I got a cracked Qin F21 Pro , and when removing a built in Chinese weather app with adb I seem to have bricked the phone. The power on/off animations work, as does the confirmation prompt before powering off. After powering on, the screen goes black and I get a pop up that system UI has stopped responding, with the options for closing the app or viewing app info. I’ve tried resetting the phone but when I got to the screen with the android bot on the floor with a red triangle and exclamation point from which I was supposed to hold the volume buttons I was unable to continue due to the lack thereof. I found a thread on XDA developers that mentioned this but had a whole process with reflashing the phone, something I’m not sure I understand how to do. Any ideas?

                    How could I remove annoying toasts from an app

                      Ak123 SUre. To show a toast in smali, it uses something like
                      invoke-virtual {v0}, Landroid/widget/Toast;->show()V. (of course the register can be different.) So look in smali for Landroid/widget/Toast;->show(), and remove the line invoking it. This will always work unless you are dealing with an obfuscated APK, in which case you need to either: deobfuscate it, or make a Java class that blocks all toasts from showing and invoke it in every single activity onCreate onResume and maybe onPuase (I might be missing something).
