iTunes does not allow SHIFT+RESTORE
I've been having a problem since a few months ago that I cannot find a way out of.
When you want to do a restore of a custom IPSW in a iPhone you have to do SHIFT+RESTORE (since I'm a windows user), but my PC does not allow that. It completely ignores the SHIFT key making it impossible to restore into a custom FW.
I'm tried almost anything I could think off (new itunes, downgrade, upgrade, everything) and now I don't no what else I can do...
I googled many things and I found out that I'm not the only one with this problem, and no-one figure a way out of this yet.
Oh yeah the SHIFT key actually works, and I'm on a Windows Vista 32 Bits.
Thanks in advance.
