He's rooted. I'm not sure about the bootloader but I am sure that he's modified the system and therefore can't update. Has happened to me before.

Extract this "NC" file and copy it to your phone's storage.
Now u need to flash a twrp recovery. when you did,Open twrp and go to "Mounts" and activate "System"
Then go to twrp's file manager and move "NC" file to this path: "/system/xbin".
Now flash your stock recovery and try to update again.
It worked for me
(THIS ERROR HAS NOTHING TO DO WITH UNLOCKED BOOTLOADER)

By the way you have to Unroot your device first if it's rooted

Lollipop Update problem Solved
Hello ,I have the problem of updating lollipop over ota update. The problem got solved by the following Step by Step procedure.
1. Unroot the device . Go to the supersu on the App menu and then go to Supersu settings and select unroot.
2.Reboot the device in fastboot mode (Press power + Volume Down together).
3.On hboot menu Select Fastboot. Then Plug your device with Pc .
4.Download the fastboot.rar from Attachments. Extract the Fastboot.rar file on pc. Open the Extracted Folder.
5.On the Folder Press SHIFT+Right button of the mouse. Select Open command window here.
6.Type " fastboot flash recovery recovery.img " (Stock recovery is attached on the fastboot folder)
7.Disconnect the usb from pc. Reboot the device.
8.After the device getting started go to device update and download the update and Install this.
This is the procedure to get Ota Lollipop Update.
If there is a problem then install twrp,root the device and then unroot again and follow this procedure.
Thanks

You cant sideload a zip file. You need to sideload the pre-rooted image then update to go back to stock...

My Asus zenfone 2 ze551mi was on CN firmware before . I decided to flash the pre-rooted system img on this website and ended up with WW firmware , i followed the instructions by downloading the OTA and then i put it in the root of the phone storage , but it starts update and end up with an error. i just want to have a non rooted and stock ww firmware on the device . is there a way out?

I also have a CN version flashed to WW.
I erased the boot image, recovery and system images using ADB then replaced them with WW version. I installed the pre-root img. for the sysem then updated. Once you update it will remove root for you, unless you find the latest pre-root files and ADB sideload that.
I believe the latest WW firmware is 2.15.40.13...

zenfone 2 flashing
i have this problem too. may i know how to flash the firmware? anyone know?

Have you tried an alternative method of "firmware flashing" using a MicroSD card?

I know this is a long past due thread never seeing a presentable solution and possibly not even needing one anymore, but I came across it and thought I might add to it if I can, in the event that it's found by someone else having a similar issue.
Rather than attempting to flash using adb/fastboot or using the command window or placing the update in the internal storage of the device for that matter; to apply the update try using this alternative method:
First rename the firmware zip file to the following:
MOFD_SDUPDATE.zip - No need for version numbers, world codes, region codes, etc.
Then, load the newly renamed .zip file onto a microSD card (again, not internal memory, but external) and then boot the Zenfone the same way you would when trying to get into recovery. The system should automatically recognize the .zip and on it's own, begin applying the update WITHOUTthe need of being connected to a computer. It's, in a way that's oversimplified and not to be taken literally, essentially tricking the system into thinking it's an OEM applied update and allows extraction and execution/flashing of the zip file more freely then say, through fastboot without properly set permissions and needing to be a .img file specified to a partition table address.
Hope this helps or somehow makes its way back a couple of years to the you who needed it xD If it doesn't, then simply DON'T hit the Thanks button and let me know what happens instead and I'll try to better assist you.

Strictly follow these instructions!
A method for producing a flow 5.0.2 5.0.2 with subsequent update to 6 mm 100% process working. install stock rekaveri , If you have unlocked bootloader , relock it, рut it on your external sd card not decompress zip archives(0PFJIMG.zip), boot into bootloader with volume - and power button. it will read the zip, and if it compatibel with your os it will aupgrade and you have to confirm with your buttons.

thank you for your reply.......but i have to put both files in my external sd or what? Can you give me more instruction to follow .......thank you

No, you only have to put the 0PFJIMG.zip to your external SD. Then it will give you an alert called: "Do you want to start update" or something others, you have to press the volume up button and then it's updating. But make sure you have stock recovery and locked bootloader, otherwise it will not work.

I read your post above. You don't need to install stock recovery because your device has already stock recovery due to locked bootloader and S-ON. Just put the file in root of ext sd and boot to hboot. It will ask to update. So press volume up to update. If it doesn't work after all the posts in xda, then you can contact HTC to fix that problem. Maybe they can find a fix for it or it is an known bug.

[HELP] Can't flash Stock 7.0Nougat via Stock Recovery...

I got a ZF3 Deluxe from Italy, is TIM branded, and stuck on MM 6.0, no updated released for this brand, so a friend of mine told me there is of course android 7 for ZF3Deluxe, so i wanted to manually upgrade system to 7.0 Nougat, i downloaded the Stock ROM from asus (2.15ghz cpu, i've checked of course) but when i try to flash it from the Stock Recovery i get this error (see the attachment) i also attach the software informations, (looking at the error i receive it may see the archive is corrupted, but i've tried to download it from Asus many and many times)

You have a carrier rom on your phone and the international version fails the upgrade check.
If you could get your bootloader unlocked that would be a way around it but you need to upgrade to a certain rom version to do that and the carrier hasn't supplied that rom...
You're essentially screwed until the carrier either releases the bootloader unlockable rom or upgrades the rom to nougat...

You should try to flash stock recovery of WW in fastboot.
And then flash 6.0 WW rom by WW recovery.
Even though ,I didn't sure that if it will work(because I don't have Z016S),but you can try it.

Install : ADB & Minimal Fastboot.
Install : pyton 3.6 https://www.python.org/downloads/
Download the latest WW-4.12.40.1698 (For 2.15GHz CPU or 2.40GHz CPU) from Asus WebSite.
Download "Dat to img by stupdroid.com" (search it with google).
Extract Dat to img by stupdroid.com in a Folder.
Open the Firmware ZIP and copy system.new.dat, system.transfer.list e file_contexts in the Dat2IMG's folder.
Execute system.new.dat 2 flashable img converter.exe and just press ENTER and wait till the end of procedure, you will receive 2 files : system.raw.img e system.new.img.
Copy system.new.img in your Fastboot's folder.
Put the Phone into Fastboot mode.
Open fastboot and put this command: " fastboot flash system system_new.img "

I forgot to say, after this procedure, just flash the stock WW recovery via Fastboot, then download from asus the lastest 7.0 firmware SKU WW, all perfect. tested by me.

Ok I already have system.new.img, I copied it to the root folder of the SD. Device restart in Fastboot mode (power + vol.up key). Exit screen with message Fastboot mode and does nothing.
Install in the computer the pyton 3.6, I suppose that it serves for the process of generating system.new.img.
I do not know how to do the first step "Install: ADB & Minimal Fastboot.".
Thank you and forgive my translator

Try this
or try flash ZenFone 3 Deluxe ZS570KL_WW stock recovery of 4.12.40.1698 and flash UL-Z016-WW-4.12.40.1698-user.zip in recovery (by micro sd or adb sideload)not sure if it work(need verification,I wish you to try first).

Please help me, my model is the Z016S
I can convert UL-Z016-WW-4.12.40.1698-user.zip img and flash with fastboot.
Reboot and it works, but I do not know how to get into recovery.
I have also installed the Z016-WW-4.11.40.1085_recovery.img. The TIM DISAPPEARED
Then I copied the UL-Z016-WW-5.14.44.1898-user.zip into the internal memory and it does not install well.
I have proven the same with UL-Z016-WW-5.14.44.1898-user.zip and it does not work me it stays in a non-comands and will not boot.
greetings and thanks
P.S. At least you do not see the TIM anywhere.

So,what is your system version right now?4.12.40.1698?

I have done this and it installs,
fastboot flash recovery Z016-WW-4.12.40.1698_recovery.img
reboot, boot system, detect update file is installed, reboot and then gives error (3) unknown.

Tow solution you can try
1.install the rom of 4.12.40.1698 again(some of tile,such as xbl,devcfg,devcfgbak..... may be still TIM versio.install it in recovery may turn it into WW version)
2.If fail, try flash these files in fastboot.(I will upload these files for you to flash,also you can draw by yourself)

Ok already worked, the solution is to unlock as you put in # 11.
Thank you
