How to install lineageOS or Cyanogenmod

This tutorial focus on hardcore users with terminal skills

Linux guide

My true intention was to do everything using adb, however i never figured out how to do that, so i gave up and used heimdall instead

Personally i think this part is the trickiest...

install heimdall (Link)

Arch:

sudo pacman -S heimdall

it should be similar with other distributions... (if you are using Windows, use Odin)

Download the latest TWRP image for your phone: Link to TRWP webpage

Reboot phone into download mode (My Samsung phone uses: home+volume down+start)

Or maybe this command works...

adb reboot bootloader

as su run:

heimdall flash --RECOVERY /path/to/recovery/file/on/your/computer

First reboot into recovery mode, you can do that with:

adb reboot recovery

Now do a clean cache/factory reset

Install LineageOS with:

adb sideload /path/to/rom/file

DONE!

*If you want to reflash your rom, only do this step and skip the recovery part.
