There’s a known bypass for some older Samsung phones that involves literally — putting it in a freezer for 10 minutes, then booting into download mode. The cold slows down the NAND read speed, causing a timing mismatch in the FRP check, and the phone skips verification. Yes, that’s a real exploit.

They exploit hidden test menus, TalkBack glitches, or combination firmware files. device fixer frp
