Regarding unlocking, yes since it's Simos 18.1 (SC8) you want "FL_8V0906259H__0001.frf". The only reason you'd need a different file is for Simos 18.10 (SCG). Once the unlock procedure is done you can then full flash the correct FRF/bin for the car. From that point onwards you can either do a unlocked full or calibration flash from within the GUI.
You won't need to redo the immo off as that's stored in DFLASH (EEPROM) and isn't written during any flashing process within VW_Flash. In case you don't already have a boot tool you can use the following made by Brian to build your own for this ECU: bri3d/TC1791_CAN_BSL
from vw_flash.
Simos18 Immo Off is not done in DFlash alone. Some tools correct and re-encrypt the VIN in ImoDat in the DFlash, but all Immo Off files alter the ASW to hardcode the stStatFact
to a specific value, bypassing the immo logic.
To answer your questions:
- I have no idea what any commercial flashing tools do really. If they just put CBOOT into Sample Mode like my patches, then they will be compatible. If they have some proprietary protocol add-on or a different method of bypassing signature checking, they won't. Unfortunately I can't really guarantee anything when it comes to commercial tools as I have no idea what weird additional patches they may have applied.
- Yes, but not right now. I should add this feature. Checking the Hardware Number while the ECU is already in programming mode is the easiest tell. I will look into adding a button for this.
- Yes, your understanding of the unlock process is correct.
As for Immo Off:
2)use vehical or other software to do immo off
Yes, and note that you need to use a bench/boot tool to write immo off the first time, you can't flash over UDS while Immo is active.
3)unlock it with FL_8V0906259H__0001.frf
Yes.
4)Flash it with full .bin unpacked from : FL_5G0906259H_0001.frf
No, just flash it with the .bin you already got back from your immo off service. This way you'll keep the immo off.
