			== Conclusion ==
			To sum up, in a nutshell, I installed the latest Android version (8.1 Oreo) on a barely alive phone. To accomplish that I unlocked bootloader, flashed custom recovery, installed ROM itself, installed Google Apps. After that, I restored Contacts and other data and tested basics functionalities of the phone. Hackers Keyboard and Termius were also installed from Play Store to provide a more convenient way of managing the phone through the Shell interface.

			Word of Advice? Do your research if you don't want to brick your device.
