I just gained root privileges on my stock 2.1 this afternoon. Now, I'm looking to forward to installing BB v.4 and then figuring out what kernels my droid can handle. I've read all sorts of things in these forums, but I'm basically a n00b, so I have two main multi-questions: First question: what is the easiest way to install BB? The posted link seems to be in the update.zip format that I used in SPRecovery to get root access earlier today. So can I just rename it update.zip, put it in /sdcard, and install? But I'm coming from 2.1, so do I need to wipe data and cache? How? Do I need to do this 3x? I know that some people use Rom Manager and ClockworkMod Recovery. Is this a different process altogether? Second question: what is the best way to test kernels? Chevyno1's kernels are very well reviewed, so I'm looking forward to playing around with them. I know that different hardware is different, so if I experience errors, I need higher voltage or lower CPU speed. But what is a boot loop, and how do I avoid it? What battery temperatures should I look out for? Can I use SetCPU on BB, or does Pete's script render it useless? Thanks for all the help! It's been really fun so far.
