Yeah. It would be really great if you help me out with
it.
What is that
If you want to flash a custom rom, you don't need to unlock bootloader for it.
You can flash custom recovery using fastboot mode, after which you can install custom roms.

I did the same method as you are telling. I was able to install twrp through fastboot successfully(without unlock the bootloader) and installed custom rom and gapps successfully too. But when I reboot my device after installation I stuck in boot logo every time. I waited more than 30mins but nothing happened. No matter which rom I tried but I had to face the same problem ?. I don't know how to get rid of this issue.
And also my twrp showing an error which is -failed to mount/factory (invalid argument).
I think this is the reason why I'm facing bootloop.

I also unlocked mine using the same method that you have used. And successfully unlocked my bootloader. Then I installed twrp using fastboot. But my twrp showing an error which is -failed to mount/factory (invalid argument).
Then I successfully installed custom rom and gapps ( I wiped cache after installation) but when I reboot my phone I stuck in boot logo. I waited more than 30mins but nothing happened.
I tried so many roms but had to face same problem.
Is the twrp errors the reason of my bootloop issue??

Refer to this asus zentalk link.
flash twrp again and make sure to keep your volume down button pressed before entering the "FASTBOOT REBOOT" command.
Clear ur data after flashing twrp, flash trustzone fix also if you're getting error 7, install ur desired custom rom. It should work!!
I did the same a couple of days ago, it worked for me.

To install ROM you need a unlocked bootloader , screw twrp for now.

I'm currently on lollipop stock firmware with phone rooted and bootloader unlocked. I have also flashed latest Twrp recovey.
But here is the problem, i downloaded Resurrection remix latest version and tried to flash it, but error 7 came up. I bypassed this error by editing the updater script ( i followed a tutorial ). Now when i flashed the rom it says its sucessful but when I select boot to system it goes to fastboot mode. Im a noob so please dont be harsh to me.
PLEASE HELP ME FAST
THANKS

No, but to be sure go to fastboot the type:
fastboot oem device-info
if you see this -->> (bootloader)Device unlocked: true
then you are still unlocked.

Thanks man it worked and i am able to flash Resurection remix.
Thanks a lot again
Glad I was able to help. Warning, flashing can be addictive! And make sure to have a nandroid back-up.
WRT the original post, I tried the same procedure but after having errors i flashed the twrp with adb through cmd:fastboot flash boot boot.img . And now it is showing no OS available and shows that it is not rooted in the twrp recovery. Now it is still not flashing the rom and showing error and now i have no idea what to do. So, please give me instructions on how to repair my asus zenfone 2 laser ze550kl. I did all this on MM.
If you have TWRP 3025 then you can flash any custom ROM. Try to redownload the ROM, maybe it's just a bad download. What error did you see?
After a failed root I've recieved the error ' Can't load invalid boot image ' . I tried booting ' boot.img ' . That didn't work . After I tried booting it I got to the ' Asus , In Search Of Incredible ' waiting screen . After that , nothing else happened , and it kept loading . Will it load eventually or is it not working ?
Did you root by flashing SuperSU with the latest twrp?

I attempted to root it using this : https://forum.xda-developers.com/ze...guide-marshmallow-root-guide-ze500kl-t3380461
Try to flash the latest twrp3025 image found on this forum in fastboot mode, if you follow the steps correctly, your're bootloader should be unlocked. Then try to boot in twrp/recovery and flash any custom ROM, 13/14 based.
Edit: Can you access stock recovery?
Can you flash TWRP without your device rooted ?

I doubt I can acces that .
You can flash twrp as long as your bootloader is unlocked. Go tk fastboot and type
fastboot oem device-info
If you see "Device unlocked: true" it means bootloader is unlocked!
I'll try and unlock it now
I unlocked it . What now ?
After unlocking it , the error disappeared , but I'm still stuck in the Asus logo loading screen
Flash the latest twrp, custom ROM and GApps.
---------- Post added at 20:11 ---------- Previous post was at 20:05 ----------
I think you dont have a ROM installed that's why its stuck in asus logo. So you need to flash a ROM
I am downloading the latest firmware ATM and I am going to flash it . What is GApps tho ?
If you want to flash stock ROM(from asus website) you wont need GApps. You need to be in fastboot if you want to flash stock ROM, but I can't help you since I never revert to stock before. But there are many guides here for flashing stock, be sure to read the OP Thread and the comments for more info.
The ' Android is Starting ' thing popped up and I'm freaking out that it might work finnaly ..
It worked ! Thanks alot dude !
Congrats in bringing your phone back to life. Haha

Hello mates!
Yesterday I accidentally bricked my phone and I spent ours and ours on this and others forums to find solution but without succes, so here is what was happen:
I was on L21C432B380 firmware, stock, bootloader locked, without root acces. So I tried to flash ROM 7.1.2 AOSP by Meticulus. I followed step by step guide. I succesfully unlocked bootloader using fastboot. Then I flashed TWRP again using fastboot so I can downgrade to EMUI 4.X and that was succesfull also. After that I flashed oem-info using TWRP and flashed stock UPDATE.ZIP using three button method, both succesfully but when phone tried to boots up It shows message "No OS installed".
My entire system and data was deleted, there is no recovery, bootloader is again locked, I have only managed to get into fastboot mode using adb
Every single command I tryed to run in cmd results in this message: "FAILED (remote: Command not allowed)
Somehow I need to install Firmware using fastboot but don't know how cause bootloader is again locked
My knowledge about this things is above average but I cannot "google" the problem
Please help and thanks in adavnce

Hello man,
Dont know why u do that (downgrade to MM)...
Explicitly written for flash AOSP 7.1.2 to be on emui5 (were u was)...
Flashing oem also relocked your bootloader (written ton of times in threads)....
Now using fastboot re-unlock bootloader re-flash TWRP.
If u maked a full backup just use it, otherwise try to follow this guide..

so your bootloader was looked when you tried to "update" rom?
if so thats your issue. you can try to connect to pc and put phone in fastboot mode and unlock bootloader.

No they cant. Fastboot oem unlock only works with the T-mobile variant (unlock works without a key but is missing flash commands) and the us unlocked us996 can unlock by flashing a key from lg but can actually flash roms.
@uccfar is using the term rom when meaning stock firmware, and if this didnt happen when rooted or trying to root it could easily be a hardware issue.
