Sorry for not paying attention to this thread for quite some time. I've got a copy of the old firmware here since the other site is long gone:

Download this ISO, burn it and you should be good to go:

Thanks very much. Was able to get the ISO image from this thread and was able to burn a copy on a CD. However, I am stuck as I could not press "YES" to confirm the update since the touchscreen is unresponsive. How were you able to do it on yours?

Your steps in the original thread is very helpful and gave me hope. I hope you can give assistance on this minor set back.

Thanks in advance!!

RHR 730n screen calibration
 

Has anyone found out any way at all to get in to a locked calibration screen on the RHR 730n? All the firmware versions I've found for the RHR starts with 2.### so I don't think the 9.### downgrades will work on it. I can get to the engineering menu using the hard keys on the side but since the screen doesn't work, can't page down and select "screen calibration" via the soft keys.

Is there maybe a way to jack some kind of external controller in to the resistive touch screen port where the circuit ribbon connects? I can't find anything to fix this issue for RHR anywhere on the internet. Stuck. Radio works but touchscreen is tweaked.

so? It’s possible???

I have same problem. i can burn the CD, But i don't have way to press "Yes" bottom.

I know it's an old thread but doesn't seem to have been solved here (or anywhere). Has anyone ever figured out how to press "YES" on the update

I'm stuck on the choose yes or no screen.

any options to choose yes if the screen's not working?

Tengo el mismo problema hace ya 7 años-...Mygig REZ....version 9292....aun no puedo presionar SI.....
Alguien lo ha resuelto.???
