I have an LG Optimus L5 sim unlocked and now 3G doesn't work anymore, 2G works fine, on either stock or custom ROM, but 3G doesn't on both stock and custom ROM, yes I am in a 3G coverage area since other phones can capt 3G signal just fine, but the second I turn on 3G it loses network immediately and doesn't let me access the internet or do anything that requires the SIM network.
However in Cyanogenmod 3G works sometimes, sometimes it connects just fine (with super low signal) and sometimes it just disconnects altogether like its doing right now on stock ROM
What should I do? I already reflashed the V20 baseband (I'm on Stock 4.1.2) and that didn't fixed anything

Hi,
I am on stock pre-rooted Djemby's XXUBMGA for I9505. I am in a very good 3g reception zone. My S2 picks up 3g easily, but my S4 doesn't.
I have tried ktoonsez kernel as well. have reinstalled rom couple of times with full wipe but no luck.
I have the mobile data option on and it'son WCDMA/GSM (auto) mode.
Everything works fine except for the 3g. I get it sometimes but most of the times its dead. I don't see any H/H+ symbol.
I do have access points setup. I even have tried reset APN to default. Sometimes it works. But mot of the times it doesn't.
I want to be able to get uninterrupted 3g (H/H+) data when I am in 3g zone.
Please help

Hi,
It may be that a new modem might get a better signal for you.
Ask in THIS THREAD
Someone might suggest a better one for your area.
Hi Everyone,
I have flashed the ZVA update, with the OPTIMUS rom. Everything seemed OK but there's something I noticed, I barely get LTE now and whenever I am running 3G I lose GPS signal. It's visa versa too. If I get GPS signal, I lose 3G/Data capability. Does anyone have any advice?

I recently upgraded to Baja ROM from rooted JB stock and ever since have had problems switching to 3G from 4G. If I turn my phone on in a 3G area, 3G data works. However, if I travel to a 4G area and the phone connects to 4G, when I return to a 3G area, 3G data no longer works. The notification bar has a grey out 3G (wifi is off). Voice still works. I cannot get data again unless I either go back to a 4G area or reboot my phone. Turning on and off airplane mode doesn't help. Does anyone else have this problem? I have tried various modems, including NC4, NC2 and MJE. They don't seem to make any difference. Anybody have any suggestions? Thanks for you help in advance.
P.S. I live in Appalachian mountains where I am constantly roaming on Appalachian Wireless. They did partner up with Verizon to get 4G LTE so I suspect when I am on 4G, I am on Verizon network. I don't know if roaming makes any difference.
Hi everyone !
Lately I went to a place were 3G/4G was not reachable and it is there that i noticed that my brand new Moto X play couldn't get any connection in 2G (GSM) mode even if the place was fully covered with 2G/EDGE (GSM)...
In 3G/4G there is no problem only on 2G (GSM).
I tried in the settings to put 2G (GSM) only and I can not get any signal even now that i'm back home ....
I tried a factory reset from the recovery it did not work :crying: Do you have an idea on how to solve that problem ?
I also tried to use the sim card with another phone in 2G (GSM) and there it works fine with maximal signal ....
Thanks ! :laugh:
Hallo,
I did a test and I got the same "problem".
Turned 4G into 3G...no problem.Still connected..
Turned 3G into 2G....no signal.
Turned 4G into 2G..no signal.
You can try to switch networktype in *#*#4636#*#*
No time for me now....I will try it later on the day.

I just tried it and turned the networktype to "GSM only" then i got no signal just like before. If i try to use another type like CDMA/GSM it connects to 3G and works but still the problem with the GSM/2G....
Hi guys. I'm not experiencing this problem on my XT1562. switching between bands is fine and working on my device. What kernels are you guys using?
I'm using the stock kernel, I just flashed the OTA (6.0.1) from the stock recovery
Same Problem, more information
For my Moto Play X I have a very similar problem:
4G works, but 3G and 2G do not. If I'm connected to a 4G network, I see that there is reception and can use all data transfer functions. But when I want to do a call, I get a timeout. When I'm in a place where there is no 4G network available, I see that I don't have signal - but the network is shown in the list of available networks for manual selection.
As I have a dual SIM variant (stock ROM, not a custom modification or "upgrade") my second SIM does work like a charm. I tried now and swapped the SIMs - and it seems that just the SIM1 slot is having those problems. The same SIM also works perfectly in the second SIM slot.
I also tries to reset just the network settings (an option provided by the stock ROM) but this didn't change anything.
Next step I'm currently working on is doing a factory reset - will take a while until backup and restore will enable me to see the real result. I'll keep you up to date....
UPDATE: factory reset didn't change anything - will send phone to repair now. :,-(
Hi guys,
Recently bought a used(6 months) OnePlus 2 - 2003...I was really satisfied with the performance and huge 4gig ram. I use only a single sim, which has 4G. I used the sim with a Nexus 5 until the phone die, but I have never had any signal issue with that phone. In y country not every area has 4G coverage. I currently have Oreo resurrection remix rom, latest build. In my home town 3G, 4G coverage is at it's best and even on 3G coverage I got decent amount of speed with Nexus 5.
The problem is OnePlus 2 doesn't give the slightest speed that H+ is capable even while I'm on 4G. speed is about 500kbps max with 4G. If I chose WCDMA Preferred, from the service menu, it does show H+, but I can't surf on the internet. I'm very disappointed with this phone now. If I were to go to an area with no 4G, It won't get data connection turned on no matter what I do. I even flashed latest OOS 3.6.1 firmware but no luck. I went back to OOS 3.6.1 and it's the same, cant' switch to 3G data.
Man I don't know what to do now, I don't get wifi all the time when I'm away from home. Is there any way to disable 4G and just use H+ or 3G?
I even changed the band in service menu (*#*#4636*#*#)
Also flashed the latest lineage 15.1, CM 13 and no matter what I do
I also tried couple of other sim/ISPs but no luck
Please Help me
Use Network Signal Guru app(root needed). In app, select LTE band lock and deselect your LTE bands(depend on your carrier) use for 4g and exit. It will prevent your phone from connecting to LTE band. Enable the band again to get the LTE.
