it will work with ext2rd.

problem is that ext2dump is quite old, I just kept it around for historical reasons.
now deleted from the repository to avoid confusion.

ext2rd dump failed. what should i do?
C:\extfstools>ext2rd.exe system.img.ext4 ./:testdir

ext2rd will now create directories on windows.

But there still seems to be another problem, you will get 'blocknr too large' during extraction.
also, if you look at the output of 'ext2rd -d system.img' you will notices at some point you get invalid data.

I am looking into this.

I think the problem is in this ext4fs feature, which is not yet supported by ext2rd:

• Flexible block group metadata location (EXT4_FEATURE_INCOMPAT_FLEX_BG)

Note that I will not solve this right away, it may be a while before I have time to do this.
