It may have been posted somewhere earlier in the thread but this is where I downloaded it from.  See post# 1842.

Then un-rar DS2000Update.GEL and load it.
After updating apply a key generated with DSAR DSHH to enable all options.

Be aware that so far I haven't been able to downgrade back to .02 from this version.  Refer to my post above regarding the issue.

Success!  Updated the post.

As mentioned a few times earlier in this thread (and at the DS2000 Review thread), I (and others) have upgraded and downgraded between the versions several times - always by bootloading, and always taking care to clear the FRAM when next booting.

Tasman:
Do I need to uninstall my previously applied options before upgrading to the new firmware and applying the DSHH generated key?

I didn't, although I have an official key for the normal options; I just used cybernets DSEA for CAN decode.
So I don't think it's necessary to uninstall and reinstall all (since I don't think the FW can distinguish between official and "non-official" key codes) unless you want to do it that way.

But, more importantly: Rigol has changed the the structure of unit settings stored in FRAM, so if you upgrade/downgrade between the major versions (v.01.XX.XX.XX to v.02.XX.XX.XX - or vice-versa), it's highly recommended to hold in the left-menu F6 button (sixth gray button down on left side of LCD) during the first reboot after loading (to clear FRAM) - otherwise the DSO will hang (often) when switching between various menu items.
