7. on intel tool click on brows and located the Rom, wait for the tool to unzip it,
8. do not change anything just click on Flush and wait for it, on the middle of the process the tablet will ask you if its ok to wipe user data choose yes
after that the tablet will reboot and finish the installations and power off itself, power it on and wait for it, its will take long time for first boot so do not power it off.
