Rv50X Radio firmware

I am trying to update aleos to 4.15.3 but when it gets to the radio firmware version its asking for another version that is not available on the Sierra website. If I install Aleos without the radio firmware the modem reboots to bypass mode.
Radio firmware available on sierra-7455_02.33.03.00_VERIZON_002.079_002 (4).iso
Radio version its looking for- MC7455_02.24.05.06_VERIZON_002.034_000.iso

Hi @gebsafety1 ,

I just rechecked the ALEOS, the requirement about radio firmware Sierra is correct.
Where do you download ALEOS 4.15.3 from the source? Can you share with me the screenshot of the issue?
