Mio Moov M410- I have found method how to enter Upgrade screen, but how to unbrick???

[Cornholiogsm]

Hello,
I have one bricked Moov M410.
It has overwrite AppStartupSec.exe with Systeminformation menu...BUT...
menu has wrong entered addresses for launch igo8
Of course USB don't work.
So i have disassembly this mio for searching how to access to upgrade screen and i have found it.

1) Turn MIO ON (disassembled)
2) Connect USB cable between Mio & PC.
3) Unsolder red battery + from mainboard (stay connected with USB)
4) Short on board + red and - black battery pins ... mio turns off and led diode blink orange/green
5)Press reset switch for approx 2 seconds
6)Press and hold ON/Off for approx 10 seconds
Now is mio on blue screen with text

"Please send the Image through USB"

But what can i do now ? I have installed drivers for SEC SOC SMDK board and then run DNW.exe. On dnw is USB:OK, but i cannot flash any firmware - i have tried moov M400 fw.

Can You please help me?
