I am sorry my Recovery isn't working for you. If you could provide a little more feedback, I am pretty sure I could resolve your issue.
What update are you referring to?
What version of my recovery are you running?
What error message did you receive?
By default, my recovery is setup to flash updates with signatures embedded in to the update file. I believe this is something that Google added to Froyo, and is used for their official updates. Most mod developers do not use this feature and this may explain why using my recovery fails--its checking for signatures that do not exist and fails to install the update. However, I anticipated this issue and added a feature to my Recovery to disable signature checking.
If you happen to give my recovery another shot, you can verify that disabling signature verification resolves your issue. After you start the recovery, click the menu item: "apply sdcard:update.zip." Afterwards, click the menu item: "disable signature verification." After its disabled, you should be able to apply your update.
In my future updates, I will most likely modify the recovery to make it more intuitive to prevent any confusion.
Thanks for the feedback guys!
