How to Create Full ROM Backup? And a Few Other Questions...

[vampirefo.]

Just use the mount command to see where your /data /cache /system are mounted from that you should be able to determine the rest.

Since the MID7035-4 has been rooted I have been trying to dump the system for recovery, but it appears the nanda, nandc, and nandg are not in /dev/block. I have attached a screenshot of what appears in /dev/block as to potentially get any hints as to what needs to be backed up to make boot.img, bootloader.img, and recovery.img. A

find / -name "nand*" -print

as root did not show anything either. Any thoughts would be appreciated.

The list from mount looks like

I found a list that said
nanda = bootloader
nandc = BOOT\Kernel
nandg = recovery

so from the mount point list is
/data the equivalent nanda
/system the equivalent of nandc
/cache the equivalent of nandg

Thanks for any information.

post output of

cat /proc/partitions

I see you are using UBI File-System, I don't think anyone will touch that filesystem, with a 10 foot pole.

[Folken]

The output is below. The device came with the UBI filesystem as far as I know. What are the issues with that filesystem compared to others? Thanks for your help with this, I am still trying to get educated on things.

Now try this command

cat /proc/mtd

This above command should tell you what you want to know.

Here is the info from /proc/mtd . If you can tell me which mtdX relates to boot.img, bootloader.img, and recovery.img . I can try to get a dump script working. Thanks again.
