iPhone 6 Plus can’t get out of recovery mode.

iPhone 6 Plus (model:A1524)

Following a change of battery the phone will not start.

Put into Recovery mode but does not show as a device in iTunes when connected to laptop using lightningUSB cable.

Can’t get phone out of recovery mode.

Have tried holding power+home buttons until see Apple logo. But returns to recovery screen.

Any thoughts or suggestions appreciated.
