What I just roughly tested.
- Download the update.zip: http://www.mediafire.com/?hxmkxdafhkahi41
- adb push <zip name> /sdcard/update.zip
- adb shell
- cd /cache
- mkdir recovery #it may already exist
- cd recovery
- echo '--update_package=CACHE:/recovery/update.zip' > command
- cat /sdcard/update.zip > update.zip
- reboot recovery
Please do not repost this right into your blog. Last time you guys did that, my instructions had an error, which got corrected. On my site at least. But not in all the copy-pasted locations.
