Htc Magic 32B locked in Splash Screen

Hello to all ,
Yesterday my friend received a message on his Magic that proposed to update the system. He did the upgrade, but something went wrong and the phone is locked in red Vodafone splash screen.
I was reading and trying various things, with the following results:
adb not recognize the device, the command fastboot tells me: FAILED (remote: not allow). The same on Linux and Windows.

By combining keys, I can access on the phone to fastboot and Android System Recovery.

Anyone have any ideas I can try to return to normal?
Magic data are:

Sapphire 32B SHP S-ON G,
HBoot 1.33.006 (SAPP 10000)
CPLD-10
Radio 2.22.19.56I
Unlocked and no data plan.

I read a little more and saw the error (fastboot remote: not allow) is caused by a "perfect spl" (I guess)

And to solve this I need to create a goldcard and other things, which is impossible since adb does not recognize the magic. I'm going the right way?

Thanks in advance !
