How to: Mount System RW in Android
Google's Android smartphone operating system uses Linux, UNIX and Java as base. This means that advanced users can utilize a terminal interface, giving commands and instructions to Android via a command line instead of a graphical interface. Root-enabled users can set the System folder to a read/write state, just like a command line on a Linux system. Using a command line is an advanced technique - novice users should avoid terminal interfaces.
Things You'll Need
- Rooted Android phone
Turn on your phone and unlock the screen. Press the "Home" button. Tap the application drawer. Tap "Market."
Press the "Search" button. Enter "Terminal" and tap "Go." Tap "Android Terminal Emulator." Tap "Free," and then "OK." Wait for the app to download and install.
Press the "Home" button. Tap the application drawer. Tap "Terminal Emulator."
Hold down the "Menu" button if you don't see the Android keyboard. Type "su" and tap "Enter." If your Superuser app appears, tap "Allow."
Type the following text inside the quotation marks exactly: "mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system". Tap "Enter." Your System folder is now set to read/write mode.
Tips & Warnings
- Some root-enabled file explorers use a read/write switch built into the graphical user interface. These are typically easier for inexperienced users to operate. For a popular free root-enabled file explorer, search for "ES File Explorer" in the Android Market.
