How to enter flash mode

Recovery: With the device powered off, hold Home + Volume Up + Power.
Download: With the device powered off, hold Home + Volume Down + Power.

Sometimes, to enter Recovery it is needed to first enter Download mode, then again hold Home + Volume Down + Power and while screen goes blank, switch to hold Home + Volume Up + Power.

Unlocking

In Android go to settings -> System -> About phone and tap the build number 7 times. Then go to settings -> system -> developer options and enable OEM unlocking

Installation

installed system directly on device:

pmbootstrap install
pmbootstrap flasher flash_rootfs
pmbootstrap flasher flash_kernel # after this command finishes, device reboots and pmOS starts :-)
had to follow USB_Network#Assigning_an_IP_address as IP to host computer was not automatically assigned:
- sudo ip link set TheNetDevName address 12:12:12:12:12:12
- not always needed?: sudo ip address add dev TheNetDevName 172.16.42.2/24; sudo dhclient -v TheNetDevName
ssh -p 22 user@172.16.42.1

Developer Notes

device is nearly identical to Samsung Galaxy Tab S2 9.7 Wifi (samsung-gts210vewifi) aka. SM-T813, just has LTE modem additionally.
linux-samsung-gts210velte (vendor-kernel 3.10.102) only works if compiled with gcc6 right now, otherwise get 'Unhandled fault: alignment fault (0x96000061) at 0xffffff8001787f4c' errors on kernel startup, and device always reboots.
