Problem after upgrading a new firmware my TVBOX always goes to recovery !

[google99]

Hello,

I have obtain a firmware for my MK68 (RKM) for the official site, and now i always go to the recovery !
This is like the system is not install !
I have installed "TWRP" and when i click REBOOT SYSTEM it restart my TVBOX and still goes to the recovery !
I did try to do the following but same problem :
--> Tools : AndroidTools v2.01 did ERASEFLASH and also LOWLEVEL FORMAT and reinstall the rom : KO
--> Tools : Rockchips Batch tools 1.8 : RESTORE : KO

Is there any apps on pc to restart my box to SYSTEM in recovery (REBOOT SYSTEM) does not work or any other tips ?
now my box always goes in recovery and not able to start Lollipop

Thank you all
