Hi there,
I have some serious baseband problems. Don't know if it's bootloader unlock related, because this was the first thing I did with my telephone.
I tried to relock my bootloader, but the problems don't go away. My phone originally ran on a Greece unbranded firmware. My network operator is Vodafone NL. I run version 23.0.1. A.5.77.
Once my connection is unstable, my Z3C sometimes 'forgets' the baseband settings and sets the network type to 'unknown'. I lose mobile data. However, I can still make calls. I can change it back to USA Baseband (I live in Europe) with *#*#4636#*#* --> Information --> select baseband --> 'USA Band'. After that I'm unable to make calls, but mobile data works fine again.
Have to remark that I unlocked my phone BEFORE there was a known backup method of DRM keys, so they're lost forever. I'm trying to find out if my problems are related to this. So far I ruled out:
- Recovery
- Rooted yes/no
- Unlocked/Relocked bootloader
- Different baseband versions
My only solution is to go home, reinstall baseband and all works fine again, till my phone decides to drop signal again. It's starting to drive me nuts. Any advice? And why can I only select 'USA Baseband' from the service menu?
