HELP - TWRP on OnePlus 3 running the Open Beta 9 (Nougat ROM)

Here's the deal. I unlocked the bootloader of my OnePlus 3, flashed TWRP Recovery with "Tool All In One" through my pc. Then I was able to root my phone, I did it and then, flashed the Open Beta 9 through TWRP.
Now the problem I have now is that I'm unable to flash TWRP from my computer and I don't know why. It doesn't display any error or anything else. But when I boot into recovery mode, it is not TWRP, it's the stock one. Help me out. I want root and Xposed lol!

fastboot flash recovery TWRP.img
into recovery Vol Plus and Power
flash SU
beta9 is Nougat so xposed is not working yet.

You need adb and Fastboot.
http://forum.xda-developers.com/showthread.php?t=2588979&page=95
On The Fastboot PATH
Same directory, Put twrp.img
Shift and Right Mouse.Open cmd and type
fastboot flash recovery "twrp file name.img"
You can get TWRP.
I recommend TWRP .28
After you can flash any Rom and Kernel , SU etc...

You need modified TWRP Recovery to Run Open Beta 9, official TWRP won't work
Here's the link for Modified TWRP

Thank you guys so much, I successfully flashed TWRP on my phone. First time, it didn't want to boot but when I rebooted it id did
... Well, update: Booted into system and when y tried to boot into recovery, this time unplugged from the pc, booted with stock recovery -_-
... Update of the update haha: I downloaded the root zip and then I flashed the TWRP, Installed root zip and made a backup of the whole system and now, the TWRP recovery is installed permanently. Thank you if you guys followed my thread.

Twrp and flashing a Rom

So I've done a lot of reading and there are multiple threads with steps that aren't exactly clear or contradict each other or are outdated. I just want clarification on what I believe are the steps to flash a custom rom (7.1.2 since I can wait for 8) on a brand new Pixel XL.
Setup phone to the point of enabling adb debugging and oem unlock
Fastboot unlock
Fastboot boot twrp RC1 img
Flash twrp RC2 zip in twrp
Reboot to installed twrp
Wipe system, data, caches
Flash ROM
Flash twrp again
Reboot to twrp
Flash gapps and root method (magisk working for 7.1.2 or should I be using supersu? Also which versions?)
Flash twrp again??
Boot to ROM then setup and use like normal
Should this give me custom ROM, root and twrp that I can boot directly to without a pc again? As long as I do twrp flashing after a ROM each time it'll stick? Also, I keep seeing things for setting a pin before initial twrp boot but without spending 4 days reading I can't find the reason for it. Should I be flashing vendor, bootloader and radio for the latest Nougat release BEFORE unlocking or can I do it through fastboot prior to unlocking?
Coming from Nexus 6P and that was my first run in with the bootloader, radio and vendors so I want to avoid issues for myself. Phone should be here tomorrow and want to get down to business right away lol.
Any and all information is greatly appreciated. If all of this is answered in a centralized area please point me to it and tell me I'm stupid for missing it.

Assuming the bootloader is already unlocked and disregarding the unlocking instruction, these instructions are dead on accurate. I personally dont use magisk, but maybe another user will chime in. For 7.1.2 id use supersu 2.82.
You dont have to flash twrp again after flashing gapps and supersu, but its a good practice to have.

Thank you very much. I'm about to unlock and go nuts on my phone. New phones are so fun to fiddle with!

if you want to use magisk you'll need to flash a custom kernel before you flash magisk. Also you'll need a modified magisk zip. Search around the thread you'll find one, the latest version I found was magisk v13.3.
Edit: Just found out magisk is officially support for pixel on version 14.1 Check out the magisk beta thread.

Don't feel too bad my friend, the P2XL is a quirky little bugger to say the least. I had a heck of a time rooting 9.0 after I updated from 8.1, then outa the blue, it worked. Here's a few steps to try.
1. Fastboot twrp, then flash magisk, try to boot.
2. Fastboot twrp, flash twrp.zip, boot up, then go back to twrp and flash magisk. If no go, do the same steps, except after you flash magisk, flash the magisk uninstaller zip, then flash magisk again.
3. Fastboot into twrp, flash twrp.zip, custom kernel.zip, then magisk.zip. if no go, then try the magisk uninstaller.zip method again.
4. Stick with it, be patient, sooner or latter you'll find the right combo. Also, it seems easier to root using a custom kernel, if your willing to try it :good:

Maybe give the guide linked in my sig a shot.
If that doesn't help, try the following:
-once you've permanently installed TWRP, try rebooting to recovery after each additional step BEFORE rebooting to system:
install cust kernel, reboot to recovery, reboot to system
install magisk, reboot to recovery, reboot to system
if that doesn't work, try doing a mass install after TWRP is permanently installed:
in the same flash, install cust kernel and magisk, reboot to system
These have helped other users who have had odd issues with their set ups, but in the end, Pixel 2 XL is a fickle beast
Best of luck!

SOLVED
The only way (for me) to root my Pixel 2 XL is follow theese steps:
Rooting with Magisk
NOTE #4: This section assumes you are not going to install TWRP. If you are, skip to the next section and just flash the latest Magisk zip after installing TWRP.
Download the Magisk zip from the official thread and install the manager from the zip.
Grab a boot image to patch (either the one from the latest factory image or a custom kernel one) and push it to your device:
Code:
adb push <path_to_file> /sdcard/Download
Open Magisk Manager and click the Install button.
Click "Install" at the first prompt then choose "Patch Boot Image File". A file manager will pop up.
Select the boot image you want to patch and let Magisk Manager patch it.
Pull it off your device:
Code:
adb pull /sdcard/MagiskManager/patched_boot.img
Reboot into the bootloader:
Code:
adb reboot bootloader
Flash the boot image and reboot.
Code:
fastboot flash boot patched_boot.img
fastboot reboot
Open Magisk Manager and you should be rooted!

Rooting issues

I have a Pixel 3 XL and I was following this Guide to root it.
https://www.xda-developers.com/google-pixel-3-unlock-bootloader-root-magisk/
When I get to part 2-10 (The part to install Magisk) my phone wont boot into the OS. Instead I end up back at TWRP. If I reinstall TWRP from my download folder or restore a back up I can get back into the OS. I still have TWRP installed but no root. I know I'm doing something wrong but I'm not sure. Like I've said TWRP is install but not Magisk.

What Android version; Pie or Q, stock or custom? What Magisk version? Are you booting to TWRP (fastboot boot twrp.img) or did you flash twrp to the device?

I did this from a blank slate. Pie, stock, the newest version if Magisk 19.3. I flashed twrp to my device.

Try clean fastboot flashing the stock boot.img back onto the phone. You can get it from the fastboot factory img. Then just boot TWRP to flash the Magisk zip. The Magisk zip will need to be on the device for the booted TWRP to find it just like if you were running TWRP installed on the device.
An alternative is to use Magisk manager to patch the stock boot.img and then fastboot flash that patched img to the device.

I tried the easiest method first, which was installing the Magik app and flashing the zip, I got the following error,
Device platform: arm64-v8a
copying image to cache
Unpacking boot image
! Unsupported/Unkown image format
! Installation failed
I'll try flashing the stock image, but should I flash twrp again after the image? I've done this before in the past because some phones require it as part of the rooting instructions. Does this order sound right, flash stock image, reboot, flash twrp reboot, then Magisk?

Just tried the beta version (19.4) and I'm stuck in a standard bootloop. I'll try and get it into recovery.

No worries, I forgot to mention that I restored a back up

Surely not on Pie. I'm using 19.3 on the last Pie.

I'm on pie, but your first suggestion was the fix. I had to flash the factory img before doing everything else. I just had to put a little more time a side and not be lazy.

Pixel 3a XL soft #BRICK - please help

On my way to installing LineageOS I tried to downgrade Android version 11 -> 10. Unfortunately I used the WRONG INCOMPATIBLE firmware files from google's website (I think for 3 XL), that's why I have a brick now. ''Device is corrupt and no bootup possible.''
Access to Fastboot and STOCK Recovery Mode is possible.
Bootloader is Locked Now (it *was* unlocked before for flashing the firmware)
ADB is not working (since I'm getting stuck on ''google'' symbol when booting up I can't go to Developer Settings)
Factory Preset from Recovery Mode fails: ''can't send spi messages.'' Same Brick occurs.
With No Access to ADB (is it possible to set up from fastboot mode without enabling it in den Developer Options?) I can't try stuff.
And with the bootloader locked no way to flash a new Rom right?
I have NO IDEA what to do next, any IDEAS??
Thank you!!
#brick

Since you can get to recovery you should download the latest ota and sideload it from recovery.

https://developers.google.com/android/images
you should flash the stock image from recovery. Basically unzip it all and just run "flash-all.bat"

Thank you, this worked perfectly fine, since you don't need an unlocked bootloader to flash this system image.
However, I am facing a new problem on my way to installing TWRP Recovery Image...!!
CMD gives me THIS log:
Writing 'recovery' FAILED (remote: 'Not allowed to flash (recovery)')
fastboot: error: Command failed
- the device is unlocked (I even relocked it and unlocked it again, didn't work)
- I tried one other older .img for my phone from official twrp.me website, didn't work
Any Ideas?

You need the BL unlocked to flash unsigned/unofficial images, so make sure yours is unlocked. That being said, I'm not sure how solid twrp is for our device, I've never tried it. Twrp was/is a little iffy for android 10 never mind 11. Most around here just use fastboot to do what needs to be done. Most of it is pretty quick and painless, and twrp is not really necessary.

I'm pretty sure you would have to downgrade to android 9 (pie) and install a custom kernel to get twrp to install. Unless you want to rock android pie - like I currently am (Bootlegger's 9 - I like my smartbar customizations) - it's best to give up on TWRP and just use fastboot commands for android 10 and up.
If you do decide to downgrade to pie the elementalX kernel (ElementalX-P3a-1.06) works fine with twrp and is available on their site. Temp boot twrp via fastboot, flash kernel, flash twrp zip file, reboot to recovery and flash magisk zip for root (if you want root). But it may be hard to find older pie ROMs out in the wild to flash since devs have dropped support and will be focused on android 10/11.

Unlike most of the LineageOS Tutorials out there is used the Custom Recovery from Lineage to install LIneageOS! It was super easy, a few ADB commands and here it is. No Root, no TWRP whatsoever.
Follow wiki lineageos devices website instructions. Here you may also find the recovery data.
Thx guys/girls!

BUT I still cannot install TWRP Recovery on LineageOS 17. I am getting the same problem as quoted below.
I want to perform Nandroid Backups, any other way to that if TWRP doesn't want me? Maybe with a Magisk Root and some app from F Droid?

Twrp doesn't work very well on android 10 and above, there is a twrp install guide around here, but not much has come from it. When was the last time anyone actually made and used a nandroid backup? Not that backups aren't important, but that's a little antiquated. Besides, most are really trying to backup data, which is a shared partition on A/B devices. Generally, restoring data on A/B devices causes more problems than anything. Most data backups can be done with an app and/or making a backup of your internal storage. As for more sensitive things like your persist partition and whatnot, you can always use the 'dd' command to back those partitions up.
I should clarify, restoring nand backups of data causes more problems on A/B devices, apps that restore data and settings tend to handle it better.

Now having a different problem
I tried to install Magisk following this guide https://magisk.download/root-pixel-3a-3a-xl/
When I try to flash magisk_patched.img in fastboot, it flashes, but reboots to fastboot with "error boot prepare" displayed.
I am stuck in Fastboot now.
How can I get out of that?
I used the boot.img from the google firmware android 10 I built Lineage on. Should I use a boot.img from LineageOS .zip? Is there anything like this?
What is dm-verity?
Can I get to my previous unrooted device?
I have a Pixel 3aXL with LineageOS 17

A lot of devs wil upload the boot.img separately when they upload the rom, so wherever you downloaded Los from check there. If you just have a payload.bin file in your zip, you can always dump it and grab the boot.img there. You could always just reflash Los period to get boot back, then us 'dd' command to backup your own boot.img.

I got Lineage 17 w/ Magisk root running now and want to perform a full NANDroid Backup.
After some research it seems crucial to have a custom recovery like TWRP for that. There is the online nandroid thing - but I would need CWM or anything like this to restore?!
So my question is
a) is there another custom recovery (compatible with Pixel 3a XL w/ lineage 17 based on android 10) I can install and perform Nandroid backup with?
b) any other solution to perform this backup and restore? I heard there are cmd commands for that as well , but I'm a noobie not so sure to do that.
of course there are several apps out there to backup data.. but I don't trust ''any'' app to get root permission. In F Droid I couldn't find what I was looking for.
thank you for help!
