Like the title says, My captivate refuses to take the root. Tried using one-click, and doing it manually. I'm doing this on a mac, but others have so I dont see the hold up here. I get the update.zip on there, or let OCR do its thing, then it will go into recovery like it should, then I go to select update packages and it refuses to install. says something like "E:signature not found installation aborted" So dont know really where else to go from here.
