## Walkthrough

Overall, it was a very simple flash experience.

### Unlock the bootloader

Same as Sony's devices, Fairphone required us to applied a "unlock code" before we unlock the bootloader.

https://support.fairphone.com/hc/en-us/articles/10492476238865

1. Find the IMEI 1.
2. Find the device's serial number.
3. Go to the [official Fairphone website](https://www.fairphone.com/en/bootloader-unlocking-code-for-fairphone-3/)
4. key-in the info you got.
5. Get the unlock code
6. tap "OEM unlocking" in "Developer options"
7. Key-in unlock code
8. reboot to fastboot mode
9. coonnect to PC via USB
10. key-in the commend `fastboot flashing unlock` from PC

### Flashing recovery

Same as usual, after unlocked the bootloader, the next thing needs to do is flash a custom recovery, so that I may process to flash custom ROM.

Boot into fastboot mode, use adb to sideload the LineageOS' recovery.

Once it's finished, boot into LineageOS' recovery and progress to the next section.

### Flashing ROM

In LineageOS' official recovery, change the selection by pressing the volumn buttom.

Select "Install upgrade", then use adb to flash the LineageOS 20.

### Rooting

Once we boot into the system, we install Magisk's apk first, and just let it root the ROM. After 1 or 2 times reboot, simply done.

### The end

Not really a difficult experience like flashing custom ROM into Samsung device. That's all.
