At least that's what I think it was... I rooted, unlocked BL, and flashed a couple custom ROMs and radios on my VZW GS3. I tried JellyWiz, AOKP, ParanoidAndroid. I can't be sure exactly when, but at some point, I lost the ability to get a good signal.
I work in a basement where only Verizon gets service. I used to get 5 bars all the time here and was able to get 1X network coverage and stable WiFi. After rooting, ROMing, whatever, I couldn't get any signal at work (the big circle-slash symbol), was dropping WiFi like crazy, and at my house which is a good 4G area, I could barely get 3G and making a call was a hopeless endeavor. I would constantly drop calls, and the ones I didn't drop were so choppy that the person on the other end of the phone was completely unintelligible.
It should be noted that with each new ROM I flashed was a clean flash. I Odin'd back to stock everything to try to remedy the issue. Bootloader got relocked, baseband reset to stock, everything. I put this phone back to exactly how it was out of the box. The problem persisted.
I finally got a replacement phone and the problem is gone. Besides the fact that my VZW-using colleagues had signal the whole time, this new phone also gets signal.
Now I'm hesitant to tinker with this thing because I'd rather be on stock TW than have a phone that is non-functional at the two places I frequent most - work and home.
Does anyone have an idea what happened here???

I am currently running Ninja-0706, radio 26.06.06.30_M.
Intermittantly, my phone will drop out of H and start cycling through all the connections, edge, gsm, 3G etc. After cycling through, it will go to no connection at all where you see "no service" on the screen. And it will stay like that for several minutes, no matter where I am standing in my apartment, or even if i walk outside. Then all of a sudden, it will pick up H, full bars and it will stay like that.
So far, this issue has only happened a couple of times, within the past couple of weeks, and at my apartment. I have full wiped and flashed different roms, and reflashed the radio after the first time this happened, so this issue cannot be blamed on current said rom. This has led me to suspect that maybe there is an issue with the tower in my area. Twice I have called AT&T now about this issue. Both times they claim there have been no outages or issues with the towers in my area. They also claim that the closest tower to me is about 1 mile away, so there shouldn't be issues as such with a tower so close. I don't know anyone in my complex who is on AT&T to see if they are experiencing the same issue. So AT&T seems to think there might be an issue with the phone and i might need to do a warranty exchange. Any ideas before I flash back to stock and exchange it out?
While mine doesn't go that far, it'll cycle between H and 3G for no apparent reason.
Mine does weird **** sometimes, too, on Tue 04_11_M2 radio.
Just today I was sitting around browsing via WiFi, and bam, no signal. Most if the time it'll kick back in after a sec or two, but it stays like that until I intervene by toggling airplane mode, then, it'll be back to 3-4 bars or whatever.
Second time its happened over the last month, so no biggy.
In my house I get lots of signal variations overall, which I guess should be expected.
Well, my phone has done it twice since OP. I just flashed back to stock and downgraded to s-on. I'm going to see about an insurance claim.
Update: Just got off the phone with AT&T. They said that this issue would need to be handled by the warranty dept. So got back on the phone with tech support and they suggested that I go into an AT&T store and have the sim card replaced before they replace the phone, as the sim card itself might be causing this issue. It seems plausible because the sim card is needed for a connection to the network.
Almost every rom I flash ends up having the same problem: I randomly lose signal. Not the crossed out icon, but rather just no bars. This happens while sitting still and there does not seem to be any pattern to it. Some roms it would happen overnight, others it happens during the day. Some roms I can toggle airplane mode on and off to fix it, while others I need to reboot. I always end up back on stock roms because the issue renders all custom roms unusable. Does anyone know what I can do?

Have you tried going stock and see if the issue arise?
Did you try to go 2G only and see if your signal holds?
It could be a bad 3G signal and your phone is dropping in/out to boost your signal. you could be between two towers and your phone jumps from one to another because of low signal. Could be a bad antenna if the problem persist under stock and 2G only. There are alot of things that can cause this issue and the phone itself can be the source. You have to factor out every possibility to narrow it down.

I'm switching to 2g only and we'll see if it holds. I'll know in a few hours.
I would be surprised if it has to do with towers, it isn't something that happens exclusively in low signal areas.
At work I have full HSUPA+ signal and it still happens, at home I barely get 3g signal and it happens there.
It happens at my girlfriend's house too and there is moderate to high HSUPA+ signal.
The problem DOES NOT persist with stock roms.
DOES NOT lose signal when data is disabled
******************UPDATE***************
even when locked to 2g only, it still loses signal.
Seems to be a hardware issue. I had the same problem on my last phone (a LG-VU) and I red-necked it and stuck a small piece of wire in the phone's antenna. It worked surprisingly and I had no problems with it for the remainer of my contract. But before going to those extremes, I would flash back to stock gingerbread, and try several different ROMs and Modems.

HAve you tried falshing different modems???????
You might have a bad sim card. My phone was doing that last summer, and then one day I couldn't get a signal at all. Rebooting would fix it but only momentarily. I hit up an AT&T store on my lunch the next day and got my sim card swapped and lo and behold, no more problems. LOL I remember I was trying to hide my Cognition boot screen from the tech as my phone was still under warrenty at the time.
I got my vzw gs3 on Oct 1. Within the same day I had it wiped and put on AOKP jelly bean rom. Essentially since i've had the device, i continue to have issues where the phone drops data completely. This isn't an issue of cycling between 4G/3G, as even if I disable LTE, I still have problems where 3G drops and I have no data at all, after about 30 seconds, data comes back.
I came from an vzw OG Droid 1, and still living in the same house, I never had any data issues like this on that ancient phone. So I'm confident it's not the area I'm in the or the towers, and has to be a hardware or software issue.
Has anyone else experienced complete data drops on the S3? Is there any solution?
I've searched around and it seems I'm not the only one. For example, https://community.verizonwireless.com/thread/777654.
I've tried a battery pull, pull out the SIM card, turn the phone on, do another battery pull, put the SIM back in, and turn it on.
I've also tried flashing different modems, from here http://rootzwiki.com/topic/34053-of...zon-sgs3-sch-i535-odin-or-recovery-flashable/, to no avail. The problem never got better, only worse.
I535VRLF2 - Original modem that came with the device
I535VRLHE - Didn't help
I535VRLI5 - Didn't help
I535VRLJ1 - Made it worse
I535VRLK1 - Latest modem leak, going to try now.
The last resort option I'm going to try is flash back to complete stock and see if I still get issues.

I live in a place where 4G is rough and work in a place where no 4G and 3G was rough.
J1 seemed OK at first, once it settled it got bad, flashed K1 and seems to be holding strong, will have to try over a few days and see.

Hey guys I just started having problems with my OPO, I'm rooted and bootloader unlocked on 38R, Had the phone for about a month now and bam today a couple hours ago my signal ramps up to full would stay there for a few seconds and then drop to nothing, same for data, it would get a H+ signal and then by the time I go to check a website bam, back to no service. This just started happening today, I did nothing different with the phone at all. I did read around and I see people with somewhat similar problems to me but not quite. They seem to get problems doing a OTA or flashing roms which I haven't done yet.
I haven't dropped the phone or anything, this is really weird cause the phone actually got better reception of all the phones I owned previously. As I said, randomly started doing this today. Any help or suggestions would be appreciated.
After flashing CM12 on my nexus 5 (D821). I flashed the 20 jan Nightly and everything was working fine untill i update to the 22nd jan nightly when my 3g simply stopped connecting or had very spotty signal, i didn't give it much thought at first thinking it was a nightly problem but after one week i reflashed stock lollipop, locked the bootloader, even tried kit-kat and the problem is still there. Before flashing cm 12 2g/3g/lte switching was working perfectly for about one year.
So utill now: i flashed different stock rom's, different kernels, radios, custom roms and nothing worked. When i tried switching the sim with another one from the same network, 3g worked on the other phone so i doubt that the sim is defective, but on my nexus i had the same connectivity issues. I also played with the *#*#4636#*#* menu and managed to get 4G working again but only in CDMA mode and I cannot receive any calls or texts, but the internet connection is working, 3G also connected at some point but the signal was very poor.
I am lost now, and also desperate because edge is too slow for anything. What confuses me though is that this seems to be a software issue since the cause was me flashing a different ROM but all the signs point to a hardware issue.
Can anyone plese give me a second opinion? Is there any fix for this? (Also i recently went to my network's service to replace my screen assembly, could also this be an issue? the issue appeared about 2 days after getting it back from them, also about the same time i flashed cm12)
Thank you for your time.
Also another thing i just noticed:
I opened my phone's back cover and the writing on the frame covering the motherboard says D820 and in the bootloader my phone shows as D821. Is this common for every D821 model?
I started to wonder if i got all my components back from the phone service... Although it's highly unlikely that they mingled with the motherboard since everything that i had on my phone was still there (custom ROM and all my personal info) maybe they switched the antennas...
Is the antenna connected?
Im going with disconnected antenna as well.
