Okay so i have the T-Mobile Galaxy s3. It has been rooted for a while with zero problems. I got tired of the older android on it and decided to install a rom. I installed Cyanogenmod 13.0-20151208-unofficial-d2tmo running android 6.0.1. When i first got it all booted and loaded with gapps, i noticed that it recognized my sim and that i had a signal but i couldn't use any LTE or just all around data. basically i couldn't go online (in case i just didn't explain that well enough. Phone service is a mystery to me). I did some searching online and found a lot of people saying that i needed to update my baseband. i found a baseband for my model (T999) and tried to flash it in TWRM. Once i rebooted, it said "No SIM card - No service." in the upper left-hand side. i have tried flashing multiple different basebands the same way with no luck. i tried backing up my EFS folder and the restoring it because someone said to do that and that just... just no... it didn't do anything. even Odin 3 said it was a "FAIL!". So here i am with this android equivalent to an Ipod and i hate this. Everything else in this ROM works perfectly aside from this but this is a super big problem. PLEASE HELP!!!! A phone isn't a phone if you cant even send a text.
Did you update the phone's bootloader and modem to the latest version before flashing CM?

I have the same problem, I am looking how to fixing it. If you find a way, please PM me.
A few days ago I purchased a Verizon Galaxy Note 2 off of Craigslist. When the guy brought it to me I was able to test the phone with my 4G chip. It was able to make calls and access the internet. Once I got home I noticed that the phone would constantly go into a Demo mode and erase any changes that I had made to the phone. Instead of calling the guy that sold me the phone I decided I would just go ahead and root it.
The first attempt at rooting the phone ended up as a disaster. It was constantly rebooting after the splash screen. I later found that this was an easy fix. I had decided to "Nand erase All" and then it would not even boot. I finally found a Root66, the phone came up fine but I had no connection to Verizon with or without the 4g chip. I looked through the phone settings and found that under the "Baseband Version" it said unknown. Since then I have tried flashing in with other roms. Right now its flashed with KIES_HOME_I605VRAMC3_I605VZWAMC3_1098177_REV04_user_low_ship.tar.
Its still says the Baseband Version is Unknown and the only thing that works is the wifi.
Please HELP!!!

I think your EFS has been messed up..what you should do is backup your current EFS even though it's highly damaged.... find a way to recover your EFS search on XDA ..EFS repair or EFS recover if all fails flash a genuine stock ROM and retry the repair or rebuild of the EFS... also as it's a demo phone...there could be other complications..I'm not sure.
seems like damaged efs.. if you had backed up the efs,just try flashing older modem. but if you never back up the efs,it will be very difficult..i suggest you to read all the threads about restoring efs and hope you can fix it.

http://forum.xda-developers.com/showthread.php?t=2392632 This thread should definitely help you. There are all possible ways you can restore your EFS done by @tamirda . I just got my baseband version back on my Note II International GT 7100.
Just got Samsung Nexus Korean maguro variant yakju with 4.1 installed and with Baseband: UGKL1 and my network is Warid Tel - Pakistan. I used my local sim in as well and it was working fine. Today I tried to use custom 4.3.1 in it and so I done these steps:
Downloaded Nexus Root Toolkit, Android SDK, Latest Nexus drivers and all pre-requisites before starting. Now I first started to unlock my Bootloader with matching requirements as the tool already do this. Then flashed cwm touch recovery and applied root. I tool backup of my stock rom via cwm and then wipe all and installed liquidsmooth 2.7 which is jb 4.3.1 and it worked like a charm. What i noticed afterwards that the rom is reading my carrier details correctly but also showing Emergency call only warning as well. I tried Edge as well and it was wokring normally but when i tried to dial a call and tried to send txt it showed me Mobile network not avaialable. Then I tried all latest radio basebands on it, tried all settings SMSC and normal troubleshoots but couldn't get complete carrier support. Then I restored my default stock rom via cmw and boom no issues like it should be. Now my question is did I missed something for it? or am I flashing wrong basebands? or somthing else? After too many hours i felt that I cannot go further from here. I am attaching my screenshots. Please if anyone can tell me or guide me I will be very thankful to him as I haven't tried my phone yet, just got it. I had HTC evo 3d and its setup of everything never got me stucked like this.
Anybody up for help kindly

Hello fellow xda members. Well after searching for a solution for my for nearly a week now i figure i should post the question to see if i can get an answer. I did search around before hand and tried many solutions but to no avail.
Background, I have a sgh-t999 that's apparently unlocked since I've been using a fido sim card in it for several months now. when ever I'm running cm 10.1, I have full network access, texts, mms, 3g data, etc.Note: d2mtr is flashed to my phone and my model number gets changed to sch-r530, baseband: t999vvllh2.
After flashing to cm 10.2 RC1. d2mtr. I get stuck on the metroPcs network with out any way to manually switch network operators because the option in mobile networks is greyed out. Everything seems to work fine in terms of calls but besides being able to receive texts messages i can't send them. The signal bar seems to be empty or greyed out yet it still picks up 3g data. I've vigorously checked my apn settings to no avail. deleted the voice+ apk since I'm not in the US being in Canada and i'm all out of options right now. If i restore back to my previous backup ,everything works fine and i did check to see if I loose my imei number after flash.
I previously tried flashing d2tmo to my device but to no avail, assert errors. It would greatly be appreciated to get a response and thank you in advance for any help.
Edit: It's a sgh-t999v as printed behind the battery. I followed this guide http://forum.xda-developers.com/showthread.php?t=1775616 hence the reason why I'm coming from ICS. Looks like I'll have to reflash using ODIN which i was trying to avoid out of fear of bricking but it seems like my only option now.

Might not be the right ROM for your phone. Or it could be buggy. I've messed around with a few and finally found a great one that seems to be working well for me. I have the d2ltetmo. I'm running Liquid Smooth ROM with 4.2.2 and TWRP 2500 recovery. The ROM roots your phone as well. Any questions feel free to ask. Hope I can help!:cyclops:
I wouldn't flash D2MTR Rom to D2TMO. Too many differing things. There's a CM for D2TMO too.
Are you sure that's a t999? The baseband looks like the one for the t999v.. And it also looks like you might be on ICS firmware.. What I suggest you do is check the model number of your phone to be sure what model you have, after that update to 4.1.1 or 4.1.2 via Odin but make sure its the firmware for your model. After this flash your custom recovery, and then try flashing cm10.1 for d2tmo.. If your device bootloops after you Odin, enter recovery and do a factory reset.
Edit: check the model number by removing the battery and it will say at the back of the phone.. And the firmwares to flash in odin are in the development thread

Well after a long process of flashing stock jb then finding a proper method of flashing cwm since i had difficulties with fastboot and went with the dd if-of method using the terminal emulator. I am finally on a stable cm 10.2 rom, d2tmo, where everything seems to be working and intact. Thanks for the advice now i have the long process of restoring my apps and data and what not with titanium backup.
Ok so i got the phone is stock form with android 5.1 and a few bugs common to this phone( screen flicker and poor wifi speed). I read more than a few forum posts that said flashing the rom to various other roms would fix it and this wasn't my first modded phone so i did. I am not too sure these flashes took as android looked and acted the same as well as had some of the elephone software. It did however screw up the phones imei. after a google search i reset the imei. I no longer have the invalid imei message but now i have a big NO SERVICE message. This is the us market phone. I really hope you cant somehow change the frequncy bands by flashing the rom. any help would be awesome.
Ps. the screen still flashes.
edit: ok tookjfer671's advice and flashed the us rom. it killed the imei (again) so i reset the imei. now somehow the imei numbers got on the wrong sim cards. They are backwards. will this affect anything ? they wont reset at all.
Edit 2 I guess you can mark this one as solved. The reflash with the us ROM worked but the backlight still flickers. Not a launcher issue the entire screen goes dark and its random.

Yup, I believe the US version B doesn't have any other alternative custom roms to flash...although you can root. Version A (Asia/Europe) regions have a whole lot of roms to choose from...it would've been nice if we could flash those as well and keep the baseband out of it so we don't lose network connections.
Anyways...I flashed as well a version A rom and found myself with a no connection to my network (everything else worked fine), flashed the link above and got device back to full working order. Hope it helps you out.

i'll give it one more shot. btw did you use flashtools or recovery?
Sorry for late reply...I was rooted with the A version and on TWRP recovery, flashed stock recovery then flashed B version and now on CWM recovery. All using flashtools.
