If you are trying to use Maximus or a couple of the other ROMs that say 2.16 hboot needed, then you need to follow the install instructions exactly on the Maximus first page.
Where it says to put the rom.zip on your phone, install zip. Download firmware on pc and install onto phone. Download only the TWRP on Maximus install page and flash that. Then reflash Maximus ROM.zip while in twrp recovery.
Here is a copy and paste of those directions
Download ROM and put it on internal sdcard.
Put device in fastboot mode (Power + Volume Down)
Find in Recovery "Choose zip from sdcard" choose appropriate zip file.
Proceed steps that Aroma installer gives.
After install finish you MUST reboot device in fastboot mode.
Now it's time to install 4.2.2 capable firmware.
Download Install package.rar (Archive stored in same folder as rom)
(Note that fastboot.exe not capable yet with Windows 8.1, you need Windows XP/Vista/7/8)
Connect device to PC and make sure you see lines Fastboot USB.
Extract Install package in any place on your PC.
Open folder, run Command Prompt, type there
1.fastboot oem rebootRUU
2.fastboot flash zip firmware.zip
If you get an error
FAILED (remote: 90 hboot pre-update! please flush image again immediately)
type command once again
fastboot flash zip firmware.zip
fastboot flash recovery TWRP18.104.22.168.img
Make sure that installation was successful and press enter to reboot device.
Device will boot in system, wait till you can see device on PC and copy ROM on internal SD card once again.
Repeat ROM installation with Aroma installer, do wipe during install.
Congratulations, you have device with fully working Android 4.2.2 and Sense 5.0
