I haven't tried this myself, but have you tried using ES FILE EXPLORER, like the guide says? This file explorer has the option to enable root, like the guide says, this should work, has I've use ES FILE Exp to edit system files before. Just an idea, but again, haven't tried this myself.

Fx Explorer have allready a root option too.
I dont like the Es Explorer. Its too overload with crap for me.

Other Files like the the build prop i can normaly edit and safe.

You used ES right? NOT PROPER ROOTED, in saving phase ES did deletion of file, thats why your phone not booting anymore

 

[Horayken]

Hello, i have the same problem. made a copy to internal but now i deleted the original and cannot copy the edited one.. i didn't reboot. so the phone still working. any ideas? is rooted with magisk

it seems that the folder is full... 119MB/119MB

As a temporary solution.. I deleted from odm/etc/camera/arcsoft the file that was insidea and get 1.6mb of free space.. that allow me to restore the audio XML file. After that, reboot the phone and still working with the modified volume.. i asume that on the next OTA update all the files will be restored.

I take it this is just for USB C Headphones? Not including Bluetooth?

 

[twe90kid]

Does it just replace the volume config file with a modified version? and does it persist through firmware updates?

 

[Svetoslav2018]

The zip works,It has increased the volume:good::good::good:
You can make another zip,to increase the volume a little more for example value="20"?
Thanks
