revanced-cli VS aapt2

It means that your device uses ARMv7 which is currently not supported. For now you can patch on an ARMv8 device and then export the APK to the ARMv7 device or you use a PC to patch with the CLI.

either patch on PC or an ARMv8 device and then share the patched apk to the ARMv7 device.

By using patch options which only exist in the CLI

I assume using this: https://github.com/revanced/revanced-cli

NOTE: You're advised to patch your own version of YouTube when using ReVanced, either by using ReVanced Manager or ReVanced CLI and not download from other sites. For help, you can check out r/revancedapp.

You could try using the Command Line Interface if you have Java installed, the README has a documentation on how to use it and I'm available if you need help.

Is that this? https://github.com/revanced/aapt2 ?

After searching a bit, I found the solution. There is AAPT2 binary compatible with ARM (both 64 and 32), you just have to download it separately, and when running reVanced CLI you have to put the arg: --custom-aapt2-binary= (for example, --custom-aapt2 -binary=/home/kali/Downloads/revanced/dist/arm64-v8a/aapt2) and problem solved! It would be great if in a future release of Revanced Builder, you could put an option, to choose ARM OS so you can use the custom bin.
