[Q] Making a Goldcard when stuck at HTC logo while booting

Hey Guys, i wanted to ask if there is a possibility to make a Goldcard to rescue my Desire HD
I bought it on Ebay and it does only boot to the HTC Logo on white screen...
Some Facts:
-Its a Vodafone DE CID so i cannot take a RUU because it does not exist...
-Fastboot works, is detected on PC and may be the only way to access the phone.
Thanks for your Attention

Go to fastboot and type fastboot devices in a cmd prompt

Can't help unless u do that

Hard bricked HTC 616 dual sim

Long story short, I was flashing my HTC 616 dual sim, and I clicked the "Format & download" button.
The phone now won't power up or charge; but still gets recognized by the PC ( I hear usb connects) and it accepts flashing.
I did a memory test using sp flash tools and it showed me this error when testin EMMC:
BROM ERROR: S_DA_MT_DEDICATED_PATTERN_ERROR (0xC1B)
[H/W] DA detects error on the phone while memory test with dedicated pattern!
Please ask for help.

If it shows "mt65xx preloader" then download the firmware from below link and flash
