Hi I'm having the exact same problem
on Drive 51 HWID 2586 Firmware 440.gcd
original firmware 380.gcd
Could someone make me a SD Flash kit with FW3.8
I have tried moving a patched 380gcd into the system folder with unit turned but it didn't work on restart.
Should i have removed the xml file first ?
Or should i have simply edited the xml file to say SoftwareVersion 370 SoftwareVersion
