My system is a 4.1E and I tried to follow the steps of this thread. I have gone easily thru the first one, downgrading to IOS15. When I tried to load the Trucha Bug Restorer on the IOS15, step 2, I received the DSI error message. I have tried to search on this error but I only found replys related to USB loader instalation. The error msg is very similar to M.K post on 2nd page.
link is the following:
The interesting thing is that the black error screen pops up when I am moving through the options to get to IOS 15, it is not when I press any button.
I am very new to this and I appreciate your help!
