Hi everyone. It has recently come to my attention that a number of people are having trouble with title updates on Jtags/RGHs, typically with FSD's automatic Title Update system as well as not updating when put in the cache folder. I've found a way to make them work however it may take a little more time to do.
First you're going to need Horizon which can be acquired with a simple Google search, I am not spoon feeding you.
Second of all you'll need a transfer cable, at current I don't know how to do this with a USB but I assume someone will soon tell me.
First off connect your HDD to your PC with a transfer cable then open Horizon as administrator so you can definitely find your HDD.
Once open you should get this screen: [ Register or Signin to view external links. ]
On the right.
Click on the Title Updates tab and you should see any TU's you have installed, or lack of for that matter.
Now you want to right click and select 'Inject File'. Then navigate to where your Title Update is located and open it.
Once transferred congratulations you have successfully installed a Title Update!

The main source for title updates is XBUC which can be found through a simple Google.
I hope this clears up any issues you may have had installing TU's and finding them.
