Wrap Up
If you are in Stock firmware, Use Internal Memory method. It is comfortable and safe; You can update like a Regular OTA Update. If you moved to a different region other than your purchased area, you could try with VPN to get the update. But if you were already using Custom OS or Rooted devices, You can try TWRP Method. Donât download any third-party apps; sometimes, it may trigger the updates process. In my opinion, Color OS is better to compare with some other Custom Skin OS like MIUI. So try to use this OS instead of a Custom OS. But the decision is your choiceâŚ:)
