Hi,
so Cmd-Alt-P-R should zap the NVRAM, Cmd-R should boot into recovery mode. When I press Cmd-Alt-P-R on my MacBook Pro, it asks me for my firmware password and then wrongly boots into recovery mode. How can I zap the NVRAM instead, as should happen?
Thanks
PS: All keys on the keyboard are working just fine.
MacBook Pro (Retina, 15-inch, Late 2013), OS X El Capitan (10.11.6)
Could be you aren't holding all the keys down simultaneously or long enough. Here is a way from the Terminal's command line: sudo nvram boot-args=”-p -r” or you can try instead, nvram -c. Do not know if either still works. Then you might try this:
Resetting the NVRAM on Late 2016 MacBook Pros and Later
MacBook Pro models introduced in late 2016 have a slightly different process for resetting the NVRAM to its default values. While you still hold down the usual four keys, you no longer have to wait for a second reboot or listen carefully to the startup chimes.

I've never used a firmware password. I suggest you might try disabling that for now. I'm guessing that the computer cannot be restarted without that password, hence, it is reverting to the Recovery HD. Or your disk drive has failed.
Thanks, I'll try the nvram command.
PS: I'm sure I'm pressing the buttons the right way, done it often and it always worked at the first or second attempt.
I've been thru the same thing. Don't know why it doesn't always work. Could be because of using the BlueTooth keyboard. I've never had a problem with a wired keyboard.
Oh, be sure you hold down the keys until the chime has been heard. No problem holding it more.
Thanks, but this is a MacBook Pro with the internal keyboard (that is otherwise working perfectly fine).
I'm holding the keys until the chime, and on until it asks for the firmware password, and then again after entering the password until it boots into recovery mode...
How to fix Cmd-Alt-P-R booting into recovery?
