So I'll say sorry ahead of time...im a complete new, paid someone much smarter than me to root my phone. My charge is great but in desperate need of the new update and the others to come. I have no clue how he did it so can someone, anyone tell me/advise me how to download the update with a rooted phone and no clue how it works...if there's stuff i need to download, let me know as i have a Mac. Thanks!!!!
