Hi. I installed the system step by step, the wifi and LTE data transfer does not work, even though the transmissions are turned on. Maybe someone can help?

Flash the ROM again, but this time also wipe vendor before flashing.

Any hints regarding SafetyNet or Google Pay when device is rooted?

And may I assume that currently also for LOS 19.0 the same problems for encryption occur as for all other A12 ROMs?

Anyway I appreciate your effort to bring LOS to Cepheus!

Cheers

There are some safetynet fix modules to pass SafetyNet.
As for encryption, you can encrypt your device, but after that you won't be able to decrypt the data partition in recovery.

@Ww222 What about battery drain? Is it better or the same like other A12 ROMs?

Thank you for your work.
