So I updated to the latest version supplied by Oxygen Updater, afterwards I reflashed TWRP. Sadly the TWRP I flashed is not working properly (need one that can decrypt). So I ran "fastboot boot twrp.img" to flash a newer version. When I do this my phone just shows a "1+ Fastboot Mode" screen and nothing happens.
This means I'm stuck; I can't use the already flashed TWRP to flash a new one (no disk access), and I can't boot a new TWRP. Also can't "fastboot flash recovery" cause of the a/b slots (can't find any info on how to get around this).
Any ideas on how to proceed?
Managed to fix it by using https://forum.xda-developers.com/on...nt/recovery-unofficial-twrp-recovery-t3931322
Just curious, but did you flash magisk before twrp?

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

THx mate! actually I downloaded the wrong file. With the correct one evreythink is working fine!!!
I was running stock OOS with Android 8.1 with the normal TWRP and Magisk working. When the OOS 9 got out, I installed the full OTA through TWRP (dirty flash) and everything went perfectly, with no problems whatsoever, but I lost TWRP and Magisk, of course.
Now in Android 9 I can't seem to reinstall TWRP (I'm trying with the latest bluespark): I can boot TWRP from fastboot and install Magisk, everything is fine, Magisk works great. However, when I try to install the TWRP zip (through the fastboot loaded TWRP), the phone freezes at the bootloader warning and doesn't boot (and I have to reinstall the full OTA zip to get the phone working again). Or, some other times, it reboots always to the recovery and never to the OS. Any ideas on how to solve this? Thanks in advance.
What version of bluespark are you using ?? v2

first fastboot boot twrp.img, the install twrp.zip , reboot recovery and then magisk..
I also tried to fastboot boot blu_spark twrp V2 IMG.... This ended in a black screen. I used the latest official twrp without a problem on pie.

Thanks! Did it in that exact order and now everything works. I was forgetting to reboot the recovery before installing Magisk.
don't flash magisk on the temporary TWRP

Cuz of kernel panic. When you boot into twrp after fastboot command - unplag your cable from pc when the command is done, then disable mtp, connect to pc and re-enable mtp.
Dont forget to click thanks
And yeah, use blu spark's TWRP, not official one
Came here from google.

This procedure didn't work for me, for some reason "fastboot boot twrp.img" was leading to black screen.
What worked for me was
1) Boot to fastboot
2) fastboot flash twrpXXX.img
3) Without rebooting, select recovery from fastboot's bootloader menu
4) If you are able to boot in twrp this time, then flash blu spark twrp.
5) Reboot
6) Try to reboot in recovery as usual
If all worked well, you should see twrp recovery.
Cheers.

C:\Android>fastboot flash twrp-3.3.1-x_blu_spark_v9.101_op6.img
unknown partition 'twrp-3.3.1-x_blu_spark_v9.101_op6.img'

I tried official twrp and is the same , I tried to disconnect from usb when mobile is restarting also nothing ...
so again ... I have restored phone with msn download -> unlock bootloader...
i have this issue sins i tried to install magisk and after reboot my OP6 doesn't boot to OS and give crash error
any other ideas ?
Solved I have to update system to more recently version. Why twrp doesn't work with oxygen is 5.1.5 ?
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...
I've tried and according to CMD, succesfully flashed the recovery, but I can't boot into it. From Fastboot and selecting recovery it takes me right back to Fastboot. I've used the MSM Tool, but my phone keeps powering on automatically when connected to my PC and puts itself right back into Fastboot.

I assume you are talking about TWRP custom recovery? You aren't supposed to flash TWRP in cmd (fastboot). Proper sequence is to fastboot boot TWRP.img, which temporarily does a remote boot of the TWRP img that resides on your computer. Once the phone is "booted" TWRP, flash the TWRP installer zip. Then flash Magisk, otherwise the phone might not boot (after flashing TWRP zip).
Also, make sure you are using an updated version TWRP. Current version is -75 from here (also has instructions on how to install properly): https://forum.xda-developers.com/on...nt/recovery-unofficial-twrp-recovery-t3931322
Reason for the difference in TWRP installation method, is due to the A/B partition scheme on the 7 Pro. With this scheme, there is no longer a discrete recovery partition, but rather recovery is a portion of the boot.img. As the boot.img partition also contains the kernel, you can't flash recovery directly from fastboot. The installer zip extracts your phone's specific boot partition, patches it to install TWRP, then re-installs the boot.img back to the phone.
Merry Christmas guys,
I have a really unusual situation.
First time that I have tried all tricks I know and I can't get myself out of this difficult situation.
I was trying to update Magisk with a patched boot file and after a reboot I was not being able anymore to access the system but only this black screen with the Crashdump Mode is appearing.
I can access the Fastboot screen, but no way to reboot to the TWRP recovery or to flash another boot.img, even through some pc flashing utilities.
Is there anything to try through another slot or something else?
I also tried:
fastboot flash boot_a boot.img
and I get this error:
FAILED (remote: Flashing is not allowed for Critical Partitions)
But my bootloader is unlocked and other commands like fastboot reboot works normally.
After I flashed through fastboot the images of boot, abl, dtbo, fw I can only access the TWRP recovery where everything is decrypted.
Any other ideas?
Try booting temporary into TWRP by using this command
fastboot boot twrp.img
If you can't use MSMDownloadTool
