I don't know what exactly happened, but after installing my developer profile to my iPhone it started asking me to enter "Passcode" as if it "Custom Alphanumeric Code", however since the purchasing of this iPhone I have been using "6-digit Numeric Code". I have never changed it and now my phone is locked and I don't which passcode it needs.
I can't restore it, because it contains important for me data.
What are the options?
Hi there,
You might have better luck asking this question over in Apple Support Communities run by Apple Support.
Did you try your account password?
No, I don't have that many attempts left

I also recently installed the latest software update.
I also can see that this sometimes happens, even after software update, check this threads and similars:
