Default Installation of karbon a10 stock rom ! Failed ! Help urgent!

I have karbonn a10 which stuck on boot logo after installing chainfire 3d drivers. I can access recovery mode and fastboot. I have drivers for them too. But when i tried 'fastboot update' it says archive doesnot contain android-info.txt and android-product.txt.
Trying adb sideload return 'installation aborted' after hitting 100%.
Within recovery choosing update from sd also says 'installation' aborted.
I have smartphone flash tool too but hitting download and connecting my device without battery and pressing volume button doesn't help, it always searching..., once it has status 'usb'
But the process percentage didnot move.
Now if you have a better plan or step or any advice please tell me...
Please, thanks in advance.
Btw i have downloaded from (from gdrive)
