"Unfortunately the process com.android.phone has stopped" after upgrade to Lollipop on my S5 I upgraded (over the air) to Lollipop and now the phone process keeps crashing. I tried to wipe its data (actually, in Application manager there are 3 'Phone' apps), tried turning off (including taking out the battery), tried deleting the cache.

Is there something more I can do except reset?
You can reinstall Lollipop by installing ODIN onto your computer.

and then you download lollipop, that is compatible with odin, for your S5 HERE.

Your model number for your S5 on the phone underneath the battery. You search that on the website.

These are the steps you do next


Turn off phone.
Hold the Volume Down Button, Home button, and Power button.
Ignore the warning message and press the volume up button to continue.
Connect Phone to Computer
Allow computer to install drivers.
Extract the ZIP file of Lollipop into the ODIN FOLDER.
Open ODIN
Click on the PDA button.
Select the extracted *tar.md5 file.
Click Start!
You should be running Lollipop before you know it!
