I had the same issue, this thread really helped me a lot too. but in the end I had to use another RAW file, then the flash tool worked right away. you can look here, there's a link to google drive. https://xdaforums.com/zenfone2/help/guide-flash-stock-rom-asus-zenfone-2-t3588276

look on the drive for unbrick zenfone2 and double click, then you'll see the raw file and flash tool in a download.

Hello,

First of all, thanks for such a detailed guide.

I also have a ZE551ML phone, which is bricked a few weeks ago, just 1 week after its warranty expired, and came across your guide while searching for a solution because the service tried to bill me outrageous amount of a repair fee.

I have tried the steps but stuck on the

XFSTK-STATUS--Firmware download completed. Continuing to OS...

XFSTK-STATUS--Reconnecting to device - Attempt #1, 2, 3...

XFSTK-STATUS--Timeout to detect the device, make sure to charge up your phone before flashing

part. Seeing others also having the same problem, I decided to try the various suggestions to this issue.

Namely, trying an IFWI file from MM firmware, putting the phone on 24h charge, waiting for one week with all the connections separated, etc.

Finally, I am out of options to try but decided to write here before going out and buying a new phone.

So, any other suggestions? :)

Thanks in advance.

Hello, i'm also at wit's end here trying to get things done, so far no luck, here's my symptoms:

Windows 10 x64(yes i did disabled drive signature verification)

Zenfone 2 ze551ml(2gb RAM)

Drivers - all good

xFSTK - i tried to use both FW DnX and IFWI from 6.0 - FW DnX didn't got through, so it's already no go.

With all 5.0 files usual process goes till "continue to OS", phone seemingly reboots(disconnects and vibrates again) but screen doesn't light up and countdown hit 20 tries and ends at that, I tried holding Volume down a bit longer, tried holding it through whole process, tried holding it on "continue to OS" step - nothing.

With IFWI 6.0 process goes pretty much the same except on "continue to OS" it just disconnects - no vibrations after that.

I also tried both turning phone on after i start download and vice versa

I tried to charge it for 2~ hours - charger didn't even heat up a bit, nor the battery, so i have a question - do i put charge it while it's on(it'll vibrate every 2~ minutes) or off? - what i wrote earlier is a result with phone turned off.

Or maybe my battery commited 'sudoku' and holding me back? But why would phone even vibrate if it was so ...

UPD.: It no longer vibrates if i try to turn it on, not even with volume down, it probably only turn on if i connect it to pc, will see later, for now, i'm fully open to suggestions...

UPD2.: I 'restored' vibrations, also after more thorough testing on another PC i can say that it's probably my battery that 'commited sudoku' and successfully refuses to charge however i try to charge it, so i believe that i would need to replace the battery.

hi. my zenfone 2 phone is not opening on without charging, stuck on third asus logo on loading system screen and turning off...... but if i charge, opening without any boot problem.

i tried hard reset and again i format with adb sideload way...

my phone is not rooted anyway.

how can i fix it without to send to service center?
[ZenFone 2 General] Aioros_Y:
To anyone still stuck on the "Continuing to OS" part of the xFSTK download, even after religiously following the guide and trying every possible ifwi files, please consider replacing the battery (as somebody already said in the previous pages). It might be that your Zenfone hasn't enough battery to reach the bootloader (if that makes sense). Solved the problem for me.

Tips

Greetings guys,

Firstly, a million thanks to OP and all here for the information. I was about to get a new phone but this thread saved my money.

I have a few tips which might help those who are still stuck at xFSTK-Downloader. I tried with the files provided here for 2 days but no luck. I end up at Firmware download completed. Continuing to OS... and fails. What i did was change the ifwi file. I downloaded another version of lollipop firmware from Asus website and extracted the IFWI file.

I only changed the IFWI file and used the other same 2 files provided here. I tried with 6.0 IFWI files but it got bricked again. I then used IFWI from 5.0 and my phone is up and working now. Use fastboot for flashing. I feel its better than ASUS Flash tool.

I wish you luck guys. Took me 3 days but finally got it working. I used windows 10 pro 64 bit to revive my phone. No issues just make sure drivers are installed correctly prior to running xFSTK. Disable driver signature verification, very important.

[ZenFone 2 General] Kuromeshi:
Hey all! Maybe this is a dumb question, but will this process erase the data on my phone? I have important documents and pictures that were not saved to an SD card. Here's my initial situation: Last night, my phone was at about 5% battery. I went to charge the phone, but after 15 minutes it displayed that it was fast charging but still at 5%. I unplugged the device and it hung and said it was still charging. I was able to hold power and select restart, but when it tried to restart, the phone screen remained black and it just vibrated twice and did nothing else. it proceeded to do the same thing for about 20 minutes. I tried to hold volume up+power and go into safe boot, but I got nothing. I let it charge over night, still nothing. I disconnected the battery and let it sit for 20 minutes before trying to boot it up again, but it simply proceeds to vibrate with a black screen. The orange power LED doesn't display anything and the device doesn't get warm when attempting to charge either. Should I attempt this process, or opt to replace the battery? I don't want to lose my data. My phone ran great until now, I've had it for around 2 years, any response is appreciated. :(
[ZenFone 2 General] fabianinsane:
Greetings Kuromeshi. Firstly, there is no such thing as a dumb question. No harm in asking when in doubt. YES, this process will erase your phone to factory standard. You can try to change the battery and see if that helps. If it doesn't, then i advise you to proceed with the steps in this thread.

Hi! i'm trying to recover my zenfone after my lineage os bricked ... I managed to reach fastboot screen using marshmellow's ifwi, but when i tryed to flash with AFT the LP raw file (maybe that's the mistake) it said me that partition couldn't be mounted. Now i can't reach fastboot screen anymore and I can't flash with xFSTK because it blocks to "Continuing to Os". What can I do?
[ZenFone 2 General] felipel2:

Greetings, use android 5.0 ifwi file. I was having the same issue when i used android 6.0 ifwi file.
[ZenFone 2 General] xeneixexxx:
hello, the problem I have with zenfone 2 is that it is locked in fastboot, originally the phone came with android 5, official update to 6, then root and custom rom 6 and 7, finally custom rom 6 and brick.

try with the sukhwant717 guide and I have 2 problems:

1- in xfstk-downloader I never saw the 4 color screen .... "After that you may see a 4 color screen, just like some TV stations stop broadcasting on TV. 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 ", after" FW + OS Download complete! " It restarts in fastboot but I never see the 4 color screen.

2- in adb I get the error: FAILED (remote: GPT command failed) when I run fastboot oem partition /tmp/partition.tbl everything else without problems, but in the end it restarts and I remain stuck in fastboot.

I think that the error is that I am using files from android 5, both the raw and the dexfstk-downloader, and since I was on android 6 when I suffered the brick I would have to use alchemies from android 6 above all in xfstk-downloader and then flashing a raw or system.img with all files also from android 6. other things I can not think of.

Does anyone have the files on android 6 for xfstk-downloader?
[ZenFone 2 General] fabianinsane:
Greetings,

I was on android 6.0 when i bricked my phone. Using ifwi file from 5.0 only managed to unbrick my zenfone 2. I used these 3 files :

1. dnx_fwr.bin

2. droidboot_dnx.img.POS_sign.bin

3. ifwi_ann_a0-mofd_v1-ze550ml.bin

fastboot devices

fastboot oem erase_osip_header

fastboot oem start_partitioning

fastboot flash /tmp/partition.tbl partition.tbl

fastboot oem partition /tmp/partition.tbl

fastboot erase system

fastboot erase cache

fastboot erase data

fastboot erase APD

fastboot erase ADF

fastboot oem wipe splashscreen

fastboot oem stop_partitioning

fastboot flash splashscreen splash_sign.bin

change device detection timeout to 120 seconds. after that click begin download it will start waiting for device. then connect the phone and simply reboot it. program itself will force into required mode
[ZenFone 2 General] xeneixexxx:
Thanks for responding, I still can not see the 4 color screen, and with AFT I always get an error. I think my problem is with xfstk, if I do not see the screen with the 4 colors it must be because the process is not completed properly, but I do not know where to get a new dnx_fwr.bin that is from android 5 or 6, to continue testing, to the other two files I take them out of the roms and I'm still trying, but I think I'll give up, it must be the emmc's problem that I can not partition ...:(:crying:
[ZenFone 2 General] fabianinsane:
Greetings mate,

1. dnx_fwr.bin - use the one provided in the front page by OP

2. droidboot_dnx.img.POS_sign.bin - use the one provided in the front page by OP

3. ifwi_ann_a0-mofd_v1-ze550ml.bin - this i extracted from asus original 5.0 rom

make sure firmware and OS completed comes out in xfxtk. from there on in fastboot, do steps one by one, if any command fails, 'fastboot reboot bootloader'

keep on trying mate, you will succeed.
[ZenFone 2 General] rohn4:
I had problem with blank screen but slight brighten..when i'm trying to poweron or recovery shows same just vibrate and that screen. I performed xfst process too..and it bring me there but can't get into the bootloader mode. Any suggestions please.

And one more que. Can i use adb sideload method if i get into bootloader? Bcz i have firmware zip file.. Or i go with this raw images file to flash tool. ??????
[ZenFone 2 General] marcosmapf:
Hello everybody

I'm currently experiencing this issue, and I have gotten past the "Success: Download of FW Completed." section on xFSTK. The rainbow screen appears on my cellphone, but it disappears a few seconds after and no matter how much I wait the bootloader won't load.

Things to note:

* I have waited more than 10 minutes, more than five times

* I have tried pressing the volume-down button as the rainbow screen disappears, and after a few seconds it sometimes brings me to the Bootloader window, but its hella buggy, with a white window convering half of the screen and the other things flashing.

* The "Scanning: MARRIFIELD, MOOREFIELD, CARBONCANYON TARGETS DETECTED: " has the value 1 when the rainbow screen appears, but then becomes 0 half-way through the load, and the rainbow screen becomes a little darker. Nothing loads afterwards, no matter how long I wait.

This connect/disconnect has happened several times during the process (but If I keep the volume-down button pressed it sometimes fixes the problem)

* If I simply press the power button a few seconds after the rainbow screen disappears, it appears again (as if it was loading again) and the targets detected becomes 1, but then becomes 0 afterwards.

* When the USB-like icon appears, right before the "Success: Download of FW Completed.", it initially becomes red and the download fails, but if I press the volume-down button (so it detected the device) and try again it finishes the proccess (or I can just wait a few seconds and it will work automatically). I can then press Being Download again and it brings me to the Rainbow screen.

*I also hear a noise similar to the usb-disconnect noise a few seconds after the rainbow disappears, most likely indicating the device was not found(?).

When I verify if the device is connected through the "fastboot devices" input on the command line it doesn't find a device (even if I reconnect the cellphone) and the Asus Flash Tool doesn't install because it says I'm missing a dll. It seems like the device is not being recognized even thought it was earlier by xFSTK Downloader (and even if xFSTK recognizes it, it isn't recognized on the cmd window (I extracted the files and added everything to the same folder)) .

Can anybody lend me a hand? Thanks!

My phone died after trying to update from L to MM, blackscreen no boot no charge, could'nt access recovery or anything, your instructions saved my phone ! I almost bought a new one, now I won't need to! Least I could do is buy you a beer! Thanks a lot!

For anyone having trouble booting to recovery after use xFSTK :

I coulnt access recovery after the colored splash screen like the tv, after some time ,the screen would just go black with the phone backlight on, the phone was detected by AFT, but when I tried to flash many times nothing did happen, but I was able to flash raw using fastboot and the phone started working again after that.

I was even able to try again the update to MM and it worked this time! (Prolly it broke before cause I was using twrp instead of stock recovery lol)

Holy ****... After six goddam hours, this beast lives.

Lol, I must have flashed this thing like 70 time thinking they were all bad flashes. Reassembled it 4 times. Turns out the larger data connector on the mother board was dirty. I put some technical grade isopropanol on it, scraped the top and inside of the connector with a super fine flathead screwdriver and dabbed it up with microfiber cloth then finally, rinsed it with more iso. It ****ing worked.

Getting to the point where you see the fastboot screen work for the first time in two years but fastboot connectivity is zero.... just plain weird. Th crazy part is the moorfield protocol worked but fast boot connectivity was null.

[ZenFone 2 General] :
I downloaded the most recent firmware from the website. In the ifwi.zip I find both dnx_fwr.bin and ifwi.bin. However where do I find the droidboot_dnx.img.POS_sign.bin? It doesn't seem to be in the firmware. The only thing I find of similar size is droidboot.img, but it's not in .bin format. Anything I have to do to change it to the correct format?

Phone doesn't stay connected to xfstk

I had a custom rom based on Nougat on my ZE551ML, it suddenly shut down (low battery) after which it refused to turn on. Just vibrates 2 times intermittently and doesn't respond. SO I followed this method and proceeded to unbrick. However the phone gets disconnected from xfstk just after the firmware write process completes and then fails, never proceeds to OS. Any help regarding this?
[ZenFone 2 General] :
I scrolled to multiple pages and didn't find a solution to this, other than some user saying that using Android 5.0 files from the official firmware worked for him. I can't find one these files though, as I posted before you.

Luckly I had another phone who had ghost-touch problems (battery was good), switch only the batteries, and the xFSTK process worked.

The other phone is now bricked though, with the same problems as before (doesn't get to OS).

So I wonder if the using different files will unbrick the other phone?

Willing to try if anyone is willing to help me

tried flashing again but no help
[ZenFone 2 General] :
Thank you for your answer, but it worked on one of my phones after changing the battery, but on the other phone it get stuck on firmware complete (doesn't go to OS). It disconnects the device from the computer after. You are telling me to do this a million times until it works? Also are you saying this form personal experience because I have done this 30 times and it still stuck on firmware. Thanks :)
[ZenFone 2 General] fabianinsane:
Greetings,

I was having the same issue (doesn't go to OS - stuck for 3 days and trying numerous times) until i changed the ifwi file to 5.0 version taken from Asus rom. The 6.0 ifwi file didn't work for me. Try to force start the device when it disconnects. I am speaking from personal experience.

whats wrong?
[ZenFone 2 General] sukhwant717:
read once again and do step by step as suggested. if you are unable to keep the phone connected for the xfstk process. change device detection timeout to 120 seconds. click begin download. it will start waiting for device. then (Assuming you already switched off mobile mobile holding power button for 10 seconds min) when program starts waiting for device connect phone to pc and switch on simply pressing power button. program itself will force device in required mode. do not press volume buttons. use correct files as per device model. charge device with original charger or good charger for min 6 hours before you try the process

Fastboot doesn't detect device -> use official Asus drivers.

If fastboot doesn't recognise the device, use official Asus driver from their website.
[ZenFone 2 General] saurabhshri:
Few Tips :

1. Install official Asus drivers from their website (sorry I can not post links, not enough Karma).

2. If you get `(data write failure (Too many links))`, although you were able to execute few commands earlier, try new cable. It did wonders.

3. If you're getting `???????? fastboot`, try another cable, or even reflashing firmware and OS through xFSTK.

4. I wasn't able to go to recover by pressing up or anything rather on fastboot screen. Don't worry, just carry on with fast boot commands.
