All of the links in the OP work for me. The Mediafire link you provided works as well.
[ZenFone 2 Android Development] BOSSPDA:
Yes, the mediafire link is ok, but I can't find any folder.

In last Sunday the folders Wfolders

I believe.

But when I'm inside the mediafire I can't find any folder, like in last Sunday when I downloaded the other files from WW_2.19.40.22 firmware.

I don't know, now, if I need to register and login in the mediafire site
[ZenFone 2 Android Development] ShadeXVII:
Maybe i'm a little slow on this but isn't there supposed to be the system file that is around 1-2 gigs?!?!

I see where the files have been broken down but how do i repack that into a system file?!!?

Probably need to upgrade your adb and fastboot.

In the command window type adb version, should be 1.0.32.

[ZenFone 2 Android Development] DJR96:
This is driving me up the wall!!!!

Just trying to update to the latest pre-rooted image. Everything downloaded and files combined (WinZIP) just fine. The four .img files moved into the platform-tools folder all set for fastboot loading. Phone entered into fastboot mode just fine. But I can't get my phone to show when entering the command "adb devices".

I had this trouble once before and it eventually decided to work, but I still don't understand what it is that's needed to make it work.

Any pointers?
[ZenFone 2 Android Development] fuzzybuffalo:
It's your drivers, if your on Linux or Mac, sorry I can't help.

If your on Windows, go into Device Manager, open Android Device, right click the yellow exclamation mark or what ever you have there, Update Driver Software, Browse my computer for driver software, then browse to where ever you extracted the Asus drivers and select them.
[ZenFone 2 Android Development] DJR96:
Hmmmmmm

OK, went to update driver software as per your suggestion. But I foolishly let it search. It downloaded something and installed it. Unplug USB and re-connect it and now nothing comes up at all in the device manager. Tried the 15-sec ADB installer (1.4.2) still not recognising even a connection to my phone now. Like I said, frustrating!!
[ZenFone 2 Android Development] fuzzybuffalo:
[MENTION=6498865]DJR96[/MENTION]

If you quote my post or put the @ sign in front of my name, it will get my attention.

Hmmmmm...

That is strange. Have you tried rebooting the comp, to see if the phone shows up then.

The only other thing I can think of is go into Control Panel, Software, and see if there is any Asus software or drivers you can uninstall.
[ZenFone 2 Android Development] DJR96:
[MENTION=5973725]fuzzybuffalo[/MENTION]

OK, I've completely un-installed any and all software/drivers to do with my phone off my PC.

At this point we'd expect, when connecting the phone, that it would ask for drivers to be able to do anything with the phone. However it popped up an explorer window and seemed to be navigable straight away. I even went to the platform-tools folder and ran the adb devices command and hey presto, up came my phones serial number!! Woohoo!

So I thought I'd restart the phone into fastboot mode and re-connect. Now the adb devices command doesn't find it. :(

I've run the 15-sec ADB installer and it has the Windows Driver package by Google installed in the Programs list.

In the Device Manager there is an entry for ASUS. The driver version # is 8.0.0.3 dated 16/3/2015.

But still no connection while phone is in fastboot mode.......

What am I still missing??

Thanks for your time too!!
[ZenFone 2 Android Development] fuzzybuffalo:
Your Welcome.

adb devices does not work in fastboot mode, use fastboot devices.
[ZenFone 2 Android Development] DJR96:
[MENTION=5973725]fuzzybuffalo[/MENTION]

Howabout that! It works! I knew it had to be something simple..... Never seen that anywhere. Would be a good point to add to the OP's instructions.

Thanks so much.
[ZenFone 2 Android Development] DJR96:
OK, so I finally got the hang of installing/updating via these pre-rooted ROM's. Many thanks to [MENTION=1813976]shakalaca[/MENTION] for providing them and to [MENTION=5973725]fuzzybuffalo[/MENTION] and others for your help.

Issue now is that a long awaited app has finally become available ( http://www.optus.com.au/shop/mobile/network/coverage/wi-fi-talk ), but a prerequisite is your phone can't be rooted!!!

So my questions are:-

Will doing a "Full unroot" in SuperSU satisfy the above?

Is it easily re-rooted via SuperSU, or do I have to do say the 1-click root method as if starting from completely stock?

Or is there some other technique that will make it appear to be non-rooted when it actually is?
[ZenFone 2 Android Development] fuzzybuffalo:
1. Yes, with a full unroot you will be completely stock.

2. Nope, have to use 1 click method.

3. I've heard of an app that will hide root, but can't remember the name. Have never used it.

And the only times I've seen it mentioned is when it did not work. sorry could not be more help on this.
[ZenFone 2 Android Development] DJR96:

[ZenFone 2 Android Development] maxlifan:
I have the exact same issue as you. It started happening after flashing .22 firmware. I was scared stiff when I softbricked my phone and couldn't flash anything using fast boot. I was lucky that for whatever odd reason I was able to recover thru flashing stock firmware.

I still can't flash any firmware in fast boot and my serial is now listed as 12345667890abcdef. Not sure how to fix. If someone can give some advice.
[ZenFone 2 Android Development] 27ylliw:
Maybe Shakalaca don't have time to make new pre-rooted image.

I've done by myself.

I've unrooted my 550ml from super-su options, after i've flashed the stock firmware 2.20.40.41 (you can download from asus support) using recovery mode (put the zip file into root of external sd card and rename zip file to MOFD_SDUPDATE.zip and reboot in recovery mode) .

After flashed the stock firmware without loss anthing, i've applied OTA until to get last firmware and after i've rooted again the phone using the click root tool method

Hey there.

Monthes ago I rooted my gf's Asus Zenfone 550ML using Z008 WW 2.15.40.13, flashing only system.img and updating SuperSU when asked.

I didn't flash boot.img, droidboot.img and recovery.img.

Since then, she's getting an error on every firmware update that arrives to the phone.

I guess I missed something but is there a way for having the firmware updating witout problems?

Thanks as usual!

Hello.

I had a full unroot via SuperSu for installing the firmware update, then rebooted and seen that SuperSu correctly disappeared.

But when I tried again the firmware update I got error again.

What can I do?

Thanks.
[ZenFone 2 Android Development] ddfault:
My steps involve you flashing full stock ROM from Asus and re-rooting your phone which is what I typically do.

Before you begin go ahead and place the latest UPDATE-SuperSU-vX.Xx.zip on the internal and external storage of your phone.

You will also need the temp root program you can get here (http://xdaforums.com/android/development/intel-android-devices-root-temp-cwm-t2975096)

Typically when there is a Stock firmware update, I proceed with the following:

Download the full file from ASUS,

Copy to microSD card.

Rename to MOFD_SDUPDATE.zip

Turn off phone.

Hold Power button + Volume up

When the phone is vibrating release power button

Use Volume Up and Down to get to the menu item entitled Recovery Mode and press the power button.

This will boot to the android recovery partition and start installing this MOFD_SDUPDATE.zip from the MicroSD card.

Press and hold the Power button. While pressing the power button, Press the volume Volume up. Release the volume Up button. Release the Power button. This will show you more than a logo.

Wait like 15-30 minutes for the flash to complete.

Pull down a copy of this to root zenfone using computer: http://xdaforums.com/android/development/intel-android-devices-root-temp-cwm-t2975096

When firmware finishes I use the volume up and down buttons to navigate the android recovery menu and reboot to bootloader so your phone is ready for the rooting process.

Extract IntelAndroid-FBRL-07-24-2015.7z

Plug your phone into your computer.

Run launcher.bat

Accept, choose your recovery option (CWM is classic, but only supports internal storage. I typically use twrp_hdpi_portrait.zip which supports internal and microSD card)

Select fastboot oem trigger used to launch recovery :

T4 is the option that supports our Zenfone 2.

It will detect your phone is already in bootloader and start its process.

When it finishes, you will have a temp copy of TWRP which will allow you to run the UPDATE-SuperSU-vX.Xx.zip that you already copied to the internal or external storage of the phone.

When you finish with TWRP you can reboot and you will be on the latest firmware, modem firmware, and again have root.

Because you flashed the full ROM, any ROOT apps you installed or modified hosts file, basically anything different about the SYSTEM partition from stock, will be lost. You will have to reinstall any root apps you may have been using. These are typically what hoses up an OTA update because these aren't taken into account with those differential updates.
[ZenFone 2 Android Development] ddfault:
I've pulled down the WW_2.14.40.19 update from the servers ~109MB and it looks like every file in the archive is a patch file. Maybe in a bit they will release this version as a download on the support.asus.com website. Also, the support.asus.com website is now showing a CN firmware available for download. No TW version yet. :(

[ZenFone 2 Android Development] a76vna:
I can access fastboot mode normaly but the recovery from fastboot mode is error now.
[ZenFone 2 Android Development] lordpipa:
I understand but when you choose recovery, it'll boot ya to Asus splash screen first, when it happens star pressing volume up and power at the same time.
[ZenFone 2 Android Development] ddfault:
Yes, Recovery is stupid annoying to get into. Start with phone off and unplugged.

Press Volume Up + Power, When phone vibrates, let go of power but keep holding Volume Up.

When you see fastboot, let go of Volume Up.

When You see the big menu at the top, use volume up or down to navigate to recovery

Press Power Button to enter recovery.

Wait, it will state, updating (or something like that)

You will get the dead android buy with an error eventually.

At this point press Volume Up + Power Button and let go.

At this point I keep trying the Volume Up + Power button, over and over and I vary how long I hold them down for. EVENTUALLY, I am successful and I get to recovery.

Recovery works the same way as fastboot. Volume Up and Volume Down go up and down the menu while the Power Button is Enter.

I have uploaded the WW_2.14.40.19 delta. The file was originally named "dlpkgfile" without quotes and I found it under /cache

The full path and filename should be /cache/dlpkgfile

ZE551ML_WW_V2.14.40.19.dlpkgfile

MD5: 42ba5bd3893c5d7c9c75208c0ca51720

SHA1: 7f5a4a9f42904ef64164f6097bede68af829b8a7

You can download it here: ZE551ML_WW_V2.14.40.19.dlpkgfile
[ZenFone 2 Android Development] sorg:
Thanks for update package!

You don't need to press volume and power buttons randomly. To pass that error screen, simply press and hold Power button, then (while holding power button) quickly press Volume Up and release. An then release power button.
[ZenFone 2 Android Development] a76vna:
Thank you so much. I can access Recovery by keep Volume up and Power 3 times.

OTA Survival with Supersu Pro

Has anybody tried with Supersu Pro to see if root would survive an OTA? Is there any obvious technical reason why this couldn't work? I don't totally understand how the root survival feature works, so I'm not sure if there is any chance it would work in our case.
[ZenFone 2 Android Development] Allesa:
can we use the dlpkgfile to update our firmware manually without ota? if so, how?
[ZenFone 2 Android Development] lordpipa:
I think if u rename it to update.zip it might work.

Sent from my Nexus 7
[ZenFone 2 Android Development] sorg:
There are 2 possible way:

First way:

Rename it to UL-Z00A-WW-2.14.40.19-user.zip and upload it to root of internal storage (not sd card!). Then after unplugging USB cable, phone should recognize update.

Second way:

Rename it to MOFD_SDUPDATE.ZIP and upload it to root of SD Card. Reboot into recovery mode and it will be installed automatically.

Make sure you are on FW v2.13.40.13, otherwise it will be failed or will produce strange result.
[ZenFone 2 Android Development] Allesa:
but first, i have to unroot via supersu right?
[ZenFone 2 Android Development] Allesa:
I tried the second way and it produced an error. Tried the first one, it shows installing system update however it stucks at around 30 percent. I waited for an hour but nothing. When i restart the phone, everytime it goes to that same installing system update. Tried to reflash system.img via fastboot, but after restarting i still go to the same installing system update. Any suggestion on how to reflash a clean stock rom via fastboot? Because i can only go there.
[ZenFone 2 Android Development] a76vna:
I think you need reflash your phone via adb. firstly you must download the original FW from Asus then enter recovery and flash it by command: adb sideload file.zip

good luck
[ZenFone 2 Android Development] Allesa:
Cant go to recovery, only fastboot mode. Whenever i tried to go to recovery, it goes back installing system update again. Is it because i have the update file on internal storage? so it automatically search and try updating my phone ? Is it possible to flash the original FW from fastboot command?
[ZenFone 2 Android Development] solquest3:
Wow, thanks a lot for the detailed guide!!

But re-rooting the phone does this mean that I'll have to do the same thing if I get another update at some point?

I mean, I actually don't need the phone to be rooted anymore (it's gf phone and rooting was only for uninstalling unuseful apps and moving apps to sd card), so I could also leave it unrooted, if this make easier installing next updates.

Cheers
