doesn't look to me like you followed the instructions, that doesn't look like an android build log

you need to build from the root of android, not from this folder

ok i succeded to run it and after i run "adb logcat -s recowvery" it got stuck with the following output:

--------- beginning of system
--------- beginning of main

You might notice that the branch is called android-6.0 There's no point in building this for devices newer than that and I won't support it either as the exploit has been patched by then. Android's libraries and build system makes drastic changes every major version. I can't just go adding support for new versions of Android every time one releases. This repository is only for the LG V20.

I compile this with the TWRP minimal build environment for android-6.0 as it has everything needed regarding dependencies for building native system binaries.

Try running logcat -s recowvery directly in an adb shell on the target device:

adb shell
logcat -s recowvery
