Lumia 950 XL cannot get to mass sorage mode

I tried once WOA with my Lumia 950 XL but could not get the dual boot feature - windows phone and woa.
So I did a complete reset of to Windows Phone and tried to start deploying again.
At the step to unlock the boot loader I get the info: Phone is already unlocked.
At the step to switch to Mass Storage mode, the phone does a restart with a quick flash of a red screen an then boots again to windows normal mode.

What can I do now?
helpless, Wolfgang

Servus Strolchi,

I think you should reflash Windows Mobile, update it to the latest Firmware (e.g. via OTC Updater) and then do a new WoA deployment. I did that because the Phone App was inaccessible... Now it works.

Hope that helps...

Ciao,
Joachim
