Nook HD+ Complete EMMC Backup and CWM Format options ?

[sorrowuk]

How can I do a complete backup of the emmc so that if anything happens or I brick something I can restore it and all my device specific stuff will be fine.

I'm on windows so I guess I just need to use something like dd ?


Also does any of the Clockworkmod functions like the format options and Wipe Data/Cache do anything to the emmc or does it only touch the sdcard ?

I am using verygreens latest cwm.

Verygreen's CWM just does things to SD (except cache, which it shares with emmc). Yes, you can dd it. I did mine. I did it from inside CM10.

Can you tell me the command to type if you don't mind.

I don't know exactly the format of the dd command

I don't know exactly the format of the dd command

dd if=/dev/block/mmcblk0p1 of=/storage/sdcard1/xloader.img

Do that for each of the first 9 partitions, changing the p# and name saved to. Do this in Terminal Emulator in su mode.

Xloader
Bootloader
Recovery
Boot
Rom
Bootdata
Factory
System
Cache

You don't want to do /data (10) as it is huge. This is the same for the HD. Save the .img files in case you need to reverse the process, which I have had to do on my HD on one partition.

The most important one to do is factory (7). It has a backup of your vital system configuration files and also holds the factory zip for resetting to stock. Everyone should do at least that one and keep the file safe. It will be about 450MB.

Cool thanks

And writing them back is like this I guess ?

dd if=/storage/sdcard1/xloader.img of=/dev/block/mmcblk0p1 ?

Yep, if=input file, of=output file. These are images of the partitions so it has the format and file content all there.

EDIT: I just added this information to my HD/HD+ tips thread.
