[Q] Some other functions of my device not working.

Hi there. I need help for my device. After I rooted my Samsung galaxy core I8262 i'v planned on installing the CWM Recovery. But before that, I tried to back up my device using the TITANIUM Backup. While the backup procedure is on the process my phone shuts down (because the battery is low i guess). After then, when i turned on my phone, the boot process stops only at the SAMSUNG logo. But after a couple of restarts (maybe 10 i guess) my phones passes the boot process of the SAMSUNG logo. Now while i'm using my device I've found out some other malfunctions like:

1) I can't detect and bluetooth devices even other devices tried to detect me but its undescoverable.
2) I can connect to a hotspot device, but i cant access the Internet even if it has a connection.

So far those where the problems that i had encountered yet after the backup problem occurs. What should I do in this kind problem? Should i upgrade my firmware?

Thanks

Download the stock firmware from the site SamMobile, then turn off your phone and press Power + Volume ↓ + Home and vibrates when the phone leaves the power and press volume ↑. Then connect your phone to the PC, open odin, click pda and select the file . md5 of the stock rom you downloaded and click start.
