cannot fastboot boot twrp on 5.1.9 - OnePlus 6 Questions & Answers

hi..can you all help me..im already unlock my bootloader and follow the guide..but im stuck in fastboot boot twrp..it show cannot load...help me

Try the command "fastboot devices".
Does your phone show up in the list of connected devices?
If so, when you use fastboot boot xxxxxx are you attempting to boot using the zip file or img?
When using fastboot boot you must boot with the img, but then when you've booted it and want to flash it through TWRP, you flash the zip.
Hope this helps!

Flash recovery, stuck on dead android with exclamation mark

Im trying to flash either CWM or TWRP viea fastboot, i download the recovery, re name it to recovery ( recovery.img) place it in my C drive folder and then type fastboot flash recovery C:\recovery.img
however each time when entering recovery from the boot screen it ends with a dead android and an exclamation mark, what next?
Are you booting android before booting recovery
It's easier to put the image in the same location as fastboot so you just type
fastboot flash recovery recovery.img
After classifying I've rebooted into android, then powered off and back to recovery, followed by recovery then the dead android.
That should read after flashing, not classifying.

Try opening a cmd window in the folder with your image and flashing, ( shift+right click) and boot straight into recovery, without restarting...

Are you actually reading what we're posting? The post above yours tells you what to do so follow that and it should work
Its because of the install recovery shell script replacing recovery on first boot of android. You'll want to remove those scripts
Basically dont do "fastboot reboot". Just boot from bootloader directly into recovery, then using TWRP file manager, delete the scripts.
/system/recovery.init.boot.p
/system/bin/install-recovery.sh

Exactly. Gosh, how hard can this be.
People don't read - if they did, they would know.
Android has been using this for a while now, to ensure stock recovery stays there.

TWRP install dont work

Hi guys.
I unlocked my bootloader, and installed the Global Beta Rom via TWRP.
Now, that I am finishing that, TWRP is not installed anymore. And I can't install it.
When I boot into fastboot, and install TWRP like usual, everything is ok. No error appears. But when I want to boot into TWRP via key-combination, nothing happens. When I boot MiUi again, then reboot and try to boot into TWRP again, the Mi-Recoverymenue appears. But not TWRP. Can anyone help here?
After ROM package installed, boot and setup everythings you need, reboot to fastboot mode.
You must install TWRP again, then boot to TWRP by using command, same as the first time you install TWRP. Full commands:
1. fastboot devices.
2. fastboot flash recovery twrp.img
3. fastboot boot twrp.img

Done that.
Device reboot, screen turns black. Then device reboot again, and MIUI will start.
After you install TWRP via fastboot command boot into TWRP via fastboot using the TWRP image on your computer. After TWRP comes up disconnect your phone from your computer, go into the TWRP reboot menu and select reboot into recovery. After you boot back into TWRP it should stick until you flash another ROM zip.
Same issue here.....please have a look at attached picture to see what I have done.
Even after a couple of minutes the screen remains black after trying to boot into TWRP.img with "fastboot boot twrp.img"
Is this a wrong command?
OK with rebooting the system is replacing TWRP, mens I need to go directly into TWRP without rebooting OS., but neither the command above nor ´"fastboot reboot" and simultaniously holding Vol+ and Power ware entering TWRP .....even more
Entering "fastboot reboot" afterwards, device is rebooting normally.
Would be great to explain how I can successfully get TWRP run.
Thx a lot!!
MIUI overwrites the recovery with each boot.
You'll have to get root access and adjust s few files (there is a guide somewhere here on xda) to get it to stay

Stuck on "Bootloader is unlocked" screen, can't boot into recovery

So I wanted to root my op6 after updating to android 10
(OnePlus6Oxygen_22_OTA_041_all_1911142043_dde113e53cd0f9.zip)
I tried booting into twrp via fastboot using fastboot flash boot twrp.img (twrp-3.3.1-x_blu_spark_v9.101_op6.img, my bootloader is unlocked).
I then tried rebooting directly into twrp, but now it's just stuck on the "Bootloader is unlocked" screen.
I can still boot into fastboot, but I can't boot into recovery or reboot normally since it just gets stuck on the bootloader unlocked screen.
Please Help!
Edit1: Changing my boot slot from b to a gives me access to the stock recovery. not sure where to go from here though.
Edit2:Fortunately, ManikandanGuru had uploaded the stock boot.img, which works perfectly.
happened to me too. you just did a mistake and flashed the twrp recovery not to the recovery directory, you flashed it to the boot. if you want to make your recovery "twrp recovery", you just needed to do "fastboot flash recovery twrp.img. and if you want to make the "twrp recovery" only once (recommended), just do "fastboot boot twrp.img". now the only thing you can do is to flash the stock boot.img, like you did, or just to send your phone to phones fixing lab (like i did). it's much better and safe. they just flash on your phone the original oneplus 6 boot.img, not the stock one.
btw, i recommend you to use other twrp.img that built specially for android 10 (its safe, i use it). you can download it from https://drive.google.com/file/d/1Ndts4-CLP3o0kvs8wL40w3HLoyqMfwfy/view?usp=sharing (dont worry i uploaded it by myself).
good luck
Happen to me yesterday....boot on bootloader and use some tools from Mauro frio to reinstall everything with a batch-file...

Unable to boot twrp.img on fastboot after update

Hi,
I update my OnePlus 6 yesterday and as always I but magisk and twrp.zip on my phone storage, then I put it on fastboot mod, I check with "fastboot devices" if my phone is detected, then I use "fastboot boot recovery.img" and my phone stuck at fastboot screen, the custom recovery image doesn't boot and I can't install twrp and magisk and root my oneplus.
Never happened before, do you have any idea of the problem ?
Sorry for my english and thanks for your answers.
Try command "fastboot flash recovery.img"

Any way to install TWRP on mix 3?

I have Mix 3, unlocked bootloader. I made a flash of the latest TWRP 3.5 perseus for Mix 3 with the command:
fastboot flash revovery twrp.img
Later I used the command:
fastboot boot twrp.img
the phone is rebooting and there is only a black screen. When I restart it manually and enter recovery, there is only a stock version (MiRecovery)
I have exactly the same problem. It only works when I execute the command
fastboot flash revovery twrp.img
twice.
However it I try to install any custom ROM via TWRP it ends up in a bootloop...

Thanks for the hint, i was desperate, it wouldn't boot into twrp at all, even with "fastboot boot twrp.img". Now let's flash some custom rom hoping it won't bootloop...
