Can't enter fastboot mode Vol - Power - ZenFone 2 Q&A, Help & Troubleshooting

If I hold volume button down while pressing power, it does nothing. Just stays totally black. Held it for 1 min straight. Release the volume button and just hold power and it turns on fine, but can't enter fastboot mode. Have tried now 5 or 6 times. Any ideas?

I have the same issue....However I can enter fastboot via adb

Okay. Was able to do the same, but "adb fastboot recovery", but no option to update from SD. It automatically tried looking for "MOFD_UPDATE" when entering recovery. So I renamed the download from Asus to MOFD_UPDATE, but ran into other issues (CN build not allowing WW update).
Are you getting option to update from SD in recovery?

It should be volume up + power. When the phone vibrates, release power but keep holding volume p.

Okay. I was following from here http://forum.xda-developers.com/zenfone2/general/guide-how-to-update-flash-asus-zenfone-t3084727
I tried volume up too, but found it needed to be released, at just the right moment, then re-pressed again. Otherwise it just powered-off again if holding straight until after the quick logo flash. I found I needed to release during the logo flash, wait a second, then repress and hold. I know, sounds strange, but I've reproduced it many times.
Anyways, OTA shows no update available, even though there's clearly an update to both CN and WW on Asus site. Trying to flash WW gives me build prop error because SKU is CN (but current ROM is WW). Strange situation. Haven't tried manually flashing latest CN yet.

Hye can help.my Asus zoovd can't enter to recovery mode and suck.but fastboot mode can enter. Have idea?

Hi bro did you find a solution to boot your phone into fastboot mode. I have the same issue and i need help

[Q] Can no longer get to bootloader

Hi,
Fairly new to android scene. I recently rooted and unlocked the bootloader. I'm now trying to get CWM ... but I can no longer get to the bootloader so I can enter fastboot mode. I hold down the power and the down vol key but nothing happens, after a while it just restarts the phone.
Edit: I got into bootloader by holding down vol down and power for about 5 seconds then let go of the power button and then tap the power button a few times.
Did you disable fastboot? If not it's under settings -> power.
Then try again, hold both buttons down until it appears.
I disabled fastboot. Sorry forgot to mention that in the first post. Right now I'm trying to set up ADB and see if I can do it from there, but I'm having problems doing that too.

Are you using the correct steps to enter recovery mode?
1. Power off your phone
2. Press and hold the volume up button, then press and hold power until the phone vibrates
3. Let go of power ONLY
4. Use volume keys to select recovery mode on the next screen.
5. If you have stock recovery, it will say "Error". While holding power+Vol down, press and release Vol up.

help Zenfone 2 black screen, no bootloader or TWRP vibrartes twice and nothing

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.

How to reliably start TWRP

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.

Question Blocked while rooting

When I was going to root my phone, I must have taken a wrong choice on the download screen (I can't remember what) because it got to another screen like the attached screenshot over this text: "Press power key to continue", but pressing that key does nothing. Every time I start the phone, that screen comes up for about 10 seconds, and then it boots in an apparent normal way.
The same screen of the screenshot keeps coming back when I press the keys for download mode (Volume Up + Volume Down + Power). Pressing the keys for recovery mode (Volume Up + Power, from off) nothing changes. However, I pressed that keys for over 2 minutes and the phone entered in recovery mode. Then, I could wipe everything and rebooted, but the problem persisted exactly as before.
I can't get to the download mode, so I can't download any ROM. What can I do?
Just confirming, you've plugged in the usb cable before pressing the buttons to go to download mode?
Might also try using ADB commands to get to bootloader...
