Advertisements TE 3 works perfectly after roll-back, but can you go back to Hydra? Maybe not. At least not on my machine so far. My device is the 500GB Bolt Vox for cable and antenna recently bought directly from TiVo. The "Experience" App is found on the Bolt after roll back, but when I ran it, the Bolt went through a connection and a supposed download, only to remain in TE 3 after all the steps ran, and I was prompted to press OK. The result was... nothing. Is the downgrade now meant to be irreversible?
