0xffff binary package in Ubuntu Xenial s390x

 The ‘Open Free Fiasco Firmware Flasher’ aka 0xFFFF utility implements
 a free userspace handler for the NOLO bootloader and extended features
 for flashing, dumping and getting information for the Nokia Internet
 Tablets. Thus it's a free alternative to Nokia's closed source flashing
 utility called flasher.
 .
 Supported operations currently include, but are not limited to:
  * generating and unpacking FIASCO images on local device
  * editing Maemo firmware packages
  * flashing any kind image type to Maemo devices via USB
  * "cold" flashing for devices with bricked bootloaders
  * direct kernel boot without flashing it to NAND
  * changing configuration of Maemo device (R&D flags, HW revision strings, ...)
 .
 Currently supported are the Nokia 770, N800, N810, N810w and the N900.
