I have bought a rooted Lenovo K3 Note.Yesterday,I accidentally deleted my OS.
I am stuck on boot animation.
I still have Stock recovery but I can't put my phone into USB debug mode in order to flash factory image.

Is it posseble to reinstall OS from service centre And
How much it would cost? plz.. HELP!

Since you have no means of downloading anything to the phone (it's hardware, but you probably deleted all the firmware), you're probably going to need a JTAG service to feed the ROM back into it. Look on eBay for lenovo k3 jtag service. The cost can range from $25 to $150, depending on how greedy and how good the service is. (High price isn't an indicator of experience, nor is it an indicator of greed.)
