Galaxy S3 I9300 Problems

Hey guys,

I'm from India and I bought the AT&T version, unlocked I think. The build number on the device is JSS15J.I9300ZSENA1. It runs on Android 4.3 Jellybean and is the Pebble Blue version.

I'm using Reliance carrier on it and having frequent call drops, connectivity issues and texting problems as well. Then I get this security notice which asks me to boot the device repeatedly and I don't have any clue why that happens.

Now, my main problem is that I can't use the device for calling purposes as well texting.

So, how can I fix this? When I tried to update the firmware, I found the At&t text on it. That made me think that this might be the right place to post. Anyway, will changing the ROM to a Custom one like Cyanogen help to fix this issue? I need some help with this as I spent some decent bucks on it.

Galaxy S3 gt I9300 Straight Talk bricked

Hello and thanks for looking at my post, I have a straight talk galaxy s3 with a 8gb sd card from straight-talk wireless, I tried to install cyanogenmod (latest) using CWM with the firmware on my phone downgraded to H1 (so I could have root). After this happened, I tried letting the phone charge and seeing what was wrong, I found out 2 things
1) The phone will NOT boot into recovery or anything else, even with a jig
2) The computer makes a sound when I plug the phone in, but I cannot access any of the files
3) Phone is not recognized by ADB
The only light I get from my phone is a solid red light when that only happens when I take the battery out and plug in the phone with a USB(The light is a solid RED)
I do have a read/write tool for micro sd to computer, but I do not know if it would help me, I am at wits end and am very frustrated at this sudden brick, please help if you can.
Any and all help you can give me is well appreciated, thank you in advance, if you need any other information please don't hesitate to PM me or reply.

How to solve "PIT Partition Error" for S III I9300, Please Help !

Hello,
I was running on a stock non-rooted ROM, when the phone did not suddenly did not boot any more. Instead I am getting a "White Screen with some black lines" not even the Samsung Logo screen. I tried to acess the recovery mode, but this seems not possible. I can only access the download mode.
When I tried to flash a new stock firmware through odin, I got the error message: "There is no PIT Partition". Same happen when I tried to flash the firmware with three/four-parts.
I look through multiple threads and tried to apply the methods given in
1) http://forum.xda-developers.com/gala...em-gt-t2535367
2) http://www.android-hilfe.de/thema/i9...teilig.517665/
but non work so far, and I am always gettein either "Re-Partition operation failed", or sometime ODIN just stuck on "SetupConnection" and never go further.
Since this is a 2+ years old device, Service Center is not an option for me.
Can anyone suggest me a method to solve this error. Maybe provide me with new "PIT Partition" file, etc...
Thanks in advance.

UK Galaxy S3 i9300 on 4.3 rooted (today) none of the unlock methods seem to work

Hi all,
I'm a noob.
I've swapped screens and rooted several phones but only under your instruction. I have no skills.
I rooted my old S3 today (now living in Spain) but cannot find a solution to unlock it from Orange/ EE (UK)
If I have to pay, I have to pay, but I like reading and finding how you guys solve the problems and then trying it out so I joined up and now I'm reaching out for help.

Thanks in advance
