I have a Bell Z Ultra
When I check online apparently Z Ultra is on 4.4 and when I use the PC Companion app it says my device is up to date. Anyone know what's up?

You have to relock bootloader first if unlocked

Using the *#*#7378423#*#* to get into the Service Info it displays ""Bootloader unlocked allowed: No" so I'm assuming it is indeed locked.

Dont you need a unlocked bootloader to do so?
If not, which would be the best one for my model, it's LTE.

Not to flash a FTF (pure stock sony firmware) just find a c6806 .757 FTF and download the latest flashtool, see the stickied guides
