Hynix chip from G930 very often fail on these devices.

among other things, most of the problems with these devices are not software problems. usually there is a problem with overheating of the processor and its bad soldering

you can backup efs (of full dump without userdata and system partition) and try restore firmware via dump write, it may be success
