MAX BR1 Pro 5G can not update modem firmware.

I have been trying to update the modem firmware for about a week.
I am using T-Mobile as my ISP.

Current:03.09.11.00(AT&T,GENERIC,T-MOBILE,VERIZON)
Latest:03.09.11.00(AT&T,VERIZON),03.10.07.00(GENERIC,T-MOBILE)

Failed, Firmware downloading timeout due to low downloading throughput

Is what I get when trying to update. Sometimes at 8% sometimes it makes it to 99% and all over in the middle.

Isn there anyway to get this updated?

Thanks in advance.
