1. We usually use tools for Android smartphones. Here we recommend using "flash master". First install a flash master on the computer.
2. After the installation is complete, connect the TCL Mdoda 3 s mobile phone to the computer, and then enable the "master" on the computer. As shown in the figure, click "more tools"
3. To prevent data loss, we can back up the mobile phone data and click more tools = backup master
4. After the data backup is successful, we will download the phone refresh token. After the data is downloaded, we will prepare the ROM and click "browse" to select the downloaded ROM.
5. Now, it may take about 15 minutes for us to quickly access the "one-click flash" flash drive, and then we can use the one-click flash drive of TCL Moda 3 s.
6. At this time, we just need to sit and call the watermelon, and then the flash brush software will automatically complete.
Wait until the "master" prompts us that the flash is successful, and we can remove the data cable connecting the mobile phone to the computer.
