Android 10 root issues? - Google Pixel 2 Questions & Answers

I updated my pixel 2 to the Android 10 stable release this evening .
First thing I did afterwards was root with magisk .
I pulled the boot file, patched it and flashed it.
I opened magisk everything is checked , used Root check app. That came back positive.
However when I try to modify my host file and install my custom host file I get error messages saying " Can't delete file" .
I tried both root explorer and solid explorer both apps have root access . But can't modify the system files.
I'm starting to thing that I'm getting a false positive on root or something has changed in Android 10 and we can no longer modify system files.
I tried both the stable version and canary version builds of magisk . Both say that I'm rooted but the issue persists .

I saw on another thread after you boot twrp in adb, mount everything as read only and then reinstall twrp and magisk zips thru the recovery. I used most recent versions of twrp and magisk and didn't need to alter the zips in any way. I'll see if I can find the thread....

Couldn't link the thread, so here's a ss

I'm having no problem with IanMacd Magisk repo, link below, check readme on bottom of page for instructions on how to configure Magisk for a custom repo.

You can just boot the recovery if you don't want to install it permanently.

Thank you for all the replies, turns out I was rooted but I just couldn't write to system. I ended up installing energized pro module for magisk to modify my host file. No more ads lol

I could also root my pixel 2 with canary_magisk but, although its says rooted, some apps say couldn't find the root binary's. Going back to Android 9

So I seem to have an issue with solid explorer. I go in and remove gmail and other google stuff I don't use typically. Solid gets permissions and when I go to delete the gmail folder it errors out. Not certain if this is a root issue with Magisk or perhaps more likely an issue with apps that need root...

Recent root problems on my L04 Marshmallow B820

I had the problem, I couldn't root my phone after the update from B521 to the latest B820 version.
I tried out SuperSu versions 2.65 till 2.74.
After rooting through TWRP, I always got bootloops and after unrooting the system starts normally.
As a last try, I looked into the install script and set the "SYSTEMLESS" var to "true".
Now I've got a rooted and starting phone.
So I think there must be a problem, at least for me, with automatically detecting a systemless installable Android version in SuperSu from chainfire at Honor 6, as I understand.
Did anyone else have that problem?
I added SYSTEMLESS=true in /META-INF/com/google/android/update-binary within SuperSu-v2.65.zip, just as described there, but it should defaults to true after proper detecting without this.
At my B521 system, I used SuperSu version 2.52, which worked there and wasn't booting at Marshmallow, too.
Install 2.62

The Multi Tool says for TWRP L02 and L12, can I also install it on L04?
I've installed SuperSu 2.74 via fastboot/TWRP, but as I wrote, only with an modified updater-script, the system boots up. (for me, not sure why and maybe this can help others)

I think I have exactly the same issue, could you upload your modified supersu.zip for me or walk me through the modifications?
That'd be swell.

Have tested it today with latest stable SuperSu, which is v2.76-20160630161323.
-> open the archive with an archive-manager
-> go to /META-INF/com/google/android/ directory
-> edit update-binary with a text editor (your text editor should respect linux line breaks (LF), so if you're on windows, you have to make sure this, I think)
-> after the commented section(all lines with a # beginning), where you can read about possible system vars and beyond,
you have to set the SYSTEMLESS variable to true like in the following example of code:
Code:
...
# if needed. It must replace the input file and return a 0 exit code.
[COLOR="Red"]SYSTEMLESS=true[/COLOR]
OUTFD=$2
...
Line 2, you have to insert to achieve an systemless installation, which seems to be the only way for you and me to make it work.
Please make sure to pay attention to upper/lower case, because otherwise it will fail.
-> save the updated zip and install it via TWRP, e.g. via sideload
Hope, this was usefully.
Note: This is only usefull for Marshmallow as described in the file, because it will not work below.
If you leave TWRP afterwards, e.g. for reboot and it asks you for installing root, click on "Do not install".

SuperSU - which version for MM B820/B831? [SOLUTION]

Does anybody know which version of SuperSU is working on B820/B831?
I tried the one on multitool -> No root access.
Then I tried 2.62, 2.65, 2.67, 2.76 -> None of them are working.
2.62 works fine

Are you on b831?
Do I have to "unroot" before I "install" another SuperSU-Version? How do I do that (restore)?
Have 2.76 on B820.
Did you successfully install it and have it in your launcher? If so, try to allow every root access without promt. If it works then I have a solution for you.

Thanks for your help!!!
At first I tried to install it with mulitool. There was a symbol then, but when I started it there was a error message. When I tried to install other versions there was no installed supersu-app and I couldn't install it from Googleplaystore or manually.

Ok, weird. Just to make sure: You download this zip file:
https://download.chainfire.eu/969/SuperSU/UPDATE-SuperSU-v2.76-20160630161323.zip
(from the xda-thread)
Copy it where ever you find it (like sd-card). Start into TWRP recovery. Select Flash/Install (dont remember the exact menu entry), choose the zip file, let it install.
After that TWRP will probably ask you if it should root your phone, because it seems not to be rooted. Dont do that! Dont exactly know why, but you definitly dont need that, TWRP is wrong here.
PS: Multitool doesnt have EMUI 4.0 for L04 yet last time I checked
Yeah. I tried it again 5 min. ago. I installed it 2 times. Still no app.
Maybe it has something to do with b831?
What do you want to say me with the PS?
I installed a B831-image I found on the Internet. Everything works so far!

Pixel 3 rooted with Magisk - OTA is being downloaded?

My Pixel 3 is rooted with Magisk, but I did not install TWRP.
Root is available:

"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Yet, the phone is offering an update:
Since I took this screenshot, the download has completed, and it is offering to install it.
My understanding is that OTA would not happen if the phone is bootloader unlocked and rooted.
Should I let it install this update? How can I find out exactly which update it is? I'm assuming it would be (PQ3A.190605.003, Jun 2019), but how can I confirm?
Where is this 1.2 Gb file stored on the phone once it downloads? I found posts saying it was at root level in folder /cache, but it is not there. Maybe it moved for Android 9? I tried to use Solid Explorer to find files > 1 Gb, but it did not find anything.
I was also surprised today, but let it install. Lost the root afterwards.

Did you have any issues re-establishing root with Magisk after installing the update?
Which version of Magisk? Latest 19.3?

Rebooted into bootloader, fastboot TWRP, flashed latest 19.3 and that's it. Everything is back to normal

As the screenshot you provided implies, your boot partition seems corrupted.
Trying to figure out why can come at a later time, in the meantime try flashing a boot.img extracted from your current ROM (i.e a TWRP backup) or stock firmware (if you're on Stock). Using TWRP or fastboot should solve this issue.

Since I'm stuck on fastboot there's no way to extract it, so i just flashed the ROM zip file, and it worked. Thank You

So, I understood that for whatever reason you don't have the red-framed button in your Magisk app as shown in my screenshot.

Did you try the uninstallation instruction that topjohnwu provides in his Github here (I mean the second sentence of the paragraph):
Installation
The Magic Mask for Android
topjohnwu.github.io
Last but not least, the following thread is monitored by highly knowledgable members who are certainly better suited to support you than me, although a search there could probably already provide a solution:
Magisk General Support / Discussion
This is the place for general support and discussion regarding "Public Releases", which includes both stable and beta releases. All information, including troubleshoot guides and notes, are in the Announcement Thread

@marcwsa
You uninstall Magisk from within Magisk Manager app.
Apologies - but I am new to this and I think I may have bricked my phone now.
I did a complete wipe and now when it asks to reboot it says "No OS installed"
I fortunately still have access to the phone using USB to my PC so can transfer an image to the phone still. It ends up in /sdcard
BUT when I say install and point to the Pixel image file it goes all the way to the end and then on reboot says
No OS Installed Are you
sure you wish to reboot?

No uninstall option on my APP - that's the problem - but no worries anymore, I think I bricked my phone in any case :-(
