Did you all try to reset NVRAM? Doing so fixed the problem for me.

Yes that was my first reaction but without success ... I'm still stuck with a black screen at startup, I don't know how to recover my macbook at this point, any help would be much appreciated :)

No access to clover menu also ...

Did you try removing battery cable and AC power? If you feel comfortable opening up the MacBook (model dependent and warranty considerations) if it's an older model like mine it's easy. I've frozen my MacBook a few times and do this to recover. I run everything from Mavericks to High Sierra on mine.

If you can get it apart and do that, also remove the ram and reset by hitting power button with no battery or AC connected.

Ps : my RAM cannot by removed, so I just tried to remove the battery power cable

FIY :
I had a long discussion with a senior apple expert about that on the apple repair center online,
I explained my situation in detail.

He is surprised that verbose mode and online mode won't work, because they are the first to be called, even when the classical EFI boot is corrupted.

So he would not be surprised if I had a hardware problem anyway ...
which would be consistent with your kind returns as NVRAM reset is not working for me.

Still, he declared that apple cannot reprogram EFI at all ...

So I have only two option left :
1) logic board replacement with certified apple store repair center
2) EFI chip reprogramming with a dump of an official firmware

I think I will go for the second option as I have nothing to loose

Unfortunately i trashed my mac mini also...Installed a new ssd after i cloned it in an usb dock with carbon cloner .After that i got a question mark instead of booting into macos..I had at hand a usb drive made for my hackintosh so i just booted into the setup just to see if the drive was recognized in disk utility ...After this i just rebooted...and that was it..mac mini bricked...black screen and the chimes running continuously. Took it apart, took every part from the motherboard including the battery...nothing worked. I took it to a shop but they said it`s the motherboard. I just ordered now from ebay a new bios efi chip. Hope it will work. I will get back to you guys when i have an update. But cannot believe that mac`s are so f*** dumb and the bios gets corrupted just by booting an usb..and without the possibility of rewriting or something like that.

After cloning a disk you need to add the Apple EFI folder to the drive. Its the same as adding clover to your EFI . I make a copy using carbon copy cloner then mount EFi and copy my Apple EFi partition folder to the new disk. The pic below shows a folder I created to remove and store my clover and boot folders from a working mackintosh drive so I could boot it on my MacBook. The Apple folder stays and it boots right up.

I am having the exact same problem, my wifi isn't the best so i wanted to install OSX from my external (hackintosh) SSD, when trying to do so i also screwed my EFI partition up. (atleast i think so.) it doesn't wanna turn on anymore, a black (although backlit) screen shows, apple logo lights up and the Force Touch trackpad works, Caps lock doesn't though. i tried all the normal boot up modes i could find on the internet and none worked... it's unbelievable that a external HD can **** your $2100,00 macbook pro up in a hitch with no way of turning it back. i went to my local apple store and it's being repaired as i'm typing this. problem is they are installing a whole new logic board, and it most likely won't be cheap. (i'm getting a receipt in 1~3 weeks) but because my display got replaced the day before this happend there is a chance they will fix it for free because i told apple that. (i'm out of normal warranty by the way.)

BUT!!!

if someone knows a easy (definite and not too expensive) fix to my problem, be free to share it with me, because when i get the receipt i have the chance to decline it if it's too expensive for my liking!

I accidentally installed clover on my Macbook Pro as well.. I didnt noticed that I was installing it to my SSD instead of the USB drive. My computer would boot straight into to clover when I would turn it on. I deleted the clover folder from EFI partition but nothing would happen on reboot and clover remained. The following day after trying to wake my macbook from sleep it would not restart, everytime the screen wouldnt even light up and there would be no chime, I rested the SMC which was the only thing that "worked", after that the screen would turn on (black screen) but the chiming would loop repeatedly. I took it to an apple certified place and they told me the only thing they could do is replace the logic board for $700.... Any help would be nice...
