Hello, I installed a cleanup app to My Casio C811 Commando that's suppose cleanup and boost an android phone. The problem is once the app finished installing from the Play Store and I selected "Open" my phone now continually resets without being able to log into the cell phone and Android OS. I've tried removing the and re-inserting the battery and then pressing the power button but the same re-setting occurs. If I remove and re-install the battery I'm able to charge the battery without booting the android OS. I know I can do a master reset which I've done in the past. However I recently configured android settings and installed and configured several apps including ones that connect me the cell to my PC and don't really want to lose all my configurations, settings, passwords, usernames, etc. I can't recall if all or only some of the settings and configuration are lost during a master reset. I spent alot of time setting up the android to work with e-mail, various apps, online accounts, etc. The apps I have installed on my PC and that Android that allows my PC to access the android, some allow deletion and uninstallation of apps on the android. MightyText Desktop Notifications Airstream AirDroid I don't believe any will allow me to delete or uninstall an app installed on the cell phone without the cell phone booted and logged into the Android OS. Some rely on an Internet connection both on the Android and PC. I suppose there's noway to remove, delete or uninstall the offending app causing the resetting other than performing a master or factory reset? I wasn't able to get the phone into safe mode. Verizon site: With the device powered on, press and hold the Power button (located on the top-right edge) until the Phone options prompt appears then release. Touch and hold Power off until the Reboot to Safe Mode prompt appears then release. Forum user: if you've messed something and can't boot to normal mode you can try the "safe mode": power off, then hold down Volume Down + Tactical Key + Power and you should boot to "safe mode". Tried both of the above instruction to put the Commando into safe mode. The kept resetting without going into a safe mode. _________ Taking the battery out and re-installing > then holding the volume down and power buttons at the same time. No reset menu is displayed phone boots to it's OS then resets again. I had the phone in it's hard reset menu just a couple days ago, but seem to remember holding three buttons? Volume down + Power + third button? Perhaps not. What am I doing wrong not to be able to place the phone in either OS safe or hard reset modes.? I just had everything installed and configured as I wanted and now one little app messes up the entire phone and makes it unusable.
