iTunes detects ipad 2 in recovery mode but doesn't recognize its capacity, software version and serial number. I tried different USB ports, win7 and win xp OS and it makes no difference. I also tried to restore firmware with itunes in DFU mode but I always get error 9. Tried to kick it out of recovery mode with tinyumbrella - doesn't work, tried to save shsh blobs - doesn't work. Acquired ECID number using USB device viewer and created custom device in tinyumbrella - nothing changed. I just want to know if there's something which I haven't tried yet to fix it because I won't take it to apple service center - I'm making effort to fix it at home.
