This guide is for educational purposes. Modifying system software or using proxy tools to manipulate updates carries a risk of bricking your device. Proceed at your own risk.
If all else fails, remember that HiSuite Proxy is not the only path. Direct fastboot flashing, DLOAD method, or professional box tools (Octopus, Medusa) offer alternatives. Always ensure you have a full backup before attempting cross-version flashes.
To provide more specific steps, I'll need a few more details: Your and current Build Number The Target Version you are trying to install The Version Number of the HiSuite client you're using

Re-download the firmware files (sometimes they are corrupt).
If you are reading this, you have likely stared at a frustrating red error message in the HiSuite Proxy tool: (sometimes written as "Group version does not match" or "Group version mismatch"). You clicked "Setup" or tried to roll back (downgrade) or upgrade your Huawei/Honor device, only to be met with this cryptic roadblock.
For Huawei and Honor device enthusiasts, has become an indispensable tool. It allows users to bypass official over-the-air (OTA) restrictions, roll back to older firmware (downgrade), or force-install specific builds for unbricking or repurposing devices. However, as Huawei tightens its firmware delivery mechanisms, users are increasingly encountering a frustrating roadblock: "Group version not match" (often accompanied by "HiSuite Proxy new" context).
“Group version not match.”
Navigate to C:\Users\ \AppData\Local\Huawei\HiSuite . Delete the Cache and UserData folders.
