So, here are just a few helpful tips for you before getting your 360 flashed, JTAG'd or RGH'd. There are plenty of 360's that can be modded, and some that can't so this thread is to help you determine whether your console can be modded or not. The images are small, click any of them to enlarge them.

As of now, ANY phat other than a Xenon, and ALL slims can be glitched. With the release of new universal .ecc files, you can retrieve the CPU key from any console on any dash (excluding Xenon's).

As of now, for a reliable glitchable ANY slim will do. With the right chip, wiring and time you can have a quick booting slim regardless of dashboard or motherboard version. To tell the difference between a corona or slim see the image below. Click to enlarge it.

If your console uses 10.83a as shown in the image, you will have a trinity motherboard. If your's uses 9.86a then you have a corona motherboard, which has been exploited as well. So as of now all slims on ANY dash *as of now* can be RGH'd including the newest 360e model.

If you want to check whether or not your console is a 4GB model or not, just go to the memory tab in the system settings screen. If you see an internal memory unit then you have the 4GB model.

To check your dashboard version, simply turn on your slim. Then go to Settings> System> Console Settings> System Info and view the consoles information. It will tell you which dashboard your 360 is on.



Flashing info

Currently all slim drives can be flashed, but only the 16DG4S drive doesn't need any additional hardware. The newer 16DG5S and Hitachi slim drives will need an LTU replacement PCB, as well as have to be RGH'd to get certain info. To check if you have a Hitachi or LiteON see the image below.


If you have a LiteON, then you will have to see if you have a 16dg4s or 16dg5s drive. A quick check would be to look at the MFR date. If your slim was made before August of 2011 then you most likely have a 16dg4s drive which can be flashed.

If you want to be 100% sure on which drive you have, you will need to open up your console and check the top sticker. Circled in red below is what you need to look for.

JTAG info
( Click to show/hide )
If you want to JTAG your console, you have two requirements. It MUST be made before June of 2009 (I think the cutoff date was the 23rd of June) and you must have a dashboard of 7371 or lower. How can you check? Well for the date, look at the Manufacture date, pretty simple. To check your dashboard version, you need to go to the console info tab and check your dashboard version. If it's 8955 or above, you can't JTAG your 360 since the SMC hack method was patched. If your dash is on 7371 or lower and made before June of 09, then you can most likely JTAG your console. Some consoles on 7371 already have an updated CB though, so there is no way to be 100% sure without dumping the NAND.


RGH info

If your console has a dashboard version between 8955 through 14699 then you can use the good old RGH method which is by far the best of the current RGH options. Boot times can be anywhere from instant to 20 seconds. If your console is on dashboard version 14717 or above then you will need to use the new RJTAG hack, or the previous RGH2 method. I strongly do not recommend the RGH2 method as boot times are incredibly random and can take hours of time tweaking, and getting all the little settings right before the console has "ok" boot times.

Note that any current RGH or RJTAG method is incompatible with xenon motherboards.

All phat 360 drives can be flashed now with the latest FW apart from the Samsung and older Hitachi drives which do not need LT3.0 to play the latest games.

To see which drive you have, check out the image below.


As of now, all BenQ LiteON and Samsung drives can be updated with the latest FW and have all games working without any issues as long as you burn them correctly.
If you have a Hitachi just check which revision you have. If it's 32-59 then you can flash it to 2.0 without any issues. If you have a 78 or 79 then you will need to flash with the latest 3.0 firmware
