I'm not sure what I've done to my phone! I pulled it from my pocket this afternoon and I found I wasn't able to operate my Samsung Galaxy Rush. Instead of my lock screen, my screen is mostly black with an android avatar in the center, beneath it reads: Downloading... Do not turn off target. In the top-left screen it reads: [ODIN3 FACTORY] PRODUCT: SPH-M830 VERSION: M830VPBMD5 CUSTOM BINARY DOWNLOAD: NO CURRENT BINARY: SAMSUNG OFFICIAL SYSTEM STATUS: CUSTOM The next dozen lines or so down the screen read: usb_read() transaction failed odin: oops! I believe these reflect my attempts to fix the issue myself. Finally, the bottom line reads SECURE FAIL : [0x81]pit I don't know what this means or how to troubleshoot the issue, its never happened before but I'm almost positive that it isn't good. Even after reading several forums and supposed explanations I've made little progress to resolve it. Can somebody please help?!
