Cellular data not working on cm12.1 - Galaxy Note II Q&A, Help & Troubleshooting

Hello, I used a guide outside of xda to flash cm12.1 on my note 2. (GT-N7100.) (To find the guide, search how to flash cm12.1 on note 2 on google and click on the link that says [CM12.1 For Note 2 (Stable ROM) - Information Lord]. I can't post links because I have under 10 posts.) I already tried the fix cellular data guide in the thread, but the terminal emulator thing told me that it was an invalid IP address.
I'm not sure if this is needed but I flashed using Philz. I got it to work yesterday by deleting all the APNs. I then installed the wrong gapps so I had to wipe everything again, and then I tried to delete the APNs again and now that solution won't work for me anymore. I can make calls and texts, just cellular data doesn't work. The status bar shows the signal bars, but with an exclamation mark. However, when I'm connected to wifi the exclamation mark disappears. If I have wifi on but it's not connected, the exclamation mark comes back. I've tried searching everywhere on how to fix this but nothing works for me, that's why I resulted in posting a thread.
Any way you guys can help me? Thanks.

Sorry, forgot to update the thread but I fixed it.
I just added my own APN by searching APN settings for my carrier and now it works
Thanks for the help though.

Cyanogenmod 7 cannot connect via mobile data

I am having issue in connecting mobile data, although I have the "data enabled" option ticked, but there is no mobile data icon appears on the status bar.
I googled and tried lots of apn setting for my carrier however none of them can solve my problem. I have done the "search automatically" method under network operators. Also, I have tried flash newer cyanogenmod nightly and other radio version over my original cyagenmod rom, but none of these help.
Please advice on how could I get my mobile data working again.
Mobile data issue
I am facing the same issue . Any one knows wat could resolve this??
which radio version r u having????
Hope I can help you
Quoted from CM7's official thread for HTC wildfire (Buzz):
If you have any issues with GPS, 3G or any other network issues, try flashing the following radio firmware. NB, it's not possible to flash this zip from ClockworkMod 3, so if you have this version installed, use ROM Manager to flash it instead.

I deactivated my 3G subscription. Deleted the APN. Activated 3G subscription. Recreated the APN and voila I am connecting via 3G. I hope this would help others facing this issue as well.

Hi,
I have tried all three radio versions, flashed all 3 of them several times for the last 3-4 days but I am still not able to enable the functions of GPS & Mobile Data (Internet) on my rooted HTC Wildfire. Currently I am running Cyanogenmod 7.1.0.1.
I am really going crazy over this. In google maps, location is found only while using wi-fi. With GPS location is not found although the GPS icon comes in status bar. Mobile internet doesnt work at all.
Please help.

As a last resort (this will do a clean wipe of all data) -
Run an RUU for your phone
- Downloaded from android forums.
- Connect phone to PC and run RUU
- This downgrads phone OS to eclair (android 2.1)
- Let it do the bizniss
- Re-root with unrevoked 3
- Re-Flash CM7 and gApps

[Q] Can't send sms and greyed bar after cm 10.2

Hello fellow xda members. Well after searching for a solution for my for nearly a week now i figure i should post the question to see if i can get an answer. I did search around before hand and tried many solutions but to no avail.
Background, I have a sgh-t999 that's apparently unlocked since I've been using a fido sim card in it for several months now. when ever I'm running cm 10.1, I have full network access, texts, mms, 3g data, etc.Note: d2mtr is flashed to my phone and my model number gets changed to sch-r530, baseband: t999vvllh2.
After flashing to cm 10.2 RC1. d2mtr. I get stuck on the metroPcs network with out any way to manually switch network operators because the option in mobile networks is greyed out. Everything seems to work fine in terms of calls but besides being able to receive texts messages i can't send them. The signal bar seems to be empty or greyed out yet it still picks up 3g data. I've vigorously checked my apn settings to no avail. deleted the voice+ apk since I'm not in the US being in Canada and i'm all out of options right now. If i restore back to my previous backup ,everything works fine and i did check to see if I loose my imei number after flash.
I previously tried flashing d2tmo to my device but to no avail, assert errors. It would greatly be appreciated to get a response and thank you in advance for any help.
Edit: It's a sgh-t999v as printed behind the battery. I followed this guide http://forum.xda-developers.com/showthread.php?t=1775616 hence the reason why I'm coming from ICS. Looks like I'll have to reflash using ODIN which i was trying to avoid out of fear of bricking but it seems like my only option now.

Might not be the right ROM for your phone. Or it could be buggy. I've messed around with a few and finally found a great one that seems to be working well for me. I have the d2ltetmo. I'm running Liquid Smooth ROM with 4.2.2 and TWRP 2500 recovery. The ROM roots your phone as well. Any questions feel free to ask. Hope I can help!:cyclops:
I wouldn't flash D2MTR Rom to D2TMO. Too many differing things. There's a CM for D2TMO too.
Are you sure that's a t999? The baseband looks like the one for the t999v.. And it also looks like you might be on ICS firmware.. What I suggest you do is check the model number of your phone to be sure what model you have, after that update to 4.1.1 or 4.1.2 via Odin but make sure its the firmware for your model. After this flash your custom recovery, and then try flashing cm10.1 for d2tmo.. If your device bootloops after you Odin, enter recovery and do a factory reset.
Edit: check the model number by removing the battery and it will say at the back of the phone.. And the firmwares to flash in odin are in the development thread

Well after a long process of flashing stock jb then finding a proper method of flashing cwm since i had difficulties with fastboot and went with the dd if-of method using the terminal emulator. I am finally on a stable cm 10.2 rom, d2tmo, where everything seems to be working and intact. Thanks for the advice now i have the long process of restoring my apps and data and what not with titanium backup.

elephone p8000 can't access network or google play neither via wi-fi nor cellular dat

Hi there,
Excuse the novice. Just got this 2 days ago and I am still trying to figure it out why I can't access the net at all.
I have not got Android experience much and I am digging now how to come out of this situation.
So no option to access Net at all. The Error in response is " Couldn't sign in. There was communicating problem with Google servers . Try again later." So this is like a loop there.
Android Version -5.1
Baseband Varsion - MOLY.LR9.W1444.MD.LWTG.MP.V16.P10
Kernel Version - 3.10.65
Build Number -ALPS.L1.MP3.V2_NB6753.65U.L1_P22
Custom Build Version - Elephone_P8000_20151014
I must admit the Phone came preset and once I have switch it on it picked up GMT time without I have set anything.
I will appreciate any help or pointing to a resources to try to solve as now it is unusable as I can't download anything.
Thanks in advance.
Check:
Settings --> Data Usage --> (cellular provider tab) --> toggle 'enable mobile data'
See if that's the issue. Good luck.
Now Stacked to The Elephone Logo on and unresponsive.

Thanks kevvyboy,
I can't do anything right now. The phone by itself (really) got in a mode I can't read even with letters so small, went to the Android Man with red Mark and now is in front of me unresponsive with the logo of Elephone totaly unresponsive.
Just to underline - I have not touch anything- I have left it on stand by last time I have played with it.
Any clues and help please will be much appreciated.
PS. NOW I have managed to (I guess Switched it off) and again on and there was window with APP UPDATE - came to 116 out of 116 updated and now again can't access the net neither Google Play.
Could this be a OTA Update completed somehow?
Thanks everyone in advance!

Hi again,
I have enabled the cellular data - no luck again.
When I am trying google play again message Google servers can't be reached and the more interesting - using the - preload browser it try to search trough yahoo search. This phone was sold to me as new, but I am starting to wonder what it has been through before it reached me?
Will a flash using PhilZ Recovery will help?
Could someone point me the way out of this please?
Thanks!
New bizarre Message.
Hi again,
Just to make it more interesting out of the blue it Popped up a Message box with following wording.
"In a Previous Android Version You have disabled all Google App services. Do you want to enable them. Yes/NO,
Of course I have chosen Yes and Again Can't reach net neither via Cellular data nor Wi-Fi.
Any useful contribution will be much appreciated.
Thanks!
Stuck on Airplane Mode? Try toggling it on and off. I remember my HTC OneX having an Airplane Mode issue - had to toggle on / off several times and reboot.
ETA - faulty APN settings for your provider? May explain a mobile data issue, but doesn't address the wifi issue.
Dammit.
Got It Work on Cellular

Thanks Kevvyboy for your contribution.
Somehow I have managed to get the Cellular data connected and now have updated the Google Service.
WI-FI still an issue. Is there any sense - updating a driver (if I am not asking stupid question here)?
Thanks!
Glad to hear at least cellular working! The wifi issue is a bit of a mystery to me though - I'm all out of smart ideas, sorry
Hopefully some other bright soul can chip in.

download drivers for SP flash tools and SP flash tools program.
go and download mediatek drivers and sp flash tool.
you can get these from elephones website, google or where ever. i got mind from needarom. i used the latest versions for both.
i downloaded the 5th November 2015 firmware from elephones rom. it came pre 7-zipped. i unzipped it and left it's structure.
installing the drivers part:
you need to disable signature enforcement in your OS to install the drivers.
open SP flash tools.
load the scatter file in the official rom folder you unzipped with 7 zip.
at this point press the download button in SP tools.
switch off your phone. connect the usb cable to the phone and the computer.
you should now have the latest firmware on you phone when complete.
please note it wipes everything, so back up anything important to you.
once done, set up your apn in settings, mobile networks, access points.
wifi should work after a clean factory reset if you don't have a dodgy device.
elephone only supports 2.4ghz for wifi as far as a i know.
also make sure your network bands and are supported by the p8000.

Hi El_Nino9,
Thank you for the reply and sorry I am delaying my response. I have actually done some of the suggested previously once I read more on the site - thanks for the contributors here. I had Eragon 9.5.0 Custom ROM set with Philiz recovery tool after Mediatek driver download but the wi-fi is still an issue.
I will try to perform the the one suggested from you, I just have located the latest Elephone p8000 ROM on the Elephone site and will perform this on a first chance I have. - most probably on Friday.
Thanks once again and I will post an update from the outcome.
OK!
I have done the upgrade to the 05.11.15 Stock ROM.
Have made a Factory Reset and the Wi-Fi is working as before but I can't reach internet basically.
Again after attempts to get to Play Store or to or to perform a simple Google Search it comes again after message "Just a second" and after 20- 30 seconds it end up with the message.
"Google Server can't be reached at the moment please try again later."
Any help on this will be much appreciated!
Thanks a lot in advance!
P.S>
I have just discovered that the icon of the WI - FI showing a processes going on but I can't reach My Router URL for example through the Local network.
Does it mean this is really dodgy unit or I am missing any settings or there is any cure for this?
Thanks again!

so your mobile data still works on the latest firmware? specially after typing the correct apn settings?
regarding your wifi, where is the router in relation to your position? far away? standing right next to it with the phone? whats your encryption for your wifi? tried changing that to a different type and seeing if it connects?
if you have big concrete walls and live in a nice solid building that may too cause signal not to reach. the wifi isn't that great on the device speaking from experiance in comparison to other devices.
if all fails... possibly dodgy device

Hi EL_Nino9,
I guess either the p8000 not like my D-LinkDIR-655 router or I am missing something in general.
I have an extension for the other rooms and the phone connecting to a simple TP-Link with no hassle at all, but D-Link is like a brick wall - you see the wi-fy working but no internet access.
It is still a mystery.
At least is proven the wi-fi module is working.
Believe me - I have tried to alter the setting on the route and still can't get to the net content.
Will keep exploring this and will report if any luck.
Thnaks!
I´m facing the same issue here. Google-Services like Google-Photo, Gdrive, Inbox are not working. Any solutions so far?
Looks Like I have rooter WI-FI issues

Hi kraftmaschine - I have discovered that my aged D-LInk DIR-655 was giving me problems dropping out the signal. I had an access through mobile network and through my other room extension rooter, so I got on mind either compatibility issue or router problem. So I have upgraded the router and voila. Everything got sorted.
Also upgrade to the latest mod - not OWA but using the standard methods described here.
Hope that helps.

Sprint Note 4 on T-Mobile Network HELP PLEASE!

I recently unlocked my Sprint Note 4 and I have a T-Mobile sim card in.
APN settings are correct, I made sure, but I'm not getting any data. The bars only show an exclamation mark. I have called the service provider with the issue and they send a signal. Yet, the data will last for about 5-10 minutes before it goes back to the exclamation mark as stated above. I am ABLE to make basic calls and texts only. My initial idea was to flash a T-Mobile modem, but I keep getting an error while trying to do so through Odin. My set up will be listed below.
- Stock ROM Rooted
- TWRP Recovery
- Android Version 6.0.1
I have no idea what to do from here, so if anyone can give me some insight or even possibly walk me through what needs to be done it will be greatly appreciated. I am going to attach a screen shot of the error I got on Odin when trying to flash T-Mobile modem.

WiFi broked

Hello guys, a year ago I tried root my phone and got bricked. After 2 weeks I finally fixed and came back to the stock rom. Since that day my WiFi is not connecting.
I'm able to search and find any network, but when insert the password, the phone try to connect, the signal go down, the message "connecting" appear, and after that appear as "saved" but not connected. I already tried to define a static IP address, but didn't work.
Can I broke the wifi firmware when tried to root for the first time?
Someone have an idea on what is going on?

Follow the unbrick guide method 2. Make sure you follow it right.. Don't skip any parts because it doesn't work. Don't see how you bricked the phone by flashing SuperSU but okay..

Hmm, if that and the unbrick isn't working then you might want to ask yourself it something is broken. Does it connect to other networks?

No I ve used several different hotspots to connect. The strange thing is that mobile data are working.
hmmm take a look at this thread:
https://forum.xda-developers.com/oneplus-3/how-to/radio-modem-collection-flashable-zips-t3468628
If that doesn't work try to flash ex kernel if i remember it correctly it changes something with wifi to.
If that doesn't work then It's broken or you can fix it by doing something else but dont know what, Good luck
