Flash it with the 145 bin then flash it with the 352 bin. The 350 and 351 bin will make your box reboot if you had any of these two on last flash with the 145 bin then the 352 bin.
upgrade bin I would say .......BEFORE it's too late, cuz that was happening to me and my pansat 3500 stopped working and never turned on, so get yourself a new good bin http://www.dsstester*com/files.php?cat=14
