X-Gold 618 Unlock

Possible Methods [edit] Class 1 Find an exploit in the bootrom to break the chain of trust. Improve by several orders of magnitude the NCK brute forcer, and find a way to extract the CHIPID and NORID Find the theorized algorithm of NCK generation [edit] Class 2 Use a SIM hack such as the TurboSIM Unlock Find a way to patch running memory to "unlock" the phone on every bootup. This is how ultrasn0w works. Find an exploit in the Baseband Bootloader so you can downgrade the baseband, then use ultrasn0w. Geohot and the iPhone Dev Team found (independently) an exploit in bootloader 5.8, but it isn't useful enough as only very-early (week<30) iPhone 3G units have bootloader 5.8.
