[Q] Flashed new ROM, now no Mobile Data - Galaxy S III Q&A, Help & Troubleshooting

I searched other threads but found no solution.
I flashed from RRemix to Cyanogenmod and lost my Mobile Data, then went back to my Nandoid backup and everything was fine. Then tried a newer version of the RR Kit Kat and lost Mobile Data again. I went to the backup of my older RR Kit Kat and it works fine. Just curious what the issue is, I would like to be able to switch or update ROMS.
This is for a GT-i9300 btw.
Thanks!

After installation of new ROM take out your SIM card..Boot your phone>power off> Insert Sim card boot again.
I believe the APN settings is not proper. If still not worked then you have to call your SP and ask to send APN settings to your phone. It should happen automatically but may be once your phone register to SP, then SP unable to understand the phone model and not sending the settings.
Try to enable plain mode and disable

You can also Google your apn settings and set them manually lots of roms don't set them and you need to do it manually.

Data issue (solved)

Ok here is the story.
I got my wife a used phone. I went to activate it and I selected my phone. After activating the used phone at spint.com which deactivate my phone I realized dooh I did the wrong phone I reactivated my phone again. I was running CM 9.0 on my phone which is hboot 1.4. I lost my data but my phone part was working. I installed a stock rooted ROM and called sprint. I had to update my profile. After that I had data back. Ok I'm good now, so I thought. I CM 9.0. Restarted my phone and loaded up CM 9.0. No data again. Pissed I was. I tried to clear my cache a multitude of time and still no data. I reinstalled the.stock root ROM and I have data. Does anyone know what I need to do to get data back on CM 9.0?
Pre thanks.

Did you do a full wipe when re-flashing CM?
try configuring your APN settings in Settings/Mobile Network/APN Settings.
I did a full wipe I will try to configure the APN today.
(EDIT) Well i decided to try now. There is no APN setting under moble network. I checked under stock sense and CM 9.0
Thanks for the replys
Ok here is a little update.
There must be something different in the way ICS stores the phone data that CM doesn't pick up on. Here is what i did.
I decided to install a GB Stock version. After the install I updated my profile again. BTW i had data with the stock GB. I waited about 5 minutes after that to allow the system to settle. After I performed this I decided to restore my CM 9.0 backup. Cleared cache as i did before. Loaded up CM 9.0 and bingo data is back. Not to sure were the issue lies in ICS but will dig into that later. If anyone has an issue similar to mine you can give this a shot to see if it clears up your issue.
Thanks again for reply

[Q] Lost automatic connection with my data plan

Hi everybody!
Yesterday, I applied a custom rom to my Galaxy Note and after a successful installation, my data plan wasn't working like it used to be.
I have to say this isn't the first time I have done this, and in the previous opportunities after flashing the rom and rebooting, the EDGE/3G icon appeared by itself detecting my data plan. I never had to configure the APN settings (like it is said in many posts I have seen here).
So, when I realize that it wasn't working properly, I re-flashed the rom but didn't worked. So then, I downloaded the ICS stock rom and flashed it through Odin, hoping it would reset all things here and would give me the initial configuration, but that didn't work either.
I have entered through settings and deactivated/activated the options related to mobile data, but that icon never appears or my data connection showed up.
Forgot to mention that this phone was unlocked through cellunlocker by code, and that I can make phone calls with no problem and also the Wifi works fine... And thank you in advance for any advice/help that you could make
If it's happening with different ROMs then take a look at your modem (baseband). Are you using I717UCLF6? Go to System Settings-About Phone-Baseband Version.
Like ^^^^ said, and you didn't say it, but I'm guessing T-Mobile. So flash any ROM you like, reboot and let but settle in, then flash the Blaze 4G or whatever T-Mobile modem works best for you.
You did enter your APN info?

Verizon Note 2 to page+

Ok im at a loss and need a tad bit of help.
I have a Verizon Note 2 (i605) flashed to page plus. When I install a custom rom i lose mobile data says disconnected. But when I restore the stock rom it has mobile data. The stock rom seems to work fine for everything calls,data,text. I have tried Carbon, Cm10.2 nightly, Cleanrom, and a few others they get calls and text but mobile data says disconnected. What do I need to do to make this work. Do I need to change my apn settings everytime? Will changing the apn settings even work? I bought the phone on swappa and im very happy with it but i do want to enjoy it like my other phones. Do I need to put in a sim card in didn't come with one and as far as i can see it works without other than my issue here.
Anyone?
Hope you flashed new rom with cwm

Yes
I imagine that page plus uses a different apn then vzw. U can backup your stock rom apn. Check the market for a app to do so. Then restore it after u flash the new rom.
Did that with no success. Attempted manually entering the settings and no cake.
Same issue here. Custom ROM = No data.
Does anyone have CM 4.3 on page plus working with data?
will someone chime in please.
Still doesn't work. Any ideas? My brain hurts.
still not working.

No mobile data with CM12.1 Stable( 19.11.2015) from Lolli. - Do I need bootstack?

I am new to this forum, but I read so many hours and thanks to this great forum I was able to flash cm12.1 on my LG G2 mini(D620r).
This is really a great rom, everything works very good. except one detail: mobile data, I have the "!" next to the symbol.
I used cm12.1 for some time on my Samsung S2(I9100, CM12.1 with Dorimanx Kernel and Stweaks to change settings) and I missed it so much when I got the g2 mini with stock rom.
For the LG I really had to read a lot(english is not my native language) to understand everything. The CM12.1 for S2 was much easier.
I did it this way:
LG G2 mini(D620r) Stock ROM Android 5.0.2 (should not have done the update from KK)
1.root
2. unlock bootloader(patched)
3. Custom Recovery TWRP v2.8.7
4. wipe everything except internal+sdcard
5. flash cm12.1 stable + gapps pico ... cm12.1 works perfect.
except mobile data, I did notice this very late, cause I used the g2m only with wifi.
I tested different APN settings, but I could not get a mobile data connection. (it tells me that it is connected sometimes, but it does not work)
I put my SIM card in a lg g2 with stock 5.0.2, works perfect. same with my old samsung s2 cm12.1
"CM12.1 does not need any bootstack in the latest version" is written in the CM12.1 Thread, first posting.
Could it be that something went wrong and I have to install the KK Bootstack because I am still on L?
is it possible to do this now and than SIM works again as it should??what else could I try?
I tried some other versions: 28-12, 30-12 and 01-01-2016. with all the same problem.
I read in a german forum about a guy with same problem(but other smartphone), he installed cm12.1 at least 10times, also different releases ...finally for him a different baseband worked. But I know not much about this...
Thank you, I am sure someone in this great forum knows about this problem

Hi. Your problem is very specific. I have D620r too, and no problem with mobile data. But I use KK bootstack. You can try flash Carbon rom which is based on CM 12.1 or try this version and find out, if problem is there too. Be sure, you format system, data,cache for clean installation. If problem is still there, you should try KK bootstack(recommend as last option). Maybe somenone else will help you, I really don't face this problem.
Good luck!
Thank you, I already tried bootstack v1.5 KK 5min ago. I still have this problem.
When I put my sim card in the s2, I get some sms from fyve(vodafone) and apn is set up and so on..nothing like this with the g2m
I will try to get some other sim cards an look if there is the same problem.
and will get carbon rom...but it is be not so much different??
does anyone knows somehing about this baseband thing?
EDIT
Carbon Rom does not work. ;(
I will go back to cm12, this should work
I flashed CM12 and now I have mobile data connection again. seems to be a problem just with cm12.1!
But if anyone knows what could have been the problem please tell me, i have a full backup and would prefer to use cm12.1
thank you
Omg, something went terrible wrong.
I installed a ROM(DroidMaster Lollipop-lite) and thought I also would need the Bootstack for L.
So I restored the backup(Druidmaster) and the bootstack...no I lost the IMEI, WIFI MAC adress ...there is nothing left^^
The system boots normally. I have done a backup(TWRP) of the system, should still be there.
I will try this.
please tell me if there ist any hope to restore this g2mini???

as i know you dont need flash right bootstack on newest cm12, you can flash it on kk or l - no difference.
take it easy, flash stock fresh http://lg-phone-firmware.com/firmware-LG+G2+Mini-Tutti-57.html by lg flash tool (you can find easy some tutorial), for example v20a or v10.. (first is lollipop second is kk) and make every step again.
Droid master you can restore only when you was on L and will be no problem. If you need CM12 just install fresh kdz file of kk, root it, unlock bootloader, install twrp then cm12 and will be ok.
I restored my backup of cm12.1 because I was worried about the missing IMIE and baseband. After the Backup I had my IMIE ... again, everything works except mobile data.
I don't know what exactly is the problem: mobile data works with every ROM except cm12.1 (no matter which version I take.). I would like to report this problem in the cm12.1 thread but I don't have permission(not enough postings) maybe someone could help me. because of all ROMs I like cm12.1 most.
I will install cm12 and look how this works and if there are any bugs. If I don't like it I will go back to stock with the flash tool 2014 and kdz(already done this once)
thank you

In CM 12.1 go to settings >> mobile networks >> Acces point names (APN) and if you don't see there nothing, you have to configure it. In google find apn settings of your mobile network provider, some guide or tutorial and configure it or just remember apn settings from work rom. Good luck.

No mobile internet after Rom flash

Hi,
I recently changed my ROM from Cyanogenmod (some of the last nightlies; so Android 5.1.1) to a custom rom called "existenz".
After successfully flashing the 6.3.5 Premium Update to my phone, the mobile data stopped working correctly.
Whenever I try to enable mobile data in my settings, the trigger simply goes back to disabled.
Reason for ROM change: I didnt want to use nightlies anymore and this ROM seemed perfect for my phone.
I tried several restarts, but nothing changed.
I flashed the ROM with TWRP.
Thanks in advance,
Pascal
(If nothings helping, whats your custom ROM you could suggest me?)
I flashed the latest nightly of cyanogenmod again. Mobile data is working now. Guess I'm never leaving cyanogenmod.

Are u sure u enabled ur APN settings from settings/more/internet settings?
For ur information only CM roms will enable Internet Apn automatically after flashing rom. Sony custom roms did not enable Internet APN automatically. We need to set it by ourself or u can install internet APN from settings/more/internet settings
@Rajeev
Good point. I read something about "allow only IPv4" - so I changed that - rebootet my phone but still nothing.
I cant remember tho about anything saying its disabled. Might give it a second try then, havent fully configurated my phone yet.
Thanks.
Only turn ON internet data and go to config / •••More / internet settings- Download settings for Internet and MMS
