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!

How to unbrick ZC520TL MTK6737M X008D Nougat, can't access recovery, fastboot

I mistakenly flash the wrong recovery image (twrp, then back to stock when twrp did not work) using fastboot. Just gave up on flashing the recovery and after a few months, I need to factory reset my phone and forgot that my recovery is corrupted or not working. After resetting and my phone rebooted, it just bootloop in the asus logo.
tried entering fastboot and recovery mode but it is no longer working.
So I googled and read that the only way to unbrick my phone is flash it with SP Flash tool. Can you help me find the correct firmware for my device? Or maybe i just need the stock recovery.img and flash it with SP flash tool with the correct scatter file.
My device is running the latest firmware when it was bricked.
Please help. Thanks.
Flash this Rom. It will unbrick your phone and back to 6.0. You'll need to update your firmware again manually.

Thanks, already restored my phone by flashing it with SP Flash tool and updating it manually with the official firmware.
Thanks for the information and ROM provided using SP Flash. I am now back at 6.0. What tools/firmware is required to update it manually to the latest 7.0 version? Tapping Settings -> System -> Check for Updates does not appear to do anything.
Hi, i've got a Zenfone 3 Max ZC520 bricked (it stucks on ASUS logo after i tried to install the SuperSU), when trying to install this firmware it shows me ERROR: S_BROM_DOWNLOAD_DA_FAIL (2004).
How can I unbrick it?
Thank you.
