Help... I think I hard bricked my phone!
My phone was having some problems flashing ROMs so I tried everything to get it to flash. It would only flash Samsung ROMs, no CM based ROMs. One of the things I did was to flash a modem/bootloader that was for the T999; I have the T999L. After it successfully installed, I rebooted my phone and it never turned on again. I tried holding the power button and multiple combinations of the volume and power buttons with no success. I tried switching out the battery with no success as well. When I plug it into the computer with a USB cord the red LED light comes on and the computer makes a sound. Other than that, the phone wont turn on. I was running 4.3 Stock ROM before it was hard bricked, was rooted and had TWRP 18.104.22.168... Please help.
