xperia m2 help

hi, my xepria m2 d2303 wont take any charge, i have replaced the battery and it still doesn't receive any charge, i did root the device before it stopped working and i did install multi recovery, but i cant even boot into recovery, no charge lights show red or blue, the problem happened whilst i was playing a game and connected to charger at the same time. I noticed the phone wasn't charging, so i stopped playing the game, then my phone died and it wouldn't turn back on again, i did have the same problem before with a huwaei y330 running on stock firmware with no root or anything, i have tried different chargers but still nothing, is the phone truly screwed or can i save it ?

Edit: i have tried the reset switch/button to no avail

oh the xperia m2 was running stock firmware if that helps.

many Thanks
