Team Synergy, namely TrevE and myself, have discovered a potential stock bootloader unlocking mechanism that may be useful in unlocking the bootloader in the Verizon Galaxy S3, as well as numerous other devices, including but not limited to, the Note 2 and the Galaxy Stellar. This is currently an R&D thread, and its purpose is to investigate the potential of the mod.
First and foremost, if this mod truly is successful in unlocking the bootloader on one or more devices, ALL credit MUST be directed to Team Synergy for the unlock, as it was first posted here by our team: http://forum.xda-developers.com/showpost.php?p=37446000&postcount=16666. Do not kang or try to pass off our work as your own.
Be advised that we have not fully tested this mechanism and have no idea what repercussions may result. As such, Team Synergy will not be liable for any consequences whatsoever.
But those who wish to give this a try on this device or others need to try the following:
Type in a shell:
am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://HIDDENMENUENABLE
Then enable the hidden menu on the device when it pops up.
Then type in a shell:
am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://UNLOCKKERNEL
This should throw up a popup like the image shown above. In theory, accepting this should run a hash check against your device keys, then continue to unlock the bootloader.
This code does not exist on all carriers, but it is definitely present in Verizon stock ROMs. Those who are brave enough to try, please post your results in the thread
