It would be better if we could somehow install the new update onto the virtual drive on pc and then transfer the contents to usb and run. Then we can have "updated" systems. But like someone else mentioed. IF we launch a game it resets the sytem and we would return to the original firmware on the hdd and not be able to do anything but be prompted to update again.
Unless someone could get the JB to launch from a backup usb version or external which had the 3.41 on it and the actual hdd had the update. THen we could simulate the hack on the real system. Kinda seems impossible but is a nice idea.
Like if it could when the system is being ran point to the usb with the 3.41 information and then execute that instead of the original.. Wishful thinking..
This would be very nice and have a useful perpose. Right now by doing this you are really just loading your own firmware... Which is cool because like it says... you can change what you want and not be online and see what happens. Good for seeing what does what.
