From my point of view,
there is no need to flash your onboard tsop,
cause you may render your xbox useless,
from a wrong flash.
For this perpose you can add a Bios replacement kit,
that is well know as a modchip...
Nowdays they are extra cheap,
and thanks to Plug&Hack installation,
you always have the chance to remove the modchip
and have your console back to the original point!
I have been flashing onboard tsops for more than 2 months,
and now many people are having problem.
Also do not forget that M$ can find your hacked console,
and this has been confirmed in the Xbox Live.
So, you never know if there is going to be a game in the near future,
with mod detection ability that as soon as it will detect your hacked bios,
will cause problems in your console...
So, flashing your onboard tsop is only recomended from our team,
to reflash it with the original bios,
if somebody has upgraded in the past,
and always check that your console is really include a modchip,
when you send it to technicians to mod it for you...
