[Q] Problems with Skyrocket disconnecting when turned on

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.

Tinji GT-i9300 signal/service freezes

Hi all,
I have recently purchased a Tinji GT-i9300 4.7" S3 clone phone with Android 4.1.1 and Kernel 3.0.13
It all works fine apart from the signal/service freezes all the time. The signal will freeze with-say showing 4 bars even though I'm now in a no-signal area, I could even put it in a lead box and the signal indicator would still be stuck on 4 bars. When it freezes, I loose all service, even if I'm in a strong signal area. It might be something to do with when it's been sleeping for a while. I can get the service back by selecting Airplane mode and then unselecting it.
I've tried different SIMs from different providers, but they all act the same.
I've tried the obvious, like reset to factory. And I've google'd for ages, trying to find an answer.
Does anyone have any ideas or a later firmware that I can try? or do I send the phone back to China?
Thanks for looking.

Just some extra information
Just some extra information:
I have stopped the phone from going to sleep and have adjusted the CPU (I had to root the phone) to not drop down low, and it's not lost the service for hours. I will experiment more to find out if it's the sleeping or the CPU speed dropping that is causing this problem.
I believe this is quite a common issue on many android phones.

I FIXED THIS PROMBLEM!!!!!
This probably isn't going to be the answer for most of you but it worked for me. I tried all of the suggested fixes first and had tried 3 different SIMs and my phone still had the radio service freeze.
Yesterday I went into the EE (Orange) shop and got a brand-new SIM and now my phone works perfect and even the signal strength is a lot better.
Try getting a new SIM, it MIGHT FIX your problems. GL

Cannot make or receive calls(Emergency calls only)

Hi,
From past three days, signal is not showing up on the phone. And it only shows a red triangle with a white plus sign on it.(Emergency Calls Only)
I didnt do any changes to the phone, it just randomly started three days ago.
I am on Indian version of unlocked Motorola atrix 2 MB865.
I am on jellybean 4.1.2 for past many months. So I dont suspect the ROM.
I have tried using some other sims also.(It is NOT the problem of the Sim)
I usually get full signal at my place.
I have searched internet thoroughly and read almost all the threads related to this topic, but it didnt help me much.
Things I have tried till now.-->
- Swapped sims with many other phones.
- Installed the "Network" app and many other similar apps which was suggested in some other threads.
- Switched Flight mode on and off.
- Factory reset the phone.
- Kept it off for hours and then checked again.
- Prayed that it will get fixed soon
Q) Did you try turning it off and on again?
Ans) Yes..yes.. Many many times. Sometimes, after reboot it shows signal for 2-5 minutes, but I CANT make/receive any calls/sms(The call just drops two seconds after dialling)
PS:- I think that when I received the last call, I was listening music on my headset and I had received the call with the headset.
Thank You very much.

Is the Baseband version shown, or is it blank?

Baseband version is showing as 2012-0712 09:44 Off Blf LUD_EDISON_R1E_PATCH_36_120712_0920 ch1090280_M570_PC_CARD_RAINB

I have now found that it is due to very very poor reception.... For some reason, this phone's signal reception has drastically reduced.
I can get signal only if I go out, still the signal strength is shown at maximum -75dB and frequently dropping to -100dB. I was able to make one call and it dropped as soon as i entered inside the house.
(The same sim on other phones have full range even inside house)
What is the suggested solution?
Thanks

Seems to be a hardware issue then. Is your phone within warranty, by chance?

Nop it is not in warranty.

If you can't afford to help, then what's the point of this post?
Increasing post count I guess.

Might be a loose connection after a drop ?
Your best bet would be to dissamble the phone and assemble again. In the meantime check the connectors and others if they're in their place. There're good disassembly videos for atrix 2 in youtube.

K s h i t i j s, who is your network provider? EDIT: Just saw that you're on MTNL.
I have been having a similar problem for a similar length of time with my Atrix 2 and I'm on stock ICS. I got my sim replaced by Vodafone but the problem persisted so I asked the guy who originally sold it to me to get it checked out (warranty is long gone).
He mentioned that another customer of his with the same phone also developed the same problem around November or December 2013. Both that guy and I are on Vodafone, Mumbai.
In testing, his phone worked perfectly with an Airtel sim and mine worked perfectly with a borrowed IDEA sim. Both our sims work perfectly in other phones. Both were then sent to the official service centre but they essentially threw their hands up.
The coincidental timing of the problem for two (maybe three) phones of the same model leads one to think there must something with the network broadcasting? Could someone with better knowledge of the subject (mine is approximately nil) comment?

[Q] Weird behaviour on 3G or LTE

Hello,
I'm asking for some help to diagnose my call problems on UMTS.
First of all, three things happened recently, and let's assume that they happened roughly at the same time:
I dropped my Nexus 5 on concrete shattering the screen completely;
Google released Lollipop which some people believe has problems with 3G and LTE;
I'm using a rather old SIM card manually cut to fit micro-SIM dimensions.
About two days after receiving my Nexus 5 back from guys servicing it (new LCD screen) I had a telephone conversation that was disconnecting once every minute or two. There was no problem recalling though. The same day later I noticed that dialer app says "Emergency calls only" which was pretty weird. I was on Cyanogenmod 11, some recent nightly back then.
My first guess - revert to earlier nightly via TWRP. It didn't help - I was still on emergency calls only and nobody was able to call me. However, I could browse Internet without any problems on 3G.
Second guess - clean flash stock 5.0.1. It didn't help too, however calling went back on for some time (several minutes) before breaking back to "Emergency calls only".
Third guess - buy a starter SIM and check if it works. It did at first but stopped after an hour or so.
Fourth guess - bring the phone back to guys servicing the LCD to check antennas. I've left it for two days. It was opened and antennas checked. Everything was fine, not even a bent flex.
For all this time when on 3G/LTE data transmission worked flawlessly. I could download Google Maps, browse the Internet, whatever. It's just the very basic phone function that acts weird - as if I wasn't registered to a network. Everything seems to work fine on 2G, except for very rare disconnects (once per two, or three days).
So, considering it's pretty weird I'm seeking for help - could it be possible that after hitting concrete something broke down on the motherboard that results in such weird behavior? Or is, perhaps, my retro-SIM dying? Any ideas? Maybe flashing a well-tested radio ROM? Diagnostic apps?

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.
