# Steps to flash microG LineageOS on Sony Xperia SP
## Prerequisites
- A Sony Xperia SP (make sure it says `huashan` in the "About Device" settings)
- A computer (preferably Linux) with:
- an USB slot
- [adb](https://wiki.ubuntuusers.de/adb/) installed
- [heimdall-flash](https://wiki.ubuntuusers.de/Heimdall/) installed (on
Windows you can use [Odin](https://www.odinflash.com/))
- A micro-USB cable which can transfer data
## Preparations
download latest TWRP image from https://dl.twrp.me/huashan/
download latest lineageOS from https://download.lineage.microg.org/huashan/
rename TWRP image to recovery.img
## Unlock the Bootloader / OEM
enable developer options
enable USB debugging in developer options
allow USB debugging access for your PC
unlock bootloader: https://developer.sony.com/develop/open-devices/get-started/unlock-bootloader/how-to-unlock-bootloader/
## Flash TWRP
`adb reboot bootloader`
wait until bootloader mode is active: blue LED
fastboot flash boot recovery.img
fastboot reboot
## Flash LineageOS
First boot into the recovery mode:
* Either with adb: adb reboot recovery
* Or with the recovery mode key combination of your device.
* Note: this is not the same combination for the download mode.
Then go to Wipe + Advanced Wipe to wipe the following partitions:
* System
* Data
* Cache
* Dalvik
Then go to Advanced/ADB Sideload, swipe to the right, and execute `adb sideload lineage-xxx.zip` on your computer.
* When it shows `adb: failed to read command: Success` on the PC, and `Exit code: 1.000000` in TWRP, it has suceeded.
Reboot to start LineageOS!
