Have you lost all data? Try this it worked for me!
I lost all data on my phone today but was able to find a fix incase I am not the only one
I have been running Liquid Rom and I have not changed anything for the past few days but suddenly lost all data 3G and 4G.
Verizon support was no help however I was able to fix it by doing the folowing.
Hit Edit Mode
Type PW of 000000
Hit Modem Settings
Look for REV A and hit it
Select Enable instead of eHRPD
Hit Commit Changes
Got Data Back and am still able to do Voice and Data at same time.
I was told there are some problems with verizons new eHRPD network which is supposed to be what handles Voice and Data Simulcast but as I said I can still surf and talk at the same time.
Just posting incase anyone else runs into this problem.
Update... Verizon sending new phone as I am tired of not having 4g I will post more when I get it
