Finally
Your Xbox should now boot and prompt you to select your language etc etc. You should obtain and apply an update that contains a vulnerable kernel (4532 or 4548) and obtain your CPU fuse data.

There is a final step to the process to cleanup and stealth the downgrade. The CB section will still contain a “suspicious” version lockdown number and once the CPU fuse data is available this should be fixed using the NAND flash dump tool. You can do this one of 2 ways:

1) Patch the CB version lock down to 0 in your new, vulnerable image or, better
2) Increment 1 or both (if both are present) of the the CF lock down counters by 1 in your original flash image (the 4532 update will blow another eFuse). Reflash your Xbox.

Unless you have applied the maximum number of updates (and blown as many eFuses as possible) removing R6T3 is NOT recommended for the average user. It’s small and difficult to work with and damage may result.
Known Problems
Sometimes the Downgrader Tool will hang when it starts, this appears to be due to the Infectus being in a strange state. Power off the Xbox, remove the USB cable from the Infectus, remove and then replace the Xbox power cable, replace the Infectus USB cable and try again.

This was patched a lonnnggggg time ago. Some one erase this, you can jtag more consoles than you can downgrade with the TA, so there is no point to downgrading, so this is outdated, and pretty retarded to post a tutorial without actually researching how it works. Besides, the new CB (7371>) blocked the 1888 dash, which this method requires inorder to work, so this does nothing for you.

this does not work, u cannot downgrade a dashboard, u will blow an e fuse
Ugh.No.

When you upgrade it blows an efuse, basically the new dash is designed to read that efuse value and think its ok, but any other dashboard revision kernel would read it and think its not ok and therefore not boot.

So no, when you downgrade you dont blow an efuse, basically because when you upgraded and blew that efuse you cant upgrade.
