For all who have trouble getting Sprint Data LTE Working

Edit: this post is messy. I have succeeded getting data to work on Sprint on a related Nexus 5 HH. Don't know exactly how but eventually I got LTE working with a Pie Rom on Sprint. Skip to next post it's less messy.

and here are my notes, a bit messy sorry. I am currently trying to get Nexus Hammerhead working with Spring MVNO. (not Freedompop). It''s a huge pain in the [MENTION=1116887]$$$[/MENTION].

The following is my current experience with Nexus 5:

[[[!!!!!Nexus 5 only!!!:eek:n Nexus 5 to do PRL reset I have to be on stock. after that I have LTE only up to Marshmallow roms. I lose LTE and data connection with any rom past Nougat, even if I use the same TWRP as with earlier (2.8.5.x) roms. So it's not because partitions get written over with an incompatible TWRP. Now. Changing buildprop as explained below in my notes ro.carrier=spr gives me LTE after restart, and shows APN entries, but it doesn't last and is gone at next restart, and I cannot edit or select an APN. tried all the resets and going into phone diagnostic menu with different selections, no dice. The only thing I have succeeded thus far with Nougat on Nexus 5 is using the Freedompop_APN_fix.zip, which gives me 3g, but no LTE. Am getting 3mbs on 3G so I can live with that. But the issue seems to be starting with roms past Marshmallow, <<<<<------!!!this info concerns Nexus 5 HH not LG LS-980!!!]]]]]

Here are my notes sorry they are messy and contain some info that has been superceded but might help nonetheless. I have a feeling the trouble I am having with getting NExus 5 HH to work with a current rom and Sprint is similar to the issue others have with LS-980.

Start of messy notes:

<<<<<<sprint lg g2 ls980:

tweaks necessary with cloudy 2.2:

go to buildprop and edit as follows:

ro.carrier=spr(NOT SPR; crashes dialer)

ro.build.target_operator=spr (NOT SPR; crashes dialer)

persist.service.crash.enable=1

Important Note July 2019: with Nexus 5 & CRDroid 7 Nougat after having lost LTE data coming from Marshmallow (working LTE & telephony):

did first one (ro.carrier=spr) others not found, re-booted and had LTE.

This gave me telephony also.

Just changing buildprop as above gave me APN entries in Settings/MobileNetworkSettings. Worked without any apn picked/checked.

Did not need to do data reset, did not need to dial anything.

Update 1 hour later lost lte & telephony again

On Freedompop phone I do not have ro.carrier changed to spr and yet it works. On AOSXP it does not have entries for ro.build.target or for persist.service.crash

Now: with BLISSPOP:

changed buildprop ro.carrier=Sprint (not spr, not SPR). This gave me 3G. Seems I had to do this with RomToolboxPro, the built in kernel whatnot buildprop

did not seem to work.

the above worked AFTER I restored APN with APN app. Used the APN stored with files here (think oct 2015). Doubt this had any effect. Buildprop change had

effect of giving 3G.

since I only seem to be able to receive 3G, I dialed *#*#4636#*#* and switched the radio mode to GSM only from LTE/whatnot. Seems to keep it from hunting for

LTE.

Also:

To to your phone app and dial: *#*#4636#*#*

Go to phone information

Scroll down to a set preferred network type: press the drop down box

Select LTE only for Select LTE/GSM/WCDMA I use LTE/GSM/WCDMA as I don't have full LTE coverage

ALSO TOGGLE ENABLE DATA SERVICES OR SOMETHING SIMILAR

then it might help using APN backup&restore from app store, convert it to system app with an app called app /system/mover or something

Needs to reboot and possibly have permissions restored and cache/memory cleared in rom toolbox

This needs to be backup from a stock rom obviously, and I should have that in my files for LG G2

Then go to settings

hERE I am not certain which settings work best but so far all is working with freedompop

Sprint LTE is indeed working. If you are having any issues, go into Settings/Cellular networks and make sure you're set to CDMA+LTE/EVDO for your preferred

network, auto for system select and Sprint LTE internet n.ispn for your APN. Not sure if it makes a difference if you're on a 2yr plan or the prepaid Sprint

plans, but I personally have the roaming data on (I've got the Unlimited 70$ plan)...

---->Try data, wifi reset option in settings.
