o2 UK unlockable?

Hey all ive been trying all day now to unlock my O2 UK s4, i have 2 other s4's one of which was vodafone and it unlocked no issues atall, However the o2 branded one i cannot get to unlock tfor the life of me.

I tried unlocking it whilst it was on the release firmware i didnt update the fw atall.

My vodafone s4 unlocked no issues with this method.

Tried searching forums and seems all on o2 uk/ireland seem to have issues?

Any1 succesfully unlocked UK O2 s4 yet?

Really stuck here.

Bell S4 - SGH-I337M - not working =/

Thanks for the guide! But it's not working for me for some reason. I followed all the steps and at the very last step it does say the Golden-Backup exists and then I hit [4]Restore Backup. The phone reboots, blue LED, menu and back lights are on and then when the phone fully reboots, it still says "invalid sim"

Any tips/suggestions? The phone is currently locked to Bell and I'm trying to unlock it for a Fido sim card.

Thanks!

Not working

Hi guys.

Im in Ireland locked to Vodafone IE.

I tried both steps. There is always same problem. Cant get into the menu mode in service menu.

1. Dial *#0011#

2. press Menu then tap BACK

3. press the Menu again the tap KEY INPUT then enter 1, (wait a few seconds) it auto jumped into service menu.

4. press Menu then tap BACK

I dont get into service menu, just ended where I started. Seems like the phone is somehow locked to get into this menu.

Any advice?

Thanks

Hi,

I believe the modems are in this thread.

To my issue. I got a 9505(non-G) from Three UK. The service menu unlock is not working with ME2 modem. Sometimes golden backup exists, sometimes it does not, the SIM unlock is unsuccessful every time. I probably did the procedure like 20-30 times. GalaxySimUnlock also does not work as the model is "unsupported". Should I assume that at this point you cannot sim-unlock S4 from Three(UK)?

I saw that people reporting successful unlock have a lower kernel version(SEP-136) and I have 137.
[Galaxy S 4 General] chubby65:
Dunno mate but it couldn't hurt to try it
[Galaxy S 4 General] xciter327:
I did try it and it does not work. I quickly re-read the thread and it seems that people with unlocked Three(UK) S4s have lower kernel version than mine. I will try downgrading completely(fresh install) to ME2. Also TWRP and Clockwork do not properly work on my phone. When I try to enter them the phone just restarts.

Hi Guys,

I have a globe locked i9505 and the method to unlock it does not work. I can't get to the service menu.

I have noticed that some guys from the Philippines who are not on globe locked phones seem to get it working.

So I was thinking, would it be possible to change the firmware to something that has been confirmed to work (like firmware from Smart or another country's Firmware), then do the unlocking?

Has anyone gotten this to work on an AT&T Galaxy S4 (SGH-I337) with the I337UCUAMDL firmware?

I followed all the steps (inserted an authorized AT&T SIM, set PERSO SHA256 to OFF, did a backup restore, etc.) but it still asks for an unlock code when I try another carrier's SIM card. Perhaps I need to downgrade to I337UCUAMDB first?

I'd tried the hidden menu method and it failed. Then I bought a SIM unlock code from a website and it didn't work either (yes, I set PERSO SHA256 back to ON before entering it). Finally, as a last resort, I tried the FastGSM USB app and it worked :)

I think the unlock is "fixed" in phones with newer kernel versions. If you could spare the money try the app linked in the previous posts
[Galaxy S 4 General] egandt:
I have an AT&T S4, with CM10 installed, I attempted to unlock, but no Success

I bought the code, borrowed a t-mobile sim, rebooted the phone I get the screen asking for the unlock code, which I tried. It fails to unlock the phone (bad code), I tried 2 other times with the same result, bought another code (well same code from a different place), tried again still no luck (same error as it was the same code).

Now it is possible that the code will not work if you have a custom ROM, but I found no refrence to this anywhere or anything else which could be wrong with the codes I purchased, have I verfiied IMEI is correct, and since both sent the same code I assume the code is also correct, but I'm having no success use it. I have never used the free method, described at the begining of teh this thread.

Assume it is not related to teh Modem, but I'm on: I337UCUAMF3 (newest), as well.

Ideas? Since reflashing the phone with a stock firmware, is well a whole bunch of pain I real do not have time or access for at the moment.

One person suggested not removing the battery, but it is impossible to remove the sim without doing so.

Thanks,

ERIC
[Galaxy S 4 General] xciter327:
I think you have to flash to stock ROM(as this method is not available on custom firmwares), change the Perso field to enabled(1) and try the code again.
[Galaxy S 4 General] egandt:
Reflashed the AT&T ROM, boy do I hate this ROM, then tried again, still no luck, I tried:

Insert a non accepted sim card, and enter code when prompted for a code

"Invalid Code", same as on CM10

Go to the dial screen and press: #7465625*638*UNLOCKCODE# (8 digit unlock code)

"Connection problem or invalid MMI code"

Go to the dial screen and press: #0111*UNLOCKCODE# (8 digit unlock code)

"Connection problem or invalid MMI code"

Go to the dial screen and press #7465625*638*# Once prompted for code, enter 8 digit code

"Connection problem or invalid MMI code"

I did not want to risk the free method, but am seeing no other options.

So I entered *#0011# and the menu appears, although mine has a number of different fields, then I follow though getting to "Your are now in the SERVICE MODE MAIN MENU", however after entering 1 "OK" the back, I'm not in this menu, but this the initial screen. Given the very many differences in what is shown and the fact that I'm not getting to the main menu, this seems like a bad idea.

Only thing I can think of is even though I'm back on Stock firmware, I still have a CWM recovery and am Root'ed, but there really not things that other people have not done, based on the previous posts.

So basically I've tried just about every possible method I could find to unlock this phone over the day, and I can not locate any that actually work on my phone. I worried to go any further using the free method as mine does not match up and the unlock code no match how you attempt to enter it as such does not seem to be valid. I do not want to lock myself out of the phone, but I do not see any way to continue safely with unlocking the phone, any thoughts?

I have a UK S4 locked to O2, I tried this method and even though the SHA256 was 0 it still didn't unlock it. After a while I couldn't even get into the menu of the service menu, I type in 1 and nothing happens (might have started doing this when I flashed a different firmware?) also sometimes it was telling me no backup existed so 4, 5 were not available, so I had to make a new backup(!?) so perhaps that's why its not working now, but I did try this a few times so might not have been that which has locked me out of the menu.

I just bought a unlock code off eBay for £7.89 which was the cheapest for Euro S4's, worked fine - still can't access the service menu though :mad:

Flash the ME2 modem mate that'll allow you into service mode again
[Galaxy S 4 General] egandt:
So modems are related to Unlocking the SIM? as I can switch to a different modem, never thought that could be a cause.

Never mind flashed back to UCUAMDL from I337UCUAMF3 same exact errors exist, still can not even get the status of the sim, which as I understand it is what *#7465625# does by it self.

[Galaxy S 4 General] egandt:
Got it working , needed to use modem UCUAMDL and a stock ROM image and everything just worked. So simpole put if having issues either with the free method or using an unlock code you need to have a stock ROM and a modem UCUAMDL or earilier. Both are very good to know.

Thanks,

In my S4 (from Orange Spain) with ME2, MF4 and MF8 this method doesn`t works.

The SHA value was 0, I tried with 1 and 0, but I was not able to unlock the phone. I tried to disable / enable data later and nothing.

I always get the same, gives as the NV backup this before or not, whe I go to apply the backup (golden image) comes an error window.

Finally, I called Orange Spain and asked them for NCK code for samsung to release it, so now I have unlocked free.

I followed both tutorials in the OP, however the phone is still locked (T-Mobile Austria). I'm on I9505XXUAME2, unrooted, just as it came out of the box. The service menu is available. The only difference to what was mentioned in the OP that after hitting "RESTORE BACK UP", I got a screen that was empty apart from it saying "Error" at the top, and after less then a second, the T-Mobile animation show, the screen stays white (not black!) for a good few seconds while the blue led is pulsing, and then the phone reboots. However, after that, it is still locked. The same happens if I select "LOAD DEFAULT NV".

So, my questions: did you guys root the phone before you tried that? Should I try downgrading to MDM baseband, even if the service menu is available in ME2? I'd be grateful for any input :)!

Same problem here, except I've updated my original Orange rom with an MDM one.

The question here is what is causing this "error" screen that pops up after hitting "restore backup" or "load default nv" ?

Maybe files are protected and we should add the Write rights on them ?

I remember unlocking my I9000 by editing the nv_data.bin file by hand, wouldn't that be possible for the I9505 ?
