Hmm... Come to think of it, I did successfully perform a reset on my L635 this past Saturday without the SIM card. I had unlocked the phone on Friday before.
Sounds like the problem has been nailed down as to the "cause", and there are 2 solutions/workarounds now. Either temporarily place the SIM in the phone, or get the phone unlocked. Let us know how it works out.
