How to enter flash mode
In a turned off state, press
+ + then press to continue.How to go back to TWRP
If you're stuck in system loading and you can't enter the Download mode, press
+ to force shutdown. At reboot (on Samsung logo and vibration), press + until the recovery splash comes out.
Installation
Like other heimdall phones, heimdall doesn't seem to like the subpartitions in the SYSTEM partition. It's recommended to use the android recovery zip installer with TWRP on the phone, but you can also install to an SD card/USB Drive and flash the boot.img using heimdall.
NOTE: On firmware versions later than Dec 2021, TWRP may have graphical glitches and/or bootloop (unbrick by draining/disconnecting battery). It is recommended to downgrade your firmware version.
Installing with recovery
$ pmbootstrap install --android-recovery-zip
$ pmbootstrap export
Then copy the zip to an SD card or similiar and install it from TWRP.
Installing to external SD/USB
$ pmbootstrap install --sdcard=<SDCARD/USB LOCATION>
$ pmbootstrap flasher flash_kernel
