Once you do so, you will be in a position to try out a plentitude of mods. Some of the most popular ones include Magisk Module, Xposed Framework, Substratum Themes, Viper4Android, among others. However, there are two sides to this. While they tend to add new features, they could prove to be risky as well, if not done correctly. When that happens, your device might end up in a bootloop, softbrick, or hard-bricked state. For the first two, you could easily fix it by flashing the stock firmware via Fastboot Commands. However, it is the hard-bricked state that is a cause of concern for many users. Fortunately, OnePlus devices come with a Qualcomm chipset and hence have an Emergency Download Tool. Making use of the same, we will show you the steps to unbrick the T-Mobile OnePlus 7 Pro device via the MSM Download Tool.
