[Samsung Galaxy S Relay 4G] theZenman:
Hey guys. So, first of all, we've got our own forum! I don't know when it happened, as I wasn't really paying attention after the first few...months...but here we are!

Anyway, some of you may know about the free unlock method posted by owl74 in the Note II forum (link: http://xdaforums.com/showpost.php?p=34661189, has screenshots). This turned out to work for the SGSIII, the SGSII and SGSII Skyrocket. Well this post is to verify that IT WORKS FOR THE RELAY 4G TOO! :D

Before proceeding: do this at your own risk. There is no guarantee it will work for you. You MUST be running a stock ROM with a stock modem. I am using the UVMA2 stock ROM with the UVMA2 modem on T-Mobile USA.

Read ALL directions first before trying this out.

This was ONLY tested on MY phone, with the UVMA2 update and modem, on T-Mobile USA.

Without further ado, here are the complete steps toward unlocking the Relay 4G (Thanks again to OP owl47):

*NOTE:* Never use the "back" button. There is an option when pressing the menu button to go back.

First, dial

*#197328640#

in the dialer app

Hit option [1] UMTS

Hit option [1] DEBUG SCREEN

Hit option [8] PHONE CONTROL

Hit option [6] NETWORK LOCK

Hit option [3] PERSO SHA256 OFF

WAIT exactly 30 seconds.

Hit the menu button and select the "Back" option.

Hit option [4] NW LOCK NV DATA INITIALLIZ

WAIT exactly 60 seconds

There will be no prompt, but reboot your phone. It should now be unlocked.

Verify that your phone is unlocked by using a SIM card from another network. I tested it using my wife's AT&T SIM card and it connected successfully.

The prompts and the menu for the Relay 4G is a bit different from the other phones, but the screenshots provided in the original link above should serve as a rough guide for what you might see. I personally never saw the 'PERSO_NV_INIT is SUCCESSFUL' prompt, but it still worked for me.

Your mileage may vary. If someone is brave enough to give it a try on earlier versions of stock ROMs, be my guest.

For a rooted UVMA2 rom, gee one posted a link to his FTP site where he is hosting a copy of the rooted rom (should be CWM flashable):

Check nocturin's portal thread. Tons of stuff there, including this
[Samsung Galaxy S Relay 4G] theZenman:
Whoops, you're right. I searched the forums and couldn't find anything about "unlocking" that wasn't talking about screen unlocking.

I guess this is what happens when you go for months without an organized forum and people are just cramming everything into mammoth threads...
[Samsung Galaxy S Relay 4G] _RaZziel_:
Hi erveryone,

I am thinking about buying the Galaxy Relay, since my old phone broke, but because I live in Europe I'd have to import it. Is there any way (I could not find any using the search function) to SIM-unlock this phone without being on a t-mobile network?
[Samsung Galaxy S Relay 4G] theZenman:
As far as I know, sure. I had an AT&T SIM in there while I was unlocking it. After I rebooted, it connected to the network. I don't think you need to start connected to the T-Mobile network or anything.
[Samsung Galaxy S Relay 4G] raphaelcno:
When you follow the above procedure you don't need to have a SIM card in the phone, you are not on T-Mobile or any other network.

I also imported my phone and unlocked it in Norway, it worked nice.
[Samsung Galaxy S Relay 4G] kilr00y:
i bought an unlock code from an us site. seemed to be the easiest and fastest way to me.

never needed another simcard for the procedure than my T-Mobile Germany. And yes, it's specifically locked to T-Mobile USA.

A TM simcard from another country just gets rejected like any other provider's card.
[Samsung Galaxy S Relay 4G] dillalade:
This is a very handy tip for sim unlock.

I bought the phone for my cousin as he was jealous of my Relay.

Forgot about the unlock needed as neither of us or on Tmobile here in London. Happily saw this thread. 1, 2, 3 job done, for freeeee.

Thank you for finding and sharing this procedure.

Unlocking on Jelly Bean

I wanted to ask if I updated the phone to the jelly bean version before I unlock then I tried to unlock the phone will it work?
[Samsung Galaxy S Relay 4G] Jax184:
I only tried unlocking before the upgrade. If you unlock before, it remains unlocked after the update. Don't know what happens if you try it after.

[Samsung Galaxy S Relay 4G] jarrodlombardo:
I'm on a stock rom and stock UVMA2 Baseband, but I am rooted. Should this work? If this fails and I have a backup in recovery, can I roll back to that or might it brick my phone such that I can't even get to recovery?
[Samsung Galaxy S Relay 4G] jarrodlombardo:
I tried it. It did not unlock my phone. It did not harm my phone in any way I can tell, it just didn't unlock it. I've called T-Mobile to request a sim unlock code from them.
[Samsung Galaxy S Relay 4G] treaty:
undo

Gonna post this here just because it may be useful to someone.

I tried this unlock method - but I tried it AFTER I had done the OTA update to Jelly Bean. It obviously didnt work. I then went to T-mo and got them to give me an official unlock code. The unlock codes they gave me would not work though - just kept saying "unlock unsuccessful" no matter how many unlock codes they gave me to try. I noticed it seemed like it wasn't even going out on the network to try to validate the unlock before saying it was unsuccessful... so I did the unlock backwards kinda:

in the dialer app

Hit option [1] UMTS

Hit option [1] DEBUG SCREEN

Hit option [8] PHONE CONTROL

Hit option [6] NETWORK LOCK

Hit option [3] PERSO SHA256 ON

WAIT exactly 30 seconds.

Hit the menu button and select the "Back" option.

reboot your phone.​

After I did that - I was able to get the unlock code from T-mo to actually go out and validate and unlock the phone.
[Samsung Galaxy S Relay 4G] reaper000:
I am unable to complete the instructions in the OP because the network lock menu on my Relay 4g does not have the 4th option... Only 3 options.

Failure to unlock...
[Samsung Galaxy S Relay 4G] gee one:
What version of the stock rom are you using? Maybe you have to flash back to a previous version.
[Samsung Galaxy S Relay 4G] reaper000:
Haven't begun to even play with it! Straight out of the box, not rooted, nothing. It is running 4.1.2, though. I was hoping to confirm it worked on Straight Talk before I really started to mess with roms and flashing stuff...
[Samsung Galaxy S Relay 4G] gee one:
4.1.2 is Jelly Bean. Maybe you have to flash back to Ice Cream Sammich. See the posts above about issues with Jelly Bean.

To flash back, I think you either need heimdall or a custom recovery (although I think you need heimdall to flash a new recovery).

Hey guys,

I just got my Relay 4G in the mail yesterday.... I was playing with it and without SIM just wifi enabled I did all the updates, then I found this thread... (oops)

I hitup www.samfirmware.com, I rolled back to UVMA2 update using Odin 3.07 (put the .tar.md5 file in PDA and flash)

Then I booted into recovery and did a factory wipe. I followed the directions in this thread, voila ... unlocked phone, it works now on my Virgin Mobile SIM card in Canada.

(Did this help you ??? There's a button for that ;0)
[Samsung Galaxy S Relay 4G] computerinfo21:
Succes on two phones here

Thanks for the instructions, worked perfectly!

I bought two used, one was already on Jelly Bean, and as noted above the option just is not in the menu as listed in directions. After flashing it back to the Ice Cream Sandwich stock rom I could proceed with the unlock and it worked perfectly. The other phone was ICS already and it unlocked first try. :good:
[Samsung Galaxy S Relay 4G] Pat MeGron:

Hey, I updated to Jbells too and I'm trying the method you just did.

ODIN keeps saying the md5 file has value is invalid.

Suggestions?
[Samsung Galaxy S Relay 4G] rudias:
Try downloading file again.
[Samsung Galaxy S Relay 4G] Pat MeGron:
Nope nothing, I'm using Odin 3.04 and the T699UVAMA2 item.
[Samsung Galaxy S Relay 4G] rudias:
I used Odin 3.07 yesterday and followed same method and it worked fine for me. If MD5 does not match, then it is most likely due to a corrupt download or something else interfering.
[Samsung Galaxy S Relay 4G] Pat MeGron:
Ok you may call me an idiot for this one.

I changed the file extension from .tar.md5 to just .md5 and the operation went through.

Ive been staring at the Samsung Logo for half an hour and nothing....soft brick correct?
[Samsung Galaxy S Relay 4G] rudias:
Shouldn't take any more than 5 minutes to boot up after showing Samsung logo so next time you can save yourself time. Good idea is to try downloading rom using any download manager so more likely to download correctly. MD5 check is there for a reason. Also if you successfully flash the rom and still gets stuck on Samsung logo, try going into recovery and doing a factory reset and hopefully it boots up. If it still doesn't then do a flash again and it should work.
[Samsung Galaxy S Relay 4G] Pat MeGron:
I shall keep this in mind, though this particular Relay of mine isn't rooted so I don't think I can go to recovery (CWM or TWRP).

Thanks for the replys too :)

Back to the purpose of doing this, if I won't be able to revert to ICS and will only be staying at JB would there be an alternative to unlocking the phone?

EDIT: The only, for the lack of knowledge of its name, firmware of the phone I was able to flash was T699UVBMC5_T699TMBBMC5_TMB which is already a JB. So im not sure what im doing wrong here.
[Samsung Galaxy S Relay 4G] rudias:
You don't need root, there is already a recovery installed. You just need to turn phone off then hold down, Volume Up key, Home key and Power key. Once something shows on screen you should release power button. Once you are in it, select the factory reset option (Volume keys for navigation and power button for selecting). This is once you have flashed to ICS which passes with valid MD5. If it still does not boot up flash again and do factory reset again and it should work.
[Samsung Galaxy S Relay 4G] Ziida:
Confirmed working on ICS (4.04) of stock ROM. Will report back if it stops working after upgrading!
[Samsung Galaxy S Relay 4G] theZenman:
I've since moved on to Cyanogenmod nightly and it's still unlocked!

T Mobiles New Unlock Policy

Say, hi there everyone. I want to buy a samsung relay but i just learned has recently changed their unlock policy to no unlock codes for 18 months after purchasing the phone.

My carrier is ATT. So am I making a big mistake? No more unlock codes from T Mobile?

thanks in advance
[Samsung Galaxy S Relay 4G] gee one:
PM sent

I think T-Mobile will unlock the phone for you once it is paid in full (equipment plan). You can unlock it for free on the older ICS rom, but I think the feature was removed from the Jellybean version.
[Samsung Galaxy S Relay 4G] JD421:
Well I will be purchasing it from ebay or amazon, so. But even T mobile customers are not able to get the unlock code unless 18 months has passed, even if they are going out of country with it, the answer is no you can't have it.

I tried to confirm this with some of the unlocking companies but their 24/7 support is unavailable.

This is a very new policy from T Mobile.

thank you for any comments.
[Samsung Galaxy S Relay 4G] RodimusConvoy:
Well my game plan is buy it, open the box, charge the phone, THEN do this unlock code before doing anything else (rooting, upgrading to Jelly Bean, etc). Plenty thanks. :good:
[Samsung Galaxy S Relay 4G] C3POID:
I tried my unlock code with an old SIM card on different CM10.2 nightlies but the code doesn't work.

Then I read about that I have to be back on the original rom. So I rebuilded my saved stock rom over nandroid CMW, did a restart and *tadaaa* the unlock code was working, yeah.

Now I can go back to CM10.2

just my 2 cents
[Samsung Galaxy S Relay 4G] JD421:
Got the phone, need advice

Hey guys, Newbie here...

I just got the S Relay in and as I suspected it is locked. So I had a chat session with T Mobile and this is what they said,

"Jeffrey S: This is what you can do, you need to but the Starter Sim Card kit from any T-Mobile Retails Store, activate the Sim Card and make sure you have a refill for a minimum of $50 for the next 40 days in order for us to request and unlock the phone."

So it is not a 18 month wait like I previously posted.

The phone has a bunch of stuff on it and phones logs and such. I would like to get rid of all of that.

Do I unlock the phone first or do a factory reset first or does it matter?

Then when I get that done, do I type exactly whats on the original post or is that for Samsung's other phones?

This phone is running 4.0.4 , the baseband version ends with uvma2 and the build no. ends with uvama2, i also have the imei no. if i need it. the phone was purchased over ebay.

Once it is unlocked, i will be putting a att sim card in it.

thanks so much
[Samsung Galaxy S Relay 4G] theZenman:
You don't need to do a factory reset first just to unlock it. As long as it's the stock ROM, you can just follow the instructions I put in the first post. (I based them on instructions for other Samsung phones, but changed whatever needed to change for this specific phone.)
[Samsung Galaxy S Relay 4G] JD421:
Oh thank you so much! I have never done this before. I am worried.
[Samsung Galaxy S Relay 4G] JD421:
OK I did it and it worked. I can now make calls with the Relay on my att network!!!

Only problem now is I can't get on the internet with it. I checked all the settings several times and I don't see what the problem is. So I took out the sim card, put it in my old phone and it went to the website.

so not sure what the problem is now. Any thoughts?
[Samsung Galaxy S Relay 4G] gee one:
I think you need to update the APN info in settings/mobile networks/access point names... (at least that is where the settings are in cm-10.2. I can't remember where they are on the stock ICS rom)

Google for AT&T APN and you should find something... you can probably also look on XDA in some of the other AT&T device forums.
[Samsung Galaxy S Relay 4G] RodimusConvoy:
Well I know on my Epic 4G, all I have to do is click on the Voice Dialer app and then say "APN". An "Open APN" option will show up (I forget the exact verbiage), I click on it, and voila. I've been able to do this since Gingerbread, and I just tested it on CM 10.1.3 and its the same. Chances are it will work here too.
[Samsung Galaxy S Relay 4G] JD421:
Thank you guys, I found the APN settings for AT & T and also added my old AT & T phone APN settings.

Its working OK now except for two things.

1 I can't send mms messages with pictures. So I need to find another APN setting that will work.

2 I do not have real 4G. I thought this phone was a 4G phone. Come to find out that T Mobile 4G is not the same as AT & T LTE. So I have about the same connection speed as my old samsung captivate. The only difference is a better keyboard and 5 gb space just for apps. The samsung captivate had 1.89 gb of space for apps with gingerbread installed. All that other space was wasted. You couldn't download apps to the "usb memory" and most apps generally can't be moved to the sd card. I moved some but I ran out of space quickly. And this was just utility type stuff for work, nothing for fun.

So after all this, I just can't believe I was duped into fake 4G. I thought I had done my homework thoroughly.

If anyone knows anything about APN settings, I am all ears.....

so disappointed...
[Samsung Galaxy S Relay 4G] AndyYan:
No luck trying this method on T699UVALJ1 (older stock ICS). The phone can't connect to my carrier's network.

EDIT: Even on T699UVAMA2, it still didn't work out. What's more, I'm starting to believe that my Relay 4G isn't locked at all from the very beginning - it didn't ask me for an unlock code when I plugged in my non-TMobile SIM card. Can someone guide me on what else kind of problem I might be having?

Problem: No '[4] NW LOCK NV Data INNITIALLIZ' option

I got a Relay off of Amazon and it even came with an unlock code! Unfortunatly, that code didn't work...

I tried this method, but there was no NW LOCK option no matter what I tried, and it wouldn't unlock.

The phone is the UVBMC5 model, and have with >4.0.1 installed.

Solution

Install CWM and flash the ICS rom AND the radio zip found here.

I tried just flashing just the ICS rom, but there still wasn't an NW LOCK option. It was only after I flashed the radio firmware as well did it show up.

It worked and unlocked fine after updating the radio firmware!
[Samsung Galaxy S Relay 4G] RodimusConvoy:
I was meaning to ask this, but I was unsure under which thread.

Say you just got the Relay 4G in the mail, the order of things is:

1) charge it (well duh :laugh: )

2) Flash CWM

3) Flash ICS rom

4) Flash the radio you just mentioned

5) Do the unlock code

So basically the unlock code should be done LAST? I'm also wondering if its okay to just go ahead and flash Cyanogenmod 11 instead of the ICS rom.
[Samsung Galaxy S Relay 4G] Magamo:
None of the community custom images work with this unlock code. Neither does the JellyBean Stock image. So you want to follow the unlock procedure before installing whatever else you wanted.
[Samsung Galaxy S Relay 4G] padalec:
HI,

Today I get my Galaxy S relay (t-mobile). The telephone is locked so I have to unlock it. I also want to root and install CyanogenMOD on it.

So my question is:

Can I directly root the phone (it will unlock by itself)'?

or

I need to unlock it first? Then Root

Thanks
[Samsung Galaxy S Relay 4G] Magamo:
There is a difference between being bootloader locked, and being SIM locked. This thread deals with being SIM locked. SIM unlocking can only be done on one specific revision of the Ice Cream Sandwich Image that Samsung released for this phone. The Relay does not have a locked bootloader, so you can root it directly.
[Samsung Galaxy S Relay 4G] RodimusConvoy:
So basically, as soon as someone gets the Relay 4G, this should be the very first thing they do (if they're not on T-Mobile) before they do anything else?
[Samsung Galaxy S Relay 4G] Magamo:
This can be done after installing a custom recovery, and rooting. But must be done on the listed Touchwiz image, with (I believe) the corresponding modem, and since every custom image that has been released after the CyanogenMod 9 alphas has required the modem and bootloaders from the Touchwiz Jelly Bean release, it's probably advisable to unlock before moving on. However, there is nothing stopping someone from flashing the appropriate images afterward, and unlocking later.
[Samsung Galaxy S Relay 4G] RodimusConvoy:
Thanks for your patience. This thread pops up seemingly bi-monthly and I keep forgetting I already responded in it.

I went back and read through it a few times. The way I understand it, this unlock code works only with the UVMA2 rom and UVMA2 modem, because using the code with that rom and modem will bring up extra menu options to unlock the phone. Any other rom / modem, the code will bring up the menu, but the extra options will be missing and thus unlocking via this method will be impossible. Unlocking can be done on any rom via third party companies, but not for free. To use this method, the free method, it must be on this rom and modem, UVMA2. Hence why if it isn't already on UVMA2, it must be flashed to it, meaning yes root and recovery must be installed first to put it on the UVMA2 rom and modem.

Am I on the right track?
[Samsung Galaxy S Relay 4G] Magamo:
Sounds like you are.
[Samsung Galaxy S Relay 4G] cybertim:
Second time i'm using this and it worked again!

I use Odin to flash 'T699UVAMA2_T699TMBAMA2_T699UVAMA2_HOME.tar' to the phone (before doing anything) and follow the steps here.

After that I flash CM11, root etc.

Both my Relay's are working fine now with my Dutch operators :)

Thanks!
[Samsung Galaxy S Relay 4G] Suncatcher16:
Great job, guys!

I've strictly followed the instruction and was succeeded:D

Thanks for help! God bless America!:cowboy:
[Samsung Galaxy S Relay 4G] seidler2547:
Ok, here's another way: I bought a second Relay 4G on eBay, it had stock Jelly Bean ROM and a newer radio.

I was lazy, so I flashed ONLY the UVMA2 radio through TWRP (I wanted to use ODIN but I could only find a zip for CWM/TWRP), the instructions then worked fine on the 4.1 stock ROM with the older radio. Then I flashed OmniToad and the most recent radio and everything continued to work great.

I got a Galaxy Relay 4G with T699UVLH1 firmware (this appears the original Ice-cream Sandwich version of Android that came with the phone). I plugged in a Lycamobile sim and verify that it was locked to Tmobile when it prompted me for a SIM unlocked pin. I then follow the procedure to unlock and was able to unlock it successfully. When I plug in the SIM. it now allows me to make calls.

No
[Samsung Galaxy S Relay 4G] paul.siu:
So I unlock the phone using the method, which worked. I then updated the ROMS twice, once to the next version of ICS and then to the final version of stock Jelly Bean 4.1.2. All this time, the unolock remain in place. I then rooted using trowelroot and the phone is still unlocked.

Bought a new-in-box T-mo Relay S 4G, it had 4.04/ICS on it. NOT activated/no Sim installed. Connected to my home Wi-Fi network (did Not enable Wi-Fi calling), and entered the code in dialer ... it immediately started downloading an update (which turned out to be JB/4.1.2), I had expected a terminal so I could select options. After a full reboot of phone and operating w/ JB, tried again, now I get the menu's but never get the 4th option in step 9 after the 30 second wait, any suggestions?
