MK908ii stability problem

[Boocy]

Hello,
I am having really big problems with my mk908ii tv box that I bought from geekbuying.com

The problem is that the device is very often restarting and applications are crushing all the time. I have tried so far changing power supply of 2 amps, I tried reinstalling many ROMs;

* Stock ROM 4.2.2 (okay this sucks)
* Finless 1.5a (this one worked the best, but still restarting a lot and apps crashing)
* KitKat Finless 2.0 beta (worse then 1.5a in terms of stability)
* HFW 2.0.2 and 2.0.3 (could not start booting at all)
* 4.4 kitkat beta 1 (very bad)

I tried editing 1.5a vsync finless kernel by lowering frequency a little bit/boosting voltage, in my opinion that should provide stability.. but it didnt really..

What is optimal input voltage for this device besides 2 amps of current?

Does anyone have any solution?

Regards.

Have you change your power supply?
Her stock power supply is often faulty
I'm suggest you to change it for a good 2.5A or 3A, it's work well for mine.
