Is it possible to push ADB System files without Root?

Question

I'm looking to replace the Generic.kl file on my Samsung. I found a command online to push this file:

adb push Generic.kl /system/usr/keylayout/Generic.kl

But when I tried it says:

"Couldn't create file: Read-only file system"

I assume this is because I'm not a root user. Can I do it some other way? (Fast-boot mode is not supported on Samsung)

Thanks!

@user4463546 that needs root, so the answer is "no" either way. — TheWanderer, Jan 09 '19 at 17:03

No, you need root.

That error isn't a permission denial, though. On Android, the system partition is mounted read-only by default. To make changes, you need to use

mount -o rw,remount /system

That command requires root privileges as well, so it won't run.

Even if system were mounted in read-write mode, you'd just get

Couldn't create file: Permission denied

system is owned by the user root. Permissions inside of system are, at their most lenient, set to 755 or rwxr-xr-x. That means only the root user has permission to write anywhere in system. Since ADB runs under the shell user, you can't write files.

Thank you for this information. Is there any way then to remap a hardware button without root (without an .apk either)? – oo33 Jan 09 '19 at 17:12
I don't think so. – TheWanderer Jan 09 '19 at 17:14
