Hello all. My TP battery totally drained. I put it on charge now it has they battery box with question mark. I've held down Power+ V Down and home for 30 second and only thing I get it battery box with question mark. I have CM 11 with WEBOS removed using TPToolbox. I tried running Tpdebrick but says unable to initialize. Tried holding Power+voldown+home for 30 seconds. Does not recognize. I've tried different cables also. It eventually says QDL not found. I can't get USB symbol also it keeps coming back to battery symbol. Pls help. Thanks for all the work you put in to this JC and everyone who keeps TP running.
