Hi, here's the story, I flashed CM10 but because I'm new with this phone model I didnt new I had to bacup my eff folder, so when I flashed CM10 it changed my imei, now I cant make any calls or whatever that requires network, I read in here and other forums that I can repair that going back to stock gingerbread but the thing is that I suddenly I can't enter download mode, I tried entering through "adb reboot download" and it only reboots, I tried with the volume +/- pluging usb cable but it still doesnt works, the only method I havent tried yet is with the jig, which I would have to buy or make myself, so I was wondering if I can flash the stock rom from cwm, I couldnt find any zip of that rom, only the odin ones, could you please tell me if I can do that? or gime me a link to the stock cwm flashable rom?
U can only go back to Stock through Odin, Heimdall or mobile Odin.

I'm in a similar situation for a different reason. My USB port is broken (bought phone used and it came with a beta CM9). Having problems with not getting any mobile service so I want to flash back to stock and start there. While I'm a software developer, I'm new to smartphones so I want to make sure I get this right.
It seems I can't just download the one-click because it needs USB. You said above that "Mobile Odin" could be used with the one-click if you have root. I assume I do, but what is the tell-tale sign of that? From all my reading so far it seems you can lose it also. Anyway, so if I d/l Mobile Odin from the Play store and d/l one-click with root onto my SD card, I should be good to go - just run the app, select the file and follow the instructions and I'll be back to stock Froyo?
Thank you!

If you are on CM9 then you are most definitely rooted. However if you want to check go to your app drawer and check for a superuser icon or Super SU icon. If you have either one of those you're good to go. I've personally never used Mobile Odin but I would have to say what you described sounds like the right steps. My question to you is why not go to gingerbread instead of froyo?

Yep, I have the icon. Why do you sometimes lose root when flashing a different ROM? I wouldn't think simply having that app is all there is to it. Anyway, I noticed after I posted my query that the Pro version of Mobile Odin has "EverRoot" so you never lose root apparently.
I figured I'd start with Froyo since that is what my phone should have shipped with and what my new carrier expects. If I still don't see any mobile networks, I figure I'm down to a SIM or hardware problem. I can get wifi on my home network fine, but I live in the middle of a city and see nothing show up when I do a Search for Network Operators. Perhaps I'm wrong being new to these, but I would think I should see at least AT&T, Verizon and T-Mobile appear on a list when I search.
The odd thing is when I do Automatically Select a network operator is says I'm "registered on network" yet there's no signal (-110+ dbM and 0-1 asu) and phone status shows me as unknown network and disconnected.
If it does work with Froyo, I'll work my way to GB and ICS and back to CM to see where it breaks.

Well pretty much every custom ROM you install is rooted from the start. If you were on a stock setup you wouldn't be rooted unless you had done it yourself.
With your current setup go to settings>about phone> status and compare the imei listed there with the one under your battery. Also check settings>about phone and look for your baseband. If your imei matches but your baseband says unknown then you are missing a modem and that's fixable without going back to stock. If the imei doesn't match then your efs folder has been erased or corrupted and you will definitely have to go back to stock.
Also if that's the case once you get back to stock backup your efs folder to prevent future issues.

So flashing back to stock WITH bootloader keeps the root (but then you're not technically 100% stock since it didn't come that way).
IMEIs match.
Baseband is I9000UGKG3. I'd also thought of trying a diff modem but this one works for others obviously. I'm in the Midwest if that makes a difference.
Other Status info...
Network: Unknown
Mobile network type: GPRS:1
Service State: Out of Service
Mobile Network state: Disconnected
It does list my correct phone number
IMEI SV: 09
Another newbie question: whenever I do finally get service, how can you tell what speed the data connection is?
Thank you for your help.

Actually stock with boot loaders is just that. Bone stock with the boot loaders added into the flash package you won't be rooted with that package.
The fact that your imei is correct and you have a modem but still have no service is concerning... are you using it on att or are you trying to use a different carrier?
As far as data speed when you're up and running use a speed test app from the play store.

I'll worry about figuring out root stuff later if needed.
Phone was supposed to be unlocked. I'm using it on an MVNO that uses T-Mobile's network. I get no errors or messages when inserting the SIM card so assume I am indeed unlocked. It does load 3 APNs that happen to also use T-Mobile but I must manually enter the APN for my carrier, which I've triple checked with their support.
I'm leaving now to swap SIM cards from the same service on a known good phone to see if mine works in that phone or that one works in mine.

I could be very wrong but it sounds like you're not actually unlocked. Or as you're checking your sim is messed up

Hmmm, is there some way to check other than throwing in a random SIM? Unfortunately, my SIL's phone is newer so she had a smaller SIM card
Most people seem to get a card locked message if they are not unlocked and install a non-AT&T SIM.

It's not the easiest thing in the world to do but I couldn't come up with a different way... http://forum.xda-developers.com/showthread.php?t=761045
That is actually a link to a tutorial on how to go about unlocking it. The way I see it is if you follow the steps you'll know if it was already unlocked and be able to unlock it if not.
I know that the process works because I followed it to unlock my own captivate.
Edit: I did the manual way and did not use any of the apps listed.

Seems that way. I'll still try to wipe as clean as I can back to stock and see if there's something wacky in the software that's preventing signal.

Check the sticky thread in the development section for the one clicks and flash back to kk4 stock. It is bone stock and then you can move back up from there. It will not touch your unlock though.

I picked up another used Captivate and this one works. It came with KK4 and a good USB port. I'll flash something onto it soon once I learn how to properly back up everything.

Hello,
I have searched multiple forums for hours today and have figured out what is going on with my HTC Vivid. (It has been upgraded to AT&T Official ICS.)
It was working fine up until yesterday where it was not receiving a signal from the mobile network and the signal icon has an X through it. The SIM card is properly inserted and another SIM card has been tried as well. Looking through other threads it seems like the Radio RIL files may be missing or corrupt. The IMEI number and *#06# code does not show an IMEI number either. The baseband version says unknown. I am not sure what happened as I have never loaded any other ROM on it.
I downloaded the Official RUU ICS upgrade ROM today and tried reflashing it, with no luck.
What is interesting (and the other person who had the radio problem) is that when I left the phone sit off overnight and then turned it on in the morning, the phone connected to the mobile network and I had a signal. When I restarted the phone, hours later, the phone lost connection to the mobile network and that is when I started digging and found the problem with the baseband version being unknown.
Is there anything anyone can suggest? Can I reflash the baseband files or copy them from someone somehow using ADB? It seems like there is where my problem lays. I've searched for ways on how to downgrade from ICS to the official GB stock rom, but it doesn't seem like it can be accomplished.
(I tried downloading the Holiday Cingular version of the GB stock rom but the update failed. I read about the ICS HBOOT version being different and not allowing it.)
Thank you in advance for helping and any suggestions.
Have you gotten a new sim card yet? That needs to be your first step. My captivate did the same thing and turned out the sim went bad

Yes I have tried a different sim card. I don't believe thats the issue though being that it worked with the same sim after I let the phone sit overnight. From reading about others experience, it doesn't seem that the sim is the issue but more the baseband version and imei information missing.

I had a similar problem and thought I solved it, but I later realised all my "solutions" didn't bring back the network but coincided with its reappearing cos no same "solution" worked more than once.
It's a very weird problem as the network shows up once in a while and when I'm using Mobile Network for Data, my phone hangs again and the IMEI, Network, baseband disappears on reboot...till further notice. I gave up trying and concluded it's either a bad modem (hardware) or something AT&T knows about!
You can get HBOOTS for both GB and ICS via Hasoons AIO kit
Flash the HBOOT, Flash the Image from Cingular GB RUU and I wish you luck!!!

I found the download link, but the website says they're updating their drives, so who knows how much longer that will take.
Also, are you saying I should just use the tools within the kit to flash the HBOOT back to the previous version compatible with GB and then flash the RUU GB image after? Can I do that with the phone connected via USB or does it have to be flashed from the SD card? If it has to be flashed from the SD card, how do I go about doing that? If it can be done from the phone via USB, does the phone have to be in recovery mode?
I have tried reflashing the ICS RUU multiple times w/ version 3.26.502.52 and 3.26.502.56, both do not fix the issue. Do the baseband and or radio files NOT get flashed within these updates?
Thanks for the response!

Thanks for the quick reply.
Your thread was the one I saw earlier with the simliar problem that I am having, only I have not loaded any custom ROMS. The phone just stopped receiving the signal the other day. I am still waiting for the download website to become available to use the tool to perform the flash of HBOOT, however, once I do that, will that erase the ICS rom from my phone? If so, what steps do I have to perform to get it in a "download mode" to accept the AT&T GB RUU? I'm a little confused on that part.
I read your first thread and I am a bit confused on exactly how you were able to correct the baseband/RIL issue (which I am assuming is the root of my issue). Do I have to extract some files from the RUU executable? Are the commands you provided to be used in ADB? I am confused as to what to do with [setprop ro.baseband 3.26.5XXX (<--- mainver: in android-info.txt in RUU.zip)] from your post. If that command is copying a file or just setting information (almost like as a registry setting within Windows) to point to the file or set a version number. Also if the XXX needs to have a certain number.
I thank you for your time and am trying my hardest to understand what to do to accomplish these steps.

I did find the extracted files within the RUU executable and found the rom.zip which included the .img files among other files I assume needed as sources to flash the phone. I see a radio.img file would I be able to do anything with that?

And I have a question, if the radio/baseband files are included in the RUU flash, what is happening as to why it is not being reflashed, or if it is being reflashed, why it is disabling the mobile network and providing an Unknown version to Baseband and clearing the IMEI number?

Here's where I am:
I successfully unlocked my bootloader, downgraded to GB, rooted. Tried to gain root access through adb terminal but it was not working properly.
I relocked my bootloader. Installed the ICS RUU AT&T ROM update. Unlocked my bootloader, rooted.
I see the commands you ran in your previous post. I am also receiving the same message of N/A when running the getprop ro.baseband
I tried the second command setprop ro.baseband 3.26.5XXX and then restarted the phone. I have tried it as posted, and also with swapping out the version that is located in my android-info.txt file: 3.26.502.56
Still no luck with setting the baseband version. IMEI still is cleared out.
Am I doing something wrong?

Hey thanks for all of your suggestions. I contacted AT&T the day everything happened to see if it was on the block list. They said no. I tried multiple things including trying to re-flash the radio, but I was getting a signature failed error that I could not get around. I really think that's what the problem is. I gave up and ended up selling it.

Exactly. It was my sister's phone. The sh*tty thing is we bought two off of ebay at the same time, 1 for me, 1 for her. Well, her phone was not in the box (either never shipped or stolen) so I had to file a claim through eBay which took 3 weeks to get the money back. Meanwhile, I gave her my phone (which is the phone in reference) to use instead. I bought her an iPhone instead now, along with purchasing one myself. I loved Android, but the bugs and fragmentation is getting too much for me to handle.
Dude, if you don't have an IMEI showing up, something is WAY wrong. That goes beyone the RIL not working... The RIL is probably fine. If your phone doesn't have an IMEI somehow, the cell towers are NOT, NO WAY, NEVER EVER going to register your phone on their network. You can put a billion SIM cards in there, or flash a billion stock ROMS, and if you don't have an IMEI, you will never be able to connect.
Something is probably corrupt or broken in your firmware or the hardware itself. I think your device is probably screwed.
My advice, is follow the steps to put your phone back to stock (including changing the bootloader message back to **LOCKED** and S-ON), and get it back to the phone company. They will be able to tell something is boned on the phone right away since it isn't displaying an IMEI.
Sorry to be the bearer of bad news and for your many wasted hours... But on the plus side, you now know a LOT about flashing and how your phone works now
Good luck with everything man! Hope they get you up and running soon!
I have the same problem as the OP but I have a IMEI showing up and a Basehand But won't connect to AT&T or anything they resent me a Signal & everything it shows a X with no bars it happened after I did a Factory Reset

That's weird..you try creating the apns again? I don't see how a factory reset would do that. Try toggling airplane mode too

I am currently having the same issues right now, it works if i leave the phone off for 1 hr it will work until i reboot then its down again, tried every thing possible, airplane mode will crash, reflashing the radios from gb and ics does nothing, setprop does nothing really. from this point it feels like a hardware issue.
sorry to revive an old thread, i just wanted to know if anyone came across this issue and had it fixed
i will get a log to see if there is errors showing up
Return it.

I have an unlocked Captivate SGH-i897 running Jelly Bean (Slim Bean). I am trying to use it with a T-Mobile Sim card. I cannot connect to data in any form (wifi is fine), texts come in and go out but take a very long time (about an hour), and calls do not work (with the exception of one time one went through), saying "Mobile Network Not Available." I never appear to have any bars even though I am in a major city (Boston).
Data and data roaming are enabled. Airplane mode is not on. I have removed the battery and reseated the Sim card. I have tried every APN under the sun and soft reseted.
I have read about other people experiencing the same problem on these forums and elsewhere, but I have yet to find a solution that meets my needs. Thank you for your time.

you probably have the same error as me, you might have forgotten to backup your eff folder, return to stock, bacuk those folders, flash again slim bean and then push the folder files, that way you will repair the network

As stated above your efs folder could have been deleted in the flash which is common. Easiest way to figure out if its gone is to check your imei in settings to the one under your battery. If they match you're good. If they dont you'll have to restore your efs folder. If you didn't back it up manually you'll probably have to flash back to stock. But before you go through that check your internal SD card for a folder simply labeled backup. If you have that folder look and see if you don't have a copy of your efs in it. Some ROMs actually create a backup during the flash.
If your efs is intact and you're imei matches then the only other thing I can think of is to check to make sure you have a modem installed. Or look into flashing a different modem.

There are several apps available in the play store but the only one I've used is nitrality. It should copy it where it is supposed to go which is /efs.

I'm having the same problem. I checked my "about phone", and I don't see the imei value. But it is on the root in efs. The value matches the one on the back of the phone, and so does the one in sdcard/backup/efs.
So, how would I getting a new radio/modem?

dial *#06# - it will show you your active IMEI.
- DC
Anyone get this working? I made two backups: 1 copying the files and the other with nitrality. Neither worked and I have not been able to access the mobile network with my I897.
I had the same issue (or similar).
In my case I was not able to hold signal for more than a few seconds on 850 MHz, which is the frequency of my main carrier, however, my secondary carrier which uses 1900 MHz band, worked flawlessly.
I fixed it by installing a different modem.
KC1 seems to work great.

Phone will not recognize sim/ imei "Unknown"/ baseband "Unknown"? *Updated*
Updated title because problem has now changed.
current problem--
Phone is stock, randomly stopped getting signal factory reset phone using keypad, now phone will not recognize sim card, the imei is blank and the baseband is unknown. Tried reseating the sim, and powering on off.
initial problem--
After having a problem free note for some time now it randomly stopped working. I cannot make a call/ text or use data but the wifi works and the phone functions outside of those uses. When making a call I get various errors in the form of Mobile network not available/ Not registered on network and when i go into mobile networking settings> network operators it takes a while when searching and tells me to either try again later or gives me a message "error while searching for networks." When i take the sim out all together I get bars of service but when the sim is in it either gives me a circle with a line through it or a empty signal bar triangle.
I called straight talk customer support as i thought it was a problem with the service and they told me I had a bad sim card. I have since checked the sim in another phone and it works fine. I have tried multiple working sims in other phones and no luck in mine. The phone appears to be recognizing the sim as the apn settings are adjusting based on what sim i put in. I have tried to take out the battery, take out the sim, factory restore but nothing seems to work. I have also checked the imei number online to see if it was blocked or something and it said it was not. I took it to a local phone repair shop but after toying around with it for a hour they didn't know what was wrong, so here i am, hopefully someone can point me in the right direction. thanks.
May be the phone is network locked. is it asking for some kind of key or pin anytime or when restarting the phone?
where did this begin to happen?

I know the sim isn't the problem as it works in another phone.
You may want to try flashing stock GB with PC Odin...then with stock GB recovery do a factory reset.
Don't do anymore factory resets if your on ICS and completely stock - you will kill your device...see the brick bug sticky

I'm assuming i have to root my phone in order to look at this folder? I'm looking into this now.
yes.
when restarting phone do you get the password prompt for the sim pincode, could be sim is not registered?
Anyways a stock phone should not do this. Its a case for customer service to fix efs. That appears to have instantaniously corrupted(!) first case I have ever seen of this.
Almost cannot believe it.
Without sim, is the imei there? I am suspecting your emei was gone before which you never noticed then. Is it even a new phone?
note rooting might void warrantee, so be careful

I used es file explorer and within the efs folder there were 5 mb worth of files.
Okay, I just got through doing this myself and it seemed that nowhere was this all said at once, or at all. So I thought I'd whip up a quick tutorial concerning how to Domestic Unlock the Samsung Galaxy S4 on any of the newer bootloaders/firmwares/modems. (Knox-enabled)
I did this on both a 4.4.1 galaxy and a 4.3 galaxy- one one NAE and one on MK2
First, for anything to work your modem must be an older one, like version MDL. Download the file SPH-L720_MDC_Modem.exe which is a one-click
Odin .exe that will flash ONLY your modem to MDL.
Steps- put into download mode by taking the battery out and putting it back in. Hold the volume down button, the home buttone and then press the power button. When it vibrates, let go. Press volume up.
Run the SPH-L720_MDC_Modem.exe odin one-click installer.
Connect the usb to computer from phone
when com[24] or whatever shows up, press start.
Now, for the domestic lock to work you first need to do the international unlock @ http://forum.xda-developers.com/showthread.php?t=2415587
It's real easy and explained well at the link above, but I'll run through it quickly anyways.
Download the s4unlocker installer from the post linked above.
Put your phone into diag mode by dialing ##3424#. Press Qualcom button and select the bottom selection.
connect (if it wasn't already) usb from phone to PC
You already installed the proper samsung drivers, right? If not, you'd better do that now.
Okay, now run the s4unlocker and press the scan and unlock button, then wait for the phone to reboot.
Now for the Domestic Unlock part.
Follow the directions at http://forum.xda-developers.com/showthread.php?t=2530610
I'll run through it real quick, too because there were a few things I wanted to mention.
dial *#0011# (or #*0011#, I can't remember)
when it comes up "No service", press the menu key on the bottom left of your phone. This brings up a menu (wow!), on which you should press "back"
Now press the menu key again and in the menu select "key input" A box will open up asking for you to type in something- enter a "1" and then press the enter key BEFORE hitting the OK button. Mine would not work unless I did this.
Now wait, sometimes it takes a good couple of seconds to give you the menu. Follow the rest of the directions from the above link, setting all the settings to what is stated. EXCEPT where he says to set all the preferences to WCDMA ALL, GSM ALL and LTE ALL. When I selected one, however, an asterisk appeared after my selection leading me to believe that you can only select one of these and so I set mine to GSM ALL and left the others alone. This worked for me, so I thought I'd mention it.
Now that you've manually rebooted after following the directions, you still have to edit your build prop to allow you to edit the apn settings. To edit your build.prop you must be rooted so root with CF auto-root http://autoroot.chainfire.eu/ download the proper one for the galaxy s4.
It's just an odin flash, so enter download mode
load up odin 3.x
hit the pda button and select the cf auto root tar
hit start.
After rooting I found that one time I had to do some of the service mode settings again and one time I did not, so I mention it here even though I think I had to because of some other error I had made at the time.
Go to play store and download build.prop editor and APN settings Shortcut
Load the build.prop editor and add these two lines to the end of the file
ril.sales_code=LOL
ro.csc.sales_code=LOL
Now reboot manually
add the apn settings widgit to the main screen and open it
click on menu and add an apn
Enter the apn settings for your carrier here. They're all different,(the carriers) but you can find them(the apn settings) easily with google, since they (carriers) all post their apn settings on their webpages.
Don't forget to save the apn settings.
Now select it.
Now reboot, since it couldn't hurt, right?
If you've done everything right you should now have an domestic and international unlocked Sprint galaxy s4. Enjoy.
I suppose you could now reflash the new modem back onto the phone, but I don't have firsthand knowledge whether this works or not- I've only read that others have said that it works. Remember, ONLY FLASH THE MODEM, the rest isn't necessary and will probably knox you all up
All I did was list these things- credit goes to all those who were linked in the above post. Thanks for all you do.
On stock 4.3 and higher you can go into settings and change your APN, so there's no reason to root and mess around with build.prop editor.
Every time i try this i cant get my wifi back up when i flash back to the nae modem. If i could get pass that then I'll definetly be do that.

I have read that the modem itself cannot be downgraded. You can run older android versions and such on the newer modems, but the modem itself cannot be rolled back. I believe it has been like that since MJA.
You can downgrade modem, but can not downgrade bootloader (aboot)

I completed both the international & domestic unlock. I believe I was successful in each. I have a T-Mo sim card inserted but am not getting a mobile data connection. I do have 2 bars of service though. So I have gotten past the red X on the bars.
I am on 4.4.2 with the MDC modem. I did not do the build.prop stuff, instead opted to just access the APN's from the default menu.
A few things in my menu were different than the OP (probably because of 4.4) such as:
I dont have any roaming menu options
I dont have WCDMA.. just CDMA and LTE/CDMA. I currently have it set to LTE/CDMA
In my APN edit info there was not a place to put in MMS protocol: WAP 2.0
Also under About Device "my phone number" is wrong.
Am I missing something to get this t-mo working?

You didn't unlock it. If you were on NAE modem while unlocking then you failed miserably because you're not able to get into the most important part of the unlock...The service menu. If you did indeed downgrade the modem then you're going to need to follow the domestic unlock guide again. If it's showing CDMA/LTE you didn't do it right. It should show WCDMA only and WCDMA only isn't an option you can just select. It gets put there by the service menu.

I said I wasn't on NAE, I am on MDC. I did get into the service menu. I did everything in the process without issues. My service menu did NOT have a WCDMA only option. It had LTE/WCDMA and that's what i chose. I just went to the t-mobile store and they verified my APN settings were correct. I am unsure of what to do at this point other than just start all over and do it again.
Anyone else?

I apologize. Long work day. Follow the guide. When it comes to where it says select LTE, GSM, and WCDMA all, ONLY select WCDMA all. At no point should you see your Sprint phone number in about phone. Also you should see IMEISV in about phone as well if you've successfully unlocked it. It'll help if you posted the steps you've gone through. Otherwise were just shooting in the dark.

From the S5 thread and now here we meet again in a revisit in time. Since I know you own and understand the L720 more than I do, could you please explain to me if this will work on a 4.4.2 NAE rom? I picked up an L720 (bad esn) for $100 and its in pretty great shape. Now I'm looking to unlock it but my experience with Samsung devices are very mild. It came on CM10.2 (4.3.1) and ive slowly caught up with things. So i understand that sadly there is no such thing as downgrading from KK to JB, I was trying to get it stock on JB with no cigar. Elsewhere I found out that you must flash something identical or above. So im planning on flashing an NAE 4.4.2 stock rom (custom recovery flashable) I found in order to attempt to unlock it cause I can't seem to find a 4.4.1 as mentioned in the OP. I flashed the MDC modem and it stuck, so with little knowledge I am assuming that it will stick once I flash this new rom? Correct me if I am going down the wrong path...
EDIT: Great nobody ever mentioned anywhere that the software used on the international unlock is for 64bit only...

The software works on 32 bit too. Actually you can even perform the international unlock WITHOUT the tool if you know how to use QPST or DFS. Anyway...
Flash full NAE. Flash MDC modem. International unlock. Domestic unlock. Win.

Must be an issue with my PC, nothing new...
And I know a thing or two about QPST. I still have it on my computer from a few days ago from when I was fixing a horribly corrupted IMEI on a G2 a friend of mine bought. I'm assuming I have to use a NAE stock tar with ODIN, because I tried a ROM of it and it lags and stays on black screens for seconds and WiFi doesn't work im sure because of the fact that the modem is older than the rom. Let's see if that works cause ive been trying to flash back to any stock ROM since I got this thing yesterday.
(Almost there...)
NEVER MIND. Got the international part working perfectly by using the Windows Vista partition on my PC. Now reading on, OP mentions that next the domestic unlock must be done, a link is provided there to another thread with domestic unlock instructions. Heres the question. The OP in the other thread mentions to hop onto 4.3 via odin. How can I get to 4.3 to domestic unlock if Odin doesnt let you downgrade?

Read the specifics. You cannot downgrade boot loaders but you CAN downgrade modems.
Unlock just requires MDC or MDL modem.

Yeah I remember that part but from what I was understanding, that's for the international. Domestic requires messing with some files and done. I already got the international part by tossing CM10.2 along with the MDC modem because stock Touch wiz would cause lag and reboots and non working wifi I'm assuming because of the mismatched combo. I DO know that obviously we need a TW rom in order to unlock domestic.
EDIT: I finally got the hint and got it to work. But I only get Edge instead of 3G. Does anyone know where I may be able to find that T-Mobile rom made for us? When I Google it I end up on the T-Mobile side.

I downgraded from latest bootloader on 4.4.2 or was it 4.4.4? Down to 4.3 which is the absolute best ROM version for service mode menu. It got me into service mode menu on first try by selecting menu back and input of 1. What I did was first install cf autoroot to root then cwm and used cwm to flash the 4.3 stock deodexed, I only used Odin for flashing modem. Odin gave me an error when flashing modem and phone got stuck in kies mode but i got it to get unstuck by just flashing cf auto root again to make the kies mode error thingy think odin flash has went well. Turns out MDC modem flashed despite odin error.
Anyways. While on 4.3 and MDC modem I noticed no WiFi but I had sound. I followed the international and domestic unlock instructions and WiFi was still broke when I got back to 4.4.2 but I had unlock and sim card working and got bars. I am on aosp 4.4.4 now and the nae modem I finally flashed works well with this ROM but soon I gotta go to touchwhiz 4.4.4. If I go to 4.4.4 touch whiz WiFi and all else will work fine just as they do on slim aosp . 4.4.2 touchwhiz is still not giving me wifi on NAE modem. Update NAE 4.4.2 stock deodexed rooted rom i got from xda android thread did the trick and all works well now. All is perfectly working after i flashed it in cwm.
For aosp lovers. aosp requires additional things to do so aosp dialer can make and receive calls fine. I can call but there are issues until I follow another guide on xda that resolves those issues on aosp ROMs using sprint s4.

If you see system slow, no wifi, no audio and lockscreen being nearly impossible to unlock, its due to you being on a higher ROM than the modem was meant for.
I just got the note 4, rooted it and flashed a rom, however I have no service it shows. I am using Metropcs and it shows "no service" no matter what I try, if I take the sim card out then it will show the logo that there is no sim card inserted so it does recognize it at least. The sim card and service works fine in my other phones but I can't figure out how to get it to work on here.
Check ESN on Swappa??

What is the model number? And in "settings/ about device/status" does your number, IMEI, Network state or network show up?

The model number is the N910T3 version, it does show my number, it lists the IMEI and for all of the network state related stuff it lists it as "UNKNOWN."
Are you still on TEKXodus? If you came from an older version ie..4.4.4 or whatever then I'd suggest Odin flashing 5.1.1 stock, see if you get service then try flashing the custom rom again. Might be a mismatch in baseband and all that. Open dialer and punch in these numbers *#12580*369#*and make sure everything matches. Also run thru the thread you found the rom and make sure you flashed everything suggested.

I tried Odin flashing the stock 5.1.1 firmware and had no luck, also used Samsung Kies firmware to try and go back to stock as well just in case that would solve anything and I have no luck. It just shows " (No Service) " When I look in the status bar, and it still says it isn't registered.
And when you open dialer and input this *#12580*369# everything matches?

I'll go ahead and attach an image as well to show. Yes everything seems to match up when I input that in the dialer.
Sorry I wasn't doubting your word lol, honestly I'm kinda stumped as well, almost seems to be network locked. Is it a Metro branded phone or Tmobile? I wouldn't think that would matter. Wish I was more help fella

It is a T-Mobile brand phone, which I figured wouldn't matter much anyways, I've owned a few T-Mobile phones in the past and have had no issues using Metro Pcs even if the phone was locked because T-Mobile does own them. That's perfectly fine, thank you for giving some suggestions anyways that I hadn't thought of.
The Apn checks out? In settings?
U could also try flashing a data fix for the international roms. Maybe last resort try a new sim
Like the guy above said have you checked apn settings? You could also try in the mobile setting where it says Network Operators and then Search Now and let it search. Choose Tmobile if it pops up or if MetroPCS pops up choose that. If you need MetroPCS apns I have them since I'm on MetroPCS. Let me know if you've fixed this because I haven't rooted yet and plan to root and install Tekxodus rom but if this is a problem then I'll just stick with stock unroot. I have the N910T tmobile brand if that matters
APN settings have really nothing to do with his dilemma, my question would be this for the OP. Please check if the IMEI number matches the one that's on the back of the phone under the battery. I have a work around but i need to verify.
I went through the same problem coming from TekXodus rom. I tried everything and no luck. Flashed 5.1.1 stock and called tmobile about it. after their tech guy didnt know anything else i could try they sent me a replacement.
And now here I am again
I also flashed tekxodus from my wifes 4.4 phone. Now no sim card issue. Same as op.
Edit: flashed the correct baseband. All good over here.
