Install LineageOS on Redmi Note 12/Pro via Fastboot Commands
The below process will wipe off all the data from your device, so please take a complete device backup beforehand. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps.
STEP 1: Install Android SDK
First and foremost, you will have to install the Android SDK Platform Tools on your PC. This is the official ADB and Fastboot binary provided by Google and is the only recommended one. So download it and then extract it to any convenient location on your PC. Doing so will give you the platform-tools folder, which will be used throughout this guide.
STEP 2: Enable USB Debugging and OEM Unlocking
Next up, you will also have to enable USB Debugging and OEM Unlocking on your device. The former will make your device recognizable by the PC in ADB mode. This will then allow you to boot your device to Fastboot Mode. On the other hand, OEM Unlocking is required to carry out the bootloader unlocking.
So head over to Settings > About Phone > Tap on Build Number 7 times > Go back to Settings > System > Advanced > Developer Options > Enable USB Debugging and OEM Unlocking.
STEP 3: Unlock Bootloader on Redmi Note 12 Pro
Next up, you will also have to unlock the device’s bootloader. Do keep in mind that doing so will wipe off all the data from your device and could nullify its warranty as well. So if that’s all well and good, then please refer to our detailed guide on How to Unlock Bootloader on any Xiaomi Device.

- Now, transfer this system.img file to the platform-tools folder.
STEP 5: Extract vbmeta from Firmware
- First off, download the stock firmware for your device.
- Make sure to download the same firmware which is currently installed on your device. You could verify the same from the Build Number.
- Then extract the firmware. In the case of Xiaomi, you can extract the TGZ and TAR via 7ZIP.
- Once extracted, copy the vbmeta.img and transfer it to the platform-tools folder on your PC.
STEP 6: Boot Device to Fastboot Mode
- First off, connect your device to the PC via a USB cable. Make sure USB Debugging is enabled.
- Then head over to the platform-tools folder, type in CMD in the address bar, and hit Enter. This will launch the Command Prompt.
- Type in the following command in the CMD window to boot your device to Fastboot Mode
adb reboot bootloader
- To verify the Fastboot connection, type in the below command and you should get back the device ID.
fastboot devices
- If you are not getting any serial ID, then please install the Fastboot Drivers on your PC.
STEP 7: Disable Verity Check
Type in the below command to flash the vbmeta and hence disable the verification check on your device
fastboot --disable-verification flash vbmeta vbmeta.img
STEP 8: Flash LineageOS ROM on Redmi Note 12 Pro
- As of now, your device will be in the Fastboot Mode. So type in the below command to boot to FastbootD Mode
fastboot reboot fastboot
- Now delete the logical partition to free up some space on your device:
fastboot delete-logical-partition product_a
- You may now flash the GSI ROM via the below command [system.img is the name of the GSI ROM]
fastboot flash system system.img
- NOTE: Make sure that the system.img is being flashed in the same partition whose product partition is deleted. In our case, product_a is deleted, so system.img is being flashed to the system_a partition. If that is not the case with you, then you’ll get a not enough space to resize partition error. In such cases, either delete the other product partition [b] and then flash system.img there [b] or flash the system.img to the partition [a] whose product is deleted [a].
- Once the GSI is flashed, you’ll have to do a format data, so use the below command
fastboot -w
- Finally, reboot your device to the newly installed OS via the below command
fastboot reboot

Whoops. That wasn’t the comment we were looking for. As far as copy-paste is concerned, yes, the steps 1 to 5 are same across all Xiaomi phones, so you might see some similarity. But the part from where the actual flashing begins, it’s completely different for each device. Anyways, let me know where you got stuck and I’ll be more than happy to sort out that issue.
