My branded o2 Desire has this on it and there's not much I can do with it without downgrading to 0.80 I think.

if you are on 0.83 update the official FroYo OTA so you have 0.92 and then downgrade to 0.80.

i can't confirm that it's possible with 0.83

I downgraded.
Uninstalled htc COMPLETLY
installed the unrevoked android usb driver
rebooted
turned usb debugging on started unrevoked in admin mode
and it still fails.

before i upgraded to 0.92 i used this method 1 milion times and it always worked.

i think i had a similar problem while rerooting / custom recovery.
Try to downgrade again and remove all update.zip files from your SD card before.

It's a branded phone so I can't get the OTA update, and I can't debrand on 0.83 as far as I know.

But now I dont manage to flash LeeDroid ROM.... (signature error) and I tried with 2 new goldcard...nothing to do. I'm stuck with the 2.1 OS :(

If using clockwork recovery, there is an option somewhere to turn off signature verification.

To use unrevoke you need nothing on you SD card because the files are going to be pushed through the unrevoke program.

if you are talking about the downgrading you only need the PB99IMG.zip on your SD.

For unrooting after custom recovery with unrevoke you need a custom ROM zip file which you can apply.
