to be honest is quite hard to remember if I installed the latest modem.zip in e.g. April as Baseband version is only an indicator if I’m up to date. In particular as I relay on the LineageOS updates (which also seems update modem as I haven’t updated from v17 to v18 by myself).
Would be appreciated if you post a reply in FP2 modem firmware as soon as a new version is up. You can delete this a couple of days later but I subscribers will be informed that there is something new.
