Quick route to RGH/JTAG:

Before any decision can be made about which modification to do or how to do it you first must know exactly which model and motherboard console you have.

We can first narrow this down by the 3 console types, and then further identify the specific motherboard type from there. We've laid that out in our identification guide.

Once you know your 360 version and motherboard type, reference the table below for a quick and easy way to get a recommendation on what method to use to mod your console. More DETAILED data is avialable under the GUIDES section.

Then What?

 Notes: 

Phat Xenon
(on 7371 or below)
JTAG (SMC Hack)
 2qty 1N4148 Diodes

 Consoles on 7371 are EXCEPTIONALLY rare now. Be sure! 

Xenon
(any dash over 7371) 
Don't bother

while there are methods available for RGHing a Xenon they are notoriously unreliable and unstable. 
Seriously - RGH on a xenon is not worth it.  
Opus / Falcon / Jasper
(dash 7371 or below)
JTAG (SMC Hack)
2qty 1N4148 Diodes
Consoles on 7371 are EXCEPTIONALLY rare now. Be sure! 
Opus / Falcon / Jasper
(Any dash over 7371)
RGH 1.2 with Matrix
or
RGH 1.2 with CR Rev C 
One of the easier mods - you do NOT need the onboard crystal osciallator on your glitch chip. 
Zephyr
(any dash)
Don't bother

while there are methods available for RGHing a Zepher they are notoriously difficult to dial in.
Seriously - RGH on a zephyr is super annoying. NOT a good first mod!!!
Slim S Trinity
(any dash)

S-RGH with Ace V3
OR 
Muffin CR4 with Matrix or
Muffin CR4 with CR Rev C

Best combo of easy mod and a reliable console. 
If you can, this should be your first RGH
Corona 16mb Nand
(any dash)

RGH 2.0 with Ace V3
OR 
Muffin CR4 with Matrix
Muffin CR4 with CR Rev D

Default timing file on the Ace.   
If Matrix, you DO need the crystal oscillator version. 

Can also need postfix adapter for some coronas.

Corona (4gb Nand)

RGH 2.0 using Ace V3
OR 
Muffin CR4 with Matrix
Muffin CR4 with CR Rev D

 
 SD tool instead of Nandx or JRP for 4gb nand consoles. 

You might still need a JRP or Nandx to program your glitch chip. 

Default timing file on the Ace.   
If Matrix, you DO need the crystal oscillator version. 

Can also need postfix adapter for some coronas.

A word on the guides and tutorials:

I have already produced tutorials that cover each of the methods advocated for in the table above over the past several years. As it is now 2020 the Xbox 360 has been out for 15 years! With that in mind there is a lot of old information out there - the table above I will keep updated to current methods, that will actually work in 2020 and on the latest dashboards!
Disclaimer:
In these tutorials, I make use of amazon affiliate links to many of the generic tools I reccommend. The affiliate link means I will get a small kickback from Amazon of that sale if you buy through my link.
I also plan to make frequent mention of my own web store where you will be able to buy many of the special tools. I really appreciate those of you that will choose to support me by purchasing some of your supplies from my site
