alioth

Warning: The provided instructions are for LineageOS 20. These will only work if you follow every section and step precisely.
Do not continue after something fails!

Basic requirements

Read through the instructions at least once before actually following them, so as to avoid any problems due to any missed steps!
Make sure your computer has adb and fastboot. Setup instructions can be found here.
Enable USB debugging on your device.
Make sure that your model is actually listed in the “Supported models” section here (exact match required!)
Boot your device with the stock OS at least once and check every functionality.
Warning: Make sure that you can send and receive SMS and place and receive calls (also via WiFi and LTE, if available), otherwise it won’t work on LineageOS either! Additionally, some devices require that VoLTE/VoWiFi be utilized once on stock to provision IMS.
LineageOS is provided as-is with no warranty. While we attempt to verify everything works you are installing this at your own risk!

Warning: Before following these instructions please ensure that the device is currently using the firmware version mentioned below. If your current installation is newer or older than the required version, please upgrade or downgrade to the required version before proceeding by following this guide.

Device model	Firmware version
Mi 11X India	V14.0.2.0.TKHINXM

Checking the correct firmware

Installation on your device requires a specific firmware version to be installed before you continue.

Being on another custom ROM, including unofficial builds of the same version of LineageOS, does not ensure that this requirement has been fulfilled
Please re-read this section as many times as necessary to fully understand the requirements

Note: If you are unsure what firmware version you are currently on, we strongly recommend following this guide, just in case!

Failing to install the correct firmware version prior to installation may result in failure to install LineageOS, unexpected crashes post-installation, or permanent damage to your device!

Unlocking the bootloader

Note: The steps below only need to be run once per device. They require a machine running Windows 7 or newer.

Warning: Unlocking the bootloader will erase all data on your device! Before proceeding, ensure the data you would like to retain is backed up to your PC and/or your Google account, or equivalent. Please note that OEM backup solutions like Samsung and Motorola backup may not be accessible from LineageOS once installed.

Tip: It is highly recommended to have the latest official MIUI stable package installed on the device, before proceeding with unlock.

Create a Mi account on Xiaomi’s website. Beware that one account is only allowed to unlock one unique device every 30 days.
Add a phone number to your Mi account.
Insert a SIM into your phone.
Enable developer options in Settings > About Phone by repeatedly tapping MIUI Version.
Link the device to your Mi account in Settings > Additional settings > Developer options > Mi Unlock status.
Download the Mi Unlock app (Windows is required to run the app).
Run the Mi Unlock app and follow the instructions provided by the app. It may tell you that you have to wait up to 30 days. If it does so, please wait the quoted amount of time before continuing to the next step!
After device and Mi account are successfully verified, the bootloader should be unlocked.
Since the device resets completely, you will need to re-enable USB debugging to continue.

Flashing additional partitions

Warning: This platform requires additional partitions to be flashed for recovery to work properly, the process to do so is described below.

Download the following files from here.
- boot.img
Power off the device, and boot it into bootloader mode:
- With the device powered off, hold Volume Down + Power. Keep holding both buttons until the word “FASTBOOT” appears on the screen, then release.
Flash the downloaded image files to your device by typing:
```
fastboot flash boot boot.img
```

Booting a custom recovery using `fastboot`

Download Lineage Recovery. Simply download the latest recovery file, named vendor_boot.img.
Important: Other recoveries may not work for installation or updates. We strongly recommend to use the one linked above!
Connect your device to your PC via USB if it isn’t already.
If your device isn’t already in fastboot mode, on the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:
```
adb reboot bootloader
```
You can also boot into fastboot mode via a key combination:
- With the device powered off, hold Volume Down + Power. Keep holding both buttons until the word “FASTBOOT” appears on the screen, then release.
Once the device is in fastboot mode, verify your PC finds it by typing:
```
fastboot devices
```
If you don’t get any output or an error:
- on Windows: make sure the device appears in the device manager without a triangle. Try other drivers until the command above works!
- on Linux or macOS: If you see no permissions fastboot try running fastboot as root. When the output is empty, check your USB cable (preferably use a USB Type-A 2.0 one or a USB hub) and port!
Tip: Some devices have buggy USB support while in bootloader mode, if you see fastboot hanging with no output when using commands such as fastboot getvar ..., fastboot boot ..., fastboot flash ... you may want to try a different USB port (preferably a USB Type-A 2.0 one) or a USB hub.
Flash a recovery on your device by typing:
```
fastboot flash vendor_boot vendor_boot.img
```
Note: Outdated fastboot releases dropped legacy A/B support, so it might attempt to flash to boot__a / boot__b rather than boot_a / boot_b if you try to flash boot. In this case, you must update fastboot to a release newer than or equal to 31.0.2. Alternatively, you can manually specify which slot to flash to based on what slot fastboot failed to flash to. For example, if fastboot fails to flash to boot__a, you must flash to boot_a.
Now reboot into recovery to verify the installation.
- Type the command:
```
fastboot reboot-recovery
```
Note: If your recovery does not show the LineageOS logo , you accidentally booted into the wrong recovery. Please start at the top of this section!

Installing LineageOS from recovery

Download the LineageOS installation package that you would like to install or build the package yourself.
- (Optionally): If you want to install an application package add-on such as Google Apps (use the arm64 architecture), please read and follow the instructions on Google Apps page
If you are not in recovery, reboot into recovery:
- With the device powered off, hold Volume Up + Power. Keep holding both buttons until the “MI” logo appears on the screen, then release.
Now tap Factory Reset, then Format data / factory reset and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage, as well as format your cache partition (if you have one).
Return to the main menu.
Sideload the LineageOS .zip package but do not reboot before you read/followed the rest of the instructions!
- On the device, select “Apply Update”, then “Apply from ADB” to begin sideload.
- On the host machine, sideload the package using: adb sideload filename.zip.
  Tip: Normally, adb will report Total xfer: 1.00x, but in some cases, even if the process succeeds the output will stop at 47% and report adb: failed to read command: Success. In some cases it will report adb: failed to read command: No error or adb: failed to read command: Undefined error: 0 which is also fine.

Installing Add-Ons

Note: If you don’t want to install any add-on (such as Google Apps), you can skip this whole section!

Warning: If you want the Google Apps add-on on your device, you must follow this step before booting into LineageOS for the first time!

Even though you are already in recovery, click Advanced, then Reboot to Recovery
When your device reboots, click Apply Update, then Apply from ADB, then adb sideload filename.zip for all desired packages in sequence.

Note: Add-ons aren’t signed with LineageOS’s official key, and therefore when they are sideloaded, Lineage Recovery will present a screen that says Signature verification failed, this is expected, please click Continue.

All set!

Once you have installed everything successfully, you can now reboot your device into the OS for the first time!

Click the back arrow in the top left of the screen, then “Reboot system now”.

Note: The first boot usually takes no longer than 15 minutes, depending on the device. If it takes longer, you may have missed a step, otherwise feel free to get assistance.
