Phone can't boot into bootloader or recovery after trying to switch back to stock ROM

I was switching back to stock ROM from Resurrection Remix M on my ZE550ML because I wanted to update the firmware so that I can install Cyanogenmod 14.1. After I downloaded the firmware zip file from Asus, I copied the recovery.img, boot.img, and droidboot.img files. I rebooted my phone into the bootloader and flashed each file using fastboot flash. After this was done, I rebooted into recovery, but it never got to that point. Now my phone's stuck on the Asus Logo screen. I tried the key combination to boot into bootloader or recovery, but that didn't work. Neither adb nor fastboot can detect my phone. I don't know what to do. I looked at tons of posts, but nothing can help me. Any ideas that can help are appreciated. I'm in a pickle right now.

can anyone help me? phone is stuck!

okay so i tried to flash a cypher OS rom on my sultanxda CM13 and my phone is currently not going into recovery so basically i am stuck in fastbood mode . my device state is unlocked and when i restart or try to go into recovery the phone just turns off and does nothing. the only way i can actually turn the phone on is by holding volume up + power + home (hard reset tactic)
can anyone help me?
so where do i go from here? i tried the toolkit unlocked and re-locked the bootloader, tried to flash stock recovery img, tried to flashing twrp, nothing works guys.

flash Original Rom

Make sure you're using latest modified recovery (28) by eng.stk.
From your description the phone most probably doesn't actually turn off, it just displays black screen (common issue caused by TWRP incompatibility).

You re-locked the bootloader while you were still on a custom ROM and/or recovery?

HTC M9 BRICKED access to download and bootloader URGENT HELP PLEASE!

Hi,
I just flashed the rom deodexed developer nougat on my himauhl (Europe) in twrp 3.0.3 and it failed so I did another wipe and twrp crashed. It rebooted straight to the htc logo and was stuck there. When I reboot into twrp all i get is a glimpse of the twrp boot logo thing and then it just goes back to the green htc logo. I have tried flashing stock recovery.img and it boots into that and i dont know what to do. I have also flashed stock boot.img and it does nothing. I flash twrp again and it does the same thing. Please help. Sorry for being an idiot I am new to all these different varients. Also sorry that my spelling it off, I am panicking! : :crying:

Information that may help us help you:
Can you boot into anything? (recovery, bootloader, download - try powering off the device and powering on using PWR+VOLDWN)
What was your original SKU?
What was your OS version before you attempted to flash this latest time?

Hi,
Yes I can boot into bootloader and download but cant boot into twrp as I said but if I flash stock recovery I can boot into that. My os version was 4.14.401.7 so I think I know what the problem was. I didnt update the firmware . Sorry im new to all this. I decided to lock my bootloader and flash the stock rom and firmware and everything but for some reason, the bootloader wont relock. I send the command fastboot oem lock and it says OKAY but I boot back into bootloader and it says unlocked.
Please I need help!!!
Any ideas?
Thanks,
Jev

Zenfone 2 z00a stuck in fastboot mode, will not boot up

Ok guys please help. I got this phone today and after playing around trying to install Lineage 14.1, i am stuck in fastboot. Recovery mode will not open, it just goes back to fastboot. Same thing happens when I attempt to do a normal boot, or turn off and on again. The phone is not rooted, and I have reflashed the custom recovery after failing to install lineage. It was bootloader unlocked but I think that was undone when I flashed an update to the device. I don't need help with lineage installation, I've decided its not worth the hassle but please help me get my phone to boot. Thankyou.

Get the latest raw image and the asus flash tool. Use the tool to flash the raw image in fastboot. You'll be back to factory.

did you used the flashall bat file to install marshmallow firmware through fastboot??
or
installed system, boot and recovery files separately??
