Slow after crossflash

I crossflashed my NEC 3550a to 4551a.

And in Nero CD-DVD Speed, reading a CD is only at 16x. Burning a DVD takes around 30minutes.

I tried to flash it back, but it says that it’s a 4551a and that has to be the real drive number. But then I can’t change it like it says.

Any help?

BTW, I crossflashed to Dee’s 1.Z2.


No help possible here, you are only allowed to discuss this kind of crossflashing in one very thread.

This one:

Ah, thanks. I’ll go ahead.
