[Help] I cannot get my zenfone 2 into recovery mode.

I've tried everything I could find with a google search but I haven't found anybody with a similar problem. I cannot boot into recovery mode as every time I select recovery mode I get sent back to the fastboot screen. I can use normal boot and my phone starts up fine but choosing recovery mode just brings me through an endless loop of going to the fastboot screen. Anybody know a way around this?

It usually occurs simply because it cannot boot into recovery. This may be due to accidentally wiping the recovery partition, thus having no recovery to boot to at all, or that you flashed an incompatible recovery onto your device.
Fret not, just a few simple commands should get your phone back alive and kicking.
First, download the recovery.img (ZE550KL) at https://drive.google.com/open?id=0B6QXDUz9wzc9bUZaOHJsTzBhcVk
Then, boot your device into recovery mode.
Once done, type the command, in order,
fastboot flash recovery recovery.img
fastboot oem reboot-recovery
Do take note that you would need to have ADB tools installed, a reliable connection to your computer, ASUS drivers in order for your device to be detected, and some knowledge on where to place the recovery.img in order for the commands above to work. If you need any help, please feel free to ask. Also, since you did not state the variant of your device, I had put the ZE550KL recovery.img instead. If your device is of another variant, please inform me immediately and I will get the recovery.img up for you.

Thanks so much, this worked. I have a ze551ML but I had a stock recovery already on my drive. I've been trying to install the twrp recovery for the last two days but have been completely unable. Although the "fastboot oem reboot-recovery" failed as adb didn't recognize the OEM remote. Any idea why the most up to date twrp recovery has not worked in the least?

You need to unlock the bootloader first. There are plenty of guides online about how to do this, unofficial and officially. Also, there's a dedicated forum for your device variant, named "ASUS ZenFone 2"
This forum here is for the Laser variants.

sudden bootloop (can't get into recovery mode) n I didnt update to android 7,

so there I was in my car, my phone plugged in via aux cable and playing some music
suddenly I notice the music stops and my phone goes into a reboot,
I was using a pure nexus rom on marshmallow ( the latest marshmallow one i believe) and had xposed, and sometimes my phone would randomly reboot,
it was annoying but I could live with it
so i thought it was having another one of it's moment
but now it doesn't actually reboot,
my phone is stuck in a reboot loop and I can't even get into recovery mode, (I had TWRP installed and could boot into it numerous times before this)
anyone have any ideas?
I've installed twrp via fastboot
but I can't use the adb command to boot into recovery since device is not found,

Hi... You can't use adb commands while in bootloader... Only fastboot commands. Use the volume rocker till you see recovery mode displayed and press power button. If it still bootloop, try formatting cache and data with fastboot in bootloader and reboot in recovery again. If it still bootloop. Finally try fastboot flash a stock Google image. If none of these steps work, your phone is probably dead and you'll have to try to RMA your N6P.

Fastboot flash-all.sh is for Mac computers so presumably you have a Mac. Flash-all.bat is for windows. You need to unzip the Google image and move everything into the same folder where you have the fastboot program. Just open a command prompt window inside that folder and type the command. That's how I do it in Windows. Presumably the process is similar with a Mac. You will still have a zipped archive after you unzip the Google image but you want to leave that one as is. So far flashing flash-all.bat has gotten me out of every boot loop I've gotten into on my 6P but my phone never spontaneously bootlooped. I was always doing something (updating a rom, trying to restore a nandroid backup) that resulted in a bootloop. The fact that your phone boot looped without warning is probably a bad sign. If you still have warranty I would try to flash stock and see if you can RMA phone. If that isn't possible you might want to try staying on stock or using a different rom and seeing if the random reboots still occur. Good luck.

Well that really sucks. Sorry for your loss but it is a long running phone failure problem. I'm on my second 6P because this. Even worse to me is the fact your were running almost the exact same setup I am now. I refrained from running 7.x.x to try and minimize my chances of another BLOD so now w4on knows what to do. Lol

Help please can't see my phone in adb

I've had my Essential two weeks i was on 8.1 beta.Today i unlocked the boot loader.Then installed twrp while in twrp i side loaded magisk.I went back to fastboot then hit start .The phone just went into a bootloop.I Was able to go back to twrp 2 times but now i can't get back to any type of recovery.I Can get back to fastboot mode ishow all the info and secure boot says yes and device state unlocked.My pc see essential phone fastboot in the device manager but i can't get adb to see it .Can anyone help me ?

forgot something
looks like i skipped this part . Once you're in TWRP, install the stock boot image and then the Magisk/SuperSU zip.Is there anything i can do?

adb only works while phone is booted into system so nothing wrong there. If you're in the bootloader menu where you see that the status of your device is unlocked then you're already in fastboot mode. Just flash twrp again and the sideload stock 8.1 beta boot image (you can probably find it on xda), sideload magisk too. Go into install and press flash image file and find the stock boot image and then go into install again and change to flash .zip and flash magisk. After that, reboot into system.

WOW thank you so much'

No problem. Thank you very much for the donation, that was really kind of you. Hey I'm sure you'll get the hang of it before android P drops. you did figure out what went wrong all by yourself so get a hold of the right boot.img and the rest is exactly as how you did it in the first place but flash the boot.img before magisk. Let me know if you want to give it a dive again.

I'm on 8.1 boot loader unlocked and ready to try to root again .Thanks for the help

This is the closest thread i could find to what is happening to my PH-1.
Like videodave1 I 'was' running the latest stock 8.1 and have my bootloader unlocked. In trying to root the phone I did this:
flash boot flash boot twrp.img
adb shell twrp sideload
adb sideload magisk.zip
All installations went well, but when trying to reboot from twrp it forced me to install the app. After that the phone went into boot loop.
* Note how I didn't sideloaded the Oreo 8.1 image before magisk.
By pressing all 3 buttons I can get the phone to reboot and releasing the volume up I can get to Fastboot. Just volume down and power doesn't work.
The problem now is that adb and fastboot no longer recognise the phone. adb devices just gives an empty list and fastboot only shows < waiting for device >
Trying to go into Recovery mode doesn't work either. Power off doesn't work and Restart bootloader, well, restarts the bootloader.
It might be relevant to mention that I'm running adb and fastboot from Terminal in a Mac and that this is my very first and frustrated attempt to root any phone.
For reference this is what the FastBoot Mode brings:
PRODUCT_NAME - Mata
VARIANT - OPENUS
BOOTLOADER VERSION - mata-aad8ac4
BASEBAND VERSION - 2.0.C4-M1.3.1
SECURE BOOT - yes
DEVICE STATE - unlocked
I might have to just resign myself to the ordinary land of unlocked full stock phones
Thanks very much

I might be missing something hopefully obvious here. How can I flash twrp again if I my computer can't see the phone. With the USB phone plugged in and in the FastBoot screen I enter into Terminal:
fastboot flash boot twrp.img
and I get:
< waiting for any device >
How do I flash it from the FastBoot screen? BTW, going to Recovery mode just hangs at the Essential logo.
Thanks

Thanks Arju. If you are referring to the FastBoot menu where you can use the up and down volume keys to select Start, Restart Bootloader, Recovery mode and Power off Yes, but not much else unfortunately.
If I select Recovery mode I don't go to the screen with the blue buttons from twrp.

What you need to understand is that twrp will not stick after you flash it. This device does not have a recovery partition and that's why you replace the boot partition with twrp and while you're in twrp you need to flash the boot.img back and whatever mods on top of that such as kernel etc.. If you flash a rom then it will replace the twrp with the boot.img found in the rom zip.
So now we need the computer to recognize you device. Could you unplug the cable and change the usb port on you computer. connect your phone while you're in the bootloader menu where it says start on the top.
The use use fastboot command: fastboot devices
See if the computer recognizes you device.

Can't install TWRP on OP6T

Hi - I am trying to reinstall TWRP on my OP6T after upgrading to OOS 10.3.0.
I am running Minimal ADB and Fastboot v1.4.3 on my Win10 PC. I have connected my phone to my PC, and entered Fastboot mode. The OP6T is detected when I do a fastboot devices command.
Next, I try doing a temporary Recovery Mode boot into TWRP with a fastboot boot twrp-3.3.1-1-fajita.img command. This is where I run into a problem ... While the Minimal ADB and Fastboot window says that the TWRP image was sent to the OP6T, I am still stuck on the Fastboot screen, and the phone is locked up and doesn't reboot the image.
What is going wrong?

Thanks, @jp0469! This helps a lot!
Just to be clear (and to get to a successful conclusion without a bricked phone), I won't be installing a TWRP installer ZIP file after booting into this TWRP image (The old style method), but instead installing the same TWRP IMG file as a "Recovery RAM Disk", correct?

Need a little more info before you proceed.
I know you said that you're currently on Android 10.3.0

I was rooted with Magisk, but that got lost when I did the 10.3.0 update. Definitely planning on TWRPing and rooting again, as long as it's safe.

Stick to good old ones...
Once booted in twrp via fastboot flash the installer zip. It has always worked and will always. Always latest version. And flash Magisk after.

Put the latest Magisk zip and TWRP installer (zip file) on your phone's internal memory if you don't already have them there. Now you can fastboot boot the TWRP img file (Q version). Next flash the TWRP zip to permanently install TWRP into recovery. Reboot back to recovery to make sure it worked and then flash Magisk to re-gain root.
Reboot

Thanks, guys - The only reason I asked about the alternate "RAM Disk" method was because it was listed as the installation method by the developer on the link that @jp0469 provided earlier.
I'll try the old-fashioned method, since y'all say that it works OK.

I always install the latest directly from Google. There is a link on this page to the latest version of Windows ADB and Fastboot. Just unzip the file you download into a directory of your choice.

Everytime I try to boot twrp It says waiting on device. What's that mean

After doing the fastboot boot twrp-3.3.1-30-fajita-Q-mauronofrio.img in Fastboot Mode, I installed twrp-3.3.1-30-fajita-installer-mauronofrio.zip in the booted TWRP Recovery Mode, and everything is working fine again.
Thanks, guys!

I'm newish to rooting I've rooted other phones but that was back in the good old days where it wasn't complicated. I am running a T-Mobile phone converted to international with bootloader unlocked

Google Pixel 3a (sargo) brick - error boot prepare

Hi,
Today I wanted change my recovery. I had the Lineage OS recovery, but i was trying to install the twrp recovery.
So, the guide of twrp says that you should boot the twrp via fastboot boot twrp.img and install via the booted twrp. But I mistaken the command and I wrote fastboot flash boot twrp.img, I tried to reboot and the device booted himself in fastboot with the enter reason "error boot prepare" and I can't boot into the system or recovery.
I tried to flash the official image downloaded from the Google Developers website, but when i run ./flash-all.sh, console get stuck. I waited for about 15 minutes but nothing. I tried even the official Android Flash Tool but after 10 seconds it says "Your device stopped responding. You may have to select restart in the bootloader menu in order for it to be recognised again."
Does anyone know how to help me? Thanks in advance.

Yes, I wrote in the post, I tried both the command line tool and the chrome version. Btw i'm on linux

Okay so, I fixed.
For anyone who will have this problem you just need to flash official Android 9 and next Android 10. Only with Android 10 you can use fastboot flash boot recovery.img (you can't use twrp in android 10 with the Pixel 3a)

It depends if your pc were authorized, if it was, you can use fastboot to flash the stock version of Android 9, just running the flash-all(.bat) script.

I'm not certain I understand what you mean by PC authorized? I'm using a Windows 10 tablet. When the phone is attached to the computer it sees it as a device that can be disconnected through USB.

I just had an encounter with this. I was rooting my device (Pixel 3A) and messed up my partitions through accidentally attempting a downgrade which broke all my ****. I was unable to easily reset this device to factory, so it took me several days to figure out and root. I'm getting better though as a hacker, because a year ago this would have taken me a month.
I was able to enter recovery mode (lying down Android, NO COMMAND). From this recovery mode, adb devices -l recognized my device, although I was unable to get a shell.
At first, ADB was telling me the device was authorized, but I messed with a bunch of other stuff (tried to flash a bunch of different partitions and monkey around in general trying to install Magisk) and then ADB started telling me it wasn't authorized when I used devices -l.
Once it said unauthorized, I was unable to issue the device any commands with ADB, so I just used hardware keys to get into recovery mode. From there, I selected OTA update, and it got into sideload mode. At that point, I used adb sideload with the OTA package that I downloaded here https://developers.google.com/android/ota
^^^ That operation did successfully restore my device to factory
This following guide here describes the details of how to use hard keys to enter recovery on this phone (don't download anything from there tho, and make sure your adblock is on)
How to Hard Reset your new Google Pixel 3a [Tutorial]
In this article, you will learn how to start your Google Pixel 3a up into the Recovery Mode and perform the Hard Reset to make it work perfectly again.
thedroidguy.com

I just wanted to say, I've been wrestling this hardbrick for a couple of days with my Pixel 3a.
I've finally overcome it by sideloading the most recent OTA update after using a hard key combo to get into recovery mode. The hard key combo is hold Power Button, tap Volume Up, then release both. Then, all you need is to use the command:
adb sideload <OTA.zip>
^^^OTA wasn't the actual filename though, you can download OTA packages for Pixel 3A here: https://developers.google.com/android/ota
the OTA binaries are NOT the same as the factory images, which is here
Factory Images for Nexus and Pixel Devices | Google Play services | Google for Developers
developers.google.com
Sideloading the OTA package brought my phone back from only having fastboot and recovery mode, even when flash-all.sh from the official downloaded firmware failed. Now I know how to undo damage that I cause by rooting this thing. Since I sideloaded newest firmware, it was also like applying an update. I easily got root after that, and I've logged the process. I'll make it into a guide soon

I'll just note that if you accidentally flashed the TWRP boot image instead of simply booting into it, I believe all you have to do is flash the stock boot.img to fix the problem. Obviously you can sideload the entire rom image, but that shouldn't be necessary.
Using the Windows computer (or whatever computer you are sending ADB commands from), download the full stock image directly from Google. Unzip it and then upzip the folder inside. You should find the boot.img file inside that folder. Take that file and then flash it to the phone using the normal ADB command: fastboot flash boot boot.img
While I haven't tried this myself recently, it should work in theory. The command "fastboot flash boot twrp.img" flashes the boot partition with a non-working twrp image, so replacing the faulty image with the stock boot.img should fix the problem.

If I did the same I would first attempt to manually put device in bootloader/aka fastboot mode then fastboot flash the stock boot.img , sudo fastboot flash boot boot.img --slot all
I only read the op (first post here);but I betcha that would have worked. Then sudo ./flash-all.sh and let it do it's thing.
