I`m tring to update a host from esxi 5.5 to 6.0 U1, i prepare a USB and a CD and both does the same.
The boot process get stuck on a part that says
RSTE Loaded Successfully
Hope you can help me
Do you see any error in ALT+F11 screen
Can you try esxcli software profile update command to check whether the upgrade goes through smoothly or not?
