I've been getting my iphone ready to sell unlocked. It was on 4.2 and was trying to get it to 4.3.3. I'm having trouble restoring it fully. I downloaded tinyumbrella and saved all my shsh blobs and ran the TSS server. Opened iTunes and restored to 4.3.3 but right when it seems like it's done I get an error. An unknown error occurred (1). I can't seem to figure this out.
