I'm coming from a long time being on Windows 7 and regular shell. I'm trying to transition to powershell but cannot find a way to get root permission to android /system via ADB script. This worked formally:
adb shell su -c "mount -o rw,remount /system"
This no longer works. When trying to set chmod or copy systemui.apk to system I get "Read Only file system".
Any help with this would be extremely helpful and I would be grateful. I've googled and googled and nothing seems to work.
