Once it tried to reboot, I ended up with a white screen that shows a dew lines of text (I attached a picture).
If I try to go into download mode, it will flash for a quick second and then go right back to the white screen. I can't seem to get into the recovery either. The website that gave the instructions for flashing TWRP talked about a similar error on Sprint phones and the cure was to flash the kernel again, but I'm not really sure how. The phone will respond to commands in fastboot, i.e fastboot reboot, but it just goes to the same screen again.
Please help, I'm a little stuck. Can I use fastboot to flash the kernel, if so, how?
