Try rebooting the phone at first, if that did not help do a data factory reset. After that if not solved you might reflash a stock rom. Still no remedy, take it to the shop/repair center.

Turn off power saving mode, you don't need to root the s3 it's perfect the way it is.

Am I missing something here? At what point did they even mention rooting the phone? And rooting is still the best way of disabling bandwidth hungry ads in apps.

What type of flickering? This may sound stupid, but it is a legit question. Try making a photo of it.
If it is going downwards in bar-like formation, it's the display.
If it is blinking, it is Android, or a loose connection...

I'm not 100% on this but I don't think default recovery supports adb commands? I may be wrong though.

But what if it doesnt and it bricks my phone? If its confirmed that it will root my phone then I'll try it. I have to be certain. I have been rooting and jailbreaking for years and I know what its like to brick a phone. I eventually got it fixed but it took forever.

i dont think you will mess up your phone when rooting it. if you flash kernel or rom then of course yes but root? no chances. and you said that you can boot your phone to download mode soo you always can flash stock rom.
Did you ever find any info, michaelsinbad?
