As the the title suggests,
My dad's boss purchased this phone and while it works with any sim you place in it, upon turning the phone on, it basically summarises the following,
You have inserted a USIM that is not part of LG U+, and as such will be data locked.
(not word for word quote)
Now I take this to mean that the phone was carrier locked to Koreas LG U+, but the phone works here, and phone calls, and 3g speeds, but no 4G/LTE.
The current firmware version on it is 4.4.2 with I believe G900LKLU1AND3_G900LLUC1AND3_LUC
Now I've tried many different things to try and fix this;
I've read that 4.3+ version is bootlocked, (not exactly sure what this changes)'
I've tried flashing an Australian SM-G900I firmware (thinking the bands will be fixed, as its a software not hardware issue as far as I can tell)
Upon trying this, Odin throws a failed error, the download mode on the phone freezes, I can reboot it, and it's all good and dandy.
I then looked around and found that its possible to put in a SIM unlock code, however I query how that would work as the sim already works, just not LTE/4G
I tried Chainfires Region Unlocker (yes I know it said only tested on Note 3), which said succeeded, but actually did not enable 4G.
And I also saw a rumour that, if you place a phone call for 5+ minutes it will unlock said phone restrictions. In the phone logs it does show a phone call occurred previously before this phone was purchased, not sure if it was 5 minutes, but this may have been the case.
I'm stumped as to what can be done to flash this phone (or whatever can be done) in order to force it to allow the LTE/4G Networks,
Just to re-cap for the tl;dr,
4G/LTE not connecting as the phone mentions it restricts it due to being a NON-LG U+ SIM upon turning the phone on.
Please help ?

Hi
I also have g900L and had issue with LTE at the beginning But I resolved the issue by the following;
Please dial 319712358 and they will show you a box where you need to enter password then enter 0821.
This will lead you to the hidden menu page where you can find network mode where you can switch it to 4g mode.

I will pass this info on to the guy that owns this phone (my dad's boss) and hopefully all good,
Thanks man ,
Will post back here once I find out if it works on his phone.
Hi, just wanted to let people know I've had this same issue. Bought a G900L online and the network would connect to Optus' 4G/LTE for a few minutes at start up then will automatically go back to 3g. The solution above seems to have allowed my phone to lock to the 4g network.
Thanks

Hi,
I am facing network connectivity issue since the time I entered roaming area on my Matrix 2. It does not connect to network. It keeps showing no network, then for 2 seconds it shows emergency call symbol , then for 2 seconds it gets connected to network and again it keeps showing no network. This cycle keeps on repeating.
I searched for the issue and found that it is issue with atrix 2 software and the suggested solution was to install app called network and choose gsm only from it.
I tried it but it doesn't works for me.
I am able to make a call if I dial number exactly at the moment network appears for 2 seconds.
The only temporary solution I was able to find was to dial self number as soon as network appears and then keep on dialing it for around 8-10 times. Then it gets connected to network for 1/2-1 hour and then again it gets disconnected.
Please let me know if anyone has any solution for it.
I am on JB unrooted and using 2g network.
1) Try another SIM ....
2) try flashing ICS radio.img ...... (you shud know some fastboot commands) search the forum
3) try factory reset or reflash JB ..... it might work sometime
if you are using BSNL ..... then i have my sympathies with you :silly: lol
First off wrong forum, should go here http://forum.xda-developers.com/forumdisplay.php?f=1771
Go back to Stock ICS via RSD Lite 6, try SIM with other phone first and check, do not install apps for network improvement as mostly they just turn radio on & off, in worse case they can botch up some internal default settings. Use this for getting a view on network heat range & in particular tower direction to move towards for better reception https://play.google.com/store/apps/details?id=com.staircase3.opensignal&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5zdGFpcmNhc2UzLm9wZW5zaWduYWwiXQ..
Thanks for the reply...
I have already tried that, its not a network or sim card issue. I have tried inserting sim to other phone and it just works fine.
I put it in general section coz when I googled it I came to know that its an issue with every atrix-2 so every one might have faced this issue while roaming.
Also going back to stock have not worked for anyone. Its an issue with atrix-2 software itself.
You seem to have reached to your own final conclusions but yet please understand on JB 4.1.2 leak there has been no one who has echoed your issue (gps is definitely an issue & for some wifi on some particular bands). Also read this http://forum.xda-developers.com/showthread.php?t=1425560
Try flashing the new 4.2.1 ROM based on official leak of 4.1.2 JB as I believe radio is better on it. On JB leak though one thing I can confirm is when phone enters roaming it automatically shuts data randomly and not always & user has to re-enable it. If all fails, fxz to stock ICS and if under warranty claim your stake.
Thanks...will try when I get back to home.
Although I have not reached to conclusion on my own, I search regarding this in Motorola forums and people facing this issue stated that they tried aall the specified methods. They were getting this issue on all os versions.
Please point me towards a link which illustrates issue same as your on JB 4.1.2 specifically.
Hi! I'm having some mayor problems with my OnePlus One.
For some time I have had problems getting calls and sms when using 4G but it seemed to be a problem with my carrier but 2 weeks ago I dropped my phone and the screen broke so I bought a new screen and replaced it. After that the connection to my carrier dropped randomly and now after trying to fix it in different ways I can't get any connection at all with any carrier !
What I have tried so far:
Factory reset
Reinstalled CM
Put paper under the sim for tighter fit
Turned the radio off and on and restart phone
Change pin code
Replace sim-card
Tried different carriers on my phone (my simcard worked on other phones so it is the OPO that is the problem)
Total restore by fastboot-flashing
Installed OxigenOS 2
Tried all modems from the modem collection on CM and Oxigen.
Retyped the APN by hand
Opened the phone again and checked that all cables are connected well
Tried manualy connect to my carrier under Network Operators
For a short time of maximum 10 seconds I got a 4G connection twice in now 3 days of trying but then it stops working again. It feels like a hardware problem BUT I can see a lot of different carriers under Network Operators but when trying to connect it loads for ever and then says "Can't register to your carrier". I called my carrier and thay said nothing was wrong from their end and when I tried on other phones it worked flawlessly.
I'm really out of ideas now and I don't know where to go from here. I really hope someone of you knows that might be the problem!
Thank you so much!
If imei present you can try mobile phone exchange offer on flip kart like online stores. When this happened to my phone I did it , very easy.
Sometimes opo dont search available network or wont register on any network.
Sulution: go to access point and reset it to default first then go to network and try to search for network n if ur able to search then try ro register manually and if it does not work then go to dialer and dial *#*#4636#*#* then click phone info and select the lte/gsm ato prl mode and then click turn radio off and again tuen it onn then smsc refresh and update ( i dnt remember it correctly) if that dnt help then ur network antena is damaged
As stated I'm using the LG G5 H830 T-Mobile variant. I am getting 4G LTE data connection and everything runs well (Not in any WiFi range) Yet for SMS and calling as well as mobile hotspot I get "No USIM card' error. This happened after wiping the system and formatting data. Rebooted recovery (as per instructions on forum) then installed the stock firmware & Patch with systemless root and xposed. After this I did factor reset when just pulling the sim didn't help. Still nothing. I reflashed just the stock firmware with TWRP and SuperSU and issue is still happening. I've disabled rebooted and enabled the phone radio. SIM is in good condition and tray as well everything is SECURE and should be good to go.
I'm assuming a new SIM might be a solution. But I'm not counting on it and with Labor Day tomorrow for me I wouldn't be able to pick one up for 2 days. So here I am...hoping someone might have a fix. I know I don't have many posts on here. But I am an experienced user....just not with the more basic of problems I guess
Thanks!!
Has anyone else experienced this yet? I'm just curious...I had it fixed for a couple days. I've formatted data and done complete system wipe. Tried it resetting phone with the COMPLETE zip and TOT using LGUP. I'm receiving texts. Not calls. Not able to send either. I've activated new sim, didn't help. LG support just told me to look into warranty. T-Mobile needless to say just wanted. Sim card does show stock tmobile short code contacts but phone number shows as unknown. Hotspot won't work. I've tried setting the phone number to the sim. Nothing.
Anyways. I don't think I messed with anything, even so I've done everything to start the phone from scratch. Going to replace it, just more or less curious at this point and maybe others have had the same issue.
I believe I had the same issue as you and it was driving me crazy. I was constantly wiping data, system, etc but my phone kept giving the message "roaming indicator off" where it should show the name of the carrier. This resulted in me having LTE data and that's it- no 3g, no phone calls, etc. I couldn't even access the mobile network menu.
What ended up causing the issue was the network mode setting under wireless networks. Keep in mind at this point I'm running a patched rom which now gives more options in the network mode menu than the phone came factory with. I have an area at work where I have to switch to 3g, GSM/wcdma preferred network setting, because although I have full LTE signal, my connection goes dead. When switching back from 3g I chose the setting lte/CDMA thinking this would force my phone to stay in lte mode due to another area on an upper floor where the phone will constantly drop lte.
Anyways this resulted in my phone saying roaming indicator unavailable, the inability to make or receive phone calls, and either the mobile networks or network mode menus being grayed out. When stuck in this mode there is no way to put the phone back into the standard "GSM/wcdma/lte" mode. Even a complete reflash won't fix it. I even used lgup, which worked for maybe a day until it force closed the phone app and went back to roaming indicator unavail. I wiped every partition and even reflashed radio firmware. Nothing worked.
What ended up fixing it was using an app called v10 hidden settings which allowed me to access the network mode menu directly and re-choose the lte/wcdma/GSM setting. Incidentally on first access to this menu through the app there are only two network settings available. Once you choose a GSM setting, the rest appear.
I'm not sure if this was your issue but I hoped this helped because this took me about a week to workout.
I bought a s7 930v with a cracked screen which i replaced. I did a factory reset because the owner couldnt remember pin. When it loaded it said non verizon sim card inserted but couldnt find any networks. Because im in australia i thought that might be the problem so i flashed it to 930u. It all works but still no network. When i look in the settings it says radio off. I cant access any ussd codes so i cant use that to turn it on. What other options do i have? Do i need to root it and use an app or is there a adb code i can use. Please let me know step by step as i am very new to all this. TIA
Hi,
I have a g930p running g930u Nougat firmware. I did an OTA update to Oreo and was not able to connect to my network after.
I'm in Canada and on Public Mobile which is owned by Telus.
I can see Telus, Bell, Rogers, and Freedom when I do a manual network search, but cannot connect to any of them.
I did some research, and I'm wondering if there are some issues with MVNO's.
My IMEI is present, so I don't think there is an issue there.
I was able to use Odin to downgrade back to Nougat. Everything works fine on Nougat.
I tried manually flashing the latest g930u oreo firmware after, and no luck. A factory reset did not help either.
Any ideas?
Thanks!
Same Issue here
Hello,
I seem to have a very similar issue.
Ever since the most recent update (to Oreo 8.0.0) my Samsung Galaxy S7 will not connect to mobile networks. The network symbol shows full four bars most of the time (sometimes the crossed out circle), however never indicators for mobile internet. I don't receive texts or whatsapp messages, neither can I send them, the browser says I'm offline. I can't be called and when trying to make calls, after a split second I get a prompt "Not registered on network" and the call ends.
Internet usage works just fine when using Wifi.
Also, the issue only occurs on default network settings: When I go to settings->connections->mobile networks->network mode and select "2G only", the phone functions as I would expect it to do. All other modes don't work.
Things I've tried without any form of success:
Flight mode on/off
Several reboots
Wiping the cache
Manually searching for network operators (keeps on scanning forever)
Resetting network settings
Resetting my phone to factory settings
Unfortunately I can't cross check my SIM-card with other phones or other SIM cards on my device. Since I've been using both for almost 2 years now, however, I don't think those are the issue.
Device: Samsung Galaxy S7 32GB
Android Version: 8.0.0
Product Code: SM-G930FZKADBT
Baseband version: G930FXXU2ERGC
Build number: R16NW.G930FXXU2ERGE
Network Provider: Mobilcom debitel (Via D2 network, Germany)
I really hope somebody has an idea for a solution, this unnecessary issue renders the phone mostly unusable :/
Hi
A UK user here, I have been experiencing some of the same issues that you have both mentioned. For me however periodically my phone will stop recieving network signal from my phone operator '3' and have completely no signal. This has been happening for a few months now and has happened since the last major update. In attempting to solve the issue, I often reset my phone multiple times to no avail and I simply have to wait until the phone starts to recieve signal again! Very frustrating!
I am not using any type of custom OS currently (or ever previously) and that was my main motivation to join this site, to jailbreak my phone and see if I can overcome these issues through custom fireware or alternatively installing older firmware where this problem did not exist.
The problem is widespread, a simple google of the issue or a visit to the Samsumg forum and you'll find plenty of users reporting the same problem, however Samsung seems to be doing nothing about it. Honestly, I am disgusted! I paid a lot of this phone on its release two years ago and I have simply been forgetten about and no one seems to care at Samsung to provide a solution or any information at all.
Best,
