No 3g connectivity d850 - AT&T LG G3

I had a weird problem with my d850 as stated and solved in the following thread http://forum.xda-developers.com/att-lg-g3/help/gsm-edge-connectivity-t3179084
Although i am back to netowrk but only gsm is working with edge. I am unable to connect to 3g even though i have auto detection on preferred network. Prior to the repair as mentioned in thr linked thread the phone worked fine on 2g 3g and 4g.
Any guesses ? Should i try reflashing baseband ? Or any other way i can test my hardware or anything that may help.

Hero h2000+ 3g help

I have a Hero h2000+ and have t-mobile (CROATIA) for my network and for some reason it's always stuck on EDGE mode on their network. I know this phone supports up to 3G but can never seem to get that corrected. I even manually setup the APN and still nothing. Would like any advice on how to resolve this issue. Thanks.
P.S.
Yes I did put the SIM onto the WCDMA slot.
no idea?

[Q] LTE radio works but no internet connection - CM 10.1/10.2/11 on XT925

I've seen some similar questions here but none of them could fit my issue. I can't connect on LTE network on any version of CM/PA/etc. I still can send texts and do calls on LTE baseband, but internet only works when I toggle my phone to GSM/CDMA instead of LTE. It worked on the stock ROM and I'm in a place with a good LTE signal, I think there's something with the baseband frequency, probably Brazil's frequency is not available on those ROMs. Can someone help me?
Thanks.
UPDATE: Finally I could fix it. The APN was not properly configured.

I'm from Brazil too, but i'm having other problem, with the WiFi, every Custom ROM I flash the WiFi becomes really weak, and when I go back to Stock everything is normal, don't know what to do :/

I'm having exactly the same issue and also tought it might be related to the baseband frequency (2.6GHz).
Which carrier are you on and which APN configuration change have you made?
Thanks in advance!
UPDATE: TIM Brazil's users: Changed APN to timbrasil.br, Authentication Type to None and Bearer to LTE and worked like a charm.

Problem with 3G

Hello! My OPO had issues with OTA updates (25R specifically) and 3G. I clean installed 38R with no issues, everything went well however the 3G is down or works for a brief moment and then loses connectivity. Neither 2G nor 3G works. I live in Greece (if it helps more about understanding the network problem).
Any help appreciated!

I see that you are from Manila and using a F350L please check supported bands by your network and the supported bands of F350L if they are compatible.
i did check it and it is same bands use here. there are f350L users here with no problems using their 3G connection.
My F350L is LTE-8 other F350L are LTE-A. I suspect that this two have different band
I am having the same Problem up here in Ohio
No matter what I try I can not seem to get this phone to do anything besides just G I am running the F350S on AT&T
Please look in Dialer with 5457#*350# and activate your Bands
Still no dice

Hi folks, I am Nigerian and I use an LG G Pro (D838). Some days back i noticed that i had no network on my phone so I tried inserting another sim into the device and still got the same result but other devices around had network coverage. I changed the network mode to GSM only and got 2G but WCDMA only gives me nothing. I have tried other sims on GSM only mode and got 2G but when i change the mode to WCDMA only, i get nothing at all. Have also put it to GSM/WCDMA auto but keeps giving me just 2G network only. I have even had to downgrade the OS from android 5.0.1 to 4.4.2 as suggested by a friend and still got the same issue. Please, what should i do??????
Same problem overhere Lg g pro 2 though F350k
I have the same problem in Holland. I have the F350k variant) 3G is in Holland 900/2100. The phone has despite of the advertisement text !!! by selling (900/2100) 850/1900/2100. The 2100 band is the same so should work.
Tried a lot. By the way last software and Androi 5.0.1.
The Sim is not the problem, the APN setting not, ........
any suggestions?
Could it be somewhere oleh software??????

Hello, I am from Nigeria.
I bought my LG D838 on eBay in May 2015 and was quite impressed with the performance but my pride and happiness was short lived. I woke up one morning in December 2015, and noticed I didn't have any cell reception. I checked with my siblings and I seemed to be the only one who had no cell reception on the same network as theirs.
I swapped SIMS of other networks into my phone but still to no avail but funny thing was that whenever I change network mode to 2G only, I get reception but switching back to 3G only mode gave me nothing at all...this happened a few days after I updated the OS with a 50MB patch file using OTA as prompted. I have been writing to LG since then but no reply and it has frustrated me so much as I bought this phone for about USD 398 and didn't even get to use it up to a year. I managed it on 2G while trying to contact LG about it until the Wi-Fi and Bluetooth stopped responding also. I need the NV and QCN backup file for this phone in order to get it running again…I would really love to see this beauty run again. Please help me out.
You can contact me or send the file to [email protected]. I am open to suggestions.
Thanks in anticipation.
