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.

Open War for Open Android: Antitrust for Cyanogen?

Android and openness is something we talk about all the time, but the recent developments in the industry point towards inherent flaws with this very premise. Be it from bloggers, political institutions or corporations, Android is seemingly not open enough. The “War on Openness” is ironically becoming an open war, where many players are increasing their stakes and scope to try and land a bigger hold - or at the very least, restrict Google’s - on what is the world’s...

Diving into the April 2015 Material Design Update

Before the release of Android 5.0 Lollipop, the Holo Design guidelines served as the official reference for Android design, right from IceCream Sandwich to KitKat. However, updates to the guidelines were few and far between, leading to a lack of synchronization between Android design and current UI/UX trends. Google seems to have learned from their mistake the last time around, and earlier this week, a significant update was released for the Material Design guidelines, marking the second revision in less...
