Default [Q] Can I flash a 4.2.2 ROM on HBOOT 1.57?

As title,

Is it possible to flash a stock 4.2.2 rom on this hboot?
Wanting to downgrade my hboot but do not want to have a soft brick afterwards, so I want to have a ROM and recovery on there already compatible with the downgraded hboot.

Thanks

Then you need to look for a HTC guru reset

Got one, I'm just scared of bricking my device again as I tried flashing firmware from 3.xx to 5.xx and ended up bricking it.
Will this happen on the way down too?

Is it as simple as flashing firmware.zip, then a custom recovery and then a custom rom or guru reset?
