1 First, we need the installation package of WeChat. Version 6.5.8 is available, but version 6.5. 10 is not available. Change the suffix apk to zip, and then decompress it.

2. Have you seen the folder "R"? Open it, find the folder "n" inside, and then find the picture "ar2.jpg", which is the picture that will be displayed when WeChat starts.

3. Then find a picture with the same resolution (1920x 1080) and rename it "ar2.jpg" to replace the previous one.

4. After successful replacement, recompress the decompressed files and folders.

5. After compressed into a zip file, change the suffix to apk and copy it to the mobile phone. In fact, more than half of it has been completed here. Next, we need to sign this file so that we can install and use it. Signature is a technical term on Android, so you don't need to delve into it, just know how to operate it.

6. It is suggested to sign directly with mobile phone software, because it is more troublesome to install java environment on the computer. Here, a software called "zipsigner" is used to sign.

7. Open it on your mobile phone, click Enter, and find the just completed apk file on your mobile phone. The output is where you want to put the finished file. Just choose a folder you like on your mobile phone. Click "Select File by Signature" and wait for one or two minutes to indicate success. Uninstall the original WeChat on the mobile phone, find the WeChat just made with this software, and just install it.
