Zenfone bootlooping when booted to recovery. - ZenFone 2 Q&A, Help & Troubleshooting

When I write the command "reboot recovery" in adb (USB debugging was enabled), the phone reboots and remains stuck in the ASUS splashscreen. It reboots multiple times and then goes into the bootloader menu. I can't manage to go to TWRP. Adb says twrp flash was successful but I don't get the problem.
Please, its URGENT!

are you sure your bootloader is unlocked. if yes try flashing different version on twrp. better latest from twrp official website

i have similar problem , cureently i'd bricked my zen2 z008d . following instructions on xda finally my phone got unbricked. but after that my splashscreen is gone when phone booting to system and cant enter to recovery . bootloader its okay i can acces that and i can flash cutom kernel via fastboot.

Cannot flash and boot into TWRP on my Zenfone 2

Hi,
I'm trying to flash TWRP on my Zenfone 2 Z00A but it won't work. I cannot boot to TWRP.
My device is unlocked and rooted and I can flash boot.img, droidboot.img and stock recovery.img but TWRP IMG won't work.
After flashing TWRP using command "fastboot flash recovery twrp.img" and trying to boot into it nothing happens phone restart and boot to bootloader asking me to choose "Normal boot", "Recovery mode" "Reboot bootloader" ect.. and when I select "Recovery mode" phone restart and boot again to Bootloader not TWRP.
I also tried to flash TWRP using "Rashr" same problem not booting to TWRP.
Tethered CWM is working and I was able to boot to it but not TWRP
On the other hand if I flash back stock recovery and boot to it boots just fine.
What's wrong? Any idea guys?
Thanks in advance..
So, you've unlocked the bootloader or did you skip that part?

Yes it's unlocked.
When I flash TWRP via CMD using fastboot command it shows successful writing TWRP IMG file. Otherwise it will show permission denied if the bootloader is locked AFAIK.
The splashscreen is white which means the bootloader is unlocked. But I don't know why it's not working.
Device is CN version flashed with WW firmware.
TWRP App-based installation
I've also tried upgrading to twrp-2-8-7-2-Z00A.img from within the TWRP Manager app. It seems to download and gets to the "installing/verifying" screen, then dies after a minute or two. The phone is rooted and unlocked. But after about the 4th or 5th try, it worked.
Ok problem solved
It turns out there was a problem with the bootloader. I used the adb commands to unlock it and it was showing successful but some how it was not unlocked fully as it seems.
The splash screen turned to white after unlocking the bootloader so I thought it was unlocked. I even tried unlocking it many times and every time the adb results were showing bootloader unlocking success but it tuned out it wasn't unlocked fully.
Today I used the official bootloader unlocking App from ASUS and unlocked the bootloader. I flash TWRP again and rebooted to recovery and BAM ! it booted to TWRP

Hello, I have similar problem with my Zenfone 2 Z00A. Bootloader seems to be unlocked because of white splash screen on start-up, but I cannot flash TWRP recovery via fastboot flash recovery ***.img. The process shows no problems/errors but despite that no TWRP after reboot.
Can you explain how you found out that bootloader was not unlocked fully?

I don't know why but after 4-th or 5-th attempt TWRP finally loaded.
Hi, I have a similar problem with my zenfone 2 z00A. My device is not rooted. I tried to use the process described here.
Installation
Latest releases, tools and general information
groovyandroid.github.io
I tried bootloader unlock process with the app on my phone first, but after 4-5 times of use, it always came up with 'Network error'. I went with the 2nd part of unlocking bootloader to transfer TWRP imgae file. Now the phone is starting with a white splash screen and showing 4 options: Normal boot, Power off, Recovery mode and Restart bootloader. I have tried fastboot flash recovery twrp.img and fastboot boot 'twrp.img', but still can't get to TWRP recovery process.

Unable to flash custom recovery

Hi,
I have the Find 7 with the new display panel.
I wanted to flash the latest version of TWRP but failed. I do not know what I did wrong.
I can use adb and fastboot without any problem. When trying to flash recovery, it says there that the flash was successful but when I reboot to recovery, TWRP was not installed and the original Oppo recovery is still there.
The bootloader is unlocked. And I tried relocking and unlocking again but to no avail. Whenever I use the command "fastboot oem unlock", nothing happens to the phone.
I am currently on spectrum. I want to try other roms such as the lite COS 2.15 and also maxwen roms since that only those supports the new panel.
I am also trying to get root for my phone and it is impossible without custom recovery.
Thanks for any help.
I had poop loads of issues with getting custom recovery on my Find 7a. Eventually I used these instructions:
http://community.oppo.com/my/forum.php?mod=viewthread&tid=996
They work. Don't know if it's the versions of ADB or Fastboot or something.
Give it a go

I will give it a go when I get back. Thanks!
This is what a forumer from the official forum said and it works:
After you had successfully flash recovery via fastboot, you MUST NOT reboot the device. AFAIK, if you reboot the device it will restore the recovery back to stock oppo recovery.
So instead, you need to immediately press vol down & power button on the fastboot screen. Keep holding the button until you see the TWRP recovery screen. Hope that helps. Cheers!""

Unlocking bootloader erases data?
Mine wouldn't flash recovery. It said successful but I still had oppo recovery 1.2 and it only worked when I found the latest official twrp over version 3. after flashing, I disconnected usb and then held down power button to shut the phone down. It then was able to boot to twrp ok.
I used the latest one.

Recovery mode is'nt working anymore!! NEED HELP !!

Hi, I'm new to android rooting and flashing stuffs. I have Asus Zenfone 2 16gb version.
My frnd rooted my device and installed superSU (something like that) but the xmod app was not working, so my frnd gave me this Kingo root apk he told me that it will work. so I installed that kongo root..it says some files needed to be fix, so I presses ok..after the prosecco is done, I reboot my phone..but it stuck in loading. after that I'm finding solution to boot it back normally. I tried flashing new firmware which I downloaded from the asus website, but It failed in 48%, some one told me to flash TWRP recovery, so I flash TWRP recovery from adb sideload, after that I was not be able to go in recovery mode. I press for recovery mode...my phone restarts and again loads the fastboot or bootloader screen. after that I tried to flash other recovery image. but still I cant go in recovery mode. PLEASE HELP!!
You should not flash custom recovery with a lock bootloader. Unlock your bootloader first.
You dont sideload a recovery img. Go to bootloader, then enter this adb command
fastboot flash recovery (name of recovery image) .img
PS. Xmod dont work on intel based android processor. Correct me if Im wrong, Ive read that a long time ago.

Help with TWRP please.

I had TWRP 2.8.7.0 and wanted to flash a ROM that required 3.0.2.0. I found the directions here in XDA to flash TWRP with TWRP. https://www.xda-developers.com/how-to-install-twrp/ I installed the TWRP 3.0.20. image to recovery and almost instantly it said Flashed successfully. Here is where I messed up... I missed step 5 "fastboot reboot", and I pulled the battery.
Now when I go to recovery, I get the factory reset screens and click yes, yes and then black screen with tiny tiny [4 numbers to small to read] Fastboot mode started!
I've tried fashing in ADB, device is recognized, but after "reboot bootloader" command the phone reboots into bootloader mode, then I get "waiting for device" after "flashboot flash recovery twrp.img"
It seems now that when the phone is in bootloader mode, ADB does not recognize it anymore...
Somehow, I also lost root and although my phone still boots up okay, I haven't been able to get it rooted again and so I can;t flash TWRP with the official app.
I running the Tesla ROM 7.1.2 RC

trying to boot into recovery mode and getting "no command"

trying to root my device.

am i doing something wrong?

unlock bootloader and retry that step untill you can get custom recovery.
I mean, you may need to reflash recovery image many times.

i got it . you have to go straight into recovery mode right after you flash it , ie dont reboot phone first .
