Modifying without root.

In case you need to modify system / system files without root.
Requirements twrp recovery.

- enter into twrp recovery
(start device in bootloader and choose recovery)
- mount /system/ and /data/
- go to advanced - terminal
- due to fact that system is not fully secured, you can perform operations that normally require root priveledge
hopefully, you understand what you delete or modify.
Recommendation: create backup of your system, before any manipulation with system, otherwise device may not survive at next boot.

Thinking: might be next step for cid modification on s3 device.
