Cannot Unlock Sim Samsung S4 Rogers

Hey Guys,
I have had one heluva time trying to unlock my Rogers Galaxy s4. I purchased an unlock code, which did not work. I tried through service mode. Then I tried flashing the rom to a factory rom, which has now disabled my cellphone reception. At this point I am trying to put the stock rom back just get my phone working. Is there anything else I can do?

FastGSM.com has been the "last resort / saviour" for many here when service menu didnt unlock nor purchased-code.

fastgsm
I also used fastgsm to unlock mu i337m using the usb unlock method

Never try it but it could maybe help you out ;

[Q] Samsung Galaxy S4 i9500 suddenly lost signal, imei, baseband, etc.

My i9500 has driven my crazy since yesterday, I even stayed up all night trying to find a way to restoring its IMEI. So here's the problem:
I was playing a game called "Friendly Fire" and decided to turn off its notifications using Application Manager. Everything was fine until a few hours later when I opened up my phone and saw the mobile signal was gone, only a circle with the diagonal dash inside it left. At that time I thought it was fine but then suddenly it popped up the message "Please enter SIM card unlock number" or sth like that, which was an error indeed because my i9500 is an unlocked version. I though it was the mobile network who locked the SIM, but when I tried putting the SIM into other phones, they all worked! And so I started to find a way to unlock my i9500 by ServiceMode Menu but I could never reach the ServiceMode Menu, it only showed a blank screen. I checked my IMEI and it now said "null/null". I had never rooted or flashed any ROM on it so it was really really strange. So I reached a topic on "how to solve the null/null IMEI" on i9500 because it seemed that many people got this problem. However, nothing helped I even rooted my phone to see whether I can back up then restore the 'efs' folder. Well, I did manage to do so but the IMEI would not change at all. The strange thing is that when the phone was just booted up, if I enter *#06# the IMEI shows "null/null", but if I enter *#1234# first then *#06# it shows the generic IMEI (0049...), which was useless as well. I tried different methods, flashing to different official stock rom, but nothing worked. Also, when I flashed an official stock rom, Kies did not show the right region of the firmware but "XXX" for every firmware I tried. And of course, my mobile signal was lost so I could not make any call/text/3G/LTE/etc., but the rest (wifi, bluetooth, gaming, etc.) was okay, it is basically an ipod touch right now
I wonder if anyone can help me with my problem? I know my real IMEI number (at the back of the phone) and that's it. I bought it from another country so it would not be possible for me to bring it to the Samsung store where I got it from. I could not remember the country where its first firmware came from Is there any way to find out that?
Many thanks for reading my trouble :crying:

Well this weird, I am wondering if an android virus could do that....

I bought it in the U.S. in July, from an official Samsung store. Well, the box containing the phone and the phone itself were "made in China", I thought most products have those words? It would be ridiculous if that is the problem because it also has a line like "Korean product"...
I wonder if Octopusbox or SPTbox may fix the problem? I don't know those two things very well though.

I had the same problem on a different samsung phone (Note 2) and i was getting imei 0049 or something like that, Basically my imei had changed or gone. The issue i found out to be a baseband issue so what i had done was downloaded a few compatible basebands and flashed them via odin and eventually got my imei back. There is also this link for you to have a look at http://forum.cyanogenmod.com/topic/77400-booting-issues-and-imei-loose/ just in case it helps. Hope you get sorted.

solve problem
According to your description， you can have a try resert your Samsung galaxy s 4 and then restart it to see weather it is OK? If it still not fine, send it to Samsung After-sales service

[Q] Blocked from AT&T after international travel

I have read through this forum for hours and in no way savvy with this stuff; I have learnt a lot so thank you but please help me.
I just don't know how to tell what the problem is with my phone therefore i don't know which of the 100s of solutions here to apply.
its a S4 i337 previously used on AT&T LTE network, I traveled overseas and used other country's sim card for a short time after giving it to service provider to program. i believe phone was rooted and settings changed for this to happen, though i did not do them or know what they did.
I returned to U.S. and reinserted AT&T sim, made one call, but phone seems to trigger anti theft or network suspend right after. I have had it unlocked twice by AT&T but first use thereafter seems to reblock me out of their network and i get message that this device is blocked from network use. When I call they say phone shows stolen and i repeat process above only to get reblocked again.
I don't know if it is APN settings, previous rooting or what that is causing this? I found an app called SuperSU on the phone, i clicked on its settings and clicked "full unroot" which made app icon disappear but can't tell if I am really unrooted or not. I have also done factory reset and lost everything already, I just want phone to work back on AT&T network as before.

Take it to a best buy Samsung service counter and have them reflash the firmware or update it to MK2. Wipe everything (including internal and external SD card) Then, call att to unblock it again. If it relocks, then go back to the Samsung service counter, tell them the issue and see if they can restore your efs for you from a backup. If they can, do it and then unblock it.
If after all this it relocks, its not your device. Its att who are at fault. Then all you can do is to yell at them.
EDIT:
Another possibility is that the ppl who unlocked your phone overseas stole your imei number and used it to revive a blocked stolen phone. In that case your imei is in an international stolen imei database and you are probably out of luck.

Interesting. If the IMEI was stolen, what would the phone show? Would they clone the IMEI (so it would show the same IMEI) or would it come up as UNKNOWN or blank or something. Reason I am asking is that I've been try to fix an issue with my father-in-law's phone that completely lost the ability to connect to wifi/data after having his S4 "unlocked" in Vietnam to use a local SIM there. Tried may reflashes with MK2 and custom TW ROM's but none work with wifi anymore (data works ok).

If data and calling works then the imei is fine. Its some other issue..

All is speculation but there is a small posibility that when you gave your phone that person gave you another phone which indeed was stolen. Your best bet is to go to the samsung guys right now or learning how to restock your phone. You tube search videos How To Unroot & Unbrick Samsung Galaxy S4

so its been a few days now with no service. it turns out my phone has somehow been programmed with a different imei that comes up as stolen according to at&t. so the theory of my imei having been stolen is pretty possible. every time i have the phone unblocked from the network, one phone call or message causes it to trigger the stolen phone alert and kick me out the at&t network. i have been to the at&t store with my device and the original packaging that shows my original and correct imei but the one that the phone is registering on screen does not match what is on my actual handset sticker and original packaging. the phone never left my sight the entire trip so i am 100% positive my handset was never switched, if anything it was reprogrammed with the stolen imei and they stole mine which is now working fine out there for some crook
i just can't believe that at&t can't verify my original imei that came with the phone i bought from them and just reprogram my phone and get my service going again. its looking like i will need to find a way to recover my imei myself. although i just got the 4.4.2 update that force placed itself on my zero service phone. hope this post helps to alert others to be careful of this type of thing.

Wow! what country did u visit?
If your s4 had insurance I would report the phone as stolen and give the original Imei to be blacklisted and try to get a new phone.

MY imei is different from my original S5

ok here is my problem
i have Samsung s5 from rogers
i when to Ghana so i wanted to use my phone there but it was lock so
took it to some guy to unlock it and it worked ok
when i came back and inserted my old sim
i get not registered to network and my imei is different from the box
i have tried flashing it with stock rom but still getting the same message
any body had this problem and how it they get it working
thanks

Unless you have made a backup of your original cert files nothing can be done, the shop in Ghana most likely used an IMEI from another handset and wrote it yours during the process this also unlocks your handset afaik .

Issue when trying to unlock the network

Hi there, I have an AT&T Galaxy Note 4 with android version 5.1.1
So back in August AT&T have provided me with the unlocking code which did unlock my device. Then two months after, my charging port has been damaged so I sent it to Samsung to get it fixed which took a month for them to get it fixed. Then they sent me back the phone after they changed (cosmetic parts, LCD screen, USB cable, charging port) even though the only issue i had was the charging port. Long story short, I got the phone back from Samsung updated from 5.0.1 to 5.1.1 but the device was locked to AT&T network.
I made a request again from AT&T for the unlocking code, but the code did not work. when I put in the unlock code it says "Network Unlock Request Unsuccessful"
The IMEI number did not change so I have no idea what to do since I talked to AT&T and they told me the only unlock code for the IMEI number I provided should do the job.
Then I tried to call Samsung and they said there is nothing that they can do, my only option is to sell my phone and buy another phone that is unlocked ????? please I need some help here. I tried Factory Reset but still no luck.
