No rollback after upgrade: Huawei (华为) Mate 80 and 40+ models move to HarmonyOS (鸿蒙) 6.0.0.328 public beta

What happened

It has been reported that, according to Chinese tech site IT之家 (IT Home), Huawei (华为) has opened a public beta of HarmonyOS (鸿蒙) 6.0.0.328 for more than 40 models, including the Mate 80 (and selected lines such as nova 14, Mate X5, MatePad Pro 13.2‑inch 2023 and WATCH 5). The recruitment is being run through Huawei’s “Fans Beta” (花粉 Beta) program and some devices were already invited earlier for closed sign‑ups; this move expands access into a wider public test.

How to join and rollout details

Users can sign up via Settings → Software update → ··· → Upgrade early adopter → Choose version upgrade. It has been reported that devices already running 6.0.0.328 do not need to re‑enroll; Huawei will push subsequent builds in batches to devices on that version. If a device hasn’t received the build yet, users are asked to wait for staged rollouts rather than repeatedly enrolling.

Downgrade warning

Huawei warns that 6.0.0.328 is an iterative build of HarmonyOS 6 and does not support rollback to earlier HarmonyOS 6 builds — once upgraded, you cannot easily revert. That makes this a higher‑stakes beta than a routine incremental update; users should back up important data and weigh the risks before opting in.

Why this matters

HarmonyOS is Huawei’s homegrown operating system developed after restrictions on access to some Western services and components, and this broader beta underscores Huawei’s continued push to mature its software stack in the face of trade and technology pressures. For Western readers: think of this as Huawei steadily treating HarmonyOS as a mainstream platform across phones, tablets and watches — with the usual caveat that staged rollouts, compatibility quirks and regional differences can affect the upgrade experience.
