grub.unsquashfs (part of squashfs-tools)..zip file from @IcedCube's original post, and extract it to the root of the USB drive. This will bootstrap syslinux EFI onto it.android..iso in an archive program. Extract the following files form the root directory of the .iso image to the USB drive's android folder ( ramdisk.img is not used in Android 10+ ):initrd.imgramdisk.imgkernelsystem.sfs to a folder somewhere, such as /tmp.cd) to /tmp. Run ls and confirm that system.sfs is shown in the file list. If there is no output, start over as the file is misplaced.unsquashfs ./system.sfssquashfs_root.squashfs_root and run ls. There should only be one file - a system.img inside the directory. Copy the file to the USB's android folder.squashfs_root. The structure is a complete Android root filesystem. To install Bliss OS, the files will need to be in a system image. The following steps will guide you through creating a 2 GB system.img file, formatting it, mounting it, and copying the contents of squashfs_root into the new disk image.sync command might take some time./tmp/system.img file to your USB's Android folder./mnt or /media (ex. /media/USB).cd into the android folder.ext4 disk image, but will be enough to run Bliss.syslinux.cfg and add them before the initrd=/android/initrd.img statement.
