So a custom bootloader unlock patch is required for each sim-unlock software
DaVinci and MultiUnlock Client, unlock bootloader and sim in their own sofware.
SEtool2, non sim unlocked phones, and code sim unlocked phones can be bootloader unlocked via Flashtool.
Unlocking with the wrong patch results in blocked Radio (All radio, not just FM)
Flashtool recognizes omnius unlocked phones, but only restores the bootloader lock, wich enables Radio again.
Currently there is no working patch for omnius, nor seems to be in the near future.
