4G no longer appears/works - Sony Xperia Z Ultra

Hi Guys and Girls,
After finally managing to get through the whole noobie learning how to root/backup/flash etc, I noticed later on that 4G no longer appears, checking through the network operators and network mode, non of them mention it, only 3G
This was active and working before I did the changes, so am a little puzzled. Also I noticed I was receiving text messages from Vodaphone regarding updates etc, but I receive non now.. so not sure if that's also linked?
Phone details are
C6833
4.4.2
Kernel 3.4.0 Jackie
14.3.A.0.757
Would be grateful for the support to get this back, not sure if I can simply call my network provider and ask for some sort of update to be resent?

Hello.
Watch in settings if 4G/LTE is selected or prefered.

Hi,
I used to have the option for 4G and a network from vodaphone for 4G
Now I only have the LTE preferred option

I can't help you, sorry.
Maybe a problem with ROM or kernel you use.
You can change ROM, kernel, or full wipe your phone if you want te get 4G and other users can't help.

4g = lte

How come no symbols show up now to let you know what your connected to, when I selected LTE to start, at the moment I selected it, the connection broke then re-connected and LTE appeared but now it even shows? is that normal? 4G showed at all times so I know the coverage is fine.
Am just worried as this is my first android and my first experience performing the rooting and updates etc, and has been a stress lol

[Q] Problem: Accidently selected USA Band!

I recently got an unlocked AT&T Atrix off eBay. I was mucking around with the *#*#4636#*#* menu trying to fix a minor connectivity problem where I couldn't connect via UMTS, and by the chain of unfortunate events I managed to set the frequency to USA band. Now, since there is only USA band to select, I can't set it to any other band, I am in Australia and only pick up 2 other networks which are not mine.
Is there anything I can do to get it back to the unlocked state so I can find my network?
I remember with my Galaxy S, there was a recovery mode that could wipe everything, is there anything like that with the Atrix?
Thanks in advance!
I don't mean to sound asinine but can't you just do the same thing and select the correct information?
You could also do a full reset on the device or flash it too.
No, only the USA band is there, I cannot select anything else It came unlocked already so I'm not sure how they did it.
I'm hoping there is a way to fix this without resetting or flashing it.
If it comes down to it, is this the most up to date flashing guide? http://forum.xda-developers.com/showthread.php?t=991072
Thanks again!

Select Android Recovery
Click right bottom of screen
Wipe out
Then you are all clean
If your phone is rooted, you can manually input the proper carrier information in
settings > wireless & networks > mobile networks > access point names
A quick google search or call to your provider should be able to get you the information you need to enable data
On the other hand, the AT&T Atrix doesn't support UMTS 1700/2100, so if that's the band your carriers run on, you're SOL trying to get 3G.

actually the AT&T atrix supports 850/1900/2100 UMTS bands so it does work for overseas carriers that support 2100
im actually using it right now in Hong Kong and they use the 2100 band for 3G, no problems with data at all
apparently the OTA update fixed your issue with the USA band for some people who had the problem. i think they did as follows flash to the retail sbf, than let everything stock, get the update over wifi install it and the radio worked again.

No this method doesn't work ..
I was in a similar situation 2 days ago. So, the first thing i tried was do a Android recovery. After this method failing, I went to the last stop, Flashing of the 4.1.26 SBF.
And I jumped with joy to see my Atrix seeing the GSM signal again.
I had 3G before this had happened so I know it worked on my network.
So just follow this guide and I will have my GSM signal back again?

Flashed it back to stock, now it's working

Assuming you are using Telstra (same as me) have you used the mobile configuration page? Support the ATRIX
configure.telstra.com.au/telstra/index.jsp
It might, but requires the phone to be working first, as it SMS a password to gain access ot the site!

Correct, I should have stated it was an intended fix if he hadn't of fiddled with it (i.e. his connectivity issues) as it installs all the correct APNs and settings for you (However it does not add default,tether - just default so be sure to update it for tethering)
you should put [SOLVED] in the title so people know where to look for the same problem ;D
Howzit,
Could you show me how did you do that?
I'm new using andorid and I dont know how to do this procedure.
Thanks.

[Q] Data not working with unlocked Aria on tmobile

I recently unlocked my HTC Aria (Att) and am using it on T-Mobile but it will not connect to the data network i can text and call but not access the internet from tmobiles network. I have been trying to figure out how to make it connect and don't know what to do. I tried setting it up to a new VPN but i don't know if i did it correctly. I am aware that it will only be an edge connection but something is better than nothing. Is there anyone that could help me out?

If you were trying to set up a VPN, that is the wrong option. You need to set up APN settings for T-Mobile. I'm sure if you search you will find the correct settings you need.
So an unlocked Aria's data will work with T-mobile?
Will an unlocked T-mobile device function fully with my AT&T sim card?

Yes to both questions. That's what unlocked means.
The only thing that won't work is 3G data because AT&T and T-Mobile use different frequencies for 3G.
2G data will work fine.

The answer is Yes and No. If your term 'fully' includes 3G data access then no in both cases you will not get 3G data speed. You will only be able to get Edge data, which is pretty slow. So if you need voice and text service and don't mind slow data speeds then go ahead.
Thanks. Well I actually have the problem that I don't get 3G on my Aria for whatever reason .-. Even though I emailed them and they said I should be able to get 3G all I have ever gotten is EDGE. l:
I asked this because I was looking at getting the new Sidekick, but I am seeing if it would be better to just go ahead and switch to T-Mobile, or staying with AT&T and buying an unlocked Sidekick.

Does your Aria have the AT&T logo on the top right? Also, check the model number underneath the battery. If it says A6366 then it should support AT&T 3G frequencies. If it says A6380 then it won't.
How old is your SIM card? You may need a newer one.

I already made a thread for this and couldn't figure out what was wrong, but what was weird was that like 30 mins ago I disconnected from my wifi because I moved my router and stuff, and I was getting G not E, but now that I did it again I am only getting E /:
That was the first time I saw I was getting G
And yes it's an AT&T one, it hasn't been too long since i've had it.
And the under the battery it says A6366

I suspect the "G" you were seeing was for gprs, which if I am not mistaken is slower than edge. Somebody jump in and correct me if I am wrong. If you are running a stock rom, you would see a "3G" not just a "G" if you were actually getting 3G data connection.

G is slower than E. It happens sometimes just because of the nature of wireless networks. Nothing to worry about. When you are getting 3G signal it will say "3G" or "H".
You should really do two things -- first make sure your area actually has 3G. Go to the coverage viewer on AT&T's website, click on "Data" at the top, then see if your area has dark blue ("Mobile Broadband" is what they call 3G on that page). Of course the other way to know is if you have any other AT&T phone that can get 3G signal at your location -- or perhaps a friend's phone.
If you are sure your area actually has 3G coverage, then I'd try going to an AT&T store and asking to switch to a new SIM card. Just explain that you can't get 3G signal on your phone and they should do it for free if the SIM card is old.
Good luck.

[Q] Xperia Z2 US T-Mobile LTE Connection Issue

I've had my Z2 for over a month now but I've been unable to connect to T-Mobile's LTE network here in the US.
I know for a fact there's LTE in my area (I live in Seattle). Other phones have had no problem connecting to LTE.
After talking with T-Mobile's tech support I should have the correct APN settings. They also refreshed my phone on
their network. It helped somewhat. Before they refreshed, I couldn't detect the LTE network. Now I can detect it
but can't connect.
If anyone can give me some advice as to how to get things up and running that would be most helpful.
I've attached some screenshots that may help in diagnosing the problem.
I'm on T-Mobile in Los Angeles, and those are my settings... The only difference I have is the APN protocol is set to IPv6. Not sure if that makes a difference. Otherwise, we have the same exact settings and my LTE works fine.
Call TMo. Sometimes they have to reprovision your phone on the backend. I had that ptoblem with my Z1 but not with Z2. My APN type is blank. The settings can be found at TMo site. If you cannot find them, call TMo and they wipl email that to you.
Sent from my SGP312
Thanks for the suggestions.
I changed to IPv6, IPv4/6; I still get H+ but I dont get LTE.
I did call them, I guess what I meant by refresh was "reprovision". When I first got the Z2 I couldn't even detect LTE with network search.
But after talking with them; I was able to see the network. But for whatever reasons I cannot connect to it.

Might be a stupid question, but are you using an LTE-compatible SIM card?
haha, no that's actually a good question. I wasn't before but I went to t-mobile and got a new lte compatible one. but nothing's changed. i'm thinking maybe there's something wrong with the sim card.
Mine hasn't said "LTE" since I updated to .402 FW. It says 4G now instead, does yours show neither LTE or 4G? I get H+ in some areass, so I know there's a difference between the symbols (even if Tmo likes to think they are both 4G).
Try flash .438 ftf file via flashtool
To see can solve it.
Sent from my D6503 using XDA Free mobile app
I flashed unbranded. 402 ftf from Germany when I first got my device. Then I deleted the factory t-mobile apn that it downloaded and used these settings. They always work for me with unbranded international devices!
2219
The icon im getting is 3G/H+
Singtel .438 didn't work; same problem;
It might be an issue with my baseband.
I have

I'll try flashing germany .402 now.

[Q] LTE not working on Z2?

So around 3 weeks ago I got a brand new unlocked Z2 D6503. As it says, it supports LTE and the bands it support are available and broadcasted here in KSA.
I'm on the operator Zain KSA and when I manually search for mobile networks, I do see the LTE network by the operator but whenever I select it, it doesn't register on it.
I've tried everything from calling/visiting the network operator from changing the SIM and getting a new one.
The FW I have is .314
Anyone has any experience or any idea? Do I need to reflash the FW?
May be enter the correct APN settings for your carrier?

Firstly, are you on an LTE plan? For Singapore, we need to sign up to an LTE plan and the operator has to do the necessary activation, before we can register on the LTE network.

That's the thing, I already had 4G activated, and I specially got it deactivated and activated again on this handset. 4G coverage is in my area, each and everything is in optimal condition. The network operator says everything is also fine at their end...

Yup everything is configured correctly
I can confirm that it is the handset that is not registering LTE.
I just popped in a working LTE SIM which has full coverage in my area and Z2 fails to register it...
Well I can't say much about LTE since I am on 3G data plan so can't use it. But the funny thing happened that I was on Edge connection, even tho I was in city centre and I could use 3G, it was full. So went into phone options and changed into 3G only and then Z2 has magically seen the better connection. Try to do that for LTE, maybe it will work. Otherwise I would flash other firmware or repair with PCC.

Okay so actually solved the issue.
I reinstalled/repaired the FW using Sony PC Companion and now LTE works perfectly. But the side effect? I heard that 4.4.2 causes many bugs and seems like I just got the phone sluggish one.
Phone feels sluggish in different parts as well as when I tap the recent icons button. Also the animation for WiFi turning on and off is not there anymore...
I don't know what's happening anymore....:/
I too have a bit of a lag when I hit recents menu button. I guess it's just the way Z2 is now and we have to wait for new firmwares, hopefully with less bugs, to come.
Happy for you that you fixed the problem with LTE

Yeah, seems like we'll just have to wait for 4.4.4 to hit...
Sad how the animations worked and there was no lag but sadly no LTE functionality. Such bad FW release.
And yeah atleast I fixed the LTE issue as I really can't stand slow internet and H+ seems pretty slow to me.
Same problem...install the new software through PC companion still the problem

E5823 - no 4G (UK)??

purchased an 'EU' z5c from ebay
I was wondering why I cant get 4g signal only H+ when in 4g areas
I have read the only difference between the E5823 and E5803 is the cat 6/cat 4 lte, I dont really know what this means but I assume this might be the problem
4g is set to 'preffered' in network settings menu
network provider is Three
any ideas?
Have you contacted your service provider? might be that you are prioritized to use HSPA, they might have to do a reset on you in their system or just enable 4G etc?

The phone was purchased unlocked and I have been using my Three SIM card in another phone (GS3 LTE) previously and this had 4G signal no problem ... dont see why putting the SIM into a new phone would then change some setting on the network provider's side..
I will contact them anyway
very disappointing I fear maybe this EU version is blocking Uk 4g somehow
thank you
