LG P930 can't connect to cellular UTMS network

Hi everyone,
So I installed CM10 on my P930. Since then, I couldn't connect to my carrier's cellular network. I can't make calls, receive text messages, or access mobile data. Can anyone give me some advice in terms of what to do?
Thanks.

Hi Rani,
No luck. I flashed every single baseband there was in this thread by drumist (http://forum.xda-developers.com/showthread.php?t=1842763), but none worked.

well try unbrick and don't flash official ics

I tried the unbrick, no luck either.
I just noticed that the lock screen says no SIM card, when I actually do have a SIM card installed.

Are you on at&t? I think those basebands are at&t only. If you are bad sim?

No, the original carrier is Bell. I unlocked it and I'm using it on Rogers now. I tried another Rogers SIM, but still don't work.

You probably need to put in your APN settings.

does anyone have the Bell stock gingerbread ROM i could restore? Want to send it to LG for warranty repair. I looked at the SIM slot and it looks like its missing a gold contact (top right).

[Q] Australian Vodafone GN2 LTE settings disabled

Hi everyone I have a 2 week old SGN2 N7105T from Vodafone Australia.
As Voda in Australia doesn't have 4g yet it seems Voda/Samsung has disabled 4g LTE on the phone.
Which means I cannot use another sim from another carrier to reap the benefits of 4g.
In the settings I only have options for wcdm/gsm auto, wcdma only & gsm only.
Does anyone know if and how I can enable 4g?
I have thought about rooting and putting a different rom from a different country or one from another carrier in Oz (such as Optus 1800mhz) that has the 4g option.
Not sure if that will allow me to get 4g? (By using an Optus sim)
Thanks

Vodafone Australia doesn't have 4g network just yet. They are planning to upgrade by June/ july 2013. Thats why they disabled lte option on note 2 7105t for now. even if you are able to get lte option by flashing different rom you won't be able to get 4g network.
This is seriously against the consumer right as we pay premium price for 7105 only for lte reason. But we get the phone same as 7100

Your current provider has no bearings on the menu options, so the option will not change.

I think this is not correct. 4g connection is not disabled on the phone. Because the carrier does not support 4g at the moment, the LTE option in the menu will not be visible. That is the impression that I have got from a Vodafone NZ engineer.

Sorry for the late reply guys.
I installed a German Vodafone 4.1.2 rom from samfirmware which gave me the option to choose LTE, GSM, WCDMA then I put my mates Telstra 4g sim and 4g worked great. When. I was in 4g areas the 4g symbol showed on top and speeds were awesome. Now all we need is Vodafone to hurry up.

Sorry man you're flat wrong.
I flashed a rom I found on here for the N7100 that was confirmed compatible with my N7105-t From Voda and put in my telstra sim and 4G'ed my brains out.
It was getting crazy numbers for up and down speed in speed test so I know it was legit. That and the 4G logo up the top....

You used telstra sim and got 4g, because telstea have 4g networks. Nothing wrong with that. So how I am wrong here? I said getting 4g compatible rom doesn't mean you get 4g from VODAFONE because they don't have 4g. tell me if I am still wrong. Thankx

Settings->More->About Phone. You'd be looking for baseband on that screen; it should be M919UVUAMDL. If it's **MDB you could try updating your modem/baseband.

[Q] Enable LTE access on T-Mobile's network

I have an AT&T SGH-I747 running CM11 that I have unlocked and using on T-mobile's network. Unfortunately though I can only access edge and I would like to be able to acces 3g, 4g, or LTE. How would I go about enabling this on my phone? Any help is appreciated.

I used to work for t-mobile and that's the LTE APN...
check on their website the LTE coverage areas around you.
Make a backup of your device and attempt a factory reset.
there were some devices I worked with that the factory reset worked like a magic trick.

I can't really do a factory reset, as I am currently running CM11 and I was previously on ATT. My friend on Tmobile get's LTE coverage here so I would assume I would be capable of that as well. Or at least get 3g coverage.

Cannot lock on to a 4G signal on my SM-N900T

Hi
So I have a T-mobile unlocked SM-N900T that I'm currently using in London. I'm on Lycamobile and want to try their 4G network but for some reason my phone just will not connect to LTE. 3G works fine but that's as far as it will go.
I've been able to use 4G in India on the same phone so I know it does work, but for some reason it just wont connect here. I've tried the *#2263# service menu and selecting LTE -> ALL just gives me the no signal / network icon.
Have tried resetting, pulling out the battery and SIM but nothing seems to work.
Has anyone had these issues or any suggestions?
Oh - phone is Unrooted and running the latest KK update.
Any help or advice is graciously accepted. Cheers!

They just might be using a band for LTE that the phone doesn't have/support.

It handles a bunch of them, but not all. I'd look up the band their service uses for 4G, and see if it's compatible with your phone.

Cheers sir. I'm on the phone with them now and they don't seem to know! What are the usual bands that would normally be used in London though?

Thanks Andrew. I'll give that a go. They've called me a few times but keep reading from the same script. Was promised a call back on Sunday, but nothing and its Tuesday already!
They don't offer contracts as they are only PAYG but let me look up specs for O2, as they piggyback their network.
Sent from my SM-N900T using xda app-developers app

Ok. ..so it would seem that the tmobile phones operate on different lte bands. So I've attempted to flash an international rom on this phone and as the Eagle eyed will note, this was done successfully. I should therefore have an international modem etc now? But I still can't connect to 4G! So does this mean that this is a device (actual hardware) issue or can this be sorted by flashing a modem that allows me to connect to all bands?
