IR Code for Comcast DC50X DTA

Having trouble re-installing 0237 code for Comcast. I did down load COMCASTDTAir Codeoverwite0237 50005500.zip file, this was a great overwrite the first time I used it , and it worked, now after doing a factory reset the 0237 code was no longer there, I removed the HDD set it all up to the pc same as I did the first time, used the .bat file, and I get overwrite failed, tried some of the other zip files just to see if they would work, no same failure, tried to install it via Wirns, (cp -f /name/storage/Photo/install/C0237fi.rid /name/system/user/mirror/sys-setup-gaea/data/irCodeset/C0237fi.rid) can't seem to get it work with the 0237fi.RID file in the replay photo/install file as directed. I have no clue how to overwite the HDD with a new ISO file or use Linux . Is their anyone out there that my have another work around.

Thank you for the 411, my replay will not let change both dns1 and dns2 to the same number at the same time. I'm still stuck for answers, again I lost my 0237 code when I did a factory reset. I also tried all of the other dns address's 107.20.245.128, again my replay will not take both address at the same time in dns1 and dns2. Also the ComcastDTairoverwrite does not work either???????

Thanks I'll give it another try

O.K., I'm sorry but this did not work for me, I followed the instructions, got into the site, then went to the replay site for an update, when it completed the down load I could not go back the network settings and change the dns addresses , did this a few times, no luck. I watched the video, same problem. I also tried a different HD, no go?????Need more help!!!!!! Please
