Help Me Make A Custom RC30

---

I have applied the custom recovery and boot images to my phone.

I have downloaded the RC30 update and removed boot.img and recovery.img and removed them from the manifests and update script.

I resigned the update with the tool provided in the zip with the custom recovery and boost images. I had to comment out the beginning of the script where it checks the fingerprint of the phone.

It is verifying the image and applying it, but is constantly failing on the same thing.

The patch system in this update seems to have alot of issues. Try the full one at https://android.clients.google.com/u...+RC28+RC29.zip

There is no applypatch binary in that update zip.

I already have RC29 on there, I am trying to make a RC29 to RC30 update patch that will allow us to keep root.
