Samsung core gt-i8262 stucking after logo

I did what was asked by xda team...but my phone i s now stucking at black screen...after logo samsung gt-i8262
previously i installed chainfire 3d..and my phone stuck at logo samsung gt-i8262 ...i did hard reset...wiped of cache nothing worked..
I then followed xda forum..used adb to unistall cf3d_uninstall.sh...
Cmd showed me no such file ..existed
and device rebooted...
And now it is bypassing the logo samsung gt-i8262 and stucking at black screen
