Failed to Unpack Oculus Go Image

[moocow1452]

Using the unlocked_build.zip available at https://developer.oculus.com/blog/unlocking-oculus-go/ , I was not able to proceed past the unpacking step. Here's my output:

I'm using WSL2 Ubuntu if that changes anything.

Hi @moocow1452 , The file Oculus_Go_SW_Unlock_v1/unlocked_build.zip is OTA package, boot.img is packed inside payload.bin. After extracting boot image from it, I can unpack the image.
