I'm in a similar boat, I rooted mine but before I start unlocking and flashing, I'd like to make a backup of the current state of my phone.
How can I make a complete phone backup (with all partitions)? I was thinking of using Nandroid, but as @einfachgaer
mentioned, making a backup of the TA partition is one of the steps to take. If the TA partition needs to be backuped seperately, I suspect a Nandroid backup is not enough
(it only backups /system and /data, without a ZL-specific patch?) as I want the backup to be a complete package of the phone's NAND, including the TA partition and any other (device/manufacturer-specific) partition that may be in there. cat /proc/partitions shows 27(!) of them.
So, I'm looking for a full phone backup without initially installing any custom recovery, as I think the original recovery is part of the current phone's current state and I would like to make a backup of it.
Can anyone recommend a backup method that doesn't require overwriting the phone's current configuration and will allow me to get to my exact current phone state?
I now asked this question here
as well, I'll be editing those posts to reflect the correct information when I get it.
Perhaps 'nanddump' and 'nandwrite' from MTD-Utils
(Updated download link
) are suited for a full RAW Android device NAND backup of all partitions, even those with unreadable filesystems (bootloader) and/or additional (hidden) data beyond a filesystem?
