Root Explorer and ES can do some of these things. I use ES to manage files sometimes but I'm not really sure about mounting and re-mounting the system. Script Manager for sure can do all this. Another option is to use terminal, either on a computer or an app on the phone. Here's a link to a guide.
Hope this solves your problem. Even if it doesn't these are still good things to know.
Ok so these are the steps I took exactly:
*Opened the Script Manager and gave it superuser permissions
* Selected the menu button and selected advanced
*selected the option that says "Mount/system as FW"
*then I went into Device>System>usr>keylayout>sec_keypad.kl in Script Manager
*Then I selected "text." But when I did that a screen popped up that read:
"you only have read permission with this file. do you want to create a local copy and edit it or open file directly"
*Then I selected "create copy" and when I did that a small Notification popped up that read:
"File RW permission denied, using a copy"
I don't know if you are getting the same notifications or screen popups as well but from what Im understand is that these popups are not good and its basically telling me that something went wrong during the mounting process. Any suggestion??
P.S. I also have a video of the steps if you would like to see
