I recently upgraded my phone to OFFICIAL marshmallow update that Asus provided. Upon doing so my phone's bootloader got magically locked again and when I tried to flash custom TWRP recovery via fastboot the recovery got corrupt. I tried unlocking bootloader again with the software but it isn't supported cause It's marshmallow. The recovery can't be recovered to stock version either. What do I do? I can only access fastboot and nothing else.

Im trying to but my pc doesnt detect the phone so i cant flash anything through sdk
If your phone is in bootloader when you do fastboot devices, then the fault is likely with your windows drivers. Find the unknown or non working device in device manager and update driver to the Google drivers.

Custom ROM's are written from the recovery partition, but the recovery has no acces to the boot partition. If you're comming from an older version of android, which is likely when you're trying to install CM11 from stock, you will also need to update your kernel in the boot partition. Kernels are flashed using fastboot. make sure your drivers are up to date like mentioned above and extract the boot.img from the CM11 zip. load into fastboot mode and flash the boot.img. Your phone should boot after this.
In its current state, your phone is trying to boot a KK ROM on a JB kernel, which is why it's stuck in a boot screen.
Tried to unlock my bootloader with official method and i perform all my steps correctly after that i got stuck in booloop that time i tried to boot in recovery but fail my device dont boot in recovery mod after that i flash stock 4.3 firmware on my xpetria using flashtool n i started my device (everything wiped)
then again i tried to boot in recovery but fail i again tried to unlock it but again stuck in bootloader and again flash stock rom
please help me developers where am i mistaken my device bootloader unlock status is yes
and i have lost my drm key too
Are you trying to access Fastboot mode or the actual recovery? Because the stock ROM doesn't contain accessible recovery, which is why you have to flash a custom recovery separately.
History : i've been using an earlier pre-rooted rom for this device and after having taking care of unrooting it, i tried the OTA Update to upgrade and access the TWSP and Garbage rom.
My issue is that as i access the phone in fastboot mode with fastboot and adb i can't acces the recovery mode : the phone reboot to fastboot.
Any hint appreciated

According to http://forum.xda-developers.com/zenfone2/general/congrats-to-bootlocker-unlocked-t3138547
Step 1 to unlock is Update to 2.19.40
I'm on 2.15.40.13 and the OTA fails at the fastboot menu
http://forum.xda-developers.com/zenfone2/orig-development/rom-pre-root-img-t3079590/page51
I forgot this was a pre-root system.img file as explained, no stock system.img provided
I think the recovery limitation was made on purpose to avoid bootloop after OTA.
Looking for stock rom to flash via fastboot
Fixed :
Used cai_dat_CWM Tethered to flash stock rom from Asus Website
UL-Z00A-WW-2.19.40.18-user.zip from Asus Website
Then again to root with SuperSU246 update from zip

so did you lock the bootloader again? if you didnt do that the bootloader is still fine.
if you were bootlooping, how did you wipe all data i.e. how did you wipe the OS?
I restored the newest stock Android One ROM using MiFlash, but the phone only boots if the bootloader is unlocked. I need the bootloader to be locked for various apps. Can someone help me
I haven't found any threads that talk about this issue so I have no idea of what to do
Regarding your signature, I believe you have Magisk installed ? If you have Magisk or TWRP installed or if you've changed anything in the system, you can not lock the bootloader, as it will prevent the device from booting. All the partitions of the device should be stock and you should not have root, in order to lock the bootloader. My advice is to flash the stock rom via MiFlash again, but choose 'Clean All and Lock' option while flashing.
Install stock 10.0.13 version with edl mode:
fastboot oem edl , and flash with miflash,then reboot the system in fastboot mode to lock bootloader with : fastboot lock oem , then boot the system and update your device with ota.
