can boot recovery from fastboot but can't flash!

Hey guys,
My friend is having some issues with getting twrp on his new oneplus one:
the bootloader was succesfully unlocked and we tried flashing the twrp recovery on it (both the latest version and the previous version) fastboot said that it was succesfull but when we tried to boot the recovery by holding power + volume down the device hung on a black screen and needed to be restarted, and this happens everytime! However if we do fastboot boot openrecovery....img it takes a while but the recovery boots just fine!
what's going on here? can anyone tell me why it won't boot a flashed recovery?

I have the same issue as you, and yet to find an solution. Try using Philz Touch or CWM instead, both worked for me.

Many people don't know the correct procedure to boot into recovery using the button combination, what you need to do is first hold volume down, then hold power as well, the phone will vibrate and you'll see the OnePlus splash screen, after about a second you can let go of the power button and keep holding volume down until it boots into recovery. If you continue to good the power button after seeing the splash screen the device becomes confused and thinks you're trying a hard reset.

[Q] Can't boot into recovery?

So, I got my new OnePlus One today and I tried to get CM12 onto it. I was following the [GUIDE] How to Install CM12 on the OnePlus One- Android Lollipop/5.0 on the OPO forums, and everything went well until I tried to get the TWRP on there. I flashed the recovery and rebooted the phone. I turned it off and then tried to boot it into recovery but it doesn't, it just hangs at the OPO logo until I hard-restart it.
I've tried factory resetting it and doing
fastboot oem unlock
but nothing happened. The factory reset pretty much just reset the phone. I think I might've messed up the kernel. How do I fix it?
EDIT 1: I've tried reflashing twrp recoveries and nothing. When I hold power+volume down, it powers on, shows the one plus logo, then reboots and just goes to the lockscreen.
UPDATE 1: I managed to manually flash all the CM12 files and use lollipop. I haven't tried the recovery yet but I'll keep you guys updated (if any of you even care).
UPDATE 2: Apparently flashing CM12 made the recovery work. Everything works as it should and the OTA to the most recent CM12 worked perfectly.

You're probably doing the button combo wrong. Hold volume down, then hold power (so you're holding them together), when you see the boot logo let go of power but keep holding volume down until you reach recovery.

I was curios and enabled advanced reboot to try and boot into recovery and it worked (after I had flashed CM12). Everything's working now.

How did you manually flash CM12? I think I'm having the same trouble you were having. I used the oneplus toolbox from the forum to unlock the bootloader, then flash the TWRP, but no luck in getting into recovery mode. It just boot loops with the oneplus logo until I release the volume down button at which point it then boots to the lock screen.

@Heisenberg I'm also having trouble getting into recovery. I've tried the different button combos (power + vol down; power + vol down and release power) as well as the advance reboot options to get into recovery, but they all fail. I get the 1+ logo and after I let go of the volume down button the screen goes black and boots again to the 1+ screen and then to the lockscreen. It's almost like it doesn't recognize the recovery. I tried putting the stock recovery back on using the image in the OnePlus One toolkit folder, but that one doesn't work either. In addition to unchecking the "CM Recovery Update", are there any other settings that could be causing problems?
For background info, I initially used the toolkit interface to unlock the bootloader and then flash the recovery. The bootloader unlocked with no issue...it wiped my device and I was in sync with the "How to root" video posted by alex.inthi. I got sidetracked after the (seemingly) successful flash of TWRP onto the phone I kept getting booted into the Cyanogen recovery. I realized out that I needed to uncheck the setting to keep it from overwriting TWRP and after that was not able to boot into recovery. After finding your beginners guide (thanks, by the way, very well written) I tried using fastboot from the command line as you show, but still no luck.
Thanks in advance for any help...

Okay, I must have been having a special kind of moment - I've got TWRP 2.8.7.0 running on my handset now. I may have been holding the volume down button too long, or it may be that I was using an older version of TWRP, but I'm going to go with the former. I've also been able to successfully flash and boot into Philz 6.59.2

Having the same problem
I am having the exact same problem and cannot seem to find a solution. Recovery screen just doesn't appear, but goes to lockscreen.
Tried erasing, flashing both twrp, philz etc., but nothing works. The phone doesn't recognize the recovery status. Advanced booting does the same.
Update CM-recovery is checked off, phone is unlocked. I've followed every step of the big guide down to every detail.
Is manually flashing the 12.1 ROM the only way and in that case: is it hard for a relative newcomer?

[Q] HP Pro Slate 12 - recovery mode and factory reset both disappeared!

Hi everyone,
I'm sorry if I post this question in a wrong section but there is no thread for my device on xda.
It seems like I ruined the recovery mode of my Android tablet. It's a HP Pro Slate 12 tablet with Android 5.1.1 on it. It's rooted. I wanted to install CWM Recovery to backup everything, but my device wasn't listed as a supported device. My friend told me I can install the LG G3 recovery instead because it's compatible. I installed that. Since then recovery mode completely disappeared. The device still boots in normal mode and works, but I cannot boot into recovery mode anymore. I really need it because the device boots normally but sometimes acting strange since I rooted it. I'd like to try unrooting it by going into recovery mode or doing a factory reset, but both options disappeared.
Here's what I've tried:
- I Googled this problem very thoroughly, but didn't find any help aside from "hold down 2 buttons to go into recovery mode" type of answers.
- I tried holding down volume up+power buttons while turning it on, but didn't work.
- Tried holding down volume down+power. Nope.
- Tried rebooting inside Android into recovery mode with Quick boot app. It rebooted my device but again it went into normal mode instead.
- Tried to reboot into recovery mode with ADP and FastBoot in Windows. ADB recognized my device (listed the serial number), Fastboot didn't recognize my device. So I tried to reboot into recovery with ADB. Same stuff happened. The device rebooted into normal mode.
- Tried to do a factory reset. DIDN'T work! Rebooted into normal mode once more. The factory reset hasn't deleted anything.
- I have the latest available update.zip from the official website for my device, but without recovery mode I cannot install it.
Any ideas? Did I really lose the possibility of recovery forever with a single click?

Hello did you find a solution to your problem ?

Phone stuck at Boot screen after installing TWRP recovery 3.2.1-berlin

I have BLN-L22 device. I installed TWRP recovery 3.1.1- berlin and it installed correctly. Then I found the latest version 3.2.1-berlin on official TWRP app. So I flashed that one and rebooted to recovery. Since then the phone is stuck at the bootscreen which shows 'Phone is unlocked, booting' message.
I can't connect to PC and how can I recover to original?

Official TWRP app (and relative site obviously) leads to a non working build of TWRP, i stumbled upon the same scene too while flashing official 3.1.0 version took by their site... Don't know why. Modded versions of TWRP made by OpenKirin team and HassanMirza01 works correctly instead. Here https://forum.xda-developers.com/honor-6x/development/twrp-honor-6x-hassanmirza01-t3733201 you'll find a working 3.2.1-0 version, i tested it by myself.
Now, to get rid of this and flash a working TWRP, you have to boot to fastboot mode with manual method, so begin with completely shut off the phone by keeping held power button for 10+ seconds.
Then, connect the phone to PC with the USB cable, and boot it up by keeping pressed power button and held down volume - immediately as you hear the vibration. From fastboot, you'll be able to flash back the working TWRP.

Problem Solved

Hi Thank you so much. The phone was restarting continuously after holding the power button. So I tried by pressing the power and volume down button which took me to fastboot.
Then I could install the compatible version of TWRP successfully.:good:

You can successfully flash even non compatible images. the problem only arises when you boot them. Simply, they won't be able to boot because they're incompatible.
first, get into fastboot, flash compatible recovery(they are different for emui 5 and 8, so check before you flash). Then boot to recovery by pressing and holding power and volume up button at once from the fastboot mode itself.
Update me with the result. I'll tell you what to do next based on whether the flash works or not.

Stuck at TWRP Loop!

My phone got stuck at TWRP Loop!!
So, there is what i did...
I flashed Samsung a7 firmware ANDROID 10 [download from firja] and it worked. I needed to root my phone and tried Magisk new app.
But, with new Firmware I did not had TWRP installed, so I flashed TWRP with oden as instructed in this POST [BTW, I followed first method , not the *****OREO ROOT INSTRUCTIONS:***** ].
** TWRP version is 3.2.3-1_ashyx **
After that my phone got stuck at TWRP Loop.
Phone will not boot to normal , only BOOTLOOP to TWRP. Most of the time TWRP doesn't load fully and TWRP screen seams Black Line [in horizontal axix, MY phone display fine, it seems come from The TWRP!! ].
So, I am kinda STUCK at this TWRP Loop and TWRP load at it LOGO nothing more.
I tried every possible KEY combination to get to the fastboot mode/download mode but failed.
One or TWO time I was able[or it did it self!] to boot into TWRP (TWRP loaded but , with BLACK line) , i tried to enter download mode but failed.
So, what can i do?
-Thanks

I got the same problem, i did this: Power + volume down next when it restarted fast pressed v+ and v- and plug in the cable before it showed samsung logo

Nothing to worry and don't panic,
I've been facing problem like this.
To enter bootloader / download mode. With USB Cable plugged You must press and hold Power + Vol Down button then count it for 7-8 seconds, after that immediately release Power button, and press Vol Up + Down. Repeat this step if fail. U will see Download mode.
Regards.

You hold volume down + power button for 7 seconds and phone will be power off.
Then you press both volume buttons (vol up + vol down) and plug in cable what is connected to computer, this pusch you to download mode of phone.

Hi, Bennie from Holland here, with the same problem: tried to flash Twrp to the Samsung A750FN and now stuck in not working Twrp logo, flashing for 2 seconds and further a black screen< The fastboot using Odin can be used via the method described by szimin22, bur the adb fastboot gives no response. Does someone know the correct trwp version for this mobile or a firmware file that can be flashed by Odin?

A Week Later ...
i have installed on the a7 the firmware dated okt 2020 and i can install without any prob trwrp or PBRP! but the machine goes into bootloop again. The only thing which seems to be resolved is a normal functional recovery. Now the return to the phone itself and we are home! any suggestions, pls give us a chance to not smash the a7 through the kitchenwindow
