Alright got a question and I've tried everything I can think of here. I was running santod's tiKtaK and wanted to give his new 4.4.2 ROM a try. I installed it using the latest TWRP. TWRP restarted on me once but reading though the forum I should just try to install it again which I did. It installed and I got it to boot up. The only thing is now I have no Mobile Network signal or anything. Everything else works fine. I have no network, no signal strength, no phone number or IMEI listed in the phone. I have tried pulling the SIM Card and rebooting I have tried *#*#4636#*#* to change settings and all a no go. The thing is if I flash back to my other rom everything is there and working. Any suggestions?
I am having the same issue. Did you find any resolution? Or can anyone provide some insight?

I had a buddy at work who flashed CleanROM to his phone today at work, he had stopped by my desk and asked me why the phone wouldn't detect his service. I looked and the phone was showing that their was no radio/service. I used Clockwork to flash the ROM again using factory wipe as well as clearing the cache and still had the same issue. Is their a way that I can just install the default radio driver to the phone? I had him try to flash the STOCK ATT ROM for the note 2 back to his phone and still no luck. Gives a message saying that it cant detect the sim? or something to that extent. Any help would be great, thanks ahead of time.
Edit: I also wanted to add that the SIM was working fine before the phone was flashed with CLEAN ROM. There after it no longer worked.

Dunno about your predicament really but in the cleanRom 1st post there is a link to Scotts website where there is a newer modem from the newest ATT OTA update you could try to flash and see if that helps at all.Also I don't know if you tried to take out the sim and put it back in(while the phone is off of course). You would be suprized how many times that has solved radio issues before because sometimes a phone gets bumped just right.In this phone the sim card slot is spring loaded like the micro sd slots.Just a couple ideas for ya.
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.
Hi there,
I've got an HTC One M8, on the T-Mobile Network. I recently unlocked and rooted my phone. I downloaded the Paranoid Android beta ROM and installed it along with gapps. All went smoothly and booted up fine. However, I noticed my phone wasn't connecting to LTE. All I could do was make phone calls. I tried flashing the ROM again, same issue. I then tried the Cyanogenmod ROM and also had the same issue, so I finally restored my phone's nandroid backup so I'm all good again.
But I'm curious what the issue might be. I also tried taking out and putting back in my SIM card etc. Is there something I'm missing that I need to do?

OKay, I was able to resolve this issue on my own. I changed my APN setting to utilize IPv6 and it's been running just fine. Go figure.
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?

Have u rooted. Flashed a rom? Is it network unlocked if not on orig device carrier? And if just pirchased are u sure its not black listed?
it is not black listed.
It all began when it started on all the time.
Now it has not started on all the time at 24 hours now.
And I flashed a ROM.
After that, you will not signal more than a few seconds, then you can not register on the network.
Have tried with APN that I know works, but not on this phone can only use wifi.Jag checked with the operator and they have no problems.
Have tried with different SIM cards without result.
my simcard worked with the phone before it started on all the time and I installed a ROM tried olkia rum with the same result.

May have flashed a rom with a incompatible modem. Try using flashtool lgup and going back 100% stock. But be sure to make sure ure not downgrading to a incompatible version or brick could result. Find out what version qfuse ure bootloader is and find stock rom to match.
