Hmmm... We have confirmed successful unlocking reports from Philippines, Hungary and UK users. I don't know why you can't unlock yours. So far only the I9505 have been tested. Bytheway, mine has a MDM Version. Whats yours?

To those who successfully unlocked their i9505 using this method, what rom version are you on?

I had to go in and search for networks. Its ok now.

Nekem azt írja a végén hogy nincs elérhető back-up verzió. Mi lehet a gond? T-mobile-os i9505. Üdv, Joe

---------- Post added at 02:37 PM ---------- Previous post was at 02:26 PM ----------

I'm from Hungary, the i9505 from T-Mobile and need to unlock. Followed the instructions but got this at the end:

"Back-up not exist [First you must make Back-up by using [3]menu]"

I create a post in spanish forum some days ago about unlock i9505.

Some user reports work well, but some users reports not work.

The thread is:

http://www.htcmania.com/showthread.php?t=607799

I have an orange locked i9505 and unlock only with sha256_enable_off. Not needed to use NV Rebuild.

But some vodafone users can't unlock his phones. They try all steps, include NV Rebuild/Restore Backup and NV Rebuild/Load default NV, but phone still locked. They are on I9505XXUAMDN...

I don't know what is the problem...
[Galaxy S 4 General] nek_nek:
Hello. But after the last step, I get an error. It only flashes for less than a second and says "Error" at the top. After that, I get the blue led light on, menu and back keys are also lit up then my phone reboots. But it is still locked after rebooting. I have tried the steps numerous times, but still no luck. Hope you can help me.

What part of the phone affects the samsung secret menu?

Because if its the rom, anyone could just flash whichever rom allows for the unlocking, unlock and then just flash whatever back.

Call it method 3 if you want.
[Galaxy S 4 General] lawbo:
I think it is just need to flash other radio. I can't verify that because the bootloader is still locked on att S4.

When I have ATT skyrocket, I wasn't able to see some secret menu until I flashed T-mobile radio. After I unlocked, I flashed back to ATT radio.

Hi all i did sort of fix mine i got it to work with my sim and i got texts comeing to the phone but could not send them or make calls i think at the end the ime got messed up got my new one now but i think i will pass on this lol i think some phone's will brick like mine has the first time i did as in the gide but it briked i would just be carefull
[Galaxy S 4 General] ZiDanRO:
This a very dangerous mode to unlock your phone.

You can loose your imei or the phone calibration witch is stored in nv_data.

For a few bucks for a correct unlocking you risk to damage the phone.

You are advised so easy to restore your default nv_data, but they don't know that this will destroy your phone calibration

I see lots of successful unlocking, but on the long term nobody say that they have drops on the time of the call. Or that they can't receive calls.

So this is a nice discovery, but this is not the right way to do it.
[Galaxy S 4 General] s4lah:

[Galaxy S 4 General] caskas:
Example:

If my phone as any kind of problem and I need to take him to store and go to waranty, they in technical assistance test to see if it´s unlucked or not, if he is unlock and I dont have the ticket to show that it was a "Official Unlock" I´ll lose waranty.

that´s why:\
[Galaxy S 4 General] lordcheeto03:
I am so glad that I took the time to read through 2 or 3 of these threads front to back; I would have completely missed this absolutely helpful post! I had accidentally deleted my original NV backup on my 3rd or 4th failed attempt at unlocking so I gave up with this method and bought an unlock code. After that code failed as well, I decided to just keep reading. It wasn't long until I came across this post and tried it. After restoring that setting, I rebooted and input the code I bought, and I'm now using my AT&T SIM card in the T-Mobile variant!

Anyone who can help me how to unlock my S4

Hey Dudes !

I ' m from Austria and finally I got my S4 with Simlock to Mobilkom Austria. First I tried all the steps in the tut above I think about 100 times nothing worked. Even when i finished last step theres a short messages error it reboots blue led is on but its not unlocked. I ordered an unlock code from cellunlockers.net NETWORK=81528491 PROVIDER=35056963 SUBPROVIDER=63250187 DEFREEZE=59293936 but when I insert it theres an error network unlock request unsuccessful. I guess its the wrong unlock code so I ordered it from another shop and got the same :) about 40 Euro for nothing hope I'll get it back

Has anyone an idea ?? Rooting the phone is no problem

[Galaxy S 4 General] croach246:

When i go into phone control the screen says menu does not exist and "current command is 186"

[Galaxy S 4 General] aligatorx:
3. method (implies payment of $25 at cellunlocker.net)

If you already tried the two methods without results, you could have disrupted adjustments in SERVICE SETTINGS.

Assuming that you already bought unlock code, you will have to return value SHA256 to ON:

*

*

NETWORK LOCK

SHA256 info (Back)

SHA256 ON (Back)

once again SHA256 ON (you must go twice on this to switch SHA256 to ON)

*

Back all the way to the COMMON

*

NV REBUILD

MAKE BACKUP (Back)

RESTORE BACKUP

Your phone will restart and ask you for UNLOCKING CODE. Give in the code you bought and your SGS4 is unlocked.

This is how I've done it and it worked. I tried installing another ROM, the phone is still SIM UNLOCKED.

Credits to chavxxx. Good luck!
[Galaxy S 4 General] croach246:
Indeed, you can buy the code for 25$. Im just puzzled why my service settings were different to all the guides ive read.. And as you said, installing a stock rom (i9500UBUAMDE) will NOT unlock???

Thanks very much to the peeps who dedicate themselves to others.

Its all good guys,

Thanks.

[Galaxy S 4 General] adicumi:
Hi guys,

I'm new here..

and I just want to tell you that I just unlocked my SC-04E (Galaxy S4 Docomo version) :D I use the first method and working directly

thanks for the guide, it really helps a lot..

P.S. I was scared at first, as after the first reboot I can't use my docomo sim, it shows error in connecting to network. but when I try using another sim card (non-docomo sim), the phone can detect the network successfully.. then I changed to docomo sim again, I need to search network manually first before it can detect and connect to network.. the next reboot working without any problem :D
[Galaxy S 4 General] Ekimalito:
It works!

So... I had bought the unlock code from 2 different people on eBay... they were exactly the same and they didn't work. I figured I could've messed a couple things by playing with my phone trying to unlock it for free. Followed the steps here and turned the Perso Sha256 option back to on, restarted the phone and tried the code again. After that it was accepted and my phone is now OK... so yeah, it works

MANY THANKS!

Hey, I sort of half-completed the steps, and backed out where it said "3]PERSO SHA256 OFF". I think I did tap it. I backed out cause I figured that even if the risk was small then it really wasnt worth anything going wrong.

Could I have made any change to my phone even though I did not complete the entire process? I feel that my wifi is slower... but perhaps that is just me being paranoid!
[Galaxy S 4 General] borikat:

Didn't work on my Rogers either.

If you go to purchase an unlock code (cellunlockerpro was $16) and it doesn't work. You have to go through these steps again and in the step that says "then tap [3]PERSO SHA256 OFF" reverse it by tapping [2]PERSO SHA256 ON" back out and reboot.
