Dump an image of root and eMMC.. how to?

[Dany-69]

Hi guys
First at all, excuse me for my english
By the way... i've searched al lot here and on google about a way to dump the image of the root and the eMMC, but unfortunately without a result..

I'd like to create some images that can be flashed throught the maemo-flasher with a simple command, just like the FIASCO images..
This way everybody could create his own "rom" with all the desired advanced personalizations (like transitions, boot videos, power menu, cpu clock ecc ecc), softwares and settings ...
Something much more easy and fast than a backup IMHO ..

Excuse me if this question has already been paid.

use dd?
for rootfs, dd if=/dev/mtd5 of=rootfs.raw

Exellent idea as that would be a good way to restore phone to "last known working" similar to the system restore in windows.
Getting close to my idea of uninstalling completely problem apps or getting the os back to it was prior to a loop or "bricked" situation.

It also might be a good way to compared the leaked PR1.2 vs the supposedly stock hong kong PR1.2

im a inexperienced linux user.
how would i define the destination path to store that "rootfs.raw" on the sdcard / or on the 30 gb partition (users files)?

Wait wait ..
What does this command do ?
Does it create directly a file that can be used with the Flasher?
and where does the command place the file ?
Tnx

dd (data definition), copies bytes from if (input file/device) to of (output file/device).

Not sure if it creates a file that can be used with flasher.

It places the file in the directory you run the command from to have it place the file in the memory card set of=/media/mmc1/rootfs.raw

Also creating a dump of emmc should probably not be done - just copy the directories to an ext3 partition to preserve permission info (ext3 memory card perhaps???), otherwise each time you do it you will get a file thats 2GB big, which will wear down the internal flash.

Only opt needs to be copy to ext3, MyDocs can just be backed up on PC as it's just FAT32.
