Huawei sometimes requires incremental updates. If your device is on EMUI 10 and you try to jump directly to EMUI 12 (skipping 11), the group version identifiers may have changed so drastically that HiSuite Proxy cannot reconcile the difference.
Reinstall the proxy/agent
The error occurs when the you have selected in HiSuite Proxy doesn't align with the Base/Cust/Preload requirements that your specific device model expects. HiSuite performs a "handshake" check before starting the install; if the version strings in the Proxy don't match the internal logic of the firmware package, it rejects the update to prevent a "cross-flash" that could break your phone. Common Causes
This error stops the installation process dead in its tracks, often after downloading the firmware packages. For many users, it signals a dead end. But in reality, it is a solvable compatibility issue between the firmware files you selected and the HiSuite Proxy tool. group version not match hisuite proxy
Resolving the "group version not match HiSuite proxy" error involves ensuring that both HiSuite on your computer and HiSuite Proxy on your device are compatible and up to date. Here are steps to resolve the issue:

The specific phrasing "Group version not match" suggests a protocol-level discrepancy where the client and the proxy agent attempt to negotiate a connection session, but the version identifiers for the specific "group" (likely a functional module or service handler) are asynchronous.
Modifying firmware and using third-party tools voids warranty and may permanently damage the device. The author assumes no liability.
This is the most common cause. You may have found a Base firmware package online and combined it with Cust and Preload files from different builds or regions. For example, using a European (C432) Cust package with an Asia-Pacific (C636) Preload package will almost certainly cause a version mismatch.
