OK, out of the new spares I had, (2.8" N95 8gb lcd & slide mechanism and a N95-1 with a smashed screen) I put the 2 together, and ended up with a N95-1 with a 2.8" screen.
The only problem is the screen is blank the keys for the media player buttons light up but not the keys below the screen. The phone work perfectly as I can connect to it from my laptop and also make calls from it.
I am not sure if it is possible to get this to work, I would like to just out of curriosity.
The only thing I can figure is there is some thing different between the firmware for the N95-1 and the N95-4 when it comes to the display drivers. I was going to force an N95 8gb firmware upgrade on the N95-1. I have the firmware but not the tools to do this.
If you guys can think of any other route I can explore to maybe get this working I would really appreciate it.
