MIUI 9 Global Beta ROM 8.1.18 – How to Download?

The users who are using MIUI 8 Global Beta ROM can grab your update three methods:

OTA (Over the Air) Method

The simplest, risk-free, and the easiest way to jump to MIUI 9 is Via OTA. But let us tell you that if you want to go from Stable to Beta Version of MIUI 9, OTA update is not possible. You have to use the Fastboot method or Recovery method. Here’s the OTA method mentioned in three simple steps:

1. Open Mi Updater App
2. Click software update
3. Confirm and Download the update

Or:

1. Go to Settings
2. Click My device
3. Go to MIUI version
4. Click System Update

Or

1. Click the update now in the notification bar.
2. Wait for the downloading to complete
3. Click reboot

Meanwhile, the user who are using MIUI V5 / MIUI 6 / MIUI 7 / MIUI 8 stable ROM can upgrade their phones to MIUI 9 via the fastboot method.

Fast Boot Method

This one is a little bit complicated and risky. If you haven’t received the update for your supported phone, you can’t try this. Moreover, it’s the only way to shift from Stable to Beta or Beta to Stable ROM or Developer to Stable / Beta.

• Install Mi PC Suite – here
• Download Drivers – here

How To Make a Local Backup?

• Go to settings – additional settings – backup & reset
• Click ‘Local backup – Backup’, to create the backup and move it to PC before flashing
• Do remember, it includes only apps so multimedia files need to be backup separately

Steps Before Fast-booting

Safety Measure: We recommend to backup your data before fastboot. Shifting from Developer mode to Stable requires a complete wipe.
