Mostly I did this because of people who may have problems with Kies Mini to update to UVKD1 (like I did, took forever to get drivers etc and kies to behave).
Again this is completely stock! Nothing done to it. I did use Kies Mini to apply this update automatically, but again it's the unencrypted zip that gets flashed to your phone.
As always, I'm not responsible for bricking your device etc. etc.
I imagine this can be used via ODIN to update your device, but again I haven't gone through this process.
As I have not tested this method personally, I cannot guarantee anything. Just wanted to provide the STOCK Zip without the encryption on it.
Anyone more knowledgeable about this please feel free to interject.
