OK. First off, let me start by telling you that this S3 is a Canadian sold phone and has the model number I747M.
Now, if your not scared off then I'll tell you what the problem is.
After the update of 4.04 for my phone and the update that went with Kies as well, neither my (S3) phone nor my wife's (S2) phone will not connect to the computer or Kies. I was freaked to find out that this is a big problem here where I live and the cell phone companies (I called many) around here are all perplexed as to what to do. They all have issues as well.
After reading and reading and then some more reading...I'm lost.
As I plug in the phone to my (Windows 7 Home Premium) computer a notification comes up that tells me that "Windows can not identify the device plugged into the SAMSUNG mobile Device. Please contact manufacturer"
Every time I plug the phone in now it installs drivers.
I try but Kies will not connect and all it does is keep searching. Kies Wireless won't either. It just freezes up when I try that.
I have tried the debugging mode, trouble shoot mode through Kies, manually updating drivers, rolling back drivers, uninstalling and/or reinstalling Kies.
After a while a notification pops up on my phone telling me that my issue is with Windows Media Player and I have not installed WMP 11. For any of you who know W7 it comes with WMP 12 and there are no updates for it.
Sometimes, (and this is real weird) I get to see my phone in mass storage mode. Like yesterday, it just appeared when I plugged it in to the computer. I was happy. But then today it just...won't.
So, there you have it. This has been going on for a while now and I am at my wits end. this phone is gsm and has LTE and has all the same gimmicks and tricks yours does. IT is the exact same phone. Just model number difference so please don't say "It's Canadian and you don't have enough experience with that model" because that is malarkey.
I suspect a usb driver issue or a conflict issue with another program.
please, I am desperate. I need some real help here. I need commitment to someone finding a solution. I think its acting a little off so I want to flash my phone, get more music, and other stuff. Please.....please.
