BigK,
There is a link to the upgrade/downgrade file in the post immediately following your request for it. The instructions are included in the zip file.
Please understand that people on here will be much more helpful if it looks like you have tried hard to find the answers before you ask on this board. This topic ONLY has 20 pages and if you look you will see that I never posted once until I had success, despite the fact the I DID have issues.
Also I knew what you meant when you asked for help on your downgrade, (because I had seen and read all of your posts) but for your own benefit, you need to be more specific, especially in a post asking for help. The words downgrade can be used to mean several very different things pertaining to this subject.
