I just recently installed Omega ROM on my phone and upon installation finish it asked me to restart, and I said yes, and it shut off. Now I’m not able restart the phone. I’ve held the power button for more than 10 seconds and it still does not turn on. Download mode does not work, recovery mode doesn’t either. I don’t even know what to do, because pluggin my phone to my charging cable doesn’t even let my phone show any lights. My phone is a Samsung Galaxy S III (SCH-I535). I installed the ROM very carefully and I have no idea what I could’ve possibly done wrong. Thank you so much for your help.
