Asus zenfone 2 lost Bootloader. No display, no USB sign, no vibratio. - ZenFone 2 Q&A, Help & Troubleshooting

Help requested.
My Asus zenfone 2 ze550ml lost its Bootloader.
I used the xFSTK method.
Before going through the process, my phone was-
*Vibrating
*display was stuck at showing Asus logo in a white screen (that screen when you try to enter into the recovery mode) .
*Battery logo showing while plugged to PC or charger.
I used the xFSTK method first time. Following every single instructions.. And It probably showed "successful" for the first time!
But something definitely went wrong I don't know!!
And Now,
There is
*No vibration
*Display not turning on
*No USB sign while connecting to the PC.
But
ISOC is still detecting my device as "Moorefeild device" And so the xFSTK programme!
I am still trying to flash Bootloader using the xFSTK programme. But its failing.
Showing these from time to time
*Error encounter while FW download, Aborting
*firmware download skipped, continuing
And soany failure and errors!
Is there any other way I can fix this problem and regain Bootloader?
Please help me..
Thanks

put device on charge overnight. then open back panel and disconnect battery connector. leave it disconnected for the day and try again other day.

Thanks
But how do I know if the battery is charging?
I mean the display isn't turning on or even showing any kind of notification.
Okay doing as you said.
And I hope this method works!
Crossed my finger.. !!!
(And one question , is it usual to have this kind of problem that I am facing now?)

yea it is somewhat common. and so far zenfone 2 is much easy to unbrick or recover comparing to other devices. well if you pur on charge after few minutes it will get warm. but if put on long and battery is charged then you will not be able to know as it will be cold. you can check battery voltage if it is above 4 volts means battery is more than 80 percent

Badly bricked zenfone 2 (ZE551ML) after 6.0 update

So after attempting to flash Asus 6.0 my device won't boot at all..
Like not even the Asus splashscreen, just some vibrate and shuts off.
If tried this solution but I can't get the iSOC driver to detect my device. It installs the Moorefield driver but it doesn't show as expected in the device manager.
All I get is the battery charging logo when I plug it in USB. And that is all. No other visual.
Is there any hope left to recover?
EDIT: I would expecting this screen but I'm not getting it. Maybe boot is not corrupted but something else? Anyway to enter that mode manually?

Hehehe I guess that post has better English which made the detection process much clearer then the source I quoted.
Tricky part it the device will not stay detected for very long but if timed right, it works! Got to fastboot and if reboot, at least I get hanging cables to repeat the proper easily
Dunno if you get the thanks since the solution came from an other user actually. Just kidding! you get all my thanks for directing me to the proper article

Zenfone 2 does not turn on

Good morning, I have a big problem in my Zenfone 2 and would very much like your help.
Yesterday in the morning he hung up, I thought I had downloaded but I tried to turn it when he called saw the battery was at 50%, I found strange but ok, then the screen locked and the phone started to vibrate and I had to off it. When I called, the battery was at 50%, was saying that the phone was connected and there do not leave sound and saying he was carrying. I thought it might be the rom and turned it on PC to back up and exchange of rom, only the USB no longer recognized the connection to the PC. Was saying that tava carrying, I took the USB and stopped "load" when I called he carried again, just not giving connection to the PC. Anyway I did not back up and changed the rom, he continued the same thing (I was in the AICP (LP) and put the RussiaNBear (LP)).
So I was following a tutorial that I had used before to repair another error (I could not post the tutorial link here, but it's on youtube: (Tutorial - Zenfone 2 unbrick / Restore (ZE551ML / ZE550ML) - In the Droid Will channel)), but I gave soft to do so because the part of the AFT (Asus Flash Tools) it does not recognize the phone, having to disconnect the usb and connect again, and then I screwed me, 'cause the uSB connection was not working. After a few unsuccessful attempts, it seems I agravei even more the situation because now I turn the USB cable pressing volume down and it goes in "Moorefield" and the PC identifies a good, open the xFSTK and can pass the DNX, but when you finish spending DNX the phone should reboot and a screen appears with the symbol of a uSB connection, but that's not what happens. I spend the DNX, the phone restarts and vibrates, there is the xFSTK waiting to pass the OS, but not USB screen appears, the xFSTK does not recognize the phone more in "Moorefield" and I can not do anything else on the device.
I have already connected the phone on another pc, I have changed the cable and nothing. I think it is the mobile usb, if not it would not recognize the first part of xFSTK.
Apologies if I have not posted in the right place, for my English (Google Translate) and the text size, only tried to leave everything well explained so that everyone can understand. Thank you very much, beforehand to help you and I really hope we can solve this problem.
Thank you.

ZE551ML keeps vibrating, won't start.

Hi everyone,
Yesterday, as usual, i plugged my zenphone to its charger, but it almost instantly turned off and won't restart since.
The phone keeps vibrating every minute as if it was booting, but the screen doesn't light up, nor the led while charging.
I've read a lot of thread with similar problems, which were solved by replugging the battery, but this solution won't work for me.
Here is what i've tried so far:
-Changing the charger/cable
-Replugging the battery
-Leaving the battery unplugged over night, then replug
-Leaving the phone rest for 8 hours
-Pressed every possible combination of button for 20 sec
None of the above solutions changed anything.
I don't think that it could be a battery problem, the phone shut down at arround 40% and my multimeter still indicates a voltage of 4.20V at the battery.
Hope you guys will be able to help me !
Thanks
4.2 means battery more than 80 percent. you seems bricked. use the following guide step by step read everything carefully. any question post there in the thread. please search around before starting new thread.

@Solasmeryl
Was you in M when you bricked ?
If you was and are getting 'continuing to os ' error in xFSTK .
Try this > in xFSTK
1) fwr dnx = your normal file you used before
2)Ifwi = try this >
http://www.mediafire.com/file/xjhv9gfiv5sn7xx/tmp_17491-ifwi_ann_a0-mofd_v1-ze551ml1929259488.bin
3) is skipped = per usual
4) OS = your usual posignbin you used before
If you get bootloader now , it will be 0094.0183 for M , flash M raw file.
Then you flash M raw file (twice) in AFTools, raw M = 4.21.40.184
First flash for approx 3 to 4 mins, where on-screen cmds pauses on "RESULT=OK" on phone.
Close flashtools , force close.
Open flashtools again , input raw , press vol+ (once) and serial now is corrected , flash till it boots into system.approx 8 mins
Notes..
If serial number is correct after xFSTK flash , you only flash raw once only. Flash Twice if serial is 0123456789ABCDEF
.
.
When connecting to xFSTK. Connect data lead.
Press power and vol-, press download , connect phone, release vol- and power
If fail , press vol + and power till first of two vibes , release buttons , hit download button in xFSTK at the same time you release buttons on phone , tricky but you can do it .
There's AFT and links to needed files in my unbrick thread in my signature , even a video showing flashing procedure
Fixed LINK , added M .184 ifwi for xFSTK
@timbernot
Hi, thank you for helping me out, i didn't though my problem could be a brick, but my symptoms are the same.
I was running CM 13, so yeah, the android version was M.
I tried your IFWI file but it doesn't seem to have fixed anything, except, the phone doesn't vibrate anymore now.
I don't know i just accidentally destroyed the vibration motor or if the IFWI file has anything to do with it.

Nothing to do with Motor i`m afraid
Battery dead , will be the main cause .
Leave connected to charger for a good few hrs :good:
Each flash in xFSTK uses approx 10% battery , more if you sit there watching it `continuing to os`
See my video in link -- the button process and connection -- i do it just the once , admittedly i have unbricked many zens and know exactly when to press dload in xFSTK :good:
https://www.youtube.com/watch?v=PmbRaJijIBs&feature=youtu.be
ps cm13 was based on LP mainly , only the latter versions and cm 14 had bootloader upgrades.
So return to original flashing files

Just FYI, if you were on cm13 official then your base was LP not MM. Even though it's an MM rom

Ok, so i charged up the phone, went back to the original file as suggested. Vibrations are back, but i still can't figure out how to pass the "Continuing to OS" error :/
Here is how i seem to understand the steps:
1. I Click begin download (which start the 120sec timer)
2. I press Power and Vol - for 4 sec then release
3. I Connect the phone to the PC, hear the windows "device connect" sound
4.Messages show up in xFSTK, sometimes errors, sometimes the download begins, and back to the "Continuing to OS"
5.The phone vibrates, the software attemps 20 reconnect then aborts.
I've also tried a lot of different combinations such as pressing power after plugging, not pressing power at all, etc (The software indicates 41 tries).
It just seems that the phone is completely dead :/
Thans a lot for the help, i really hope that i doesn't bother you too much by making mistakes !
Do you usual flash , soon as you see continuing to os Press power and vol + , at first of of two vibes - release and hit download.
Note , if only one vibe , re press and keep pressed vol+ and power immediately.
Do press download first like in the video..but you have to double click it to stop and to begin again at the exact time of releasing at first of two vibes
Ps , depending on pc speeds etc etc , it is wise to come off the internet , disable anti virus , clean pc from junk, c cleaner free is good and do a reboot.
Also , some people report it just flashing after hrs of failures by just leaving phone connected after a failure with xFSTK still open, then restarting flash after a good break of half hr plus

No change :/ even tho i've tried every button timing possible i guess.
I've noticed that pressing Power and Vol- before plugging in the phone always leads to an error. The only way to get to the continuing to os is by pressing these buttons while the phone is already connected, and then hit download.
Could there be any other software problem that could **** things up and that i forgot to mention ?

Can you ignore xFSTK for a moment
try this without being connected to pc either.
(A)Press and keep pressed power and vol+ . Does your phone vibrate (twice) ?

Well , somehow you gotta release both buttons and hit download at the same time at first vibrations of the two .
Do what you need regarding pressing power and vol- to connect initially . Then go about trying to get the above two vibes process while downloading . Be fast to double click download at the first of two vibes --
Thats it !
That is all anyone has to do :good:
One other thing to try is - just try power , on its own(like power off), press and keep pressed after initial connection download process, once it vibrates - release and -- go for the power and vol+ 2 vibe process again. Get ready to hit download !

If that doesnt work ^^^ i will begin to start asking questions about the settings you have applied
Double check this ->
(fast forward to 18:30 mins in of this video for settings to be modified in XFSTK re... changing GP over ride to 0x80000807 ) . Make sure you modified the correct CRC+ box at the bottom

Hi, sorry for the delay, i had a lot of work the past two days.
I've tried everything you said, double checked every parameter, and even tried the manipulation on another computer, but there is no change.
The weird thing is, that if i plug the phone into the computer, it gets detected, but there is no vibe, so no way to know when to click on download. I only get vibes on boot if it is not connected in USB.
Moreover, i don't really understand what you mean by " double click at the first 2 vibes", since the button gets "gray" after 1 press, and there is no way to double click it.
I'm sorry, you have put a lot of effort into helping me, but i really think that my phone may be more damaged than a simple brick :/

Suggests it will be USB board /port /cable :good:
Do the same again with data cable connected to phone but not connected to anything to rule out cable :good:

I'm not sure to really understand your last sentence ? Do you mean like removing the 2 power cables inside the USB ?
I've tried with different USB cables, and no change either :/

You can now only pray it is the USB board and not Mainboard , order a new USB board and a `new` Data cable, do not use old data cables with new board just incase your phones charge port has altered pins on either or both cables or data cable has changed pins on usb or vice versa :good:
ps , make sure it is a quality data cable you order too, some sell data when only a charge cable

bricked zenfone 2 ZE551ML

Hi,
long story short:
- worked for few hours, then refused to start, black screen, just vibrating
- bought it from my mom, by the time I got to see her, too late to retrun the phone. Seems like was a chinese import (I'm in France) so no ASUS support and too late to return it to seller...
- so tried to unbrick it following https://forum.xda-developers.com/zenfone2/help/thead-bricked-phone-updating-to-mm-tips-t3452785.
- Got the first steps ok (xfstk done)
- time to unzipthe stuff etc, phone turned off and PC rebooted for whatever reason
Where I'm at right now:
- nothing happens, not a vibration, not a detection in device manager, nothing... (I charged it)
-When plugged into computer, after a while, gets hot (more than battery charging, means CPU working like hell?)
Seems like dead for good? any hope to "reanimate it" at least to the fastboot to resume the precedure?
Thx much for your help, buying another one would be ... super sad and difficult
Cheers!
Try to flash using asus flash tool.
1. Download the lollipop raw firmware.
2. Asus flash tool
3. Drivers .
Now start the flashtool then select your device model from list then browse for the raw file that downloaded.
Now connect phone in boot loader mode.
Then click start it will take some time to flash. During flashing phone restarts at that time again boot it to bootloader mode.
You will loose total internal storage data.

that's the issue, can't enter bootloader mode (phone remains completely dead even if charged, no vibration, screen remains black etc)
thx anyway

Oneplus 5t black screen unbricktool doesnt seem to work

I've got a dead oneplus 5t from my son. It was not charging anymore.. So I've replaced charging cable and battery.. Seemed to work it was charging... However it doesn't boot... No logo screen screen stays black/blank.
Tried several suggestions on this forum to get into recovery mode, fastboot mode... But still nothing. Only vibrating works after a few seconds.
So tried to unbrick with OP5T_Unbrick_tool_dumpling_43_J.40_181105(OOS.5.1.7) and the qualcomdrivers..
I was able to install the drivers and I see they are installed in devicemanagement.. and an empty folder create for oneplus.
I charged the phone all night and was able to download the upgrade. It then says download complete and I tried to restart the phone..
Still just vibrating but nothing happens.. Seems like everything has vanished from the phone, no recovery, no bootloader, no files.
So how to proceed to get all the stuff on the phone? And maybe the displayscreen is dead, but how can I tell?
Also tried the SMT upgrade. Strange thing is the device and com port are seen in devicemanagement and active when I connect without volume up, but cannot start because it says When I try to use smt mode the program says: "This COM port is disable by user". With volume button up pressed and then connect, ledlight turns green but the qualcomdevice is grayed out in devicemanagement and it says waiting for device..
Any help is welcome. I am a noob in how to proceed on the phone however I have an IT background.
Spent already so many time figuring out .. maybe it's effortless and its for the trashbin.
Thanks in advance
SOLVED
I opened the phone again loosened all those tiny connections to battery, screen,charger, mainboard and re-attached them.. Somehow a connection seemed to be fitting allright as yI looked at it, but apparently wasn't :good:
