Status
 a boot.img file with kernel, initramfs and dtb file from pmOS does not work. alexlep has a boot.img file from the vendor somewhere (extracted from the device?), that works when flashed via. It can not be extracted like a normal boot.img file, as reported on IRC. Probably the extraction tool can't handle the files.  according to alexlep, there is a 512b header in front of the kernel and initramfs: ramdisk and kernel has 512 bytes added in the beginning of the files custom header with file description   ...and simply prepending that header in front of a custom initramfs/kernel does not work, as he reports. </li></ul>

extracted boot.img, first bytes of pmOS initramfs (not working):
