Galaxy S 3 (I9300)
Type of work:
<@dllud> Any idea if that unlock method works on GT-I9300 with EFS v2? <@dllud> IIRC I tried it several years ago, and it only worked with EFS v1. <@dllud> On my notes I have that: <@dllud> > OS builds from July the 1st 2013 carry EFS partition format v2 [...] <@GNUtoo> I've no idea what is the difference between EFS v1 and v2 and I didn't know there was a v1 or ve format [...] <@dllud> Ok, just read the thread. That method only works for EFSv1. Still nothing public for EFSv2. <@dllud> GNUtoo, the last post on that thread summarizes the difference pretty well: <@dllud> https://forum.xda-developers.com/showpost.php?p=63772220&postcount=135 <@dllud> There's also more info at: <@dllud> https://forum.xda-developers.com/galaxy-s3/help/i9300-network-unlock-firmware-version-4-t2612736

As a side note it would be great if there was an EFS v1 collection too.
