[Q] tried to install custom rom on a35 topic

I tried jelly blend v1.0 on my a35 Micromax bolt, i installed base ROM finely, but when i tried to install main ROM, then system hang up, i pull off the battery and again insert it, and again tried installation. Then further system hang up, then i further pull of the battery and inserted that, now i lost my fastboot mode and cwm recovery (previously installed recovery.img using fastboot mode) . When ever i put battery in my phone, it is automatically showing BOLT logo even i am not starting it manualy by pressing power button. I tried spreadtrum tool to flash STOCK ROM of A35 Bolt, but pc is not detecting my phone??? please help me to get back to my fastboot mode and recovery mode:(:(:(
