Random information

  • Obscure phone:

    This is just another clone from millions of devices from Chinese manufacturers.

  • MT6582 CPU
  • Product code F090_GPS_KK

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 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.

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