[Q] Unlocked G2 on emergency calls mode only.

Hi all,
This is my case with the hope of getting any help or lead in order to solve my problem:
After a long research I bought an brand new LG D800 already sim unlocked in the US and brought it to my country (Costa Rica). I made sure the frequencies supported by the D800 are the ones used in my country. In fact 2 years ago I bought another phone that uses same frequencies and had had no problems ever.
As soon as getting in my country I placed the SIM card I'm using in my current phone into the G2 and it recognized the signal and connected to the operators network. I started to make and receive calls almost immediately, and also SMS' without issues. So I started to migrate all my data from the current phone into the G2. I used Titanium Backup for this, so I rooted first the phone using the guide I found here, and basically what I did is installed the apps from Google Play and then restored data using Titanium.
After the second day of use suddenly I found out that I wasn't able to make or receive calls since the phone lost connection to the operators network only allowing emergency calls but the signal bars were full (see scren capture). Sometimes when restarting the phone I get "Phone not allowed MM6" message just after the phone tries to connect to the operators network.
Went to the phone company offices and they tried to help me and made some simple tests, without changing anything inside, such as checking Android's network configurations, checking in their system to verify the IMEI wasn't blocked or reported (the IMEI is clean), also checked the sim configuration and after more than 45 minutes they were not able to find anything wrong in their system or with the phone itself. They also made a final test taking a working sim and put it into the G2 and gatting same emergency calls mode, and took my sim from the G2 and put it in another phone and that phone was able to make and receive calls. So they concluded that the phone has a "built-in" configuration or damage that impedes the phone to connect to the network. They finally suggested to ask the seller to apply the waranty, which is not a viable option since I'm not in the US anymore. This G2 is using the stock ROM (see screen captured).
I've been in close contact with the seller, and he had shown interest in this case but unfortunately hasn't been able to provide much support or help to solve the issue. He reports that he has contacted other buyers of this same phone, also sim unlocked by him, and they all are using their G2s normally. Didn't provide where their locations are tough.
My own conclusions here are that the G2 IMEI is not blocked by the phone company, that there is some kind of fault in the phone that when trying to connect to the network, the network doesn't "like" and rejects connection, althought it worked at the begining, and I'm not able to determine if the fault is software or it's in the hardware of the phone.
So I'm trying to understand what my options are at this moment:
Try to return the phone to the seller, or ask an LG representative in my country to change the unit. Which seems to be very difficult.
Reflash the unit with a stock ROM and reestablish the warranty. But being unsure if this will solve the issue.
Reflash the unit with a new ROM and loose the warranty, and again, being unsure the issue will be solved.
I'm really frustrated and at this moment and have no idea on what to do.
Any ideas or insight will be appreciated.
Thanks.
NOTE: I reinitialized the unit and lost any signal (see screenshots) but received update notifications from Google Play and was able to upload the screenshots into my Dropbox although no signal is shown in the status bar and no WiFi connection is established, only data connection thru APN (I Assume).

Go into status, what's IMEI say?
Sounds like EFS issues. I take it you didn't back it up after setting up on carrier and flashing?
Of so, you have some manual work to do with diag mode and a couple apps via pc.

Hi Steamer;
Under status I see 3 items:
1) Phone Number: shows"Unknown".
2) IMEI: shows the number printed on the box, on a sticker on phone's back.
3) IMEI SV: shows"03".
Where can I learn more about EFS issues? Are there tutorials?
As you say I haven't done any backup thing.

Hi again Steamer:
After reading quite a bit about EFS issues now I understand much better what you meant with your post.
And as you said I didn't back up efs folder, I even didn't flash any ROM yet in the unit. The only thing I did was a 'hard reset' to the unit using the Power + Vol. Down method, after having several 'com.android.phone' errors due to backing up data from Titanium.
The phone went to factory state, I put the sim card and everything went back to normal again, meaning that I was able to make and receive calls. Like 4 hours later the phone went to emergency calls only mode, and from then on I'm not able to take it out of that mode.
So I wonder if the efs folder could corrupt after that factory reset. Is it possible?
Thanks again and any light is greatly appreciated.

It is not in its own partition on this device, but in system. A hard reset shouldn't have caused corruption, but it is not impossible. Your IMEI is intact then, that is good. From what you said about it working partially, your EFS is most likely fine as well. There is a thread here to get files with custom recovery zip file, or you can use adb commands to do it yourself. I don't have guides off hand, but Google is your friend, just specified this phone in searches. Try a new SIM. Sounds more like SIM /carrier issue now as you are out of "activation". That is why emergency is popped and unknown number. The SIM itself may and most likely is bad(or carrier has an issue with your account), in turn it can't communicate with the server causing non activation on network search. Priority to SIM.

I had the same issues. Bought in Us using now in India. Go to settings..tethering&networks.. mobile networks... international data roaming and select standard data. Switch off and switch on your phone .
This will happen when you use, internet over gsm. If you disable internet or if your phone loses signal while switching between edge and 3g/4g data, this is tend to happen.

Similar Problem
I have an lg vs980 and I was using it with H2O wireless and later I changed to Simple Mobile. I'm living in Puerto Rico. The phone was working all right and, suddenly, one day it was always displaying 'emergency calls only'.
I did factory reset, then I reflashed stock lollipop and it was like nothing happened, keeps displaying 'emergency calls only'.
Then I found this post http://forum.xda-developers.com/show....php?t=2394689 and applied the patch but didn't seem to resolve the problem.
As a last resort I tried flashing cm 12.1 and before first boot applied the patch from the cited thread but no result, keeps displaying 'emergency calls only'.
Has anyone found a solution to this problem?

[Q] LG G2 Automatically Rejecting Calls - Sleep Mode, Call Reject - Disabled

Members,
I've never been a fan of LG and the issues that I'm getting into with G2 seems to be never ending.
The most nerving one is this:
Complete factory reset and use phone for 10-15hrs
Then calls would automatically start getting rejected
Quiet Mode is switched off, Block Incoming Calls is disabled
Call Reject is Turned off
Still when the number is called, the phone's display would come up, but there won't be any notification. The call would get rejected after 1 ring.
No 3rd party application is installed, heck, even Google account is not configured.
Anyone in the same boat or any advise to solve this?
Tx

I am also facing the same issue. I am completely stock, rooted.

Problem Solution?
I am also having the issue. Did you find the solution?

Same problem here
After first unlock LG LS980, it shows vodafone network and all working fine. But Data Connection was not running. After then doing some tweaks and installing some patches and resetting and adding VPN, etc.. It shows Data Connection. Now Data Connection is working perfectly but all incoming calls are rejected automtically.
Have you found any solution?
If any one can help then would appreciate a lot..
Thanks.

Same probelm
I have an LG G2 D802 32GB from Germany. Installed custom ROM and then flashed to the stock ROM. Then I found out that there is 10GB only. Tried your method and flashed by LG Mobile Support Tool to Android 5 from 4.4.2. Still 10 GB. I don't think that deleting 2 partitions (there was a post who fixed it by this) will be a good idea.

Not getting connectivity on LG G2 VS980

Hi guys,
I am new here. Initially I had my vs980(verizon) LG G2 on official android 4.4(kitkat) and used a t mobile sim(but I never used to get 4g internet. I used to get HSPA(3g)internet but I had to reboot each time to use it,2g internet worked fine) and I could call and send messages.
My problem
And then something weird happened. I couldnt get any connectivity at all. It says that I have connected to a 4g network, but when I try to call the connectivity dissappears. I can recieve messages, but message sending fails. I cant recieve or send calls.
Solutions I tried
1. Tried my friends T mobile SIM on mine. Same issue ( But my SIM works normally on his phone)
2. Installed official 39a lollipop from verizon. Same issue
3. Installed T-mobile ROM lollipop which I found on xda here . Same issue persists, but I can at least use wifi calling now.
Any idea on what the issue might be? Or any solution?

Do I need to try flashing a different modem or something?
Or could this be a hardware issue? since it failed across different roms(official/unofficial)
If its a hardware issue, any idea what parts should be replaced?

Radio issue NO 3G?

Hey guys,
I've been fighting with this all day and its time to ask for opinions.
I recently received my phone back from the repair center to fix some serious cosmetic damage. Before sending it there I verified that everything was working properly.
The problem I am having now is that when I turn on the phone, it connects to LTE. I can SMS and use data briefly.
If I try to make a phone call or after a certain amount of time the mobile network will drop to either "no service" or "emergency calls only".
I have tried factory reset, clearing cache, original factory radio/bootloader, new factory radio/bootloader, N preview. No change.
Any help would be greatly appreciated.

Try this settings , other networks, mobile networks, network type change that to 3g then back to lte see if that helps

If I put it on 3G it only shows "no service" or "emergency calls only". I tested my SIM in another phone and it works fine.

Have you changed any settings in the secret dialer menu? I had this same issue and that's where my problem originated. Installing Chroma rom fixed it for me. I was able to switch Roms afterwards without issues.

*#*#4636#*#*? I have that set to the same as my other phone.

I haven't installed any non stock ROMs. I'm going to install chroma and see if it helps. Otherwise I wonder if they damaged the antenna during repair.

So I tried...
Flashing stock radio
Flashing original factory ROM
Flashing Chroma
Restoring. No success...
To make the problem even more interesting.... I inserted a different SIM (Rogers) I'm on Bell and it worked briefly. Got a new SIM from Bell, no good...
Any other ideas?

Calls not working, DATA & SMS working. Always on LTE.

Hey guys, quick queston.
Calls are not working. When you dial out it just shows Dialing.. If trying to Dial in it shows Busy.
DATA, SMS, Network is working. If you make Emergency call without Sim card inserted it connects.
Can this problem be solved?

Happened to me last night.
Tried clearing phone app cache. Tried rebooting. Tried clearing cache in TWRP. Tried reflashing current ROM. Tried reflashing older version of current ROM. Nothing worked.
Finally tried restoring a backup I made (I THINK it was w/ TWRP 3.0.2-1). That bricked my phone.
Have ONLY ever been running DU Weeklies, no kernels, no other mods. Never tried N (Previews or otherwise). Just all of a sudden, couldn't make or recieve calls.
No idea what happened, and with all these bootloops from ppl going from MM to N and back, my concerns get lost in the wash. So heads up, no warning within 12 hours of not making calls and it just "dialing", I now have an expensive desk ornament.

I noticed the same problem. What network are you guys on? I'm on project Fi and I noticed it only happened when I was connected to T-mobile band 12. When it switched to a different band or network, calls started working again. Could it be something to do with VoLTE not working correctly?

Well i asked this question because someone is selling a 6p quite cheap with this problem. Did a bit of searching and found out that this problem could be linked to loose Antena contacts, corrupted cache, wrong selected bands radio bands.. The guy who is selling claims that it happened after factory reset. I was hoping to buy it cheap and fix it myself, but since there are no solutions and pointers to what causes this problem, can't buy. That would mean I'm buying a small tablet..

I'm on Sprint.

Have you guys tried going into the "Phone information" section if the *#*#4636#*#* debug screen and seeing which option is selected? It should be "LTE/CDMA auto (PRL)" if you're on Sprint.
