How to enter flash mode
When the device is fully powered off, hold Power, Volume Down and Home for a few seconds.

A (turquoise) download mode warning screen should appear, press Volume Up to confirm.

Installation
It is recommended to sideload an android recovery zip through TWRP for the easiest process, since heimdall freaks out about the subpartitions in SYSTEM and won't move past ~7%.
