[help] On Oreo, 8.1, latest, trying to install Magisk, and unable to install

I was following the guide at:
https://forum.xda-developers.com/pixel-xl/how-to/guide-pixel-xl-android-8-1oreo-unlock-t3715279
I started with a Pixel XL 7.2, unlocked, magisk, etc. I uninstalled magisk, updated all OTA updates, and then began the thread above.
I followed 6 - Extract boot.img from Fcatory Image and fastboot boot.img
The continued with 7 - Root with Magisk
booted to twrp, flashed twrp, no issues.
Rebooted to recovery, flashed elementalX kernel 3.04, and added magisk v16.3
No errors
Rebooted phone, and upon boot, got a message:
"there's an internal problem with your device"
From what I've read, that is not really an issue and has something to do with some things not matching, so, an update to magisk in the future will resolve it. So no big deal.
However, I don't see magisk manager, and have no root.
I reboot back to recovery, uninstall magisk manager, and reboot phone.
Still get the internal problem message, but no big deal.
I reboot back to recovery, and try flashing magisk again.
Still no manager, still no root (from root checker).
I try installing the magisk manager app directly, but, the APK cannot install, and just gives a generic error message of "app not installed".
Reboot to recovery, uninstall magisk again, wipe cache. Reboot, still same internal problem message.
Try to flash magisk 16.0 instead, repeat the above, and still no root, and can't install APK.
So, just kind of stuck at this point. Phone tells me that elementalx installed without an issue though, so, just seems like magisk is the last step. Any help is greatly appreciated. Thank you.

The message you get upon boot is from the kernel, nothing to do with magisk. not that it matters, it doesnt affect anything.
According to EX thread and EX's official websites "How to install" guide, you are supposed to install magisk first. Thats how i do it.
what you need to do is......
Reflash the stock factory boot img and let it boot.
Reboot to bootloader flash or boot twrp, and install magisk.
Reboot let it boot all the way.
Then reboot to bootloader flash/boot twrp and install EX.
Reboot.

Double post, sorry, butt.......

Read part one step three.
"3. Root your device (optional)
If you would like root access to your device, install SuperSU or Magisk. This should be done before installing ElementalX. Other root methods are NOT recommended. Root access will give you full control over your device and allow you to change kernel settings and tweak your device. To install SuperSU or Magisk, download to your device, reboot to recovery and install the zip you downloaded. Make sure you reboot into your system after the installation process completes. Ensure that root is correctly installed and working.
At this step, I usually make a backup of the stock rooted kernel. Now that you are rooted, you can do this very easily in EX Kernel Manager by selecting Tools->Kernel backup. This will save the boot.img."

Thank you for the help, will try it when I get a chance. The guide that I was following said for elementalx, flash kernel first. For exnoshadez, to do magisk first, for other kernels, do kernel first. I had read that some kernels need to go first, while others magisk needed to go first, and since that guide was specifically oreo, I thought kernel was first. But, thanks! Will try going back to factory boot image and progressing through.

So, I flashed back to stock boot.img, booted twrp, flashed twrp, and flashed magisk. But, Magisk still did not show up. I tried installing the magisk manager apk, but still get "App not installed" when trying that. At least the "there's an internal problem with your device" message went away.
Any other ideas on what to check when flashing, or why it's not "taking"?
Thanks again for the help.

Found out the problem:
Had to do:
adb uninstall com.topjohnwu.magisk
The key here was that I was upgrading from 7.2 to 8.1, and in the uninstall of magisk, I guess it left some remnant behind which prevented it from installing the new version.
The way I discovered this was trying to use adb to install the magisk manager apk, and that gave me the error:
adb: failed to install MagiskManager-v5.7.0.apk: Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package com.topjohnwu.magisk signatures do not match the previously installed version; ignoring!]
Then, I simply uninstalled it, then flashed using twrp again, and it worked fine.

Error at OTA update (60.5mb) - StockRom and recovery, MagicMask Android Oreo 8.1

Im having problems with an ota update. It weighs about 60.5mb and when im trying to install it, an error come up on the recovery screen. No more info aboiut it, only say "Error" and reboot. Im on stock android, but ive install magicmask and franco kernel v55. Would u tell how can i fix it? Tell me if you need a error log and how and i get it.
Sorry for my english.
Thanks in advance.

For an OTA to work at all, you must be fully "stock".
Your best bet is to download the latest "factory image" from https://developers.google.com/android/images#bullhead and apply that manually.
Important: remove the "-w" from the "fastboot -w update" line in flash-all.bat or flash-all.sh script, and you'll be fine.
Let it boot normally until the "updating system" message has completed. Then reboot into your bootloader, reinstate your custom recovery, and flash Franco kernel and Magisk. Your Magisk settings should still be there.

Problems rooting Xt-1952-1

Hey guys,
Hope someone can help me or point me in the right direction, I am having serious issues trying to root my 1952-1.
I followed the guide in this post to install TWRP
https://forum.xda-developers.com/g7-play/how-to/how-to-successfully-install-twrp-g7-play-t3979701
I followed all the guidelines but when i tried rebooting to recovery I ended up in having TWRP splash screen bootlooping, but was still able to fastboot boot twrp.
I then flashed Magisk, it completed and then i booted the phone back up, no magisk was in the app drawer. So i installed the Magisk Manager apk and this told me I was not rooted. Repeated the whole thing and still the same result.
I have also tried patching the boot.img file using magisk but same as before the phone is not rooted, on top of this I have also clean flashed the stock rom but again still not rooted.
Anyone got any ideas ?

Yeah the rooting process can be a little bit frustrating. You will have to copy the original boot.img file to your phone. In the magisk app make sure you enable recovery mode. Then you can patch the boot.img file. Copy it back to your computer and flash it via fastboot. But there is a catch. The phone will be rooted only if you boot the phone through recovery.

After trying to root with Magisk...

After I tried rooting with magisk, Pixel 2XL, 11.0.0 (RP1A.200720.009) And I flashed the patched .img file from magisk, My phone then right there got into a bootloop, I was able to get into the bootloader but nothing else, Now I cant get out of the bootloader and im wondering if there is someway to fix this, I saw a thread on this, Which says I have to change Magisk Manager to Canary but I cant because im stuck in a bootloop AND im in the bootloader, I already unrooted my drive by Flashing the original img but no help...
Any help?

If you flashed a patched img, then flashing back an unpatched boot.img would fix it. You can always download the the full factory image and flash it back.

if you reflash the factory boot.img then you'll get out of bootloop.

reflashing the factory boot.img seems useless. you can long-press the power button to force power down. then power up to the fastboot mode,and reflash the full factory image(11 or 10). the nomal methon working on 10 seems dizzy in 11 now.

fwiw, heres the path i used...i hate making it more steps than needed (tranferring boot image to device and back again for magisk patching for example)...
1) flash-all.bat (with wipe enabled - because clean install)
2) Immediately on reboot from 1 and before it gets anywhere near to beginning of setup: fastboot boot twrp-3.4.0-1-taimen.img
3) adb push Magisk-e66b0bf3(20425).zip /tmp
4) adb shell twrp install /tmp/Magisk-e66b0bf3(20425).zip
5) adb reboot
6) after reboot, install canary magisk manager (for whatever reason doesnt install from TWRP flash)
7) open canary magisk manager and enable magiskhide

This is caused by twrp
Use android toolbox, just boot twrp, flash magisk

boot into twrp go to advanced fix bootloop option reboot

Boot issues after removing magisk

Got the notice there was an OTA. As per instructions I tried uninstalling magisk and restore images. Got a toast notification saying no backups found.
Tried a complete removal of magisk, now stuck at the Bootloader unlocked screen.
Tried flashing the patched boot.img in fast boot and rebooting. Now I'm stuck on the boot animation.
Done with root on this phone, not worth the headaches. (TiBU was the only thing I use it for these days) Get me back to no magisk without loosing data.
[edit]
Ended up having to wipe litterly everything via recovery then it finally booted. :/

The patched image you're flashing won't work because you updated to 10.0.14. When updating, you're not supposed to uninstall Magisk, just disable the modules you have downloaded in the "Modules" section.
You need the updated root boot.img. I'll try to upload it later.

Thanks. At that point I hadn't installed the OTA update yet. I had just prepped by going into Magisk manager and (mistakenly) hit completely remove magisk. Which it did, then rebooted but left me hanging at the unlocked bootloader warning.
I tried flashing the patched boot.img from fastboot, and reflashing magisk from inside of the temporary twrp, but after a reboot I was left with the boot animation that never went away.
After I wiped it and got back in, I let it download the latest OTA and installed it.
So currently I'm at 10.0.14 now, but without root.
