3G/4G Doesn't work - G2 Q&A, Help & Troubleshooting

I have an LG G2 D800 with the Cloudy G2 3.3 ROM.
I live in argentina and I use CLARO as my service provider, like all my family.
My father has an Moto G 4G, my mother an Moto E and my little brother a Nexus 4, none of them has any connectivity problems except of me.
The ROM is not the problem because I have already tried the stock one and I don't get connection either.
The APN is set correctly, anyone has an idea about what to do? I really need internet when I'm not at home.
Any help appreciated.

Try flashing another modem. Make sure the modem is meant the android version you are currently on.

I'm on LP, and flashed the only modem for LP, downloaded from blastgator's page.
I don't know what else to try. The thing is that it has worked, It's not a network compatibility problem..

Rooting and unlocking are two different things.
Rooting = full access to the android system.
Unlocking = network unlocking, so you can use the Robbers S4 on AT&T or another network.

Hey guys,
I used the above guys and managed to install CM 10.2 and it works.. okay.. I have to admit that I want to go back and try a debloated TW Rom again so that I can use the multiwindow, roaming and camera support that comes with the phone.
The biggest issue I have noticed that a number of ROMS do NOT show up in my Goo-Manager. I am guessing it is because of my MDJ Base-band. I have done some searching but cannot find any note of changing from MDJ - to MDL and therefore opening up some ROMS like CleanROM.
Please let me know if you have done anything like this before.
Cheers
Travis

[Q] Flashed LG LS970 & LS980 3G Connection Problem

Hello. I flashed a Sprint LG G2 to PagePlus. The Flash goes well and All my items stick. But the problem is the connection is unstable. I'm noticed with both the LS970 and LS980 the same problem happens. The mobile data will first connect with 1x then to Evdo. Then the network will disconnect. I flash phones to pageplus all the time and they all have 3G - EVDO. But the unstable 3G is crazy. It will not stay connected. Why are the new LG phones like this? Has anyone encountered this problem and found a solution? I look forward to people's reply because I know a lot of people have run into this problem. Thanks in advanced.

Hello. Absolutely! That's my personal phone! Just make sure when you flash it, you leave the SIM card in the phone. 3g data works, mms, etc. Good luck.

The flashing method is same for all phones. Doesn't matter what kind. I'll give you a good starting place. Viper32 has a forum on here helping people with flashing. And there are plenty of forums with a ton of info. Good luck.

What happened with mines is similar but I had the att variant
So I flashed mime to sprint and it worked but only on their 1x network and 3g towers in order for 4g to work and there new spark network I had to get a Sim card and pop it in and boom 4g LTE worked the sec I put it in

Any issues with losing call history at all, after flashing it to PagePlus?

No. Call history has nothing to do with flashing. The only way you can lose call history is if you factory reset the phone or you personally delete the call history yourself.

Actually its a known issue with this phone, that it looses its call history when flashed.
It has something to do with the Stock ROM release
I have the same issue.
Also I get a "MIP : 89" error sometimes.
Also, I have a system update downloaded waiting to install but not sure if it'll kill my flash so I've been scared to hit the button.

Is your phone the LS980? I had a customer who updated his LS980 this past week and I had to re-flash his phone. You'll probably have to re-flash as well.

Have a D802 on three uk. Like others went down the route of rooting and flashing cm 11 on my device. All quite straight forward, never had a problem... decide to purchase an s5 so now need to sell my lg. Originally flashed a stock Rom through TWRP and now unable to receive data. Though it was a problem with the rom so I flashed LG firmware through update tool. And have three UK firmware on but same problem!! All toggles selected..data,3G, airplane mode on off, reboot. ..nothing. my 3 UK sim works fine on my s5 so not that. I can get signal fine but no data. Would really appreciate some help as I cannot understand what's the problem. Especially as I can get signal but no data and works fine in my s5 ?

I suspect you didn't do a FULL wipe before flashing....
Suggest you try that first as the APNs for 3UK may be corrupt.
You could try manually setting the APNs but honestly, the Factory Reset option and reflash is easier and fully effective.
The one thing I didn't try. Worked. Thanks very much.....wanna by an lg g2 haha. Cheers bud

By the way, could you give me a link to the tool that lets you go back to stock? I was thinking of rooting and doing various things, but I want to make sure I know how to go back to stock so that I can take future OTA's.
I got all my info here bud. First page.

[Q] Can you make Verizon LG G2 work on MetroPCS?

I have an LG G2 and want to give it as a present to someone on MetroPCS. Is it possible to flash it or configure it to work on MetroPCS network?
I couldn't find an answer anywhere on google so I came here.
Thank you so much!
Please help..

Im about to do the same thing, ill let you know how it goes..
MetroPCS is under T-Mobile's network so it should work. I'm using a verizon Lg G2 on T-Mobile and it works fine. You just have to root it and load a custom rom like CM or anything like it. The stock rom of the verizon G2 won't recognize a T-Mobile sim card so that's why you have to load a custom rom.
Just wondering if you were able to make it work? because I got a Verizon G2 with Cloudy G3 ROM and it wont work on Metro.
Try choosing the T-Mobile variant. That's what I did to get simple mobile Sim card to work, but do not do it if your scared it's going brick your phone. I don't have the vs980 I have the ls980 and it worked.

G2 won't connect to LTE

Hi all there
I brought a couple of LG G2 D800 (AT&T Version) from the US to Argentina. After upgrading to Lollipop both were able to connect to LTE using different local providers. LTE uses BAND 4 here. This worked well for 3 months aprox. Suddenly (after a short trip to another country) one of the devices stopped connecting to LTE. Something seems to have changed on the device. I don't believe the issue is the SIM/provider. It seems BAND 4 is not working anymore on that device (at least now the local provider app says the phone is not "ready for 4G" and I don't know how to set this up. Through the hidden menu I get to the LTE section and, regardless of the LTE BAND I select, it always returns a "FAIL" Message. I tried a factory reset already. I'm running stock 5.0.2. I don't know what else to try.
Thanks in advance!
Flash different modems for your phone. Start by flashing a lollipop modem and see if anything changes

Try this to change to LTE.
If problem still not solving then flash another modem.

1st: Thanks for helping!
I tried but a message pops up ""This application does not work on this device".
Any pointers on where to find and how to install the proper modem for my D800 stock Android 5.0.2?
Search Google and XDA

took me longer than planned. After rooting, installing TWRP and trying the 5 different modems I found for D800 (http://www.gregtwallace.com/lgg2-projects/modem/) none of them seem to make any different. What else rather than the modem could I try? Does it make sense to flash a different variant modem such as D801 (T-Mobile) that also has band 4?
Thanks!
