I am curious if anyone using Leste in this PinePhone (&Pro) thread has upgraded to the mostly-FOSS distro for the modem module. It saves power ind improves call quality as well as mostly solving the wakeup issues.

It is also important to note that there is a fix on the modem distro website if users encounter a non-booting module as happens with upgrades on newer hardware releases, this involves rebuilding the IMEI and other components of the 'firmware' and completely solves this issue.
