How to unbrick Karbonn Titanium X

I had Karbonn Titanium X mobile which was rooted by me.
Recently i installed "Hi fonts" app and when i applied new font, it asks to reboot.
But when i click reboot, it stucks at logo about 1 hour.
So i decided to clear data and cache to reboot. I done reset data ( Android recovery <3e>)
But after resetting data also it stuck same at Logo.
I am unable to hard reset also.
Anyone please help me regarding this issue.
Thanks in advance.

Note : I tried SP flash tool also.But it didn't detect my phone. It has Non removable battery option
I tried ADB sideload also. But it showing error " Restarting adbd...... Installation aborted "

Please help me
