[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?
