Ipad 2 home button not working


I bought an Ipad 2 with cracked digitizer and charging connector.
When i bought it, the Ipad was discharged.

After replacing digitizer and charging connector I charged it a while and when it booted the message "Ipad disabled" came.

I tried to connect it to iTunes, but i don’t get any confirmation on Ipad for allowing the iTunes to connect.

Also, tried the recovery method with starting with Home button pressed, but it booted normally (with "Ipad disabled" message).

Seems that home button not working or this might be because the Ipad is disabled?
