Probably a really stupid problem. Running Win7 Enterprise (64bit) and cannot get the fastboot.exe to work. The Bionic is in fastboot and plugged in. I double click fastboot and the program appears then closes in a second or so. I tried as administrator and in XP mode with same result. (Same for the adb.exe file) Also tried to root using R3L3AS3DRoot.bat with no luck. Am on 93. Was rooted and updated (but missed the persistent root items)and lost root. I used "MotorolaOneClickRoot_psouza4" from 8/26 to root previously. Thanks.
