Once the new firmware is flashed, enable USB debugging and push su and the root script. Pay attention to the paths, do not push to a different path or it will not work.
adb push su /data/local/tmp/su
adb push jc.sh /data/local/tmp/jc.sh
adb shell chmod 755 /data/local/tmp/jc.sh
adb reboot
Would somebody please help me understand what I do here? I believe the flash went through perfect..it rebooted my phone up and now I have no idea how to understand this next part...
