cant copy files on system/lib

[Android Question]

ok, im trying to run an emulator that runs .jar (java games and stuff). but to fully install the app i found i need copy a file in my system/lib folder. after some research i found out that the systems folder is a read-only and to change that i had to use a terminal emulator. and so now im using it punching in "mount -o remount,rw /system" but all i get is operation not pemitted.
so now i look this problem up again and aparently i need to activate "su" or super user........

how do i do that

Hi

You have to have root access (without it supersu or superuser does nothing) to your phone to do what you are trying to do. Start by finding out how to root your phone (phones all have different methods)

Ok i just googled root access for my phone and im finding stuff on how to how to root my phone. Is this the same thing?

 

[repgam]

sorry about my last message i read it wrong lol i have stuff that rooted my phone but i still having the same issues and error messages in the terminal emulator.

Hi

I'm not sure whether you have a rooted phone or not. There is an app called rootchecker that will tell you. I suspect it is not rooted - you would know if you had been through the process. Just installing supersu or superuser does not root your phone.

I actually do have root checker And it says i do have root access

Hi again

Have you installed busybox?
https://play.google.com/store/apps/details?id=stericson.busybox

Try running the commands in that

Hi

You you may need && instead of a comma. See

Execute combine multiple linux commands in one line - Stack Overflow

ok now when i munch it in with && instead of a comma it just says

usage: mount [-r] [-w] [-o options] [-t] device directory

and the file still dosent copy to system/lib

 

[girolez]

Hi

Im not sure what you are trying to do. Mount locates a whole file system. Remount is not a valid command afaik.

To copy a file to a folder normally cd to its location and use cp command

See Unix Copy Command Examples [ cp command ]

All i want to do is to make the system folder from read-only to read-write

 

[girolez]

Hmm

I think all you need to do is install a root capable browser such as ES file explorer and give it root permissions. You can then do anything you like in all folders, but be careful!

Ok i got the app and gave it root permission and it still wont paste on system/lib

 

[repgam]

Nvm i got it just needed to fiddle with the settings lol thank god its all over lol

Glad it's sorted!
