Star P6 rebooting on boot screen after accidentally installing custom recovery

Hi. My friend accidentally flashed other phones (Xolo - same MTK 6582 Chipset) recovery (CWM_v89_gq3012) on his Star P6. I've tried to install many roms (including stock), but it keeps restarting after boot screen. MTK Droid Tools and SP FLash Tools didn't help,because after turning on phone keeps restarting sooner after android boot screen. Please, help to solve this problem
