My LG G3 will not get service - Android Q&A, Help & Troubleshooting

Hi Guys,
I am new to this I am after a little help with my LG G3 D855.
I brought this second hand and then found out it has no service and after trying different things over time I gave up on it and have been using an S5 but I would like to try and get working. I am a novice at this.
My phones problem.
It seems to recognize the sim because with no sim it tells you.
I have tried several #* combinations to unlock phone etc but nothing works.
When I checked the IMEI number it tells me the phone came from Germany and I am located in New Zealand and I think this may be the issue? (phone is not blacklisted)
Phone info.
Andriod version: 5
Kernel version 3.4.0
Software version V21a-eur-XX
Everything else works fine on phone including wifi just no service?
Any help would be appreciated.
Thank you

[Q] Help! Seemingly unlocked SGSII does not work with all networks?

Hi,
I'm new to both this forum and android, just switched from iphone and already running into the same dead end that I was trying to avoid. Hope to get some suggestions on solutions before trying sell it off again...
I bought a second hand SGSII which is from the UK (T-mobile), and with the help of my brother who has a SGSII and have been on android for a while, I debranded/rooted changed ROM, Kernel and Modem firmware. Before doing this I noted that it did not work with the network I am on but it did with another (both Swedish). After rooting etc I tried again, still does not work (I've tried several sims from my provider, none of them work, still only the other provider). I tried using the Sim Unlock app on Market but it is of no use: It DOES NOT ASK for a sim unlock code on start up. In fact, the unlock app worked and gave me such a code but I cannot use it. Also, I tried plugging in the code using a few of the call codes but it was of no use. And when I put *#SIMLOCK# into the phone dialer everything says 'off'.
Does anyone have any idea of what to do? I cannot go back to Samsung as I do not have a receipt. I hate to think that I have to end my use of Android before it ever started but I have searched my problem for days on end and neither me nor my brother can think of anything.
Any help most appreciated!
Cheers Matt

I am confused did you buy an unlocked phone . If not did you get it unlocked .

JJEgan - sorry if I was unclear. I do not actually know for sure, but as I have never seen the screen on startup where it asks for the unlock code I suspect that it must have been. It now - same as it has been for as long as I have had it - works only with one network which has nothing to do with T-mobile (on which is was originally).
I only know of one way of unlocking, i.e. the unlock app on Market. If there are others I would be very interested!
Phone may require you to enter the networks APN settings manually .
You may not have the correct CSC file for your network for automatic connection ,

Hi - been busy the last few days and unable to try getting the phone to work. I cannot enter the APN settings (which should only have to do with internet?) as I cannot connect to any network in the list - I get "unable to select network". I've tried multiple official firmwares with both only NEE (Nordic) CSC and multi-CSC (where I chose NEE) and none work. Any other ideas?
Cheers

[Q] Can't seem to fully reflash SG Note 2 with stock ROM. Help please!

Hi, and firstly, thanks to any and all who offer their knowledge to assist my conundrum.
I recently purchased a Bell Canada version of the SG Note 2 (i317), I am on Telus so I attempted to Unlock the phone. I looked online and found people were having success unlocking these phones for free using the *#197327640# method, (whereby you go into the service mode, turn off the PERSHO_256 and then INITIALLIZ).
I tried this method and the phone then seemed to work with my telus sim, but only for voice, not data. When I put in a Bell SIM from a friend, both voice and data worked fine - which tells me its not a hardware (radio) issue. I also tried using another friends Telus SIM and had the same results as mine - which tells me it's not a SIM error. Also, all the settings in the mobile network area appeared to be correctly set up.
So, my next step was to try and reflash the phone to the stock Bell ROM and then just buy an Unlock code. I downloaded the stock ROM (2 different ones actually) and used Odin 3.07 to reload the ROM. I've tried it several times now, with both Bell ROMs and each time it says it's been successful, but the phone remains in the same, partially unlocked state.
It seems as though by using the PERSHO_256 method I have permanently, PARTIALLY unlocked the phone. I can't seem to re-lock it by installing the stock Bell ROM, and since it's unlocked, I can't get the foreign SIM error to come up to enable me to put in my purchased unlock code.
If anyone has any insights, it would be GREATLY appreciated. Thanks!

You should ask questions about a specific device in its own Q&A. (unless it doesn't have one). Cuz people there have the same phone and will know exactly what to do.
LIFE! IT'S WHAT YOU MAKE OUT OF IT!
Will do, thanks for the tip!

[Q] Phone settings say g900f but odin says g900t

Hi Guys,
2 months ago I bought a Samsung s5 in Hong Kong.
While travelling through South East Asia this device worked fine.
While traveling through New Zealand (Old home) this phone worked fine.
While traveling through America (New Home) this phone worked fine for the first 2 weeks (on the metroPCS network).
The problem:
Randomly after 2 weeks the s5 stopped connecting to the metroPCS mobile network even though the network was available (btw metroPCS uses the T-Mobile network). It gives errors such as network not available or cannot register with network.
Things I have tried:
-Im sure the APN settings of the phone have not changed and I have double checked to see if they are correct.
-replacing the sim card with another does not fix the issue
-soft and hard reset of the phone does not fix the issue
-Getting metroPCS to refresh the service on this number does not fix the issue
Other important info:
-This phone was purchased in hong kong but it is from the Philippians according to Kies's firmware information (XTC is the country code)
-It is running a custom allianceROM that must have been installed by someone in hongkong
-The device is rooted (superuser app installed)
-the model number as shown in settings is g900f BUT when attempting to flash with odin the phone displays g900t and fails to flash the latest Philippians verison of kit-kat
I have 2 questions:
1. Any ideas why my network connection has suddenly self destructed (and how to fix)?
2. Would flashing a stock ROM to my s5 help? and if so why is there conflicting information on which model I own (g900t/g900f)?
Please help. I do have some know how on flashing android devices but i've really hit the wall on this one guys!
Cheers,

It's not uncommon for the model # to be different with a custom rom as that is a very easy thing to edit in the build.prop. It should tell you under the battery which one it is. As far as the network issues, check to see if the baseband and IMEI are still there and not listed as unknown or incorrectly. It's possible you could get away with flashing the appropriate modem that matches with your update and that might work better in this region vs the previous one.
Please list the Alliance rom version and baseband version here in case it's relevant to your issue.
More info
Im not sure if this helps but looking through the build.prop file in the system folder my ro.product.local.region=GB
When in recovery mode the region is set to XTC (Philippians) using mutli-csc.
Also my IMEI number seems ok and is NOT blocked.
Cheers. Yetti :cyclops:
Baseband and rom etc
Thankls for your reply!
Sorry when you say "under the battery symbol" do you mean in /odins boot script on the device/ or /in settings on the phone/?
Baseband is g900TUVU1ANCH
Build Num: AllianceROM_G900F_XXU1ANCF
If the "no network" issue can be solved with the current firmware that would be the most desirable solution but going through the flashing process may be a good idea for my learning process, and will help with future updates.
Do you think getting back to a stock rom would help me?
tHANKS AGAIN!:cyclops:
Model confirmed to be g900t
Sorry i didn't understand the "under the battery" thing. I was lost in software world. The sticker under the physical battery says SM-900T so i guess that confirms that it is a t-moble verison (and the baseband is therefore correct).
I will try to flash the T-Mobile stock image to the phone and see if that works.
Also i will try to flash a modem (after i work out which one i need).
Cheers, Yetti :cyclops:
Current status.
Flashed the stock T-Mobile firmware to the phone. No success.
Flashed new modem to the phone. No success.
Will go to the T-Mobile store tomorrow to see if they can help (I doubt it but i have to exhaust all the options).
Any more help would be appreciated...
cheers, yetti:cyclops:
By under the battery I mean like to take off the battery cover of the phone and pull the battery out and look at the sticker found there.
G900t.

Click to expand...
Click to collapse
Yep it says g900t (see above)
As per flashing a modem. I have heard that it is possible to flash any modem for any version of the s5 to the phone. Some work well and others not so much. I have tried 2 T-Mobile modems (baseband) the G900TU1ANCH and the G900TUVU1BNG3 with no success. Do you have any recommendations for a modem to try (or even a custom ROM that might help?)
Cheers,
Yetti :cyclops:
I know that you mentioned they refreshed the service for your number, but do they have the correct IMEI in the system for your account? Metro makes a big deal about that now and you can't just take your SIM from another phone and pop it in a new one and go like you can with pretty much every other service (Cricket is like this too now).

SIM not working?

Anyone have the issue where the SIM card isn't recognized? I'm on the RR newest ROM and the card isn't being recognized...I'm about to try the stock ROM and see how that goes.
Similar problem
I`m in a similar position I think. However, my phone recognizes the SIM but when checking the SIM-status the mobile radio seems to be off. I can´t change preferred network type, it just jumps back to "TD-SCDMA/GSM/WCDMA/LTE , I get no results when searching for mobile networks and when I use the *#*#4636#*#* - menu the "Turn on radio"-option wont respond. I`m on latest stock firmware and the phone is still displaying IMEI-numbers. I bought my unlocked European version of Oneplus X yesterday on an auction site, the seller has good reputation and he claims that it worked fine for him. I got a new SIM-card today thinking that would have solved the problem, no luck there however. I also did a hard reset and downgraded to an earlier version of a stock firmware and the error is still there. I noticed I had TWRP v.2.8.7.0 blu_spark r5 preinstalled when I bought it, its a custom kernel right? Could something related to the kernel be the root of the problem or the baseband? Any suggestions on what to do next?

Different stock ROMs for Bell vs. Koodo D852 (LG G3 Canada) ...?

Hello everyone, new user here from Montréal, Canada.
I have a LG G3 (D852) which i used for 2 years, always worked great, but suddenly a bad contact on the motherboard made the screen intermittent, so i had to change the board. I ordered a replacement D852 board (actually a D852 sold for parts with broken screen) reassembled the phone with the new board, and once i sim-unlocked it, everything worked fine with the stock rom that was on it. However i did NOT TAKE NOTE of which exact ROM build/version it was!!!!!
The problem was when i restored an old backup from this phone - the IMEI now shows as "0" and i can't connect to Koodo's mobile network. However, the phone DOES see my correct phone number, so i guess it's not a "sim card not detected" issue.
I tried re-flashing different ROMs for the D852 from different carriers, the imei stays 0 and still no service or network detected -- it's kind of tedious to download these huge files and try them all one by one :/ Anyone have any advice on how i can:
- restore the sim card state to working (persist, efs?), and
- Flash a decent OS like Resurrection or LineageOS while keeping the sim card in a working state?
Thanks very much for anyone who can provide some details/assistance!!
