So my friend just gave me his old Tmobile S4 SGH-M919 running Android 4.4.4 Baseband M919UVUFOK3. The problem is that Wifi and bluetooth will not turn on. I've tried all the basic stuff like taking the battery out and wiping the phone. I even tried flashing earlier 4.4.4 versions onto it and nada. I read something about flashing a modem.bin file onto it, but every thread i've found doesnt have the file link anymore. Any help would be greatly appreciated. Oh I do have a Mac Address but no sim card.
To those who might be reading, I popped my battery out with phone on while unrooted. The wifi came back after reboot. Then I rooted. Now the Wifi is doing the same problem.

OK guys i'm a complete noob here at XDA (registered yesterday) but i'm getting really desperate and confused and since i've seen XDA is such a great community i thought i'd give it a shot...
My GSII had been running BeastMOD ROM II v3.0 for about a month now and it worked like a dream but about 3 days ago i turned off my phone and then turned it back on a minute later and I HAD NO NETWORK!! Now, that i recall i didn't do anything to cause this. I called t-mobile and went through all their troubleshooting, no luck. I flashed BeastMOD ROM II v4.2, no luck. Re-flashed BMOD 3.0, no luck. I noticed i don't get ping to my network, I have no IMEI number(i get null/null), and no baseband version(unknown). I'm really worried and hopefully you guys can help me some suggestions ASAP as i haven't had network in three days.
restore a back up of your stock if you still have it.
and this will only get me back to stock and not undo root or will it? will try
Here's what happens. I try to do my first stock ROM restore and it says
"Checking MD5 sums...
MD5 mismatch!" <--Whats wrong? I'm currently doing a restore on a backup three hours after that one which i'm not sure which one it is (maybe the first backup after i installed BMOD 3.0) but hopefully it will do something.

Hey thanx for that last link but the freakin person that made that method just bailed on me after his method screwed with my phone. I have stock now but i have a problem where my phone keeps rebooting until it gets network and even after it finds network and gets its IMEI and Baseband version back, that "fix" doesn't let me use data and for some actions the phone says the SIM card is not ready or available. and when i turn off the phone and back on it keeps rebooting until it finds network like i said. I don't know what the EFS is but that could be something that is making the phone malfunction. Please! Someone help!
i had almost the same problem.
My IMEI is still there, but it just won't connect to any network! All of a sudden, I woke up and it wont connect!
I'm getting a replacement sent to me from tmobile. weird.
I apologize if i am not as clear in this post as I need to be. My dad tried to root his note 2 sgh i371 using odin but said that once he did this, he was unable to access the internet outside of connecting to wifi, he could not get any cellular data. Because of this issue, he tried to then un-root his phone by flashing 4.1.2 stock rom. Unfortunately, the issue of not being able to get cellular data persists. In his frustration, my dad bought a note 3 and gave his note 2 to me saying that if I could fix it I could keep it. This is my first android and I would like to make it my primary phone if possible. what I would like to simply to reset the phone to factory default settings by flashing the latest stock rom for the phone. I have Odin, I was hoping that someone could tell me where I could get the latest stock rom and, if they believed that flashing it would fix the cellular data issue. I do not believe my dad made a backup at all. Thank you in advance.
Hello, I used to own a GS3 and had it rooted and everything just fine, but I sold it when I broke the screen. I recently purchased a used one off Ebay and want to get back root and custom ROM. The seller had the firmware updated to 4.4.2 stock and of course it is bloated to hell. I managed to get the root installed, however I flashed a new rom and modem and now have no network connection. I have tried modems LK3, MJ2, and MJB and none have worked. Also, somewhere down the line I managed to break the wifi, as when I try to turn on wifi it instantly switches off.
I remember it being very easy to root back when the device first came out, I was on a Galaxy Nexus previously and everything. Another thing to note, once I got the root installed I made a backup in cwm and even restoring this backup I have broken modem and wifi. How ****ed is my phone?
EDIT: I managed to find the elusive NE4 modem that was not in the "all modems" thread. This fixed my issue. Feel free to close thread mods
Closed at OP request.
Hello,
I recently got a galaxy nexus and noticed that the wifi and data radios were not working correctly. The device was already rooted so I decided to unroot the phone and reflash the radios following this guide: http://forum.xda-developers.com/galaxy-nexus/general/how-to-return-to-stock-galaxy-nexus-t1626895. After doing this I noticed the same problem and I'm not sure what to do. It seemed everything went fine and looked normal as I was doing it. I'm wondering if there was something I missed. Anyway thanks for the help!
Oh as for the wifi issue. Everytime I connect to a wifi network, I get an authentication error. No I can't access router settings because I'm in college. As for data, well I don't get anything when I put in my sim card.
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?
