My phone is a Nexus One w/ CM7 installed with the latest radio and I live in the US. I read to go into the Phone Info settings and switch the 'Preferred Network Type' field to WCDMA Only to force the phone into 3g mode but when I do this I get the message 'fail because Radio not available' under GSM disconnects DATA. I tried flashing several different radios and this did not help.
I get a connection when using WCDMA Preferred but I am restricted to the E or the G symbol in my notification bar. I want the 3G symbol!
I am out of ideas here!
i got exactly the same problem ... !
might help...
have you tried toggling airplane mode off... then on... then toggle data off... then on?... it might work... then again, it may not... dosent hurt to try i guess...

So I stumbled upon something interesting the other day while running a CSDI ROM. I noticed I was unable to use 3G data anymore even if I had full reception and my menu bar indicated a 3G signal was present. Funny thing is I can connect and use 2G just fine.
Since then I've tried wiping, flashing other roms, upgrading recovery, reformatting and partitioning my SD card but to no avail. I don't believe it to be a problem with T-Mobile's 3G network either (I've since called them an am awaiting any further help they could be).
I've made sure "T-Mobile" was selected under "Network operators" but that didn't seem to help. I know I can "use only 2G networks" but that would just be silly to not try and get my 3G up and running again.
Is anyone able to shed some light or have any input into this situation?
Current ROM: superD 1.11
HBOOT-1.33.0006
RADIO-2.22.23.02
8 GB Class 6 SD card
Thanks,

Try *#*#4636#*#* ,and then you can see information phone,there select "wcdma only".I have the same problem like you,the reason is that signal 3G no strenth enourgh and phone always change net between 2G and 3G.

Thanks for your help, however after switching that setting, it worked for a little bit, then the data connection stopped functioning again. Even though it shows "3G" at the top with 3-4 bars, I simply keep losing the data connection whenever I access the internet.
This is very annoying...
Hi there!
I've some problems with my G-Nexus 5, as wroten in title,
the Wi-Fi and the 3g connection disconnects me during utilizing it,
if i look on the icons of wi-fi or 3g i can see that i'm not receiving any data and i cant continue to surf in web or by enjoying a game online.
So the question is its a hardware or a software problem, and if another one had the same problem.
So noone had this issue?
Sounds like hardware if this happens both to 3G and WIFI.
How do you fix it? Toggle Wifi? Airplane mode? Restart phone?
After a bit it begins to surf something like 5-10 seconds
I get the same problem on my 3G, it doesn't happen while I'm on WiFi. I have to disable/enable data or airplane mode on/off to get this working again. Also I have noticed that when signal changes from 3G to EDGE and then back to 3G I don't have data working. Need to to the same trick to have that back. It's annoying and you don't know when it working or not unless you check your phone....and lose notification from Facebook Messenger or Whatsapp which i use a lot.
I wrote to google lets see what do they say....
I got realy bored about thia issue.
I would verify that your apn settings are correct. Either call your carrier or maybe google your ("carrier name" apn settings). Also... Settings/Wireless & networks/More/Mobile networks/Preferred network type, is correct. I do know that in my case as far as wifi I get better results (quicker to connect) if the "Advanced " settings for "WiFi frequency band" is set to 2.4 GHz only. Default is Auto. Worth a shot.

Tried does'nt work, i loos the connection anyway
some time ago i set the phone to LTE in the testing menu to see what LTE networks it could see. it saw them fine but not for the network i use yet.
the thing is ever since then everytime the phone reboots it seems to default back to LTE only. soi have to ga back in to the test menue and set it back to LTE/ GSM to get the signal back.
Help! why is it still doing this and how can i fix it?
Go to Settings, More... under Data usage, Mobile networks, Preferred network type. Make sure the radio button for 3G is selected.
so i cant leave it on 4g preferred? 4g should be coming to my location in the next coulpe weeks so id not want that to be perminant.
or will setting it to 3g reset things?
ooooooh, did as you said rebooted, 3g locked on. sat back to 4g preferred and rebooted, 3g locked on.
yey! thanks, i dont get why it worked but much appreciated.
Hi guys,
I normally am not a big responder or thread creator here.. Just a happy Photon Q user … but now I am looking for your help!
I own a Photon Q modded by CornholioGSM. Worked like a charm untill I got on a plane last week. (From Netherlands to Italy)..
When boarding I set the phone to flight mode.
Got off the plane and switched it back on, turned off flight mode. No longer acquiring connectivity to mobile network.
So.. went into Android testing (*#*#4636#*#*), turned Radio Off and set it to GSM Auto. Turned Radio back on.. still nothing.
Went into settings.. Mobile Networks > Network Mode was suddenly changed into “Global” and could not change it into anything else.
Factory Reset the device, again set it to GSM Auto and Network Mode was now changeable.
Set it to all kinds of different settings but it still won’t connect to a mobile network.
Everything else on the phone works fine except mobile networks. So no GSM, EDGE, 3G etc. WiFi does work.
The SIM card is also detected and eg. Whatsapp works fine too.
Does anyone know how to solve this?
Do I have to reconfigure the device or perhaps try a different ROM?
Any help will be greatly appreciated!
Grazie,
Steve McQueen

Thnx for your reply RBeavers!
I did consult the SIM MOD thread.. My issue is a bit different though.. My Q has no network connectivity anymore.. at all.
It doesn't drop sometimes and then reboot to fix.
Btw: Its running stock ROM. Might be worth to mention that
Hope someone can help!
Hmmm just installed CM 10.2 .. Set the band to 800/900/1800/1900 .. Set Phone testing to GSM Auto.
Mobile Networks to connectivity to GSM/WCDMA Preferred.
Still outta luck.
Can't think of anything else other than a wire has come loose.

Also, getting radio log (as soon as possible after boot) could help to diagnose the issue:
Code:
adb logcat -b radio
Happy days!!
Got it working with CM10.2!! Fiddling around with it. Set band to Automatic, *#*#4636#*#* GSM Auto, Settings > Mobile Settings > Preferred Network Mode: GSM Only
And set Use Only 2G checkbox. Magic.
These settings in the stock ROM wouldn't work anymore.

Hi,
I bought this phone Lg G4 h810, it shows AT&T logo whenever i boot it and the problem is despite of network mode on lte/wcdma/gsm/auto it always runs on2G internet speed and shows E sign.
I am from india and many service providers are still not offering4G internet service. But this phone doesn't even runs on wcdma. My previous phone lenovo was nicely running on wcdma and always showed the sign H.
My cellular operator is idea cellular and i had a word with them, they sent me settings and all and help me input the settings manually too, but nothing worked.
I checked even the frequencies, idea cellular is offering UMTS B1(2100) and UMTS B8(900 gsm). I checked this on LG website and these bands are compatible with the phone i bought, but still i can't get anything more than2G. Why so?
Plus there is one more problem, when i switched it on for the first time it showed update available And when i tried to update, it showed error and now always there's an icon on top left corner of phone saying couldn't install system update. I tried restarting and updating the device many times, but it's still the same.
Any help is much appreciated.
Thanks in advance.
Have you put your Company APN?
Yes i did, the company executive even helped me to manually save the settings to run the internet in a 3G mode. But all efforts in vain.
Did you solve the issue?
Anything new? I have the same problem.
I have this problem too
Try hidden menu with *#546368#*810# and under Field Test menu / Modem settings if there is VoLTE on/off chose VoLTE and restart. I have done that and my phone starts working with 4G. Don't forget to set up good APN if it's not automatically set by network provider.

Hi
Under VoLTE there is another entry named "Session" and in there
RPR(on/off) switch
I enabled it and restarts but it is again on 2g
Anyone further on this issue??
I have this problem too
I was flash the stock firmware,custom firmware customizing the build.prop,changed the settings in the engineering menu *#546368#*810# disconnected volte,changed LTE bands forcibly. Nothing helps,dont work 3G LTE - 2G only(. I realized that I need to re-flash (change) the original QCN file for H810 and re-register IMEI , but I can not find QCN it freely available.
Hello there, i had the same issue. The fix that worked for me was searching for network manuallly and reconnecting again to my carriers LTE network. Worked as a charm. The issue maybe was a brutal handover as I had been travelli g from a city to another one 200 km away. So somehow I had been disconnected from the LTE network and left stranded in the 2g one. Try it it should work
