Thanks for the help, however I appreciate the fact that you do not always respond directly, and I have to figure it out myself ...Consider reading the source code of the thing that outputs these errors ^.^
Well. I searched and found these commits.
I don't think anyone else wants a permanent TWRP (but I need one). You just need to include the parameter "ro.secure = 0" in "prop.default".
However, I have one more question:
Where did you get the pre-created binaries (in the “device” ./sbin ./vendor) for decryption? What firmware? And why do they work on old (based on Android 8.1 builds of TWRP 3.2.1 / 3.2.2), but do not work on 3.3.1?
I mean the integration of the recovery disk into the bootram disk. 3.2.1 / 3.2.2 has been installed and works well on LOS16. But 3.3.1 stops when decrypting "data">. <??? (I can't even get a log to understand the problem). Although "fastboot boot yourimage (3.3.1) .img" works autonomously, even with the kernel that I created from the source code of the LOS16 kernel? What is your black magic?
