases (a jump like 1.11.511.631 → 1.15.21.1 → 1.30.29.8 suggests the numbering scheme itself was restructured) — always confirm the exact target build against the official release notes before flashing, rather than assuming "previous" means "lower number."
