I flashed this file; Galaxy-S-fre3-MB1FirmwareModemAIO.zip, specifically. Is there any way to revive my device without having to JIG it or is it just done for? I was also on a KitKat rom.
If you have a Virgin Mobile SPH-L710, you can use the de-brick image below, otherwise you need to search around Google for one. You would search for "debrick image for <model numeber>".
I got this problem solved with the help of zachf714, invisiblek and a special thanks to xstefen for providing a working debrick image. Here is the link to the working debrick image that xstefen provided: http ://download.xstefen.net /getdownload.php?file=./xstefen/mmcblk0_backup.bin.zip. (Remove spaces) all you need to do, is write this image to a micro SD card using linux's
command or Win32 Disk Imager. Then put the sd card in your phone, boot into download mode and flash a stock ROM using Odin.
Wish anyone else who have this problem luck.
P.S. I am not responsible if anything happens to your phone because of this.
