Need the north America firmware for my bv6800 pro . It restarted and boot looped for no reason so I downloaded a new firmware and it isn't for north america, actually I can't find a north America version. Mtk engineer mode in band modes don't show the right bands. I need bands wcdma-pcs-1900, wcdma-aws-1700, wcdma-clr-850, wcdma-gsm-900, lte bands 2,4,5,7,12,17,41,66. Everything I've tried has failed. I even bought a bv5500 pro to replace it but I honestly don't like it as much as my bv6800 pro. But right now I have the equivalent of a really small tablet without being able to use my service provider. Please help.
What I've tried so far...

I've flashed my IMEI from my blackview box and it worked giving my IMEI back but not service

I've flashed the md1img.img, md1dsp.img, md1arm7.img, and md3img.img from other mt6750t phones like the leagoo t8, the Asus zen phone max plus, and different bv6800 firmwares I've found online to no avail.

Tried the h4_r5 fix to no avail

Tried to copy firmware files from unpacking the system images of the leagoo rom and the Asus rom and the bv5500 pro rom to the bv6800 phone to no avail.

The bands just won't change or unlock. Please help me.

Here is the latest North America ROM of BV6800 Pro:
