    2. Re-insert the battery (not the memory card).
    3. Turn on the device. If the device successfully starts, re-insert the memory card and turn on the device. If it fails with the memory card inserted again, the memory card is causing the problem. Then:

    4. Wipe the cache partition to clear system memory. For steps, see how to guides > Reset.

      Note: If the phone prompts to restore saved settings from before the reset, decline it. The issue may have been related to a setting.
    9. The phone may take some time to turn on. If the device successfully starts:
      • SeeMemory and storage management: Android, and follow the steps regularly.
