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a lot of reading and there are multiple threads with steps that aren't exactly clear or contradict each other or are outdated.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.

Found this over in PN thread. Is it accurate? Seems similar to my process.

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.

Root w/o custom recovery?

Has anyone managed to root their device by patching their boot image and not installing a custom recovery (TWRP)?
I am referring to the method described on the Magisk website:

I think this would work with the xiaomi.eu rom. And I say it because when I install Magisk through TWRP, it works without the need to close AVB2.0 etc etc. Just install Magisk, reboot and you're good to go.
You need TWRP in order to flash the Xiaomi.eu rom though. Except if you flash all the partitions of the rom one by one through fastboot. And then flash the rooted boot.img.
Side note: I have not managed to root ANY rom (Chinese/global) on the Chinese device while keeping encryption. It always leads to bootloop, except if you disable forceencrypt, which of course leads to loss of encryption.

Do you suspect that the reason rooting via patching boot doesn't work is the encryption then? I'd be willing to disable encryption to obtain root with stock recovery

Not exactly. I suspect that it is the reason for bootloop when trying to install Magisk on the Chinese device. Because Magisk does not work on the Chinese device, even if you flash and close avb2.0, you get bootloop.
In global device + global rom, you can disable avb2.0 through TWRP after flashing Magisk, and then reboot normally to get a perfectly rooted phone while keeping encryption.
But if you flash the rooted boot.img through fastboot, how are you going to close avb2.0?

Of the handful of tutorials on the forums, which would you recommend for flashing TWRP and rooting the device?
Would it require me flashing the global rom in the place of my global (EEA) rom?

Attention because there will be no more updates for the redmi note 8 pro concerning the rom xiaomi.eu! (announcement on their site ...)

I flashed patched boot image without disabling avb and now I'm stuck in bootloop.
Is it necessary to disable avb before flashing patched image through fastboot?

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!

Cool. No more soft brick for you :good: Congrats on sorting things out. :highfive:

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
''bootslot: b
enter reason: error boot prepare''

Reflash the boot.img from Los17 to get back to proper boot up, then patch Los17 boot.img and flash that to have root.

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!

OnePlus 7T India, 11.0.9.1, booting only to recovery / fastboot after incorrect Magisk update

I have OnePlus7T Indian version. I was on 11.0.9.1 and rooted with Magisk Canary version. There was an Update to Magisk which I accidentally installed with OTA option instead of full. Now my phone is not booting. It goes into original recovery mode or fastboot only. How can I recover from this? I tried to flash the magisk patched image file and it shows as flashed but when I reboot I again reach original recovery / fastboot menu only. Please help!!

Problem solved but don't know how. I was trying many things and when I used Tool All in One to flash TWRP the phone rebooted into the system. Not even sure if TWRP is installed or not but everything is working now and phone is rooted. Not sure how it got resolved. Magisk is updated to latest version.

Hi. I am again having same problem. I updated Magisk Manager and Magisk and some other apps and phone was not booting. After many tries it again booted but all the modules in Magisk were off. So I switched them on and rebooted the phone and now it is just not booting. I tried to use Tool All In One to flash a TWRP but now there is no recovery. The phone is either not booting (stuck on Circle dot rotating) or just going into fastboot, does not go into recovery. I was on OOS11. I tried flashing original recovery through the tool but it fails. Any way out of this mess??

Thanks. I managed to boot the phone but having root problems. After spending a number of hours doing various trials and checking Xda threads I managed to get it to boot again but root was lost.
I again read more articles and learnt that I have to flash recovery to both partitions so I used Tool All in one, changed active slots and flashed the magisk patched image from this thread i think on both slots. But i am not sure. I managed to get root but the Magisk manager was not getting installed.
I tried few other things and finally i am now not able to root again. Phone is booting after I flash a recovery but I am not sure if it will boot if restarted or go into loop.
Can anyone explain the proper procedure and sequence to follow for rooting and which files to use.

Hi. I already used these boot images but I was still having a problem. I had flashed the stock image to both partitions and then the Magisk patched image also but either I was not rooted or Magisk App not working. Finally got things to work by installing TWRP to partition a I believe. I changed active partition to a and then flashed the twrp recovery. Again changed active to b and booted and had root. I had to install Magisk Canary 25210 version only as other versions did not install. After checking on net it seems this version is faulty. So I installed Magisk Delta, then installed Magisk using Direct Install option, rebooted, checked regular Magisk Manager and showed the same Magisk version. Removed all modules from old Magisk Manager and unstalled the app. Setup Magisk Delta modules, hide, SuList as well as apps like LSPosed, HMA etc and now everything is working again.
I still am not very sure where the recovery is installed, on partition a or b? And if a difference recovery is installed on each partition what happens? I am pretty sure I had not installed TWRP on partition b. I am also assuming that once I set a partition as active and flash a recovery in fastboot that recovery is flashed to that partition, is this correct? Things are working but I don't know if the phone will go to recovery mode from system, I have not tried that. So I am not very clear yet but still got things to work.

Question Fingerprint Enrollment not Working After LineageOS Update

I have 2 Poco F3s with the latest LineageOS nightly build installed (20230429). On one of them the fingerprint unlock stopped working after the update and when I go to the fingerprint settings it seems the fingerprints that were enrolled are gone and I am presented with the "Set up your fingerprint" page. When I click through, instead of enrolling fingerprints I get a popup that says "Enrollment was not completed. Fingerprint enrollment didn't work. Try again or use a different finger."
I have tried searching for other people reporting this problem, rebooting several times, and rebooting into safe mode. I am hoping that someone here can advise me what to try next. I am hoping to avoid wiping the phone. Is it safe to reflash the same build from LineageOS Recovery?

LineageOS for our phone is still based on Android 12.1, right?
In that case, try flashing the last Poco F3 v13 Firmware for your specific region (EEA/Global/whatever). xiaomifirmwareupdater.com is a good source.
Not sure if LineageOS Recovery is capable of flashing Firmware, but OrangeFox Recovery (which I use) definitely works. TWRP too.
Also try removing Screenlock entirely.

Thanks for the reply. The baseband versions seem to be different on the 2 devices. I've downloaded the firmware for the device from the link you provided. I had installed LineageOS recovery because I had read about people having issues with TWRP on this device, and I didn't want to risk the hassle. Can I flash the firmware using adb or the Xiaomi flash tool and retain user data?
I don't believe the screen lock can be disabled because some Microsoft apps on the device require it.

If you imported your phones, use the Original Region, and last v13 version of that.
The Firmware ZIP-file is a recovery-flashable ZIP, so only using Recovery, or ADB Sideloading inside Recovery ("adb sideload <firmware.zip>")
You will not lose user-data. The firmware-install only updates the firmware-related partitions on your phone. Unrelated to your ROM-related partitions and your data-partition.
You don't have to install OrangeFox Recovery or TWRP, you can simply boot it:
"fastboot boot twrp.img"
This is the Fastboot command to boot a Recovery-IMG file from your PC.
I use this Recovery: https://orangefox.download/device/alioth
You have to extract the "recovery.img" from OrangeFox.zip.
Or you can install OrangeFox Recovery by installing the ZIP itself.

Thanks for the detailed reply! I used TWRP on all of my past devices but I will try OrangeFox. I had not heard of it. I will update after flashing the firmware.
Update: I flashed the firmware for my device from here via adb sideload in LOS recovery and the fingerprint enrollment is working again. Thanks! OrangeFox recovery is going on both devices next.
