Hi - I had trouble downloading the tiny umbrella - I ended up not needing it - nor the firmware - this is what I did thanks to f4780y's instructions I was able to fix it myself - I first successfully jailbroke my ipad1 (I know - relic) and had to activate it again - and got confused with whether or not to start it like a new ipad or restore...I started like new, but then itunes was being picky - so I (now I know - DO NOT DO THIS) reset the data on the jailbroken ipad and got the spinning wheel. I found this site - I did the DFU mode restart wrong, and got the itunes and cord icon - i did it wrong again and I - got the apple - I did it a third time, and got it right - blank screen - then I did it one more time to get the apple back and turned on itunes because the firmware was taking forever to update. My computer was also busy downloading drivers each time I attempted the DFU mode - When I looked at Itunes - it was asking me if I wanted to start my ipad as a new one or restore from a backup I had done. I said new...and when I opened it up, it was restored to 5.1.1, AND still had CYDIA!! WHEW! I think I got REALLY lucky..... I had NO idea how to do the DFU prior to finding this post - THANK YOU!!!
