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 owners have reported
An owner on roboter-forum.com reports that the mowing blade starts and then stops again after a short time, requiring the switch to be manually re-confirmed before the mower will restart. This was reported across both the 3 July 2026 (2.3.27.20) and 19 July 2026 (2.3.27.23) updates, and the owner had an open support case with Mammotion at the time of posting.
Rollback procedure
Follow the general Android rollback guide, targeting 2.3.25.19 (17 June 2026) — the release immediately prior to 2.3.27.20, per Mammotion's own KB.
This targets the mower's own body firmware, which our research has not found a confirmed manual downgrade path for (see the Android guide) — treat this version number as the target to look for via whatever path exists, not a confirmed working procedure in itself.
