Just bought a brand new Nexus 5 from a person wanting to keep his iPhone.
Everything is working fine, except it says "No service" (sometimes with one bar, sometimes with all four). Data is working fine though, but neither SMS/MMS or phonecalls works. Sometimes, when i reset/reboot i doesn't say "No Service", but after one single phonecall it reverts back to "No Service" and only data works again.
Iv'e tried resetting with the firmware on the phone from the start, tried flashing both kot49h and krt16m, tried getting a new sim (which works fine in my old Nexus 3), tried different radio-settings but nothing works for me.
Any thought of, what I can do? (before I ship it off to repair, which would cost quite a lot)
Thanks, in advance!
