Need help! The LG g900tm is permanently unlocked. Only 2g works in any of the network modes. Using the g-mon pro program, I found out that the phone detects 3 / 4G, but cannot connect to them. I downgraded the firmware to 10j with a full reset, the phone connected to 4g (range 20), worked for 20 minutes and the network was gone! I tried a SIM card from another operator, but nothing changed. I can't understand what is the reason!
I am in the same situation with my g900tm ..... Did you found any soultion ?
Did anyone find a solution to this issue?? Same situation g900tm.

I have a strange issue, i lost mobile operator network connection
- aeroplane mode on/off does not help
- manual network search finds all mobile operators in range.
- manual selecting my network operator does nothing, it try to connect but finally display “try again latter”
- Change from 4G to 3G does not help
- Eminency call 112 works fine.

That new Galaxy 5? That's probably the issue then, since it's not supposed to be out till April or so. But seriously though, have you made any changes to the system? Custom rom? New radio? Etc? Have you tried your SIM in another phone?

Ok, WAS fine, but what about now?
The problem i write about occures only once on nexus 5.
I have this phone only one day. So it hard to say that sim be all right in ohter phone.
I am on AT&T and have this issue too. My SIM was used fine in Nexus 4 for about 10 months. Never had a loss of network issue, but on Nexus 5 randomly, I seem to lose all network connectivity. Tuning airplane mode on-off, Wi-Fi on-off, 2G-3G- 4G toggle, data on-off, all have no effect. The phone acts like it is on a network, but none of the apps can connect. A reboot fixes it.
I am on stock ROM with Franco kernel.

It is not the same problem, because in my case phone log out from network.
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
Hello everyone!
Yesterday i bought a used Nexus 5 with a problem - it has no signal and the ''Turn on radio'' button doesn't do anything.
The phone recognizes the SIM sard and it shows the correct IMEI.
I have tried flashing different modems but to no avail - it still can't be turned on.
I also can't change the network type, it stays on LTE.
Everything else works fine (Wi-Fi, etc.)
Anyone know what the problem might be? Thanks in advance!
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
Hi,
First of all thank you for having so much of info and help.
I am having a peculiar issue. I own a HTC 816 rooted device. Android 5.0.2. It has been working quite good until I recently connected it with the MirrorLink with my Car's smartlink connectivity. It was initially reluctant to connect and hung once or twice. However, it connected succussfully after few attempts. But, after that I am unable to connect to UMTS mode, when I manually configure the GSM/UMTS mode. Once the UMTS is chosen, not just 3g but the mobile network too gets disconnected (Cross checked the 3g connectivity with other mobile and also the same sim works in other mobile). The mobile supports 3 modes, Global, CDMA & GSM/UMTS. Out of these only GSM is working now. Earlier Global mode too worked (not sure about CDMA mode). At the same time, when I connect the device with the car, UMTS starts working. Once disconnected, the behaviour is unpredictable. Sometimes it works with UMTS for couple of hours and in some other times need to switch to GSM to get the mobile network.
I tried to do factory reset, relock, etc, except flashing the ROM (which didnt start at all when tried). Tried restoring the stock recovery as well to install the latest updates from HTC. But, its not installing. Any idea to resolve the issue, apart from flashing the ROM? Does android support stand alone driver installation or any other solution?
Note: Hope you wont suggest to throw the mobile and get a new one
