A:
There are dozens of Hk8 Pro Max variants (Hk8 Ultra, Hk9, Hk8 Plus). Check the sticker on your charger—if it says "Model: HK8 Pro Max V3," this guide applies. If it says "V1," you need a different app (typically "FitCloudPro").
A:
Generally, no. The Hk8 Pro Max lacks a native rollback feature. The only way is the manual PC flash method described in Section 6.
