Hi! when I install any CM based rom I get the unknow baseband/imei/network,but my SN is still there.

I have the i9300 version with i9300XXUGNA8 and CRYSTALROM V3, the SN does not changes when i flash CM (see attached screenshots, i censored the SN just ni case, but it is not lost or unkown)

I have backups of my EFS via TWRP, either way, when I restor the crystalrom backup, without restoring the /EFS it works again, so i do not what is wrong and what guide/steps to follow to fix it.

I'm unsure on what steps to follow to fix it.

- Do I use this patch?
- Do I follow the steps from here? but which ones as it describes several methods and none, as I see it, is regarding about my exact situation (off course unless i just dont get it, that is why i'm asking for a bit of help/guide/directions)
- Do I flash another radio/modem/baseband?

Can someone point me in the right direction please? Thank you for your time.

edit: i also read here of course.
