I know that threads named like this are constantly being added, but I think my problem is a little bit different.
My phone started to cry that it has 13%, ok, I'm plugging cable and... nothing. It was still on so it is other kind of problem
than every one else I went for a needle, spiritus and cleaned the port, but without success. I tried to turn it on with Power+Vol - , same as I said before.
Finally, I'm going to leave it charging whole night, so wish me luck :P I'm afraid that it's hardware problem with motherboard, but maybe you have some kind of ideas?
