Unfortunately, I think you will need to unlock it every time after you do a factory reset. (unless someone comes out with a new rom, but I have not seen any development for the scl23; at least not that I know of)

Dial *#9090# dialer ( try *#0011# if *#9090# wont work)
Tap 3 dot on top right, Type "Q" (case sensitive) => Tap OK => Type "0000" => Tap OK
Then wait, if u tap anything else, those step above wont work and you'll need to do it again.

Done.

Unlock any SCL23 even @ 5.0

Hey guys, I've been following every unlocking threads for the SCL23 but no one seems to have the answer how to unlock ALL VERSIONS of SCL23.

I actually had mine for a year now and just decided to unlock it now, I have it on Andoid 5.0 which if you may know *#*# codes doesnt work anymore.
If you do some research, you also can't unlock SCL23 with Baseband ending with BNG3. Even if you're able to do the *#*#9090# code and followed the unlock procedure, it will not work!

Work around is:
1. Downgrade with ODIN to Android 4.X firmware version BNJ1 for SCL23.
2. Do the *#*#9090# Hack. Try *#*#0011# if you 9090 doesnt work.
3. Upgrade to latest firmware via ODIN
4. Profit

P.S.
I downloaded SCL23 Android 5.0 via SAMFIRM
and SCL23 BNJ1 from android firmware websites.

Hope this helps coz i tried going to different websites like vietnam ones! Most of the guides to unlock SCL23 are in Japanese so here's the source for one: http://mobilersidea.blog.fc2.com/blog-entry-45.html
