Update using a USB drive. Follow the instructions. Don’t worry about bricking your unit, just be patient and give it plenty of time to complete the update.
Bricking only happened with the 1.01.12 firmware last year. Since then, it’s now more likely user error / corrupted downloads.
You could try the 1.03.38 Beta release for additional features (Mediafly, DVD menus) but they should be coming in an official release sometime soon (we hope).
And welcome to the forum!
