Zenfone 2 ver 2.17.40.12 bootloops after flashing Wrong TWRP

TWRP recovery request fastboot command
I tried to flash twrp.img on my Zenfone 2 ver 2.17.40.12 (rooted). I guess there was a version mismatch, because I ended up with the screen saying "Fastboot cmd waiting". I am allowed to power down and normal boot, which work, but options "recovery mode" and "restart bootloader" return me back to the same screen saying Fastboot cmd waiting.
I tried to do a factory reset, but I got the same screen and nothing else. I downloaded ZIP file with the correctoriginal recovery for my version and tried to use fastboot command update, but it failed with message saying that archive does not contain android-info.txt and neither android-product.txt.
I will appreciate your advice to resolve my problem.
Well, fastboot is showing error because you're trying to flash ZIP file for the recovery mode(like TWRP) that doesn't have compatibility with fastboot mode.
You have to flash the .img file for your zenfone2(Z00A or Z008) with the command below.
Code:
fastboot flash recovery twrp.img
And also, model number(Z00A or Z008) is shown on the screen when booting in fastboot mode.

Rename ur boot image file to twrp.img
And then in adb type
1. fastboot devices (see if you are connected or not... If connected type 2nd command)
2. fastboot flash recovery twrp.img
After that by using power up button navigate to RECOVERY MOD and press power key
DONE
U will be running twrp recovery
flash magisk via recovery to maintain root
Enjoy
