Hi Guys,
I have been give a Zenfone 2 which cannot reboot into stock recovery or any recovery, basically at the bootloader menu when you select recovery it reboots and goes back to the bootloader menu.
I've installed Rom Manager and it says both TWRP and CWM are installed.
So I believe this has multiple Recoverys and it basically cant use any, I have attempted to flash it back to stock but it wont again even let me into recovery that way.
I was rooted but I fully unrooted it to see if this would make a difference but it made no difference.
The bootloader says unknown and the screen is black on start with the Asus logo so would that suggest it has not got an unlocked bootloader either if so I believe the person who owns the phone tried to flash the untethered version of TWRP without having this unlocked ?
Any ideas how to get this back to stock and a recovery working ?
Thanks
Have you ever tried flashing stock fastboot?
I think the guide of "changing phone's SKU to WW version" can do the trick. Doing this can have official fastboot and recovery flashed on your phone.

Today I have faced a strange situation, I installed TWRP (after unlocking the bootloader) on my OP3 as soon as I received the device then I flashed custom ROM by @Grarak http://forum.xda-developers.com/oneplus-3/development/rom-unofficial-cyanogenmod-13-t3399089.
After using for some days I decided to give Oxygen OS another try, so I wiped the cache,data,system and Flashed full OTA provided by @namanbhalla https://forums.oneplus.net/threads/...ficial-oxygen-os-roms-and-ota-updates.450783/
Every thing went smooth but after starting up I wasn't able to goto twrp, for some strange reason twrp was automatically replaced with stock recovery. OK, I decided to reflash twrp, but bang! after so many flashing I wasn't able to boot into twrp, still there was stock recovery.
Solution:
1) fastboot oem unlock (re run even if it says already unlocked)
2) fastboot flash recovery twrp-3.0.2-0-oneplus3.img
now TWRP is installed.
I not Android Developer and cant guarantee above will work and wont harm your device. Try at your own risk.
that is all not needed, i have had this happen to me multiple times reflashing Stock and Stock recovery replaces TWRP, all u have to do is boot up to fastboot mode and flash TWRP, do not reboot, use Power + Vol + and when the Unlocked bootloader screen comes up press the VOL key and click recovery and TWRP is back. no need to do the unlock bootloader again, unless u unchecked it, just make sure it is checked when flashing the Stock rom again or u can just use flashify if u rooted stock before the recovery got replaced somehow, i have even had this happen on FreedomOS 3.2.1
I tried booting my HTC ONE M8 into recovery mode and I got a warning sign on the screen which stayed for about 20 mins before the phone automatically rebooted and it's working fine, does this mean that I don't have a working recovery? And how can I fix it. Screenshots attached.
That's a working stock recovery. Why do you need to boot to stock recovery ? You won't be able to install custom ROM with stock recovery, you need custom recovery like TWRP installed first.
BUT first thing you need to do is update your current firmware to at least 4.21.512.4. If not, no use to install TWRP as most custom ROM won't work on your current firmware.
Go back to your thread and read again the link given to you. You won't accomplish anything without reading

So, I was attempting to root my phone(CanvasA1- 4GB) today running stock android marshmallow(6.0.1) , I successfully unlocked the boot loader in fastboot using adb, after which I flashed TWRP recovery, Which was successful but then, When I rebooted into recovery, I saw my old stock google's recovery running , I tried 2-3 more times flashing the recovery in fastboot but the probem was still the same :crying:. Then I came to know that we have to flash a special type of boot img of some 17.5mb approx, When I attempted to flash this "boot" image, I received an error saying file size too large, Hence I couldn't flash it, I am still running the stock recovery, With my bootloader unlocked, I need to root my phone, Please help someone, Thanks in advance .

You can search for Android One Toolkit. Iwas encountering the same problem but this app solved my Problem.
Sorry dont have Link for the Same.
Same here. I unlocked the bootloader successfully and flashed TWRP recovery. But it shows system/default recovery only. Now stuck in bootloop.
Tried clearing cache/date etc. nothing worked. Don't know what to do.
So im on V4.21.40.191 and no matter what recovery i flash it doesnt work, i cant get into recovery from bootloader it just reboots itself to bootloader. it goes in recovery only if android is running and i send it "adb reboot recovery" command but that goes to system recovery, i've tried flashing different recoveries but non worked, all recoveries were flashed fine, no errors, flashed them in bootloader through "fastboot flash recovery xxxxx.img" command!
Please help, as im unable to root it, also if there is a non recovery way to root ZE550ML 6.0.1 then do tell me that too!
Thanks!
EDIT: i found out what i was doing wrong, my bootloader got locked during something nd i didnt knew, unlocked it again nd everything works fine now!
I was running an unlocked one plus 3 on OxygenOS 4.0.2 (Android Nougat) and have TWRP installed. As 4.0.3 got released yesterday, i tried installing it today but i accidentally hit install on the OTA update setting which caused my phone to reboot. Now my phone won't boot into the os, i get a black screen after 'powered by Android'. I tried getting into Recovery however i get the same response, a black screen. I do not think it is hardbricked as the Fastboot still works and when i go into fashtboot it states that the OEM is 'unlocked'. I have personal data on this device pls can someone help. I do not know what i should do> How do i boot into recovery without crashing?
Is it possible to install twrp again with the PC? I had once also the same problem, install it again and after that it booted again into recovery.
Just install TWRP from fastboot, then you'll have access to internal storage by TWRP
It's happening because it's trying to send you to recovery which is twrp 3. 0.4-1which is bugged so just go to fastboot and flash twrp 2.0.4-1 and then try booting in.. You can even update the phone by flashing the update zip by oneplus from recovery
