4G LTE lost after using Wifi - LG G Flex 2

Hello,
I bought the H950 AT&T unlocked and currently using it with a T-Mobile SIM card. I was able to get 4G data after setting the APN, but I ran into a strange issue: Everytime I enable Wifi, I couldn't get 4G again, even if I turn on/off mobile data (already disabled Wifi).
For now the only thing to make it work again is to restart the phone.
Does anyone have the same problem and how did you fix it?
Thanks in advance.

I dont have that problem with pr rom and h955 v15e system

I have the same issue. Hopefully upgrade to Marshmallow will fix. In the interim I have been using Network Signal refresher lite by 8JAPPS. Has worked every time. Wish I could automate it though.
Sorry I can't post the link yet.

Thank you. I have never root any devices so I'm a bit afraid to do it on H950. Perhaps I will wait until the Marshmallow ROM and try it.

[SOLVED] 3g not working in India

Well, i haven't used 3g till now, and today activated it, only to find that it doesnt work.
DDKP3
BCK Kernel Beta 13
Deodexed
No other mods.
Network mode is automatic
When i select WCDMA only. The phone is not able to connect to the network.
And on automatic, the phone stays on EDGE only
Anyone insights on it?
Had read Argentine people having 3g problems long ago. Anyone from there can help?
Also had read somewhere that it might be a CSC problem. I checked using *#1234# to see if CSC is unknown, but its proper.
More info from further posts and replies -
Service provider is Vodafone India.
Confirmed that its a phone problem, by using the SIM in another phone [SE Xperia Arc], and it worked on it.
SOLUTION -
Well, I had removed the sim to try it on another phone, and well on putting it back in the phone, it worked!
I actually feel like a noob after this!
Anyway, thanks everyone for trying to help!
I'm using 3g.... its working great!!! What service do you use? Also are u sure you have subscribed to 3G services... sometimes it takes a while to get activated.

3g works for me and have been using it for over a year now.
Vodafone and ICS 4.0.4

Yea, obviously it isn't a general problem faced by all.
I guess, someone who's faced such a problem only might be able to help.
Had read alot of people having such issues, but now searching isn't giving quite the required results.
If you can, try your SIM card into another smartphone which is confirmed working with 3G, just to be sure the problem comes from your phone.

I had a similar problem, never got any help that worked, ended up sending it in and got a replacement. Here is my thread, not sure it will help any. http://forum.xda-developers.com/showthread.php?t=2763671
Did you find a solution? I'm having the exact same problem (I live in Denmark). Modified some radio-settings with the Thunderbolt app and ended up with no signal. Don't know what to do!
Hi solved like that:
I have installed a custom rom. Than when finished I went in setting and I have selected gsm only. Than I have rebooted and installed an app called phone testing . Inside I went in phone setting and in the menu I have selected band and then automatic. Rebooted and it works.
Let me know

Thank you very much for your answer! However I'm still having the same issue. Installed a custom rom (ViperOne). Tried to select GSM Only in settings but it will not let me do that. It stays in Global mode for some reason.
I'm not sure if I found the right app (Phone Testing) but it looks a lot like the 'Thunderbolt' app that caused the signal issue (actually the apps are identical). In the phone testing app I tapped "Select band" and got those two options: "USA Band" and "Cellular (800-MHz Band)". Don't see any "Automatic"-options.
Yesterday when trying to improve my signal I tapped "Cellular (800-MHz Band)" in the "Thunderbolt" app and since then I haven't been able to get any signal.
Do you have any other suggestions?

Ok, I'll try that. But where did you download it? As far as I can see it's not compatible with the Verizon One M8.

I was wondering if you have LTE in France? Everything works perfect for me now except LTE. The Verizon ONE M8 should support all the LTE bands we use in Europe so I don't know why it doesn't work for me.

It appears to be a baseband-related problem as a lot of VZW M8 users have problems with LTE in the US also (with T-Mobile for example).
Unfortunately there is no much options for our devices as the only compatible radio is the Verizon "0.89.20.0321", (don't flash any GSM device radio as your could end with NO IMEI and NO BASEBAND because the partitions diference),
Because of that we don't have any other option than wait for HTC to roll out an update for Verizon's M8 radio. (I hope they release it soon).

I did the same thing as you, but at that time i used ARHD 11.1 - it was the latest available. I'm not sure about 20.3. I'm on Viper 2.5.0 now. I think you can use 11.2 that is available - it's 4.4.3 based, we don't have 4.4.4 base for verizon yet. Or you can PM me for a way to send you my copy of 11.1.

Sorry to bring you bad news but what you trying to do isn't possible,

I'm on the same boat and am really upset that Samsung makes things harder
every year and this time around CSC is totally different now.
Please let me know if you find any good news.
Switch to the canadian model and you'll have everything but root, i'm sure theres plenty of people that will do a straight swap.

download the rogers firmware from sammobile and join batstock rom telegram support channel. The OP can help you out. All you have to do is upload a file from the download there and he'll add the csc to a flashable twrp zip that you can install to fully enable all rogers features.

I got bad news for you. VOLTE and Wifi calling only works on android phones that has been bought from Rogers. I have the unlocked version from Samsung.ca and it still didn't work.
Correction: The only unlocked phones that work on Rogers VOLTE and Wifi-Calling are the iPhones.

i see.
next thing you want to try, make sure your build.prop product name matches that of the rogers phone.
also, my carrier disables feature if it detects root such as wifi calling. if you have magisk hide and an app for wifi calling uou may want to try hiding those apps from root.

I already called Rogers tech and VOLTE and WIFI Calling don't work on Android phones that was not from Rogers. No matter what you do, its the IMEI number that triggers their system to enable it on their end.
Unfortunately all carriers including Bell, Telus, Fido, Virgin and Freedom Mobile do this.
if it trully is incompatible, it is more likely to do with the difference between th band availability between the international model and canadian model... a quick google search will allow you to compare band availvility between phones and what bands are used for the carrier.
i don't believe it though, that just makes it hardee for them to aquire clients with existing handsets.

Help is this problem software or hardware ??

I would like to know if anyone else has this problem in their note 8
My note 8 drop calls,2g,3g,4g randomly but almost 100% when im calling someone or if someone else is calling me i cant pick up becouse it says network not available some times it goes 9 times in a row with this if im trying to have a call but sometimes its ok
Wifi is 100% stable no problems there
I tried all available roms out there for my sm-n950f but same problem even in stock rom
This problem started about 2 months ago
Now currently im in stock pie
I hope someone know how to fix this
My phone is not doing what is supossed to do calls lol
