I was trying to install 4.2.1 while using Tinyumbrella to avoid upgrading my baseband. Now my iphone 4 is stuck in recovery mode and the exit recovery button will not kick it out. I had saved my SHSH blobs prior to upgrading, any ideas how to get it out of recovery? Everything I've been able to find says use tinyumbrella to kick it out which obviously is not working. I do have the latest version of Tinyumbrella btw.
