Hi over here. Greetings and good New Year's Eve wishes from Argentina.
It turns up that someone has bothered to make a tutorial video on YouTube of the process and, as he mentioned the source, that's how I found this thread.
I've performed the steps and while it seems to have worked (the Root Checker app says the device has root access and the FontChanger app, which didn't work before the procedure, now works), some other apps such Substratum or better font-changing apps like iFont or HiFont, doesn't work. And yes: I did installed the Magisk module for each of them.
Is this due to the root is not at system partitions level? Or am I doing something wrong?
Great post I've tried it and it works.
The only problem I had is that you can't use the latest version of Magisk Manager you
need to use the 7.0.0 version if not Magisk manager won't open after running the suboot.sh script.
I was wondering if with this we may be able to get full root and also turn the notch on and
off on devices that don't have the Full Bezel option in Display Settings or Developer Options.
I tried it as well and it works. Thanks for letting us know I've been checking these forums every week waiting for something like this. I also used Magisk 7.0.0 inside the 18.1 Magisk zip. Latest version didn't work.
I got OTA update today while this thing was running so no OTA issues.
Just 2 warnings:
1) Don't write even a single byte to system partition or boot partition.
2) Don't expect Netflix etc to work since it breaks CTS profile and basic integrity. Banking apps etc will whine for rightful reasons too.
