[Q] Having Signal Issues with UK GSM Galaxy Nexus on TMO Network

I've been reading this forum for the past two days trying to see if there is a similar thread with this issue. Please point me in the right direction if there is a similar thread resolving this issue (this forum is colossal!).
I recently bought a UK version GSM Galaxy Nexus running Modaco 4.0.2 Ir8. I'm using it on T-Mobile's network (The GN is replacing my HTC Sensation).
The gentleman that sold it to me had already unlocked, rooted, and flashed it with Modaco. It works blazing fast. The only thing is that when ever I make a phone call it literally drops in less than 5 minutes. The signal seems to be switching like crazy from 3G to HSPA+ as well.
I've called TMO and they have no clue what the issue is (4 different reps told me 4 different things from needing to factory reset to the towers being down etc.).
Again the phone works great besides the fact that I can't make a phone call for more than a couple of minutes before it drops.
Has anyone seen this with their GN? Is it the phone? The Mod? Are T-Mobile's towers not able to pick up this phone's radios because it's from the UK?
How can I go about fixing this (Factory reset? etc.)? I'm literally about to factory reset this thing this morning when I get home from work.
I don't really have too much experience as far as rooting goes but willing to learn and get this issue resolved.

What radio version are you using?
I'm on T-Mobile and xxkk6 works well for me.
If you don't know what you have, I suggest u go to the dev section and start reading for a while

xxkk6 at the least should be on there. i think there is xxkl7 possibly. the xxkk6 is the stock radio, but if there is a kk7 or kl7 might want to try that as it would be a later version.

How can I tell which radio version I'm on and does it give me the option to switch it?

I was using KK1 before and it was absolutely fine until about a week ago, then I started to get dropped calls etc.

I'm on xxk1. How do I switch to kk6?

Thanks for sending me that link. Which baseband set up would be good for the US (NYC specifically). They all look like they are designed for European areas.
And once I put in my Sim card, why didn't the phone just figure out with Radioband to attach itself to?

Basebands beginning with UG are for north America. I think there are a couple of threads in the dev section about UG basebands, it might be worth have a look at those.

Thanks for the link. After reading through a couple of pages I'm starting to realize that I have no idea what the hell is going on with switching radio bands. Even worse, I have not read about any instances where one or the other will work very well in NYC (my area).
Is there a grid which shows which radio band is for which area? Anyone know of anywhere that shows the step by way to do this?

I appreciate that. Will be looking into it later this morning when I get off work.
For anyone who had to do this process: Is this a normal thing when rooting and flashing, to have to find a better baseband etc.? Is it because my phone is a UK version that TMO is having an issue dropping my calls?
And lastly, anyone know what the best baseband/radio is suitable for NYC? And why doesn't the phone just figure out which is the best baseband?

the baseband should work. it's gsm, the world standard. but i'm guessing since i don't know exactly what is tweaked, but that the specific baseband for your region will bias your phone for the known networks. ugkk7 works great for me. atnt. i think there is a ugkl6 or 7. sometimes you have to test them. some will work better for others. some will work great and not eat battery. if it eats battery, try another one. i think samsung is decent about releasing different radios for different regions. it can be confusing. now when it's comes to updating their roms, that is a different story.

Ok,
The baseband def has to be affecting my battery. I'm getting not even 10 hours on a full charge from moderate use.
I don't really know exactly what the first owner did to it, only what he told me.
My plan is to bring it back to factory settings (found an article about how to restore the GSM version, but have yet to find any youtube videos abou it....I only see LTE videos on rooting and unrooting, and I'm not sure if it's the same process so I'm not touching those).
If that doesn't help it then I'll go about flashing and changing the baseband.
Again this whole baseband business is really new to me. The input you guys have been giving so far is much appreciated.

Update:
Ended up coming home early from work and staying up all morning trying to figure this out. I decided on using this link first: (http://www.addictivetips.com/mobile/restore-galaxy-nexus-to-stock-how-to/)
to re-lock. That took about 4 hours of troubleshooting and getting to know the lingo and terminology. Then from a combination of other youtube videos I spent another 4 hours trying to figure out how to lock the bootloader. Believe it or not the Xda link about this (http://forum.xda-developers.com/showthread.php?t=1392310) saved me from losing my mind. I literally didn't go to sleep until I made sure I brought the phone back to factory settings.
After I finally got the phone back to factory settings (believe me, it wasn't fun figuring this out especially when I've never rooted before) I noticed the wifi wasn't working, or had a very weak signal. Content with the phone at least being back on factory settings and locked, I go to sleep and wake up today seeing the same issue with the wifi (mean while, I now have good signal/service...didn't even have to mess with the baseband radio config).
I restart the router in our house and power down the phone and restart. Problem fixed.
Not really sure why or how, but bringing the phone back to factory settings seems to make it work just as fast as it worked when Modaco Ir8 4.0.2 was on it. Except now I have amazing Service signal.
I can honestly state that rooting really isn't for me especially with the notion that with every new mod that comes out you have to be flashing on a constant basis. Even though I almost lost my mind trying to figure this out, I would still rather have this approach vs Apple's walled garden approach though. Any day.
One of the reasons I like the Nexus line of phones is that it's pretty much the only Android phone that gets all the updates first and on a constant basis. Which makes it such an awesome phone in that it's also the phone that Google allows any and all capabilities to be customized. I have true respect for all the devs out there who attack this stuff daily.
Just be sure to get enough exercise in and healthy meals along with rest lol.

some people actually recommend factory resetting your device from the get go. i would, but i always just run with the hardware just to make sure the hardware and stress i throw at it will handle all the roms and stuff. and to exchange my phone if finding there is a problem.

Good to hear that you got it sorted out in the end

Rooting/Flashing is great IMO for people who will never have the luxury of getting updates like Nexus phones get. Take control in your own hands on when you decide you want to update(s) etc.
I'm sure any Devs out there (like on this forum) also love tinkering. To each his own.

Indeed. I def learned a lesson: Never let anyone ever root your phone for you. The guy who rooted it for me was nice enough to say I could email him for questions but the more I kept emailing him the more I could tell he was probably getting frustrated at all my worrisome questions ("I'm dropping calls", "Is it because of the rooting?", "My wifi isn't working", "is it because of the rooting?..." etc.).
Just glad to know there are tons of available options for one to seek out help when issues like this arise.

Verizon LTE just quit. Can anyone help diagnose?

Hey everyone...Yesterday, on my stock, 4.0.4 GNex, I noticed I was getting terrible 3G speeds, and no 4G data whatsoever (even though the 4G signal existed). I thought maybe there was a temporary outage, but no dice...VZW support said there were no issues. Today, the issues still remain, and I have no idea what the problem could be. I took some screen shots, so if anyone could offer some advice, I'd really appreciate it. I'd love to try and resolve this myself instead of bringing it to some of the inept VZW techs at the local store. I'm located in Western NY and there is normally a great 4G signal here.
I can post screenshots once I am allowed since I'm a newbie here.
THANKS!
EDIT: I should add, I've experienced the 4G dropping to 3G for a while, and I know this is an ongoing issue with GNex users, but this is completely different.

Another case, same awnser, considering what you said, the device is running the latest official release, and it seems 4g never works at all: return it and get a new one, probably has a bad radio.
If we can get a NYC vzw user as yourself who doesnt have the issues you're describing, i think that would kill it as faulty hardware.

Meaning the radio just went bad? I've had this since launch day and never experienced a problem until yesterday. Also, I'm far from NYC, so if anyone in Western NY (Rochester/Buffalo area) has the same issue, let me know please.

Well, you said you have a stock phone and it doesn't sound like yourself have made any changes to cause this. So, what is it that you want to do? Flash the radio firmware? Root the phone and try different ROMs? Go through all this so in the end you take it to the store anyway? If your description of the problem is accurate, then it does sound like you have a hardware issue. Just take it in and deal with the inept VZW techs.

No I didn't want to do any of the things you listed. I was asking if anyone here could help me diagnose the problem, in other words, see if there's any way to prove it's a hardware issue. I wasn't sure if there were any applications I could get to run diagnostics checks.

If you never experienced these issues before, yes.
I would eliminate a few things (simcard, check another 4g capable phone, side by side, see if it works fine) first and do some testing.

It ended up being the SIM card. They replaced it, and instantly the 4G worked again.

How to Increase Signal in my Apartment?

I recently moved in to a new apartment for college and unfortunately my signal is very poor while inside the building.
This is really the only place on campus that I don't get great signal unless I get close to the window and pray that my phone decides to connect.
I've briefly looked into possible solutions but wanted to see if anyone had any suggestions/opinions on what I should/ could do.
I briefly looked into the Sprint AIRAVE, which I should be able to get. However, unless I can get it for free then I really don't see it as a viable solution, especially since my contract is up soon and I can just move to another carrier.
At this point I see my options being:
1. Get the AIRAVE.
2. Purchase a 3RD party signal booster (If cheaper than Sprint one).
3. Come up with some kind of DIY solution
4. Change some things on my phone in the hope that it improves.
5. Switch to another carrier.
What do you guys suggest doing/ think is the best option?
Are there ay other options I've missed?
Current Setup on my Epic 4g:
Rom: CM9 STABLE build from 8/10
Kernal: Shadow v0.6.3.3
PRL: FC09

I suggest option #1: Call Sprint and throw a fit, and have them provide you an airave

You may be better off with option 5.
The Airave is more of a cop-out solution for Sprint and their craptastic network. However, if it works for you then by all means go with it.
I've been with them for over 10 years now and haven't seen much network improvement in my city in the last 5 years. There are big patches of dead and weak signal spots all over. Hell, I can step outside my office building and find a dead spot in one 5 foot span, then move out of that span and be in a 3-signal strength spot.
I'm waiting a bit longer to see if their network will improve in my area. Otherwise, I will most likely jump carriers.

My family has used them for about 10 years total, with a brief break when we lived in england. I've never really had any problems with getting signal where I needed it before now. But yeah, at this point they better make a good offer if they want me to stay with them.

So I called sprint, they wanted me to go through some troubleshooting stuff and ended up asking me if I was rooted.
I had a bunch of back and forth with him and he claimed that being rooted/not on stock caused my phone to show no "vital signs" and that even if I am using the proper PRL it doesn't matter. Everything he said sounded like a bunch of policy stuff and he never gave a clear explanation of why it mattered if I am rooted. Anyways he said I could restore to stock/factory settings and then he would call me back latter and we would troubleshoot stuff.
I am going to be doing the flowing:
1. Backup everything
2. Odin back to stock (non-rooted + update)
3. Go through the troubleshooting, even though I know it won't make a difference.
4. Hopefully get the AIRAVE for free.
5. Go back to my current setup.
I've also noticed that turning 4G on may actually make a difference in signal (Since there is 4G in atlanta).
Does anyone have in thoughts about this?
Am I wrong in saying that being rooted has NO effect on connectivity?

If you do anything with Sprint that involves troubleshooting, you should be on 100% stock. Also, never admit to rooting, even though there is that PDF from internal Sprint mail around these forums saying it's basically okay for customers to be rooted. It's way easier to just get back on stock and step through troubleshooting, than dealing with a script following CSR on the matter.
It takes an experienced flasher all of 3 minutes to get from stock back to previous setup or a new custom setup. So not a big deal.
Turning on 4G is an entirely different radio; hence you would have differing signal strengths from 4G to 3G.

Maybe try the nexus modem and see if that improves signal. Some people say it has and got rid of dropped calls. Samsung is notorious for making awful modems, but Google made the Nexus one, so it is better for me and most people who have tried it.

I know really shouldn't have admitted to being rooted but I think I kind of wanted to argue with him about it, just to see what kind of reasoning they give.
And yeah, flashing back to my previous setup shouldn't be too hard. I already know for a fact that going to stock won't solve the problem,
I'm still testing the 4G thing since I can't really confirm if it is actually boosting the signal or not.
___________________________________________________________________________________________________________
@xboxfanj: I thought about trying that the other day. I have to be on a CM7 rom to use it, correct?

Now there is a patch for CM10 as well. Nothing yet on stock or CM9.

Yeah I noticed that. I tried switching to PA1.99 and using the nexus modem but it didn't have any kind of effect in my apartment.
So I odined back to stock fc09.
The Sprint rep called me back, I told him it didn't have an effect (because it didn't).
He agreed to send me the AIRAVE at no charge so I should hopefully have it in a week or so.
After I get it all setup I'll update this thread with details as to whether or not it actually solves the problem.
Now time to root my phone again...

Received the AIRAVE today. Took a little bit of fiddling to get it setup right.
I now get pretty consistent signal, generally 5 full bars, throughout my apartment.
My only real complaint is that it decreases my internet download speed from over 100Mb/s to around 40Mb/s.
The decrease is unavoidable since I have to use the AIRAVE router functionality in order to have it and my computer hooked up.
However it did seem to increase my upload speed by about 5Mb/s once I increased the limit it had set by default.
It also seems to causes me to receive texts twice but that may have just been a one off thing.
Overall it has solved the issue and since it was free I can't really complain.

The double text is an occasional thing and probably will never happen again. I hooked my airave to my router instead of the modem as suggested and it works just fine and does not interfere with my throughputs.

This is how I have mine set up and it works perfect.

Mine is setup so that the AIRAVE connects to the wall and then to my laptop (it's probably hooked to a router/modem somewhere but it's dorm internet so I have no control over that).
It would probably be faster if I hooked it through a separate router but I don't really want to spend the money on one, and would need a pretty decent one since my school has one of the top 10 fastest internet connections in the country (if I had to guess number 3, behind the pentagon and google fiber).

[Q] No service @ work. Radio ?s

It seems like I am the only one who doesnt get any service inside of my place of employment. I've asked around and my coworkers with Us Cellular, AT&T, Sprint, even Boost and Cricket all get service. I however, do not get service. Now I work in a major metropolitian city (Chicago's south side to be precise) and I'm right down the way from a major airport (Midway Airport) and as soon as I step outside I get four bars and 4g. I work in a fairly large warehouse, and not near and windows or outside walls. One quick note I forgot to mention. If I go upstairs I am able to get one or two bars in certain places. So anyway, and sorry if this is a dumb question. I've tried doing some research, but working. Mon-Fri 7pm-7am, having a set of 12 month old twins at home, and a wife recovering from foot surgery doesnt leave much free time, lol (Not to mention staying at my inlaws who, get ready for it, have no internet...ugh...). And the info I did find didnt really tell me what I needed to know. And what I need to know is, will flashing a new radio possibly give me service inside work, or will the warehouse walls just be impenetrable no matter what I do? And if theres a thread with my answer in it already, or if this is just a dumb question, please just lemme know so I can take the thread down. Thanks in advance!

There have been people who reported getting signal improvemens with different radios, so id say its worth a shot.
Start with the modem flasher tool as it has about half if our radios bundled up in the one file. Good for testing like you will need to do.
Everything you need is in my modem thread. Its stickied in the development section.

Could also put a cellular repeater in the warehouse
Or connect to a wireless box in the warehouse.

Like the idea, however Looking into it some it appears that repeaters are more than just a little costly so thats pretty much outta the question for me. As for the modem. They aren't particularly accessible so that's really not an option either. I do really appreciate the thought and the ideas though. Thanks.

In your situation, I doubt changing modems will make a difference. But it's easy to try (and free). So, you'd be silly not to try it. Start with LJ4 (if you aren't already using it. You didn't specify your setup). The only other good option is getting on a wifi network. But if it's a big warehouse, that isn't going to cut it, either. Your options are limited, to say the least.

[Q] Samsung note 2

First of all I would like to thank all of you hear that have sound wisdom in dealing with my nightmare. I'm so new to this that my last phone's antennae is still on the top of my care and phone is in it's big carrying bag LOL. I'm 50 years old but am not done trying to learn something new. Here's the problem. I have a note 2 i317 that i bought online from someone. It's build number is jedi xp 9 android 4.1.2 Dernel version 3.0.31 SaberKernel_07+ptmr3 ect ect. So I have little to no signal strength and cannot hook up to the internet. I've called straight talk and spent an hour or two with them as well to no avail. I've been up and down these posts but I'm lost as how to employ some of the things that I have read about. Remember that I'm a noob to the max. I would love someone to put the instructions on how to fix my phone, in plain english that i can understand. I thought I might have a bad sim card as well but don't know how to check it. I've put at least 6 different apn's in and nothing. My old phone worked great in my house now i have this 500 dollars ornament that I can barely even get calls on. PLEASE can someone help me? I would be very grateful to say the least. I've read if you install something wrong that you can brick your device (whatever that means, but it doesn't sound good). I will be anxiously awaiting for the bravest soul to write me back. I say brave cause with me it might take a while. Sorry
Sincerely
Ed

You only 'thought' that you may have a damaged sim card but did you try to change it to a new one?

Would love to help you Ed, need more information on what you mean by 'low signal / cannot connect to internet'. Do you have normal phone service i.e. make calls & send receive texts?
Did the phone ever work at one point, or once you gained possession and tried it, you got the described result? I don't have your AT&T version phone but may be able to help with more info from you.

Is the modem is ur carrier modem?
Have u tried to change the modem to your carrier modem?
Edit : I mean modem+csc

Yes it does work with voice and text messages but no mms and I can't connect to the internet cause of the weak signal I suppose. I haven't tried a new sim card just yet. Installed one that they sent me 5 months ago but when I called them today to activate it was no longer any good. They told me I took too long to activate it and they were sending out another one. As for the signal ...it's very weak. Like one bar two at the most. When we went to oshkosh over the weekend I saw that most everyone was on their cell phone and I couldn't call my kids unless I went searching for an area where my phone would work. I never had this problem before with my other phone that was through straight talk. I spent all day today looking for some more possibilities here and saw that maybe my modem on the phone is no good. I tried to download one and I did but haven't put it into the phone cause I'm scared that I might do it wrong and then the phone will be even more messed up than it is. i believe it's this one i717-ics-ucle2. The guy said it worked good for his straight talk. But if you all think that it's something different then please let me know. Thank you all very much for your time and patience with me. I will definitely try to learn more now that I found this wonderful website.

Hi Ed,
the phone has been modified by the owner who sold it to you. He has changed the software oh the Note2. The Problem is we don't know whether there was any problem in signal for him as well. First check whether the SIM is working fine on any other phone. If it does, then I'm afraid you might have to restore the phone to the original Software to make sure this is not a Hardware issues.

Ed, I'm hoping the links provided to you from other posters has helped. Some of the suggestions have been to try flashing new modems (you're hesitant) and even to install a new ROM. If you have managed to correct your problem, kindly update the thread so other users can benefit from your experience.
If you've had no joy, pursue within the forum for your specific device (AT&T it seems) and good luck!

note 2 problems

Hi all and thanks again for the help you have given me. I just got my new sim card today and it seemed to help. I can get on the internet now but my signal is still only one bar and sometimes not there at all. But at least I can connect via wifi. So the sim was partly to blame. Tweeny...I never said that I wouldn't put another radio or modem on my phone, I'm just not too sure about how to do it just yet. I don't want to ruin my phone anymore than it is. I should just dive into it and see what happens. If anyone else has anymore ideas as to why i have poor reception and also I still can't mms, please let me know. Thank you all once again. I will be a regular visitor here and hopefully one day I can be as confident and resourceful as all of you. God bless you all

Hi ed
i reckon u could read up and try flashing a different modem. beyond that flash a different rom. but u obviously have a lot of reading b4 that. good luck
