Cannot update Lineage: Error 7

[Lk2]

Hi all!

I was trying to upgrade my Linage to one of the latest builds and I got the Error 7, assert failed when checking the modem timestamp.

I was reading here and the proposed solution is to install an official MIUI ROM, to get the firmware upgraded, and then reinstall Lineage, but I also read that it is possible to flash only the radio from TWRP, keeping my away from wiping my mobile.

Is it really possible? Where are the links? I tried myself to find out the way to download and flash only the radio firmware but I didn't find anything.

Thank you in advance!

Thanks a lot!

Is it recommended to flash any other firmware part? I read something about that on Reddit, people recommending to flash the entire MIUI ROM only to get those parts too...
