No network connection after hard factory reset? - LG Optimus 2x

OK folks, so here is the story, concise and to the point.
1. Bought new LG Optimus 2X (white edition) from eBay, locked to Spanish network
2. Unlocked phone to accept a T-Mobile SIM card using code purchased from internet
3. Phoned worked OK, except for Google Navigation (GN). Using GPS Test app, I could 'see' 5 - 8 satellites and eventually it did lock to 2 - 4 of those, but immediately thereafter when I launched GN, the phone did nothing and just sat there thinking and 'searching'...
4. To fix the above, I tried a hard factory reset. This made things worse as now I don't even have an internet connection. Whether it is Google Play or a browser, it simply says "no connection" (although it works OK if wi-fi enabled)
My WIRELESS & NETWORKS settings look like this:
Data enabled - checked
Data roaming - unchecked
Network mode - GSM / WCDMA (auto mode)
Network operators --> Search networks --> do I ask it to select a network automatically or shall I select T-Mobile UMTS or T-Mobile GSM?
Any idea what else could be wrong / I am missing? Internet, Google Play and Gmail did work, but they no longer do after I hard reset. I am sure I have an incorrect configuration, maybe the phone by default is trying to get to the net via the Spanish carrier it was originally locked to?

first try to get flash to the Stock ROM through Smartflash method....or check for Homero's work in the Developer's section and you will get root access, custom ROM and CWM (which is the most important for flashing ROMs, Kernels etc)....and then check for the Baseband.
First I would suggest that you need to flash the STOCK ROM through Smartflash method....please follow HOMERO's thread and instructions....will let you know the following things later....else you might end up confused
Thanks

A1rforceOne m8 have u tried checking the APN.May be due to hard reset u might have erased you network provider APN settings.Just check it.

[Q] [SOLVED] Can't Get Data (3g) need help

PROBLEM SOLVED - DEFECTIVE SIM CARD. Thanks everybody !!!
Hi guys,
I really need your help with this one, here's the deal :
1. just bought my second SGS from vodaphone CH last week.
2. the phone came with 2.1 stock
3. i was not able to get data connection (able to make phonecalls and sms, but no 3g)
4. my apn settings are correct (i have another sgs configured same way on same network)
5. decided to upgrade to 2.2 (JPH) hoped this would help - NO
6. updated MODEM & CSC to the SAME ones working on my second SGS - STILL NOT WORKING
what else could it be ???
THANK YOU FOR YOUR HELP
did you install DroidWall ?
Nope,
Never heard of that Apo.
Can it help ?

Here's what's there, can you see what is wrong ?
Try this, worked for me
This is a weird coincidence. I have (had!) the exact same problem.
My problem was when I reflashed my galaxy S with stock firmware back again, I lost 3g connection. Using a different sim (which supports only Edge) I was able to get edge connection but with my sim, there was no connection.
Here's what I did. It seems when you select the band selection to "Automatic" it somehow didnt get registered properly even though it showed up on the settings->Wireless and network->Mobile networks->NetworkMode. Even though it read GSM/WCDMA (auto mode) it wasnt actually the case.
So - type *#2263# on your phone to enter the Service Mode's Band Selection.
There see if first row is [1] AUTOMATIC[] OR [1] AUTOMATIC[*]
In my case it wasnt selected ie. there was no *. So I clicked on it and did that selection myself and baam!! H connection. It connected even before I exited from service mode.
I tried a 2g and 3g card after that multiple times and it connects properly to E or H from then on.
Give it a try. I am hoping that your APN is set properly.
Anup
Thanks for the help, but unfortunately this didn't work :-(
1. Automatic was selected.
2. Ive tried to play around with the options there and within the mobile networks.
Nothing works ... this is so frustrating :-(

Why didn't you just call Vodafone and get their help before flashing the phone If you already have another SGS configured same way at the same location with 3G, then chances are there is a hardware problem with the phone.
Anyways, try contacting vodafone, they might still do something about it (despite the fact you have voided their warranty by flashing).

[Q] Help!!! Lost Carrier Signal after Factory Data Reset but Detects Other Carriers

Hi:
Searched the threads but didn't find a solution to my problem.
I have two identical Galaxy S i9000T phones with the same firmware. Both were working fine but I performed a factory data reset to one of them in order to remove the primary sync account. This reset was performed via the privacy menu, NOT the CWM 3-button combo. After that, I LOST my carrier's signal. I can see other carriers while doing a network operator search, but NOT my specific carrier. I must add that sometimes I was able to get signal from my carrier and even make calls and use 3G internet, but most of the time I was getting a "No signal.." or similar message
Now the facts:
Phone model: Galaxy i9000T
Carrier: Claro Puerto Rico
Firmware: Rooted Android 2.3.3 PDA:XWJVB Phone:XXJVK CSC:XEE_JV3 Remember the other phone is working fine with this same fw
Operator's Detected: ATT, T-Mobile
Can't make phone calls, not use internet. Wi-Fi is fully functional
Tried the following:
Reset with CWM by 3 button combo - Not worked
Re-install ROM - Not worked
*#2263# to select carriers frequency - Not worked
Installed a XXJPU modem - Not worked (stopped seeing carrier at all after this)
Compared most of the internal settings with the *#*#197328640#*#* between both phones - Didn't Worked
Any suggestion will be highly appreciated.
Thanks!!!
Enter settings for network manually .
jje
Thanks!!! I know how to configure the APN settings. Don't have a clue of how to configure network settings manually. I'm searching this forum but got so many results it will take me a while to find this info.
Could you provide a quick answer or point me to a thread?
Ask network for settings enter via settings wireless and network mobile networks .
jje
Ohh. That was it. Tried that, didn't worked either. If I try searching for network operators, it only detects T-Mobile and AT&T, not Claro. That's why I suspect is something modem or frequency related. Also when checking with *#0011#, it's always fixed at WDCMA 1900 while the working phone has it at WDCMA 850. No matter what I change it remains locked at 1900.
Thanks for your support and patience with me.

[Q] Cynogenmod on Verizon; SMS and data work, but no voice

Now that you fine folks got s-off working on version 4.4.2 for the HTC One, I was able to put Cyanogenmod on it today. Things seem to work okay, except for the one glaring issue: I can't use the phone to make or get calls. If I look at Settings->About Phone->Status, I get this:
Network - Verizon Wireless
Mobile network type - LTE
Service state - Voiceut of Service / Data: In Service
Roaming - Not roaming
Mobile network state - Disconnected
I suspect that I might have the wrong "Mobile networks" settings in the Settings->Wireless & Networks->More section. For the Preferred network type, I selected "GSM/WCDMA/LTE", but I've tried a few others with no positive effects. For System Select, I'm set to Home Only. If I try to search for available networks, it returns an error and doesn't find any.
Any ideas? Thanks!
I was reading more into this, and people on Sprint found this issue when using Cyanogenmod last summer. I don't know if a solution was found, but the workaround was switching the network type to CDMA only, and then switching "back." The "back" is the key for me (I hope). What should it be set to? I don't remember what it was before I started messing around. It may have been global, but I tried that to no avail. Does anyone have a minute to pop into their settings and check? Thanks!

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]

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.

Data problem on Int. Roaming (Brazilian carrier on Canada)

Hi everyone! I recently had a problem with my phone (hard brick on Moto G 2014) while traveling in Canada and had to buy my device locally. After some research I saw that the nexus 6 (XT1103) works fine in Brazil and with our carriers.
I set up the device just fine, upgraded to M and my SIM Card (carrier is VIVO from Brazil) is recognized normally with functional call and SMS, but no data on International Roaming. I checked the APN and looks fine, also tried to reset APNs, configure manually and even wipe data, but no luck. I try to connect and it shows the ! signal on mobile icon, and even shows that some KB of data was used in the process (currently data usage shows 0.12, and it increases every time I activate Data and Roaming).
And finally, I tried to "input the code *#*#4636#*#* on dialer > phone info > set preferred network type as LTE only" as I saw in some places and also didn't work.
----------------
What did work though, while I was writing this post, was changing "set preferred network type" as GSM only.
Is this normal? Or is there anything that I can do to use as LTE or to have this working automatically without the need of changing phone options to GSM only?
And to finish, if any brazilian see this post and had a similar experience, it would be good to know your experience with International Roaming and local data usage (especially if you use VIVO).
Thanks and sorry for long post.
