Phats:
The nice thing about identifying motherboard types on a Phat Xbox 360 is that we can 100% do it externally, without the need to open up the case at all. In order to determine the motherboard type of any phat console, there are just two items to check:
Does the console have an HDMI port?
What is the power usage of the console? (Determined by examining the power socket on the back of the console)
It's trivial to inspect the back of the Phat Xbox 360 to see if it has an HDMI port or not. Here is an image of a Xbox 360 Phat that does have an HDMI port and it's labeled:
Now that you know if your console has HDMI, we can look at the power socket on the console and compare to this image:
So, essentially what you want to see is the precense of a HDMI port, plus either of the two power sockets to the right side of the image above which would mean that you have a Falcon or Jasper console, which are essentially the only Phats worth modding.
Once you've confirmed you've got a Falcon or Jasper console you can visit our
RGH Falcon or Jasper Guide for detailed instructions on how to mod your console.
Slim S:
The nice thing about the Slim series is that there are only 2 possible motherboards within them:
Trinity (Most consoles with a MFR date of 07-2011 and BEFORE)
Corona (Most consoles with a MFR date of 8-2011 and AFTER)
Both Trinity and Corona motherboard consoles are all 100% RGH'able. You do need to determine your specific motherboard type so that you can get the correct supplies. The dates mentioned above are about 90% accurate as far as determining your motherboard version but I have seen some consoles that were Trinities with a much later MFR date, and I've seen a few Coronas in consoles with earlier MFR dates.
To be 100% certain you'll need to open up the console and inspect the motherboard.
The quickest check to tell a Trinity from a Corona is to examine the J2C1 and J2C3 headers (JTAG header).
In a Trinity motherboard the headers are vertical and paralell to each other like this:
If you have a Trinity console, there is no need to check anything further. All Trinities, even the ones that have the 4gb add-on, have a 16mb nand and are modded in the same way. One trinity is the same as any other. You can now go follow the
guide for Trinity consoles.
In a Corona motherboard one header is vertical and the other is rotated 90 degress to be horizontal like this:
If you have a Corona console, you'll still need to determine if you have a 4gb Nand or a 16mb Nand. This is easily determined by simply powering up the console, visiting the storage menu, and looking for a ~4gb onboard storage unit. If an onboard storage appears then you have a 4gb Corona and should use our
4gb Corona Guide and if you don't show an onboard storage then you have a 16mb Corona nand and should use our
16mb Corona Guide.
If for some reason you're unsure about checking the storage menu on the console, or want to be really-extra-double-sure that you have either a 4gb or a 16mb Corona you can visually identify them by inspecting the nand chip on the console:
Slim E:
The Slim E series console has two motherboard possibilities, and it is important to determine which one is in the console you want to modify:
Corona (just like in the Slim S series all are mod-able)
Winchester (as of 2018 no current method exists to mod this console) :-(
As with the Slim S series console the MFR date can be a good indicator, but it is not 100% reliable. As a rule of thumb:
Consoles with a MFR date of 06-2014 and BEFORE are likely to be Corona
Consoles with a MFR date of 07-2014 and AFTER are likely to be the non-modable Winchester motherboard.
The only way to know for absolutely 100% certain is to open up the console and remove the heatsink and take a look at the XCGPU. In the Corona consoles they stil have an IHS (integrated heat sink) an on the Winchester motherboards they do not.
Here is an example Corona XCGPU:
Here is an example of a Winchester XCGPU:
The bad news here is if you have a Winchester, you're just out of luck. As of today in 2018 there is still no method to do any hardware modificaitons to the Winchester console.
If you have a Corona console, you'll still need to determine if you have a 4gb Nand or a 16mb Nand. This is easily determined by simply powering up the console, visiting the storage menu, and looking for a ~4gb onboard storage unit. If an onboard storage appears then you have a 4gb Corona and should use our
4gb Corona Guide and if you don't show an onboard storage then you have a 16mb Corona nand and should use our
16mb Corona Guide. There is no difference in the modding process for a Corona that was in an E series slim vs one that was in an S series slim.
If for some reason you're unsure about checking the storage menu on the console, or want to be really-extra-double-sure that you have either a 4gb or a 16mb Corona you can visually identify them by inspecting the nand chip on the console:
