[ZenFone 2 General] sukhwant717:
some issue with emms. it is not formatted correctly or it is corrupted. try again complete shutdown . and again try to run commands. if fails then you may have to replace emm or motherboard. which country you live in? i may try to do it remotely
[ZenFone 2 General] sukhwant717:
did you flashed with asus flash tool? if so!! can you go to fastboot. if yesthen go to fastboot and rund commands step by step advised in this thread after step 2. if you cannot go to fastboot then use xFSTK again to enter fastboot

raw firmware link is provided in this thread
[ZenFone 2 General] Nikeum:
Hi everybody,

I have read all the pages and did not find a solution of my phone disconnecting after firmware flash.

Basically when xFSTK sais that is going to OS flash my phone disconnects.

Should I call it a HW issue?
[ZenFone 2 General] sukhwant717:
try ifwi from latest MM firmware. if still same!

put your phone on charge for 5 hours with original charger. after that open back panel of the phone and disconnect battery connector. place small piece of paper under it so it do not connects to motherboard. leave it disconnected for a week. then try again
[ZenFone 2 General] Nikeum:
To be more clear I should use the ifwi.bin file from the latest MM .223 and keep the same dnx_fwr.bin and droidboot_dnx.img.POS_sign.bin?

I have leaved the phone to charge, it is vibrating from time to time .

Can you explain why I should keep the phone with the battery disconnected for one week?
[ZenFone 2 General] castagnier:
I have a problem my asus stayed on black screen only vibrates this step when I was restarting (turn it off and on) and now the pc tells me that the device is not recognized I already have all drivers installed

If anyone could help me I would appreciate i

How to get back to TWRP / custom ROM after doing this?

Even if I flash TWRP I am not getting the TWRP recovery, it just goes back to fastboot mode.

NVM solution found

I had flashed to MM that's why bootloader got unlocked
[ZenFone 2 General] sukhwant717:
either drivers are not properly installed (may be you do not disabled driver signature enforcement) else faulty usb cable or connector. finally sim flex may be faulty
[ZenFone 2 General] sukhwant717:
yes ifwi from mm.223 and other files same.

even though its vibrating. battery may be 20 or 30 percent. while performing system on chip (xFSTK procedure) it require lot of power. hence need good battery power as well as good usb power source. so use Good quality fast charging cable and good usb port.

leaving phone disconnected from battery is to discharge motherboard capacitors discharge completely. due to no proper firmware phone is unable to send reset signal to ram. the purpose is to reset every component on motherboard completely. if you do not want to wait for a week. you can use wire to short random multiple points on motherboard (only after removing battery connector) and wait for 24 hours and retry.
[ZenFone 2 General] KA66six:
Every command fails after step 4. Cant boot into any other mode - just get usb logo or fastboot mode with 1234... serial number

please advise ...
[ZenFone 2 General] sukhwant717:
restart phone in fastboot mode..and try again. if still fails flash dnx, ifwi, fastboot, recovery and reboot bootloader and try again. still problem PM me
[ZenFone 2 General] Nikeum:
Tried to flash after 3 days, no luck :(.
[ZenFone 2 General] bblokar:
Yes, my device is now alive, but I've problems upgrading it to stock android 6 (4.21.40.223), I do put it in the root folder but looks like it do the upgrade, but when I turn back to system it's still 5.0 (2.20..40.194).

It did work for me for the first time I did a complete restore, but then I installed TWRP, it actually even worked, but now I need to diagnose the problem, maybe I just need to upgrade ifwi first and then go from there via stotk update.... Or maybe I'll try to root it on 5.0, get the twrp, but need a bit of research of which recovery to put, because I got some modded twrps for A00D ZE551ML....

I'm used to 7.1.2 I have (AICP now for a while, previously crdroid, maybe will give a shot to clean LineageOS) on my LG G3 D855, I don't have much experience with Intel Atom platform, I mostly did snapdragons and Exynos, but this phone is acting weird since I first brought it to life successfully, upgraded with stock rom successfully, and now dunno what should be the problem...

Maybe will try a little trick and try to convert official image to .raw and try to flash it with flash tool, or maybe will change moded ifwi to stock rom's archive and flash, or try to update ifwi via sideload and then flash it "ASUS stock way" from root folder, we'll see, need to do a little research first, haven't even read everything what might be a trick there, as I said, I don't know this platform very well...

Bootloader is unlocked btw, but for IFWI version it shows me -0094.0173
[ZenFone 2 General] sukhwant717:
be aware while being on custom recovery never ever go near AFT...

now step by step

flash stock raw with commands

then after first startup factory reset device and sideload latest MM

then again after first start perform factory reset.

now use modder tool to unlock BL, flash TWRP, root etc
[ZenFone 2 General] michaelnishi:
Hello!

First of all, thanks for all the help you're providing to people, you're awesome!

Thanks to your tutorial I managed to revive my ZE551ML. (I had ran into a problem trying to get into recovery, but after a few searches I came across a way to get into it if/after being rooted. It's updating to MM via sideload just now!)

Thanks again dude!
[ZenFone 2 General] istafakhan33:
Thanx a lot for this wonderful guidance, my phone got rebirth
[ZenFone 2 General] ketogeno:
Thank you! Very helpful.

However on my Windows 10 x64 machine there was no way to use Asus Flash Tool (no devices to select from).

Using adb commands worked perfectly!

Thanks again!!!
[ZenFone 2 General] sukhwant717:
command method is perfect. AFT bricks devices to unrecoverable state
[ZenFone 2 General] istafakhan33:
Thank you for this wonderful guidance,I have recovered my zenphone2, ZE5551ML, i installed latetst LP raw firmware, then i unlocked its bootloader through asus unlock tool, & through adb & fastboot i installed TWRP recovery, Now i want to flash nougat custom rom, I have RR 5.8 and Lineage 14.1, i tried to flash them, but all showing error, RR shows that no MD5 file after that something erro 255, Lineage installing time it shows some issue with ifwi version, then error7 occurs, then i recoverd back from my backup,. Now what should i do to flash custom rom of nougat version, any suggestions r most welcome
[ZenFone 2 General] sukhwant717:
after unlocking BL factory reset device. then flash latest twrp from twrp website. once again factory reset device. and the sideload or flash custom rom you prefer
[ZenFone 2 General] Saumitraa:
Not Working!

This is not working for me! I did everything as mentioned, right from the installation of the softwares to the flashing from the asus flash tool! Flash tool says "Flash Image Successfully" But my phone is stuck on the ASUS logo! Please Help!
[ZenFone 2 General] sukhwant717:
use command's method. if still issue. then ur data or cache partition may be corrupt. format that with twrp and repair in twrp.

It was like that before in my case, so i just redo everything with copy paste command (not typing in fastboot method)
[ZenFone 2 General] chairsz:
i originally used this method to unbrick phone, and then foolishly tried to flash a custom rom cant remember which one, bricked it again, tried the unbrick process again and when i got past the fastboot commands; i got the "pass" in xfstk tool thingamajig and now i have the infamous usb cable symbol displaying and nothing else. ALSO windows wont detect the phone anymore after this after trying multiple usb's (even though it detected the phone when i unbricked it the first time.) has any one had that extra headache where windows itself, device manager wont even detect the phone on top of the other foolery? btw i disconnected and reconnected battery terminals and it booted back to that crap-olio usb cable symbol thing. i know theres some life left in it.
[ZenFone 2 General] sukhwant717:
remove all the drivers and xFSTK. delete temp files. reboot and flash intel SOC driver. connect the phone to pc and reboot. do not install xFSTK until you are detected as moorefield. check sim flex connection on the both sides disconnect and reconnect

4 color screen

please help me,

i already do every step & still cannot solve my problem,

stuck at 4 color until fed up &stress...

anyone can help?:crying:
[ZenFone 2 General] sukhwant717:
buddy put your device on charge for few hours. after that open back cover and disconnect battery connector. leave it disconnected for 2 days. connect and try again you will overcome the situation. before doing so you can try swaping ifwi
[ZenFone 2 General] mezymerican:
Thanks for your suggestion i will try charge & disconnect battery :good::good:

but what mean by swaping ifwi? i dont get it :confused:
[ZenFone 2 General] sukhwant717:
ifwi you select in xfstk. use ifwi from latest marshmallow firmware or lp firmware vice versa,.
[ZenFone 2 General] mezymerican:
where can i get it? how do i know its from latest marshmallow firmware or lolipop firmware?

can give me download link?:angel:

Best tutorial for unbricking hands-down

This is BY FAR the most comprehensible and well laid out tutorial on unbricking your Zenfone 2.

A couple months back I used a youtube tutorial and managed to unbrick my device but then a problem reoccurred and could not by any means figure out how to unbrick it again (using the same video).

Fast forward to today and I randomly decided to pick up my device and try again. I discovered this tutorial and following the steps exactly, it worked amazing! I thought this phone was dead and gone. Thank you sooooooo muchhh! Amazing work on the tutorial and also the links are all alive (as of writing) and very fast to download.

:victory::highfive:
[ZenFone 2 General] sukhwant717:
Thank you for feedback! glad to know that guide was helpful.
[ZenFone 2 General] hellbraker:
Hi sukhwant717, I have been reading almost all post since last year. I'm experiencing the same error as most people here (for example omissis, mano2, daveOF and SirAnKeKu). That is, stopping when it decides to go to the OS.

I will try removing the battery connector and lets see. Please see my logs. One where it gave an "The host controller has set the Transaction Error (XactErr) bit in the transfer descriptor's status field" error.

A question in mind. Where can i get the droidboot_dnx.img.POS_sign.bin from Android 6? I have the other two dnx files.

If you can share your mobile number, ill add in WhatsApp for further instructions.

Thank you
[ZenFone 2 General] hellbraker:
Ok an update. My device no longer vibrates. Again tried flashing, during which I accidentally set the value to 0x80000 and tried once.

Changed back to the instructed value. Simply for trial sake unchecked Enable GP Flag Overide. This made the whole process to loop after showing Continuing to OS. That is, attempts are made only after a whole cycle, not like the previous one where the cycle is not repeated. Even after the 20th attempt, the Device Status (scanning) is 1. And all this while "Moorefield" remains in Device Manager with automatically connecting and reconnecting at each attempts. It still is shown under Intel SoC.

The moment I tick Enable GP Flag Overide and start again, the device gets disconnected and then I have to manually switch Off and ON again.

No asus logo and bootloader showing black screen

Hi, thank you for making steps easy to follow. I was able to revive my ze550ml by following the steps. Since continuing to OS on xfstk failed I used the ifw and dnx of 551ml and use the OS image of 550ml then flash using AFT raw LL. It seems that there were still corrupt part in my phone that when I restart no asus logo, black screen on bootloader but it is connected.

Is it okay to use the latest LL firmware in putting it on xfstk? like the ifw,dnx and os image?

Thanks,
[ZenFone 2 General] zcatrix:
Hi, may I know which of the ifwi,dnx and droidboot images do I need to get inside the latest LL build.

Still stuck on 4 bars

I always successfully complete the FW + OS download but never get into the fastboot mode. I have tried keeping the connections on the inside of the phone unplugged and tried it all again, but still I don't get passed the 4 color screen. Am I missing something. Can someone please help me.
[ZenFone 2 General] demonntl:
Hi friends, thank yo your guide, my ZF2 550ml back to life, it can boot to OS but:

- there is no splashscreen when power up. i tried to reflash the splashscreeen but cannot work.

- i cannot go to recovery to side load, when i try "adb reboot recovery" or shortcut button, it went black then restart. i tried to flash stock recovery but not work.

any help ? thank

---------- Post added at 09:29 AM ---------- Previous post was at 09:25 AM ----------

i suggest that you use the Z551 ifw and dnx, if it success. you connect and again and flash z550 ifw and dnx, if success, you reboot, left it for 3 mins, then try to click volume button a few times, hopefully you got to fastboot. the next steep is the same as guide.
[ZenFone 2 General] zcatrix:
Does it show on the device manager? Have you tried to reboot the device then plug the usb cable on the computer. Then check if it was detected on the device manager? Your phone might have booted to bootloader not being aware that it was running in the background.
[ZenFone 2 General] xpoudel:
Yes I Have tried the above methods and when on the 4 color screen my device is not detected by my PC. I have tries switching the phone on by all the ways possible, cable/no cable, volume keys..but to no luck...
[ZenFone 2 General] gappot27:
hi can i use this unbricked method to Zenfone 5 A500CG? If can how can or where do i get the necessary file for Zenfone 5? TIA :good:
[ZenFone 2 General] sukhwant717:
method is almost same. you need different files. and do not use gpflag override. i will try to post files. else you can google it

Revived My Ze551ml

Thank You xda-developers because you guys are there my phone revived again, without spending a penny.. :):)::D:D
[ZenFone 2 General] hellbraker:
Finally fixed! (just change the battery)

I got my fixed (for the time being). I ordered a new batter from AliExpress. Followed a video tutorial from You Tube and did a DIY to replace the battery.

https://www.youtube.com/watch?v=xtB8LRWtp2Q

Thank God.

But all is not perfect though. I can't seem to shut down the device. It instead restarts. Maybe this has to do with me giving the wrong GP Value of 0x80000 while in xFSTK.

Anyways, thanks to all.

Bricked Asus Zenfone 2 [ZE550ML] black screen, only vibration

hello sir, i update lolipop to marshmallow firmware on Asus Zenfone 2 [ZE550ML] using ADB sideload method. after few hours my device hanged and i switch off it and trying to restart but there are only vibration.

only vibration, black screen...

i'm trying your method.

Intel Android Driver Installed. Done...

iSocUSB-Driver_v1.2.0 Installed. Done...

MOOREFIELD driver Installed. Done... (it means detect my device alive)

xfstk-downloader_v1.7.0 Installed. Done...

opend as administrator xfstk-downloader and i connect my Asus Zenfone 2 [ZE550ML] and pressed power button for 20 second and release thean MOOREFIELD device detected and "firmware download completed. continuing to OS..." than can't reconnect and attempt starts like "Reconnecting to device - Attempt #1 to #20" (see SCREENSHOTS below i attached).

sir tell me what to do. i'm trying last 2 days. many time i installed/unstalled these drivers and software from laptop. but didn't get any solution. Thank You.:crying:

Bricked Asus Zenfone 2 [ZE550ML] black screen, only vibration

Asus service center guy told to replace Motherboard it cost me around Rs.10,600.:confused:

sir can u provide me latest ifwi file link...?
[ZenFone 2 General] hellbraker:
I think they are trained to say that. It is through service they get profit.

MayurTheHunter try to buy a battery online (around 800 Rs), then give it to a repair shop.

Most of us have the error you suggest. Some get through, some don't. For us who don't, swapping in a new battery may do the trick. Good luck.
[ZenFone 2 General] reversegear:
Don't go to service center.. their knowledge is limited and they charge u hefty amount

I got my device back from dead using xfstk

Try charging ur phone over night and try me too had same issue after charging it overnight tried xfstk it worked

[ZenFone 2 General] sukhwant717:
are you able to go to fastboot mode with pressing and holding volume plus button and turning on?

while phone switched off put device on charge with original charger for 1 hour
[ZenFone 2 General] MayurTheHunter:
Bricked Asus Zenfone 2 [ZE550ML] black screen, only vibration

no. i'm not able to go to fastboot or recovery mode.. its just showing basic Asus logo and powered by android than switch off...

what do u think is there any Hardware issue?????
[ZenFone 2 General] sukhwant717:
did you opened your device? it may be faulty battery or components. any ways.. connect you phone to pc turn off phone. now run xFSTK load files and click begin download it will start waiting for device. now simply turn on mobile with power button only. after xfstk succeeds you will enter fastboot mode. and flash firmware without AFT. do not skip any command.
[ZenFone 2 General] MayurTheHunter:
Bricked Asus Zenfone 2 [ZE550ML] black screen, only vibration

yes, i opened device 2 times. vibration not working. but now i'm able to go to fastboot mode, recovery mode even my device is boot 2 times when on charging only otherwise it's stuck on Asus logo and switch off.. when home screen appear screen is blinking, like i'm open settings than every second settings reopen again and again. when at home screen ram booster automatically boost ram repeatedly. so device is not bricked..

now my device running on WW_ZE550ML_2.20.40.92_20150918 version. should i need to flash latest stock lolipop firmware WW_ZE550ML_2.20.40.156-user.zip??????
[ZenFone 2 General] sukhwant717:
seems like you need to disconnect battery connector sim flex connectors and connect those again properly. then flash raw again. then you can update to desired firmware
[ZenFone 2 General] demonntl:
Hi friends, thank yo your guide, my ZF2 550ml back to life, it can boot to OS but:

- there is no splashscreen when power up. i tried to reflash the splashscreeen but cannot work.

- i cannot go to recovery to side load, when i try "adb reboot recovery" or shortcut button, it went black then restart. i tried to flash stock recovery but not work.

any help ? thank
[ZenFone 2 General] zpr06:
thanks bro you thread is great n fix my phone

thanks again
[ZenFone 2 General] sukhwant717:
have you tried to flash raw? do you get any error when you try to flash raw
[ZenFone 2 General] demonntl:
Yes i flash raw, with both Asus flash tool and Fastboot manually.

One thing is that, only Raw 5.0 LL work, Raw 6.0 MM will kill my phone, and i have to use this guide again.
[ZenFone 2 General] sukhwant717:
buddy i think there is no raw 6.0 file.. flash latest LP commands method. after first startup reboot to recovery. and factory reset device. now again after first startup go back to recovery and sideload latest MM zip downloaded from asus website.
[ZenFone 2 General] demonntl:
you can find the MM raw file that i mentioned here: https://yadi.sk/d/irxWikyFtvPhy

By the way, i flashed LP raw file, no error at all, my phone booted to os and work but there is no recovery. i cannot enter recovery by button or command.

Normally, you boot to bootloader (fastboot), then u choose recovery by volume button. but mine will reset the phone if you choose recovery.

The unlock tool of Asus doesnot work as well, if i run the tool, its restart my phone the BL is still locked.
[ZenFone 2 General] sukhwant717:
what is the result of fastboot flash recovery command?
[ZenFone 2 General] demonntl:
thank you for your patient.

this is the result. after this, choosing recovery in bootloader give me a reset and boot to android.
[ZenFone 2 General] sukhwant717:
recovery in raw is usually in .bin format and signed. can you show me pic of extracted raw files from which you are flashing recovery?
[ZenFone 2 General] gioele 1334:
Thanks dude! just made a batch file to autoexecute all the commands to flash the files, Working like a charm
[ZenFone 2 General] demonntl:
Hi friend, I flash again, the result is success, no fail or error at all.

Recovery was extracted from WW_ZE550ML_2.20.40.156_20160815 raw.

still no recovery, when i boot, no asus logo as well, the screen keep light until booted to os.
[ZenFone 2 General] sukhwant717:
that is probabaly you used wrong files in xftk. you have to flah correct files in xfstk.
[ZenFone 2 General] sukhwant717:
here are two possibilities. a you got some corrupt partition especially cache. or its just a simple file conflict.

open device and disconnect battery connector for a while. and connect back.

download unbrick files ( to use in xFSTK)again from unbrick thread. even if you think its same. and try again
[ZenFone 2 General] demonntl:
Thank friend, i hope you are right. i will give another try.
[ZenFone 2 General] sukhwant717:
use ifwi file from latest MM. if still same disconnect battery and leave it for few days and try again
