Hi, I bought an used MyTouch phone, and it is OS 2.1. I formatted my sdcard because I think I don't need things inside sdcard. After that, I can't reboot my phone anymore. I used "adb logcat" to see what's happening there. I saw a whole bunch of "can't open dex cache /data/dalvik-cache/.... file not found" errors. I guess it needs something inside the previous sdcard to boot it up. What can I do now? I cann't boot my phone, it is stuck/freeze at green "MyTouch 3G" screen.
