Features of CWM Recovery:
Here are some of the highlighted features of the CWM Recovery. Sure you might
Choose Zip from SD card:
You can install any zip file from any location on your SD card. The file can be for a ROM, a kernel, an application, a theme or any mod as long as it is in recovery-flashable zip format. This is the most widely used option for installing a ROM that you have downloaded and copied to your SD card. Entering this option will bring up a screen that will allow you to browse your SD card for the zip file and select it for installation.
Toggle Signature Verification:
With this. you can turn the signature verification on and off. When signature verification is on, you will not be able to install any custom ROMs that haven’t been digitally signed to allow installation on the device (most custom ROMs aren’t signed). Switching it off skips the signature verification check and proceeds with the installation.
Install zip from Sideload:
This option puts the phone into the new ADB sideload mode, allowing you to install zip files from your computer using the ADB sideload command introduced in Android 4.1 Jelly Bean
Apply / SD card/ update.zip
With this option you can install any official or unofficial update, ROM, kernel etc. that is in a zip format installable from recovery, as long as the file is named update.zip and it has been placed on the root of your SD card
Wipe data or Factory Reset
This allows you to wipe all user data on the device as well as cache. Doing this will leave your phone in the state it was in when you bought it or when any custom ROM was first installed. It will also wipe any sd-ext partition that you might have set up. Selecting pretty much any operation in CWM, including this one, will bring up a confirmation prompt that can save you from a lot of potential trouble in case you accidentally select the wrong operation.
Wipe Cache Partition
This can help you wipe the cache partition of the device to clear all the data accumulated in their overuse. This is often used before installing a new ROM, app, kernel or any similar mod via recovery.
Backup and Restore
Undoubtedly one of the most important features provided by a custom recovery, the backup and restore feature, also known as a Nandroid backup, allows you to take a snapshot of your phone’s entire internal memory including all partitions, and save it on the SD card.
With this option being similar to the Restore option but once a backup has been selected to be restored, this option allows you to choose the parts of it to restore. You can choose to restore the boot, system, data, cache and sd-ext partitions.
Free Unused Backup Data
This way you can reclaim space on your SD card by freeing up any redundant backup data that isn’t required.
Choose Default Backup Format
You are allowed to choose between ‘tar’ and ‘dup’ for the backup format. I would advise you to leave this one as it is unless you know and you are sure you want to change it.

How to Use CWM Recovery?
You can directly and much conveniently reboot from recovery right back into recovery. This is a useful option for certain back-to-back installations that require the device to at least boot once between them.
Wipe Dalvik Cache
You can wipe the cache for the Dalvik virtual machine, which is a custom built java machine for Android. This is required before most ROM installations and at other occasions too, for fixing some problems.
Wipe Battery Statistics
Wipes the saved battery usage statistics and effectively recalibrates the battery. Useful in various scenarios when Android isn’t showing correct battery levels. This option is present in many versions of CWM recovery.
In case of errors, this feature can be used to save a log of recent CWM recovery operations on the SD card that you can later report from Android using ROM Manager.
Lets you tap any of the hardware keys to see if they are properly functioning and to see their key codes.
Shows you a log of your recent recovery operations.
You can fix the file permissions for the internal memory partitions back to default. This is very useful as a fix for several errors and Force-Closes that start appearing after you or an application you installed and provided root access end up messing up the permissions of important files.
Partition SD Card
With this option, you can partition your SD card properly for use with ROMs that support data2ext (a very handy hack for low internal memory devices that enables an or SD-ext partition on the SD card to be used as the internal user data storage that is, as the or data partition).
Once you have selected this option, you will be given options to choose the sizes for the or SD-ext partition as well as an optional or swap partition on the SD card, and will then automatically format it for you, leaving the remaining space for normal SD card usage. This option will wipe all data from your SD card so use it with caution!
What is Android Recovery?
All the Android devices including Oppo A7x, ship with a recovery console that is basically a partition on the internal memory of the device and can be booted into. The stock recovery of almost all the android devices provides a few basic yet handy options that allow you to factory reset your device, clear its cache partition, and recover its operating system using an official ROM in zip format, but that’s all you can do with it. That’s where a custom recovery comes in handy.
A custom Android recovery basically replaces the stock recovery with one that lets you do all you can do with the stock recovery, plus a package of more options to give you a lot more control on your device. With a custom recovery, you can install official and also unofficial ROMs as well as other updates including hacks, themes, kernels etc. using zip files, wipe not just user data but pretty much every standard partition on your device, mount the storage card for USB mass storage access without leaving recovery, partition your SD card, wipe Dalvik cache and battery stats, fix permissions, perform, manage and restore backups, and so on.
