Stuck in 1x mode?

Hello everyone.
I just got my phone back from Samsung after it wouldn't power on, then had trouble getting it to stay connected long enough to activate. So, I brought it in to town, hooked in to wifi, and had no issues. Got the phone activated, waited for a while, updated the PRL and Profile, and waited around to see if it would start working for me. Unfortunately, it was still not working very well. Put on the 1x/3g mod to see if it was actually getting 3g. Found that it was not... Finally, I contacted sprint to see if they could help on tech support. He said he would contact the network people...
I was like, hmm... at different location now, checked at the sprint store, updated one of their phones PRLs, and it seemed to start running slowly too... so I downgraded my PRL to see if that would help, it did not. Finally, I put on the 00001 PRL really quickly to see if I could get 3g... seems it didn't leave sprint or the 1x.
So, put it back to the original... was wondering if anyone has some advice?
Thanks much.
UPDATE: So, the radio has been flickering on and off for data reception, went up to Green Bay today and it went into 4g, then 3g, then nothing for a while, then back again...
Right now it is on 4g again.
Is there any way to check if the radios may have something not working? I would say maybe it is just network upgrades, (really, really hoping this is the case), but then I would think that Sprint would have said something when I contacted them about there being upgrades....
Thanks.
Take it to a store and ask them to test the radios. They could be faulty.
Mines been acting the exact same way...altho mine has not had problems before needing to be sent to Samsung.
2 weeks ago it just started not going into 4g as much as it used to...and RANDOMLY totally dropping any data connection 10x a day. Literally no 3g/4g for 2+ minutes at a time..no amount of airplaine mode/restarts fixes it......its like im back to the SgS2 days.. ****im sick of Sprint/samsung

It's sprints fault, not samsung. I have the same data drop problems, especially around NYC/NJ. I've had the same issue on my previous S3. My GF has no such issues on her S4 or her previous S3, but she has AT&T. Chances are Sprint is doing something with the network in your area currently.
Try this
1 - update profile
2 - update prl
3 - open the dialer and enter ##72786#
Your phone will reboot and go thru the activation process
If that does not help, call sprint and find out if there are any network vision enhancements in progress for your area. Unfortunately when Sprint does their updates it gets REALLY BAD until they are done

[Q] How to bypass the Verizon G2 Setup Screen URGENT!

Basically i bought a Verizon LG G2 because i did a little research and found out it is gsm unlocked. So i received the phone and i factory reset the phone to make sure it was a fresh start. After i factory reset the phone would not get past the setup screen and got as far as where i had to insert Verizon sim for activation. I have a T-Mobile Sim card so i cannot get past the screen. i have seen people get past that screen on the G2 i just wanted to know how i can get past the setup screen too.
Thank You!
Try tapping all the corners clockwise on the first screen. That's the usual method.

Just curious why get a Verizon one?
Because it supports Verizon LTE and is unlocked for GSM out of the box.
It also has Qi Wireless Charging.
I'm not sure if it will supports other carriers LTE bands though but it should.
Great for people that use Verizon and travel so you can quickly fall back to a local prepaid SIM if need be.
Tmobile doesn't even have LTE, just GSM, so you should be good there. 4G is meh anyway. I typically get 7-8mbps on 3G, which is perfect for cell service. Is pushing 80mbps on Verizon 4g really necessary?

I just got the verizon g2 as well. On t mobile, havnt got 4g, or 3.5G but haven't been to an area with it yet.
To get past setup, hit Up, Down, Back, Back. (thats what I found but didn't work) I tried up down back back a few times, then I think UP, DOWN, Back, Sleep did it.

[Q] 4G issues

Hello, i am unable to get 4g on my g2. It is international version. Any ideas on how to solve this? I have alresdy called my telco and requested forb4g to be on. Unfortunately still no 4g after 2 days..
Same problem with my d802.
No clues how to fix it..

My friend recently had an issue with his 4g cutting out. Airplane mode being toggled on and off seem to bring it back, but only for a short amount of time. Finally found a thread on VZW forum of people having the same issue. I'll link to it when I find it again...
Come to find out it was the sim card. Got a replacement and had solid 4g with no cut outs. Unfortunately my friends G2 screen died the next day so he couldn't reap the benefits lol

Hey guys- I'm having this same issue, on my D801 with CM10.2 and DarkPA (tried both). Started yesterday evening - my phone automatically switches back to GSM/WCDMA preferred no matter what I pick. It's only picking up 3G/H+. I'm in the Chicago area.
I called TMobile and they gave me some BS about it being my tower, but also software issue, etc etc. The guy was just saying things. Still no luck. I am going to go to the TMo store today to see if a new SIM card will fix it.
EDIT: Turns out the cell tower near me is just being strange. I can walk down the street and get LTE, but when I walk towards my apartment the LTE dies and switches to 3G/H+. Weird.
Hi, thanks for replies. I got my 4G overtime. Happened to my brother as well. He waited 2 weeks before getting 4G. And btw, is H H+?

[Q] LG G2 D800 AT&T voice calls drop 4GLTE to 4G

Hi guys I searched the forums and didn't see any mention of this besides somebody with a Sprint version of the phone talking about it. I bought an AT&T G2 D800 over the phone with them, they shipped it to me and it was fine for a day or so until AT&T rolled out the D80010o firmware then my phone started getting strange battery drains and in call volume setting keeps reverting back to 90% every time I reset the phone, so I brought it in and exchanged it for a new one. Herein lies the problem.
On this new G2, I noticed that every time I would go to make a call, the signal drops down from 4GLTE to just regular 4G. That never happened to the phone I brought in to exchange. Granted I don't remember making a call before I did the firmware update so I can't say for sure if it did it before the software update but I doubt it since the notes on AT&T's site said it was mainly making the phone ISIS capable. The reason I noticed the difference right away was because up until that point I'd never seen the 4G icon on the G2, so I saw it right away. I was still in my car testing the phone so I came back into the store to ask them if that was normal, they said it was. One guy even said it happens to his iPhone too. Since there was 3 of them saying it was normal, I walked back out. I went home and did some more research and it seems like the G2 supports "LTE (SVLTE, CSFB, CA, VoLTE, RCS, MIMO)" taken from: www lg com/global/g2/sub3 html (sorry it won't let me post outside links) and also like I said, my previous G2 didn't do that.
I need help confirming from other AT&T LG G2 D800 owners that their phone doesn't do the same thing, that when you make a voice call in an area where you're getting 4GLTE, the radio doesn't drop down to just regular 4G. The minute I hang up it goes back up to 4GLTE and I'm staying still in one spot so it's coverage, and my entire has always had LTE coverage. Please let me know before I bring it in for another exchange as the AT&T I went to the customer service was terribad, I'd like to go in there with certainty so that if push comes to shove, I'll just tell them to open a new G2 and test it on the spot to see if it does that. Any help would be much appreciated, thank you.
Confirmed on the 4GLTE -> 4G on voice call -> 4GLTE.
Never paid attention b4 and don't know whether it supposed to be that way or not.
And yes, with the D80010o firmware, battery seems to drop quicker than expected
Thanks for the quick response and apparently being the only LG G2 D800 owner on this forum. Yeah I haven't updated this phone yet and battery once again runs like a champ.

Your phone will drop to 4G until VoLTE (voice over LTE) rolls out possibly next year. It's been like this for a while, so don't think there is something wrong with the device.

I know this is a bit off topic but is there a separate 4G LTE icon in the notification (status) bar? All my other phones have had the 4G LTE icon there when I'm at home but this phone always says 4G
You guy the software of lg g2 if really bad your phone does not know when to change to 3g 4g or 4lte its not just att is all lg g2 the update is supposed to fix it but that wont happened as you can see. Try to update prifile and prl to see if it help.... mines its fine now after i update
And if you are using a custom rom you may have to do this http://forum.xda-developers.com/showthread.php?t=2569237

Nope, there isn't. The 4GLTE disappears the the 4G icon replaces it at the same spot or vice versa. I'd try turning off the phone for a while and then turning it back on, or swap out the SIM. The guy at my AT&T store told me sometimes it's an activation thing where it can take a day or two to be "fully" activated and get full 4GLTE.

Thanks... not quite sure what you're talking about with the link though but I'm on AT&T... AT&T/T-Mobile are GSM and don't have PRLs to update... that's a CDMA Verizon/Sprint thing.
