My internet data frequently disconnected

Hello,
i am back again with a new problem!
All the previous problems that was mentioned in this forum is GONE. i was a happy owner. Until i got this problem.
so i wanted to try new Modem, just so i can increase my Signal, and right now, my data plan is keep going on and off, and most the time i can't get it connected it.
i did the wipe date /factory reset from the ROM manager, and wipe cache and dalvik. and yet the problem is not solved.
right now, am running cm-10.1-20130304-EXPERIMENTAL
and the Modem am currently running which sometimes works ( I747MVLDLK4 ) am with Rogers, Canada, Edmonton, AB
If anyone helped me out with this, your next coffee is on me! for real!

anyone?

When I have Wifi or Signal/Data issues, I just Odin back to stock and then re-root & flash ROM again. Works every time.

Did you use ODIN to flash the stock ROM and factory reset in stock recovery ?

Yes! i think i did a mistake. While i restored to the stock rom, The baseband that i was using it was I747MVLDLK4 and not the STOCK modem. So maybe that is why its not getting connected? am trying to apply the stock modem into the the stock rom, but its giving me Fail error.
am just scratching my head right now to be quite honest and this close to throw my cellphone outside of the balcony.

What type of fail error?
How are you trying to flash it?

i managed to make my modem into the stock version. However am just getting "E" in my data connection. Reminder am still in STOCK ROM and stock modem now. is that a good sign that i slighty getting everything back??
should i just install the CM 10.1 now and see the results or what you guys recommend?

annnnnnnnnd my " E" is gone.. Beautiful
do you guys think it might be a actual physical sim card issue?

UPDATE: i restored my phone into the stock rom by Odin3 and now i just re flashed the Cm 10.1 again. sadly i still have no connection and my income and outcome for calling and texts is also not working.
please help!

Try flashing Task's AOKP and see if you have the same issue. Additionally, try deleting the current APNs (access point names) and manually enter the APN settings for your carrier. Could also just be a faulty SIM card as you mentioned.

[Q] IMEI Oddity

I recently purchased a T Mobile SGH T989 off of Ebay. The seller said the phone was used but in good working condition. When I got the phone, it looked good and had little wear. I went in to settings and preformed a reset to defaults and put my sim card in to test it. The phone seemed to work fine and I tested it for about a week with the stock T Mobile rom. After a week everything on the phone worked and tested out ok. I reflashed the phone to the latest stable version of Cyanogenmod. After first boot and at the home screen, the phone never connected the T mobile service. I re flashed the Cyanogenmod rom thinking something went wrong the first time but again no service. I ran clockwork recovery to the restored the stock rom and immediately get 4 bars or service. Reflash Cyanogenmod rom again no service..back to stock phone works fine. Puzzled I went back to my old phone and decided to call T Mobile support, I read the IMEI off the back of the SGH T989 to the service rep and they told me this phone was part of a business plan that was overdue and was blocked (aka blacklisted). When I rebooted the phone and looked in system info the IMEI had been altered. I reflashed to Cyanogenmod and the phone has the same altered IMEI number as the stock rom but no service. I guess I am confused why it would work with one rom and not the other. Is there something more the governs network provider access? Is there something else I can do to get it to work?
The Ebay seller never said anything about bad IMEI, so I am going to ask for a refund and send it back if I cant fix it...just a better part of a day wasted messing with it only to go back to a Mytouch 4g.

Do I boot into clockwork and perform a darkside wipe and then install the radio from zip?
If I go back to the stock rom will there be any ill effect?
I don't want to have it not work in CM and also not work on stock

You can boot into CWM and wipe cache, dalvik cache and flash the radio. And you can always go back to the radio you have now. To find out which one you have now look for baseband version in settings/about phone.

[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.

[Q] Lost LTE after switching to KitKat

I decided to give Kit Kat another try a few days ago, but since then I have not been able to connect to LTE.
Prior to flashing I was running CM10.2 and my LTE was working fine. I initially lost LTE when I flashed PACMAN. I have also tried AOSB/ProBAM and Beanstalk. None of the Kit Kat roms gave me LTE so I gave up and restored CM10.2, but afterward I was still not getting any LTE connection.
I tried flashing the MD4 modem, but that didn't seem to fix anything. I've also heard that going back to stock could help, but I'd rather not have Knox if I don't have to use it. Which stock ROM here on XDA would be the best (Not planning on using the ROM. I just want LTE and then will flash back to Kit Kat)? Would a different modem fix my LTE issues? Is MK3 better than MD4, or are there any newer modems I should try?
Thanks for the help!

Any of the ROMS that have [TW] in the title should work. Full Knox only comes with flashing a tar file in ODIN, because your flashing every partition of the phone. Modified stock ROM zips do not have knox, unless otherwise noted. Make sure to do a prl and profile update when you flash to stock.

Flashed Wicked Sensations last night with the MK3 modem and I seemed to be getting LTE as soon as that booted. Updated my PRL and Profile, and then wiped. Installed AOSB again, and I seemed to be getting LTE until I rebooted. After the first reboot I seem to be stuck in 3G again.

Im currently running AOSB on 2 devices. When I first flashed them, I had the same issue until I rebooted the phone. After that I never had this issue again.

I think that's the opposite of what happened to me. My status bar said I had LTE when I first booted AOSB (this was after flashing/wiping TW). After the first reboot it connected to 3G and I haven't seen the LTE signal since.
I have updated the APNs, but I was using the same APNs for a while and had LTE on CM10.2 with them.

This is something wierd with Kitkat. I do not believe a fix has been found just yet. but if you dial *#*#info#*#* on most phones you can get into the phone systems and turn LTE back on.

There are some other options in there for networks (e.g. TD-SCDMA, CDMA auto). Would any of them help picking up Sprint LTE?
Other options include:
Turn off radio, CellInfoListRate
Turn on IMS registration required
Turn on SMS over IMS
Turn on lte ram dump
SMSC:_____________ Update Refresh

KitKat roms are currently having data issues. You could try backing up your current KK rom and go back to Stock, update prl and backup your DNS settings then go back to your backed up KK rom and restore from the dns settings you backed up.

ohhh i had this issue but i figured it out for pacman and most roms just download nova launcher and when you do create a shortcut on nova ad click on setting an it should say apn once there u open it and youll see where it says ehprd something like that click on it and go all the way to the bottom and change where it says bearer to ehrpd and lte should work ^_^

Ok so I finally got it working, although I'm not sure what was wrong with everything in the first place. My buddy said Cyanogenmod screwed up a recent ROM, so maybe that code was in one of the ROMs I was using.
Each time I flashed back to TouchWiz (I ended up using Wicked Sensations) I could get 4G/LTE. I ran a **72786*, did a PRL & profile update. Prior to finding a working ROM, when I went back to BeanStalk/PACMAN I would lose LTE. After I found the updated BeanStalk ROM I flashed and it still had LTE! Happy days!
At this point I was able to send MMS somehow, but phone was having problems being recognized by the network. I could connect to LTE but couldn't use the data. After I updated the APNs everything started working again.

Can't make calls out (Random only on network mode WCDMA/GSM (Auto Connect)

Hi.
I have a Samsung Galaxy S3 T999 model on carrier T-mobile. Lately the phone has gone nuts and will get stuck on dialing out and will never make the call. Everything else works fine. Sometimes I have to soft reset, pull the battery and that will fix it for a call or two, then it will get stuck again. I have contacted T-mobile about this over 5 times and none of them can help. We tried to change the sim, reset the account. Etc and nothing. I have reset the cache, factory reset and even put in a good working sim card from another phone and the same problem comes up. During my latest troubleshooting I have narrowed it down to where I switch "network mode" to GSM only and that can make calls out all the time, but the data stays on E (which then I can't use the internet because it's so slow) When I switch back to auto I am sometimes able to place calls again, but only a few. After I test a few calls and leave the phone for a few minutes the phone will get stuck back on not making calls out and just saying "dialing".
Has anyone had the same problems or know of a fix? Currently I have been trying to flash the modem to different versions to see if that fixes the problem. The first two modems I have flashed did not work and came up with "unknown baseband".
If anyone can help I greatly appreciate it.

This is a known issue with 4.3.. What firmware are you on? Assuming you flashed the correct baseband for your device, the 'unknown baseband' message sounds like you are in 4.3 but what build? You can't flash any modems successfully less than 4.3

I was previously on 4.1.2 when the problem first started. I updated it to 4.3 and still the same problem.
jss15j.t999uvuenc2 build. (I put this one back on last night so at least I can use the phone today when I am at work)
I was just hoping that the device didn't go bad when it was on 4.1.2 because it was working just fine before the problem started.

Was it official update to NC2 by OTA/Odin or you just flashed a ROM?

NC2 was OTA. After doing some searches it said that OTA could of been corrupt, so I went and downloaded KIES and did a reinstall that way.
When I upgraded to 4.3 I tried that default baseband out and had the same problems. That is when I was searching on google and came across this forum and also the thread about flashing modems.

APN is epc.tmobile.com
Network Mode current set to GSM (the only way I can make calls out without the problem occuring)
WCDMA/GSM (Auto Connect) is what it should be on so my data is at 4G, but the calls is the problem here

I am not sure but can you check the settings of the Dialer to see if there is ways to choose Lookup providers ?

Nope don't see anything in the dialer about selecting a provider..

Its supposed to be something about Choose Lookup Providers. At least that's the way it is on AOSP.

I suggest Odin flashing the stock NC2 firmware and then factory resetting from stock recovery. (Backup first of course!) If it is still an issue, it will most likely be a hardware problem. From what you have said so far, I believe that you will find this to be the case. Could've been due to damage from a drop, or even overheating at some point. Or it could just be that its simply due to hardware degradation over time.
