Need AHDS2-1011 Firmware

First of all; I am totally a newbie.

I had purchased Solid AHDS2-1011 last year.
I haven't used it for satellite reception until last month.
It used as Android TV Box for months.
But, when I tried to use as a satellite receiver, I found that many errors in its firmware.

1. frequent restarts when viewing satellite channels
   
2. cannot manually add frequency
   
3. by a blind scan it will add satellites and tps but showing wrong frequency
   
4. some times it seems that all saved satellites and tps had deleted
   
5. if under above condition my stb will not accept default rest code to do a factory reset
   
6. also i couldn't add new satellites (not saving)
   

Now my STB is in above condition.

I hope, If flashed firmware again, all errors will be corrected.
Please help me on this.
