| Two items come to mind.  One: is this a BulletM2HP or an earlier model?  The prior models do not have enough memory to load BBHN and are not supported.  
 Two: Are you using the bullet "factory" .bin file or the "sysupgrade" .bin file?  For a new Bullet with AirOS on it you need the "factory" .bin file. The "sysupgrade" is for devices that have been previously flashed.  Clint, AE5CA |
