UEFI stuck after using 'efibootmgr'

I have used the efibootmgr tool to add an arch boot entry to the BIOS/UEFI boot menu and now it does not boot to the UEFI settings nor to the system. Even though i have used this tool before and it had worked, this time it was different. I have tried everything, all available keystrokes, and nothing seems to work. It's just stuck on asus logo. The laptop motherboard is a X540UAR.

At first I ran the efibootmgr to add an entry pointing to zfsbootmenu, something like:

efibootmgr -c -d /dev/sda -p 1 -L "ZBM" -l '\EFI\ZBM\VMLINUZ.EFI'

then quickly ran reboot command, once it was rebooting I pressed F2 multiple times to enter the BIOS, then it came with a black screen (just LCD gray background) then I waited for about 5mins and no luck, seeing that I pressed power button to power it off and tried to open BIOS again by pressing F2, but now it's just stuck on logo, not even that black screen anymore.

Re: UEFI stuck after using 'efibootmgr'

Hi, have you tried doing a hardware reset (I think that's the name, were you cut the power for the bios settings memory to reset it)? Take a look at you MBs manual on how to.

I've just disassembled it and it does not have cmos battery nor CLRTC pins (that's all I found on Google that can hard reset bios settings)
