TECHNISAT MIB STD2 CM - where to find VCRN after replace EMMC?

Hi!
I have a TECHNISAT MIB STD2 Composition Media version mst2_us_vw_pq_p0247t under repair. It have a faultly EMMC.
Ater programming new EMMC with same version of image, head unit is powered on. But Ingeneering menu FEC/SWaP section there is empty.
I need to activate SWaP codes but without VCRN code I can't to do this.
In the new EMMC chip section RPMB is empty.
After flashing from emergency download with same version RPMB section is empty too.
Where I can find VCRN code after replace the EMMC chip?
Or how to activare FEC/SWuP codes in this case?
Thanks!

I know about it. The flie tsd.mibstd2.system.swap I already patched. And now need to activate the SWaP code. For this need the VCRN code. But I don't know this code!

Hi

RPMB partition will be empty after replacement of the emmc. Therefore the VCRN will not show. It is part of component protection system. RPMB/emmc holds data in regards to that. So after replacement its not possible to de online removal of component protection. If you check proces you will see field is empty that should show VCRN.

No it is not possible to activate unit with Odis online. Like explained, some inof is missing so proces is not complete.

Other ways might be possible to activate ;)
