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

Aha! I did wonder but I followed the guide to the letter as I thought I might brick the phone if I risked the other imgs. I did sort it by using a different TWP file.

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.

Update with root/unlock

I cannot for the life up me update my One Plus 7 Pro from 9.5.3 to 9.5.6 with root/unlock. I've tried the Magisk install to other slot method, tried flashing in twrp, tried full OTA, tried re-installing twrp to both slots after flashing. Basically tried all the 6T methods.
How the hell do you do this? What am I doing wrong?

Not sure what you're doing wrong but what I can do is tell you my steps:
- Upgrade via stock OnePlus Updater inside system settings
- Make sure it downloads the full OTA (over 1GB file size) if you are rooted
- Let it update
- Flash the TWRP retention script found in the Magisk repo if you have TWRP and would like to keep it
- Install Magisk to inactive slot from the main screen in Magisk Manager
-Reboot and profit
Couple things to keep note of
- Uninstall all Substratum overlays before doing this
- Optional: remove lockscreen security
Personally I don't remove lockscreen security but I do uninstall Substratum overlays and I never have issues.

Anyone know how to root if I'm already on 9.5.6?

You can flash the Magisk installer zip in TWRP, which is what I did.
Or you can wait until someone posts a patched 9.5.6 boot image.

I posted the 956 magisk image in another thread but here it is again from the gm1917
https://www.dropbox.com/s/0a48lpps6ah90t3/boot956gm1917magisk.img?dl=0
Instructions
(Adb and fastboot on a PC)
(Unlock bootloader): tap build# 6x, Oem unlocking and usb debugging on, connect phone to PC, boot to recovery, "fastboot oem unlock" from PC command prompt which erases phone also, then usb debugging and advanced reboot on again
Download the patched boot image to adb directory
Install the latest version of Magisk Manager to phone
Reboot the phone in fastboot mode
Use the following command via command prompt :
fastboot flash boot boot956gm1917magisk.img
fastboot reboot
The phone will reboot into system, this may take some time be patient
Open Magisk & Install it again[Direct Install]
You've got a rooted OnePlus 7 Pro.

@schmeggy929 posted a patched boot image for the US unlocked variant that you can use for rooting and then installing TWRP. I had to switch the active slot for my device before following the instructions for the patched boot image. After getting Magisk and TWRP installed I didn't have WiFi so I wiped everything in TWRP, used the full zip for 9.5.6 followed by the TWRP installer zip, rebooted to recovery, flashed Magisk 19.2, rebooted, and everything worked great. If you get into a bootloop follow this guide

OK question does both these methods get us to the same results? Just they are different ways of doing it. Don't beat me up to bad guys.

The key is flashing a boot image that matches what you are currently running.
The second set of instructions also flash TWRP.
Both flash magisk which is essentially root.
I preferred the first method as it was simple and initially only boots to a modified image. If anything goes wrong in that step, nothing permanent has been done. The first method requires you are at least on 9.5.4 as earlier recoveries did not support booting to an image unless it was flashed.

The second instructions basically continue where mine left off by flashing TWRP recovery. He then used TWRP to repair having flashed the wrong boot image while rooting and eventually giving up and flashing the whole rom again. I think that's what happened to him.

I flashed the correct boot image, but to the wrong slot which led me to a bootloop. After fixing that problem and getting back to stock I switched slots, flashed the boot image, and didn't have WiFi (I triple checked the version was correct and others have had the issue). That's what led me to flashing the full ROM in TWRP and then Magisk.
To the OP:
I like having TWRP with a rooted device, but if you just want root then follow the first set of instructions

OK guys I'm on Verizon I just got my phone Friday and it had the update 9.5.6GM21AA for the Iphone and 7pro problem so I did it. OK now the dumb question when it says Open Magisk & Install it again. There are talking about the boot image right? I'm sorry guys I've not done this in a long time.
OK guys I googled and found what I needed thank you

With the phone only a few weeks old, we are all experimenting with what works. 1+is also releasing a lot of patches all the time so things are a moving Target. Luckily things are settling and the early adopters have sorted out how to get out of a jamb when it happens.
For others clarity open the magisk app after booting to the patched boot image i provided and do a direct install. This is that step that actually permanently patches your boot image for magisk. There are other instructions floating around that instead flash the modified image provided. Those were earlier instructions They are more hazardous in case there is a problem with the supplied image or it doesn't match your rom, or you don't flash to the correct Slot. That's what happened to the other poster but he was experienced enough to simply fix the issue. It's still a sinking feeling when it happens and you wonder how badly you've just bricked your phone. I've been there many times, lol.

I am in the exact same boat. I went through a bunch of trouble getting my phone rooted for the first time on 9.5.3. Finally got everything setup properly. 9.5.3 with root and twrp 3.3.1-20 (with decryption working).
Wanted to upgrade to 9.5.6 and have been holding off for fear of messing things up and having to wipe and start over.
Decided to go for it. Used the OP system updater. Installed 9.5.6. DID NOT REBOOT. Went to Magisk Manager and installed Magisk using the "After OTA" method. Rebooted. It booted to stock OP recovery.
Frustrated and not quite sure what to do, I went to my computer and installed twrp 3.3.1-20 using "fastboot flash boot twrp.img". I expected it was going to boot into twrp since I installed it on the current slot (A) but to my surprise it booted into system. Unfortunately I lost root, but at least i'm not at the stock recovery.
Then I decided I would try to get root using the patched image that @larsdennert posted on post 5. I went into fastboot and followed his instructions exactly. Waited for it to reboot and ended up at the stock OP recovery screen again. Since the only thing I knew how to get back into my system was flashing the twrp 3.3.1-20, I did that, rebooted, and am now back in Android, but without root.
After reading countless threads about the Slot A and B partitioning, I thought I understood it, but I must not. Or something must be setup wrong. I follow steps exactly and nothing seems to work for me.
Maybe someone can help me out. I'd like to get 9.5.6 rooted, but I am terrified to mess stuff up and have to wipe it clean again.
EDIT:
I got root! Once I got to system I had the idea to boot to recovery to see if twrp was there. Turns out it was, so I flashed Magisk from twrp and rebooted. Saw that it was rooted and direct installed Magisk again from Magisk Manager.
Man, I really have no clue how or why this worked out this way. I feel like i'm going to stay on 9.5.6 for a while out of fear of screwing something up again. This is nothing like my old One Plus 5. lol
Edit x2:
It appears my WiFi isn't working. I don't really know what to do from here.

I'm not really interested in going to a different kernel. I'm going to try to dirty flash the update again and reflash twrp and Magisk. Hopefully that will work.

Updated to 9.5.9 and now it reboots into TWRP over and over.

I followed the previously rooted guide to update to 9.5.9 and now when the phone reboots, it gets to the unlock screen and immediately tells me its shutting down and reboots back into twrp again. How do i fix this? Please help and thank you.

what method did you use (there are a million rooted guides)? did u get the correct OS OTA for you model phone? provide us more info please.

Looks like i forgot to turn off the magisk modules. I had to go into twrp and delete them all and re download the modules. silly me

I'm having a similar issue. I can't figure out what to do, but I i went and deleted all the zip files for magisk but after reinstalling magisk thru twrp, I get stuck booting to recovery everytime. I can someone help point me in the right direction?

I stuck at the same situation. Can you flashboot flash boot.img and then it can boot normally?

Same problem here.
Situation before flash: stock 9.5.8, Magisk, a number of Magisk modules
What I did:
* downloaded 9.5.9 with Oxygen Updater
* disabled Magisk modules
* rebooted
* installed 9.5.9 from the builtin System Update
* went to Magisk, installed it with After OTA
* rebooted to recovery
* installed TWRP and Magisk
* cleared Dalvik
* rebooted to system
The phone seems to start normally, but when it reaches the unlock screen it immediately goes to Power Off, then it reboots to TWRP (not power off). From TWRP I can decrypt data ok etc.
I tried reinstalling the boot loader, OTA image, TWRP, Magisk - same result. Rebooting to system from TWRP just goes back to Power Off then TWRP.

If this is any help in the future, whilst I don't have twrp, I install the updates via local update in settings > system > updates and then before reboot I go to magisk manager, and install magisk to second slot and reboot. Never had a problem and I'm on 9.5.9 now. The only modules I disable, update, or remove are the magisk ROMs available here such as no limits, as they are usually version specific.

That's exactly what I did. It landed me to the bootloop.

All you guys had to do is,
Install the full uddate zip in twrp,
Install the latest twrp zip,
Reboot recovery,
Install latest magisk,
Reboot system,
Hope this helps, cheers

Update: I can break out of the loop from TWRP > Advanced > Fix Recovery Bootloop. That lets me boot normally, but loses root. As soon as I reinstall Magisk I get back to the bootloop.

I'm in the same boat.
My twrp doesn't offer to decrypt partition_b so I cannot manually install Magisk on the new partition.

This seems to be a common problem when updating rooted Oneplus 7 pro and I haven't found a update guide which actually works every time. Last update to 9.5.8 I had the same issue where I couldn't get into oxygen os because it turned itself off and when twrp opened I couldn't decrypt the data. I couldn't find a solution last time and I had to full wipe and start from scratch. Now I don't want the same to happen so I hope someone can post a guide how to do the update successfully.

Works every time, the same way I have been doing for both 6T and 7 Pro.

Sometimes you might be on the wrong active slot, you can change this by using fastboot set_active a or fastboot set_active b. TWRP seems to like changing your slot but will tell you when it does. If you're getting stuck try changing slot and booting.

I tried that too. When I switch to the other slot I get to a menu where I can only wipe data, reboot to boot loader, or reboot to recovery. Not particularly useful.

Hey guys!
I'm having the same problem. No matter how I try to update it will reboot to stock recovery.
I was wondering if any of you have /Data converted to f2fs? Maybe it could be culprit...

What I had to do here was go to fastboot mode and flash twrp img. Then in TWRP I flash the TWRP zip file and magisk and rebooted. All good

Alright so I fixed mine. I went and just removed all the modules while I was in twrp. To do that go to Advanced, then file manager or whatever it says, find the adb folder and from there look for a folder named Modules and just delete them all. From there just reinstall magisk through twrp and it should all work.

Thank you sir, this fixed it for me, too. So the missing link was that Magisk modules have to be removed completely, not just disabled, before upgrading. Removing all directories except .core from /data/adb/modules allows the phone to boot normally, with Magisk enabled.

OnePlus 7 Pro Flashing doesn't work properly

Hey guys,
so first of all I wanna let you know that my device is not bricked or something (it was a couple of times though).
But let's get started with my issue. For me, personally, I have experienced that the slot system (A/B Slot) doesn't work that good. I had a OnePlus 3T before and I never had any problems with flashing, but now...
My impression is that it's a lot easier to brick its' device than before. Every time I want to flash a new OS I gotta use the msmtool.
1. I boot to recovery mode through the OS
2. I boot to fastboot trough the OOS stock recovery
3. I try to flash TWRP to erase the system
4. Flashing works, but I can no longer boot into recovery mode
5. I have a bootloop (fastboot mode only)
6. I have to use that msmtool
7. I have some old OOS (9.5.5 or something)
8. I unlock the bootloader through the OS & fastboot
9. I boot into TWRP, delete everything and flash another ROM
10. Everything works and the cicle begins again​
I really don't know why I'm always stuck in that bootloop... Maybe you guys could help me and give me your personal opinion on the slot system?

I totally know that feeling. I started with a tmo op7p, flashed international, unlocked bootloader, try to boot TWRP, and nope. Switch slot, it works. Flash it, great. Make a backup with TWRP of my working system, flash ROMaur, won't do anything but boot to TWRP. Open TWRP file manager and every file on internal storage is a ton of folders with jumbled strings of letters and numbers for names. MSM tool back to intl stock, try lineage... Nope. Keeps telling me to do a factory reset. I did, but I do another and still boot loop. MSM to intl, try other roms, same outcome.
I can unlock my bootloader and root it and run intl stock but that's it.

Doing it wrong.
If you are currently rooted and a new OS comes out you can do the following and you don't need to flash with TWRP or use a computer.
1. Download the full OTA. You can use Oxygen updater to do that or use a link in the stock ROM section on this site.
2. Make sure you have the Magisk and the TWRP zip on the phone.
3. Do a local update in the system area but do not reboot.
4. Launch Magisk manager and select install.
5. Use the OTA install option to inactive slot.
6. Now you can reboot. You have installed the new OS and root also.
7. Once rebooted do another local install. This will install in the slot that you were just running. It will fail the first time, but work the second time.
8. Repeat 4.
9. Repeat 5.
10 . Repeat 6.
You now have both slots with the same OS and rooted.
If you want to install TWRP.
Launch Magisk and install the TWRP zip.
Reboot into recovery. This is important because you cannot boot in slot with TWRP unless Magisk in installed.
Now flash the Magisk image file.
Now in TWRP select the other slot and reboot into recovery.
In recovery install Magisk image to this slot.
Now you have TWRP and Magisk in both slots.
I have done it that way since 9.5.7 and have not had an issue.

Irrelevant ISH, but ever had that one bootloop where it only bootloops at the "Warning Bootloader unlocked screen" constantly? When I try to access fastboot, it'll just go straight to recovery without even waiting for input (to my luck, of course, until I had to uninstall magisk in full, reinstall, make sure TWRP was reflashed and did the "Fix recovery bootloop", though that wasn't the seemingly the issue). The issue got resolved, but it was very scary for that to have happened as soon as i enabled sudohide (I always had it work, but with huge problems, but never enough to bootloop me to death)

If you install TWRP on a 7 Pro without installing Magisk you will absolutely boot loop. If you wipe the system in one slot and have a differing ROM from the active slot you can in fact boot loop. Although the systems are different, the settings between the systems are shared.

Sorry to say, but nothing about those steps is correct. Follow some guides in the guides section to get aquatinted with the A/B system

You are absolutely incorrect.
When going from 9.5.10 to 9.5.11 and all my previous upgrades it has been:
1. Local install of the new OS with a full OTA since I am rooted.
2. Do not reboot.
3. Install Magisk to inactive slot.
4. Reboot (Slot will automatically switch to the one recently updated).
5. Local install of OS into the other slot, fails first time, do it again.
6. Install Magisk into inactive slot.
7. Reboot. (Slot will switch to recently updated slot).
8. Both slots now have latest OS and are rooted.
You can also install TWRP if you like.
No computer needed.
This works.

When going from 9.5.10 to 9.5.11 and all my previous upgrades it has been:
1. Local install of the new OS with a full OTA since I am rooted.
2. Do not reboot.
3. Install Magisk to inactive slot.
4. Reboot (Slot will automatically switch to the one recently updated).
5. Local install of OS into the other slot, fails first time, do it again.
6. Install Magisk into inactive slot.
7. Reboot. (Slot will switch to recently updated slot).
8. Both slots now have latest OS and are rooted.
This works.

That's completely unnecessary and just avoiding the purpose of the a/b system.
All it would take is:
1. Local install
2. Install magisk to inactive slot

Issues getting root back after Android 11 Update OP6

Hey, after installing android 11 on my Oneplus 6 I have servere issues on getting root back.
Both methods I used result in a stuck boot.
Method 1: fastboot boot twrp, then install magisk.zip (tried with both 21.4 (last with a zip) and the renamed 23.0 (from apk to zip)
Method 2: Extracted boot.img from my OTA update, then patched with magisk 23.0.
Flashed the new boot.img -with fastboot -with twrp both result in a stuck boot.
Suprisingly flashing the extracted boot.img from the OTA boots fine, but that image is without magisk
Update: I have extracted the boot.img directly from the phone, patched it and it still doesn't work

I've also tried fastboot boot twrp with a variety of versions of twrp after upgrading to 11.1.1.1 but with no success.
If someone could recommend a verified way to root a op6 with 11.1.1.1 I'd appreciate it

twrp actually works, but after flashing magisk or flashing a magisk boot.img it breaks. I have a working version here
Ping me if you get magisk working

I can confirm the TWRP-3.5.2-enchilada-Nebrassy-2.img run on my OP6 without any issue and allowed my to install the latest magisk, giving me a fully functioning root for my 11.1.1.1 ROM. Thanks for the help

To remember!

Which installation method of magisk did you use?
How long did you wait after first boot?

I downloaded the full 11.1.1.1 ROM as I was upgrading from a previous rooted 10.3.x version. I placed this file in the phones root directory and use the "local upgrade" feature.
When that completed I rebooted the phone a few times just to make sure everything was working as expected. I usually waited 1-2 minutes before rebooting every time.
Next I placed the latest magisk version file into the root of the phone rebooted into the bootloader and performed fastboot boot TWRP-3.5.2-enchilada-Nebrassy-2.img which booted into the TWRP as expected. Then I installed the magisk.zip and rebooted the phone into a nice newly rooted magisk environment. Tbh I didn't wait anymore 10-20 seconds to reboot after installing magisk while in TWRP.
I hope that's helpful for you

Thanks for the reply, as a last question: Which magisk version did you use (could you link i?t). I assume you took the magisk v23 apk and renamed it to .zip? or what did you do?

Yes. I used the latest canary build of magisk and simply renamed it to magisk.zip

Hmm, I perfectly copied your instructions and still get a bootloop. Even reflashed 11.1.1.1 again. Might be time for a reset

Do you actually get a bootloop or it just gets stuck in the unlocked bootloader warning screen?
Mine hangs there for several minutes before booting, I reflashed several times because of it but all I had to do is wait.

I leave the "bootloader unlocked" screen and the rotating "circle" animation plays. I even can connect via adb logcat to see the boot logs (but I do not understand them, though they clearly loop)

is there a zip version of TWRP-3.5.2-enchilada-Nebrassy-2 available that I can flash or can i flash the standard twrp latest zip after booting in to the nebrassy recovery so that it is permanant recovery?
Also can I flash the latest 23 relase of magisk or does it have to be the canary?
I was able to successfully boot in to the nebrassy recovery but i don't want to get in to a permanent bootloop if the standard twrp zip will break things after flashing or the stable relase of magisk will get me in to a bootloop
Thanks @UraniumDonut !

The twrp image should have a button in twrp called "install current twrp to recovery" or similar. With magisk I cannot help you as I have bootloops with every version of magisk , but @Thratchen had success with the canary version (I didn't)

Try to flash the full update zip with twrp, it will flash to both partitions, then try to flash latest magisk renamed apk in twrp.

Thanks, I’ll try. A few questions:
Wipe dalvik after flash?
Boot into system or instant flash magisk?
Wipe dalvik after magisk?
Which magisk?(canary or 23.0)?
Thanks!

Thhank @UraniumDonut - that worked - I have never before used that method and honestly didn't even know about it. I use the official documented twrp way which is to first fastboot in to twrp and then install the zip file which has to be located on the phone file system. This method seems a lot easier!
As to magisk, I usually flash that from twrp using the zip file method and never have had any issues. But with all the issues surrounding oos 11 I am playing it safe as I don't want to get in to a boot loop. Will do some more research before I try something. But thanks to you I have made 1 step forward progress!

I wiped
No need to boot first
Wiping once is enough
I'm using 23
I did not install twrp at all, just booted it, flashed Ota and magisk and reboot.

I'm out of ideas. I followed your guide exactly.
Flashed 11.1.1.1 OTA.zip
The log said "installing to inactive slot _b, reboot recovery to flash more zips"
I wiped dalvik,
I rebooted into recovery slot b (I didnt boot into system)
I installed magisk 23.0 APK renamed to zip. It installed into slot b.
I did not wipe dalvik.
I rebooted into system.
I still get a stuck boot (OnePlus circles rotating)
Bonus: after "fastboot flash boot stock_boot.img" it boots fine (but no root)
I never installed TWRP, just "fastboot boot TWRP"
I understand nothing

Just for reference here
