Let’s diagnose the root cause. Check these five factors first:
Let’s walk through a real-world example.
User’s issue: Trying to downgrade from EMUI 13 to EMUI 11 using HiSuite Proxy. Error: "Group version not match". group version not match hisuite proxy work
Diagnosis:
The Base firmware was LGRP4, but the CUST expected N29. The group names differed. Let’s diagnose the root cause
Solution:
The user searched for Base firmware specifically labeled ELS-N29-OVS 11.0.0.260. Once they replaced the Base firmware with the correct group identifier (N29 instead of LGRP4), HiSuite Proxy worked flawlessly.
This error appears when HiSuite Proxy detects that the firmware files you selected (or that HiSuite downloaded) don’t belong to the same software group/release package. Huawei firmware often comes in multiple parts (base, cust, preload, etc.), and their version strings must match exactly for HiSuite Proxy to allow flashing. The Base firmware was LGRP4 , but the CUST expected N29
Before diving into the error, let’s quickly establish the context. HiSuite Proxy is a third-party tool (developed by users like ProfessorJTJ) that acts as a middleman between the official Huawei HiSuite PC application and Huawei’s firmware servers.
Users turn to HiSuite Proxy for several reasons:
HiSuite Proxy works by intercepting the official HiSuite update requests and redirecting them to a custom URL (usually a Google Drive or GitHub link containing the firmware files). When everything works, it is seamless. When it doesn’t, you get the "group version not match" error.
