I've seen many videos online, DO NOT REBALL.
do you even know why some people do that?
Because when the CPU die, the heating from 120 c will fix the CPU temporary, however reballing will require more than 160 c to melt the connectors.
Applying that much heat to the CPU will cause problems in the future.
The solder underneath the CPU is poor lead free which causes the ylod a reball properly will fix it
