[Q] Mobile network not working after flashing (ICS) - Galaxy 3 Q&A, Help & Troubleshooting

So, I tried few ROMs and kernels, but every time I had big problem, my network wasn't working.. Not only data, I couldn't make phone calls or send SMS.
Any experience with that?
EDIT: that happened only with ICS roms, now I'm back to GB and it works normally.

^Do you have "Pin Lock" enabled? If yes, then disable it and it should work fine after that.

^Yeah I meant the PIN Lock. There's an option to disable it somewhere in the Settings, simply do that and reboot!

The thing is, I can't disable it, no idea why.. It says "Unable to change SIM card lock state".
I checked google now, seems like there were more problems with that, gonna check it later thanks

I can`t enable internet in MIUI

After installing MIUI I can`t enable data transfer (2g/3g internet). Data transfer is turning on, but there is no 2g/3g logo and internet. This happens after installing all MIUI stock and custom roms. APN settings is correct, before it was ok. I`m installing via Clockwork recovery v5. Device is G2x (P999)
What should I do? How to enable it?
I believe for the g2x you should see an H next to the bars, that is if you are in a good service area.
Otherwise I think it also shows G, and E.
If it doesn't have anything at all, then I'm not sure.
Does the internet work when you go inti the browser?

I'm having the same issue....
im using rg2x right now and the only way to fix it is with a hard reboot every time i turn my phone back on
try reflashing the faux kernel it worked for me to fix a problem i had not being able to turn my wifi on it should work for you too
what i have a problem is the backupp app does nto work for me im runing rg2x miui by richie
Yah I have the same problem, I notice it works but when you use WiFi then your done w/ the wifi and shut it off the regular cell data never comes back on - You have to completely reboot the phone...I'm using SINGH-UI - same thing

I`ve tried SINGH UI too, as I remember wi-fi is on by defalut, isn`t it? So, I turned it off, and use my phone few days. Rebooted it few times, but data not worked ((
I had this problem before, go to ur APNs and go to authentication and make the authentication "None" instead of "Not set". That will enable ur data

Hey go to SETTINGS->MOBILE NETWORKS->ACCESS POINT NAMES-> in here select option button in your android phone, in the menu select NEW APN, you will get the APN settings as seen in this. In the link ACCESS NUMBER = SERVER in mobile.
As I am not allowed to post link for first ten TIMES! will guide you through
google search -> "vodafone apn address" the third result will be GPRS APN Settings with Username and Password - Modem Unlock. Click it and follow the method above mentioned.

Try using 000000 or 123456 to see if either of those unlocks it. Supposedly these generic codes will unlock it.
Hi Guys,
same problem here. Dismiss button is working until new network registration. 000000 or 123456 codes are not working for me.
It is asking me now, just after I changed the SIM card (same number, just dead old one). No problem before... Any suggestions?
Thanks

Is your N8000 rooted?
If so, try to flash another modem.

Thanks to everyone of you that made an effort on helping me about this problem.
I did a factory reset from setting again and also manually did a hard reset from recovery mode but the bluetooth still doesn't want to come on.
I went to SETTING, ABOUT and STATUS and I saw an available mac address for wi-fi but the bluetooth mac address was Unavailable.
I will really appreciate any help for this bluetooth issue. Thanks in advance.

[MG3] Firmware Changes Thread - If u notice anything new, plz post it here!

I know Samsung doesn't post changelogs for their new updates but I just wanted to make a thread for the MG3 update and maybe future updates to point out the changes in the firmware. If you notice any changes, please post it here and I will give it a "thanks" if I can confirm that it's real and I'll put it in the OP (along with your name of course).

WIFI Broken after MG3 firmware update
Just went ahead with my S4 (i9505) MG3 firmware update via Kies (the firmware update version is PDA:MGA / PHONE:MGA / CSC:MG3 (BTU)), everything installed without a hitch, phone rebooted, AND WIFI IS NOW BROKEN!! Meaning the Quick Toggle remains grayed-out even if you press it to turn it on, and going into System Settings and trying to turn on WiFi from there also doesn't work-- the WiFi is simply not turning on! This is a MASSIVE bug which is utterly unacceptable being in an OEM update!!
I've since restored my NANDroid backup to go back to i9505XXUAMDM. At least the WiFi works in that firmware. Yeesh.

I had the wi-fi bug a few days after I flashed the MG3 firmware (wi-fi toggle, both on settings and quick settings are greyed out and stuck at connecting). If you're running the international version you should flash the latest modem.

As for the Talk back issue you are talking about I have no idea what you are talking about. I have never experienced such thing. Maybe it is because i have my Talkback setting to off.

Ok.. Le me explain a little. I installed No Led and it requires accesabilty option in order to function. When i let it have accesability it turns activates the Talkback function besides of the phone having the Talback function unticked... Heard that also other applications haves the same issue so it is a 4.2.2 issue....

That means that so far I have not had the need to install an app that needs accessibility which then turns on the talkback function.

How to Restore Factory WIFI Settings

Hi all,
I have a sprint HTC U11. I have TWRP installed and the phone rooted via SuperSU. I installed the Wifi Tether Router app and got it to work. However, the app did something to mess up my WIFI and I am no longer able to turn WIFI on at all anymore. It just says "Error" in the WIFI section when I open the phone settings.
Can someone please tell me how to restore all of the factory WIFI settings to get rid of this problem?
Thanks.
You can maybe try Settings -> Backup & Reset -> Network Settings Reset to see if it will help..

I have tried this with no luck. I think I probably will have to flash something via fastboot, but I'm not sure what to flash.

I suppose you have also tried this from their support page (if I googled correct app):
Q: After using the app I can not use WiFi, I can not connect to WiFi networks
uncheck the "Scan Always Aviable" on WiFi Advanced Settings on your phone and reboot your phone

Yeah, I have seen that, but the "Scan Always Available" option is not present on my U11. I know that it was on my Old M8.

I have relocked my bootloader as I am selling this one as Solar Red is on it's way so I cannot test it.
I might be completely wrong, but there is that or similar setting now in Location -> three dots menu in top right corner -> search -> enable wifi scan or something..
I have no other ideas except obvious ones or googled ones, if you uninstalled app, rebooted and still doesn't work you can maybe contact developer or someone here uses that app and can help you..

I'll give that a try when I get home.
I should have also noted that doing a factory reset resolves the issue. I would like to avoid that if possible though.

No, I am not familiar with that process.
I believe that is flashing without wiping, on top of the existing rom install. I'm not sure that this will help; but that is what I've seen discussed as dirty flash....
So this is a conceptual only answer.
I am having the exact same issue. Anyone come up with a fix?
