My galaxy s4 has recently been very slow so I thought that I would try a factory data reset to clear some things up. However, my phone is rooted. Now when I looked around on some other forums it seemed as though that I didn't have to worry about factory resetting the phone while it was rooted. But when I went ahead and did so it no longer will boot. Its stuck in the boot loop/download mode/ whatever you may call it. I can't seem to flash a recovery file through Odin either. I need some help for fear that my phone is gone now.
