You are also shown your available storage space, and you can calculate if it’s enough for the backup, based on the sum of the individual partition sizes, that are shown with each partition.
This section lets you restore your phone to the state of any previously taken backup. Simply select the backup that you want to restore, optionally choose the specific partitions that you want to restore, and swipe the slider to begin the restore process.
Do remember that restoring a backup will essentially wipe the current state of your phone, meaning any changes made after that backup will be lost. However, your internal or SD card storage will remain untouched, and any files that you may have added there after the last backup will still be there.
Most casual users will never really need this section, but for power users, this can be immensely useful. Here, you can mount or unmount several key partitions of your device, in order to access them over ADB (or certain areas of the recovery, as we’ll see later.) You can also see the amount of free internal storage available on your device here.
TWRP lets you tweak a few recovery-specific settings, such as toggling signature verification for the zip files you flash, using the rm -rf command for wiping instead of the format command, wherever applicable, skipping MD5 generation during backup, enabling MD5 verification of backup files, using military-style time for the clock display, and a simulation mode in which you can test out recovery operations without actually performing them, which is super-useful for those creating custom TWRP themes, in testing them out to ensure they apply properly to all areas of the recovery.
The Time Zone option lets you specify your own time zone for the time display in recovery mode, by choosing it from a list of all global time zones, and optionally specifying any offset if required.
To keep things secure, TWRP also comes with a lock screen that activates automatically after a predefined screen timeout period, and can be unlocked with a swipe similar to the unlock gesture on the iPhone, as you can see in the screenshot above. This option can be toggled from the Screen section.
In the Advanced section, you’ll find some further features that many users might not require. You can copy the recovery’s log to SD card for accessing it later, which can be useful for debugging purposes. You can also fix file permissions, which can help if things aren’t working properly due to improperly set permissions for important files. There’s also a Reload Theme option that is useful for those developing a custom theme for TWRP.
The ADB Sideload mode is also accessible from here, which essentially allows you to put your phone into a mode where files can be flashed to it from a computer using the ADB sideload command. This mode shouldn’t generally be required by anyone who doesn’t already know how it works, and those unfamiliar with it don’t really need to worry about it. For those who are going to use it, the Wipe Cache and Wipe Dalvik Cache options can come handy to ensure that both these cache partitions are wiped after the ADB sideloading process completes.
There are two more options here – Terminal Command and File Manager. These (especially the File Manager) deserve a section of their own, so let’s now take a look at them.
Not many custom recoveries come with a built-in file manager, but TWRP has taken things one step further by adding one to the mix. Once you launch it from the Advanced menu, you are shown the file or folder selection screen. Simply navigate to the file or folder you want to manage, and hit the ‘Select’ button. For conveniently locating the required file or folder, you can use the sorting options.
Once a file or folder has been selected, you can then copy or move it to another location, set its permissions to rw-r—r– (755) by using the ‘chmod 755’ button, or to any other permissions you want by using the ‘chmod’ button, delete the item, or rename it. These options can come incredibly handy when attempting to fix things from recovery in case of any issues that have made the phone inaccessible in normal Android mode. However, use these only when you are sure of what you are doing, and don’t mess around with any files that you don’t know much about, or else you might end up harming your OS.
The Terminal Command mode found in the Advanced menu lets you run a batch file that contains Terminal commands that you want to execute. These files usually have a .sh extension, and if you are unsure about this mode, just let it be, as you won’t exactly need it in that case. For those advanced users who do need to run such a file, TWRP offers the same file selection interface in this section that’s featured in the other parts of the recovery, as we’ve seen above. Simply select the file and you’ll be able to run it right from recovery.
This menu provides you with handy options of rebooting your device directly into specific modes right from recovery. The options available include System (normal Android mode), Recovery, and Bootloader (fastboot mode). In addition, you can also directly power your device off from here.

Overall, TWRP has almost replaced ClockworkMod Recovery because TWRP provides the most impressive user interface we’ve seen in recovery mode, making it a very easy-to-navigate GUI – a major jump from the traditional menu-based boring and complicated recovery interface found in most other recoveries including ClockworkMod. So, i’d recommend TWRP Recovery instead of ClockworkMod as i also use TWRP on my Nexus 4.
