Locked out of iPhone7, how to reach code input (or restore to current firmware). Please help!

hi all. new here (and english isn't native language) need help. i've been ill while , yesterday able jailbreak iphone 7 (on ios 10.0.1). morning entered code able use touch id. later when tried unlock, didn't. quite sure of code, after tried others in desperation. locked on screen 'iphone locked. connect itunes', says there should unlock using code (duh...). dumbfounded , don't know do. being sick doesn't help.

mean lost jailbreak , have restore ios 11?
have 10.0.1 ipsw on computer.

i've tried far:

• several tries input code.
• then googled happened , made itunes backup, after tried restore previous itunes backup specified. never unlocked, not sure if restore worked. option 'restore , update' ("herstel en bijwerken") in itunes.
• when power on i7 see letters "iphone blocked, connect itunes" first screen after apple logo (screenshot). when connect iphone , open itunes, gives me these options translate in english 'more info', 'try again', 'cancel'. on iphone7 same screen, no code input.
• however, when enter dfu (by holding power, volume down well, releasing power) different message in itunes, screenshot here, iphone in dfu mode.
  not know if not reset firmware 11. or real option?

there way go code-input screen, can try different combination? or last mentioned itunes message possibility?

in other words, lost me? please, please help. :'(
