I recently upgraded a Motorola Defy to use CyanogenMod 7.2 as Motorola was not going to upgrade the phone from Froyo to Gingerbread. While the upgrade went reasonably smoothly and the phone is working well albeit with a few quirks, there was a major issue that I ran into recently. The phone loses its signal when it's roaming. Fixing this basically involves installing an (unsigned) app named Baseband Switcher, and setting the correct baseband for the phone.
Today, I'm trying to root one of my Android phones in order to install Cyanogen Mod 7.2! First issue: while attempting to root the phone (a Motorola Defy running Android 2.2.2 Froyo), I ran into the following error message while following this guide:
C:\Users\foo>adb push rageagainstthecage-arm5.bin /data/local/tmp/
cannot stat 'rageagainstthecage-arm5.bin': No such file or directory
