Sorry the name is missleading, it's not restoring the trucha bug. But even if it was, it wouldn't help you, as it only touches IOS15 and IOS36, but you need the system menu IOS and/or ALL game IOS with trucha bug/ignoring signatures. After using TBR you have an IOS that allows you to install the IOS you need for what you want, but you need the right app to do that.
