couple pixel 2 questions regarding Android 9 - Google Pixel 2 Questions & Answers

So i just flashed Pie on my P2 and decided i would do the persistent install of TWRP so i could backup and restore easier. However, when i did, a system reboot would just take me back into TWRP. I had to reflash the factory image to fix it. I was using the latest TWRP.
Anyone have this issue or know how to get around it?
I tried the install via fastboot method (adb commands). should i just try fastbooting into TWRP then manually installing the zip file from within TWRP? Also saw one post that said to just reflash magisk after flashing TWRP and that will fix it.
Also, i noticed when you long press the back button, after a second there's some haptic feedback like its firing....something. Can this be used? would be nice to get back the long press to kill app option like custom roms have.

I am having the similar issue. I installed magisk via twrp and then I can no longer boot into the OS. It also seems to be screwing up twrp,so I also have to reflash twrp

1. you are posting in the wrong sub-forum. there is a q&a sub forum
2. report your thread, so it can be moved
3. what steps did you do to instal twrp?

reported it
so i just had the zip in my adb folder and pushed it to temp with:
adb push [twrp filename].zip /tmp
and installed it with:
adb shell twrp install /tmp/[twrp filename].zip
when i try to reboot to system it just boots right back into TWRP. I may just try what i saw someone suggest and install magisk after twrp instead of before.

cool thanks. The way i was doing it i actually found off a thread here. dont remember who posted it now though.
edit: another dumb question since i didnt see it there. to get into TWRP i just reboot into the bootloader and then go to recovery right? think thats how i remember doing it years ago when i used to mess with custom roms.

you will have to flash stock boot.img for your security patch as you might have overwritten that with previous try. Once you have stock boot.img flashed, boot into Android to see everything is working.
Once that is done,
fastboot boot twrp.img
then flash twrp zip
reboot into system.
to boot into twrp next time. boot into bootloader mode, use volume rockers and when you see recovery use power button to select.
also, you will have to flash twrp zip after every kernel and/or rom flash if you want to keep twrp.

I installed twrp on my pixel on 7.1.1 it reboots to tarp again I got it to boot to the p.s. by clicking reboot / a on bottom left option but get error codes and can't open a lot of apps. I tried to install a tom and clear device cache and cause fails. Anyone know how I can fix this. I thought I used all the latest files

Did you fastboot boot into TWRP, then flash twrp-pixel-installer-sailfish-3.0.2-0-RC1.zip? Were you stock prior?
Installed img through pc then installed the zip file with twrp. I found a article here stating I need to flash stock ing to get back to normal

Yes, you are not supposed to install twrp, just boot into it. If you install it by mistake, you go back, flash stock boot.img, and do it again.
This is from Dees_Troy's post located here
https://forum.xda-developers.com/pixel/development/twrp-alpha1-pixel-devices-t3500314
Installation:
If you already have TWRP installed: Download the latest zip and install the zip using TWRP.
If you do not already have TWRP installed: Download both the img and the zip. Copy the zip to your device. You will need to have fastboot binaries and the correct drivers installed. Power off your device completely. Hold volume down and turn on the device. Your device should now be in the bootloader. Connect the device to your PC. Open a command window and run the following command from the proper location:
fastboot boot path/to/twrp.img
This will temporarily boot TWRP on your device. If you are using a lockscreen pin/pattern/password and do not get prompted to enter your passord, reboot to the bootloader and try again. Go to install and browse to the zip and install the zip. If you are currently rooted with SuperSU, you will need to reflash the stock boot image before installing TWRP. After installing the stock boot image, follow the instructions for installing TWRP. Once TWRP is installed, grab the very latest SuperSU released on 2015-11-15 or later and install SuperSU.
If you accidently flash TWRP to your device using fastboot instead of temporarily booting the image, you will need to download the latest factory image for your device and reflash the boot image.
@Tulsadiver First off, thanks for the post on this. I installed TWRP to slot A by accident and am finding myself in this same predicament (though I found that I can boot by switching to slot B). I found another post online that mentioned what you commented on, specifically:

Having previously downloaded Oreo 8.1 and setup root, I had loaded into TWRP, went to install, selected the TWRP zip, and installed (as per what you had suggested and what I read earlier). This is what led me to the current problem, making me realize that I'm missing something in the description. Now, I likely don't need to flash TWRP (I don't develop and used flashfire to do upgrades) but my last upgrade left me rootless and I felt having it installed would make life a little easier.

Things have changed with 8.1. you have to root with magisk. From slot b you cannot fastboot flash boot_a boot.img?
I believe the instructions now are to boot to TWRP, install TWRP pixel installer zip, then flash Magisk zip
Here is where TWRP files are here

I hadn't tried yet. I was worried about messing things up further without asking for help online first. I'll give this a shot later. Does boot.img refer to the android image file? (ie: what I'd download from the OTA site?)

Yes, the zip file that is located where the flash-all.bat is. Unzip it and flash the boot.img.
I bought a Pixel 2 on swappa. It had different bootloader's on slot a and slot b. I couldn't flash updates when on slot a. I thought I was hosed but from slot b I could flash to slot a so now I'm fine. Slot a had a preview bootloader.

Can you explain what exactly were you doing ?!
Just hold the power button for 60 seconds or so, it should reboot normally. Did you flash twrp or just do fastboot boot twrp?
I'm new to this while A/B partition. I went through all the steps and my phone is rooted, with Magisk and TWRP. All seems to be fine. My question is this. When I boot to the recovery (TWRP) and choose the reboot option it defaults to Current Slot: Partition B. If I reboot to partition B it goes back to TWRP. I have to select Partition A to get the device to boot to the system.
Is this normal? Do I need to set it up in a different way?

To keep TWRP as the phones recovery, you'd first need to do as you did "Fastboot boot twrp" but that command will only allow you to boot into TWRP through your pc or whatever you ran that command on. After you've entered that temporary recovery, you'll need the TWRP installer .zip file, and flash that inside of that temporary TWRP. Then you can reboot into recovery on your phone again since it has been installed to one of the partitions.

You have to flash magisk after flashing twrp or else you are going to get this bootloop you are talking about
phone open again
my phone is back up and running again. i changed the partitian slot from A( the broken one with no OS) to B(the unchanged one) and it is now working again. if anyone is having the same problem the try to change to the second slot. it happend in twrp enchilada 3.2.2-0 if it is important. thank you all for your support.
I may be mistaken but I believe all you need to do is flash magisk to get up and running again

Why? You should be able to just flash the TWRP installer into TWRP and so its flashed into both boot_a and boot_b. It should boot ok to system from there, Magisk is just another mod to the boot partitions, like a custom kernel, etc. It should not be necessary at all, why you guys keep sayin Magisk is necessary for anything? it isn't.

Because you do. The OP6 will not boot with custom recovery unless it's rooted. I believe this is because the recovery and boot partitions are merged on this device. You're welcome to bootloop all day if you don't believe us.

Asking "why?" is not to not believe you, and the personal bootloop all day attack is out of the matter. TWRP is flashed on the ramdisk and should boot stock, unless something derped, if it doesn't boot I honeslty don't understand why, what is the exact reason?

I don't know for sure either, beyond what I said above. But everyone who has reported not flashing magisk has bootlooped.
If I sounded snippy, it was only because your post above was appearing to deny the reality of what is a very well-known issue with this phone.

I am not denying anything! just surprised because on TWRP website they clearly state that no post-twrp-flashing step is needed:
https://twrp.me/oneplus/oneplus6.html
The OnePlus 6 uses the newer AB partition scheme first introduced on the Pixel 1. As such there is no recovery partition. Instead, the recovery is part of the boot image. You will temporarily boot TWRP to perform and later perform a more permanent TWRP installation. First download the TWRP zip file directly on your device. If you don't download the zip file to your device first for any reason, you will need to adb push the zip to the device because MTP is not currently working on the OnePlus 6 in TWRP. If you are unable to use adb, you can also use a USB stick with an OTG cable, if you have those handy. Power off the device. Hold volume up to get into fastboot mode. Run this command on your computer: fastboot boot twrp-3.2.1-0-enchilada.img
In TWRP, tap on Install and browse to the zip and install it (the zip will probably be in /sdcard/Downloads). TWRP will now be installed to both slots. TWRP is now installed and you can reboot and use your device as normal.
MTP is disabled because it causes a kernel panic sometimes with the stock kernel.

Maybe the issue here is that the unofficial TWRP that everyone used NEEDS magisk while the official doesn't?

I think most people have moved to the official version. If it doesn't need magisk to avoid a bootloop, that's news to me. Not saying it's not the case, but I haven't seen any mention of it.

phone has lost root issue

I used magisk on my phone for roots right but it has lost roots. I tried to go into recovery to reinstall magisk but recovery isnt booting, when it select advanced it gives me fastboot or recovery options but when I select recovery its goes back to the start again. I have tried to reinstall TWRP using this method
https://www.xda-developers.com/official-twrp-oneplus-6-huawei-p20-pro/
but I then get a crash dump window.
Please can I get some advice how to proceed?
Thanks
Make sure you're using 3.2.3, anything prior to that is not for Android Pie. If you updated your OS that is more than likely the reason you lost root. Make sure that you download TWRP.img and fastboot through the image before you try to install TWRP permanently

Good deal glad you got everything working.
I'm on stock android 10 and I have accepted an update I was offered yesterday. It seems everytime I update I have an issue rooting and installing TWRP (last month I was bricked), maybe because I use the last TWRP version I have before the update (currently twrp-3.3.1-1-enchilada). What is the correct process for installing TWRP and rooting again with Magisk? Do I need to get a TWRP update each time?
You have to install the latest one (3.3.18).
Reboot fastboot, type fastboot boot 'recoveryname'.img, once time you are in twrp flash the installer from the inside. Reboot to recovery again and flash magisk.
When you need to update you have two ways:
1 download the full ROM zip and place it in your main storage folder (sd card);
Update via local update but don't reboot;
Open magisk and download and install twrp a/b retention script and don't reboot yet;
Go in the magisk main page and install it as installation in the inactive slot (after OTA);
Reboot and enjoy.
2 download the full zip;
Reboot in twrp;
Flash rom + twrp installer;
Reboot to recovery;
Flash magisk;
Reboot and done.

Fastboot'ing twrp-3.3.1-2-guacamole.img?

My understanding is, if you reboot out of twrp you'll bootloop? You have to flash twrp-installer-3.3.1-2-guacamole.zip to install twrp? My question is, why? In my OP6 I could flash things from fastbooting into twrp then reboot back to oos. I may be wrong.
Try flashing twrp with this. You should be fine to flash anything in the most updated version from here and reboot with no issues. (as long as you do everything properly)

In the guide (TWRP thread) linked previously, it says: "If you will flash the installer and you are stock you need also to flash magisk or your phone will not boot again"
What you are asking seems a little different. You proposing to only fastboot boot TWRP, then flash something (Magisk?). Not sure if that will work. Even if it did, you would not have TWRP installed as a recovery. I would not consider a modded phone without a custom recover to be a desirable state.

But why? Stock recovery is close to useless. And not needed to flash OTA updates.

Can't reboot to Recovery after upgrade to Android 10

Hello everyone,
As I mentioned in the title, since I upgraded to Android 10, can't boot to recovery.
Dowloaded latest version of the Adb kit, and while issuing
adb reboot recovery
the phone reboots but goes to normal boot.
Tried manually (power + vol down etc.) and when choosing Recovery - same thing happens.
Needless to say that my laptop is authorized debug device and phone is in debug mode etc. - I have done this many times before Android 10 update.
All I try to do is to sideload the latest OTA as I did many times before because my phone is rooted and the updates do not install automatically.
Pixel (First generation)
Rooted with Magisk
Bootloader unlocked
Stock recovery (using TWRP without installing it when flashing Magisk)
Hope somebody can advise. Obviously there is something new in Android 10 which has to be set (like the need for debugging authorization for example, which I already did).
Thank you
John
Im getting a similar problem. I get stuck on th Google logo screen. I cant hard-reset, recovery mode or boot, the only things that works is th barcode.
Android 10 changed something in the ramdisk that you can't install TWRP directly on the phone. You have to boot it via PC using "fastboot boot <insert twrp image name>.img"
You can try installing twrp to ramdisk. Put twrp 3.3.1-0.img in your devices storage and then fastboot twrp 3.3.0-0 (disable pin etc first) then once it's booted go to advanced and select install to ramdisk and select the 3.3.1-0.img and it should install it. You may get a not enough storage error on 10/Q (I did) bit worth a punt. Make a back up first as usual, if no good flash a fresh factory.img and see if that cures it and then restore your apps/data etcfrom your Google back up (if you use it)
Good luck

Thank you for the advice, however as I mentioned in my original post I don't want to install TWRP permanently , and the problem is that I cannot go to the stock recovery mode which has no connection to TWRP. There is something with Android 10 which changed since 9 and I'm interested to find what. Everything worked fine before the upgrade.
Also, the option to flash factory image and restore (I also have Titanium in addition to Google backup) is a too much of a hassle. I use this phone for real, not only to play with it.
Anyway, again thank you for your input.
John
Sorry mate, re read your OP. I just tried booting into the aosp recovery and got the same issue! My guess is its magisk as I could boot into the aosp recovery prior to installing it. Re flash or restore the previous boot.img or a stock boot.img and it should boot into aosp recovery again. Magisk must be installing to or patching the aosp recovery ramdisk and stopping it booting. Other than that just fastboot twrp and use that.
Edit: it's magisk, restored original images and it booted into aosp recovery first try.
I've had no problems installing TWRP 3.3.0.0 normally after using an *.img file to get TWRP started. EDIT: and booting into it.

You are right. I did open Magisk and from the uninstall options choosed "Restore images" (no need to do complete uninstall, which is the other option). After that I was able to boot in recovery etc. I guess this is what you meant in your PS. At the end re-flashed Magisk and all is back to normal.
I will alert the Magisk team about the issue (if they are not already aware).
Case closed.
Thanks again.

Are there steps for how to install somewhere? I keep reading that it's not working on the Pixel with Android 10. Thanks

It is a mess. It works with Pixel (I have this one and can confirm) and supposedly Pixel 2. It won't work for brand new phones arriving with factory installed Android 10.
Read the following:
https://twrp.me/site/update/2019/10/23/twrp-and-android-10.html#
After that, if you want to try, go to the page below to find instructions for your device. Note that the list is by manufacturer, so if you are looking for Pixel, it is under Google.
https://twrp.me/Devices/
Just in case - backup and have the factory image for your phone handy in case something goes wrong. For google phones you can download the image and see instructions here:
https://developers.google.com/android/images
Note that I never installed TWRP permanently, so I can't say if the permanent installation will work (I think it should, but not sure). Typically I just load TWRP and use it to flash pakages, but at the end I'm keeping the stock recovery.
Hope this helps. Good luck.

Thanks. Yea from what I can tell no one has had luck actually installing it on the Pixel with Android 10 yet. I'm familiar with how to fix everything if something goes wrong. I would try but others have already tried and failed. It won't install for them.
firstly, dont use whatever ****ty platform-tools you are using, get them from here.
secondly, you dont install recovery on android 10 yet, it doenst work. you have to just boot to twrp using `fastboot boot twrp.img` once you are in bootloader mode.
