Hacking Soft-modded to un-modded

[Ergo]

Hi all,

I can't seem to get a straight answer to this question anywhere, though I think I already (unfortunately) know it:

I want to make my 360 legit, BUT due to the death of my desktop PC, I can't reflash it back to stock So my question is: If I update normally (via disc), am I in danger of being banned from Live? In other words, do I *have to* flash back to stock to go on Live at all w/o fear?

Thanks for any light

If you're on dash 12xxx or lower You can grab the lastest dash update from MS and put it on a USB drive and update the console.
If you're on dash 14699 you cannot flash the drive back via USB/DVD updates.

However this is not advised and could potentially flag your console for a future ban.

I could flash the drive for you if you want to.
Only thing I ask for it is that you pay for shipping costs ;p
