Starsat boot problem when antenna attached!

[Arplock]

Hi!
After upgrading my Startsat X5D Ultra, It doesn't boot completely. When it's LED screen shows "ON" ,after a few seconds the receiver restarts automatically and repeats this uncomplished boot again and will repeat it over and over. In this case, both RCU and button on the receiver become inactive. You should just unplug the power or press the power switch on the back.
But, what I found was if I have dettached the antenna cable before powering on the receiver, it boots up !! Although without any signal. Then if I attach the antenna cable when the rec. is on, it will work normally unless I restart it which makes the rec. go through its malfunctioned boot again!
I tried masterbooting the receiver but the problem has remained unchanged.
What's going on? what should I do? please!!!
My guess is : the rec. wasn't powered off when I upgraded it, I might have unplugged it the night before.

It seems the .bin file for x5d that was released on 18th Jun was corrupt! I restored the 12th Jun upgrade and this problem did not occur, however TPS codes are not decrypted by this upgrade. Maybe your x50 also has this problem.
