No 3G Network with I9000XWJG5

Hey,
i flashed the I9000XWJG5 Firmware and now i do not get 3g to work. I used an o2 UK Sim and do net get a data connection (before it was always 3g) and no 3g connection with orange too, just gprs.
Has anyone an idea, what i can do?
--- update ---
also only o2 uk sim is edge where before was 3g.
Made a test with my htc hero (Villainrom 12), same place, same sim card and i got 3g.
and 'only 2g' is NOT activated on the samsung galaxy s

You need to configure your mobile operators' APNs.

it is configured properly. so settings are correct. i am not the only one with the problem. i read it on various threads but couldnt find a post with the solution so far.

You're holding it... wait, no, just manually re-enter the APN settings, because flashing firmware will wipe them out. also try factory reset, if that won't help.
3g will popup immediately when you have put in the correct APN settings. Trust me.

As i said with an htc hero, same settings, it works, with the samsung galaxy it doesnt. so i can assume that the settings are correct
htc hero = 3g
samsung galaxy s = 2g

Could it be you are roaming (you see an R with the reception bars). By default it will not use 3G when roaming. You can turn it on in settings. I have a Dutch Telfort sim and KPN took over Telfort. So i am on the KPN network now and my phone always thinks i am roaming.

Pay as you go or contract? Have you checked the APN entries as they differ on O2.

payasyougo and i changed the the user to payandgo.o2.co.uk also user to payandgo.
works fine in htc hero with 3g, not on samsung galaxy, just 2g

Flashed another Code(CODE_I9000XWJFF) and radio(MODEM_I9000XXJF8.tar) and 3g worked again.
then tried just flash the code (CODE_I9000XWJG5) and it still works. so i guess the radio (MODEM_I9000XXJG1) does not work for my samsung galaxy s properly
when i look now in the settings of 'about phone' i see
baseband version I9000XXJF8 and
Build Number ECLAIR.XWJG5
Does anyone think i will have a problem with that combination?

Need some help with my MotoX - Not registering on my network

Hi Everyone,
I got me a used MotoX, a customized version with a back cover and a badgers logo (go badgers!)
Anyway, it worked fine in the US on At&t, it worked fine in Europe, but now i'm in Israel and i can't get it to work on my network. I tried to put in a friend's SIM from another network and it worked just fine, it's just my company's SIM that does not work -> the SIM is recognized, the device is looking for a signal but fails, and tells me that "No Service | Selected network (GOLAN T) unavailable"
My device is an xt1053
The network is Golan Telecom - (google that for the wikipedia page, xda wouldn't let me post the link cuz i'm a n00b)
I have no idea what could be done, i don't even know where to start looking up this problem, or what should i even be looking for...
Any sort of information that might be remotely helpful would be appreciated!
thanks in advance..

Try entering the APN data manually?

How do i do that? i didn't know that was even possible..

Have you checked what the network mode is set to? Try setting it to automatic.
Settings->Wireless& Networks>More->Mobile Networks

Thanks a lot mate, i did try that. Nothing.
Do you reckon it might be related to the rom installed? i mean, is there a chance that it would work if i install a custom rom?

It's also possible your network might be blocking the phone's IMEI and/or your SIM. Check your sim with another phone. If sim works then check with your network provider on the status the IMEI (and ask them to unblock it if it is indeed blocked by accident).
You can get the number in settings -> About phone -> Status or you can just dial *#06#

Android 5.1.1. Update Disables Mobile Data (D5803)

Hello,
I recently updated my Z3 compact (D5803) to android 5.1.1. on the T-Mobile network here in NYC. Ever since then, I frequently lose the ability to do anything data-based with the phone. No web browing, no chatting on whatsapp. I can still make phone calls and send/receive SMS, however. The data functionality returns when on WiFi, but goes away once I switch back to LTE. In order for me to get data on LTE, I have to manually download the internet settings for my provider to my phone (this is located under the Settings menu in android). Even then, it only lasts for several minutes before the data connection is lost. T-Mobile was unable to fix the problem, and changing the SIM card didn't resolve the issue.
Anyone else experience this?

Yes, many others have the same problem, see various posts in this thread: http://forum.xda-developers.com/z3-compact/general/discussion-5-1-1-stock-released-post-t3162309
Currently, the best workaround seems to be to disable and re-enable mobile data, or to go to airplane mode and back again. That solves the issue until you drop LTE connection the next time, then you will have to re-iterate.

Yes I am having the exact same problem since updating to 5.1.1. As the other reply says turning airplane mode off then on is the quickest way to get connectivity back (swipe down twice from the top for quick access). This is terribly frustrating though, it only lasts for a few minutes. I can't believe they pushed the update with this issue!

My phone had this issue after the over the air update. I reset the phone to factory, wiped all data. Two days on, now, and no more problems with this.

Same problem. I tried factory reset out of desperation, but it didn't work.
Love this phone, but very discouraged by this bug.
(I'm on t-mobile in Seattle, fwiw)

As posted in the other thread, there is now a fix/workaround:
From reddit user FishStik5: Going into the APN settings and changing the APN protocol to iPv4 only (it was iPv6 before) seems to fix the problem.
How to find the setting: Settings-> Wirelessa and Network / more -> Mobile networks -> APN -> T-mobile data -> APN protocol -> Set to IPv4.

Looks like this worked for me (T-mobile, San Francisco area). Thanks for posting this

i'm having the same problem and didn't work for my the ipv4. still loosing data, i have to reboot the phone

I have also problem with that (Orange, Poland). I sent my phone to official Sony service, they reload the software, but I still have that problem. Lte is working for a while and when my phone switches to wcdma (because it is not in a range of lte) it is not working either. However, when I change the preferred network from lte to wcdma it is working without any issues.

Same problem here although I'm on ipv4 [emoji34]
Sent from my Z3 Compact

I thınk you shouldnt buy operator phones. Buy ınternatıonal models next tıme

Mine isn't an operator model, I'm using Straight Talk and also have the issue. It made my phone useless....I almost never have data

This worked for me
This worked on my Doogee Valencia2 Y100Pro
Install and Open app "Hidden Android Settings" (by 0Alex)
Select choose and open "RadioInfo"
Move to Last option "TOGGLE DNS CHECK"
mine read "0.0.0.0 not allowed"
press the "TOGGLE DNS CHECK" so that it displays "0.0.0.0 Allowed"
That's it - my mobile data worked, I hope it works for yo

1. Change "APN Protocol" to IPv4
2. Change "APN Type" to: "default,supl" only
3. Change "APN" to "internet"
4. Save.
Best, Martin.

this is a bug on 5.1.1 sony need to fix it

Any news with this issue?

No problem here with LTE on the CM 12.1 Cyanogenmod flavor of 5.1.1 on T-mobile (that I've noticed at least). But I think CM 12.1 may handle the APN settings differently (mine is set to T-Mobile LTE ipV4) from the stock ROM or it could be something Sony messed up from the AOSP code. I'm NOT suggesting anyone try a CM ROM as a solution as there are lots of downsides to unlocking your phone and flashing any non-stock ROM. But the problem does seem to be specific to the Sony ROM and not 5.1.1 in general.

I also have this problem after the update to 5.1.1 in the Netherlands. The first problem was that the update changed some mobile data settings, so I downloaded the settings from my provider. Unfortunately those settings were also incorrect as I had to manually remove the APN's Proxy and Port (they were set, be needed to be 'not set'/empty). This improved the connection a bit, but it still looses the mobile data at certain places (where the coverage is good). Did a factory reset as the Sony helpdesk suggested. For a few days this seemed to help, but again the same issue came up. The suggested solution mentioned in this thread did not work as those settings are already applied.
I have a profider (Telfort) which uses another provider's network (KPN's). So after the update I also see a annoying R in the signal icon, where in the previous version it always showed H+, H, 3G.
Does anyone know if this is resolved in the new update?

After the last update and a new reconfiguracion on the APN now work correct for me.

Lenovo K3 Note Android Marshmallow Data Connection Error

Hi, I have the Indian version of the Lenovo K3 note (K50a40), and recently installed the official OTA android 6.0 marshmallow update. Everything on the phone appears to be working, including calling and texting (on T-Mobile), except for data connection. Before the update, I would be able to connect to and receive H+ from T-mobile in the USA, but now, even with full bars, the phone lacks data connection. I tried enabling roaming and changing the APN to no avail. Can someone please offer any advice? Any help would be greatly appreciated.

I fixed the issue. for some reason, the update messes up the APN settings. To fix this, google the APN settings for your carrier. Make sure that they are the settings for 4g or LTE. Then, on your device, go to settings>data usage>more>mobile network>access point names>new APN, and enter the information you just looked up. You may need to restart the phone.

No data on AT&T network

Hello everybody,
Since I didn't find straight answer searching this forum I decided to create a new tread.
I have sim unlocked T-mobile LG G4 H811 that I'd like to use in with AT&T. Calls works fine but I don't have any data connection whatsoever. I can see several AT&T networks when I go to Network Operators setting but I'm unable to connect to any of them
So I was wondering if there's a special trick to make it work?
Thanks in advance

I found that going into the cellular network settings and picking 2G then wait for 5seconds and click LTE (recommended) again works. Not sure why this is needed but you would have to do this after every power off of the phone. Very strange hopefully someone gets to the bottom of this issue soon.
