Tiny Copy and Paste mistake...
Now should work.
SM-R840 and SM-R850 p7
Code:
TIZEN_55_untested_GW3_smR840_smR850_p7_v1.bat
LTE devices like SM-R845F and SM-R855U... p8
Code:
TIZEN_55_untested_GW3_LTEseries_smR845_smR855_p8_v1.bat
Funny...
Dump is empty.
So seems they increased Security by read protection...
But to write empty file to STEADY partition removes RL again...
