Android 11 possible boot loop recovery - OnePlus 8 Pro Guides, News, & Discussion

I upgraded my 8 Pro to Android 11 (11.0.1.1 IN11BA) and was able to keep root using Magisk's feature "patch to inactive slot".
However, after two-three reboots on Android 11 (activating some Magisk modules, and installing some apps) the phone suddenly got stuck in a boot loop.
I figured it might be helpful for someone else to know how I recovered my phone without losing any data.
First, I needed to get access to the phone, so I entered fastboot mode by pressing volume button during boot.
Then I downloaded my firmware dump from XDA and patched the recovery.img using this tutorial:
https://forum.xda-developers.com/on...ecovery-oxygen-os-stock-recovery-adb-t4084487
My patched recovery image is linked in post #46 of that thread.
I fastboot flashed (since fastboot boot didn't work) the recovery image to my phone and rebooted to recovery.
Using the patched recovery image I was able to get root access to all partitions, including /data.
When investigating a boot loop on this phone I found the following path useful:
Code:
/mnt/vendor/op2/boot_log/
In that directory you will find logs from the last five or so boots, and at the end of the "android_boot.log" file I found this message:
Code:
StagingManager: Failed to install sessionId: 664232199 Error: APEX activation failed. Check logcat messages from apexd for more information.
I'm not familiar with "StagingManager" and "APEX sessions", but after digging through PackageInstallerService.java it seems this error is caused by some kind of app installation that is done during reboots (now I'm guessing).
Anyway, I didn't care much about the reason for the error, I just wanted my data back, so I deleted this file (containing the failed APEX session):
Code:
/data/system/install_sessions.xml
After deleting that file I was able to boot my system and access all my data again!

Nvm..

Don't need with the recovery is still intact so no need to touch it you'll cause more issues.
So you got the bootloop when you installed some magisk modules.

My boot loop was not caused by a magisk module. I did remove all magisk modules and even re-flashed stock boot.img, but that did not help.
adb wait-for-device didn't work since the boot loop occurred before adbd start (it seemed).
And, I absolutely didn't want to wipe my system from recovery.

No worries man I got the wrong end of the stick. Dw

I've Updated and it's stuck at bootloop . What I can do?
My mobile is the T-Mobile version that I have converted to Android 10 International.

this will help someone, for sure
nice work writing down your expirience

Just to be clear with what I said earlier.
If it fails after a magisk module installation then just boot to safe mode then reboot and all magisk modules will be deactivated.
According your post that's how it happened.
"However, after two-three reboots on Android 11 (activating some Magisk modules, and installing some apps) the phone suddenly got stuck in a boot loop"
1. Safe mode
2. Reboot
3. Remove last module and activate other modules.
Done
PS: I do a lot of module testing and this is my safety net so yes it 100% works.
You're method will help people for sure though

just so you know, you just saved my ass.
i expirienced the same problem
i did cleard data of google, google services, google framework and google play store
after that - google downloaded some kind of update and that's it
at android boot log there was same error
adb shell rm /data/system/install_sessions.xml using modded stock recovery rocks

Android 8 update with FlashFire breaks TWRP or TWRP boot-loop

Hi everyone,
I tried to update my rooted Pixel C with Android 8 and TWRP 3.1.0.0 from August build to September build with FlashFire.
All of the following have I done on my Nexus 5x as well and it worked as a charm there.
Therefore i dl'd the corresponding zip-file from google dev page and started the update with FF. It said to me it can update the boot, system, recovery and vendor partition so I unchecked the recovery partition only to keep TWRP. I also told FF it should include SuperSU again to root the new Android.
After the update the device was unrooted, so i tried to start into recovery to install superSU manually. But TWRP was gone and i get everytime the android on the back with the text "no command".
Therefore I tried to flash TWRP with NRT again. But after the flash the device always starts into TWRP and Android isn't starting anymore.
I can use NRT again to flash Android without loosing my data but than TWRP is gone again.
So either the device always starts into TWRP or I have no recovery installed.
Anyone an idea what i can do to flash TWRP again and to fix the boot order or whats broken than?
Regards,
flattervieh
I don't have the C but here's what I would try. First, have your device booting normally with the stock recovery. Then use fastboot to boot into TWRP, not flash it. When it boots into TWRP then flash supersu. From TWRP then boot back into the bootloader and then flash TWRP with fastboot.
Flash the latest (beta?) TWRP. It allows reading the encrypted data folder.
Short notice, i'm still struggling with the problem.
In the meantime I tried the following:
1. I temporarely booted TWRP 3.1.0.0, with this version I was not able to encrypt the data partion (always invalid key) but I was able to see the system partition and I installed SuperSU. After that i restarted into the bootloader and flashed TWRP 3.1.0.0.
This led to the same phenomenon, that my pixel always boots into TWRP and not into Android itself.
2. Same thing as before but with TWRP 3.1.1.1.
With this version I was able to see the size of the data partition, but I was also not able to read or write onto it. (Again invalid code) I installed SuperSU and made a device restart without flashing TWRP 3.1.1.1.
This led to a totally softbricked device with a boot into "no command" screen.
After flashing Android again via fastboot Android starts correctly and I can use the device but root is still not working.
Regards
I'm not sure why twrp isn't sticking. But the android on its back with "no command"is the stock recovery. To get into it simultaneously press and release the power and vol up keys. You might have to try it a few times as the timing can be very finicky. From there you can boot into the system, you don't need to flash the factory image and start all over.

Android 8.1 + Magisk

Hi!
Does Magisk (including root, etc.) work flawlessly on a Pixel C with Android 8.1? Or is better to stay with 8.0 and wait a little bit?
Thanks in advance and kind regards,
star3141.
It works, initially it would force close but now seems stable. I used v14.5 beta.
On the other hand super su by chainfire does not work. Would flash but app missing. Downloading from play store and updating binaries through app causes boot loop.
v14.5 works perfectly here, no problems at all.
Hi!
Thanks for the replies. Maybe I will give it a try at Christmas or alternatively wait for the first update of 8.1 in January.
Hello!
Today, I gave it a try but unfortunately faced some kind of total reflection.
1. I downloaded and flashed the latest android factory image (ryu-opm1.171019.016 = 8.1 from Feb. 2018) from Google.
2. I downloaded and booted (without installing) twrp-3.2.1-0-dragon by means of "fastboot boot twrp-3.2.1-0-dragon.img"
3. In TWRP I mounted the system partition rw
However, after mounting the system partition rw, android won't boot into the system anymore. I am alway getting the green android guy laying on its back with "No command". When I boot into TWRP and mount /system in ro-mode, then will boot afterwards without any problems. So the problem must be related to mounting /system in rw-mode by TWRP.
I have also tried twrp-3.0.0-0-dragon-ryu-02112016-1.img, which worked on my previous 8.0 installation, but it won't work in this 8.1 release anymore.
Any ideas how to get rid of this problem?
Thanks in advance and kind regards,
star3141.
Hello!
I found a solution!
If someone else suffers from similar problems then try the following which hopefully will fix everything: :fingers-crossed:
1. Download and flash the latest (in my case Android 8.1 from Feb. 2018) android factory image from Google.
2. Complete the standard android setup procedure and, when the system is up and running, enable "USB debugging" in the "Developer Options".
3. Restart your device in bootloader mode by "adb reboot bootloader".
4. Format your /data partition by "fastboot format userdata" to remove the filesystem encryption.
5. Download the latest TWRP (in my case "twrp-3.2.1-0-dragon.img") and start it by "fastboot boot twrp-3.2.1-0-dragon.img".
6. In TWRP mount /system in rw-mode and just to be sure check if the /data partition can be accessed. If not, just wipe/format it as ext4 again.
7. Download the latest Magisk (in my case "Magisk-v15.3.zip") and sideload it by "adb sideload Magisk-v15.3.zip" in TWRP.
8. Reboot into the android system and install the Magisk app (in my case "MagiskManager-v5.5.5.apk")
9 Viola! Enjoy a working and rooted android 8.1. :victory:
Kind regards,
star3141.
didn't have any problems with magisk 15.3 on 8.1 but with 16.0 the pixel won't boot anymore (stays at the google logo, not even reaching the bootaniamtion). anyone else having this issue? after flashing boot-image and reinstalling magisk 15.3 it works fine again...
For me as well, get 16.0 not to run, Bootloop
Yep, same here, then I bricked it restoring a nandroid backup where it destroyed system, then I couldn't get past encryption password in TWRP. So it's been one of those days...

did you already try "default_password" (without quotes of course)? had this issue too some time ago after restoring a nandroid – reflashing twrp via fastboot and decrypting with default_password helped

Yes, tried that as well. I think I just corrupted the system, wiped data and system in trying to get around the Magisk problem.

Hm, as long as you still have fastboot access, I would try to manually flash partiotions (system, vendor etc), flash twrp, install masgisk 15.3, start from scratch and restore the apps with titanium backup (hopfully you have a backup!). as long as its not a hard brick, it's all fixable

Oh, I'm back to normal now. I couldn't get it to connect to PC as all I had was fastboot and recovery. I discovered the only way to get adb/fastboot connection from PC was to go into TWRP and ADB Sideload. Once that was established it made the connection and I installed 8.1 from the command line with the flash-all.bat.
Then I could restore the nandroid. All is well now, thanks.
good to hear!
Same problem here with 16.0. Seems to be either a bug or some kind of incompatibility with the pixel c.
Magisk 16 and Pixel C
Any word on resolution of the boot loop issue?
Reflash + downgrade to 15.3 seems the only working solution at the moment.
I have re-rooted using Magisk 15.3 from SuperSu. Am I OK updating to 16.0 through Magisk, or should I try 16.3?

16.0 causes a boot loop. Somebody else had an issue with 16.3. I'd stay with 15.3. Just turn off update notifications and Magisk won't bother you.

Phone bricked. "Unable to mount /system (structure needs cleaning)" in twrp

Okay so to begin, my device is a us cellular moto z2 force. I had rooted my device with magisk using twrp successfully and everything was working fine.
Where i ran into problems was when i tried to figure out how to get a new boot animation to work. Originally I tried using a rooted file manager to edit /oem/media/ for the boot animation there. I had already placed a new boot animation in /system/media and it still showed the normal boot animation on boot, so i looked it up and /oem/media seemed to be where it checks first.
I tried to use the twrp file manager to rename the file in /oem/media since the root file manager was not working.
What happened was that it still showed the normal boot animation on start up and while twrp showed the one in /oem/media to be renamed, the root file manager did not. This is where i got confused.
I ended up looking around in twrp some more to try and figure out why when i noticed an /oem in /system. I thought (somewhat badly) that this may have been the place where the boot-animation was, even though I couldn't see it. This is the part where everything went wrong.
I deleted /system/syestem/oem because i didn't see the bootanimation.zip in it to delete individually, i just deleted the whole thing because of something i saw about /oem not being needed.
After this my phone still booted but a notification came up saying "finishing updating android" and I knew i did something wrong. Also the check in magisk came back with basic integrity but not the other one. I also noticed magisk was not installed anymore.
This is when I decided to restore from a backup in twrp and bricked my phone. After restoring I restarted my phone and it got stuck in a loop of the screen fromthis guide on how to remove the boot loader unlocked splash screen, which was working fine before.
Any help would be appreciated.
Okay so Managed to boot by switching partitions and clearing cache and data in twrp.
Now my issue, SafetyNet ctsprofile and basic integrity are both false, and I still have no idea how to change the boot animation without bricking my device.
So I was able to download magisk manager then re-download install the magisk framework directly from the app. It seems it was on some middle ground where it didn't work properly but I still had root and could grant superuser to apps, but couldn't install modules or have safety net.
Still have not figured out how to change bootanimation or anything in /oem without it coming right back on boot or while android is running, may give up if it ends up taking too long.
You should use a flashall to get yourself back to stock and unbroken. If you cant find the flashall for usc here google for Nash flashall, its definitely out there. I've been messing with OEM today and it looks like dm-verity is undoing all of our changes.

can't install Magisk

tried to replace SuperSU with Magisk via TWRP.
Magisk won't take by itself.
Removed SuperSU. Tried again. Still NG.
"adb reboot recovery" back to TWRP and flashed SuperSU. I have root back, though I don't see SuperSU in the app drawer.
The info to install Magisk leave a bit to be desired.
"install manually" what does that mean?
Remove root (SuperSU) seems to prevent one from installing Magisk, though I did "adb reboot recovery" to get the re-install of SuperSU done.
In the long run, I want to update our other H811 to 20x from 20q. Thats' what started me down this track.
Any input?
Did Magusk Zip Got Trough without any issues in TWRP?
Did you have the magisk App in drawer after flashing Magisk?
Magisk manager is sometimes an older version, so you have to go to magisk manager (app) open ist and click on upgrade or install upgrade.
sometimes my device needed 2installations. one in twrp an another in MAgisk app. but both were v16.0 zip.
no & no. "updater process ended with ERROR: 1
Error installing zip file '/external_sd/Magisk-v16.0.zip'
Tried installing Magisk Manager, which went ok. And then Magisk from that. Error.
"Boot image patched by other programs (SuperSU, perhaps?)
Please restore stock boot image."
So I ran the script that removes SuperSU.
Tried install again from MM.
"Select stock boot image dump in .img or .img.tar format."
No idea where to find that.
Tried this method.
NG. SuperSU doesn't show in app drawer, though it appears to be working as I can reboot recovery from the phone without going into Terminal and adb.

You should Always search the TWRP errors you have, that gives you more info.
Error 1 means on your system partition is not enough space anymore, so delete or Freeze some bloatware/apps and it should go trough.
boot.IMG files are containt in KDZ (firmware files).
Maybe you should visit https://******************/
and read trouh installation (with pictures) for better understanding.

went and posted in digeridoohan original thread.
https://forum.xda-developers.com/showpost.php?p=76980632&postcount=25580
all is well.. thanks very for the help. and I installed the Xposed module that works with TextAid and MM.
also your link won't doesn't seem to work. I've found that a I've had to use shortened links of late or they don't fire on XDA.
Guys I can't run Magisk on my LG G4 H815 with Nougat v29a. After removing Supersu and flashing magisk 17.1 with twrp, the phone doesn't boot normally. It reboots recovery when I click reboot system. It always reboot recovery. I don't know why.
Do you have any Idea?

[SOLVED] TWRP does not decrypt /sdcard; 'fastboot boot recovery' doesn't work

Hi everyone. I hope this is the right forum for this question.
Edit: I found the thread for TWRP and it says there is a known issue with decryption for Android 10. I think that is the root of my problems. I'm going to try to downgrade to Android 9 since I hate Android 10 anyway. It was causing all sorts of problems with my phone...random reboots, etc.
I have a Pixel 3 XL running the latest version of Android (image-crosshatch-qp1a.191005.007). I want to root it, but am having problems with TWRP.
I have the google usb drivers and adb and fastboot. I downloaded them all through the latest version of Android Studio.
I then used the official guide from twrprecovery.me (slash) google-pixel-3-xl/ to try to install TWRP. When I follow that guide I have 2 issues.
First, the '.\fastboot boot recovery recovery.img' command does not work. I get this error:
Code:
fastboot: error: cannot load 'recovery': No such file or directory
I am able to use .\fastboot boot recovery.img. When I do that I encounter the second problem.
Second, if I boot into TWRP using the command .\fastboot boot recovery.img, the file system is encrypted. It shows no data in the /sdcard folder and it shows the available storage space in Internal Storage as 0MB.
I've seen a lot of threads about that, but none of the suggestions work (I.e., setting a pin, setting a password, disabling home screen security all together, setting the phone to require a password or pin on boot (that option isn't available on the Pixel 3 XL), etc).
What I have been able to do is use TWRP to chmod 755 the /sdcard folder and then use adb push to transfer the recovery.img file. This was more of a test since I didn't expect it to actually be able to flash it. To my surprise, that worked, even though it couldn't mount any of the partitions. Of course, doing it that way removed the OS because it was flashing it to System not Recovery (I think...this is the first Pixel I've installed TWRP on).
That wasn't an issue since unlocking the bootloader had already wiped all my data. I just reinstalled the stock OS. After reinstalling the stock OS I just see a dead Android when I boot to recovery. I think that's either because A) TWRP was never installed to the recovery partition, or B) the stock OS overwrote it.
To summarize, I need to 1) boot into recovery so I can install recovery.img without wiping the OS, and 2) decrypt the file system.
Can anyone help me out?
Thanks
