I'm attempting to root an HTC eris with one touch root app. I boot into recovery and per the instructions you are supposed to scroll down to flash zip from sd card. However I cannot scroll with any botton on the phone nor can I select it using the touch screen. The track ball does nothing either. Its stuck on "reboot system now" I can press the track ball and select the reboot option but I cannot scroll down flash zip. I have searched and cannot find anything. I'm not familiar with the eris but aqm familiar with rooting, but no buttons on this phone let's me select or move the cursor.
