<div class="">There are 3 I can find documented internally.</div>
<div class="">1. Soft Reset (documented publicly)</div>
<div class="">2. Hard Reset (see below)</div>
<div class="">3. Hard Reset but keep network settings (Terry’s)</div>
<div class=""><br class="">
</div>
<div class="">The hard reset is:</div>
<div class="">3491672850*# - the “nuke it from orbit” option which is a total format the flash, hard reset but does not preserve the network.</div>
<div class=""><br class="">
</div>
<div class="">Prior to version 8.3.3 only the first 2 existed, but number 2 unintentionally kept the network preferences, acting like number 3 does today (see CSCsi60439).</div>
