Update I've tested on Galaxy note 4 with 5.0.2 and is compatible and has more option because you can select more then one band for example you can choose only GMS900 and WCDMA900.
As soon as possible I will upload an updated video.

Thanks to this great video, I managed not to have to get rid of my S4 mini GT-I9195.
After more than a year messing with the phone and even after having changed any parts. I found that was not damaged, if not in the service menu was misconfigured. Or 3G or 4G is not connected, it was configured as shown in the video and only connected EDGE. After putting it on automatic, and I have 3G and 4G!
Thanks, I owe you one.
P.S. How is it possible that the phone came with this misconfiguration my hands, if you buy in Phone House Spain. Attention, buy pre-owned.

omg dude tyvm for showing me how to open that service mode because of it i managed to fix no service on my s4 mini!!!

This is really useful but the menu has changed on the Galaxy S6 and the Q and 0000 no longer does anything. Any idea what the new code is?

[Reddiitstories]

In my I never see the youtuber who's phone is 100% charge..

This procedure worked fine when I downgraded my s5 to 4.2.2, but, can"t find the options when upgraded to 5.0. I'm using SCL23, an S5 variant of AU(KDDI), Japan.

I have a brand new Samsung Galaxy S5 and I want to select a given band. I just tried this sequence, but after I got to the key input 0000 nothing happened, even after I waited 5 minutes nothing came up. Any suggestions on how to get to band locking to work? *#2263# did not work either.
