Please bear with me...this is probably a dumb question. The NAND backup has 3 options. 1. Device recovery. 2. Rom manager 3. Amon_RA. I'm a bit confused. I choose one of these options?? Which one is the best option for a very nervous rooter?? Rom manager has a warning that I will permanently lose the stock recovery....isnt this bad? lol. I just wonder which option I should use. I intend to follow the instructions perfectly from rooting for dummies. One more question, can I just remove the sd card from my phone before rooting instead of formatting it? Does it need to be in the phone for rooting process? Why does my stomach feel so nervous?? Lol Thanks so much for the advice and help.
