Xiaomi 14 Ultra is unable to update (Global)

[hellojog]

I recently got a Xiaomi 14 Ultra Global version however I am unable to update using the updater app or the Mi Assistant tool
When using the Assistant tool the update begins and gets to 4.99% where it will stop and the phone will eventually reboot and not update

When I download either the OTA or the full rom with the updater app it fails at extracting.
I have even manually downloaded the rom verified the archive is valid copied it and tried installing it using the advanced options in updater.
I enabled logcat and am getting error code -7 from updater which I am unable to find any information on.

I have tried factory resetting and then updating again but am still getting the same issue.
Have I been scammed and this isn't actually a global device? The device is locked/secured so I am not sure how that would be possible?

I would like to have the bootloader locked however would my best bet be unlocking it and installing a fastboot ROM then locking it again? I am just scared that it'll brick if I do it if it's not really a global device.

More log cat attached (I can't post it because it's flagged as spam)

You can check if your device is Global.

Welp I guess I am screwed.
How the hell can they install a global rom and lock the boot loader on a CN device?!?

The rom has been modified.
The only solution for you is to flash a Cn rom (edl mode) not free, then use a third party paid service for unlocking.

Ah crap so I can't even unlock and install the xiaomi.eu rom or even the original CN rom
The pricks want a 20% restocking fee they made no mention of it having a hacked global rom
I couldn't use mi assistant to flash the CN rom could I or would that likely brick the device?

There is nothing you can do except what I wrote above, any attempts will fail or brick your device.
