2. Backup your Data

Backup your data including Photos, Music, Documents or any other type of data that you may have on your phone. You  may copy all the data to your PC by connecting it through a USB cable and then copying all the relevant data to your PC or you may upload all the files to a cloud service like Dropbox, Google Drive. If you need to backup your Messages, Call logs and other such data then there are applications available on the Play Store that will backup anything and everything in your device. This application can directly upload your data onto a cloud service or will make a backup on your device storage. If you choose to store the data on your device make sure to copy it to your PC or somewhere safe. You could try installing CM Backup from the link given below to backup our data.

3. Encrypt your data

Even after factory resetting your device, there are ways to recover some data from your device. To ensure nothing gets left on your device that can be misused, Encrypting your device is the way to go. Encrypting your device makes sure your data cannot be retrieved without using a password that will decrypt the data. To encrypt your device, read the guide linked below.

4. Factory reset

After encrypting your device and backing up all the important data, you need to wipe things off. Factory resetting your device will wipe all the user data off your phone. It will delete all the installed applications keeping System applications only, it will remove all the accounts using which  you have signed in on the device. The device will come to the state as you bought it. The easiest way to do this is to head to Settings>Backup & reset> Factory data reset.

5. Return to Stock ROM/Unroot your Device

If you are using a custom ROM on your device, make sure to install a Stock on it before selling the device. The buyer would like to have the device in the condition as he/she is buying from the store. Also, make sure to install the latest update that is available for the device. This will also make sure that you have unrooted the device. You may search at Droidviews or at the XDA forums meant for your device for the guide to return to Stock state.

6. Lock your Bootloader

If you have a rooted device and are using a custom ROM on your device, chances are you have unlocked your device’s bootloader. Locking your bootloader takes your device a step closer to being stock/ as good as new. While some buyers won’t mind an unlocked bootloader, it is advisable to sell your device as you got it. Steps to do so might differ for each device, but generally, it can be done using the command ‘fastboot oem lock’. The steps to use this command are as follows:

  1. Reboot your phone to Bootloader Mode.
  2. Connect the USB Cable to your computer.
  3. Download and Install Minimal Fastboot and ADB using this guide.
  4. Open Minimal Fastboot and ADB and type the following command to lock your bootloader.
    fastboot oem lock

  1. If you need to delete data from your devices completely, use a MobiKin Android Eraser tool, I think that is helpful.
    You can erase all data without possibility to recover them, but remember to backup them first.
