[Verizon Samsung Galaxy S III] mkruluts:
Just in case this post gets moved, I want to identify my device as the Verizon Samsung Galaxy S3 (i535).

To give a little background on my issue, I have an issue with the device. When I first got it back in July, first thing I did was root the device. Naturally, since it was a new device, I was working with experimental methods... a couple weeks ago I thought to download CyanogenMod 10.1 (nightly build) to flash it with 4.2 and rid myself of the persistent OTA update that as we all know could not effectively install because of the measures I took to root. So, I boot into recovery and flash my custom rom. BAM! As it turns out, I did not have an unlocked bootloader and my phone was now teetering on the verge of being a $600 paperweight. I got that dumb yellow triangle saying unofficial firmware detected or some nonsense like that... Anyway, I look around the internet and decided that I was going to revert back to a stock rom using Odin, and then proceed to unlock my bootloader and root the device (I followed method 3 here) I used some touch recovery console that I have never heard of before (backups incompatible with ClockworkMod recovery) and something must have failed because my back up would not flash. I took the hit on losing most everything and reflashed successfully the custom rom mentioned earlier.

After about a week, I noticed the device began to drop data. 4G would just stop at random parts of the day, and I would have to disable and enable the data to get it to reconnect. At this point I was still able to make and receive phone calls and texts. After about 3 days of this, I concluded it was more than likely a bug in the custom rom, and that I could not live with it... so I redid the a fore mentioned tutorial and left the phone as a stock/unlocked/rooted device. The data issue continued, but with a twist. I was now unable to make or receive phone calls or texts. No matter what I did, I could not do anything and the 4G would only stay connected for a matter 5 minutes or so. When I logged into my vzw account, it identified my device as an unknown non-verizon device. Customer service walked me through various soft/hard reset techniques and nothing worked. They also suggested I try a new SIM card, which failed to work.

So, I turn to the bright minds of the android community. I have already decided not to invoke the Verizon warranty offered, where the result is they take my malfunctioning phone in flawless cosmetic condition and replace it with a "like-new" phone in working condition, because I think it's garbage that a warranty would give out used crap (should fix or replace). I have not contacted Samsung customer support yet because I wanted to see what my options were. I've already attempted flashing different radios and nothing seem to make any difference. If I have to, I will revert it back to stock again and invoke Samsung's warranty program, but I would much rather keep the phone. As it sits, I am stuck with my Motorola Droid Razr Maxx, and that just doesn't cut it.

So I ask, is there anything that can be done? Anyone know of a fix for my situation? I saw something about this in my quest for an answer and I don't know if my situation is a fit for this fix. If anyone has any knowledge of my issue and a work around for it, it would be greatly appreciated. I am at my whits end.
