[Q] Initial backup/ image for new device
Very noob with a very noob questions
I read a lot about backups etc... Some have to be rooted first...
I'm used with my Windows computers to make a genuine unstarted system image (Ghost, now Acronis)
When I have a new computer, I take out the main HDD and make an image or boot with an Acronis boot disk and make an genuine image, can I do something similar with Android devices?
Is EFS the system image or just the system files, restoring an EFS backup is enough to make a device bootable again without Root?
Windows PC suitable for this? ADB I guess...
Perhaps it's not possible because I haven't see any topic about making an genuine image before first start of an new device or restoring a factory image... Every time Root is involved
Thank you to make me a little wiser
Sorry for my poor english
