What exactly is a Backup ROM? - I know it's something which can be used to recover the state of the OS at a later stage but I am looking for a more technical answer, is it equivalent to system.img? I was going through Android Central when I found this article - [HOW-TO] Nandroid Nonsense (BACK UP YOUR PHONE WITHOUT NANDROID!!) I have a HCL ME X1, which cannot be used with ClockworkMod Recovery. So I was desperately looking for other ways of creating a backup. If I follow the steps in the above article will it create a Backup ROM for me? I rooted my device and then unrooted it again, both using GingerBreak and am not able to root it again. However I am able to login to adb shell as root since my ro.secure is set to 0. If I run the above steps using the root adb shell, is it enough? Any help will be greatly appreciated.
