How to flash Custom ROM on Mi Max Pro with locked / unlocked bootloader
If you haven’t previously flashed your phone and have no experience with TWRP, you may first try installing the official MIUI ROM since that is much easier. While Custom ROM installation is a little bit more complicated.
- Download Custom ROM you want to flash. No need to unpack the .zip archive.
- Download TWRP Custom Recovery for Mi Max Pro: TWRPMax(32Gb).rar | TWRPMax(64-128Gb).rar
- Open MiFlash and install TWRP for your phone model. The process of flashing is described above. From the links above you can download TWRP Custom Recovery for MiFlash installation. You must first install the Global or China 18.104.22.168 MIUI ROM on your device before flashing TWRP. This will give you the option to install TWRP without unlocked bootloader. On newer ROM version you’ll have to unlock bootloader first and only after proceed to flashing custom recovery.
- After you’ve flashed TWRP do not disconnect your device from PC.
- Boot into Custom Recovery by pressing “Volume Up” + “Power” buttons. If TWRP asks for password, tap cancel and allow system partition modifications.
- Go back to main menu and tap on “Wipe”. Select “Data”, “Cache” and “Dalvik” partitions.
- Back to main menu again and reboot into system.
- Go to “Mount” and enable “MTP”.
- Copy downloaded custom ROM .zip archive to phone internal memory.
- In “Mount” disable “MTP” and safely remove USB cable.
- In case you see a checkmark against “system”, remove it to unmount “system” partition.
- Now go to “Install” menu and select ROM .zip file. Confirm with swipe to continue. Flashing will take around 10-15 and you’ll see a successful message in the end.
- Reboot into system.
- You should see a Mi logo on a black screen. First startup will take around 10 minutes. If you can’t boot into the system, you can try rebooting into TWRP Custom Recovery and try installing ROM once again, this help sometimes.
