clone stock dpc2100r2 to stock dpc2100

First off I want to thank drewmerc because I found a post on here were he helped another member flash his dpc2100 to stock. I am using my dpc2100r2 stock on Comcast now and I was given a dpc2100 last year that was bricked and no backup was done by the prev owner. I decided to pull it out and see what I can do with it and I used your files and flashed the bootloader then image1 and then my cfg (nonvol) from my dpc2100r2. What is weird is that the modem that was bricked is labeled a dpc2100r2 but my dpc2100r2 backup wouldnt work on it but your dpc2100 did. I had to short the tsop out to reflash it but it worked.

My question is, would it work like this if I had to use this modem as a backup or should I just flash Haxorware to this modem and play around with it?
