verizon tech says only thing to do is a factory reset.
phone will not find data network while set for ehrpd or when Rev. A is enabled and LTE mode is on.
Rev. A enabled and CDMA auto (PRL) together will find 3g. when either ehrp or LTE mode is set it won't find the mobile network. after turning it on through "wireless & networks" (check box) it bliks from "turning on.." to "use mobile network when wifi is unavailable" a few times then hangs on "use mobile network when wifi is unavailable" but never finds data.
and it obviously won't find 4g either.
went through all of this w/ verizon tech last night and all he could say was "switching back and forth between 4g and 3g settings is not recommended" and that a factory reset was the last option.

any help appreciated.

 

i've done the 4636. that's one of the things the verizon said was unrecomended. also did the airplane mode toggle. have not powered it up w/out the Sim card though.

 

it seems to try but blinks from "turning on" to the "..use..blah...when wifi is unavailable.." a few times then hangs.

again, this is only when it's set for lte or ehrpd.(4636 and 778 work arounds) when it's in cdma mode w/ rev. a enabled it will have reliable 3g.

i'm going to do the factory reset. if it still doesn't work then it's a hardware issue...right?

if it does work then i want to know what causes the problem. why ehrp often doesn't work and what the "unknown affects" are when switching from cdma to lte.... instead of verizon trying to sell me the extended life battery..."it's really not THAT bulky".... ok

 

WormDoes had it right. did the factory reset and it fixed the problem. finds network and 4g. not really that hard to get the phone back to where it was. thanks for the input.
