ROMs What is a Backup ROM (Technical Answer Required)

[14gautam]

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.
