Alternate method to get the phone back
Well, out of desperation, I did the following:
1. Keep fastboot and twrp recovery ready
2. Type in the fastboot recovery command in prompt
3. Press volume up and power button.
4. As soon as I get the fastboot screen, quickly connect your phone to the PC
5 As soon as you hear the new device connection music press enter on the command prompt
steps 4 and 5 should be completed within 5 seconds ?
Repeat steps 1 to 5 couple of times until you get the timing right.
Finally it worked for me on third attempt and I got my phone back ?
Once it booted normally I went back to the recovery, wiped the caches, ran diagnostic and repair disk tools nothing came out of the ordinary.
Hope it helps anyone with same problem..

yesterday i unlocked the bootloader, and used ADB and FASTBOOT to flash TWRP 3.0.2 and then rooted by flashing superSU v2.76
the phone was still S-on
i attempted to modify the buildprop file and used TWRP to mount system and copy the file over to /system/
i did have other things ticked as being mounted, like /data and one other partition that escapes me now.
anyway, i copied the buildprop back and used CHMOD755 but thought choosing 644 would be better so i choose CHMOD but entered 0644 as it was asking for 4 characters. after hitting boot system the phone just went black, trying to boot into bootloader mode now doesn't work, nothing happens. the only way i get any sign of life out of the phone now is by holding volume up and power. then the phone will boot for about 5 to 6 secs before going black screened again.
so i can't boot, cant enter recovery or bootloader.
usb debuggung was ticked previously but i'm not sure i even have a working rom now. ADB fails to find a device and trying
Code:
abd reboot bootloader
just brings
Code:
error: device '(null)' not found
am i totally screwed ? or is this something i can fix ???
help needed...
Connect to PC so you can hear connect/disconnect sound.
Press & hold power + volume up buttons to force reboot, once you hear the disconnect sound on PC, release both buttons and quickly press & hold volume down button. This will take you to hboot, select recovery and restore your backup or install ROM zip

connecting up to PC i don't get any "bing bong" sounds at all. if i try booting with volume up and power while connected to PC i still don't get the bing bong, quickly switching to holding volume down as you suggest doesn't stop the phone going back to black screen.
HEEEEELLLLP !!!!!
EDIT: additional info
the phone has been this way for a few hours now and twice in that time the phone has started booting up by itself (without me touching it), only to go back off again the same as every other time...
EDIT: after leaving the phone to go nuts all by itself and let the battery run down and recharging it, I was able to get back into bootloader mode and recovery to restore a backup.
I am now happily running GPe MM, and about to test out ElementalX
Hello
I was updating from a M version to another M verions. But I had to use the temporary recovery method.
This is what I was doing but didn't finish properly
Requirements:
1. Unlocked bootloader
2. TWRP for Z00A (Download | How to Install TWRP)
Unlock Bootloader on Android 6.0 Marshmallow ZenFone 2 ZE551ML/ZE550ML
Download tool (Download Here)
1. Extract it and connect Zenfone 2 with laptop/pc
2. Click unlock.bat will automatically detect whether the adb or fastboot mode, and then reboot into bootloader
3. Will appear on the screen to unlock the success of mobile phones after five seconds will reboot, then hold volume up the phone automatically re-boot back to bootloader.
4. If you missed the previous step, press the power button for 10 seconds off, then press the "Volume Up" and hold the power button to boot into bootloader.
5. After the phone has successfully re-enter the bootloader, click restore.bat on the computer, where the restore refers to the restore Android ifwi 6.0 otherwise Android phone can not enter the system.
6. The phone will reboot and restore white on black ASUS logo screen, and then enter the Android system.

I extracted and connect my zen2
Ran the unlock.bat
The phone entered the bootloader, flash his things and boot again but on the white screen
Then I had to hold power button 10s to turn it off and turn it on again
Entered the bootloadr by holding Power+Vol UP then to recovery.
At this time I just used the recovery as I usualy do, Wipe everything, cache, data, etc.
Connect to the PC, put the new UL-Z00A-WW-4.21.40.184-user.zip there and flash.
BUT now that comes the problem. I select the option to boot it after finish flashing.
So obviously I didnt finish the steps mentioned on the quote above.
I didnt ran the restore.bat before reboot into system and now All I see is black screen.
I've tryed some steps of those tutorials for briked phones but My computer can't see the device for long enough
http://forum.xda-developers.com/zenfone2/help/thead-bricked-phone-updating-to-mm-tips-t3452785
I try to do those steps but I'm stuck on this part
now back to the Zenfone 2, hold power for 20 seconds to shutdown, 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 successful.

My phone doesn't boot even on bootloader. It just vibrate twice and then nothing happens.
On my device manager I can see the "Moorefield" but only for a brief moment. when I try to turn on the phone then it immediately disapears and repeat this process (Vibrate twice, long preiod doing nothing and still black screen, then vibrates again twice, repeat)
Any suggestion?
Thanks in advice

Sadly, no.

Let me know if you find something
You have tô unbrick your phone. There are some tutorials in the forum
I am using the Z008D variant of the Zenfone 2.
I had bricked my phone 3 times and the guides that had helped me are:
https://forum.xda-developers.com/zenfone2/help/thead-bricked-phone-updating-to-mm-tips-t3452785
https://forum.xda-developers.com/zenfone2/general/guide-brick-soft-hard-bricked-zenfone-2-t3284256
I too had the same problem the first time I unbricked my phone. The moorefield device would show up briefly in device manager. It is stated in the guide that you had to press power+vol down when connecting the phone to use xFSTK. I googled and found that you had to actually press and hold the vol down button only and then connect the USB cable, then release it when the moorefield device is detected.

Hold all three buttons down till drop out to power off.
Hold down up and power up key same time.
Once you see on screen with image?
Release the power key..
Still holding that up key...
If you see that boot screen change release.
See if that works.
Hold all 3 till power down.
Make sure you if you can. Pop out the battery and pop back in if possible.
Then hold the power and that other key.
Once you see or feel something release the power key. Then once anything comes up on screen keep holding the up key for like 6-7 seconds or until u see something.
Another way is to boot into android and use adb to make the phone go into recovery reboot. Also try a program if you would like to reboot into recovery.
There are lib files and some places that reference that key layout in boot.img did you possibly do anything to change anything?
Nothing happens without reason.
I hope this information can help you.

Not work
I think I figured it out:
1. Boot up normally
2. go to Settings-About Phone-Device Info and repeatedly tap onto build number
3. go to Settings-Developer Settings and enable OEM unlocking and adb debugging
4. on your pc, download adb and fastboot
4.5 plug your phone into the pc
5. if a window on your phone pops out click ok
6. on your pc open cmd and go into your adb and fastboot folder
7. type adb reboot bootloader
8. type fastboot oem unlock
9. hold VolumeUp-VolumeDown-Power until the menu changes
10. unplug the cable and pop out the battery
11. put the battery back in and plug your phone in
12. hold VolumeUp-VolumeDown-Power
13. When you see the lenovo screen stop holding power
14. when you see No Command screen stop holding VolumeUp-VolumeDown
15. Press VolumeUp-VolumeDown-Power 2 times
16. You are in the recovery mode and you can access the bootloader from there
This is my first time attempting to flash a ROM but I haven't even got as far as getting to TWRT. I have followed these instructions...
wiki DOT lineageos DOT org SLASH devices SLASH ether SLASH install
....up to flashing TWRP onto the phone. Attempting to reboot into recovery per the next instruction, the phone's screen hangs on:
Your device has been unlocked and Nextbit OS can't be checked for tampering.
Your device will continue booting in 5 seconds.
Fine, except it does not continue booting. The screen is frozen, and neither pressing nor long holding either the power button or either of the volume buttons does anything. `adb devices` in a terminal does not see the phone, so I can't force a reboot that way. What's my next step?
Solved
The solution was easy, though it took a while to find it. Long pressing vol down + power for several seconds took me to fastboot, and I was able to continue from there.
how did you continue cuz i am not able to restart the device or access it from ADB

the same problem, did you fix it?
Sometimes, you need to press vol down + power for about a minute to reboot.
I have TWRP installed, and have managed to run it a few times. Now I cannot start TWRP at all.
From off, if I switch on, the following happens:
1) Screen with Samsung Galaxy A70 - Secured by Knox
2) 0.5 seconds later another screen, "this phone's bootloader is unlocked and it software integrity. .." and "press power key to continue..."
3) 5 seconds later, same screen as (1)
4) 3 seconds later, red letters "this phone is not running Samsung's official software"
5) 3 seconds later blank screen with "samsung" and then booting to android.
In my experience I have to flash twrp every time I want to use it( I don't know the reason but I couldn't fix it ) , for booting twrp on the other hand I turn off the phone first, then I press power button+volume down until the "this phones bootloader..." screen appears, here is the tricky part, you have to quickly let go of these two buttons, press power button, let go of the power button (after the warning disappeared) and then press volume down button (and hold it) until twrp logo appears, this happens really fast so you may need to do it a few times to get used to it.

Yes, same here, the only time I have managed to run TWRP on this phone, is right after a flash.

Power off the device, plug into a pc, wait for it to start charge, hold vol up and power till it turns on. Wala boots to twrp. If you have magisk installed,you can use the reboot option within magisk.

Samsung changed how to enter recovery on Android 11. Power off device, plug into pc, wait for it to charge, then hold vol up and power till it turns on. Alternatively, if you have magisk installed, use the reboot options within magisk.
I did that. Thanks!
But it has gone to:
Android Recovery
Samsung /a70qxx/a70q
11/RP1A.200720.012./A705FNXXUB5DVB3
user/release-keys
Use volume up/down and power.
Reboot system now
Reboot to bootloader
Apply update from ADB
Apply update from SD card
Wipe date/factory reset
...
...
...
Where is TWRP? It seems it's gone.

That's because you're not installing it properly go back to my guide and follow it exactly and stop listening to these other people. I've been modding this device since it first came out with Android 9, I know every inch of this device. You're getting confused by what other people are telling you

It fails here, on this step. After successful flash of recovery.tar, power + vol down to reboot, cable still connected, nothing you can do now can bring TWRP up. The phone boots into Android.
EDIT: I think I have now got it. I will update in a few mins.

After successful flash of recovery.tar, power and vol down to reboot, as soon as the phone screen goes blank, immediately release all keys and press and hold vol up. Must be as soon as screen goes blank. The device will then reboot twice and land you in twrp splash screen. You must hit vol down and power after successful flash then when screen blanks, vol up. If you miss this step, twrp will not hold and revert back to stock recovery.
Here is the notes I made today:
****************************************************************
INSTALL + START TWRP
phone is off
press up + dn
insert cable
go into download (press up)
ODIN 3.14 + AP:tar(vbmeta.img+twrp.img), auto reboot off, press upload
when it succeeds, press dn + pwr until it reboots
then quickly up + pwr until it starts (no need to hold down)
this starts in TWRP
from powered off
press pwr button
goes into twrp or android(system) -- depending on what was used last time
if we used reboot->system last time it will now **Always** go into system!
to go back into twrp:
switch off
power cable until charge
pwr + up until it starts
****************************************************************
The above means that you CANNOT go back to TWRP unless you have a cable and a PC near by.
