Default Rooted c6902 using towelroot v1, installed nuts xz1dualrecovery n supersu

After rooting n flashing xz1dualrecovery with the help of pc and then flashing super su 2.00 i am facing strange problems! After a day my phone is not booting in recovery, no vibration or yellow lights during restart! Then after yesterday i saw that its not switching off when i hold power button and then click 'power off' only reboot to safe mode and holding power n volume up is working. Yes i had backed up entire partion via xz1dualrecovery, but after that due to insufficient space i manually delete the backup file from sdcard/clockworkmod/

What do i do? And also tell me please that whether i update 4.4.4 via ota when it come(my phone is rooted, bl locked) ? Thanks in advance...
