Consistent Network Signal Drops on AT&T - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

I have been having this problem is I flashed GalaxyMod RLS16 about a day ago. My phone seems to lose signal completely about every five minutes. Ten to twenty seconds later it turns back on. I have formatted my extsd card and internal card. I've re flashed to AOKP and have tried two different modems, same result. Called AT&T, they re provisioned. And it was fine for about 20 minutes and the the problem arose again and is still occurring. Any sort of tips?

Easy answer is that those Verizon based ports are not completely stable and reliable on our devices. There are APN, modem, and other issues that cause them to loose connection because for some reason they haven't been able to optimize them form our devices and there are some amazing devs working on those.
If you want reliable stick something that is at&t, tmo, or Canadian based.

Well yeah. So I flashed back to Tasks AOKP, but the problem is persisting.

Flashing ports like that can create some issues that only flash back to complete stock rom , formatting everything, and reflashing my rom (or whatever rom you choose) will fix.

Don't mean to be a burden. But, i have the stock rooted flash files for Odin on my desktop. I'd just flash those correct? And before I do something to mess anything up, I'd just flash it over your ROM right now correct? Don't need to wipe or prepare anything else right?

Same procedures used as when changing any rom. Wipe data/cache/dalvik then flash

Yes just flash back to stock using Odin. I wish some of those Verizon ROM's being ported over said WIP just so people know it still is. I've never seen so many requests for how to inject their IMEI.
No need to prepare anything else. Jusy flash stock rooted 4.1.1 and then Task's AOKP. Not my cup of tea but the heck if that man doesn't put a lot of work into that for it to be great.

My IMEI was intact the whole time. I just flashed a AT&T touch wiz ROM. (Intergalactic to be exact) and have had no problems so far..weird. Wonder what would happen if I tried an AOSP based ROM again.

It's safe to assume you will be fine. I just think it was the Galaxy ROM you flashed and interglactic is a good stable ROM. Make a nandroid and flash an AOSP one.... got nothing to lose if you back everything up.

Same thing happened to me today. Maybe it wasn't a mistake. Is it your ROM Jellybam 5.2.0 by any chance?
After odin'ing a stock rom, if still no service, another important thing to check is under "about phone" under settings. Check baseband.
Also look in "about phone" under "status". Bring a screen shot. Lots of blank fields is a bad thing...

Indeed, flashing a stock rom through odin did it.
I tried every other solution (ktool, moving files using root explorer and terminal emulator etc.) with no luck.

I'm having trouble with getting data to work with the ROM when I flash. Am I missing something?

Probably not... sounds like a bad download... redownload to pc and do a full wipe and reflash. Now hopefully you haven't switched prl's and you have updated to either MA6 or MB1 because they are basically the same and this rom will run on both... let me know how it gows...:good:
4g not working

I re-downloaded and flashed and it finally started working the thing i noticed is that the 4g is not working it wont connect but when i put only CDMA on 3g works fine but once put on lte settings no data at all and i am in a good 4g area could it be a bad download still?
Nice to see a ROM discussion thread hosted by the dev...good work V!

Is it possuble or would you mind to pull the dialer and status bar tweaks out into flashable.. I would like to add them to the stock deodex setup I'm currently running.

Ok so from my reading I see that its cool just to full wipe then flash this rom right over LJ7 right? Then after that I can update my modem to MA6?

Yes you can do that. I would just update to MB1 modem though (MA6 and MB1 are basically the same but you will still get the update notification on some roms if you don't do the MB1 modem update)...
Can someone on v2 try going into settings/network where you change lte on and off and see if you get fc. It says com.android.phone has stopped working. It worked on v1 and I did a clean install from v1 to v2. Thanks
Running a Rom by someone smarter than eye.
I changed mine to cdma/lte no problems at all.

Awesome looking. Gonna test this bad ass ROM. I'll report back if i get any issues.
Just flashed today and so far so good. Only thing I have noticed is that it reboot twice in like the first hour but nothing since then. Also wish I could find how to change the lock screen in the atom launcher settings.
This Rom is straight up solid.

Yeah I checked but this device is weird as you know and I wanted a bit of assistance not wise ass remarks. I'm new on this part of xda and with a flashed phone I know some roms don't work correctly. That's why I asked not to be lazy. Check my stats I do a lot of support for the one xl. And one thing I wouldn't do was post a link to a totally different device, someone with less common sense could brick with wrong info.

My bad, I read that as G2, I apologize. I was confused as to why this was posted here. If you want a ROM that works correctly go with TouchWiz. AOSP ROMs are pretty buggy on this device, especially KitKat.
What do I need to do to go from stock rooted this is a confusing device and I also still have stock recovery
Gb27 by the way

Get Mobile Odin, flash this kernel (.tar format)-http://forum.xda-developers.com/showthread.php?t=2244781 in Mobile Odin and that will give you a custom recovery
Would u recommend wiping dalvik and cache? Or is it safe to just reboot into the stock rom?

If all you flash it the kernel, its safe to reboot without wiping anything. However, I would follow any and all directions given by the OP of any ROM or kernel you flash to the letter. Otherwise, you're asking for issues. This is a confusing device, and there are so many little nuances that need to be done just right to avoid problems.
If you take nothing else away from this post, remember this website www.rwilco12.com, it will save your device if you run into issues or just need anything for the device. Every ROM, kernel and modem leaked and/or released for this device by Samsung is on there and will return you to stock in a heartbeat.:good:

Speakerphone problems..

OK, I have notifications and music playing through external speaker as normal, but when I try to use speakerphone it goes silent. The earpiece works fine in calls, but speakerphone does nothing. I am rooted and this problem persists across all of my backups (carbon 4.2/pac 4.2/Mokee 4.4/stock ics 4.0.4/Slimbean 7 4.2) the only audio mod I have used was Viper4android and Sony Walkman, and after every restored backup no speakerphone, I have also tried flashing new roms (Cm9) just to test and it still persists. I am running FK19 and the prl is 15110 (flashed custom prl). could this be a hardware issue? even tho the other sounds still play through the external speaker?
Thanks
It's been an issue with AOSP-based ROMs for quite awhile. There's no fix.
Try flashing the latest GB27 ROM.
Sent from my SPH-D710 using Tapatalk
Bummer, it even occurs when I flash or Odin stock ROMs though. I can't use the gb27 ROMs yet as I haven't been able to successfully convert them to uscc yet. I got an unbranded (no carrier) gb28 but MMS is still an issue.

GB27 and GB28 are essentially the same thing... Did you change your mmsc url and apn?

Yep, used gesture search to open apns and think it was ##data#? That opened the other settings menu, but mms didn't work.
Maybe I missed something somewhere. I have the odin flashable gb28, used the cwm installer bat file, and flashed the agat recovery. after that I got bootlooped, and the factory reset/wipe didn't fix it. Maybe I could use the TWRP recovery instead? I did spend a lot of time trying to get the Touched by an S4 rom to work, but I still got bootloops with that one as well. I used the jb format all x2 zip before install, but I was thinking that maybe I flashed it from the wrong recovery. Im gonna go re-read the op instructions again and maybe take another swing at it. Any suggestions would be welcome, along with hints, tips, clues, and up to and even including "hey dumbass you forgot to ......"
thanx

Successfully odin'd gb28 and then odin'd agat. also was able to modify ACPverter (uscc zip mod) to change build prop and eri.xml in framework-res, still no luck on getting the apn settings to stick (MNC MCC wont take, dont know the correct values and the old ones wont work), also ##3282# , and ##72786# won't work and I am unable to change the MMSC url.
All that being said it is still running very well and thanks again for the advice on odin'ing everything. if only I could odin tbs4, anyway its a good starting point and stable enough for me to mess around with even though the speakerphone still refuses to work....
ok so I did some reseach and found that the speakerphone issue is from the sprint kernels, around cm10.1 they start to break the Bluetooth and speakerphone, prior builds have success in some cases. time to odin the hell out of it and see if I cant get it back! I have about 4 different tar files for ICS and Gingerbread, and I am gonna give them all a shot
Note: while odining the gingerbread build, after reboot it showed "decrypting meta data" and some other things I couldn't read it fast enough....weird.....
ok stock ics, stock rooted ics, stock gingerbread, stock unbranded JB, stock pit files with ics and gingerbread = no bueno speakerphone/Bluetooth!!!!! anyone got any other suggestions?
Update. I also changed the speaker/antenna that is mounted inside the housing at the bottom of the phone. I replaced it with one from a sprint branded phone and still no luck... S3 arrives next week..

So I received an update from T-Mobile which said it had stability improvements. But then I also noticed they updated the baseband. I can't see or feel any noticeable changes. Just putting it out there in case you haven't gotten anything yet if you're on stock. I was hyped for something else

More than likely because of this http://www.computerworld.com/s/arti...s_to_some_Samsung_Galaxy_devices?pageNumber=1
This indeed is the most recent update Rolled out by Samsung. It very well could be related to the flaw discovered. It is also likely meant to answer the signal issues some users have experienced with the last update. I have posted a little guide to Root this version.
Would it be possible to get a modem pulled from the new update?
