Hi, i am facing a problem regarding my lovely Droid Maxx. I accidently selected the USA band in radio frequency band menue while data connection was enabled and i was browsing. And after that my mobile lost the network signal and it shows that "No service". There are two selections in this menue i.e USA and CELLULAR.I tried many times to select the CELLULAR band and it also shows that the CELLULAR selected successfuly but no signal at all.However Wifi,Bluetooth and Gps are all ok and in working condition.Mobile is not rooted yet.Please help me to get out of this situation.
Thank you...
The problem was solved by re flashing the firmwear

My father is using Tab2 (P3100). Running Stock OS, Unrooted. 3G Data Connection from Vodafone Delhi India.
since a month or so back he found a update notice and upgraded the Stock Firmware to Latest 4.1.2 using WIFI
Not sure but might be since then, Whenever he's On Roaming, Data Connection Won't work.
Currently He's in U.P. circle it won't connect, Voda has 3G Service here, And I use it everyday at home/city wide.
Tried following:-
1). Checked APN Settings, they are correct.
2). Checked Data Roaming in Mobile Networks.
3). Tried Switching to GSM Only, and WDMA Only, WCDMA/GSM Auto Option, All options same result.
4). Checked wifi is OFF, and Data Connection IS Enabled, using Widgets or APPS but it won't turn on
5). Took out the SIM from Tab2, and Inserted In my Android Phone and 3G/2G Connects Instantly.
6). Put A different SIM which is from my Region but as its not On Roaming, Data Works fine.
7). Checked with operator they have no clue whats wrong in the TAB.
8). Requested Fresh APN Settings from Operator and saved it, But Tab2 won't connect.
Can someone shed some light if this is a BUG in current latest firmware of Tab2 or I am getting and my brain fails to finds a solution.
Any help will be appreciated, don't let me down my fellow members pleaseeeeee
Hello,
I know there is a thread for this in Galaxy Note section, but i feel i need to share this for OPO community.
I'm using OPO v33 rom. I live in Mumbai and have a 3G vodafone postpaid corporate connection.
Recently i have been to my native mysore on few occasions, and everytime i have seen the 3G data getting disabled even when the data connection settings are enable on roaming.
I never faced this issue on my nokia lumia 920 which perfectly latched onto roaming and 3G data was available.
On roaming, with OPO, the data gets disabled and i dont get a specific "E" or "H" sign with + noticafion.
I only have the signal bars with small R icon on top of the bar.
Please let me know if there is a workaround for this.
I have also seen this issue on v25 rom aswell.
Note: i have tried setting connectivity to automatic in mobile networks.. and also tried to select the specific Vodafone network. both didnt solve this issue.
Another interesting thing while on roaming: my nokia 920 recognised 2 networks for vodafone.. one with 2G, 3G and another with only 2G. and i could select the first one .. and 3G was getting enabled without any issues.
i think that E and H as well as H+ is only something you can geti n your own country. When roaming, it's always the default for that service prodiver in the country that you will get.
Someone brought me an LG G2 D801 and I'm having issues to connect to mobile networks. I could a couple of times connect to LTE (with weak signal) but never to EDGE or HSPA. I've selected 'GSM only' and 'WCDMA only' options, entered the 3845*#801# menu, checked my APN settings... I also tried rooting phone and installing CM12.1, but the same behaviour persisted.
According to phone specs, this phone is compatible with the network bands available in my country (Argentina), so I'm a bit lost right now. I'm thinking on doing something with QPST or similar.
Any idea would be appreciated =)

You said your rom is not rooted? That probably means the default network settings for your phone is LTE/3G/2G. That option will look for the best signal you have in your current location, then it will choose that data network i.e., EDGE .
It seems like your 4g/LTE signal is weak on your vicinity Perhaps, if you could force LTE (by rooting and installing Advance Signal Status app from Playstore [Device Info >Set Preferred Network Type > LTE only) you can have at least lte reception. Unless, 4g is not available in your area
Try going outside your house, and find open spot and see if your device was able to detect it.
Just let me know if you still have some concerns. Cheers!

Same problem for me. Same galaxy s6 model and same original android version 5.1.1 (g920fxxu3q0kn)
From a couple of days it doesn't connect on lte. But the big problem is that if I choose lte/3g/2g it doesn't connect neither in 3g. I have to force it to 3g only to let the device connect back to internet.
I don't know why but when I came back home, if I switch back on lte/3g/2g, it connect back again on 3g (no lte in my home area)
I'm not sure if it is involved with transit in/out wifi spot or some kind of lte cells. I will try other tests next days
I fear it could be a bad bug
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
