The ‘Marvin Wißfeld Team’ has also created a LineageOS-21.0-for-mircoG version for the wade Android TV Box. Although it boots, it gets stuck in the animated LOS logo and cannot be operated.
The target sabrina Chromecast with Google TV unit must be manufactured before December 2020 and the running firmware version needs to be below the February 2021 patch level. This is because newer units come with a bootROM password protection mechanism, and Google enabled a similar mitigation policy on older units in the February 2021 software update.
The chances of getting hold of this TV box are likely to be slim or there will only be a small number of users.
