No mate, you will need to get OEM unlock enabled to flash anything other than a factory ota update. Search pixel bootloop and hopefully you'll find a solution to your issue.
Good luck

If you haven't tried it at all then first try to do a factory reset from recovery. If that doesn't work and if you're on stock and have stock recovery. Download ota: https://developers.google.com/android/ota and see if you can push it to phone using fastboot if you can't access storage of course. And then apply update in recovery. You should be able to boot then.

Tried with different drivers pdaNet method as well but no success.
Can someone guide me how to unlock the bootloader ? Want to install a good custom rom in my phone.
Update:
I have managed to boot into fast boot mode now adb is recogaizig the phone and fastboot as well but, when I use fasboot oem unlock it does not work.
online tutorials says I should find OEM Unlock option in developer options to make fastboot oem unlock work but there is no such option in developer options.
Hi!Yes,I'm late,but want to say that we can't unlock bootloader on this device. Company"Meizu" don't give this opportunity. Many users from other forums have tried to unlock,but all attempts have failed. OEM Unlock option is absent.

Help unlocking Bootloader for flashing stock Rom

So I had actually posted about this phone already but I wanted to get a seoerate discussion on unlocking
I am currently trying to flash a stock Rom to an Asus ZenFone 5Q ZC600KL X017DA with a Qualcomm chipset
The issue with the phone is that it's stuck on the logo when turning on it will say powered by Android then goto Asus then stops there
Factory reset is out of the question as the hardware keys only bring me to CSC fastboot mode
Now here is my problem the bootloader is locked and when running device info command in fastboot on laptop it will say something along the lines device unlock false same for unlock critical false
To unlock the boot loader everywhere is telling me I need to enable the slider for OEM unlock in developer and also enable USB debugging and Asus has an unlock tool but it's an apk file
Now as phone is stuck on logo when turning on I obviously cannot enable the OEM unlock it even enable USB debugging
So my goal right now before I proceed with flashing stock Rom is to get the bootloader unlocked
Is there any way to do this any software I can download with instructions or any options to unlock the bootloader via EDL mode
Is there an option to wipe out the bootloader and reinstall it from a firmware
Or is there something like TWRP that I can flash over to the phone under EDL that will give me options to unlock
Thanka
