Then select the checkbox to enable USB debugging mode under Settings > Developer Options.
  • Make sure the phone has at least 80% battery charge to prevent unexpected device shutdown (due to battery drain) while installing the ROM.
  • Ensure the device is unlocked (not locked to a specific carrier) and rooted with latest ClockworkMod (CWM) Recovery (v6.0.4.5) or install CyanogenMod 10.2 Nightly which includes CWM recovery v6.0.4.5.
  • If the device is stuck at booting or is experiencing boot loop issues, perform Wipe Cache Partition and Wipe Dalvik Cache a few more times before rebooting.
