i am using galaxy s4 for a year
it was not locked to any carrier
i updated to lollipop and didnt like it and then i flashed kitkat over lollipop
then i faced invalid imei issue
after many searches on google i found the solution of flashing rom and modem files will solve the issue
so i flashed few stock roms and few modems
now i got back my imei, my baseband version is correct
but when i check service mode *#0011#
it shows IMEI CERTI - FAIL
and it asks for sim unlock after every restart and cannot register to network
i guess that when i flashed few roms, one of those roms might be a carrier specific rom.
now how can i get rid of that, coz no carrier will give me unlock code because it was never locked to any carrier
Check the SIM unlocking thread in the General forum for added details, but in short, downgrade the modem to an Android 4.2.2 version using Odin, install RegionLock Away on the device, and run it. That will blow away the SIM lock so you can use your S4 again. Afterward, restore the existing modem.

When I upgrade my Samsung N9005 (European version) to Android 4.4, it does not detect any of my sim cards. I have tried this on three phones I have and am now sure there is a porblem with the firmware not my sim card. I am on China Unicom. I have also tried to insert a sim from a different country, it does not even ask for the pin since to it nothing is inserted. I have tried different region firmwares from HongKong, United Kingdom and Unknown. Please help.
Anyone?
How do I make my posts popular. I always ask questions on this forum and never receive answers. Yet there are 52k people online.
Be patient. You are not special that you should get immediate answers on your topics.
Thought about possible hardware failure? It could go under warranty as well.

Its not a hardware failure. I have three phones which I got after exchanging so this is six in total that have this issue. I also cannot downgrade back to 4.3 which is what I would prefer as for now.
What version of 4.4.2 you have? I need the build number.
I would recommend reflashing firmware, might eliminate those bugs.

I have tried 4.4.2 N9005XXUEND3_N9005OXAEND1_BTU and UK firmware N9005XXUEND3-N9005OXAEND1.
Just to add some detail, my phose Baseband is unknown and when I try to check the IMEI I cannot since it interpretes it as a phone call "Mobile Network not available"
Look around the forum, there are solutions for that. Apparently something went wrong when you updated firmware.

Try re-flashing the entire firmware, or extract only modem files and flash it manually. See the post here: http://forum.xda-developers.com/showpost.php?p=52948152&postcount=13

I'm experiencing the same issue. Flashed a new Temasek CM11 nightly and after booting into the rom for the first time no PIN unlock dialogue appeared. The phone is stuck at "searching for service". My IMEI number is still there and both SIM cards I have tried work perfectly in my iPhone.
I'm still on JB 4.3 bootloader with CMW recovery 6.0.4.5 and baseband is N9005XXUBMI6. Is it possible something got messed up when flashing latest CM? Perhaps baseband/modem firmware outdated?
I'm downloading N9905XXUEND3 and will flash back completely to stock. Will report back here later.

Sorry I've never tried CM so I'm not sure what happens.
Please feedback.

I have managed to solve the problem.
1. First back up EFS and FSG in case you haven't done that yet. On the N9005 your IMEI information is stored in FSG so do not use any tools that only backup the EFS without the FSG. For tools check here: http://forum.xda-developers.com/showthread.php?t=2611903
2. Flash stock image for N9005. I was still on JB 4.3 with the unlocked bootloader so I flashed JB 4.3 again, didn't bother with KK 4.4 which will lock the bootloader after flashing.
3. Booting back into stock and the SIM PIN entry menu appeared straight away.
4. Flash CWM recovery appropriate to your bootloader 4.3 or 4.4
5. Flash CM
6. SIM PIN entry and cellular works perfectly again
conclusion:
I'm not sure why this happened. Downgrading to a previous CM build did not solve the issue. So I'm reluctant to blame CM itself. Perhaps the recovery was the culprit. Somewhere something must have been corrupted during a flash. Luckily nothing that couldn't be fixed by flashing stock.
I used Odin to flash a NC2 firmware. I found the firmware in the thread will the leaked KK files. After flashing that firmware ive been unable to connect to Net 10 service with either a ATT or Tmobile SIM card. If i put the Verizon SIM in, i almost immediately see 3G is available. I flashed a second (updated) firmware, and i still have this issue.
Is this a known issue? Anyone else have this issue? Im using BigginsROM cause flashing Hyperdrive causes a black screen when booting. I presume its cause HyperDrive isnt on NC2/NC4 yet. I hope this isnt permanent cause itd defeat the entire purpose of spending $900+ on the phone and accesories.
Any info/help would be greatly appreciated. If ive merely derped something feel free to let me know.
First this firmware: http://forum.xda-developers.com/showthread.php?t=2528707
Then this firmware: http://forum.xda-developers.com/showthread.php?t=2787627
I installed a SIM card info app. The app says that the phone is network locked to Verizon. The phone number that is showed is associated with the Net 10 AT&T SIM. Still says network locked and SIM operator is Verizon.
While further researching the issue i found that the servce menu reports "Network: UNBLOCK." The conclusion is that that means the phone is SIM locked. How in the world would i have managed to lock my phone?
While even further researching the issue i found that it might be the NC4 ROM that i flashed when i was having problems getting the KK leak to boot.
Edit.
Ok this is the 4-5 Sprint Galaxy S4 factory unlock i have done. but for some reason this one will not work on metro.
here are the steps i followed
Phone was stock NG2
i factory reset the phone and installed the MDC Modem
i then did the internation unlock and then the domestic unlock.
after i did all this it will accept all sim cards but it gets no service with my activated MetroPCS Card.
so i changed the APN setting and still nothing so i called to metropcs and they said they needed to add the imei to my account. but when they try they say they can't add it to there system that the unlock did not go threw all the way.
so i then rooted the phone and installed CM nightlies rom and still can't activate it anyone have any ideas on what i can do and why they cant add the imei number to there system
no one has any ideas. could it of been because i was on NG2 rom with MDC modem should i of rooted and installed a rooted MF9 rom and then install MDC modem then run the process. any help would be greatly aprecaited
Could be that the imei is blacklisted?
that was the first thing i checked and everything came back clean on 2 different websites
Before you judge me by saying how i'm posting something thats done before, it hasn't, I've searched everywhere no methods work
Please, someone help me I've been at this for 4 days now and maybe just 15 hours of sleep :crying:.
The phone I have right now is the SGH-i337m Galaxy s4 running NC1 with MDJ modem (Kitkat 4.4.2) Does not detect sim, it says "No sim available".
I'm not exactly sure if the phone is from Bell but the phone use to be running fine on my old rogers sim card until I updated to their new ShareTap Sim.
With the ShareTap Sim the phone doesn't detect my sim anymore. So I tried my Share Tap Sim in another unlocked phone (Galaxy note 3) it worked fine.
Then I tried a Virgin mobile sim card on the S4 and it detected it and worked fine also. So then I tried to unlock it by flashing it with many different methods:
1. I tried flashing a older version of Bell 4.2.2 but it bricked my phone ( I already unbricked it back to 4.4.2)
2. I tried flashing the MDJ modem but it doesn't show the hidden menu.
3. I tried flashing ATT modem to try it but that also bricked my phone.
4. I tried to use the AWS tutorial shown here
5. I tried the regionlock away tutorial here in the third method (RegionlockAway doesnt do anything to my phone)
6. I pulled the modem.bin from the TAR file from sammobile of Bell's 4.2.2. But it still doesn't show the hidden menu! It's the MDJ modem but it still doesn't work!
I'm not sure whats wrong with my phone. When I put the Virgin mobile sim card in there it only shows Telus, EXT and Virgin Sim networks available not the whole spectrum which is what is supposed to happen with the 337_aws.qcn file from the AWS tutorial. Then when I flash MDJ modem from bell or the one from this dropbox link: https://www.dropbox.com/s/2m3id2cx4l...37MVLUAMDJ.zip
It still doesn't show my secret menu.
The secret menu I'm trying to access is the *#0011# but if that didn't work I also tried the *#9090# It still doesn't show the secret menu. So what do I do now? Please Help!
Thanks for reading!
Sorry to hear that, but you are in the same situation i was, the phone was probably sim-unlocked by Box Software, like Octopus or Z3X Boxes as i did, the phone won't recognize some sim cards by unknown reasons, there is no fix avaliable for this as i changed imei, tried different NVM from other phone & even replacing sim card reader. i finally sold it & got myself a i337m unlocked via code.
Edit:
forgot to mention, My SIM stopped being recognized when i upgraded it to a newer LTE version
Kind regards.
Have you tried stock NC1 with the included modem? If the device is unlocked, you might have better success with SIM recognition. In my case, my device was not unlocked, so I Odin flashed stock Telus MDJ, then rooted with CF-Auto-Root, unlocked with RegionlockAway (KNOX tripped), and applied the AWS Mod.
Then I flashed stock NC1 with the incl. modem (root gone), and managed to get Rogers LTE and Wind H+ on the Telus device. From there, I OTA updated, and rooted with CF-Auto-Root, flashed TWRP, and worked my way to 5.0.1. Trust me I know how frustrating this can be, but thanks to this forum, there was a solution. Here's what worked for me (link). Good luck.
Hi, i am new one to xda ..
I have a Galaxy s4 I9505 with "sim network unlock pin dismiss" Unlocking Problem.
i install Android lollipop(UK) rom to s4. before install lollipop i had this problem'
I tired trying carrier Unlock Methord [*0011#]. but it dosnt work for me. That menu isnt work in my device.
I am from sri lanka. in Asia. How can i fix this. Waiting for replies. thanx
The service menu unlocking method was patched in 4.3 and later, thus it's no surprise that you have no menu.
Given you upgraded to lollipop, your option is to purchase an unlock code online and hope it works.
You can go back to ROM 4.2 and redo the *#0011#, or if I'm not mistaken, the patch is in the modem, not the ROM itself, so try to flash the "early" modem (ex : I9505XXUAMDN) that you can find here : http://forum.xda-developers.com/showthread.php?p=39176955#post39176955 and then do the *#0011#
Another method that could work (if the *#0011# failed) : use RegionLock Away (http://forum.xda-developers.com/showthread.php?t=2470551), also with 4.2 ROM (or ealry modem), you need to root to use this app.
The thing about RegionLock Away and the service menu unlocking methods is that neither is guaranteed to stick if you upgrade. At least if he pays for the code he's unlikely to ever have to worry about it again. That said, I've recommended RegionLock Away in the past, when Android 5.0.1 was not yet out. With that version now available I'm holding off. I'm concerned that Samsung changed the modem in such a way as to guarantee restoring the lock on an upgrade. Perhaps the OP could serve as a test case.
I'm using a "modified" modem using RegionLock Away and can confirm that it works well after upgrade to Lollipop but as I said, RegionLock Away only works with "early" modem, one must first reflash the old modem, patch with RegionLock Away, and then can freely upgrade modem & ROM, the unlock will stay ^^
