- 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
fastboot boot. 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. +

- #73 lists lots of issues with the device, and additional information, such as fastboot's partitions output +
- This might be the same phone? +
