2.What items do I need to open the 360 and how can i preserve the warranty sticker?
3. Once my 360 is connected to my computer, step by step what do I need to do?
4. What is the easiest way to back-up games? I have heard of kreon flashed samsung drives, will these be as simple as putting it in the empty bay on my computer, inserting a 360 game and using XBC?
5. What is better, Xecuter 360, just a simple firmware flash or the 360USB?
6. Is 50+shipping the cheapest I will find the Samsung drives that can be flashed?
7. (Your opinion) I have very little understanding of computers,(I know how to rip/burn games, can install a PCI Sata slot), should I do this flash myself or pay about $50 for someone else to do it for me?
1. How do I flash my 360 w/xtreme firmware?
There are tutorials here all about this at the top in bold
2.What items do I need to open the 360 and how can i preserve the warranty sticker?
Hair dryer, a razor blade, wax paper and some patients
3. Once my 360 is connected to my computer, step by step what do I need to do?
again, see tutorials
4. What is the easiest way to back-up games? I have heard of kreon flashed samsung drives, will these be as simple as putting it in the empty bay on my computer, inserting a 360 game and using XBC?
YES
5. What is better, Xecuter 360, just a simple firmware flash or the 360USB?
USB is only for one specifica Hitachi drive, The blaster is great if you have to update firmware, and the simple flash is what most people probably did.
6. Is 50+shipping the cheapest I will find the Samsung drives that can be flashed?
Most likely around that price, Yes
7. (Your opinion) I have very little understanding of computers,(I know how to rip/burn games, can install a PCI Sata slot), should I do this flash myself or pay about $50 for someone else to do it for me?
Well if you know someone who can do it and you trust, i would pay them. The blaster 360 and SATA card that you MAY need would cost more then $50
