HELP! Can't access service mode to unlock phone - S4 I9500 - Galaxy S 4 Q&A, Help & Troubleshooting

Hi
I want to unlock my galaxy s4 and I've tried the method of dialing *#0011# to enable service mode and unlock the phone from there, but when I dial the code nothing happens.
I've factory reseted my phone a few times, changed sim, done without a sim etc and nothing seems to work.
Strangely, only a few service codes actually work on my phone such as *#06#, but most others don't work
I'd really appreciate of anyone could tell me how to solve this problem
Thanks

I'm on t mobile and my phone won't show anything either I think it's to do with t mobile mate

Cant unlock device after rooting

Iv been rooted for over a year and have flashed everything possible for this device! !! I LOVE THE HD2... I just recently switched to att and purchased the unlock code to switch sim cards and i cant seem to unlock the device. I went back to windows mobile in hopes that it would prompt me for an unlock code on start up with no such luck. Any help on this matter would be greatly appreciated!
Many thanks in advance . .

Odd, it should deff ask for a code under winmo, what does it show? No network?

Definitely it should has asked for a network code under Win Mob, very odd indeed!
Thanks for the response. It seems the sim card wasnt getting contact and now i fixed that issue. Now i have a different problem.. it now asks for a pin and when i enter it all is well and its excepted. I go to make a call and it says i need to enter the pin! Iv done this a couple times and still nothing.

Probably same area problems: contact between sim-card and device, faulty sim or sim-card slot...
two known bugs on unlocking HD2; try pressing & holding OK button for 5 seconds when code entered, do factory hard reset after code been accepted.
As above, you could still have sim card connection issues causing full connection call issue !

[Q] No Network

Hi, one of my friend sent me S4 and now after i am trying to use it shows no network however i am able to see contacts on it.
I checked with my operator and nothing is wrong from their side.
I am able to view the IMEI no as well.
After reading couple of solutions when i am trying to get into service menu using *#0011#, it does nothing and stays on dialer screen
Need help
Just for your information i am from INDIA
*#0*# to get into information screen.

IMEI:unknown

hi Devs, im from Philippines and my phone is from Canada.. My phone is at&t sgh-i337. I went to cellphone shop to unlock my phone and it was successful. My problem is when i go to settings>about phone>status, in the IMEI:UNKNOWN and IMEISV is 12. when i manually press the dialler *#06# it appears IMEI: 12/.. Is it normal? thank you for the anwsers..
No it is not normal. It sounds like they messed up your efs in the process of unlocking it.
It will probably work fine since your wireless service provider is not blocking the generic IMEI

-I Can receive text and calls. but the unknown thing makes me annoyed.. Is my s4 will get bricked if i will not fix the imei sir?
It won't be bricked.
If you move to another wireless carrier that chooses to block that generic IMEI then you will not have service until you get it repaired.

[Q] can't connect to mobile network

Hi I purchased an s5 that was a few days old 2nd hand. I checked everything out on check mend and everything was fine, few days after purchase, phone will not connect to my network or the 02 network with any Sim. I spoke to 02 and they tell me the phone is not blocked or stolen. I also got a receipt from the guy I bought it from, but like I say it worked fine for a few days then this happened and now nothing. I managed to reg the phone with Samsung, although I do not know if I can get away with a warranty repair, as I am the 2nd to own it, even though it really was new when I purchased it. Anyway, any help would be Greatly appreciated.
The provided info was not enough to investigate the cause of the problem.
What you have done or installed or changed in these few days
Forgive me, I am new to this.
I have tried both 02 sim and a giff gaff(my provider) sim in the handset and nothing works. I am going to pick up another sim this morning to test that also(different carrier). Both Sims i have already tried work in other phones fine. The giff gaff sim when I put it into my daughters s3, works perfectly and calls can be made and received.
I was considering flashing another stock ROM just to eliminate software, I have opened a support ticket with giff gaff, who have said the sim is fully active.
Just trying to add bits that are useful here, the imei of the phone is fine and shows up as being there and not null, everything else on the phone seems fine also in terms of usage, I did have mobile data, which for some reason I can't seem to get now, but I did re write the APN, so will re put it to the original. Just won't register on network.
Anything I have missed or you need please ask. I am a noob, although I have flashed a few ROMs without issue after lots of reading. Should also add, the phone is completely stock, nothing messed with in any way. Sm-g900f. Xxu1ang2.
Thanks in advance.

Enter the code *#0011# and check the last line, IMEI CERT = PASS or something else?
APN is not required at this step (register to the network).

Hi, that code brings me am error" not registered on network" although I now have a data connection again on 02 and am at least getting 3 bars on the analogue signal, just not registering. I have just put in a Vodafone sim, which it recognises as it pop s up and allows me to select Vodafone pay as you go, but still does not register. Icon Just keeps spinning.
***********************UPDATE******************8
I just ran that code with the vodafone sim, it produced this exactly.

and then there are some options on the top menu.
thanks again
Thanks in advance.

1- Is your phone rooted?
2- Enter *#2263# (*#BAND#) and see which option is currently selected?
3- Enter *#7465625# (*#SIMLOCK#) to check for the lock status?
...
8- The pre final step is factory reset your device
9- The last step is reflash the stock firmware using Kies or Odin

Hi,the phone is not rooted, those codes you gave give "not registered on network", i have factory reset the device a couple of times now.It is actually my daughters phone and was working fine, she turned it off whilst at college and then turned it on and it seemed to not allow calls and texts from then after about a weeks use, 5-7 days.

Since you have factory reset and it does not help, try to relash the stock frimware.
Install Phone INFO ★Samsung★ app, go to the Menu 'Firmware Browser' to download the desire firmware, and flash using Kies or Odin.
had to post this way

Hi, thanks for responding so quickly, that was my next move in all honesty, just seems weird. so there is nothing that stands out in the quote? my wife also has an s5 and where the quote from the first code given, hers said "available" where mine states limited., just thought i would add that incase it meant something.
Thanks for all the help.:good:
sorry for the delay, it would not let me reply to the other post as i am junior and there was a link in it, so i had to respond this way, excellent app by the way, many thanks for linking it. I am going to have to thank you, i do not know how, but i will have a search, you have been most helpful.
STOLEN
***************************************** U P D A T E *************************************************
I just ran another check mend report, after being told it was not blocked by 02, it now appears that it has been blocked and reported as lost / stolen.
Anyone any ideas on where to go with this?
I have receipt, 2 check mend reports, 1 clear and 1 not, clearly an insurance swindle going on, phone companies not interested
Thanks in advance.
