As for galaxy note 2 (gt-n7100) and sgs3 (gt-i9300), Samsung changed the location of the lock state in their latest updates of gt-i9500. As of now, I couldn't find where it has been moved. I'll update gsu when I have more information about it.

Pm me if you want to test something with me.
[Galaxy S 4 General] iakovl:
its the MG9 i think...

when i press the 1 in the service menu it says it's in input mode 111 ? did i input 111 instead of 1 and made it stuck?

went to a lab today, they used NSpro and Z3x, both "unlocked" the phone... still asks for pin code
[Galaxy S 4 General] ivan84gt:
Is there a way to undo this unlocking?

I tried it on my verizon S4 and now i can use it on verizon any more. When I rebooted it looked like it connected to network and data works but cannot make calls. Says network not available. A roaming triangle show on top of the network bars.

Doesn't work on my Claro Panama i9500 either, can't even get to the service menu.

Galaxy SIM Unlock from the Play Store doesn't work either, says no code available.

[Galaxy S 4 General] jh787:
What rom did you use when you actually unlocked?

mine is locked to 3 uk and i have tried both the op method and the edited version but it is still locked.

I flashed the generic btu rom on as soon as i got it so i am thinking there is something in the 3 official rom that is needed to get this to work??

I am downloading the 3 official rom as i type and i will post any results. Rom version is xxuamdf
[Galaxy S 4 General] habz1234:
i JUST now done this exact procedure, rather the second one which was labelled by a poster.

my phone was locked to Three (i9505), it has worked, all steps from second guide were followed successfully. Ive put an EE simcard in and it seems to be working, however when i make a call the number comes up as unknown and doesnt allow me to send messages :S

anyone else having the same problem?

thanks
[Galaxy S 4 General] evilive27:

I am on ME2 the pre-rooted one from djemby. I9505XXUAME2-DEODEXED-KNOX-FREE-HD-VOICE

I was not on the official Three ROM. I9505XXUAMDC_I9505H3GAMD6_I9505XXUAMDC_HOME

---------- Post added at 06:45 AM ---------- Previous post was at 06:12 AM ----------

Ok, for those wondering if this is a permanent unlock.

I had sim unlocked my phone when I was on the "djemby" pre-rooted I9505XXUAME2-DEODEXED-KNOX-FREE-HD-VOICE

I have just re-flashed my

original factory

Three ROM. I9505XXUAMDC_I9505H3GAMD6_I9505XXUAMDC_HOME and the Sim unlock was still

UNLOCKED!

I then re-flashed back to I9505XXUAME2-DEODEXED-KNOX-FREE-HD-VOICE.tar.md5 and the sim unlock was still

UNLOCKED!

So, I think we can safely say this sim unlock method is a permanent unlock! :good::laugh:

For people struggling, read the OP again, try that method. If that does not work, try my method, which is very slightly different.
[Galaxy S 4 General] DevilS4:
Just to mention I also done it on my mates S4 UK on Three with the most upto date software on. Plus I hit end just after I clicked perso unlock thing... and followed the steps again and it still worked.

well i am not desperate but gave that 3 try didnt work for me. im on three-uk with mdm firmware, got stuck at boot screen couple of times but removed the battery and restated. i saw couple of guys with three sim got their phone unlocked are you sure guys your phones weren't locked to three cause whoever got their phone on the 26th should have a unlocked phone from three i dont know why but i have two phones from three one i received on 26th unlocked and other 10th was locked. few people were saying on three sent their first batch unlocked.

hi just to confirm i have the i9505 with 3uk firmware also was locked on 3uk did the edited version and it worked for me tried a giffgaff and orange sim all workes fine
[Galaxy S 4 General] DevilS4:
I Can assure you mine was locked as I tried the sim before hand I got mine on 1st May and I pre ordered it on the 11th and the sim didnt work!

My mates S4 has a different kernel to me as well... plus he has more bloatware...
[Galaxy S 4 General] artnada:
If you put a different carrier sim in and it asks for a "sim unlock pin"...you can bet your bottom dollar it's locked :p

I have had 2 S4's from Three.

The first one, received on 26th April via online www.three.co.uk site, came unlocked and unbranded.

The 2nd phone, received one week later, ordered via phone sales to Three, was locked and branded to Three.

It is the 2nd one I unlocked yesterday.

[Galaxy S 4 General] DumblePaw:
Guys, I misunderstand that my phone is lock because I've not set the APN after flash new ROM. So, I followed the step with an unauthorize SIM and now the sim is locked :( and I can't find an authorized SIM coz I'm in Thailand.

How can I unlock the SIM again?

Please help me. Thanks in advance.
[Galaxy S 4 General] bonta_kun:
To those who uses Rogers, they've patched up the service hole with the recent patch. I had the same problem until I came across a post saying using ODIN and flash to the earlier build. If you search up ODIN flash s4 and refer to galaxy s4 builds. Build Date: 22.04.2013 -> Region: RWC (Canada (Rogers)) is the one I used and the original method worked like a charm. Just need none Roger/fido sim to test out now. REMEMBER TO BACK UP YOUR PHONE AND DATA! Cheers! :o

[Galaxy S 4 General] chubby65:
Looks like your screwed mate i think your on the new bootloader because you flashed stock MH5 rom
[Galaxy S 4 General] liquidspace:
It was originally on MH8 (T-Mobile Brand)...so, no chance - only by buying a network unlock code?

Hi there I'm on Three UK, was on MEA, however I flashed modem to ME2 didn't work, and my three bootup sign doesn't come on when I turn the phone on. Can you help getting the phone back to original stock modem with the three bootup.

I type in google the 3uk modem flash can't find it gives the same baseband suggested in samfirware but says it belongs to different country such as Switzerland. I have tried downloading from samfirmware few times but downloads keeps stopping.

Thanks.

Still having issues with my O2UK S4 i9505.

It was on ROM XXUBMF8 / Modem XXUBMF8 and Icouldn't get to the UMTS menu.

Changed to modem XXUAME2 and also tried the older XXUAMDC, both allowed me into the service mode :). However....

In [NETWORK LOCK] menu clicking on [[1] PERSO SHA256 Info] returns

SHA256_ENABLE_FLAG[1]

going back and clicking on [[3]PERSO SHA256 OFF] also returns

SHA256_ENABLE_FLAG[1]

going back and selecting [[3]PERSO SHA256 OFF] a second time returns

SHA256_ENABLE_FLAG[0]

SHA256_Off => Not Change

Has anyone an idea why I have to do it twice to get SHA256_ENABLE_FLAG[0]?

Going to [NV RESTORE] at this point reboots as expected, but still have network lock afterwards.

I've also tried this with native O2UK sim inserted, and with another non-O2UK sim.

I'm close to spending money on a code at this point!
[Galaxy S 4 General] Chris334:
Just curious.

I have an i9505g (Google edition) that shipped carrier unlocked. My carrier is T-mobile. SHA256 info shows SHA256_ENABLE_FLAG[1]. Does inserting the carrier SIM automatically change this value to 1? Unfortunately I did not check this value before signing up with T-mobile. All they did was insert the microSIM - I was watching them the whole time.
[Galaxy S 4 General] jimbobmcginty:
My locked i9505 has a non-native carrier SIM and I have SHA256_ENABLE_FLAG[1] after bootup.

Same with native SIM.

just purchased a locked uk ee s4. im on MG7 version problem is its not allowing me to access the service menu!

any help?
[Galaxy S 4 General] chubby65:
See post above yours mate
[Galaxy S 4 General] jimbobmcginty:
Not too long since last post I know, but I gave up and bought a code for £7.99 off ebay.

Thing is, and I reckon this might be a big hint to others who have been unable to get the network lock removed, the network lock wasn't the problem.

The code suppliers send you several codes for different purposes, but the important two for this discussion are network unlock, and unfreeze unlock.

The network lock was rejected by the phone, with SHA256_ENABLE_FLAG[1] set.

However the unfreeze unlock was accepted, and the phone connected to the network straight away without reboot or airplane mode.

So might it be that some of the S4s putting up a fight are already unlocked, but need unfreezing. I'm not entirely sure what that is, haven't read the threads yet, but maybe that's useful to someone.

For your information my S4 was on O2 UK, ROM/baseband XXUAME2 .
[Galaxy S 4 General] gallous_boy:
doesn't work on mine. download and installed ME2 modem. followed the instructions but when phone reboots its still network locked.

tried with a ee and a o2 sim.
[Galaxy S 4 General] chubby65:
In that case mate your only other option is to buy an unlock code

Is there a solution to the "error" before rebooting when unlocking? Did and followed the unlock instructions carefully but upon reboot my phone still asks for the unlock pin. And yes i tried numerous times already.

sim unlock galaxy s4 L720 from Sprint to use Tmobile issues

Could anybody tell me whether or not I can do this method without the original sim? I only have my tmobile micro sim (phone was sold to me locked). I got the method steps down but Service Mode just reads "No Service" and I see no options to select. Am I supposed to insert MY sim before doing these steps? I cant afford to mess up. suggestions greatly appreciated.....

Can i unlock my phone anymore?

Just create new backup mate

Hi,

I would be interested if this works on the mini as well.

Did anybody have the balls to try it yet?:)

Thanks
[Galaxy S 4 General] aresbv2000:
I understand that I can make a new one....but as I see the "Golden Backup" is used to SIM unlock the phone(as described in this tutorial).If I restore the backup made by me...it will still unlock the phone?
[Galaxy S 4 General] GeorgeM269:
probably not. Too bad i cant do this with my i9500.
[Galaxy S 4 General] chubby65:
Whether or not you still need a backup mate
[Galaxy S 4 General] aresbv2000:
My phone runs perfectly without any "Golden Backup".

More precisely...what does this "Golden Backup" means?What is it`s purpose?

Thank you for your reply!

Have a nice day mate.
[Galaxy S 4 General] ladyhaly:
I believe it's made in the middle of the procedure, and that the Golden backup will be accessed by the Service Menu in Debug Mode to actually execute a script that will unlock the phone. Not at all sure about this, but that's what my general understanding of it is.

I am not sure how to resolve his issue with deleting his golden back up other than making another one, as one person suggested.
[Galaxy S 4 General] aresbv2000:
I will try to make a new golden backup when I`m gonna be on a stock ROM.And after that, try to unlock it.If it will work....great...if no...s#@it happens:))

I will pay for an unlock code if I`ll ever need to use my phone on another career than Orange.

Thanks for your reply!
[Galaxy S 4 General] spocky12:
Hi guys,

Unless your rom is too recent (Samsung changed the way they lock gt-i9500 on recent roms, I'm working on it), your devices should be supported by GalaxSim Unlock.
[Galaxy S 4 General] ladyhaly:
Here's a link just in case someone is looking for it. :)

Wish they supported my GT-I9505. Ah well. I gave up and bought an unlock code with one of those unlocking sites. Now thinking of finding out how to flash the unbranded original ROM on mine. My carrier removed a wallpaper and a ringtone and changed it to a logo and tune of their company's. All hardware, modem, phone, CSC, are same as unbranded so it's just a matter of network lock and their minor tinkering of the stock ROM. No carrier bloatware, thank God.

Galaxy S4 unlocking problem

Hi everybody,

I have just joined in.

I have recently bought galaxy s4 GT-i9505 T-mobile with the following information

Android version: 4.2.2

Baseband version: I9505XXUDMH9

Kernel version: 3.4.0-1220396

Build number: JDQ39.I9505XXUDMH9

Now, I've been trying to unlock the phone. I've done the rooting already and double checked it with Root Checker.

I've already tried you suggested method which suggests dialing *#0011# but didn't work for me. When I looked up the reason, i found out that my modem should be ME2, so I'm guessin my baseband should be downgraded somehow. Is this correct? Is there a different method to overcome such problem!? or let me just put it this way. How can I unlock my phone!?

I'd very thankful and appreciative if someone could help me

Thank you in advance :)

[Galaxy S 4 General] Kastebo:
Service mode stopped working

I have loaded ME2 via odin to my phone and I got into service mode and started to follow the instructions.

But I accidently pressed end in menu in the middle and now I cant access the menu. I get the service mode screen when pressing *#0011# but now nothing happens when I press back.

I have tried reapplying ME2 but no change. Any tips of how to get back in the menu?
[Galaxy S 4 General] ladyhaly:
Your modem should be... So yes, believe so. But the only way to do it is to root, I believe. So you've done the first step. You have Odin, yes? It's a free Windows application from the developer Chainfire for our flashing needs. There is a modem thread here, which lists regions, their current modem, and what modem they should downgrade to. You can see from the first two letters (XX, DX), etc. The thread title had the words "Galaxy S4 Modem's Collection". Oh, and yes, there is an apostrophe. Not a grammar boo boo, there is one with the thread title. I remember.

I believe after you've downgraded to the ME5 modem, you can do the procedure in the front page, have your network unlocked, and then upgrade again to the newer modem if you like.

You mean you can't access the Debug menu now? Were you able to before?

He said PM him. Do tell us what happens if you go ahead and accept his offer! :)
[Galaxy S 4 General] Kastebo:
Debug menu? I was abel to access service mode menu by dialing *#0011# and there pressing "BACK". But after pressing "END" instead of "BACK" in one of the steps in the guide i can now not access the menu.

Now if i dial *#0011# i get service mode but nothing happends when i press "BACK" so i can't get into the service mode menu.

Expert Opinion

Hi Guys,

ok, so, I'm looking for an expert opinion with this dilemma.

I have a GT-I9505 S4 with the following information:

Android version: 4.2.2

Baseband version: I9505XXUDMH9

Kernel version: 3.4.0-1220396

Build number: JDQ39.I9505XXUDMH9

I have rooted the device using ODIN and I double checked it with "Root Checker". From my humble expertise, since i was to root the device means that KNOX feature is not incorporated in my device, right!?

Now, for the last few days, I have been looking for a method to unlock the device. I have tried the #*0011# method without any use in addition to a couple more. Lastly, I have come across to the following method:

First Flash This Firmware : I9505XXUAMDM_I9505OXAAMDM_DBT.zip

1 . Turn Off Phone.

2. Hold volume down, home & power , Then volume up for download mode.

3. Connect to PC.

Use Odin 3.07 for flashing :

1. Select the extracted firmware in PDA Section.

2. Click start button, wait just a few minutes.

After flashing Unlock the phone :

1. Open Latest Samsung Tool 15.3.

2. Select model - I9505

3. Select COM PORT in PORT Setting.

4. Press *#7284# and select "Modem"

5. Back to dial window

6. Press *#9090# and select "4 - DM over UART"default setting: "DM/DUN over HS-USB"

7. Phone automatically reboot

8. Hit Unlock

According to my device's information, is the firmware mentioned in this method compatible with my device. Is it safe, in terms of compatibility, for me to go ahead with this method!?

I'd really appreciate an expert opinion!

Thanks to All!
[Galaxy S 4 General] chopin00:
Is possible to restore simlock in inversely steps? For example, when I need use warranty.
[Galaxy S 4 General] ladyhaly:
I don't believe they'll be able to detect it, since the SIM-lock doesn't exactly tamper with the firmware. Stick to the stock firmware and you should be fine. That's what I'm doing as well, until after 2 years when the warranty is no longer valid for my S4.

Is it possible to revert this procedure? Any factory reset that will revert it back to what it was before?
[Galaxy S 4 General] mobileunlocked:
To the people asking if you can reverse an unlock...in most cases, no.

Unlocking a phone is permanent and conducting a factory reset will not reactivate the lock.

However, if the phone ever needs to undergo a major repair, the IMEI may be changed. If this happens, the lock will be reactivated and you'll then need to unlock it again. But anything you do will not change it back.

There will of course be people on here that are capable of doing so but I am speaking generally for the majority of viewers of this thread.

Is there any way to get rid of the network lock icon in the top status bar? It exist with any simcard even the one which was sold with. Phone is unlocked to all networks but the icon remains there
