Is my iPhone useless?
My iPhone is disabled, and as home button is broken so I cannot enter recovery or DFU mode. I am about to throw it away so is there anything else I can do to get it working again
iPhone 6s Plus, iOS 15
Hello,
With the 6S, it appears that you do need the Home to recover from the phone being disabled:
If you forgot your iPhone passcode - Apple Support
Therefore, your only option would be to have the Home button repaired:
Only you can decide if the cost of the repair is worth it for an old iPhone.
Good luck.
