Your OnePlus data may need to recover due to the following situations: accidentally deleted, the data is lost after upgrade the system, data missing after Rooting or ROM flashing，stuck and not responding and so on. These may seem bad, but you can use Android Data Recovery to recover deleted or missing data.
Android Data Recovery is a software that can be used for almost all Android devices, including Samsung, HUAWEI, ZTE, OnePlus, LG, etc.. There are many types of data that can be recovered, such as contacts, text messages, music, videos, photos, etc.. In the process of recovery, your phone data is safe; it will not be viewed and recorded by anyone and any device. In addition, simple steps make it easy for you to restore data.
Steps to Recover Deleted/Lost Data from Your OnePlus Phone
Step 1. Run the software and connect the OnePlus to the computer
Please download and run recovery software on your computer. Next, find and click "Data Recovery" among all the toolkits.
Then, use the USB cable to connect your OnePlus to the computer. At the same time, you also need to enable the USB debugging on your OnePlus.
If your Android os version is 4.2.2 or above, there will be a pop up message on your OnePlus, tap on "OK" to allow USB debugging.
Step 2. Select file types to scan
Then, check the file types you need to restore. As you can see, by default all file types are checked. You can just select the file types that you'd like to recover. And then click "Next" to continue.
Step 3. Scan your OnePlus to find the lost data
Next, you also need to select the scan mode for your data. You can choose the "Standard mode" or "Advanced mode". The standard mode works faster, so I recommend it. When checked you need, click "Start".
Note: There might be a Superuser authorization appearing on your device during the scan. If you get it, click "Allow" to continue. If not, just skip this step.
Step 4. Preview and recover deleted data on OnePlus
When the program scans your OnePlus, the recoverable data are displayed on the window, you can preview them, find and check the files you need to recover, and then click "Recover".
