Well I have this SGS4G and I updated it to kd6 and it messed up the network. I almost never got a signal (it would show the circle with a line through it). I flashed it back to KD1 rooted and now it works but it only gets 4G network. Whenever I get out of range of a 4g tower and the phone switches to GSM it gets no network. Is their anyway to fix the radio firmware on this?
Please use the Q&A Forum for questions Thanks

Go to the market and download an app called GPS Aids. Go through the initial set up with it, then under the Tools menu at the top (not the actual menu name, but it's similar), then scroll down the screen until you see an option called Hard Reset. Give that a shot. Bear in mind that you will lose any data you have on the phone when you do it.
Kd6? Never heard of it... Have you tried flashing a different modem?

KD6 would be the gingerbread update. Phone was fixed with a new sims card even though we got a new sims card when it was bought, turns out it was one of the older defective ones

For future reference - KJ6 was the GB update.
Hi fellow Xoom owners.
I'm having this issue with my 3G Xoom that I can't just get past.
As soon as FedEx handed me my internet-ordered tablet, I started looking into rooting methods and all.
Strangely, even though I live in Saudi Arabia, I received it with the US firmware, kernel or whatever it's actually called (MZ600 - XOOM WITH WI-FI + VERIZON 3G Build HRI66) which I didn't know at the time it was Verizon's but was wondering why 3G didn't work.
Anyway, I followed a rooting tutorial without paying attention to the build which got my Xoom stuck into the Moto logo thing.
Following tutorials into how to restore it, I downloaded the right build for Saudi Arabia (MZ601 - XOOM WITH WI-FI + UMTS Build H.6.1-38-9 for Retail Other International) which worked like a charm and with 3G!
Since, at that point I was already out of warranty, I flashed a Tiamat ROM and worked great but without 3G (bummer!).
Going through ROM trials, I'm now on Team EOS Verizon 4G ICS ROM but, as you've already guessed, no 3G for me (duh!).
I noticed that Team EOS are also working on a MZ601 ROM which should have worked to my favor of regaining 3G back but is somwhy isn't.
Bottom line of the story, I want to regain my 3G back while staying on an ICS ROM, preferably Team EOS's .
It's way better than the Honeycomb it came with and I'm not ready to lose all my game save files again!
Please help me.
The Link you provided in you post (Team EOS Verizon 4G ICS ROM)- That Build is not for your Device, as you device is not MZ602 with 4G LTE. Seeing that you received a US MZ600 Xoom that is actually CDMA and not GSM, it is suprising that the MZ601 UMTS worked for you. But since you say that it worked:
Try this one Team EOS ICS, EU 3G Xoom (umts_everest / MZ601)

http://http://goo-inside.me/roms/teameos/gapps/EOS_GApps_ics_4.0.3_v10.5.zip
As Always, If This Was Helpful - Hit The Thanks Button!
I've already tried that ROM and for some reason it did't work.
Though on earlier versions, it used to give me a certain error which goes something like "phone.android.'something' stopped working" but now it doesn't.
As for the build I received it with, I haven'y the slightest idea how that happened!
I even took a picture of of my tablet before rooting in case anything went wrong... here.
Check this thread, you can try out Umts Everest - Euro & also Stingray 3G, as you are having CDMA xoom

Seems promising but gives me the "502 Bad Gateway" BS.
I'll try a bit later or will look for other sources.
EDIT: BTW, since I'm already on ICS, I don't need to factory reset, right?
yea there seems to be an issue with the download links.
its better to do a clean install, you can always backup your apps & data.
Since you brought it, how can I make a backup of my data?
By data I mean game saves 'cuz that's what I can't afford to lose {: s
I wanted to install CM9 on my Galaxy SII but stopped at the same data backup problem.
And, isn't there any tool to use on my PC to backup apps & data and manage my device ROMs... etc?
Titanium backup is one of the best apps to backup data and apps in my experience. You can find it on the play store. Also im not sure if you can buy the pro key for it but it makes reinstalling everything a breeze. Can you still connect to wifi?

@fredrick
RedXXII already gave the answer which i was gonna say. titanium backup is the best, you can backup & restore app + data easily. you just need a rooted device to use titanium backup.
So guys, let me get this straight:
You're saying that an MZ600 Xoom will work on a 900/1800 3g network just by flashing it with a european rom? I thought this was impossible
thread starter himself said that he flashed a 3G rom, which worked for him
I downloaded the right build for Saudi Arabia (MZ601 - XOOM WITH WI-FI + UMTS Build H.6.1-38-9 for Retail Other International) which worked like a charm and with 3G!

that's y its suggested to him to flash euro 3G rom
I have absolutely no idea how this happened.
I bought it from an Arabic online store for use in my country but received with a different ROM.
After restoring my tablet from the Moto logo error, I restored it to the official international firmware and it started working AND with Arabic support!
Maybe seller ordered the wrong software on the right hardware???

Agreed. The electronics involved in GSM and CDMA is definitely different. I think that is why his data never worked in the first place
OK.
I finally found working links for the codename android ROM v1.6.0 and tried the stingray 3G and the umts and none worked.
Any idea on what could be done at this point?
I re-checked the data bearers of both International and European firmwares and they are exactly the same.
Couldn't there be something like a missing driver or so that would make my Xoom recognize the carrier?
Or alternatively, isn't there a way to unlock it to any carrier supporting the same data bearers?
This is puzzling me for some time now. I have an MZ600 (Verizon 3G without the 4g upgrade) but I live in Europe. I know that MZ600 has Qualcomm MDM6600 which supports both cdma and umts. So I thought that using it in Europe would be as easy as switching Team Eos rom from "stingray_cdma / MZ600" to "umts_everest/MZ601" . I had the idea that this would change the baseband and I will manage to register on a 3g (european) network. Sadly, this isn't true and I'm still puzzled whether this is even possible or I haven't found the right way yet.
So to sum things up:
Is Qualcomm MDM6600 capable for both cdma & umts?
Is so, does anyone know someone that managed to get the MZ600 to register on a umts 3g network ?(you may see the signal of 3g but you cannot register)
If anyone can shed some light regarding this issue, it would be nice .
Check product specs for your original country and current place of use.
I believe they have totally different data bearers.
But, who am I to say?
I'm the one with a paradox over here!
so mr. Fredrick Sylar
what version of the xoom do you use...? the MZ600? or the MZ601?
well anyone ......?
have a look at this guys....

Hello,
I have a Verizon Samsung Galaxy S3. I have rooted it about a month ago, and just yesterday switched to the AOKP rom. Everything was working well, except I have run into a couple issues.
1. Won't connect to 4G. I have a 4G data plan, and when I am out somewhere, it won't connect to 4G. Anyone know what to do?
2. I can send picture messages, but when I get them, it says "Download". I click Download, and it just loads with 0% and won't download them.
The biggest issue is the data plan not working, so I really need help with that. Thanks to whoever can help! Majorly appreciated!
-John
Can anyone help? I'm leaving for a trip soon and really need it fixed.
What modem are you running? I had data problems too until I upgraded my modem. I can't post a link yet because of my post count but if you google "verizon galaxy s3 modem" you'll find download links to flashable modems. I'm currently getting the best results with I535VRLK3 in my area. You'll just have to see which one works the best for you personally.
Also check what network you're on (I'm on a TW rom right now, so this might not be the right place to look, but... )
Settings - Wireless and Network - More Settings - Mobile Network. Make sure you're on CDMA/LTE

Also in Access Point Names make sure that you have LTE selected and not EHRPD. Some time it auto switches from LTE to EHRPD. If you notice that you are mostly in 3G it probably switched from LTE to EHRPD, at least that is my experience

Problem:
I have a stock, locked, non-rooted Photon Q, purchased when it launched on Sprint in August 2012. Sprint rolled out LTE in my area (downtown Boston) in roughly February 2013. Since then, this phone has never succesfully connected to, or even detected, a 4G signal.
Android version: 4.0.4
Observations:
Settings > Wireless & networks > More > 4G Status shows "Network Provider: Unavailable" and "IP Address: 0.0.0.0".
##3282# > LTE shows "Enabled: On".
##3282# > LTE is also supposed to have an option to review LTE logs after the first time the phone successfully connects to a 4G network. No such option is visible.
*#*#4636#*#* > Phone Info, ping test shows "Pass" for "ping Hostname" and "HTTP Client test", but for "Ping IpAddr" it shows "Fail: IP addr not reachable". No idea why.
What I've tried:
Obvious stuff. Update PRL, Update Profile, Update Motorola software. Multiple power on/offs, soft resets, hard resets (most recently today).
Sprint tech support (in-store, web chat, phone). Watched them try all the same obvious stuff I tried. Their best idea was to order a replacement phone, and to tell me to call Motorola.
Motorola tech support (phone). They punted, saying the most advanced option they could offer is the hard reset I've already tried. (Seriously? "Level 2" tech support punts after a hard reset?)
A somewhat similar issue was described here: http://forum.xda-developers.com/showthread.php?t=2230107. However, that poster had at one time been able to connect via 4g; I have not. (Also, he had used mods; I have not.) In any event, the post didn't give a resolution.
Any guidance would be appreciated.
How good of a 3g connection did u have? Maybe its just choosing the better connection. Good 3g vs bad 4g

i apologize profusely in advance for this question, but since it isn't explicitly mentioned: you do have the device set to CDMA/4G in Settings/More/Mobile Networks/Network Mode? i am also asking because i have mine set to CDMA only, and i have all the exact same settings and readouts that you mentioned. sorry if you do have that set tho..
in any case, did you consider letting them give you a replacement?

Fair questions; no need to apologize! Yes, I have Network Mode set to CDMA/4G.
As for replacement, it's funny: in the same breath with which they suggested a replacement, the Sprint store techs opined that they don't actually think a replacement will fix the problem. Supposedly, this problem has come up with other Photon Qs before, and replacement didn't help. (That begs the question, what did help before, and why didn't it help my particular phone? Whatever.) So, figuring I have nothing to lose, I OK'd the replacement, but I'm continuing to work on the problem myself on the assumption that the replacement won't help.

ah ok, i didn't know some Photon Qs had a problem connecting to LTE. have you scoured the site s4gru.com? i'm not sure it would help, but it is another forum site, and the technical knowledge on that site regarding Sprint LTE is pretty amazing. maybe posting there would be good.
i looked at Boston on the map here, and it definitely looks like you should be picking up LTE!

good luck with the replacement, hopefully that one does work..
What PRL is your phone on??

I'm on 55014. Is there a way to change that? I know very little about how PRLs work.
That prl should work fine. I would check your settings under "mobile networks" then and make sure its set to "LTE/CDMA"
Digiblur posted an awesome thread explaining what a prl does over at s4gru if you are interested. Also you may want to check sensorly to be totally sure there is 4G available where you are.

Sorry if this is a dumb question but have you verified with anyone else that they can connect to LTE? I live near chicago and it was almost 3 weeks after sprint officially said they turned up lte before i saw my phone flip to it for the first time.
Just to close the loop on this: the replacement worked. The new handset both detects and connects to LTE, including in all the places the original handset didn't.
I wish I had more information as to why. The settings all look the same. Maybe this was just a manufacturing QA issue? Bad radio? I suppose I'll never know.
But for anyone else who finds this thread after experiencing the same issue -- don't listen to the Sprint techs if they tell you a replacement won't fix the problem.
Hi all
I see a notification popping up a few times a day (on the left of my shade) with a picture of cellular bars and a question mark next to it. If I click it, it asks if I want to sign into 'home'. Since this is my first GSM phone, I wasn't sure if this was a
KitKat Issue
APN Issue
Carrier Issue
Something else
I apologize in advance if this is some commonly known GSM thing and easy to resolve, but this is new to me. I poked around on Google before posting to make sure this wasn't super obvious. Attached are two screenshots. If it helps, I have straight talk as my MVNO for ATT. Thank you all!

Is it a WiFi network named "home" that your phone has found, and is prompting you to connect to it if you can?

Nope. There are no SSID's with the name home. Also, the icon looks distinctly cellular and not WiFi (see original attachments and see if you agree)

I'm in the same boat as you -- ATT on Straight Talk, first GSM phone (Nexus 5) and I noticed this very same thing this morning too and wondered what it was about.
For me it just started today.
Hope there's someone out there that can tell us.
I'm on a T-Mobile family plan and it happens to me too all the time, I just clear the notification and nothing happens, I still have service when it comes up though.

I had a GNex & Nexus 4 on StraightTalk & I never saw that. I've had my Nexus 5 for a week & a half and I never saw it until yesterday. Now I have seen it twice in the last 24 hours. It is something new...
I just started seeing this also. FWIW I'm on Straight Talk (AT&T) also.
I'm getting it also. Straight Talk AT&T LTE SIM. Pressing the Notification takes me to google.com in chrome

I found this thread:

To sum up, several ppl were having this issue with N4 on Net10 and then Straight Talk. One guy says toggling Airplane Mode fixed it for him.
Also here:
http://forum.xda-developers.com/showthread.php?t=2219588
No solution in this thread.
I also saw this one my Straight Talk LTE Nexus 5.
Interesting...
The APN I was using was an ATT one that was on my phone when I first got it. I had modified it with the ST settings.
I created a new APN and entered only the specified fields from:
http://www.straighttalkbyop.com/program.php
Then I selected this new APN as active, and deleted the old APN. Toggled Airplane Mode to reconnect to the network.
The "Sign into network" warning hasn't popped up since. I was getting it every 10 mins or so.
Update
Nevermind... As soon as I left work (and presumably changed towers) the notification was back.
It doesn't actually seem to cause any problems for me but it is weird...

I've had my N5 since Nov 4th and only started seeing this a few days ago. Never saw this with my N4 or my GNex. The N4 went to my wife after I got the N5 and she hasn't seen it happen on the N4. I just upgraded the N4 to KitKat last night and am interested to see if it starts happening. We're both on Straight Talk, though I have a LTE SIM (APN = tfdata) and she has the old one (APN = att.mvno). On another note, my daughter has an iPhone 5 (LTE SIM) which used to show "HOME" as the network. It very recently started showing "TFW", which I assume is "TracFone Wireless". The same happens if I put my SIM in the iPhone. Not sure if these things are related, but both changes occurred very recently.
EDIT: This behavior does not seem to occur when using a "real" AT&T SIM.
I'm having the same issue. Hopefully someone will post a solution soon.
For future readers of this thread, I have not received any more notifications. I did not change anything on my phone, so I assume it was an issue at the provider level (Straight Talk).
I can confirm that for me on Straight Talk this was wrong APN setting. I was missing MMS port and that was enough to trigger this warning. I believe the phone tries to check for new MMS or something and login fails without port, which triggers this message. Since I changed the APN to the same settings posted by embhorn couple of weeks ago, no question mark.

Hello ... Greetings to all. I just wanted to ask a related solutions to these problems? Because at this time I experience it. I wonder what causes it, but I think this is the problem of the provider APN settings. Currently I'm using CM11 Custom ROM. But, strangely I didn't experience this problem when I was on the stock ROM. I beg enlightenment, hopefully someone can help. As seen in my post here. Because the thread for my device section nothing is peeling this problem. Thanks In Advance.
Regards.
The "?" mark sign next to signal strength signifies the SIM card has not activated yet, so you might need to register through internet(Sign in to home from notification) or talk to Customer care.
