yes i'm rooted and i already tried going to back to stock, didn't seem to fix anything.

OK so if u went back to stock u should take it to a sprint store and tell them that it just started to happened and u did a factory data reset and nothing changed.

that isn't changing your radio band, so i'm guessing that you didn't try it. it's a pretty stupid idea, but who cares as long as it works, right? dial *#*#4636#*#* and click on phone information. then push menu, select radio band, and choose USA. otherwise, take it into sprint lol

This happened to me today. Flash to a stock rom (if you aren't already) and update your profile and PRL. Did the trick for me.
Good luck

Its not an issue really. It is how the rest of the world sets their numbers. And lets not forget where HTC is. Your best bet is to just set up your numbers with the +1 in front like the rest of the world. They are not gonna change this for the few US based phones that come out. Oh and its ATT that is supposed to make those changes.

I'm pretty sure this doesn't fix it for everyone. (Definitely doesn't fix it for me.) Is there any other step besides adding +1?
All my contacts are +13333333333. The names eventually show up, but a reboot makes them disappear.
EDIT: I do agree though, it wouldn't be an issue otherwise.
For some reason when i do the check for updates it tells me my phone is up to date. I know i can download the update manually but i would rather not have to as it wipes my phone. Are their any solutions ?? Thank you in advance for anybody who assists me
I don't like signatures....

You can check or keep waiting. Or you can use one of the roms that are have been based on this release and been around for over a week
does it affect the wifi hotspot tethering when adding a custom APN to all who updated officially 2.3 GB?
can anyone confirm this..Thanks

SIM issues

Ok its been few months, I have been on skyics 2.3.5 for a while, can't use ICS yet.
I started getting sim has been removed, I reboot and its fine, not sure why this is happening, I had it unlocked about a month a go and use in europe with out issue with ekit SIM. Came back and for a week it was fine, now this started and its very annoying any one seen this?
Last time I had an issue it was hardware and had to replace phone. Now I don't want to replace phone and advice? Before I start changing the ROM etc?
Sent from my SAMSUNG-SGH-I727 using XDA
what was the hardware problem before ?
Had to replace phone. Not 100% sure what was wrong exactly but ATT replaced phone.
Can this be traced back to ROM or radio some how? Or maybe my SIM?

You can cross-check your SIM's function in another similar/unlocked phone. Also maybe try flashing a different modem.

Well that's the thing, the sim works here afyer reboot. Good call on radio flashing diffrent one now.
Im starting to think that changing SIMs might work as thia usually happenes when the phone is in my pocket. Lets see how flashing radio goes. Maybe I need to move to a new ROM, when is official ICS out?
Sent from my SAMSUNG-SGH-I727 using XDA
Ok after reflashing radio and clearing cache etc.. it did it again.
Just walked out of ATT store with new SIM lets see how it is.

At this point, I'm guessing SIM will clear it?... Android 4.0.x fourth leak just dropped from Samsung. Official ICS for SR is (unofficially) overdue.

[Q] Searching for Service

I haven't found any answers on this, but once or twice per day my phone will be stuck on Searching for Service even though in the status bar, it shows like 3 bars of 3G or 4G. Data still seems to work, but this seriously drains the battery. I'm on stock unrooted HD. Any advice is appreciated. I already tried a new SIM. I bought this phone here on xda, no box, so I doubt Verizon would let me exchange it.
I know this is a silly question but what radio is installed?

VRLG7 is a downgrade in release but does not hurt to reflash any of the modems to see if it fixes problem and which works better for your area. Affects 3G more than it does 4G..

Maybe root it and try a custom kernel, though I'm not positive that will help. Possibly a total wipe and reinstall of a stock system? If you bought it from someone here on xda, chances are it has seen some mods. Hopefully someone with more knowledge on the subject will chime in for ya. I just hope you didnt buy someone else's problem... :-\

I got it and it had never been rooted before. I rooted it, used custom ROMs, they all weren't my cup of tea, so I unrooted and flashed the stock HD images via ODIN yesterday. I just flashed the HE radio, and it seems to at least be a bit better. I'll keep experimenting.
It's still dropping signal. Sounds like I'll be calling up Verizon tonight.

You guys are missing what I am asking for. There use to be a app in the play market by [email protected] called Phone Info. Not the normal phone info that comes with the stock rom. This app use to allow you to change the mode on your phone from the CDMA to GSM if you had a the sch-i535. About 2 weeks ago they deleted it from the market, and now I need it. I just need someone with that .apk file.

The 4636 code does the same exact thing as phone info.... same exact thing. Type that code in and scroll down... Magic! But if you still aren't willing to try it or give any more information on what ROM or anything you are using, pm me your email and I'll send it to you.

You dont need any apps for that. I know you're talking about global mode (switch the radio to gsm). Thats just in settings>more settings>mobile networks>network mode
Unless I'm still not understanding what you want to do. It sounds like you want to switch to GSM mode...the above does it.

This.
Or Just do the OTA to Jellybean! Is there a reason you didn't do it? That option was only enabled in 4.1
if you still want it...
I found out that you don't need it just go into settings/more settings/mobile networks/network mode and there you go you can change to global LTE/CDMA or GSM/UMTS
Net Monitor Worked for me instead of Phone info.
I am running CM 10.1 nightly.
The *#*#4636#*#* brought up the ability to change the mode to GSM, but if i go into settings/more settings/mobile networks/network mode I only have ' LTE/CDMA/EvDo' and 'CDMA/EvDo auto.'
I am travelling to UK, Italy and Spain next week so I am trying to ensure this will work. I will be staying with the Verizon SIM and incurring the roaming charges (business phone) and won't be using another SIM.
Thoughts?
want to change from cdma to gsm also

I have a new N5 and its unlocked and rooted. I get LTE just fine on the stock rom but when I flash any custom roms, LTE doesn't work. Even when I restore my backed up EFS on the custom rom, LTE still doesn't work. Anytime I nandroid back to my stock rom, LTE works fine. Any ideas or help will be appreciated.

I think there's some extra APKs you need to add to custom ROMs.
I fixed the issue. I unrooted and returned my phone back to stock. Then I found a sprint. Zip that you flash with custom roms and that worked.

Its a zip to flash after roms that sets the correct APN settings for sprint. I can't remember the thread I found it in though. But it was for the same issue I was having with my LTE/3g switching.

The reason I am searching through posts is this: my 3G works fine. But when it kicks over to LTE... Nothing happens... In a minute or two I may get 4 mbs or something pretty good and then nothing again. I need it to actually work. My wife has the same issue on her S4 and she is stock. It switches over to LTE.... Nothing. I have LTE off mostly. Steady slow 3g is better than no progress on LTE.
update profile
Should provide the correct settings in the custom Roms assuming the creator added the update profile features. I know cm does
