If your platform tools are up to date flash-all should work.
If you're on lineage 17.1 you should be able to boot twrp and flash/sideload the factory ota.

Use that if your phone is international model if not look around for the t-mobile msm tool. More details, more help. What exactly did you flash, how did you flash it, what recovery did you use....

How to flash a rom on oneplus 6.
Boot twrp: fastboot boot twrpxxxxx.img
Fash firmware OOS 10.3.9 or whatever latest is for your device. Get from repo on guides section here or from oxygen updater app. Make sure it's for your device. Don't flash global OOS on tmobile model...After flashing OOS latest, flash EvoX rom, flash twrp installer zip, flash finalize zip, reboot recovery, flash magisk latest. I use canary, format data-swipe to confirm in twrp, reboot system.
That's how you flash a rom on oneplus 6. Finalize is a script that can be found with simple search here on xda that copies firmware to both slots so you don't have to reboot recovery and flash OOS again. I used a Oneplus 6t a year prior to what I use now Pixel4XL and I flashed everything known to mankind available for it just this way.
Boot twrp,
Flash OOS,
Flash EvoX,
Flash twrp installer zip,
Flash finalize zip,
Reboot recovery,
Flash magisk
Format data-swipe to confirm yes,
Reboot system.
Update magisk once booted via magisk manager app icon in app drawer.
You should be able to hold down power+volume up and get in to bootloader node again and do this. Just keep holding them down till you see the "start" screen and let go, boot twrp from fastboot...

Please Help

Hello Guys
I was on a custom Android 12 rom. For some odd reason, my phone rebooted. Now i cant get into TWRP Recovery.
I can fastboot, but TWRP is for Android 11, and my Rom is Android 12.
What can i do to either flash stock Rom via CMD, or what can i do to get into TWRP?
Note i cant boot into my rom either
is there any way i can get into TWRP with an Android 12 Custom Rom?
TWRP is a GUI based recovery, a menu presented to you once you boot device into recovery mode, where you can select some actions from, it isn't part of Android OS itself, it doesn't depend on Android OS's version, AFAIK.
Sounds to me like you need to flash back to stock rom then use the xiaomi flash tool to set everything back to stock and restart the root process.
At this point I would advise against rooting android 12 as it is brand new and the root process is very unstable. Therefore I recommend only stock until twrp and magisk catch up.

okay so i managed to get into TWRP via fastboot. I have the stock OOS 11..
please tell me if i have the process right
Boot into TWRP
swipe to factory reset
wipe data/cache/davlik
Hit install and flash Stock OOS11
Flash latest TWRP
if that is correct cool
But after flashing latest Twrp, i cant boot back into twrp recovery. I again have to boot via fastboot.
I have flashed the TWRP boot image, but still nothing

Invalid partition name :Recovery

Hey guys, just got a NOS One Vision to install LineageOS but when I try to fastboot flash recovery "LineageOS zip"
I always get an error because the recovery partition does not seem to exist.
Then I tried TWRP on external storage. TWRP can boot then install itself: boot recovery from volume down boot up,
but then TWRP always gives an error 255 on flashing lineageOS that way.
Please help!
Just so you know, the phone came with android 9. After my tries, I factory recovered it and it is now at 11
but I did nothing since.
Any ideas?
Update: After letting the Motorola recovery tool upgrade the phone to 11, installing LineageOS went as per instructions

TWRP can't decrypt + Fastboot loop

Unsure if this is the place since its also related to TWRP 3.7, any help is appreicated
Got stuck in a weird situation and wondering if anyone has ideas.
Current State:
Slot_A on OOS 11, can boot TWRP via Fastboot
Slot_B on OOS 12, can only boot into Fastboot
Originally on OOS 11, booted TWRP and made backups of all partitions (data, boot, system image, vendor image, etc.). Forgot to move this to computer so this is all still stored on device.
Proceeded with OOS 12 upgrade (into Slot B). Patched magisk, rebooted, then flashed TWRP 3.7 (FBEv1), direct installed magisk, rebooted. - Everything was functional, but decided to go back to OOS 11.
Thinking I could just use the TWRP backup made on OOS 11, I did the following:
Booted into 3.7 TWRP
Restored the backup for boot, system image, and vendor image
Set active slot to Slot A and reboot
It doesn't allow me to boot into the OS (Presumably because the data was re-encrypted for OOS 12?)
Set active-slot=b and reboot, but it's locked to fastboot.
I've attempted a few things, but I can't boot back into OOS. I would prefer to retrieve my TWRP backups first before doing an MSM reset.
When on Slot_A (older), I can only boot into TWRP 3.6.2 and 3.7. I'm guessing 3.6.2 can't decrypt since it's only configured for A11 and under, but not sure why 3.7 can't decrypt my data.
- It doesn't even ask for pin when TWRP launches; maybe it's reading the System for Slot_A and thinks i'm still on A11?
- running `twrp decrypt {pin}` doesn't seem to work. Unsure if there's something done to my lockscreen pin to be used as the encryption key/password?
When on Slot_A, attempting to boot into either the system or TWRP hangs.
Things I've tried:
Flashing A11 boot.img and magisk-patched boot.img to Slot_A -> Hangs on 1+ Spinning dots
Flashing A12 boot.img and magisk-patched boot.img to Slot_B -> Hangs on 1+ logo (Does show up on ADB though)
Booting Slot_B into TWRP 3.6.2 (Official, and Nebrassy unofficial for A12) and TWRP 3.7 -> Gets stuck on "Fastboot Mode" screen (fastboot cli still responds) or Hangs on snapdragon logo
Edit: Ended up using MSM. Needed device for work
I have a similiar problem to flash twrp to my phone ,
each time i try i get a fastboot loop too and i have to reset/unbrick it with the msm tool back to android 11
i use the OnePlus_7_Pro_Global_OxygenOS_11.0.5.1 package to unbrick the phone , i dont know how long and often i tried now to get twrp to work so that i can flash a custom fw ... i want root and a android 13 based cfw but i dont get it to work :/
I got it working with crdroid. heres some stuff
guacamole - Google Drive
drive.google.com
be carefull
¯\_(ツ)_/¯​
------------------------------------
I got stable and decrypted fs RW working on crdroid 9.1 firmware other than some weird bugs
i put it in the 2023-twrp

I have the exact same problem! Have you found a fix yet? This seems to happen when I try to install Android 13 based roms, and when I install a rom like Lineage OS, using their recovery, it works just fine.
No, and I don't know why, maybe i do something wrong or it is the Modell that make this trouble.
I thinking to sell my OP7PRO and buy another one ( and then I have the same problem with the new phone )
No no let the jokes aside, it must work, i mailed with OnePlus Support Germany but they only helped me to install A11 w/root and recovery, i thought ok now I can update to A13 so I loaded A13, unpacked the boot.img, Patched the boot.img
Installed A13 w/out errors, rebooted - Fastboot loop
RIP
Started ranting instead
TWRP for guacamole development seems to be fairly scarce, last working recovery I tried was when they started using fastboot boot to enter it. It was pretty hacky even then, currently it seems that nebrassy is the maintainer for twrp for guacamole.
Github: https://github.com/nebrassy Android 12 thread: https://forum.xda-developers.com/t/recovery-12-official-teamwin-recovery-project.4269551/ Nebrassys Telegram has helpful info as well: https://t.me/NSSFB
last update I found was 2022:10:2 - https://www.pling.com/s/Phones/p/1835156
after a few days of torture I read a thread on here saying if you flashed twrp via magisk like you would if it was a magisk moule it would work normally. It worked on my device so I assume that its universal. I have filled my computer with guacamole related files Im uploading here before im forced to reinstall my os:
guacamole - Google Drive
drive.google.com
Just a fyi from what I have gathered from my experience you can get a stable twrp recovery with persistant / read write access and disabled encryption and basically use it with little error up until you try flashing a newer custom rom. My guess is when flashing a cfw the bootloader gets rewritten causing our boot image to become corrupted. Flashing twrp over / booting to twrp via fastboot or trying to install it via another custom recovery causes boot / recovery failures... meaning you cant really use it for flashing custom roms. I cant find the post with the install instructions I seen that helped me so here is what I think it was,
Found it: https://forum.xda-developers.com/t/how-to-make-twrp-work-in-your-stock-a12.4522667/#post-87985325
~ I have bricked this device constantly while ****ing around so unless youre prepared to go to war with the ****er, Id quit messing with it.
MSM flashing with windows is the only way to recover from the void.

~If you do brick I created a fastboot flashable A13 Oxygen os recovery rom and uploaded it to my google drive found under recovery_brick_fastboot.zip ~
Click to expand...
Click to collapse
lastly be mindful of a/b partition configuration or youll find yourself lost or bricked
Installation:
1. Obviously unlock the bootloader - OEM Unlock
2. Flash custom recovery (lineage/crdroid/etc)
3. (Personally I root here and again on the active slot so) flash magisk.zip
4. Reboot into installed ROM and install magisk android app and complete setup, reboot system
5. (another thing I like to do before flashing twrp) setup magisk enable all the basic options like prophide, deny list then set root userspace option to global.
6. Flash TWRP .zip (https://dl.twrp.me/guacamolev2/twrp-installer-3.7.0_12-0-guacamolev2.zip) via magisk
Alright! After all that you should be able to reboot into recovery via adb reboot recovery / fastboot or power menu and you find a working twrp recovery installed.
If you need help or want to **** around with the device you can @ me anytime and ill do my best to halp

You Confussing me a lot with your Posts before ...
i´m unsure what you mean exactly,
my bootloader is unlocked, with magisk i got a working root but after that i fail
what you mean with flash twrp with magisk ?
after unlocking the bootloader and get root, i tryd to flash twrp like before on other devices but that seems not working because i get then the fastboot loop
on another thread i found here on xda too, the guy wrote dont forget to activate the fastboot loop fix in the advanced options
but i not tried it yet again , so what should i do now ?
for now , i´m back on android11 , with stock oxygen os firmware
i have to do now the things like i did before again , unpack boot.img from the firmware that is installed on the device
patch it with magisk, flash it with "fastboot flash boot boot-patched.img" or is this step senseless ?
i mean you only wrote unlock bootloader and flash a cfw , but i don´t have a chance to flash a custom fw without a custom recovery ??
my recovery on my op7pro have no options for "install zip" or something else
addendum:
like i said you confused me a lot
addendum two:
or i do what i said before .. i sell my op7pro and buy me a one where i havent so much trouble installing twrp and root
i never had a phone before that made so much trouble in installing simple twrp ...
but i don´t found a phone yet that is compatible with kali and the pentest tools or wardriving tools like the oneplus , so i have a problem ,... i think i should drink now my selfmade blackberry liquor ( or blackberry booze ? ) and let the smartphone be a smartphone for now and power off my brain for a while
Yes, you need to patch your boot image via magisk and flash it with fastboot.
After you let magisk do its first time setup and then once it reboots you go to Magisk > Modules and flash the twrp recovery .zip file you got from twrp. link:https://twrp.me/oneplus/oneplus7pro.html just like you would if it was a magisk module.
the password for twrp decryption is your pin. Here are simpler instructions
https://forum.xda-developers.com/t/how-to-make-twrp-work-in-your-stock-a12.4522667/#post-87985325
****... I forgot a step.
after flashing twrp as a module in magisk you dont reboot, you go back to the main screen hit the install button and choose direct install
Now I understand it more, i had before rooted the phone successful with magisk, but then I made a wrong decision and booted into Fastboot and flashed TWRP in Fastboot Mode as I did it before with all my Smarties i had before, coz those way with Fastboot worked before all the time so I never thought that this is the error in the procedure
I give the twrp flashing with magisk a try.
Thx for the help

How to boot/flash TWRP for crDroid 9.2

I am going through this: https://forum.xda-developers.com/t/rom-13-op7pro-crdroid-v9-2-12-03-2023.4511589/
I have installed the stock OOS, but when instructed to use the crDroid 9.2 recovery, I am wanting to replace this with TWRP. Do I need to go through the ADB sideload process and setup crDroid 9.2 and then go back and boot the TWRP image from fastboot? At this point, I am not able to boot the TWRP image via fastboot boot twrp[version 3.7 something here).img. The image loads and the command completes, but the phone gets stock on the OnePlus fastboot splash logo.
My experience with Resurrection Remix is that I always had to flash TWRP from within TWRP immediately after flashing the ROM or I would be unable later boot the TWRP boot image from fastboot. I really don't yet know the technical details of the relationship between the system/ROM and being able to boot the TWRP boot image. Either way, TWRP is too useful to not have, so using crDroid without TWRP is a non-starter for me.
Once I get TWRP recovery on here, can I install crDroid.zip from TWRP, or does it always need to be ADB sideloaded?
Thank you!
have u managed to install TWRP?
im in the same with pixel experience. i want TWRP to be my recovery but the image used gets me the oneplus logo had o flash the pixel experience recovery again.
