[Tutorial] Backup your NVRAM

[Alon]

If you don't have a rooted phone droidtools won't backup nvram. The only way to backup nvram is using the information in the scatter file and use the readback funtion from flashtool to make the backup of your nvram partition
(you have to do this manually, so you need to know what information to use from the scatter file, else forget this post).
This will include all information, binaries and config files, even the ones used for the wifi mac address and a lot of calibration files.
You can later restore it to your phone simply by downloading the file with flashtool, no need for any conversion as it is a raw binary file.

Hi, so in order to make a full backup of a pristine brand new non rooted phone, then I should use flashtool?.
Do you have a link to a tutorial of how to make a full backup with everything included before I start messing with the phone`s ROM?

Thank you.
