Rom toolbox pro stops working for me every time I select rom management or go to the settings at the top right corner in rom installer. Im new to all of this and ive spent days trying to figure it out. -galaxy s3 T999, rooted, nova launcher saved my ass.

Also, can someone please help guide me through making a nandroid backup in Rom Toolbox pro :(

And what do you guys think of CyanogenMod 13 Android 6.0.1 Marshmallow ROM?
