Timeout while connect to root process #511

Closed o0Mardev closed 3 years ago

o0Mardev commented 3 years ago

Hi, When i'm using root explorer, I am not able to use the app properly. It doesn't let me access to the storage. I'm using android 10 on a custom ROM (Lineage OS 17.1), on the latest version of the app, of course. Maybe it doesn't work because i'm using an older version of magisk 19.3, (unfortunately I can't update it otherwise it will cause bootloop) I tried to disable root for this app and reenabled it, but nothing changes.

Sorry for bad english

I'll need relevant adb logcat output to actually know what is going wrong on your device. But meanwhile, Magisk 19.3 was released June 2019, and this app does require certain newer Magisk features , so there is possibility that the only fix is to update Magisk.

Sorry for the delay, finally got the time to take a look at the log. Some suspicious log entries:

It's not clear what exactly is going wrong on the device (plus that the device seems not very stable, a number of other things are crashing). The timeout for a failed connection to root process is 10 seconds, so I usually look back 10 seconds relative to the timeout stacktrace, but the only thing I could found was a app_process64 linker error, and a SELinux denial, neither provides enough information for what exactly is wrong or how to fix it.

If you are using a Huawei device (saw some Huawei things in the log), which means your custom ROM may be using their kernel image, Huawei kernel is known to break things like this (e.g. They disabled patching SELinux policy from their kernel).

There's also an alternative that may (or may not) work. You can try to install the Magisk module Sui and its dependency Riru, which provides an alternative way to start root processes, and Material Files will try to use that if installed.

Thank you for the help, I’ll leave a positive review on the play store. This is a great app.
