The G2 apparently is said to have a pretty failsafe root experience according to T-Mobile, however the people on Team Douche on Cyanogen probably would not disagree. The great people on Team Douche had gone to work on getting cyanogen running on the G2, however they were stopped by a so called feature on the G2 which prevented this root from being successful, in a sense that it boots straight through the device. The folks at Cyanogen however had to run it through the micro sd card, and as it sounds it wasn’t necessarily pretty. This however has not discouraged them, in fact I would say that the folks on Team Douche are now even more determined to crack the G2 than ever.
