What is a Backup ROM (Technical Answer Required)

    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.

    Hi 14gautam!

    Welcome to AF :) I have moved your thread to the ROM section where they will be better able to explain this.

    Cheers :)

    A Nandroid backup consists of the /data partition (data.img), /cache partition (cache.img) and the /system partition (system.img) all nicely packaged in a backup folder with an MD5 check sum.

    It is best IMHO to use a custom recovery to do this.

    Hope this helps.

    Thanks SUroot :)

    I flashed the recovery with fastboot using the ClockworkMod Recovery image and took a backup and was able to restore it back.
