Tutorial [Guide] Give Android OS Access to HOS_Data Partition

[pcwizard7]

Why do you want this

You can share things like ROMs, thumbnails etc between android and HOS. Plus makes it easy to transfer things with your pc over usb

What you Need

- you will need root access (Magisk)
- Tasker

Method

- enable "Global Namespace" in Magisk Manager.
- open Tasker
- Create an event for "Device Boot" give it a name
- then create a task give it a name

In this task create steps to make it look like this with root access
Shell: su - mm
Shell: mkdir /storage/switch_sd
Shell: chmod 777 /storage/switch_sd
Shell: mount -o bind /dev/block/mmcblk0p1 /storage/switch_sd
Shell: mount -o remount,rw /dev/block/mmcblk0p1 /storage/switch_sd

Enjoy

It should be mounted inside /mnt/storage (/mnt/storage/switch_sd for example), that way normal apps can access it. At least that's the way it works on other devices... Most apps just won't see other mount points outside /mnt/storage.

I feel like I have followed the guide pretty closely but once it tries to run the second shell command (mkdir), I get an error 127.
I have tried both:
mkdir /mnt/storage/switch_sd
mkdir /mnt/storage/switch sd

Same hang up. Any idea what I might be missing?

Thanks for the guide!

FWIW I haven't had to do any of the tasker stuff with Android 10. Once root/magisk is installed every emulator I've tried has been able to navigate to mnt/vendor/factory and read and modify files there.


Now the next task would be to set up symlinks that redirect to HoS folders...

Hmmm, I must have done something wrong further down the line. Magisk says I have root access and I can access root folders but I cannot see mnt/vendor/factory I get as far as mnt/vendor/ but not factory. It doesn't matter if I am in RetroArch or file explorer apps like X-Plore, I cannot get any further.

go get root explorer by speed software install and open app press the menu (3 lines top left) select home scroll down near the bottom
mnt/vendor/factory
done

dont forget let it have root access when asked

does any1 know how to make sure "Global Namespace" is enabled in Magisk Manager?

I read something over at xda not magisk manager but App2SdPro this app can start a Script as su on boot might be worth looking into and its free

First step is su - mm or su -mm?

Shell: mkdir /mnt/storage/switch_sd

This doesn't work for me. "storage" is directly at the root directory in Android 10 so remove "/mnt" from all your commands, then it works.

Edit: Also you have to check the "use root" in each shell step that you create.

Oh. My. GOD! Thanks a ton! I made it work now after doing exactly that!
Not every app seems to be able to read the root access tho, but it's definitely working!

 

[Sayshi]

Sadly I tried this and got the following error (127) like another user did earlier.

Does anyone know how to fix this? Any help would be much appreciated!
I've also checked root access for every step if that helps.

Ah lol I don't even remember writing this guide.
Glad u found it and it helped.

@LeyendaV @lordelan updated the guide with the change.
