Ive found a way to get the xbox one to be able to play xbox backups through several hardware mods,
step 1; dissasemble the xbox one.
step 2; replace hdd with xbox 360 hdd.
step 3 replace disc drive with xbox 360 disc drive pre loaded with iextreme.
step 4, replace motherboard with xbox 360 motherboard.
step 5. reassemble
step 6. Play xbox games on your modified xbox one.
Why is this surprising? The 360 took about 2 years and is nowhere near as complex as the xbox one. C4eva said he is making headway with flashing the drive.
