Note this may not work for everyone. Please follow the thread listed above for more information.

[@larryfisher9260]

Thanks tons for this. I had called att, got my unlock code, and tried that and it didnt work. Using this tutorial worked perfectly and I am DONE with att forever!

[@LubertRodrigues]

This worked for me but have to follow +AtechHD comments. "That people cant do it i have found a new way to do it do *#0011# them do back and do key input do Q pess ok and pess input and put 0000 and that will work for you." Also if you dont see your option in Network locked, just follow rest of instructions. it works. after restarting phone by it self, pull your battery & restart phone again before using.

[@sssesoj]

+Lubert Rodrigues Thanks for that :)

[@hohohoha475]

Not working....When I dial *#0011#. It appears but when I select key input and put 1. It's not working. Nothing change. I don't know what happen to my phone. Please help me. Tnx..

[@justinyarleque7218]

i type 1 into the key input and it goes back to the menu that it was at before.... not the one that it brings you to... why...

[@danpineda4447]

same here

[@adriancatian6396]

Type Q1

[@osse0005]

Worked again thanks for creating a quality video! (AT&T S4 MDL)

[@lancetyree398]

I have a S4 from AT&T and I am trying to use my T-Mobile sim card. When I got to the key input then put 1 and ok, it does nothing. How do I get it to work?

[@Unlockunitcom]

Lance Tyree If your phone does not ask for the unlock code and it only says “Network Locked” then, as if making a call, dial: #7465625*638*#. Once prompted for code enter the unlock code and your phone will be unlocked.

[@infodrumm]

***** what is the key?

[@daronlapping4590]

UnlockUnit what's the key?

[@basetechsbasetechs2966]

Thank you for giving me the good tip, now my phone works perfectly, BASETECHS did it correctly.

[@AtecHD]

That people cant do it i have found a new way to do it do *#0011# them do back and do key input do Q pess ok and pess input and put 0000 and that will work for you

[@LubertRodrigues]

AtecHD Thanks leaving note in comment, your instructions worked for me.

[@AtecHD]

[@fantomlord9550]

AtecHD Just got my s5 unlocked completely for free from samsunggeeks .us !!

[@AtecHD]

Did my way work or did you use the video way

[@glynnkev]

AtecHD this finally got me into the menus they reference, but I still have an issue: the PERSO SHA256 OFF option does not show up. All I see is PERSO SHA256 Info and RAT_FREE_SUPPORTING ON

[@EvanMcCarter]

This is interesting, but considering that my contract is probably over 2 years old, I'll try calling AT&T first Thanks for all the info though!

[@colethemolester]

I'm having the same issue where it stays on the same screen after the "key input 1" screen :( anybody know why?

[@tbjoshuamyprophet6531]

[@julioosilia]

[@DezertRoze17]

I got as far as where you need to input the value 1 then it did not go to the UMTS Menu, and now it says that there is NO Sim card.

[@rashaneallen1574]

[@anishnaidu5917]

[@backasswards5250]

So get to point; "enter value, 1, press ok" after going back into menu, press back. I never get to "servicemode" screen.. SGH-I337.

[@cezarymalinowski1730]

Not working on ATT phones... Even yor post on XDA was remove...

[@Laurajuniejr]

I'm stuck at inputting the "1" value. Goes back to the service mode. BUT for a split second after inputting "1", there's a screen that pops up reading "menu not exist, press back key, command is 1111" I barely could read it out cause it pops up real quick. Any suggestions.

[@mayurpatel815]

If there is no back up what to do

[@ChristmasDiamond]

This is probably going to be a stupid question but I have to ask it. So if you unlock the SIM's network, is that like having an unlocked phone basically? Or is it better to just have an unlocked phone? I all ready have an unlocked S4. I am just asking.

[@loganames656]

...

[@ChristmasDiamond]

Logan Ames That does not answer the question, sweetie. And my phone is all ready unlocked.

[@midnitemedia]

Chrissy S SIM unlocking your locked phone makes it the same as a factory unlocked phone.

[@ChristmasDiamond]

True Story Ah! Okay. Thank you.

[@ChristmasDiamond]

vashtheazn please stop board casting the sites you use. Your comment will be removed.

What sbout version 4.4.4?

[@glynnkev]

Yeah, is there a way to do this on 4.4.4? I get stuck after PHONE CONTROL --> NETWORK LOCK --> ? At this point the only options are PERSHO_256 Info or RAT_FREE_SUPPORT ON or something like that. If I click PERSHO_256 Info I then see SHA_256_ENABLE FLAG [1] any advice? I'm new in android, just starting to learn, so I'd love some help. Thanks!

[@52hoova33]

+Kevin Glynn me too im stucc on that point

[@glynnkev]

I think the only way is to downgrade to 4.4.2 (correct version?), perform the steps above, then perhaps upgrade back to current version.

[@Hi.Im.Chucky]

+Kevin Glynn Then how do you downgrade?

[@glynnkev]

Google it. Plenty of tutorials out there.
