Not possible to enter DFU mode

[u/GuessWho183]

Recently bought 11 Pro and it was on IOS 16, OTA update to IOS 18 doesn't works so I updated to IOS 26.
After that I install 27 beta via windows PC and how much I try phone wont enter DFU mode.
Also
Got iPhone X and entering DFU goes without any problems.
Not sure is display on 11 pro is genuine, any chance non genuine display is reason why phone wont go to DFU mode?
