Default [Q] Using triangle away with official 4.3 update

Hello everyone!

I'm about to upgrade my device, will get a S4, but I had previously installed custom roms in the past, and the counter has tripped, right now I have the 4.3 update, do you guys know if it wont brick my device? I only have root access and disabled the knox security, besides that, I'm running with everything stock

Thanks for your help!
