If you have english language set, search in settings "power menu" and switch on Restart menu
(or try with the word "menu" translate in your languange to find that setting page)
Then you can restart to recovery from the power menu
(I'm not sure if you need to have developer options active or not, I have it active)
I had activated, but the recovery bootloop and the mobile continue to the OS and doesn't enter to the recovery.
