Root [International] Wifi not working, Can I downgrade?

[xSaxby]

I rooted my Samsung Galaxy S3 yesterday on 4.1.1 and then I removed the root and it was fine.

Today, I updated my phone to 4.1.2 via kies and when I tried to connect to Wifi it wouldn't work and I get "Authentication Error Occurred"

Could I download 4.1.1 and put it onto my device via Odin?

I'm new to this, please help.

Thanks.

Welcome to the forum xSaxby.

I'm guessing it will be the wifi settings from your old firmware interfering with the new. The first thing I'd try would be forgetting the connection and then reconnecting. If that fails I'd factory reset the phone. If you don't already have all your apps backed up from your previous root, root again and back them up first. Then only restore user apps and data after the reset.

Thanks for your reply!

I've done all of this and it's still happening..

Could I downgrade with Odin back to 4.1.1?

I don't want the phone to be rooted..

Thanks.

Yeah you can downgrade with Odin. You can get your firmware from here, just fill in the drop down boxes.

Out of curiosity why don't you want to be rooted?

I'd rather have my phone go wrong on it's own accord, not due to it being rooted.

And I personally would rather not have to go through the hassle again, As I'm new to Samsung.

Thanks for your help. I've sorted the issue now.
