Backup your SD Micro memory card to a folder on your computer<br /> 2. On the copy on your computer, delete all &quot;BBThumbs.dat&quot; files in all folders<br /> 3. In your BlackBerry, REFORMAT your SD Micro Memory card.<br /> 4. Copy your memory card contents from your computer back to the SD Micro memory card. </p> <p>If you&#39;ve got internal memory, do the same for your 1 gigabyte of internal device memory. Although that really can&#39;t be reformatted, you should be able to least delete the BBThumbs.dat files in this &#39;memory&#39; too by accessing this in Mass Storage mode. Alternatively, you can temporarily set aside the memory card and use a different SD Micro card and reformat it.</p> <p>I suspect RIM must have improved their filesystem scanner speed, and there&#39;s some stability bug in the filesystem scanner (and the .dat files appear to be some kind of fast thumbnail-index files on the memory card). It has happened before in varions versions of OS 4.6 likely because some optimized-performance thumbnails reader crashes when reading corrupted BBThumbs.dat files. </p> <p>Besides, starting afresh actually improves the thumbnails performance after the initial lengthy scan. Also, your BlackBerry may be slow for a few minutes while the scanner is regenerating the BBThumbs.dat files in the background. But then you&#39;ll have a fast and stable BlackBerry afterwards.</p> <p>Anyway, it seems to stabilize at least one cause of 5.0.0.314 random reboots. </p>
