Hey Xda,
Today I present you a guide on how to
REVERT TO STOCK OR REFLASH
firmware on the Asus Zenfone 2 Laser ZE5550KL.


This guide is applicable to both types of users ie who use TWRP and who don't use TWRP.After following this guide your phone will also be unrooted.


For TWRP Users

Here I give you links to two firmwares which you can directly flash via TWRP recovery.

Version:1.13.40.496
Link

Version:1.17.40.1234
Link

For Stock/Non-TWRP Users

The procedure is a little long here ==>
1. Download the official firmware from asus website.
2. Copy the firmware to the Micro-SD and rename the file (firmware) by one more(version).This renaming should be according to your current firmware version.If you have 17.something firmware and you download 16.something firmware then rename the 16.x.x file to some thing like 17.x.x For eg. if you have 1.17.40.763 then rename 16.x.x file to 1.17.40.764.
3. Reboot the phone.Android should automatically find the update file and offer to automatically update the software.Do it !!
4. Go to stock Recovery and wipe cache , dalvik cache and data.
5. Reboot device. Your phone will now be unrooted(if it was rooted before).


DONT FORGET TO PRESS THE THANKS BUTTON IF I HELPED YOU.

Before going back to stock and re-rooting to see if the issue was still present, I thought I'd ask if this is something to worry about ? I have the ZE551KL (Z00T) and have been flashing for this device with no problems whatsoever. What is it that I did while unlocking , rooting, and flashing twrp that may explain why the build number and device model don't match? Additionally, at times my PC will recognize my device as a MotoG when my device is connected to the PC via USB . I don't have access to my PC right now so I can't say this with certainty, but I think my PC recognises my device as a MotoG only when the device is in TWRP.. Maybe that means something was done wrong while unlocking the bootloader?

Lemme guess. You use that stupid custom kernel? That'd explain why About Phone says it's Z00LD.
