R7 BEB-8591A-50 EU Write attempt fail

I am making this new discussion to help those who are trying to flash the r7 with this specific EU map (BEB-8591A-50)

I first try to flash the ecu with the unrestricted map it will try to bind license first then it will fail and the prompt message will say "Write attempt failed. Please try again." Tried again to no avail, I restarted my computer, check USB driver, Reset Windows, Updated windows, Tested bench interface, Tested 6-pin cable. Tested power supply to the bench, switched from a breaker directly to a wall outlet, Switched internet service provider, switched location tuning (went to a friend house with another different internet service provider). STILL NOTHING.

After going back and forth with support which I thank for trying to help, They have given me certain instructions which didn't work. (Extremely Frustrated at this point because when I wake up its FTECU Closing time, I live in Asia.)

What I resorted to is flash the stock image of the -50 EU map and it allowed me to bind license and write ECU successfully. I then copy the TPS Vs RPM mapping, IGN Maps, and other parameters over to the stock map and save as a tuning file. It works great. After a 4-5 writes I try to write the ecu with the unrestricted map -50 to test out if it works after a couple writes with FTECU coding. This again resulted in a write attempt fail Please try again prompt.

So this means that the unrestricted map for the -50 ecu is defective.
