MIUI 9 FAQs

Q: Could developer version ‘upgrade’ to stable version?

A: The answer is yes. But you can’t use the OTA method to update, and can only flash the full ROM. As developer version is actually advanced than stable version, there will be data conflict between the two versions. Therefore, please wipe all user data in Recovery mode before flashing the ROM.

Q: Are there any notes I need to take before upgrading to MIUI 9 global stable version?

A: It’s highly recommended to back up user data before updating. OTA update is a safe procedure, since it’s not necessary to back up data. But if you update using full ROM, it’s better to back up all of your data to a computer. Please don’t update accross MIUI versions (experimental / developer / stable). If you really need to update accross MIUI versions, make sure to wipe all user data in Recovery mode before updating.

Q: How to upgrade my phone to MIUI 9?

A: If you’re using MIUI V5/MIUI 6/MIUI 7/MIUI 8 global stable version on your device, you can update directly on your deivce via OTA, or flash the full ROMs in recovery or using Mi PC Suite. If you’re using MIUI China Developer or China Stable version or Global beta version, you can flash the full ROMs in recovery mode only after wiping all user data.
