NOTE: I always bye At&t phones and i have no problems att all in my country since its the same frequency,,, \

Perhaps you need to check your APN settings ??
And verify you have the correct modem for your region....g

Thanks for your response, but i don't have signal at all, but the phone automatically detects my apn settings, and can read the sim card, but there is no signal, it might be the modem, but i tried tmobile modem and att modem neither one was working.

3G problem on F180L

Hello guys,
i ve changed today provider and 3G is not working.When i open data,it is always under GPRS.Can anyone think hw can i solve this?Also the provider is vodafone.If i download the Greek KDZ (wich is for the phone been sold by vodafone) will change something?is there any posibility to work without changing baseband?cause i think that if i change rom and then baseband same error will occur.

may be the access point is wrong,may be you can press "*#*#4636#*#*"to select a proper network mode,and i believe if you flash kdz will give you 3g back,but it is the last way.

May be incompatible frequencies?
F180L is version for LG Telecom which doesnt use WCDMA network.
F180L does supports WCDMA, but as i remember it has some odd frequencies.
And check the APN

well with my former provider it worked fine.And its strange cause sometimes 3g works with this provider too!the bad thing is that i cant choose in this rom in what mode i want to connect.In open european mode it had some options,also in stock avatar rom.I think ill try a hard reset and if i dont have any changes ill try to use open european version.Btw does anybody know,if i change to european version,can i have OTA updates?Or ill have to dowload it everytime and install it through KDZ updater?
Btw its F180l U+ edition from Korea

I tried this but when I clicked on the "select radio band" option, it gave me an error notice "?unfortunately, the process com.android.phone has stopped". Plz how do I rectify? NB... My device has no connection to any of the carrier networks after upgrade.

Are you able to use 2G atleast? Did you check the APN settings for your carrier?

Yes, I can use 2G. I checked apn settings. When I select WCDMA only, network just goes off. but when GSM or WCDMA Preffered is selected, then only 2G starts.

[Q] No LTE!

Hi All,
I am a G3 User from Singapore and my model is the D855. I've noticed that after rooting and changing to Custom ROMs I've only been able to get H+ and never LTE. Before when I just got my phone it was able to receive LTE.
What is the problem here? Do I have to flash some modem update or something? I'm not clear in this area so any help is appreciated!
I'm very sorry if I'm not doing something or doing something really stupid.
Thanks guys!
EDIT: By the way, I've selected LTE under "Preferred Network Type" and I still get H+.

Check the APN settings and make sure they're correct for your carrier. Custom ROMs don't always have the APN settings configured correctly.

My LG G3 only connects to Edge network

Hello guys.
After a couple of days reading on the internet without success I decided to share my problem here.
I bought a LG g3 D850 32 gb on eBay, once I received it I was so happy enjoying the 4g LTE network, the speed was amazing.
Regrettably, one day all this happiness disappeared, now I only have Edge connection, I don't have 3g, hsdpa or 4g, I only get the awful Edge.
I have tried using my sim card on other phone and I get 3g and hsdpa (that phone does not have 4g) so the problem is on the G3.
I have to say that I have the phone with the stock rom and the only change I've done was to root it with kingroot and deleted (disable) some at&t apps. I thought this was the problem so I restored to factory defaults but the problem did not disappear.
I was thinking in to return the phone but I am in Chile so is a little hard.
I will be grateful if some one could help me with this issue.
I will be waiting for your comments
Thanks on advance

What model number/version/baseband/etc.
What's your base network and are you sure your APN settings are correct?

Hi Nick,
This is the Software info:
Android Version: 5.0.1
Baseband Version: MPSS.DI.2.0.1.c1.13-00058-M8974AAAAANPZM-1
Kernel Version: 3.4.0
Build Number: LRX21Y
Software Version: D85021r
Security Software Version: MDF v1.1 Release 3
I do not understand what the base network is. Is my cellullar provider?
The APN settings are OK. I didn't change anything.
I had all the connections and suddenly I lost 3 and 4 g and only get Edge.
I didn't change anything. I rooted the phone with KingRoot but I am not sure if the problem started in that moment.
I have made the Factory Data Reset a couple of times and the problem continues.
My Sim Card works fine in other cell phone.
Please Help!!!!

I had the same problem when I switched the operator. Went there and the man there tried everything but nothing helped. Last thing he suggested was to do a software update, did it an 4G speed came back

Yes, your cellular provider. What's your cellular provider and what's your APN? Is your sim from AT&T, a foreign provider or from a Chilean network? Does the APN match the SIM provider's APN?
I'm thinking that it's either an APN problem or a band switching problem (since you disabled some AT&T apps) or you just ran through your allotment of 4G data under your contract.
If you've tried your SIM very recently in a friend's phone and it works just fine, then it's probably not a data allotment problem.

I am using a chilean provider with the correct APN, the same I used from the first day when 4g were working fine and the same.
Yesterday I tried mi sim card in other cellphone and I got 4g without problem. I checked the apn and they was the same.
Now I tried with tho different ROMs, I changed the kernel and the modem and I'm still get only EDGE :crying::crying:
I do not know what to do. I think the cellphone is bad

I'm guessing that you may have disabled something when you were deleting the AT&T bloatware. You've got a D850, right?
As @trickie69r has mentioned in a previous thread, try downloading your KDZ direcly from LG's Servers using: http://csmg.lgmobile.com:9002/csmg/b...XXXXXXXXXXXXXX
(Replace XXXXXXXXXXXXXXXXX with your own IMEI, which can be found by dialing *#06* in Dialer)
Take a screenshot of your About Phone > Software Info tab before and after and see if anything changes.
Buena suerte!

Thank you Nick.
I have flashed some Roms, and the problem did not solve.
I have tried to download the stock rom but I can't download it from the link you send me. I can't find D850 stock rom.
Do you have other link to get it?

Did you try using the ROM in this thread, or just installing the AT&T apps to see if those worked?

Yes I tried that rom and stock kit kat and nothing works.
I think the cell phone is defective because I have other LG g3 and works fine
