Ok so, i have my blobs saved. I'm on winxp. Latest itunes, latest TinyUmbrella.
I put my phone in DFU mode (black screen), restart my computer, plug phone in. iTunes opens up and says iphone has to be restored blah blah, i hit cancel and close iTunes. I open TU, which at this point doesn't recognize the iphone either, since its in DFU mode. I hit "Start TSS Server", then start up itunes, and select the 4.2.1 image I have saved on my desktop. 5 minutes later, i get error 1013 (which is the same as 1003/4), but then when I try to kick my phone out of recovery with TU, it reboots right back to recovery. hmm
