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=0B7...0JGeFI2U3FUZ2c

Step 1.1 - how to install these drivers:

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=0B7...U5CdDNuUElEcUE



( 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=0B7...DdfMjlPOGEyTW8
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=0B7...0QyWFRXbjMxaFk

ZE550ML: https://drive.google.com/open?id=0B7...1AyLUdKdkI3OWM

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=0B7...DZqa0M4SWRObVE
Raw Firmware File:
ZE551ML: https://drive.google.com/open?id=0B7...2x1SHg2UUlsT0U ( Link updated to google drive and latest raw firmware 2.20.40.194)

ZE550ML:https://drive.google.com/open?id=0B7...TBDaXZOYUNBdHM

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=0B7...GVuT0cwRlp2UG8

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=0B7...kFRMl81b1pWa0k

Raw firmware ( you can use any earlier downloaded RAW firmware file)
ZE551ML: https://drive.google.com/open?id=0B7...2x1SHg2UUlsT0U ( Link updated to google drive and latest raw firmware 2.20.40.194)

ZE550ML: https://drive.google.com/open?id=0B7...TBDaXZOYUNBdHM

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.

any how for those who bricked their phone: use the following guide to unbrick ZE551ML

http://forum.xda-developers.com/zenf...one-2-t3284256

Read the above guide carefully. but even after that people are unable to unbrick. people who are unable to flash raw. perform step 2 of the above guide. after that do not use the asus flash tool. Try the following guide,

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.
open command window here. ( where you places files from raw firmware and adb and fast boot tool folder)

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 erase_token
4. fastboot oem start_partitioning
5. fastboot flash /tmp/partition.tbl partition.tbl
6. fastboot oem partition /tmp/partition.tbl
7. fastboot erase system
8. fastboot erase cache
9. fastboot erase data
10. fastboot erase APD
11. fastboot erase ADF
12. fastboot oem wipe splashscreen
13. fastboot oem stop_partitioning
14. fastboot flash fastboot droidboot_sign.bin

18. fastboot flash boot boot_sign.bin
19. fastboot flash recovery recovery_sign.bin
20. fastboot flash APD APD.img
21. fastboot flash system system.img
22. fastboot reboot


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

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
