Hello.
I have used lovely Devo 12S with deviation 5/0 version long time.It's nice TX and very satisfied for me.

However, My Devo 12S has some problem recently changed cr1220 backup battery with re-installed 5.0 version through Devention DfuSe USB upgrade tools
As seen attached photos(photo 1), It has black background with can't enter Menu section for changing the TX configuration, and binding with RX.
I have tried upgrade(5.0 version) and downgrade (4.01 version) firmware, Lib, files many times, But all of same can't enter menu.(sometimes 4.01 version showing normal main screen, but can't enter menu section)

However, clicked some of area in screen, I can enter mix menu, and model menu only. (photo2)
Tried installed original firmware, It's only problem broken main screen, other thing worked perfectly

Tried using DfuSe demo v3.0.5 program with verify option.
As seen photo,(photo 3) address 0x08004000 error showing msg box.
I think that address of my Devo12S flash memory can't write or erase.
need jumping this address or sealed this address for solving problem

Please someone help me how do solve or fix please

Was the media.dfu file for version 5 also loaded on the devo, or could you reload the media.dfu again with Dfuse (under library!) to trace this problem. The background image is a file of the media.dfu.
