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 29 April 2026. Mammotion's own changelog for 1.15.20.2303 describes improved remote-connection performance, reduced iNavi NetRTK data usage, and optimizations to thin-pole detection, docking, and open-field positioning drift.
What's been reported
The opposite of the intended improvement: after this update, the RTK antenna stopped switching modes, causing NetRTK activation to fail1. If your mower is having trouble establishing or maintaining an RTK fix after updating to this version, this is a documented match.
Rollback procedure
Follow the general Android rollback guide, targeting 1.15.6.2300 (23 March 2026) — the release immediately prior to 1.15.20.2303, per Mammotion's own KB2.
No confirmed manual downgrade path exists for the mower's own body firmware (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.
