WIP
- The hangs on startup unless systemd-journald is masked:
- adb shell
- mkdir /tmp/drd
- mount /data/rootfs.img /tmp/drd
- chroot /tmp/drd /bin/bash
- export PATH=/usr/bin:/usr/sbin
- systemctl mask systemd-journald
- Samsung does not use fastboot. Instead heimdall is needed. The boot image can be flashed in download mode with: heimdall flash --BOOT hybris-boot.img.
