[QUESTION] 2G/EDGE on lg nitro hd

i would like to know how can i do to get a 2g networkd "edge"" on lg nitro HD?

Im sure this isn't the only way but probably easiest. Get cm9 and there is an option for it in the settings menu. Works like a charm.

Can't you just put in a 3G apn in ? I believe you can under wireless & networks - more..mobile networks- Access Point Names-hit the search button- new apn and enter one that is for 3G only and click on the one you build as your apn and voila.

From my experience after changing to gsm only and then back to WCDMA preferred i was unable to pick up an LTE signal anymore, requiring to perform the unbrick method to re-aquire LTE connectivity

2G/EDGE only!

Hey everyone! I have a couple of concerns/issues, I have been digging in the forums, on tmobile, etc., I have called my mother and she did say I was special (confirmed Im a loser). Hope you guys can help. I am on the tmobile network, I had an LG G2X (awesome phone), had no problems with root, roms, etc., I just got and unlocked a LG Nitro HD (930) which is from AT&T, I added in the APN for tmobile, which I am able to make calls, text, and get internet, but I can only get 2G/Edge speeds. Does it have to do with the baseband? When I go into the settings I do not have all of the options I had on the G2X to select the network type and so on. I purchased a new phone so that I would not need to renew contract, the phone is better, faster, but slow as a turtle on the internet. I would also like guidance on how to root? There is so much on the LG nitro it is somewhat confusing, I would not want to do anything to ruin the phone. What is the best method, easiest, safest way to root my LG Nitro? I have seen forums with different methods, and so on, the device does not seem to be too root friendly, if one of you experts could provide guidance on how to? best method? what is the best way to load a custom rom, and the best rom out there with good battery life? That would be great. I had CM9 on my G2X and it was great. My phone info is this:
baseband - P930-mdm9220b-v10j-Feb-26-2012-xx1
Kernel v 2.6.35.11
Build GRJ90
Android 2.3.5
Looking at the other post, I thought this would be the best one to post it on.

Hello,
Given the information you have provided about your phones current software you will need to go through the un-brick process in order to downgrade your phones software to a version that can be rooted. Even though your Nitro is not necessarily bricked at the moment the un-brick process will restore your phone to a root able state. I would recommend using mattman86 "[GUIDE] Unbrick, Root, And Install CWM" thread also located in the general section of the Nitro Forum. This guide is a bit easier to follow than others found around here. As a result of the un-bricking process your phone will be rooted. From there I would suggest installing ClockWorkMod recovery and performing a backup of your phone in case you do brick your phone in the future so you will not have to re-do the un-bricking process. As for custom ROM's I would recommend CM9 Stable release. I get awesome battery life with CM9 Stable on my Nitro. As for your data connection, I would try to use a different T-Mobile APN if one exist and see if that works. Hope I could be of help. Click the thanks button if I helped you!

The reason you can't get faster data speeds is because AT&T phones are designed to operate on AT&T's 3G network frequencies, which are not at all compatible with T-Mobile's. Basically, it's impossible to get 3G or faster speeds using the Nitro HD (or any other phone sold by AT&T) on T-Mobile's network, nor will it ever be possible. If data speed is important, you should return the phone now and buy a phone that is intended to be used with T-Mobile instead. (That, or switch providers to AT&T.)

That is correct, you still need to downgrade, your baseband indicates you are on the February update released by LG and you need to downgrade to the original October firmware that came with the nitro when it first shipped.

[Q] Phone won't roam-settings are missing

Hello everyone,
I have a new AT&T plan with five lines, all using Samsung Galaxy S3s, all having the same problem. My 14 day grace period to cancel is almost up and I'm at my wits end searching for an answer. The phones are not rooted as I do not understand most of this technology; however I'm smart enough to know that this is a problem beyond rebooting the phone or resetting the SIM card, as every forum out there is telling people to do. Calling tech support (please don't make me) is a LAST resort for any device I own.
In the town where I work and shop I have no signal at all from AT&T. No voice, text, or data. AT&T coverage map shows "good" coverage in this town. Every so often I do get a weak AT&T signal but only for a few seconds. I do however pick up a very strong signal from a T-Mobile tower. I know that AT&T and T-Mobile both use GSM and should be compatible for roaming purposes, but the phone does not roam; it just shows a strong signal that I cannot connect to. Also, it switches back and forth between these two towers. I posted screen shots taken one minute apart.
In my phone's "Mobile Networks" settings there is no option to chose a network. There are only four options on that page: Mobile Data (checked), Data Roaming (not checked), APN, and Network Operators. I have tried adding a new APN but that did not work. The Network Operators tab says "Default Setup" and I cannot change it. I understand this is an issue with AT&T - they deliberately remove these settings.
I have gone through all the settings in Service Mode using *#197328640# looking for a way to enable the missing settings. I have already used the Service Mode to disable LTE (another setting AT&T likes to deprive us of) but that was not the problem so I put that back on automatic. I have also checked and unchecked every imaginable combo of settings such as wifi, data, airplane mode, etc.
I think the problem is either that the T-Mobile tower is interfering with what *should* be a good AT&T signal, or that the fact that I am "connected" to AT&T (albeit with no bars) is preventing me from roaming. I'd like to know if there is a way to disconnect from AT&T to test that theory. Also, I'd like to know if there is something I can do from Service Mode to enable the missing settings so I can set up roaming.
Thanks so much for any suggestions or help.

Just the default one called "ATT Phone".
I tried a Cingular APN in order to get a better connection to the AT&T tower, but it didn't work and I removed it. I found the T-Mobile APN info and was planning to try that next time I'm in town if I don't find some other solution first.

Is it the wap.cingular or pta one? You have to reboot after changing apn's but I'm sure you already knew that

I used the wap.cingular one and did reboot. Do you think this is an APN issue? I'm kind of at a dead end unless I find where to enable those mobile network settings. Thanks for your responses.

Unfortunately, it didn't work. I also tried to use a T-Mobile one and the phone wouldn't even let me save it.
I broke down and called AT&T tech support to find out where the roaming settings are in the phone... of course they didn't tell me, but they did tell me they don't have a roaming partnership with T-Mobile in my area. Therefore I'm out of luck and will be cancelling my contract.

Galaxy S4 4.4.2 NB4 won't send MMS or receive em =/

I got this phone for my dad, as he had this old crappy phone for years and overpaid for his cell bill every month for minute plan lol i know.
So i got him this Galaxy s4-m919 model to find out that it was upgraded as part of a plan, then the person claimed it they lost it to sell it to another person, and ofc they wouldn't refund me.
So i took another path and came on here to get help, ofc it was a T-mobile phone, so I guess i'm blacklisted on t-mobile networks, but i flashed to 4.3 modem, did sim unlock, then flashed back to 4.2.2.
Put in my new Att sim card, and service has worked ever since, the lame part is now he wants to use MMS, and it keeps on failing to send/receive, when he recieve a mms from someone, it comes up as a huge ass url(you have to click it to see the picture in the browser or w.e, but never ever loads rofl, idk y.)
He doesn't use any apps, he just uses it for calling, internet at times, navigation, wants to use MMS, takes pictures/video, etc. But MMS doesn't work, I ever called the H2O to help me, and they said that i needed to change my "Message Center #" for it to work, seriously? My other phone has "+12063130004", and my dad's is "+13123149810", i think H2O rep wanted me to change it to the # my other phone has which is the first number i listed. Is this really the care? If so, how can I change it? =/

First thing to check, in my opinion, is to see if all the APN options are set correctly. Settings \ Mobile Network \ <more> APN Settings will usually get you there. The ATT APN settings can be found here but you may need to search around if H2O requires different ones. I'm on standard ATT and the settings at that link work for me, with my M919 phone.
Good luck!

I also saw somewhere that you can hook up your phone to the computer and change the Message Center # using Root Explorer(just re-read the post on xda about this and u have to have it rooted =/), then 'SilverEdit' to edit the xml to enter the message center number?( also heard it wasn't permanent either, if u turned it off, or battery died or w.e. it would revert to the previous #, not sure tho) Not sure what to do here. The internet works fine, but H2O rep says i need to change my Message center number to a different one for mms to work. Also tried changing default msging app to hangouts and sending a mms, and it came up with " mobile plan blocks MMS." I also put his sim card into my working phone, and ofc the message center # was the same when i switched it over to my phone and ofc it won't send, says "mms not supported by network, service response error"

Anyone?

Can anyone help me with "Message Center"? My MMS doesn't work, can't send or receive(when i receive an mms, it comes as a big ass url something like "viewmymessage.com/webgui/bla bla/ bla bla/ and so on/", can't open the link on the phone.

If you have AT&T service on a t-mobile phone it needs to be unlocked. He is using it to call people, so I guess it is. You should try flashing an AT&T modem.
Before that, try making your APN type: IPv4 or IPv6. And MM message proxy:0

I'l try that, just put in my H2O settings: APN type: IPv4 or IPv6. And MM message proxy:0; Can't try atm, as for some reason his data went down to 0, even tho he wasn't even using internet for anything on his phone...which was weird. The way I unlocked this phone was flashing the 4.2.2. modem, then went thru "service mode" and did step by step. If the Apn settings you gave, wouldn't work, would flashing the att modem 100% work(got link for the modem, cba to find it atm, last time if flashed it, i used odin)? I'm on 4.4.2 Android version, Baseband: m919uvufnb4.

You're with AT&T on a Tmobile phone right? You should still need to have an AT&T modem. In the slot where it says "APN type", put it as IPv4 and the slot below "APN type", put it as IPv4, also. But non of that is worth trying if you are using AT&T service. You need AT&T modem and APN settings.
Edit: I was watching a movie and read you comment wrong lol. Yes you need to flash AT&T modem and APN

Actually, be careful with this. The modem (which is two parts) has to be paired with the phone model. For example, an M919 can't use the modem from an I337. The Modem runs the radio hardware, which varies by phone. ATT & T-Mo variants have different antennae bands supported, so need somewhat different radios. I'm not sure if trying a different radio will brick anything, but numerous threads have said it doesn't work. The modem consists of the modem.bin (the "GSM Modem") which can be flashed at will, and the non-hlos.bin ("LTE Modem")which needs to be paired with the phone bootloader, or else chaos ensues.
You DO need the right APN settings. Unfortunately, I have no experience with the message center thing... can't help there.

Your phone will still be unlocked regardless. Try to change the APN setting to AT&T first. Like Frankenscript said, both phones have different radios so changing the modem might not work.

I seen people say it works and others say it didn't. Nothing about bricking the phone tho but I do understand what you are saying.

I tried ATT settings, didnt work. I put on H20 settings that were on the site, didn't work. Tried my bros H2O settings that he got from chat rep on their site, then 4G started working, but I keep getting "Mms failed, server error" or w.e. keeps failing, put the H2O internet settings(on), and mms settings. Not sure if his phone is missing something or because his phone is blocked on tmobile's networks, his using H2O meaning his on ATT's network.(i bought him a cheap 1$ mirco-sim, off ebay) Not sure if that plays any role, the calls are good, dats works now, etc, just mms wouldn't work. Suggestions? Some1 on H2Os rep side said it could be the "message center #", that's y it can't be sent or receive or w.e.(His is atts message center #, and its greyed out"

Anyone know how to fix mms problem?(cant receive or send atm, tried a lot of things). Mms keep failing, server error, not supported by network or w.e., lost on wut else to do.

Anyone?

This is the root of your problem, buying stuff from other people, it's probably stolen.
Throw it away and go buy a new phone from Att and this issue will go away.
Somethings fishy here.

Throw it away and go buy a new phone from Att and this issue will go away.
Somethings fishy here.

Cell 4 sale store was selling it, not just a random person. I guess they probably either do it themselves ir buy it from ppl who do it.(upgrade their phone to gs4 or w.e. then claim it lost or stolen, thus keeping their old one and selling the new one) I think they probably flashed it to work for internation, but idk, might've been rooted before 4.4.2, since ota got installed, means root is gone. Anyway to fix the problem instead of just replying with a negative reply? I want to use the phone, calling etc works fine everywhere, 4g is a bit in some places, mms doesnt work at all, one rep at h2o said it might be cuz of message center number, he wanted me to change it to a diff one and see if it solves it or not, but my message center is greyed out.

Apparently there is something wrong with it, at least you should be able to get it replaced for one that works. It could be a build.prop issue. Just guessing.
Pp. Good luck.

Still looking for a solution, anything I could try, to fix Mms to work again?(cant send or receive as it says "server error", failed mms, etc)

[Q] Help with APN settings

I want to start off by saying sorry for posting with a new account, I know that is frowned upon on forums, but I need help with a phone that isn't even mine and I've been trying to figure this out for a week now. I've searched everywhere and I figured it's time to ask the experts. Here's the story.
So my girlfriend got a Samsung Galaxy S3 (previously on T-mobile, model number T999) used and got a Straight Talk plan. I put in an APN for Straight Talk and everything was hunky dory. She didn't like the battery life so I rooted the phone and put cyanogen mod 11 on it (which is really friggin cool, so happy I did that) but it didn't save the APN settings. This is where I'm a dumbass. I didn't write down the settings and I didn't back up the phone (she doesn't have anything on the phone worth restoring, or so I thought, those precious APN settings were there) so now I'm trying to find the new APN settings. Everyone has a different set that worked for them, I can't get any of them to work. I know that the MCC is 310, but I don't know if the MNC is 410, or 260 (I believe it is 260 because that is a T-mobile MNC) if you don't have the proper numbers then it won't even save the APN settings. I have yet to get any settings to actually save which is very frustrating. Any suggestions?

I thought Straight Talk was an AT&T mvno.

I believe it is both. They use towers from Verizon, AT&T and T-Mobile. I think that whatever your phone was on originally is the set of towers that it uses. I've seen APN settings with 410 and 260. IIRC 260 was the MNC that worked before.

There are posts all over xda that have apn settings. Best I can say is to search them out and try them.
It could be a cm issue though. They updated their radio files to work with kk modems and its caused lots of problems for people who have older ones.

Gsm rom only Tmobile AT&T for Sprint phone

I was wondering if its possible to make a gsm rom only for people like us who have a sprint phones unlocked and we only using gsm service such as AT&T and tmobile.

Im ready to buy you $100 whiskey bottle , and im sure there are many of us need rom like this.
Btw stock looking is a preferred
Thanks

yes...the custom recovery works.
but the roms will install but doesnt works perfect. no service

I can work on putting something together
I finally got my two devices unlocked. I can put something together that is geared towards GSM only. The reason they are not working is the framework, buildprop, and mainly the kernel do not use the hardware the correct way. Even though they have gsm capability kernels/ framework from the GSM only devices will not establish connections the same way.

After updating to 6.0.1, the GSM network is more stable. I'm using Att and now LTE and 3G both working perfectly.
I feel now my phone is pretty much as good as stock AT&T phone, except the sprint bloated apps and other sprint stuff. Like voicemail and the ability to dial 611 without jumping to sprint app. I'd love to have stock AT&T ROM and I'm sure others would love to have stock T-Mobile rom and international stock ROM....
This guy did it for sprint note 5

This would be awesome. At the moment I can't even get MMS to work on the g928p on at&t.

APN Settings
SM-G928P on ATT
Name: NXTGENPHONE
APN: NXTGENPHONE
MMSC: http :// mmsc .mobile .att .net (no spaces...xda would kept rejecting it for a url)
MM Proxy: proxy .mobile. att .net (no spaces...xda would kept rejecting it for a url)
MM PORT: 80 (some have experienced better use of 8080)
MCC: 310

I had the same issue till I modified the APN, now it works.
