I have a number of problems which started after I rooted my S3.

1. I receive a notification that an Android update is available. I downloaded the update and hit 'install', after the S3 reboots I get an 'update failed' message.
I then download a temporary disable root app and try again. Same deal.
Fine; I can live without the Android update, but I can't get rid of the top-of-screen update notification symbol & I get a pop-up every 3 hours asking to install. How do I remove the symbol and update reminders. I guess I need to start with removing the downloaded update file, wherever it may be located?

3. Speaking of notifications...I can't remove the Samsung account symbol either. It's there because I foolishly decided to sync my contacts located over various social media accounts + email, Skype & my Samsung account. Needless to say my phone contacts are now a complete mess. So I turned off all account syncs, but I still can't get rid of the sync failed notification for my Samsung account.

4. I want to do a complete backup of my S3, a bit like what iTunes offers for iPhones. So I installed Kies on my Windows 7 (64 bit) pc. I plugged my S3 in to the PC via USB and I get the notification the device drivers won't install. Which is a pity because I can only do a complete backup via USB. So I went and tried installing the latest Samsung mobile drivers. No joy. still get same installation fail message.

 

Thanks for that. When do you hold down all the buttons to go into recovery mode? I tried holding tohem all in after restart but nothing seemed to happen.

 

Thanks. I'm a bit confused about the custom rom bit. I rooted my phone so I could apply a volume hack. Does that mean I've got a custom rom applied? If so, are there updates released for custom roms and how would I apply them?
