v13.3, Huawei P10 Lite: MagiskHide suddenly stops working for non-obvious reason

[vroad]

My device is Huawei P10 Lite (WAS-LX2J) and I'm using stock kernel/ROM. Build number is WAS-LX2JC635B106.

MagiskHide works only for a short amount of time after reset. Then it suddenly stops working. I don't know what caused this issue. It survivied reboot at least once. Restarting the device/magiskhide doesn't fix the problem. (No "Starting MagiskHide" in logs) How can I make this work reliably? What is preventing magiskhide from starting?

Here is the log when MagiskHide works.

Here is the log after MagiskHide has stopped working and I rebooted the device. MagiskHide won't start no matter what I do.

I've also tried erasing /data/magisk.img and didn't work either.

MagiskHide starts working again if I uninstall Magisk and re-install it in recovery.

Thanks

This time MagiskHide starts, but it doesn't seem to do its job. Re-installing Magisk doesn't fix the problem either.

• It doesn't relink /sbin
• proc_monitor does not log anything when I add/launch processes from which I want to hide root.

I forgot to mention that I updated Magisk to v13.6 beta and updated firmware to B170.

MagiskHide stopped working again when I was using v13.5 on B170, and re-installing worked several times, but doesn't work now.

Can you check if logcat is logging for you? I just noticed that logcat stopped all logging, and that caused hide to fail. It seems that either using the secret Huawei service menu to enable LOG entries (background settings - LOG - check all 3 entries) or enable USB debugging (you need to restart hide after this) fixes it temporarily. I just want to know if it's just my Mate 9 that's being a jerk or if it's Huaweis fault :P It was working fine for a week or so, then it started not working... And I just now realized logcat stopped logging stuff since yesterday, I was researching a different issue not related to Magisk at all.

Sorry for posting again, could you try flashing the Huawei prop fix in here https://drive.google.com/open?id=0B2D9GdWntw69emFOTEtxRWlRc0E (thanks to mankindtw @xda). It works fine for me now. Just had to go to service menu and enable logging again, after that it stayed enabled even after rebooting a few times.

Thanks, I'd like to try that fix later.

I've found a user reporting the same MagiskHide issue on XDA (Enabling USB debug and restarting MagiskHide fixes the issue). And doing so also fixes the issue on my P10 Lite as well. So I guess that the issue occurs on many Huawei devices.

Hey guys. This is obviously not a place to ask instructions, but I couldn't find them anywhere else so sorry for that. I was wondering can someone give me instructions how to install Magisk on P10 Lite? Again, sorry for posting this here.
