Android OS SD card reflash or self update
<p>I have an interesting question to share with all of you.</p>

<p>I have a working PandaBoard running Android OS ICS 4.0.4. Normally I will use fastboot to update or reflash the SD card but this time I would like to do it differently. I would like it to automatically update the Android OS if USB pendrive is plug-in after it boots up.</p>

<p>I have seen a number of tablet devices do the same thing. Simply place the image file into the USB pendrive then plug into the tablet before it boots up. Once the tablet power on, it will scan for USB pendrive and update from there.</p>

<p>Does anyone know how can this be done? or at least where this information I can get from?</p>

<p>Many thanks.</p>

<p>Yong</p>
