I've had a few problems with my phone before but it had always solved itself within a day but just a couple of days ago, my phone has been stuck on either the phone's battery logo or the device logo. When I tried to wipe my cache via the recovery menu but it keeps on redirecting me to Odin Mode?? I've tried more than enough to remove my battery, put it back in then restart or taking out my sim card & SD card then restart or just letting it charge but it just won't boot up. It's never happened before but it just might be that my phone is really old since it's a Galaxy Note 2 and I've been using it for 4 years now. I don't want to fully factort reset it since I have really important things in the device, any ideas?
