Hey dude. First, welcome to XDA :)
Did u try the instructions exactly? And did u check the GP code and remove the extra 0?
And also, are you sure that you have installed the driver correctly?
And what windows did you use?

My point is this is not my frist time to unbrick my phone I know how to unbrick... and no problem to do at first time but after I went to Lineage OS then xfstk can't help us anymore.
As many time I try to unbrick but struck at
Continuing to Os...
reconnecting to device - attempt #1
Until
reconnecting to device - attempt #20
As I looking at the process our phone disconnect before 100% Moorefield disappear and it's doesn't reboot to 4Colour stripe

then .... Do you know what I have done?
1) I try both of 0×80000807 or 0×800000807 It's nothing relate to our problem. I always check that I flash with 4zero not 5
2) Battery ... I had 2 Zenfone2(Yeah I had 2 Device both of them = ZE550ML) and also change battery from another one I sure it's has 100% Power
3) Try with both of ZE550Ml and ZE551ML file to flash and I got difference....result below(Actually my phone is ZE550ML but I also try to flash ZE551ML dnx.bin ifwi. Bin droidboot.bin too.)

***ZE550ML file after flashed and when xfstk show-up
Continuing to Os... nothing happen no-led no-vibrate no-screen display anything..... nothing .... It's should reboot again right? And come again with 4Colour tap But it's doesn't
***ZE551ML file after flashed, when xfstk showing Continuing to Os... my phone reboot my phone screen display black colour with window connect sound... No-led but it vibrate once everytime when I turn-off and turn-on my phone and I know i can't do anything more cause I flash wrong file... My phone it's not ZE551ML.
4) Before I use window10 to unbrick my phone and passed very well ... Only after my phone brick lately I can't unbrick anymore.

Therefore .... I had doubt about after flash our phone should reboot after get
this Continuing to Os... message in xfstk Our phone doesn't boot probably after reboot and 5-10 Sec pass xfstk starting to show message
reconnecting to device - attempt #1
Until it's over at #20 If I manual turn-on my phone xfstk will flashing it again
when 100% Complete my phone turn-off ....actually it's should reboot but turn-off ..... So we do it like a loop here to revice our lovely phone.

so I don't really know anything that I missed? Cause I try to read from start this topic but no one get this solution since now.

This guide helped me recover my friend's phone.
But I'm facing a problem. After the phone was fixed, my friend used it for about 4-5 hours and after that, the phone rebooted and the USB icon was shown. He tried to boot into fastboot but again the USB icon. Any ideas what would have gone wrong? I've followed every step exactly as described..
thanks

Yesterday I was Installing Skype and during this process I also took a Photo ( battery 55%). After taking the Photo the phone went black. And kept vibrating twice (every minute or so). No way to turn it on, no charging icon. (Windows does detect a device when connected with USB cable, but also disconnects after 2 seconds)
Is this also a way to "hard brick" the phone? I was just on stock MM, no-root.
Would you recommend to try the process in this thread?

First , depending on how long you have had the device re.. Warranty , battery disconnect and reconnect would be my advice .
These devices are well known for going into a coma.
But do try holding power button down for a couple of mins whilst connected to charger.
Power and vol+ too
See if you can reach bootloader /recovery and select reboot from there

thanks, Warranty is void, so tried to press power (+ volume + ) for minutes, but no response. Also disconnected the battery and reconnected again, no change.

Really bricked just by taking a photo, is that possible?

I`ve had my device since launch and only ever experienced sudden switch off -blank screen and vibes - once on early firmware , where pressing a combination of vol and power brought mine out of the coma it suddenly went in . Never happened again since.
If you are sure you are bricked , you will have to unbrick using this thread in OP
:good:

Ok, I tried the method here, seemed to work: but after "continuing to OS" phone shuts off, vibrates twice and doesn't show the bootloader. I've pressed the power button for 10 seconds and power on it will be detected and repeat the process, but doesn't continue with the OS....See screenshot.

Continuing to os , is a common problem been discussed many times on XDA and is resolved pretty easily , providing
1 you have not killed the battery and it still vibrates
2 you have the correct settings in the correct section in xfstk downloader.
3 If no vibes , you have a chance by charging the phone
4 check if your device is being recognised in fastboot during different stages of blank screens , not usually needed but some people have used xfstk which is required for loss of bootloader to bring a temp bootloader , then to only have their own bootloader restored by part flashing , ie , a slight coma state lol.
5 resurrecting your phone , providing you have enough charge and all above is correct ...
Where it says cont..to os ...
Press and keep pressed power immediately at cont to os ....
Release power at first of two vibes and at the same time , hit download.

Rotate between 4 zeros and 5 zeros in xfstk ..

Check my unbrick thread and vid iin my signature ,t contains, performs, exactly all this above
And you can unbrick and be in system in under 15 mins too

thanks, all ok, but point 4, I don't think the fastboot is working. But not sure how to check or change this. I'll try to find how to do this.

You just concentrate on 5 ;) that was a general reply i give to someone else and i copied pasted :good:

mmm , step 5 doesn't work, since the device doesn't connect anymore. Tried pressing the power button like you said in step 5, but no difference.... if i press it 10 sec and turn on with VOL-Down+power (screenshot)it starts doing the FW again ... (have never seen the USB logo or anything on the screen the whole day)

    For those who bricked their phone and facing any of the following issue (Black screen, vibrating only, no fastboot, unable to start, unable to install firmware etc.)
    If you got No Fastboot, No recovery, No Display, hard bricked your device.You must perform sequential steps indicated below, process will include many small steps. Plz make sure to perform all steps in same sequence and same manner as prescribed. Remove all drivers related to mobile you have installed earlier.


    Step 1: Install the Intel Soc USB driver:



    (if you are using windows 8 or 10. it is very important to disable driver signature enforcement. see the sections related to your windows below. (note: if you will reboot pc after disabling it will be enabled again)).

    This Is the driver which help a computer connecte to your Zen2 IntelSoc mode. To install these driver you need to perform special steps if you are using windows 8 / 8.1, 10 . you need to disable driver signature enforcement before installing drivers. below i have mentioned steps needed to install driver for various versions of windows. but first download the needed driver from link given below.
    https://drive.google.com/open?id=0B72QQTXqZSRwR0JGeFI2U3FUZ2c

    Step 1.1 - how to install these drivers:


    (Note: if you see the image like below attached thumbnail and you click install software any way 2 times means drivers are installed correctly. if you don't see image below while installation it means you need to disable driver signature enforcement)


    If you're using Windows 7:

    Right-click the file - iSocUSB-Driver-Setup-1.2.0 choose "Run as Administrator".
    Make The installation steps as usual until you see a small window "Windows Security" requires authentication settings then click on the "install this driver software anyway"


    After This step, the driver installation is finished, continue to section 1.2 for connecting IntelSoc.


    If you're using Windows 8 / 8.1 :
    On Keyboard press Windows + I to show charm bar in the right corner,
    click on the option setting. Choose "Change PC Settings" to enter the PC Settings.
    Choose the General tab and navigate to Advanced Startup section, continue click Restart now.
    This will reboot windows and allows you access to the advanced mode, now select the following options: Troubleshoot - -Startup Settings Advanced Options and then click the Restart button to restart the computer.

    now you will see screen with various options numbered from 1. Find disable driver signature enforcement. And press the appropriate number on keyboard your pc will reboot

    Now Right-click the file - iSocUSB-Driver-Setup-1.2.0 choose "Run as Administrator".
    Make The installation steps as usual until you see a small window "Windows Security" requires authentication settings then click on the "install this driver software anyway"

    After This step, the driver installation is finished, continue to section 1.2


    If you're using Windows 10 :

    On Keyboard press Windows + I or click Start, select Settings.
    In The Settings window, select the Update & security.
    Continue Choose recovery and then advanced startup and click "Restart now".
    When The computer has access to the Advanced screen you will see screen with various options numbered from 1. Find disable driver signature enforcement. And press the appropriate number on keyboard your pc will reboot

    Now Right-click the file - iSocUSB-Driver-Setup-1.2.0 choose "Run as Administrator".
    Make The installation steps as usual until you see a small window "Windows Security" requires authentication settings then click on the "install this driver software anyway"

    After This step, the driver installation is finished, continue to section 1.2


    1.2 Connect Zenfone with computer IntelSoc Mode:

    Now you must complete this step before installing xfstk downloader. it helps to setup device's connection to PC

    on your pc open device manager and find Intel Soc.
    Click to expand it. You will see a single option under here.
    Connect your phone to computer via USB cable,

    now back to the phone, hold power button for 10 seconds to shutdown completely, then press simultaneously the key "power" + "volume down", until phone vibrates. Or computer makes detection sound, wait a few seconds. it will add an item immediately below intelSoC in device manager ?MOOREFIELD? new devices is connected successful.

    Now Download intel android USB Driver and install normally from link below:
    https://drive.google.com/open?id=0B72QQTXqZSRwSU5CdDNuUElEcUE



    ( only after installing the above driver with correct steps and connecting Soc then only install xFSTK).

    Step: 2 Installing xfstk-downloader:

    installation of xFSTK is very simple. download xFSTK setup from the link below. to install. right click the setup file and run as Administrator. click next next simply until you finish the installation process
    Here is the download link:
    https://drive.google.com/open?id=0B72QQTXqZSRweDdfMjlPOGEyTW8
    Now to Unbrick Process.


    ( only after installing the above driver with correct steps) go ahead to unbrick process.

    Unbrick Process:

    -The Necessary files:
    ZE551ML: https://drive.google.com/open?id=0B72QQTXqZSRwV0QyWFRXbjMxaFk

    ZE550ML: https://drive.google.com/open?id=0B72QQTXqZSRwY1AyLUdKdkI3OWM

    After downloading the necessary files extract it. it will contain 3 files:- dnx_fwr.bin, ifwi.bin, droidboot_dnx.img.POS_sign.bin.

    -Run XFSTK Downloader as Administrator, click the second tab at bottom MRD A0 / B0 + MOOR A0 + CRC .

    -Then Go to Options to change the value in the Value Section Override Flag GP 0x80000807. Tick GP value over ride, change device detection time out value to 220 and Click OK is complete initial preparation. (important note: never use wrong gp flag value it may complicate things)

    + First select Firmware files FW DnX: and IFWI: by clicking small three dots:- IFWI DNX 2 dnx_fwr.bin and ifwi.bin file.
    + Now select operating system : skip the first box, in second box select file droidboot_dnx.img.POS_sign.bin

    now switch off your mobile by holding power button for long and connect to pc.

    now click begin download on xFSTK. after that simply power on mobile.

    -Here You may see error multiple times just try to power off device completely and turn on again. flash again and again Until you see success: FW+OS Download complete!

    After that you may see a 4 color screen, just like some TV stations stop broadcasting on TV. You have to wait a little. after few seconds or minutes device will boot into bootloader. wait 10 to 15 min if no success, If not repeat the xFSTK process again. once you get fastboot screen on device go ahead to flash RAW firmware


    Now there are two ways to flash RAW firmware one is Asus Flash Tool (AFT) other is without AFT with help of commands. Personally, i like command method as it is much more reliable than Asus Flash Tool. both methods are provided here under.


    Flash Raw Firmware Using Asus Flash Tool:

    Required Files:
    Asus Flash Tool: https://drive.google.com/open?id=0B72QQTXqZSRwUDZqa0M4SWRObVE
    Raw Firmware File:
    ZE551ML: https://drive.google.com/open?id=0B72QQTXqZSRwb2x1SHg2UUlsT0U ( Link updated to google drive and latest raw firmware 2.20.40.194)

    ZE550ML:https://drive.google.com/open?id=0B72QQTXqZSRwcTBDaXZOYUNBdHM

    Download Asus Flash Tool and install. Run asus flash tool as administrator. And select the phone model. Then select the downloaded raw file and click start button to flash.
    Note: sometimes flash process may go endless. If this happens remove the usb from computer. Kill asus flashtool process from task manager. Now run tool again and flash.


    Flashing Firmware Without AFT:

    For this you need two things first is adb tool and second is raw firmware file both links are provided here under:

    Fastboot and adb tool: ( includes setup as well as independent files ) latest version updated

    https://drive.google.com/open?id=0B72QQTXqZSRwMGVuT0cwRlp2UG8

    Adb fastboot tool for 64 bit windows and for those who are facing issue to load zip files while adb sideload. or unable to load system.img

    https://drive.google.com/open?id=0B72QQTXqZSRwUkFRMl81b1pWa0k

    Raw firmware ( you can use any earlier downloaded RAW firmware file)
    ZE551ML: https://drive.google.com/open?id=0B72QQTXqZSRwb2x1SHg2UUlsT0U ( Link updated to google drive and latest raw firmware 2.20.40.194)

    ZE550ML: https://drive.google.com/open?id=0B72QQTXqZSRwcTBDaXZOYUNBdHM

    Now very first of all, rename .raw firmware file to .zip file and extract all files from it.. now place all files in adb and fastboot folder. ( Note: to extract raw file to avoid extension issue please give firmware file a complete new name ie: "user.zip" or anything you like


    now in folder ( where you placed files from raw firmware and adb and fastboot tool folder) at empty place anywhere in folder hold Shift on computer keyboard and right click with mouse. Now click open command window here.

    perform the following commands

    1. fastboot devices ( see if it is recognized: else plug out usb and plugin again)
    2. fastboot oem erase_osip_header
    3. fastboot oem start_partitioning
    4. fastboot flash /tmp/partition.tbl partition.tbl
    5. fastboot oem partition /tmp/partition.tbl
    6. fastboot erase system
    7. fastboot erase cache
    8. fastboot erase data
    9. fastboot erase APD
    10. fastboot erase ADF
    11. fastboot oem wipe splashscreen
    12. fastboot oem stop_partitioning
    13. fastboot flash splashscreen splash_sign.bin
    14. fastboot flash token MFG_BOM_Full.bin
    15. fastboot flash ifwi ifwi-prod.bin
    16. fastboot flash boot boot_sign.bin
    17. fastboot flash recovery recovery_sign.bin
    18. fastboot flash fastboot droidboot_sign.bin
    19. fastboot flash APD APD.img
    20. fastboot flash system system.img
    21. fastboot reboot


    Phone will successfully reboot into system. don't worry, first boot gonna take a little longer time. so have patience and watch some funny video till phone boots up.


    Now you can install any firmware version via adb sideload. make sure to install latest lollipop firmware before flashing Marshmallow. follow the guide to sideload.

    How to Install firmware using adb sideload:

    First of all go to setting > About >Software information > tap build number 7 times to enable developer options. now under setting go to developer options and find USB debugging here. tick to enable USB debugging

    Now go to Asus website and download the desired firmware and place that file in adb fastboot tool folder. rename the files to your desirable short name ( lets take an example rename it to User.zip). now move your mouse cursor in folder anywhere at some empty place, press and hold the keyboard shift Button now right click your mouse button and open command window here. in cmd type adb devices and press enter ( note it will prompt an option on mobile to authorize the computer for adb. Please authorize this computer. ) after this your device will be listed under adb devices with some number. if not type command once again, if no success this time please ensure you have installed usb driver and authorized computer.
    after adb recognize the device. run the following command

    "adb reboot recovery"
    phone will reboot into recovery ( Note you can go to recovery manually as well. for doing so power down your device. after that press and hold volume + button and press power button as mobile shows asus logo leave power button but keep holding volume button. you will boot into fastboot mode use your volume up and down key to go to option recovery mode. now click power button. phone will reboot into recovery mode.

    once phone reboot into recovery mode find option apply update from adb and press that option with the help of power button

    now go to cmd and run the following command

    " adb sideload user.zip " ( Note: User.zip is the firmware file you download from asus and placed in adb tool folder and renamed so can be replaced with the name you renamed your file)

    now let the computer do its work sit back and relax. once file loaded successfully reboot device.
    ( note first boot always takes little longer time so don't panic have patience and wait till phone boots completely


    if you have any question please post here. use hide button while replying to avoid unnecessary length of post..

    If the guide was helpful to you and your device is alive again. Hope you can hit the Thanks button. it will not take much effort or long time. Thank you.

    Well hello sorry for the silly or stupid question but since I'm new to asus, And I see a lot of peoples bricking your devices I wanted to ask, There are some risk in update it if my bootloader locked and my phone fully stock? I received it some weeks ago and I not rooted or unlocked bootloader yet, so there are some chance to I get in a brick? Like some peoples did? :eek: I going to update next week, but just on case I wanted ask.

    I gonna be very thankful if someone answer me :D
    if you are stock. you can update without any issue. just keep in mind update to latest lolipop first.. ( Z00A-WW-2.20.40.194 ) then to MM
    6
    those who are not able to keep device connected. take care of few steps

    1. in xFSTK option menu change the flag override value to 0x80000807 not 0x800000807 ( don't forget to click gp value over ride)

    2. while connecting to xFSTK attach usb to computer. hold power button for 20 seconds to make sure it power downs completely. then hold the power button down and click power button. wait till device vibrate or computer makes detection sound. leave power button but keep holding the volume button for few seconds

    Ahm question again bro..you mention in op install first to latest lollipop right,, how did you install it,, i mean via twrp or what?

    ---------- Post added at 03:43 PM ---------- Previous post was at 03:38 PM ----------




    Sorry for bunch of questions,, I'm just making sure bro..
    if yoy want to install latest MM. for that purpose you must install official asus recovery.. or if you want lolipop only then you can install it from twrp
    4
    Question is,, if I'm already in android mm,,will my custom recovery still be there? Or do i need to flash it again via adb? Thnks..
    yes you need to flash if you want to install custom recovery . but flash it after updating to latest MM

    if you are on unofficial MM. and you have custom recovery installed. don't try to install official MM. you will brick your device
