Ok, I updated to Magisk v15 in my Huawei P10 (Nougat), and it not only /data was formatted and encrypted without warning on next reboot. It turns that even if I format /data again from TWRP to disable that freaking useless encryption, verify the partition is clean (and decrypted), manually install Magisk again in the shiny empty /data, verify that no encryption was triggered., Magisk Manager has both "Preserve force encyption" and "Preserve AVB 2.0/dm-verity" un-checked and guess what? A couple of reboots later I found /data is encrypted again, without warning, notification or anything....

Is there a way for Magisk v15 to stop triggering encryption and ruining my data or I will need to stick with v14? Versions 13 and 14 it respected my will. I really do not want /data encrypted. It generate lots of problems for me (ie: /data encryption is not handled correctly by TWRP with these Huawei models), spite the unneeded/unwanted IO performance hit...

If you need logs, I could generate them.
[Magisk] Alucard:
Yes exactly that.

[Magisk] mobileman88:
Ouch.. that happened to me before last year. You need to wait for the encryption to complete and if your phone has a lot of data, it can well take 1 hour or so in the blank screen. My mistake was to reboot it after 30mins and ended up with that screen. Had to format all the partitions and restart from scratch.
[Magisk] Alucard:
Mine says to put the password in,i put it and then it says pass was correct but data is corrupt,so what to do,oflashed clean from the start but still the same.

Magisk 15.0 not installing

Android is OPPO spectrum os (AOSP based) marshmallow 6.0.1. No custom recovery for my phone so I patch boot.img and flash with fastboot. 14.0 works flawlessly however 15.0 does not - I flash and reboot and go into Magisk Manager and Magisk is not installed. Tried rebooting again - definitely not working. Here is the boot.img patch log:

[Magisk] sporifolous:
Just installed an update to Magisk from a notification prompt, and now my Galaxy S7 won't boot. I'm stuck on the blinking Samsung logo. Pretty disappointed that my phone is non-functional after just installing a routine update. Can Magisk be trusted anymore? I would have just ignored the notification, but that damn thing keeps popping up constantly until I update.

I'm seriously disappointed and frustrated right now. Might have lost some photos of my son's first Christmas too.

I know I'll never be updating Magisk again without doing a full backup first.
[Magisk] jfracine:

[Magisk] jhill110:
Same here on my galaxy tab s2 nougat. No matter what I try (Flash untouched boot img etc) 15.0 bootloops me. Tried from MM, tried flashing in twrp no good. I went back to 14.0 on my Tab s2.

No problem with my HTC U11.

Always have a lifesaving recent backup of my system so it's really nothing more than a hassle. Hope this gets figured out.

Is there any easy way to upgrade Android and keep Magisk root?

For SuperSU I just used FlashFire and that automatically rooted the device. However, I'm not sure that method will work with Magisk.

Why you are doing that,

I can't disable it, when restarting the magisk manager it is on by default.

Any solution for that.

For those having issues with Adaway it is a known issue and the Adaway developer needs to fix it [MENTION=4470081]topjohnwu[/MENTION] knows about it and apparently it is not fixable on his end, but there is a workaround, you need 2 things

1. UID of the app (Unique ID) each app on your phone gets one once installed - Simple System Monitor free app recommended to get this navigate to Active Process after opening adawy even if it is not working

[IMG="Simple System Monitor"]https://xdaforums.com/attachment.php?attachmentid=4370396&stc=1&d=1514280426[/IMG]

2. you need to manually add the app to MagiskSU.db located at data/adb/magisk.db - policies aSQLiteManager recommended for this

Android 5.1.1

Magisk 15.0

Just installed Magisk 14.6 yesterday in the evening to do a fresh install of Magisk 15.0. Resulted in a lost IMEI, and thus no network lock of the SIM after installation of the latest Magisk Manager and Magisk. Found out cause the Pad asked for an SIM network unlock key after reboot, while it has always been a SIM unlocked WorldWide device.

Will further investigate and check on it tomorrow when I got some time. Hope I'll be able to restore IMEI and get a network lock again. Will catch some logs.

[Magisk] Floodland:
Seems like messing with /data has consequences. I still don't understand the partition format and forced encryption triggered in Huawei devices, when devices were perfectly healthy, and in my case running without any kind of encryption before. V14.0 did not produce the issue, even when it does write the same partition.

Are you going to pull v15? It would be prudent to do it...
[Magisk] Alucard:
Yes they should.
[Magisk] nature boy:
Really wish Magisk Manager would let me flash an older version, it keeps going online to get the latest (and bricking) version.

Some of us have don't have TWRP, because our devices are either new or no developer support (like tablets).

Nextbook Ares 8A, Intel x86, Android 6.0.1:

I used unsu to remove supersu, reflashed my original boot.img in twrp, then flashed Magisk 15. On reboot it freezes on the splash screen, before the boot animation. I let it go for some time and it never booted. I backed up the Magisk patched boot.img in twrp and zipped it along with the original boot.img. Here is a link to it:

https://drive.google.com/open?id=14mUo63H1xZ-j8XVoOqfcfnGF8-s5a7_v

I tried multiple times, including a reinstall of the rom from original twrp backup one, Since Nextbook has never released a rom upload for it.

Could you please take a look at it and advise.

I used Magisk uninstaller, reflashed the original boot.img and supersu.zip and it boots once again.

A day before I tried Kantjer unofficial Magisk-v14.6-171222.zip and had the same result.

Same here, though I can get it to work by enabling force encryption. Yet, this leads to a SafetyNet fail. I've tried renaming the Magisk 14 zip to the Magisk 15 zip and disabling my internet connections, but no result. I also can't find a way to set a legacy update channel. I guess using TWRP is the only way.
