Default [Q] Phone stuck at bootlogo, Help!

Ok im new here and I got a question
My Cherry Mobile Candy (CM L102) rooted (z4root) superSU pro 0.8.7
8gb sdcard stock rom and kernel
No recovery (Lost when flashing through mobileuncle tools)

heres my question:
Last night I leaved my phone 17% of battery media player ON
The next mrning I charged it w/o turning it on and when I turn it on it stucked at logo
I entered factory mode and cleared nand flash but nothing happens.
Should I need to adb reboot or flash stock rom? or my phone is dead?
Looking forward for replies
