@seaniko7: I have to thank you for everything you're doing. Your achievements are really great.
I already thought it should be the uImage-initramfs.
I did all the steps and my boox is booting up and checking for updates for approx. 30min now. Is it installing something or does the first boot up need some more time?
I don't think it hangs.
I extracted the rootfs with usual tar command - that should preserve the symbolic links
(I think, am I right?)
@all: Somehow my boox won't run the dd command through an oar- script as it does with cp and others. I entered the command in betty boox terminal emulator.
