Ok, so I got my phone rooted that was easy. I also found a ROM that I want to flash it to. When I downloaded the ROM and extracted the zip file it has 3 things inside of it....META-INF (folder), System (folder), and Boot.img. If I boot into the recovery manager and go to Restore to that folder, it gives me md5 mismatch error. I tried installed the zip file from sd card option and it unpacked and installed it but then my phone got stuck in a boot loop. I noticed that the backup of the stock droid ROM that I did had a lot more .img files in it than the downloaded custom rom i had. I was able to restore my phone out of the boot loop using the stock backup I created.
Do custom ROM's need all those other .img files for them to work or am I missing steps here? I've tried to watch the tutorials and other threads but they leave this part out. All they say is to boot into recovery mode, and go to restore and select the ROM from the Nandroid folders (or clockworkmod\backup\<ROM> in this case.
Thanks in advance for the help.
