My Sony M4 Aqua suddenly turned off while I stream videos, when I turn it on again it's now stuck on blue wave. I tried Pow + Vol Up + Down to hard reset but it only vibrates then nothing happen. I tried to use Xperia Companion but the program can't detect my phone ( Press Vol Down while plugging the cord to computer right ? I did that many times but even while I waited for like an hour, it can't detect it so I can't repair ). No it didn't restart while it's on blue wave, its just keep going. Please help.

Sorry if my english is bad.
