> That said, there is also a free L1 Content Decryption Module posted in the ‘LenovoTB-X505X-L1-KEY’ repository. A trusted source confirmed to TorrentFreak that this CDM is indeed working. However, as Widevinedump also notes, it may not be active for much longer.

That key was revoked the day the article was published.

A noble sacrifice. Some paying customers will be affected, but it's for the greater good.

The streams will continue to get dumped, with different keys.
