A SOLUTION WAS DISCOVERED

So... I've no clue if my LTE connectivity is worse then before and since I'm scared of bricking my device by reverting back to the canadian firmware...
I've got a canadian G6 so I compared both of them and.. even tho the Band 4 had weaker signal, the G6 still picked the Band 4 over the Band 2 that my phone picked.
(I know that my network band 4 is way faster then the band2, so maybe that's why it's still using it even if the signal is weaker)
Based on that, I've been playing around, trying to get the H933 modem file to work with a converted phone and behave like my G6.
First of, I don't have my original modem files (the 3 bin files). I tried to flash the modem partition using PARTITION DL with LGUP. It doesn't flash it and prompt an alert about a risk of writing of 4 differents partitions.. From there, I assume the partition scheme for the H933 is not the same as the US998. (And I know a lot of people reported it just bootloop the device which makes sens at this point.)
I gave up on flashing the modem files for now and played around with the build.prop file.
US99820a04 vs H93320e00
First, I looked at the difference in the Global Canadian firmware and the us998 firmware
I handpicked some of the differences and tried them directly on my phone (using a rooted file explorer)
this change was just a test to see if I get the option to record in the phone call app
But, sadly, it doesn't change anything so It's not valuable and i'll probably revert it back to false.
From there, strangely, I got different elements appearing in the stock OS and the icon from indicating LTE changed back to what it was before the conversion.
So I can assume one more thing, the US998 system should have everything that is needed to behave like a canadian device
The last step would be to flash the modem partition using dd
dd if=/sdcard/modem.bin of=/dev/block/bootdevice/by-name/modem dd if=/sdcard/modemst1.bin of=/dev/block/bootdevice/by-name/modemst1 dd if=/sdcard/modemst2.bin of=/dev/block/bootdevice/by-name/modemst2
But I don't have access to the modem setting file.. But I know erasing them should be fine.
BUT! this command doesn't work on my device, so i'll have to do this :
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst1 bs=16384 dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst2 bs=16384
And the next concern is.. the modem file from the H933 is smaller then the US998 modem file.
H933 : 98,422,784
US998 : 98,947,072
But, since it's smaller, I assume it's fine to flash it over the US998 modem partition
From there, I assume, everything should work as before.. right?
Just posting this here because I'm not sure of some stuff.
