first of all, please punctuate.
if you write everything like this it will be a mess and no one will understand you do i make myself clear now thanks
if you have dash 14699, leave it there. do not update. new updates alter the bootloaders and you might loose the ability to hack it specially for phats (at least for now)
if you try to update and do not know the proper methods to do so, you also might brick it or at least, render it unbootable until the coolrunner is deactivated or desoldered
if i understand the other boot question, your xbox is only able to boot if no drive is connected? is it a slim or a phat? you can try these steps:
- without hdd, boot via power button
- without hdd, boot via eject button (to XeLL)
- with hdd, boot via power button
- with hdd, boot via eject button
wait at least 30~40 seconds before giving up as some consoles are quite stubborn if the wire length/placement is not tweaked after installation.
