Unable to reroot emui 9.0 - Huawei P20 Pro Questions & Answers

I updated to build 251 and then was able to root normally.
However, I installed a module which prevented me from booting with root.
Is there a way to fix this?

Boot to recovery and magisk will be used to boot..
So try it with ADB.
ADB reboot recovery
Let the phone reboot.
As it has magisk installed it will not open twrp anymore . But it will use the image installed for magisk, from your perspective you'll just see the phone reboot.
Once you boot up you'll have root access..
Essentially what this means is you would have to boot to recovery to do a normal reboot if you wish to retain root access.

It refused to boot. Anyway, I dont think there is a way to fix this on emui9 if you have installed a faulty magisk module that results in device being unable to boot with root.
I had to do a complete factory reset in order to get it working again.

Just allow it to boot without root. Remove the module and magisk and reinstall.

snapchat fail login after root?

Hey everybody I rooted my device this morning, and I was setting everything up again since it gets wiped during the process. So finally I come and try to login in to Snapchat and it says something similar to "log in has failed please try again later" anybody have this problem or a way to fix it? Thanks in advance!
Snapchat checks for root and purposely prevents you from logging in if it find it. If you rooted with SuperSU, try installing Chainfire's SUHide. Otherwise, if you rooted with Magisk, enable MagiskHide in Magisk Manager.
I usually unroot with SU and login while unrooted, then flash whatever SU zip used to root again. It should work and you'll stay logged in.

OMG thank you so much that was so easy!!!!
magisk is better though because you can still use android pay and mobile banking applications.
If I throw on a custom ROM after wiping will I need to do this process again?
Yes. Unless the custom ROM has built-in root, you will have to flash SuperSU or Magisk every time you flash a ROM (including updating the same ROM to a newer version). Flashing a ROM replaces the files required for root in the /system or /boot partition.

I shouldnt brick if i have to loose root and reflash super SU when I'm running a rom right? Sorry for all the questions
Suddenly losing root without a reasonable explanation would be a cause for concern and should merit further investigation.
However, simply flashing SuperSU after flashing a ROM (dirty or clean flash) shouldn't cause any issues.

Yeah cos I would need to flash the ROM, then sign in to Snapchat, then go back to TWRP and flash super SU
Honestly, I would just recommend you to use Magisk to root. You can have it hide both root and itself from apps like Snapchat. Better yet, since Magisk Manager is not a system app, it will survive updates through dirty flashes. This means that after the initial set up, any time you dirty flash a ROM and then Magisk immediately afterwards, root is already set up and hidden from Snapchat the first time you boot up.
Also, be careful with flashing a ROM without rooting immediately. ROMs like OOS will either replace TWRP with stock recovery or trigger dm-verity if you don't root immediately after clean flashing.

So I just have to download magisk manager and it should re-do everything for me if I understand correctly right?

You will have to remove all traces of SuperSU before flashing Magisk. If Magisk detects systemless SuperSU already present on your phone, it won't root it with its own method (and therefore cannot hide root from other apps). The easiest way to install Magisk over SuperSU is just to dirty flash your current ROM and then immediately flash Magisk v11.1 (don't forget to wipe cache/dalvik). After you boot, you will have to install the Magisk Manager app from the playstore if the Magisk.zip didn't already do so automatically. Then enable Magisk Hide and reboot your phone. Root should be hidden now. You will have to regrant root permissions for all of your root apps.

I'm on stock ROM, so I guess I can go into super su and loose root then download magisk and get it that way
Thanks mate, it took forever to find this solution, it worked!
I use SU and it was simple to "unroot" from within the SU# app
1. settings scroll down to the "cleanup" section, select full unroot, accept all the warning messages, the phone will reboot into recovery and then reboot the phone after it finishes. Your phone may cycle through the reboot process a couple of times
2. log back into your phone, then you can log into the Snapchat app.
3. now you can re-root your phone, if you want to.
Cheers.

Unrooting does not work..phone doesnt boot

I want to switch from SuperSU 2.79 to Magisk. I tried the unrooting option in SuperSU but the phone doesnt boot, it stays on the google image. Reflashed SuperSU 2.79 and phone boots without a problem.
Then i booted into botloader and flashed the original stock boot.img from n6f27c factory image, but same result, phone stays at the google image and doesnt boot. Reflasing supersu 2.79 fixes the problem.
What would be the best way to move from supersu to magisk without having to completely wipe phone and flash n6f27c factory file.
Would flashing boot.img and system.img be enough? And then install magisk from twrp to get root again or is there another option that works.

Try using unsu.zip. You can find it in osm0sis' odds and ends thread. Scroll down through the first post.

Magisk bootloop from xposed

I have LLD-L31(C432) and a while ago I went through the process of unlocking bootloader and flashing magisk. I did this without custom recovery as it caused problems but it worked and I had magisk and root fully working. However, I think I tried to install a version of xposed that was incompatible with my os (EMUI 9). This caused bootloop every time I tried to boot into recovery(system with magisk).
I can still use the device but some apps can still see xposed and won't work. I can try to boot into the system with magisk but it loops - maybe because of xposed.
I have seen that you can flash xposed uninstaller, will this wipe data and will it work? Or is there a way to remove it and get magisk back without loss of data.
Alternatively (if this option results in a more stable magisk installation),could I flash twrp to recovery and then flash magisk to my system boot to have magisk permanently? and will this method wipe data?
Edit: I flashed twrp to recovery but when I boot to it, it just loads fastboot with reason bootloader 1 any help?
Thanks

Soft bricked....

So I finally went ahead unlocking the BL & rooted my Mi9Tpro, using the program by Maunofrio.
So far, so good. Installed twrp from within the program, along with some kind of superSU.
I installed some apps needing root, but they complained over an outdated supersu, so
I then installed the superSU by chainfire. First 2.82 wich wouldn't update the binaries.
Then the 2.79 version, that was said to be more bug free.. It didn't want to update the
binaries either, the normal way. So I then chose the other option (to DL by twrp).
Now my phone won't boot past the boot screen. I can start both fastboot and
recovery mode (twrp). Would anyone be kind and tell me how to solve this?
I just don't know how to proceed (so I guess I shouldn't have fiddled at all).
Just flash Magisk for root.
That will work 4sure.

Stuck in Download mode bootloop after updating from v20.x to v21.x

Phone Model no : Samsung Galaxy S6 / SM-G920F
Security patch date: 01.10.2017
Android version: 7.0
Root status: Yes
Hey guys,
I rooted my phone several weeks ago for the first time via odin and everything went fine. I installed TWRP and Magisk and everything worked out.
Today I was trying to update Magisk from v20.x to v21.x with the inapp option, but now im stuck in a bootloop to download mode, screen says "Downloading... do not turn off target".
Even if I turn the phone off with Power + Home + Vol Down its just restarting right away and getting stuck in the same screen again.
Im still able to enter TWRP Recovery, but I dont know what to do to end the download mode problem when trying to start the phone.
I actually dont know/understand much about that stuff, so I dont know which other info I need to provide.
Is there something I could do without going through the whole flash/root process again?
should i try to delete magisk and install it again? if yes, how do i do it?
Help would be appreciated.

I don't know much about your device but if you can enter TWRP, it's not that bad. First what you can try is to download Magisk uninstaller and flash it in TWRP from USB. However, I don't know what can you do to update Magisk safely. Would be best if you can check your device forum or ask the question there

Looked like my device forum is pretty dead, which is why I asked the question here again. Thanks for the fast respone
Its probably not possible to just install a Magisk version again and overwrite the current one, probably need to uninstall first and then install it again?
There is a Magisk Module Uninstaller and a Magisk Uninstaller. Are those different things or just the same?

How to Uninstall Magisk From Android [2 Easiest Method]
Are you facing issues with Magisk? You can uninstall magisk from your phone with these simple and easy steps.
magiskmanager.com
Because the 2nd guide says in the end
Keep in Mind – Whenever you use TWRP as a method to uninstall Magisk, it is imperative to flash the Magisk Module Uninstaller Zip onto your device.
Does this mean I need to do the magisk module one first?
@n00btuber Do not trust those websites. They're in no way official and are just trying to get adc revenue from Magisk's popularity. If you're really unlucky they'll also provide you with malicious zips...
Only download stuff from John's GitHub:
https://github.com/topjohnwu/Magisk
If you need to uninstall Magisk use the uninstall zips from the above linked Github repo, and if you need to uninstall modules (but those will also be removed by the Magisk uninstaller) you can do that directly from TWRP:
https://www.didgeridoohan.com/magisk/Magisk#hn_Uninstalldeletedisable_modules_from_recovery
A lot of times you can just flash another Magisk version over your installed one, but there are times where you do need to uninstall first. Since you have TWRP it can't really hurt to just try flashing whatever Magisk zip you want and it it doesn't work you can just use the uninstaller first.
One other thing to try would be the Canary release, mainly to see if you're affected by any bugs that is present in the current stable release but has been fixed upstream. You'll find the Canary app in the same Github link above.

Ok.
Was trying to use the uninstaller from his GitHub.
Trying to flash it leads to
"Updater process ended with ERROR:1
Error installing Zip file .....
Updating partition details"
So what to do now?
Trying to just flash any Magisk version to overwrite the current one leads to the same result.
I think it says Unsupported/Unknown image format
Your TWRP might be bugged/incompatible. I'd reflash your stock boot image and then patch the file manually (you'll find the instructions for that on GitHub as well).

But TWRP worked fine when installing magisk the first time, I even tried the same zip folder I used to install it back then, but it wont work anymore.

Would a Factory Reset wipe all Magisk stuff and my TWRP Partition as well?
Does anyone know what is going on between Magisk and Google? It seems Google has removed Magisk Manager from the Play Store AGAIN! What's more, I downloaded and installed the apk but when I try to use it to install the latest Magisk the install fails. Tried installing the Magisk zip via TWRP, and while it doesn't show any errors, I still don't have root.
Ok I really need some more help @Didgeridoohan
Meanwhile I tried to reinstall TWRP from within TWRP. There was no error so I think it should have worked, but didnt solve the problem.
As soon as I try to boot the system it directly boots download mode and gets stuck in it. The volume buttons wont work or do anything as they are supposed in download mode.
Im still able to get into TWRP, but I still dont know what to do to stop this crashed download mode that starts over and over again.
When trying to flash the magisk uninstall it states "cannot access /data", when trying to flash a magisk installer it states "unsupported/unknown image format"
I dont care about Magisk right now though, I can root and install magisk again as soon as im able to clear the download mode problem. I was just trying this because trying to update magisk from within magisk manager has caused this download mode problem to appear.
Just tell me please how to fix that or how to factory reset my phone so it is able to boot regular again.
Thank you

Sounds to me like you need to reflash your ROM, not TWRP. According to your OP, you're running Android 7, but it doesn't say if it is stock or a custom ROM.. If it is stock, then use Frija.exe to download the ROM and then flash th AP, BL and HOME_CSC md5 files with Odin. If it is a custom ROM, use TWRP to flash the ROM and gapps. DO NOT try to flash Magisk. Right now there seems to be a problem with Google disabling Magisk. Wait till it is resolved before attempting to get root.
@n00btuber Dirty flashing your ROM is most likely the way to go, just like described above.
But @lewmur, what do you mean by "Google disabling Magisk"? If you're talking about SafetyNet there are ways around that (and it doesn't affect root)...

I not talking about safety net. Look in Play Store for Magisk Manager. It is no longer there. And even if you download and install the apk, it won't install Magisk. Flashing Magisk from TWRP doesn't give root privileges. This just happened yesterday.

That 's my mistake. Play Store would put up a lot of "Magisk Manager" stuff, but I never really tried any of it because flashing Magisk would give me the Manager. But even that "stuff" no longer shows up.
Butt Magisk Manager still won't install Magisk. It will download the zip file, but when it attemps to install it, it get an error saying Unsupported/Unknown image format. If I flash it from TWRP, and then open Magisk Manager, it still says N/A under Installed for Magisk.

That will be an incompatibility between Magisk and your device and has nothing to do with Google (blame your OEM for doing weird stuff instead).
Thanks for the help guys, had to flash the ROM, now its working again.
