My 2nd ACER A500 arrived yesterday for my son and I want to install new ROM. I have some questions and I hope someone can help me on this... I want to preserve my current stock; backup in case I want to restore it to it's original factory settings (like it came out from box) if in any case something's happen. I can use the following: (you may add if in case I miss something) 1. Iconia Root program 2. ACER CWM Recovery 3. Busybox Installer - optional or needed? 4. ROM Manager (v220.127.116.11) - do I need this? 5. Superuser utility fixer - in case there's a problem Now, here's the question: How can I make a backup copy of the stock to my SDCard so I can use it to restore back to my tablet? What is the step-by-step procedure to be able to obtain it's original copy of the stock and make it as a backup for system restoration purposes? Advanced Thanks to all who will reply.
