Please, firmware for mp4 ( vx858 ? ) 16gb samsung memory, 2.8", touch, camera
 

I have a mistake while updating firmware for my mp4, and i forgot to backup firmware. So, you knew, it stopped working :(
My mp4 ( vx858, vx858le, or vx858(le) clone, sr i don't know ) : 2.8", 16gb memory (2x Samsung 849 K9HCG08U1M PCB0,i think ) Rockchip RK2608A b97637 0841, with 1.3M camera.
With :
"Mini MP4 Player" startup screen
"Goodbye" shutdown screen
So sorry, I have little information about it, I bought it long time ago, so there are scratches on its surface, I couldn't read what's written on it.
If you know or you have this firmware, please tell me or sent to my mail : restivehorse1806@yahoo.com
Thanks so much, and sr about my bad E.
