[Q] Problems with Skyrocket disconnecting when turned on - AT&T Samsung Galaxy S II Skyrocket SGH-I727

I recently bought a new Skyrocket and after I installed an ICS leak and rooted it I lose 4G and MMS not long after I turn on the phone, and have to restart several times until I get lucky and it may work for about an hour or two.
So far going back to stock GB or even the official AT&T ICS hasn't fixed it. I read about the efs folder being corrupted but it still shows the correct IMEI so I doubt that that is the issue. My SIM card also works in my other phone and other SIM cards work in the Skyrocket. Right now instead of thirty reboots with no luck I can stay connected for about a half-hour until I need to reboot again. I am aware that other people have had similar issues but I see no definite solution that applies to my symptoms.
Also, I have noticed that if I disable data and reboot MMS will work fine until I try to use data again and then I'll get nothing.

The problem seems to have automagically fixed itself not long after I posted. I'm still curious as to how it happened or if it happened to anyone else just in case it happens again.

Perhaps I spoke too song. The phone worked fine until this afternoon. An additional thing I noticed however was that while listening to music the audio stops at the same time that the signal disappears. Perhaps the fault lies in the kernel?

I read into changing the APN from PTA. That didn't work either.
There has to be someone with the same problem.

Poll: Phone Issues Poll Data Dropouts and 1-Way Audio calls

I am having issues and wanted to see if anyone else has this problem. Verizon already sent me a new phone and I already have the same problem with it. They told me they will take up to 15 days to investigate the issue. I think its a software or possibly hardware issue, not a network issue.
I get data dropouts - NO 1X, 3G or 4G! Cant use GPS and any apps requiring data connection. It happens every so often and sometimes have to restart my phone.
1-Way audio calls - Person calls me or I call them, I can hear them talking but they can't hear me
Who else is having any of these issues, please choose a poll option from above and leave a comment if you wish.
I voted Rooted, Stock ROM no problems, but when I was Stock I also had no problems.
I am rooted with stock ROM and get the same dropouts as you. Restarting my phone seems to fix it and if that doesnt then pulling the battery out while the phone on does. Annoying that I have to do that but at least I get my data back.
I'm not rooted yet. I have experienced a few data drops. Toggling airplane mode works to get data back. Once, however, I toggled airplane, and the phone couldn't seem to disable the radio. Did a reboot to fix that.
I'm having data drops quite frequently and its becoming pretty annoying
I'm rooted with stock Rom I hope Verizon might be able to help
Stock, with data drops, but not how you describe. I voted before I read your post. My data problem is no 3G. I haven't been in a 4G area yet and if I'm not on wifi, there is no data connection.
Kjjb I'm also having the no 3g problem as well I started a thread about but I haven't gotten a response yet
Rooted, custom ROM and have occasional data drops. Annoying.

Couple of different temporary fixes described there.
I am going crazy here. All day yesterday constant drops in all data types. No bad phone calls, but only talked with a few people yesterday. Today my data drops continue non stop. Has happened 3-4 times already.
I am going to call VZW and *****. They said it would take up to 2 weeks to diagnose my problem. That puts me outside the return window and I already sold my dInc.

[Q] Major Data Issues (Stock)

I have had my phone since it came out, and everything worked fine until yesterday it seems. I had kept the phone stock until July 13th when I flashed the PBJT voodoo enabled kernel. Afterwards everything still appeared to be fine (and much faster by the way) until yesterday, July 17th. I noticed at work that when I turned data on (I usually keep it off to save battery) the phone wouldn't connect to 3G/1X. 4G doesn't really work in my building so I knew that wouldn't work, but I can usually pick up CDMA no issues in there.
I thought maybe it was just a fluke so I kept trying the entire rest of the night to get my phone to connect to any data network to no avail. Wi-fi is the only thing that's useable basically. LTE will connect if I jump-start it via airplane mode, but is then dropped shortly after. I still can't get 3G/1X to work at all though. Even switching the phone to CDMA only it just will not connect. I did flash back to stock EE4 last night thinking that might be the issue (and knowing I will need to be stock if Verizon needs to see it), but that hasn't helped at all.
I'm desperately waiting for a family member to get home so I can get on the phone with Verizon but I thought I might see if anyone here has any suggestions? I've changed about every setting I can think of.

Poor conectivity

I have been having really bad connectivity recently. I have been having issues sending text messages, having slow data speeds, and really flaky reception. And all of these issues in places where I normally have no issues at all, in fact, I dont think I have ever really had issues like this before. Even when the phone says I have signal it still has issues some times. Being outdoors I dont seem to have issues sending text messages, but I still have poor data speeds. However, as soon as I went inside I had almost no reception to absolutely no reception at all. I know some of this could just be related to AT&T towers but my girlfriend is on AT&T too and hasn't had any issues sending messages, she has a "dumb phone" though if that matters. Other things I noticed as far as signal, it would sometimes have data connections shown, but sometimes it wouldn't show anything and under about phone it would say "mobile network is not connected".
I was on 11/4 CM10 when I started having the issues. Tried flashing a couple new MTD modems, checked APN settings, rebooted, wiped cache, airplane mode toggle, but none of that fixed anything. I did a one-click restore back to GB and wiped everything on my phone, internal SD too, then re-downloaded the 11/4 build and reflashed that. Everything seemed to be better for a while but then I noticed that I was having poor data speeds, issues sending messages, and poor signal again. Now I one-clicked back to stock GB again and didn't change anything and only downloaded a couple of apps that I use often to see if it was CM10 that was the issue, but once again I am finding myself with problems sending messages and very poor data speeds. Also, I notice sometimes that wifi connections seems to get dropped during usage and even though it still is connected it gives me errors.
At this point I'm not really sure what I should start looking into. Is is possible that the internal antenna is flaking out or got fried somehow? Or is it possible that it is on AT&T's side? That option seems most unlikely. I haven't dropped my phone or done anything recently that would seem like it would cause my phone to have these issues. Is there a way to test my phone to see if there is something internally messed up? Should I try getting a new sim? Anything else I can do to try and troubleshoot stuff? Any logs or anything you guys need to give me better ideas?
Thanks in advanced!
Edit: Well, in the process now of doing another full return to stock using GTG's method now. See if that makes any difference by the time I get cm10 installed again.
Edit 2: Decided to call the local AT&T store and apparently there had been a couple reports of connection problems but the lady seem a little surprised by how much I seemed to be effected. We'll see if they get that fixed soon and if that fixes my problems. Still having issues with wifi though...
Any ideas anyone? I'm don't know if the att tower is really sucking that much or if it's my phone. Beginning to think it's my phone more and more. Any suggestions please? I can't get an upgrade for another 2 months and this is getting really annoying not being able to use my phone as a phone..

Bumping this thread cause its happening again.
It did seem to be slightly related to the AT&T towers being down because it went away after a day or so after talking to the local store. However, they said the outage lasted only 3 hours and I had issues for a couple of days.
Anyways, yesterday I started having these exact same issues, called AT&T and they said towers seem fine. Asked them about it maybe being my SIM card and they said that 98% likely it wasn't my SIM card. I might go make them replace my SIM card since we pay them obscene amounts of money each month. As far as the phone, it still has Scotts 11/4 CM10 build with the 11/18 kernel patch. Only thing that really changed in the phone physically was I just purchased a 32gb class 10 memory card. The one thing that makes me think it might be my SIM card is there are darker spots in a couple of spots on the gold plating where it looks like it makes the contacts.
Still looking for advice though.
TLDR; super flaky reception, I go indoors in most places and I loose all connectivity. I normally have completely fine coverage everywhere. No issues up until about 3 weeks ago.
I have had ATT for 10 years and have never had good reception indoors. Only reason I am still with them is Verizon is practically a dead zone were I live.
I ran Scott's CM10 and now Liquidsmooth and didn't notice any increase or decrease in signal strength.

The thing is I've been running cm10 of some variety more or less since it's early life and I haven't had issues. It's just on these certain days for certain reasons I have no connectivity in certain places. Most every other days I have no problem getting an H+ data signal and no problem sending or receiving messages in these exact same spots.
I just don't understand these sudden random losses of connection.
Edit: What do you know. Phone is back to normal functioning today. This is wierd...

Signal Dropouts

hey!
I have a problem with my One Mini. I have constant signal dropouts. Phone calls stop after a second, also losing data-connection all the time and always seeing the message "Preparing SIM-card".
It feels like my phone having problems with some mobile-cells. Usually I have to try to call someone 3-4 times, and after 3-4 attempts I can talk normally without getting interrupted after 1-2sec - like my phone found the correct cell or something like this.
I tried
- my second (O2) sim-card
- put some tape on top of the sim-card (solved this problem for people with different phones)
- put some signal-tweaks in my build.prop
- changed network mode (WCDMA/GSM/LTE...)
but nothing helped.
I am on O2-Germany for many years and never had those problems, my One S was working fine (before it got bricked )
Had the same problem last month in France...
anyone else having this problem? could this be kernel-related? I'm using JMZ`s kernel. But I guess this is more a radio-problem, or?

I haven't had this issues, in fact, I went camping last weekend and most of the time I was able to get 1 bar when everyone else didn't have service at all. I'm using the AT&T variant on AT&T with the WWE DeOdexed Stock ROM and Jmz's Kernel 09-04-13. I attached a picture of my kernel, baseband, build, ect. I'd suggest making a backup and restoring your phone to stock to see if it's a software issue.

Simcard isn't detected sometimes

My already 3 years old nexus 5 is working great, except that I have some troubles with my simcard. My phone isn't detacting it sometimes in the middle of the day, without any proper reason and then I have to restart my phone several times to make it work again. I already tried taking out the simcard and putting it back in but it isnt really helping. I also have the problem that my phone isn't really accessing the internet. Even though the 4G symbol is there I don't have a connection, the only thing that helps at these moments is to turn on and off the airplane mode, that way I can access the internet for a quick time, enough to refresh a web page or send some whatsapp messages. I already tried to tape that area where the simcard is placed to make it more stable, without any success.
Does anyone have an idea what to do? I don't really want to buy a new phone since the n5 is working great for me.
Hey,
had exactly the same with my N5. Not sure if it's related to a securtity update or not. I was not able to get it work again. Probably it's getting worse for you with time. There are some threads around xda dealing with this problem, but - at least for me - there no solution yet.
regards
Same problem here since a few weeks.
If you have updated the radio to the last version, and if you have already tried and got the same issue with another sim card, then it may be a motherboard issue.
