Sorry on the noob question but, I just bought a HTC vivid from a guy and he said the phone was rooted. How can I unroot it or how can I fix it so my att sim card works. The guy said it was unlocked and on t mobile so maybe the setting are messed up. It's on Android version 2.3.4 and htc sense version 3.0.
Same here
in the same boat except I am the one that unlocked the SIM. I used it with T-Mobile and am now trying to sell it. I met a customer at an AT&T store & tried multiple SIM's, but none of them worked. We reset factory reset acouple of times, but that didn't change anything. The weird thing is that when you put an AT&T SIM in the Mobile Network settings are grayed out. Take the card out and the settings are able to be selected.
Sorry to piggyback off this, but Idid want to add that I don't think it has much to do with the current version of Android you're running.
Under mobile data settings, APNs, push menu, restore defaults.

Resetting to default APN settings doesn't change anything in my case. After a factory reset there are no APN settings anyway. The issue I have is when an AT&T SIM card is installed, everything under Mobile Settings is grayed out. You can't select a network to register with and you can't add AT&T's APN or even reset for that matter.
Should I look into doing a hard reboot? Or does anyone know the codes to dial to get access to the radio (ex. ##12345##)? I read through the first couple of posts in the threads linked, but they don't really address the SIM issue. Sure, I saw the notes on APN's, but I don't think this is what is the base of my issue.
Thanks a lot for the links. I actually got it working last night, I changed the apn setting to say phone and it started to work. But I still want to return it to stock to install ICS. On the second link I use step six right to unroot it? And which ruu do I need, because I see like three for Cingular. Thanks.

In the SUPERGUIDE start at the very top, first paragraph. You need the RUU that came on your device If yours came with Gingerbread I would guess this one,but it is only a guess. .Download RUU_Holiday_Cingular_US_1.63.502.4_Radio_1.11.1020.03_30.77.551061.02L_release_221238_signed.exe from FileFactory.com
Thanks. But how do I know what software my came with.
Edit: yup it should be that one.
Is their any other link for the RUU download, it keeps failing for me.

Just a thought, what would happen if I update my phone using the update option on the phone? Would it brick it or would it work?
Not sure on that but if it where stock it may ask you to upgrade to ics but I don't know.for sure .
Because I want to return it to stock to then install ics.

hi all
i thought i would attempt to flash my samsung s with the new beta froyo update.
i followed this guys tutorial.
( cant link to it sorry its the noobs guide with detailed instructions through kies and odin)
i used the odin approach
i managed to root the phone.
on reboot it asked for an unlock code (o2 uk) so i went on to try and follow the steps about unlocking it. which neither worked all the way through the steps.
on reboot it appears to have signal and in the about section it says i am onnected to the o2 network but when i try to make a call is says "data network not available with an ok button, which when pressed will return you to the ome screen.
any help would be greatly appreciated thanks
Almost the same problem,
installed 2.2 update successfully, the phone worked for like 3-4 days very well and after that today i discovered "Emergency calls only"
so the question now is did i bought phone which later was reported stolen? or somehow i broke it?
Anyone have any idea?
hmmm, I have the same problem! In the status menu, the number is shown, but the network, says "unknown"
Hi! I have this exact same problem except I was unlocking my phone using this tutorial:
http://forum.xda-developers.com/showthread.php?t=906255
But I didn't back up my Efs folder, now my phone is unlocked but when I put a sim card in it I have very little network and when I try to make a call I get " NO DATA NETWORK AVAILABLE".
I've tried everything but I don't know what to do!
I was thinking of two ways to fix it:
1. Reinstall froyo (not quite sure how using the samsung software as my laptop oesn't recognised the phone as a pone)
2. Downgrade to, get unlock code using market app and then upgrade to froyo again.
I know I messed up but now I really need to fix this.
Can someone PLEASE PLEASE help me out.

might need to change the modem in odin i think. just heard about it
did u try restarting the phone... just a wild guess...
I had the same issue before and was puzzled. Its actually a very simple solution:
1. Re-lock your phone, search through xda there is a code you have to enter
2. Unlock your phone
All done! Surprisingly easy
Try the Odin method in block 2 back to Eclair if ok then upgrade to Froyo .
http://forum.xda-developers.com/showthread.php?t=818556
However your non connection might be due to not flashing a firmware with your network settings in which case manual settings of APN .
If your IMEI has changed due to flashing and you did not back up your EFS folder then little hope but do a google / search of XDA as some have reported success .
jje
Emergency calls only
I had a custom rom that was giving that to me too. I think it means that you can access a network different from your sim (because usually emerg calls can be made from any phone I think?).
I'd try and find a rom that is optimized for your carrier or at least a modem file from a stock rom that is for your carrier. You may also need to reselect the APN settings (or enter them for your carrier). Its under settings/wireless and network/Mobile networks/access point names (use the menu button to add an APN).
you could also try re downloading and flashing the rom to make sure that is the issue. Mine said it installed OK but never booted up, redownloaded and reflashed and then it was fine but the install screens looked identical.

Hi! Thank you so much for everyone's replies!
My IMEI isn't changed and someone helped me check my efs files and they are all ok. I'm going to try and reflash froyo through the samsung software to see if the network lock comes back and then try to unlock again. For this I'm going to unroot the phone and follow samsungs' instructions.
I'm afraid to relock the phone as there are reports that say it completely messes everything up!
But I'll keep you guys posted! Wish me luck!!!!
PS. Any other suggestions are more than welcome!
So, a quick update on my situation.
I uninstalled busybox and unrooted my phone using the oneclick root tool.
Did a factory format and, surprise surprise, my phone now works perfectly!
Apart from the fact that it doesn't connect to kies, but that's a whole another issue!
Tank you so much to all of you who answered my cry for help!

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?
Thank you.

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 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

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?

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.

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.

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.

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.

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.

Hi All ,
My apologies if there is a solution to my problem in another thread. I have spent countless hours looking for a way to unroot my Sprint HTC One because the Sprint network can't seem to activate it until I do. Or I need to figure out a way to force the Sprint network to accept my MDN and MSID which can "sometimes" be problematic with rooted devices. It might be easier to just unroot and see if that helps getting the phone to properly activate.
Other than the network connectivity issues, the phone is fully functional. Just cant make calls or send texts.
I am running this ROM based on benny's system dump: http://forum.xda-developers.com/showthread.php?t=2467607 so my device information is:
Android version - 4.3
Sense version - 5.0
Software version - benny's 4.3
Kernel version - [email protected] #1 SMP PREEMPT
Baseband version - 1.00.20.0913_3
Build number - 3.04.651.2 CL251863 release-keys
I've tried everything I can think of to get my device unrooted, but none of the RUUs work due to being on hboot 1.55 s-on or having an older firmware version (1.29.xx or 1.39.xx.)
Is there any method I can use to get completely back to un-rooted stock rom with, relocked boot loader (know how to do that part), stock recovery, etc?
I've looked at so many different threads and google searches and all say you need to be s-off and run RUUs of versions that will either cause my touch screen to not work or worse. If anyone can help me it would be amazing and I would be much obliged.

Ah yes! The 3.04 version wasn't available the last time I read that post! I can confirm that the other that using the 1.29 and 1.31 versions caused serious issues for me and my phone.

There is no RUU for 3.04 yet ( that I know of)...

Did you ever find a way to resolve this issue? Also did this start after flashing Cyanogenmod? I have the exact same issue and it seems I have exhausted all available resources. Currently have the following setup:
Android version - 4.3
Sense version - 5.0
Software version - 3.04.651.2
Kernel version - [email protected] #1 SMP PREEMPT
Baseband version - 1.00.20.0913_3
Build number - 3.04.651.2 CL251863 release-keys
Noticed that the phone is unable to update PRL correctly. Version will switch from 00000 to 1 to 55016. I am also unable to commit changes to any EPST settings (which is the first thing sprint tried to do). MDN and MSID both currently say 'no' and I can't update.
I'm having the exact same issue with everything working fine but no calls/texts.
I flashed the Guru reset for 3.04 but still no calls/text.
Any other solutions?

Try the following:
Full wipe. Flash the newest stable CM.
Go into Settings > More... (under Wireless & Networks) > Mobile networks > CDMA subscription:
Confirm the following settings:
Network mode = LTE/CDMA/EvDo
CDMA subscription = NV
After you confirm these settings, switch the network mode to CDMA/EvDo only and then back to LTE/CDMA/EvDO.and give it a minute or so, you should see 3G/Phone availability come back. You can test this by dialing a number. You should be able to make a call, or at least get the default Sprint "device is not activated" recording. After confirming this, you can do another wipe and flash back to a stock ROM. You should now have mobile network connectivity back. You may need to Activate the phone again and update the profile/PRL to get back to 100%.

Hmm. That's pretty much the issue that I had except 4G/Wifi was working and 3G/Call/Text didnt seem to be. You might try switching the CDMA mode to SIM and then back to NV to make sure the setting takes. I know CM can be really finicky with network changes.

no luck
At this point I have not had any luck solving this issue. I used Guru's reset tool as well and believe the problem is the radio firmware. I spent a good deal of time on the phone with Sprint support and with a surprisingly competent technician in the store. He tried to work with multiple different systems they have available to get the phone to recognize the Sprint towers with no success.
He said that the phone just isn't recognizing them in any way and commented that a phone that isn't activated will still show bars of service because the phone gets the signals from nearby towers, but just doesn't know what to do with the signal until activated. In my case, all I see is the "X" above the signal bar graphic.
If you're experiencing the same issue as me, there is nothing Sprint can do to make the phone recognize their towers based on the conversations I've had. I saw my options as:
1. Wait for an RUU to come out or something like that
2. Try out different ROMs - jjmckaskie suggested the newest CM, but I would think others might be worth trying as well. Basically anything that uses different radio firmware
3. Get a new phone - This is the option I've gone with. Since my phone is running a stock ROM and the guy at Best Buy where my insurance is from, didn't check the bootloader (would have said "tampered" and "unlocked"), he assumed I never voided my warranty and sent out for a refurb. This may not work if your insurance is through Sprint though. I'm not sure how thorough they are.

As a last resort you could also try the hard reset code from your dialer by entering ##72786# . You will need to be on a stock rom. You will also need your MSL code (you can usually get this from Sprint support). This will reset EVERYTHING so be mindful. It will also force a hands free activation/Profile/PRL update after the phone reboots which is sometimes useful.

I still took it to Sprint just to see and they fixed it. Downside is my GPS and LTE is messed up again (Me trying to fix those things is the reason all this happened in the first place) but I'd rather not have GPS than not have phone capabilities on my phone (And LTE in Los Angeles is garbage anyway). I think I'm gonna leave my phone alone for a while tho, lol.

Yup. I actually dont remember if it does a full wipe, or just forces an activation/profile/PRL update. But either way it's worth a shot.

Sounds like you solved your issue, but for anyone else having trouble....
I re-tried GURU's reset and it worked. The first time I downloaded it over the 4G network. I also downloaded the OTA over the 4G network. My radio has been giving me fits ever since. Finally, I downloaded GURU's reset over WIFI, then made sure the OTA downloaded over WIFI, and my phone is like new again! No radio issues, everything is perfect. Hope this helps some people...
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.

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.

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.
