Verizon is known for locking down bootloaders on its handset to prevent users from flashing, rooting or modifying the handset in any way. The Samsung Galaxy S3 was no exception to this, and came with a locked down bootloader angering many of its early owners. While Verizon and Samsung did announce a developer edition of the Galaxy S3, it made little sense since it came without any warranty, and had to be purchased outright.
The Verizon Galaxy S3 developer community through its hard work had managed to gain root access, and even flash a custom ROM including CM9/10 on the device. Now, in a major break through, AdamOutler has managed to unlock the bootloader of the Verizon Galaxy S3. He managed to unlock the bootloader via an unsecure bootloader leaked by an “African-Canadian Sock Monkey”.
If you ever flash this unsecure bootloader on your Verizon Galaxy S3, make sure you never install an update from Samsung or Verizon. Doing so might just brick your device. Flash the unsecure bootloader only if you are willing to run custom ROMs on your Galaxy S3 for life.
Head over to this thread on XDA for more information and how to flash the unsecure bootloader on your Verizon Galaxy S3.
Kudos to AdamOutler for doing an excellent job and the “African-Canadian Sock Monkey” for the leaked bootloader!
