Easy SIM Unlock for the Samsung Galaxy S III

Having your SIM locked doesn’t usually cause a lot of problems. Sure, it means you’re stuck on whatever carrier you’re currently on, but otherwise it doesn’t really hinder things like root, flashing ROMs, etc. That isn’t to say that unlocking the SIM isn’t useful. Those who travel or simply want to remove carrier restrictions can benefit from SIM unlocking a device. Now, Samsung Galaxy S III owners can have their SIMs unlocked so that they may do as they please.

The method comes in the form of a zip that contains a few files that must be moved to the Galaxy S III EFS folder. Released by XDA Recognized Developer zohawkish, the method is very easy to do. As zohawkish explains:

– First you need to backup your “EFS FILE” in safe place.
– you must be in unlocked stock firmware like BLG8 (using voodoo app + libsec-ril.so (mike1986 fix))
– unzip the attached zip “efs.zip”
– copy the files (.nv_core.bak, .nv_core.bak.md5) to your EFS file
– reboot and enjoy !!!

Of course, there are some potential complications. As stated, you’ll want to backup your EFS file in case something goes wrong. Additionally, you’ll have to restore your backed up EFS if you ever want to update to a future Jelly Bean release. Aside from that, users have reported that the mod works perfectly.

Note from the editor: the actual thread is no longer being supported by the OP and as such it has been closed.

New Snapdragons: Some Context & Contrast

It hasn’t been a good year for Qualcomm so far. Every device featuring the Snapdragon 810 has had a less-than-stellar fate, be it because of overheating complaints or actual decreased sales. HTC is in a particularly worrisome situation, and Sony’s Z4 is slipping down Japanese charts just over a week after its release. The G Flex 2, Mi Note Pro and Z3+ all saw complaints as well. Even MediaTek is seemingly getting an advantage over this.   But a particularly...
