Jailbreak
iOS / checkra1n / palera1n
An older iPhone, checkra1n first and then palera1n.
The hard part
Several failed attempts. Apps wouldn’t install, the device rebooted at random, and more than once it ended in a boot loop, but that was the least of my problems cause the damn thing fried its motherboard, i still dont know why neither does my repair guy.
What I took from it
nothing, the same shit will happen tmr i bet you.
