Help Problems Flashing Gu 87

[willy salazar]

I am trying to flas my GU87 with Winmodo3-3 I have pins 4 and 10 isolated
The software reads Signaling and then Changing Protocol and that it's
Also I get the phone front light flashing green with a message
FLASH LOADER
GD87 VERSION 1.4
Invalid Command
Is there any difference that my phone model said GU87 is a AT&T Phone
Thanks in advance for any help
Also I am using Panasonic Data Cable Model #EB-RSD67 looks original
Thanks again
