I deleted Android OS from my Karbonn device I have a smart phone (Karbonn A50,Android version 2.3.6) which was rooted earlier.

While accessing my files on the memory card, I came to know that I can access the system files and apps:think OS. I've selected all the files and tapped to delete them and got a warning not to delete. On repeated trying, I was able to delete them to some extent and the device got stuck.

Then I removed battery and switched it on. Nothings works. The phone gets stuck on boot logo (karbon smart) and if try to switch it off it doesn't, until I remove the battery.

If connect to PC, it notifies that something has been detected but no device is seen in my computer. I can't access factory reset either. 

Please help me.
