So I was on 2.2, rooted using the method on xda. Everything went swimmingly. I'm now on rooted stock 2.2 rom. Wireless tether doesn't work, which I assume is because I need to flash a custom kernel. I also can't seem to flash a custom rom, which I think is because I'm not nand unlocked. I used unrevoked forever and am s-off. I used amon ra recovery I guess. But I also installed whatever with rom manager. So I'm wondering, how do I nand unlock? Is it just a full wipe including the dalvik cache? Do I always have to do a full wipe when I flash a rom? Is there a quick and easy way to nand unlock? It looked like I could full wipe with the dalvik cache from recovery. What's a dalvik cache anyway? And about flashing roms, am I going to have to flash antennas and stuff every time? Are all roms pretty much compatible with all the custom kernels? Or should I check and make sure to check all the compatibility for that stuff? Is there a kernel that will both make my wireless tether work and break the 30 fps cap? And what about improved performance and battery life? So many questions!
