[Q] network problem after rooting installing roms

The other day I took the plunge and decided to root my phone and install some ROMs. It was all going well until I started noticing that I wasn't able to make/receive calls or texts. I had gio pro 1.4 installed when I first noticed this problem and I had read that installing cyanogenmod 7.2 had helped someone with a similar issue so I installed it.
Now I have cnmod 7.2 installed with the same problem and with my carrier name changed from virgin to bell. If I restart my phone I am able to call and send messages for a few minutes but then craps out again.
Hopefully someone can help me
Thanks in advance!

no network problem
unfortunately u are having the same issue as me you have to select use 2g only which is only good if you are on a network that supports 2g the nv data file become corrupt somehow and you lose 3g capability i am trying to figure away to fix the gio but to no avail right now

Actually I found out why I was having this problem recently. Turns out I have a different model of the gio (gt-5660M) . When I installed gio pro 1.4 I completely overwrote my stock firmware including the baseband so it screwed up my network settings. I had to find my stock firmware, flash it using Odin and then I just installed clockwork recovery and flashed cyanogenmod 7.2 using that. It's been fine working since then.
Thanks anyway!

well atleast your lucky i restored my original software and it has the right modem when i do a network search it picks up the 3g networks just wont connect to them

Yes, I accidentally did the same to my GT-S5660M. What I did was reflashed the stock ROM and then rooted, installed CWM recovery, and flashed a custom ROM, being careful not to override the baseband. Thankfully the ROM I flashed used CWM recovery and not Odin, and I didn't have to worry about a thing.

[Q] No signal and needs to reboot the phone

Hi Guys, I have a E988 HK version 10D Stock Rom. I found the signal is not stable at all.
As my mobile carrier does not support 4G, so have seleted the network to 2G/WGCDMA.
I found the phone lost signal completely and then it has an error saying sim invalid, but when I reboot the phone, the signal became good again. This is very painfu as I needed to reboot my phone a few times a day.
Can someone give me an idea please? Thanks.

Sounds like modem problem try to install a different stock rom or a new modem

[Q] FreedomPop- no data with Cyanogen, data with stock

Hey guys,
I am trying to get my Galaxy S3 working on the Freedompop network with BYOD.
I flashed to stock firmware:
MD4_update_FULL_Odex.zip
because the MSL code (##786#) that I was supposed to use to reconfigure the radio to Freedompop's network, did not work in CyanogenMod.
In the stock firmware, the code worked, and I got cellular data and voice. However, when I flashed back to CM, the Sprint icon is orange, and I don't have data connectivity any more.
This is the version of CM I flashed to:
cm-11-20140708-SNAPSHOT-M8-d2lte.zip
Any ideas for what could be wrong?

Same with Carbon, but in carbon if the preferred network is 3G, or 1x, it will connect to those networks but it will not connect to LTE. I also noticed that in carbon it connects to LTE and 1xRTT instead of LTE and 1x800. Also does anyone know any possible way to go to 4.1.2 stock (from stock 4.4.2 KK)? I am also on FreedomPop btw.

Found A Fix
I searched a bit and found a fix, that didn't work at first but worked if you use it a specific way. It's the APN causing the issue. This was found out by user Merudo here on XDA. The fix is to do this:
1. Download a Ting APN fix .zip
2. Go on the ROM with working LTE (stock) and take it's apns-conf.xml (it's in /system/etc/) and copy it to the computer
3. Replace the apns-conf.xml in the Ting APN fix
4. Copy to phone with ROM and Gapps
5. Flash it in right after you flash your rom and gapps (e.g. 1st flash your rom then gapps then the APN fix)
6. Reboot and setup and it should work.
Again Kudos to Merudo for figuring this out.

Anyone get note 3 working on here? I'm on boost now with on 3g.. wondering if I can flash just a uicc card to freedom pop lte??

[Q] Network issues after installing DN3 rom

Heya,
So this week I had some issues with my efs partition (phone got boot stuck). Took me a while but managed to solve it by creating a new partition with some commands I found in a guide.
After that I installed a custom rom (DN3) and phone turned on (!!! big success so far).
What I noticed is that my phone allows me to call only emergency numbers. Wifi works fine.
An exact description of what happens:
* When I set to automatic network search - it shows the network bars but without the H sign with arrows indicating it sends/receives data
* When I go to manual and click on my mobile carrier (Pelephone) it immediately says "Registered on network" - and after that still no H with arrows, and I get a network message saying "No Service. Selected network (Pelephone) not available"
* Internet or sms/phone calls not working in any of the choices.
Here is what I have tried so far:
1) Switching properties in mobile network to 2g/3g and automatic network search / manual network search
2) I tried adding APN
3) Installed different rom (Omega V29)
4) Installed 4.3 rom (DN3 version 3.2) - still didn't work. then installed modem (MJ9) and dMK4kernel as described in this guide
5) I tried installed the stock firmware (downloaded from Sammobile)
6) Tried installing XXDME4 Modem
7) I tried of course inserting current sim to different phone and other working sim to this phone - so the problem is not with the sim.
8) Made EFS backup and restored it - not sure why this should work as it seems my EFS is corrupted somehow, but tried it anyway
I am currently using DN3 v5.2 rom
I have CWM recovery
I made EFS backup (though after problem started - as my phone had more serious problems before)
I am rooted
My imei is reading 0049 - i saw in some posts that it means something is corrupted...
I tried searching for threads in here and on other sites, only thing I haven't tried yet is changing imei and I understand thats illegal in some countries + in XDA-Developers, plus it can be very risky - so please any help besides that would be appreciated.
Please help... No idea what to do now. If you want me to download something please provide the link
Thanks!

Have you taken efs backup before installing the rom? If yes then restore it. Google for how to restore efs backup.
Sent from my GT-N7100 using xda premium

No, don't have efs backup from before as didn't have any means of making it

Anyone?

volte in zui 3.1.117 deodexed/qpst

Hi, I am using my Z2 with deodexed 3.1.117 and earlier I was using it with stock zui 3.1.117 qpst flashed. The problem mostly occurs when I use the portable Hotspot. After turning off the Hotspot it is still shown as ON in the notifications and when I restart my phone in this condition I loose Volte. Also this problem occurs when I try to restart in case of some other network related error. And once the Volte is gone, there is no way I can get it back like restarting etc. What I need to do is to flash the modem again. I am currently using the 3.1.117 baseband. Someone please share his/her trick to get back Volte...if possible without flashing the modem

Try to start it from the"Start"
Flash qpst rom of zui 2.5.104 from your pc
Check again the portable hotspot and Volte, they'll start to work again.
Unlock the bootloaders, install latest twrp, then head towards installing any new rom you want !
( I Have followed the same trick and it worked for me pretty well !)

As I have mentioned in my post, Volte comes back after reflashing the baseband. And this problem persists from the day I received the phone from China. And it came with marshmallow rom. All I want is some trick like in some phones when we add new APN the Volte automatically gets restored. So, what I want is some trick someone know for a problem like I am facing. Thanks.
