Is there a way to turn off 4G LTE and just use 3G without using a ROM? I don't consume much power while at work so I don't really need LTE draining my battery all day but I don't want to turn off the phone.
Anyone?

I was speaking hypothetically. I don't think there is a rom for it, but Im sure there is a way to do it through the settings. Doing a search didn't give me the answer.

I'm not sure if all the versions have this option in settings. I know the tmo rom doesn't while the att rom (rogers base) does.
Go into settings > wireless and networks > more settings > network > mobile networks > network mode, and choose the second option.(GSM/HSPA)

Hey all.
I am on wanamlite 2.7 and perseus 32.1
I have recently activated 3g on my phone.
I am on airtel which is a gsm carrier but 3g runs on wcdma only if I am correct.
Now the problem is I get 0 signals if I select wcdma only or 2g if I select gsm only. Now how can I select gsm for mobile network and wcdma for 3g. In auto mode I get almost 0 signals. It is very annoying to change it every time.

You can't select dual mode like for mobile 2G and for data 3G
WCDAMA only is 3G only
GSM only is 2G only
Auto mode mode means your device will get connected to 3G whenever there is 3G network available, in case you are in area where 3G is not available it will connect to 2G.
when you are selecting WCDMA and not getting signal that suggest there is no 3G network available in your area.
it is advisable to keep Auto. so whenever there is 3g available you will get connect to it, and you can see 3G on status bar, when there is active data sync going on, it will be changed to H/H+
while whenever there is only 2G network available you can see E symbol in status bar.
If you have issue with Auto mode, then just try selecting network manually.
K thanks dr.
But the main prb is I am in my room.
If I select wcdma only then it connects to 3g otherwise in auto mode it stays in 2g mode.
Sent from my GT-N7100 using xda app-developers app
This can happens with poor netwok, if 3G have very poor signal and 2G having strong sometimes it prefers 2G
while you select WCDMA it forces to select 3G.
I get 1 forth or half signal in auto mode otherwise constantly full in gsm only. Irrespective of any other settings...
Sent from my GT-N7100 using xda app-developers app
you men you getting 1/4 th of 2G while auto, and full while GSM only
OR you are saying 1/4th or half of 3G network?
when you have less signal just check in setting-about phone-status - network type

one more thing, though it have least chance..
if you are using other country ROM, then just try flashing indian ROM modem
you can get it from my stock ROM thread post#6
Ok I am on wanamlite 2.5 and csc indian changed via csc changer app.
If I select auto mode and am on wifi then I will get full signal (the 4 bars I am talking about).
If I select gsm still 4 bars and in wcdma 0 bars or no connection.
If I disable wifi.
In auto I get 4 bars if I am connected to 2g data or edge and e sign.
If it gets 3g signal with 3g or h or h+ sign I get 2 bars.
Edit:
Outdoors I get 4 bars with h+.
But indoors 1 or 2 bars with h+ or h or 3g but 4 bars with e or wifi.
I don't know if it was due to outdoors or wanamlite downgrade or csc change to inu.
Sent from my GT-N7100 using xda app-developers app
Also if I enable wifi I don't get 4 bars untill I reboot or go back and forth from gsm only and auto mode.

That's clearly suggests you have poor network in your room, but having strong network for edge(2g)
Here nothing can be helpful except airtel itself
Changing csc actually do nothing, if you want to try then just flash indian modem, this may be more tuned for our network.
Otherwise just change operator, we Indian have number portability, why to worry.

before flashing i wanna make sure modems are backwards compatible because I am on wanamlite 2.5 ubdll3.
and I don't think the latest modem ma6 was released back then.
so updating only modem is enough ?
and should it be flashed with pda tab only ?
Not released date but modem from india may have some fine tuning for Indian network
Yes download tar file from post i shown you previously and flash with pda tab of odin.
Indian modem will have letter 'dd' that is important.
Latest indian modem is ddlk6

In my country, after certain data is used, speed is then shaped at 384 kbps.
So, i was thinking whether there is a way to force the phone to run on UMTS only.
It will probably save a lot of battery. I saw such function on CM based rom, but I am on Omega rom (sammy based).
Thanks.
I second this question. I use whatsapp as my main form of communication on my phone and have to check emails for work as soon as they come in. I would like to run the phone on the edge network and only activate the 3g stuff when I need it. I am running the stock firmware but I am rooted. Oh and no CWM just stock recovery also. So hope there is a way without haveing to flash something.

lol lucky of you...here in spain when you pass the limit it is reduced to 64kb/s...
well, to the answer, as said switch off autosync and in the data perfiles there is an option to put it in 2g which consumes much less than 3g
hope it helped

Install Simplistic Framework. It will give you a toggle to easily switch between 2g and 3g
Check settings....
Under settings-> mobile networks -> You can change setting from GSM/WCDMA AUTO to GSM only
I use Asylum rom... do not remember much about Omega but its there somewhere in settings.

Actually, you're still connected as 3G, same battery drain, but your operator is just capping your DL and UL speeds :-\...

i have done that in my previous phone, and it significantly improved my battery performance, it may have to do with poor WCDMA coverage in my country, but still, it's worth trying
Hi there,
I bought this device recently, and soon noticed it is quit though to have a decent conversation with it.
Basically after one minute the signal seems lost, I cannot hear properly the other person, then it comes back, then the call hangs up..and so on.
Anyone having any similar experiences with this phone? Is there any way to fix it? Is there anything I could try to do?
Thanks.

Hello,
thanks for replying.
This does mean I would lose the 3G internet speed, doesn't it?
If so, I don't think that it is an option.

Yup,but what happens is whenever 3g n/w is low,its keeps on searching for network,wont switch to 2g that easily,,so I thought that may be ur prob I think

It looks like I can have a decent call with both the settings "GSM only" and "WCDMA only" (with data disabled).
I finished my data allowance for the month and my operator set me a limit of 32k. Could that cause the problem? So there isn't a real device issue?
I have always thought that data and voice had different separated bandwith ranges, speaking in terms of frequency...
Shoot... I lost my data connection all of a sudden.. I was on Vanir ROM... Tried efs restore but still no luck with all aosp/cm custom roms.. I'm only having 3g data working with OptimusDE Rom which is stock based still no LTE.. anyone can help with this situation??

You figure this out yet? Restore your EFS with the same ROM you backed it up in. ie Stock, OpTimuS, nexogen
I'll look at my ESN in I few and see if it is 8 digits. Gotta restore to stock first.

Do you have a stock backup to restore with? Try that. Either way, I'm guessing you're doing the update profile/prl also.
I know 4G/LTE has been giving me issues for a while, so I have to manually turn it on. Sucks, cuz I can get 4G, but my area is too weak to keep it. If I leave 4G on, I'll loose all reception.
On stockish roms, go to Settings>More>Mobile Networks>Network Mode, and select CDMA.
Then try update profile/prl. Maybe it'll work. Although when you update, everything reverts back to 4G if you have it, and you'll have to turn it off again.
Hope that all makes sense. :silly:

For the data? Or LGNPST.
I can't remember for sure, but LGNPST doesn't wipe data. The only thing I can think of to hopefully get your phone working again is to do a Factory reset. You'll have stock recovery now and I'm pretty sure a Factory reset will wipe everything. SD included. So save whatever files you need, then, in the root guide is how to get into stock recovery and how to navigate it. Let's hope this gets your phone working right again.

Yeah. In stock recovery it's called Factory reset. If this doesn't get you going, LGFlashtool might now that your are Factory Stock

You shouldn't need this but just in case. LGFlashtool. http://forum.xda-developers.com/showthread.php?t=2443185
It uses .tot instead of .bin. You should just be able to change the extension on your bin file to .tot. But it does use a different dll. Hopefully it's, it's own DL.

This is really weird. With stock, you should get everything as far as reception. And your EFS seems intact. Maybe Sprint is working, or is having issues with the towers.
I haven't ran LGFlashtool for a long time, but doesn't that give you the Handsfree activation?
You could also try, on stock, Settings>Activate Device. Maybe?
I'm running Blue Lightning, and that's CM based. Try going to Settings>More>Mobile Networks>Preferred Network type and select 3G. See if that works. For me, if I select LTE, and I lose LTE reception, my reception will lock up and I have to either reboot or select 3G and reboot.
I'd say stay on stockish Rom's until you get this figured out. Then move on.
Other than the above, I'm at a loss.

Yes, it ran activation process automatically but no lte even after activation.. I don't think it is tower issue cause my gf's galaxy s3 and mom's note2 having lte in my house.. It is definitely my phone's problem.. Can it be an apn problem? I'd better call and ask sprint about this?
Add. Oh, I also tried cm/asop/aokp based roms, but they not even giving me 3g even though I change preferred network to 3g.. freaking weird.,
