Thanks for all your feedbacks guys! Really appreciate it!
I've tried contacting the RICOH support via their online form but it seems like it's only available for USA and Canada and I'm living outside the State. I'm from Malaysia but I've managed to contact the local support here. Probably will drop by and give it a check on my SC.
I hope it's not the hardware malfunction and it's only the software. I've updated the firmware to the latest once as per on their support page. So hopefully it's one of the bug from the firmware. fingers crossed
I'll give it a try to get into the Mass Storage mode and format it when I get home from work later.
@codetricity, we can charge it using a wall plug? Based on the manual given, I dare not to charge it via wall plug, I afraid I will burn it. Haha..
Once again, thanks all for your help! I've been searching all over the internet for solutions and no one seems to have this issue yet! Probably I'm the "lucky" one! haha
Will keep this threat updated if there's any other issues pop out!
