I wanted to know if I install the new service release 5b for CM 4.1(3)will this change the firmware of the phones? We are currently running a engineering special firmware on 7970s and do not want that to change when i install the serivce relase.

Thanks in advance.

If there was a device package that got released between the last rev and this one, yes, it would update the device package which is a mix of all newer phone firmware. Usually when u apply a SR, device pacakge is teh first thing that gets installed.

How would I know what version of firmware this device package contains for the 7970 phones? I tried going through the readme for the SR and couldn;t find anything specifying what version the firmware would get upgraded to.

You can assign on all 7970 phones the existing firmware statically under each phone through BAT so that they dont updated firmware when the server boots back. Thats one way to fix this problem.
