Couldn't update ASUS ZenFone 2 laser 550kL
Facing the same problem
Baseband version - 202c10_10.0.0_160602
Build no. - WW_21.40.1220.1708.20160621
First I tried to update automatically through OTA update but failed.
Downloaded file from ASUS website (build no. 1877 ) and tried to do it manually by placing it in the root folder but still that failed.
ERROR - E: failed to mount / asdf ( invalid argument )
Please help with updation using simple method

flash stock recovery first if you want to do Gabbro16Hz method.

3gb ram varient of ze550kl has this kind of problem.
You need to download latest firmware from the asus' site. Place it in the sd card.
Enable usb debugging in developers' setting. Then boot your phone into fastboot mode. Connect phone to pc via cable.
Then put the tools.zip file in the pc and unzip it. Open that folder. Run 'flash all.bat' file. This will flash stock recivery to your phone.
Now boot phone into recovery mode. Select 'apply update from sd card. Select the firmware and flash. Then reboot. Work done. Your phone will have latest update.

[HELP]ASUS ZENFONE 2 LASER ZE500KL, No Fastboot, No Recovery, but can open the phone

Hello guys.
I have a zenfone 2 laser ze500kl. I downgraded my phone via twrp and install from MM to L version, but when I successfully installed the L version i cannot access to a fastboot mode or stock recovery. Only the asus logo displayed. I manage to remove the battery to restart and successfully gain access to my installed apps and used it but the fastboot mode is gone. Im afraid to type a command in cmd again because im afraid that it will bricked and I cant access to a fastboot mode or srock recovery.
Anyone can help me please. System veraion is WW_12.8.5.118

If you have the firmware of your MM stock from ASUS website, try to copy it in your external and internal sd card. Go to setting and check for update if something pop up about update, update it maybe it will install the MM ROM with fastboot and recovery. Try also to restart phone and check for update.
PsS. Why bother to downgrade when MM is better the L?

im just trying to root my phone, i read in the forum that it is tested to root asus ze500kl with L version.
i have a copy of both MM and L to my sd card. is it safe to update it via settings update?

I dont know but I think it is safe to update back to MM via update setting and maybe it will restore your fastboot and recovery. Because you encounter those problem while flashing back to L.
It is easy to root your once you have TWRP insalled, just flash Superuser or SuperSU zip and your stock ROM will be rooted.

Did you try rooting your asus ze500kl in MM veraion?
Im following a thread here. He said he successfully rooted his asus via cmd. "mod_boot.img" he share in the forum.

I dont have ze500kl, generally you can root your phone by flashing supersu or superuser zip.

Ah ok. Tnx for the help bro. Appreciate it

Asus zenfone 2ze500kl
I cant get into a recovery mode or fastboot mode by pressing the combination of keys. What can I do to get to recovery mode to be able to flash os? Now just Asus logo appears all the time and nothing happens.
Help please!

Downgrade to Marshmallow

Hello Friends, I just upgraded my Zenfone 3 ze520kl to Nougat, but i prefer Marshmallow i try from recovery mode to flash Marshmallow, it shows error and the installation aborted. Can any one help . Thanks.

What error does it show?

Error with some numbers follows by 'install aborted'. I unable remember the error numbers. I did three times all the time with same remark.Thanks.

That's not very helpful. Can you try it again and tell us exactly what it says?

Hi,
I downgraded a few days ago, here's an overview of the steps.
WARNING, this requires a factory reset so you will lose the data on the phone, so make sure you have backups before you proceed. You do this at your own risk and I am not responsible for any damages.
I assume you have adb / drivers all configured and know to how use them.
1) download firmware file http://dlcdnet.asus.com/pub/ASUS/ZenFone/ZE520KL/UL-ASUS_Z017D_1-WW-13.20.10.152-user.zip and save to SD card / insert card in phone.
2) download recovery and boot img files for Z017D_WW_13.20.10.152
- https://mega.nz/#F!ok0V0RIA!5WKtHe98opzjVI3NPbM7Ww
- under the folder Z017D_WW_13.20.10.152
3) Go to fastboot mode (power + vol up)
- flash recovery.img (command: fastboot flash recovery recovery.img)
- flash boot.img (command: fastboot flash boot boot.img)
4) reboot to recovery (power + vol down)
5) install update form micro sd card.
set the file UL-ASUS_Z017D_1-WW-13.20.10.152-user.zip that you saved earlier
6) wipe cache
7) factory reset
If you don't do a factory reset and reboot, Android pretty much crashes on multiple processes on start up, it is unusable.
Regards,
TK

Warning- No file-contexts. This package is for "ww-phone" devices, this is a E:error in /side load/ package.zip (status 7) Installation aborted.

Same thing happened to me as well. I just went ahead to flash the RAW file (http://www.asus-zenfone.com/2016/12/asus-zenfone-3-raw-firmware-and-asus.html) and updated the software to the latest marshmallow update, followed by a factory reset.

If we Downgrade
Then we get update in future yes or no??
Sorry for bad English??

Yes.

Hi, thanks for the help. Please answer this:
Do I need to use Recovery and Boot.img the same version of ROM? Why?
Why do I need to install Boot.img?

I need the original boot.img for the very first firmware on asus zenfone 3 520kl.

I have twrp flashed on my phone, and so cant get the oreo update. The phone had been stuck in the bootloop recently, and the guy at the service centre flashed the first available version of the firmware, but how he did it without removing the custom recovery, i dunno. So now i need the boot.img for this firmware: (WW_Phone-13.16.5.33). Thanks in advance.

It says the stock firmware is for nougat, i myself am currently running marshmallow. I had tried to flash nougat through the custom recovery, ( when the thing was stuck in a bootloop) and it said something like only versions upto *some serial no.* can be updated.
Anyway, thanks for the links, will try it.:good:

2) Go to fastboot mode (power + vol up)
- flash recovery.img (command: fastboot flash recovery recovery.img)
- flash boot.img (command: fastboot flash boot boot.img)
3) reboot to recovery (power + vol down)
4) install update form micro sd card. set the file UL-ASUS_Z017D_1-WW-13.16.5.33-user.zip that you saved earlier
