last night i was trying to follow the instructions on efi website to do the june 22 update. i could not find the proper firmware numbers so i asked on the forum. i was told to install 7.5.4 before i could do the ungrade as it was contaned in that version. so i did this this morning, and i went to go forward with the firmware update and it says my firmware is now 2.05.xx and i need explorer to update it. ???????? what is explorer and where do i find it. i am very unsure on what is going on here and scared to hook this to my truck. please help
