I have my iPad completely stucked after trying to upgrade to iOS 5 from 4.3.5. Upgrade failed with iTunes error 6, just after the upgrading firmware procedure. The iPad is gone in restore mode and iOS 5 is not installing. I already read all info on error 6 and got thru storing TCP params on Windows 7 x64. I also tried the restore from another PC running Win7 x86 and on a MacBookPro running Lion updated at last release: iTunes is giving always error 6 in the same moment on all platforms. ITunes is updated at the last available release. I tried also to restore after putting the iPad in DFU mode. My iPad results completely blocked and is out of warranty, since I bought it 16 months ago. What can I do? Is it possible that I've lost it with a simple upgrade and cannot do anything? Any help would be appreciated!
