You downloaded the wrong file.  The file you wanted to run has "rp1" but the original file doesn't.  You downloaded a file for a different model.  Your router is an ASR 1001 with fixed RP but you've downloaded a file for a different sub-model of ASR, like the 1002 or 1004.


Go here instead:

in addition to that, it seems like a downgrade rather than upgrade. Once you have the correct image, you need to change the boot system command to use the new image and negate the old one, or add it (the old one back) after, to have backup image in case it fails.
