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!
