Is there any evidence that Widevine L1 itself is actually broken, instead of let's say Netflix still offering legacy routes to provide HiRes content to some STB's and other devices (routes which are then used by pirates to download the content)?
You're supposed to buy new devices, consume.
This happened more often in the past than people may realize, especially on devices from Xiaomi, Oppo, OnePlus.
Netflix is actively monitoring this and are escalating to device-vendors as soon as they see suspicious load and are about to flag the devices.
> 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.
The streams will continue to get dumped, with different keys.
