I'm getting nonstop "Unfortunately ... has stopped" messages including "Trebuchet has stopped". I have ROM'ed my phone in the past (to CyanogenMod). Until recently CyanogenMod was working great. I haven't made any changes to the phone lately, but it was started to act buggy, I figured I would soon have to ROM it again, but now I'm stuck. How to I get out of this jam? I'm not able to boot to recovery. I can't do the Power-button+Volume-down thing. And I'm not able to do the long-press-power-button thing. It only gives me the options to reboot or to shut down. Update 7/10/13: By removing the battery, putting it back, and doing "Volume-Down-Home-Power" I was able to read "Download Mode". Can I use that to get out of this mess?
