Hi .. i tried it but gave me this error
root@hero2lte:/ # dd if=/dev/block/sda14 of=c:/system.img
dd: c:/system.img: No such file or directory

i try the other backslash with the error

1|root@hero2lte:/ # dd if=/dev/block/sda14 of=c:\system.img
dd: c:system.img: Read-only file system

any ideas ?

My data block is "sda45"
These commands will give me same files? Or dd creates specific .img file?
Code:
adb pull dev/block/platform/soc/1da4000.ufshc/by-name/userdata  D:\folder
Code:
dd if=/dev/block/sda45 of=D:\folder\userdata.img

How do I read these dumps? I can create them successfully by gziping, copy them to my desktop, unzip, mount and in Linux Reader I get this message:

When I look at a traditional Unix box, in / directory there is bin boot dev etc home mnt media sbin var etc... but these arnt separate partitions. All partitions are in dev/sda1 where a is the hard drive and 1 would be the first partition on it. So theres sda1 2 3 and sdb1 2 3 and so on...

But in android these are all separate partitions am I right?

yes
you can drop into adb shell to check by running
blkid
or
mount

to find your partitions.

newer devices you could also do a

ls /dev/block/bootdevice/by-name

Do you see a file called sda1 or sdb1 in your dev folder?
