Blackberry Z10 stl100-1 not charging
I bought my z10 two years ago here in the Philippines. I did not buy it under any telco but I am currently using Globe Telecom here. Last night, it went off because of low battery. I was not able to immediately charge it because I was out and I forgot to carry my powerbank with me. When I got home, I plugged it to the wall socket but to my surprise, it's not charging anymore. What happens every time I plug it, the red LED lights up for solid 15 secs and then the blackberry logo shows up then the empty battery logo shows up and then nothing. Even if I leave for hours, nothing is happening. I tried the trick of plugging it for two hours, then removing the battery for 15 mins then plugging it again but still nothing happened. It has already been a day of not able to use my phone. Can someone help me? Thank you in advance.
PS. I cannot buy a new battery right now because of my busy sched and don't know someone who has a z10 to borrow a battery.
