4. Loading a pac file may took long depend on file size. After loading a pac file, now ready to start flashing, You can also click on Settings on two gear icon if you want to unchecked some part of firmware like EraseRuntimeNV, This will not work on lower version.

5.  Turn off first your phone, remove battery (if removable) then bring it back. In ResearchDownload/UpgradeDownload Click on Start Downloading, then in your phone press Volume up and Volume down then connect USB cable.

After you flash the firmware, you can now turn on your phone, take note that first time start up may took long. but if it tooks more than 15 minutes then I suggest to perform a hard reset.
