Please check the instructions for our two installation methods:
eRecovery Method - This is our supported, reliable method. Please use this method. Note: Might not work for updating EMUI 5 to EMUI 8. For that, use below instructions.
(If you can't set the DNS on your router easily, we released this tool to help you when using the Hotspot method.)
HiSuite Method Only use this method for updating EMUI 5 phone to EMUI 8. Otherwise DO NOT USE THIS - use the eRecovery method.
For instructions and support regarding rebranding to another region/model (including converting single-sim to dual sim), see Here.
