[x9007] Bricked, need help

My x9007 had issues with 3G network so flashed a modem file from oppo fourm; the screen went off immediately after flashing was completed. Now no reaction from the phone,not showing anything even if I connect to charger and not even a single vibrantion. I did find some unbrick I in methods in oppo fourm but they result in flashing upx9006 rom. So any specific way to unbrick my x9007? I don't want to throw this mobile coz it is the best device I has till now. And can't afford for a new one. Please
