xoom 4g not working - Xoom Q&A, Help & Troubleshooting

Hey everyone,
So i noticed my tablet will no longer connect to LTE. I know i am in a lte area as my D4 has lte service.
I know the tablet sees the lte signal as one of my war driving application will see the different network type.
Anyways does anyone know how to do something like a factory reset of the radios and APN settings.

Oh, i forgot to note, i tried hard resetting the tablet, trying different builds of ICS and even going back to the lte version of HC.
I have put my sim in another 4g device and the device gets 4g just fine

This may sound a little stupid, but did you check your preferred network mode to make sure it was set to LTE/CDMA and not CDMA only?

Yeah, i made sure. I made sure to toggle it to cdma only and back to lte/cdma mode and no dice. I even forced it using the field test menus.
No dice. I see after it sees lte it just kind of sits there. It doesnt indicate it trying to connect or anything, then it drops back to evdo rev a mode

Bump, anyone have any ideas?

Im having the same issue. While I don't have another 4G device to check it with, I used to get a great 4G signal, now nothing.

No 4g with CM7 RC 1?

Hello all I'm new to the rooting and custom ROM community but I'm sure i have the hang of it by now...but my problem is that i am using CM7-RC1 and before this i used CM7 NIGHTLY # 60 and with both i have not been able to use or see a 4g network
As of right now all i have is 1x or E
i have searched the forums and have seen that there are some APN issues but, i have not found any solutions to my problem...
any input would be appreciated.

You dont ever see H? H is the symbol for HSPA+ or 4G which is basically the same (according to t-mobile). If you never see an H then that is odd. Was it a fresh install and did you do a full wipe of your last rom before flashing?
it's no "4G" icon....but it's 4G speed when you see "H"
I like to see 4G icon too
if your seeing 1X thats cdma lol probably simple, i had this problem, do this go to settings, then wireless networks, then mobile network, and then access point names and make sure u see it on tmobile not simple, if it is on simple tap on the dot next to tmobile. then after that back out go to phone hit *#*#4636#*#*, then u will see a menu, go to phone information and scroll down , make sure it is on wcdma preferred.... let me know how u make out buddy
When i installed this ROM i went through ROM manager and cleared cache, delvik cache, wiped data, and back up...so from my knowlege it was a clean install.
I also dont ever see 3g or H or H+ sadly, i want this problem fixed

my bad for the double post but, i have done all the steps here and even tried rebooting the phone and i still get 1x.
Just in case you are wondering before, with the original ROM, i did have 4g signal
I have the "H".

hmmm, do u have an older style simcard? in another words did u take it out of ....lets say a g1 and stick it in the g2x? or did it come with g2x new? cuz older sim cards are having problems with newer phones u would have to grab a new one from tmobile they would give u one for free if that was the case .....also did u skip the sign in process? (google acct) cuz for some reason u cant do that u have to sign in rite away... ok try this first hard reboot, hold vol up and power until it reboots and see what happens if a nogo then also try one more thing go back to settings , wireless networks, mobile networks, then network operators and hit search network like 5 times it might give u an error let it say it then try again then go back to access points and click on tmobile not the dot part on the actual word tmobile and then u should see the list hit your menu and see if theres a reset apn try that then save, also minor thing to try go into ur browser go to setting and delete cache , history, cookies, and form data.

Thnx bro...if the 1st way doesnt work right ill try reinstalling the ROM
Well...im stumped, nothing is working.
i have cleanly reinstalled the ROM and i am still only getting "Edge" and "1x"

Sorry I might be missing something. What is 1x? Isn't that related to CDMA networks?
Yea I'm sure that's what it is but I can't seem to get it to change no matter what I do...I don't know whatelse to try

What I mean is that these are GSM phones, not CDMA (Sprint and Verizon). Is it possible you're roaming on another network, not T-Mobile? Maybe you don't even have 4G signal where you are.
Open your dialpad and dial *#*#4636#*#* then go to phone information. When your phone displays 1x what does it say is your current network, and then look down several lines and what does it say is the network type?
Anyone know does this phone support GSM1x??? It's a technology to allow roaming between GSM and CDMA networks.
Well under network type it says unknown although i am :
Network: T-Mobile
Roaming: Not Roaming
GSM Service: In Service
GPRS: Connected
Network Type: Unknown
I am also under WCDMA only

Googling my fingers off here lol. The only references I can find to 1x have to do with CDMA networks (Sprint and Verizon which the G2X is not compatible with) and GSM1x which seems to have been experimented with about a decade ago as a possible evolution for GSM providers to utilize CDMA technologies or something like that.
Nowadays GSM carriers here (AT&T and T-Mobile) use UMTS/WCDMA for their 3G data whereas Verizon and Sprint use CDMA2000 (which includes CDMA 1x). The 2 technologies are not compatible but GSM1x was designed to be some sort of a bridge between GSM and CDMA2000.
Have you ever had 3G/4G access thru T-Mobile where you live?

Dropped Connection to Network Problem

my phone will drop connection and then not reconnect. no voice, no data. (wifi still works)
what I've tried:
1. Different radios/firmware
2. different roms
3. different preferred network types
4. switching airplane mode on and off
what I haven't tried:
1. different sim
2. calling tmobile for suggestions
What else could cause this problem?
it could be a hardware issue
Hello,
I have the same issue than you !
I am facing issues such as call drop and no 3G data connection in some area in my region since I have 5 signal bar and H letter displayed (HSDPA connection)...
I have found a workaround consisting in:
1 - Switching to GSM Only mode (2G Only)
2 - Desabling Mobile Data Connection
Then it works, I can pass and receive voice call ...
Regards,
Nino
I'm new to the Sensation and having the exact same issue.
Followed the stickies in the Dev section to S-OFF, root and bypass SIM lock and then once the SIM card is inserted I get only GSM and no data.
If you use *#*#4636#*#* in the Dialer and go to Phone Information do you notice that it always switches to WCDMA preferred? I change to GSM/CDMA auto PRL like all my other Android devices (on Rogers Wireless) and it disconnects, reconnects but only for GSM and no data. It sometimes says it's connected to EDGE or HSPA but no icon at the top right and then it reverts back to GSM.
I have also tried flashing virtually every firmware, ensuring that the radio and RILs match (I had an HTC Desire Z so the HTC phones are not new to me entirely). I don't know what else to do. I tried a Bell SIM card and tried all of the same options to no avail.
I really hope someone can figure this out. I don't want to have destroyed a phone that I just bought for my wife. Her Atrix broke and I purchased that outright as well, so this is really killing my wallet. I've been through about 10 Android devices and I wouldn't say I'm a newb, but I really do feel like one right now. This sucks!
Get a new sim from tmo if it's over 2 phones old.

[Q] Only data if on LTE

Hi, I recently changed service provider and upgraded to a nexus 5.
Sadly i have a problem with my data connection. I can only use data if i have LTE covarage not 3g. So basicly LTE works but not 3g.
I have moved my simcard to another phone and then it works, I have also tried another simcard in my phone and that works to...
My service provider is giving me a hard time claiming that it is a hardware fault but i have a hard time believing them since the phone works perfectly when i borrow other simcards.
So i reach out to you to get some more info so that i can convince the service provider to put a technician on the problem and look if there is something wrong on there side.
Is it possible they are right and there is a hardware issue with my phone even though it works with anoter simcard? Any tips on what i can try to fix this problem?
if it works with another sim card in your phone, then its not hardware or software. itll be related to how your provider set up your account.
Go into your device's hidden service menu and check to see if you have LTE only enabled for preferred network.
Download this app: https://play.google.com/store/apps/details?id=com.cellmapper.nexus5fieldtestmode&hl=en
Go to Android Testing Settings
Phone Information
Set your LTE/GSM to get both LTE and 3G Data.

OP never mentioned that he couldn't make phone calls, only data only works while on LTE. Worth a shot to try it out, and if it's set to LTE/GSM already it might be hardware related.

truth, maybe he never tried calling.
Probably APN. If you're on Sprint the APN bearer has to be set for EHRPD instead of LTE I think.

[Q] Nexus 5 only connects to LTE on T-Mobile

I did some searching around and found a couple of pages with ideas but they have not worked so far. Here's the deal, my son's said his Nexus 5 was getting pretty bad reception so I took a look at it. After some toggling of the network settings I discovered that it will only connect to LTE, not to HSPA(+) or Edge. Where we are, we have somewhat weak LTE (2 of the three towers have been "modernized" with LTE and band 2 HSPA+, one has not and it's slightly closer to us). We have a Cell-Fi repeater so we get strong HSPA+ signal in our house. His sim works fine in a Nexus 4 with the hybrid radio getting Edge, HSPA+ and LTE. My nano sim with adapter that works fine in the Nexus 4 exhibits the same problems in the Nexus 5. I tried formatting the cache from the stock recovery menu and am now looking to do a factory reset since I never did oem unlock this phone so I can't just flash a radio to test.
My gut tells me it's hardware so I have my son rebuilding his phone environment on the Nexus 4 so that we can do a factory reset to see if that helps and I'll unlock it at that point. If it doesn't fix it, I've already started the conversation with the play store. My question is, anyone else seen anything like this? Anything else I should try out?

if lte is in your area, and not a perfect signal, itll still choose to connect to lte by default. if you lose your lte connection, then itll connect to H or 3G, and so on. if you do not want it to connect to lte, go to the phones main settings, mobile networks, then change the preferred network type from lte to 3G. or you can dial *#*#4636#*#*, chose phone info, then change the network type to wcdma preferred.

Thanks for the reply, I understand all that. I don't know if I asked clearly enough or not but the problem we are seeing here is that this particular phone can only connect to LTE which is weak inside my house. So, when it tries to switch over, it just won't connect. I also tried to make a call which will switch to HSPA+ and that too fails. Going to the info menu and selecting WCDMA preferred nets me a phone that won't connect, selecting GSM results in the same. LTE only or GSM/LTE works only if it picks up an LTE signal. Ditto for selecting 2G, 3G or LTE preferred in the Mobile Networks menu. I've also reset the APN's, confirmed that the settings match my MotoX, etc and still no joy.
Just looking for ideas that someone might have that I can try before blowing away all my son's data on a factory reset or, if that fails, hardware replacement.

ok, i understand now. i didnt know that it wasnt connecting to h or 3G when it should. to me it sounds like a device ready to get an rma. i mean there is a hardware mod that could possibly fix it, but its not worth the trouble. if you can get an rma, get an rma.

Yea, according to the nice person I spoke to at the play store, I should indeed qualify for an RMA and I should find out in the next day or so. I purchased the phone new in box from someone and they were able to find the phone and they are now attributing the phone to me.
I am curious about the hardware mod though. Is this just for Edge/HSPA or is it for signal in general? If it's signal in general then I'm not sure I'd want to try it since this phone used to work just fine.

No LTE in some ROMs

Hello. My issue is that my phone won't connect to LTE in stock ROM, but it connects with CM 12.1. But my main "concern" is that it used to connect to LTE using stock ROM... To make the long story short: when I bought the phone, it only connected to H, even if I selected LTE in Preferred Network Type (selecting LTE there even made, and still makes my data connection unstable, getting disconnected and rapidly connecting to data network, but only uses H network type) so I selected 3G, because it was made my connection stable.
Then, after some time, I decided to try and select LTE again, and it connected to LTE! Good, fast, stable connection. But after some weeks, I had to wipe my data partition, and again... it would't grab LTE. Some days ago, I flashed CM ROM, and I was surprised that it grabbed LTE with it again. And today, I decided to flash stock ROM again because CM gave me some problems with moto apps (I had to wipe data because it entered in a bootloop), and again, no LTE in stock ROM.
My question is, what can be causing this behavior? I didn't do anything to purposely fix data connection and use LTE, and my phone is capable of connecting to my carrier LTE band (i tested the speed when I was on LTE and yes, it was a lot faster than H), so it should be some ROM/software related issue. I tried to reset APN setting, connecting to the 2 APN that my phone has, and still won't get LTE.
Any ideas of what could be causing this behavior? Thanks!

dial *#*#4636#*#* and service menu will appear. in phone info menu select network type 'LTE only' and check your signal strength. if it's low like 1 bar in status bar that's why it keeps switching back to HSPA.
I won't connect if I select LTE only, it just shows "no service". But I have good signal here in my house, as I used to have LTE when this was working fine.

maybe carrier signal problems? you should check LTE signal strength on other's phone and compare with yours when it's available at your house.
and you mentioned it was working with cm12.1, try with it again or maybe ur harware was defected

Ok, I'll try again with CM again, but it used to work some time with stock too. I think it shouldn't be a carrier or signal related problem, but I'll try using my sim card in other phone, and try again with CM, I'll report back here after I test.
It seems to be caused because of the APN. I inserted another sim card to my phone and it added a new APN, and it changed the Network Type in phone info to "LTE/GSM Auto (PRL)" and now it works! Thanks for the idea!
But I still find it strange that it connected in CM from the start, hahaha
