Never attempt a direct cross-version jump (e.g., dropping immediately from an EMUI 11 package to a base EMUI 10 package).
If the update fails, check the logs.txt file created in the same folder as the proxy app to identify exactly which part of the validation process failed. Summary Checklist for Successful Flashing Base Version Must match target firmware. Ensure CUST Version Must match target CUST. Ensure Preload Version Must match target Preload. Verify CUST Pkg Box Must be checked. Verify Preload Pkg Box Must be checked. Confirm Region (Cxxx) Must match phone variant. If the update fails, check the logs
The current group version utilized in the HiSuite Proxy environment has been identified as outdated and incompatible with the latest modules and services it interacts with. This mismatch has been confirmed through extensive diagnostics and comparisons with the latest version updates.
If you are attempting to downgrade (e.g., EMUI 11 to 10), you must enable the "Rollback" option within the proxy app. Note that this process carries a high risk of bricking or losing USB functionality if done incorrectly.
Use HiSuite Proxy to step downward incrementally. Revert to the minor base version immediately prior to your current build first before pursuing earlier software versions. Alternative Restoration: Recovery OS Method
