my iphone is been disabled due to forgot passcode and is not getting started with any options like itunes or manual process on app stores.

i changed the passcode yesterday of my phone and forgot passcode, tried all possible ways to recover or restore the iphone, removed from apple id, tried switch off and long press home screen to see the recovery mode on phone, also tried find my phone option to delete the device, however nothing is working with my phone and i am to much upset as it has all the important data and doc.

please help me urgently on this.
