SM-T520 Modem - Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble

In trying to fix issues I had with TWRP 3.1.1 I screwed everything up with my tablet. Ended up being a bad USB cable, but in the process of trying to get it running again I corrupted my modem. I have working Odin and TWRP but no WiFi.
Can't seem to find a stock firmware that includes a modem.bin. Anyone have any ideas?

Edit - modem was fine, at least after a stock firmware flash, was probably ok all along. Google setup is broken and tries to connect before WiFi setup. Just skip through, setup WiFi and go back to set up and restore.

Network Data Hosed

I've gotten my phone into a state where I see signal bars, I can make calls and send texts, but no LTE or H+ is displayed and if I try do anything involving the internet it says there's no network connection. Wifi works just fine.
Here's how I got into the predicament. I should have learned my lesson from last time I flashed a Verizon ROM, but I didn't, and I flashed SkyNote RC9Z-3.9.1. Data works just fine in THAT ROM, but any subsequent ROM flashed after that... the network data is completely HOSED. I've tried enabling and disabling network data in settings. I've tried flashing the Devil kernel. I've tried restoring several different ROMS from nandroid backups. All restore fine and all have completely non-working network data. Last time I ran into this I had to flash the stock image in Odin to fiz the issue. This time however, that didn't work. The images flashed successfully, but upon reboot all I got was a a welcome screen bootloop of the samsung swirly logo and the T-Mobile logo.
I'm guessing this has something to do with the 4.3 bootloader? I'm downloading T889UVUCMK7_T889TMBCMK7_TMB.zip from SamMobile site and boy is it taking FOREVER! 7 hours left on the download. My thinking thoug is that If I unzip this new 4.3 firmware and flash it with Odin (or Kies if I absolutle have to) my device will start behaving again, and Network data will work, and I can go about ROM flashing and hopping again (though I'm gonna stay away from those Verizon ROMs let met tell you!).
Does anyone else have any other suggestions on what I can do to get my data back or to patch my bootloader to the 4.3 version? I was looking at this thread and wondering if it's safe to follow this procedure for patching once I have installed the 4.3 stock image:

No WiFi - EFS folder is empty

Hello everyone. Looking for some help. I suddenly lost the ability to use WiFi. I have 4g and cell service. When I try to turn on WiFi my phone reboots. After the reboot I get a message that the phone is in factory mode. I opened my EFS folder to make edits but it is empty. Can anybody help?
EDIT: I'm currently on 4.4.4 NH7 rooted.
Try flashing stock firmware, ShinySide has a link in general to download samsung stock firmware.

I flashed the stock firmware. Wifi is somewhat working without rebooting. After a reboot i still get a message that factory mode is on and the phone turns off wifi. I also have to re-enter my wifi password to reconnect. Any ideas on how to turn off factory mode?
EDIT: Also when I trying flash anything in recovery I get a message in red saying unable to mount efs.
Try this Samsung Galaxy S4 : How to Get out of Factory Mode: http://youtu.be/d8dbrerUacw

I already tried that. But for some reason my efs folder is empty. I'm guessing I need those files.
EDIT: Anyway someone can share their EFS folder?
Even after flashing stock NH7?
Try reflashing again, maybe open nh7 rom on pc with adb and copy content to your folder and reboot.

I've flashed Shiny Sides modem through Odin. Then I followed it up by flashing his NH7 Stock ROM. No luck. The positive is that I have WiFi working again. The Bad side is that I get the "Factory Mode On" message on reboots and I have to re-enter my WiFi password.
What roms where you running before ShinySide's rom?
Where you on CM11?
Check your bootloader.

I was on Phoenix Rom 4.4.2. Then I flashed Eudemony 4.4.4. It had some bugs so I restored back to Phoenix Rom. This is when my wifi and factory mode on issues began.
Try flashing Phoenix again, see if that fixes it.

Panch, thank you for sticking around and trying to help me find a solution to my problem. I'll give re flashing Phoenix a shot later today and report back.

[Q] Connection Issue with Mobile Data - Modem Problem

I've run into a bit of a pickle with my root attempt on one of my LG G3s. The first went without a hitch while the 2nd didn't go so well. In order to flash CM12, I followed the LG G3 stock flash guide from hyleton to downgrade from Lollipop to 4.4.2. I then flashed CM12 with TWRP and hit a snag where the mobile data connection would try to establish, and the phone would black screen requiring me to pull the battery. The only way to get passed the CM12 setup would be to boot without the TMO SIM card.
Because I considered this a failed port, I flashed back to stock 4.4.2 but can't connect to the TMO mobile data network, but I am successfully able to get passed initial setup with the SIM Card in. IMEI and mobile number are still registered to the device, so at this point I'm assuming the issue is with a bad modem flash that occurred when I went back to stock 4.4.2. When I check the baseband version, the number/letter combo is quite large and doesn't seem to match with your typical Baseband versions, hence why I think I have a corrupt modem.
I can't find any modem software packages out there for the US TMO LG G3 variant, so was hoping someone could point me in the right direction or otherwise help provide some guidance on how to get my data connection back.
Hey,
I've got the exact same problem. Did you manage to repair it?
Thanks.
C.
You could try asking for a modem package for your variant here on the forums, otherwise you could try a custom ROM and wiping everything even the modem before flashing, most ROMs come with a modem built in.

Official 5.1.1 for T-Mobile (607t) issues

So I've having a bit of an issue with my 607t and I recall seeing some of the issues before. I was rooted before and on a custom 5.1.1 for a 605. Everything worked except it would sometimes boot back to recovery after power down. (known issue)
So today I went ahead and downloaded the official 5.1.1 and used Odin to flash back to stock. I'm not having any OS issues but am having a problem with wi-fi and the LTE radio. Wondering if anyone else has seen this and what was your fix?
1) The wi-fi will not remember passwords after a reboot.
2) After the update the unit is telling me that no SIM card is installed. Verified SIM is good on another device and tried a different SIM in the Note with same results.
Have flashed via ODIN again, factory reset a few times, remove/install SIM and the problems persist. I'm thinking there must be something from the 605 kernel that the ODIN flash isn't fixing.
Would appreciate any tips. - Thanks!!!!
You have to update the bootloader. There's a check-box in Odin for that.

That was the ONE thing I didn't do. And it worked.
That box was always greyed out when I loaded the file and didn't notice after the file processed that it was an available option.
Thanks!!!!

Have you performed a factory reset or full data wipe from recovery? (flashing an Odin package does not wipe data).
Wifi and bluetooth disconnecting can sometimes be resolved by deleting the wifi and bluetooth (or bluedroid) folders located in the /data/misc directory. A factory reset will also remove those directories and allow them to be re-generated after a reboot.
There is also KitKat firmware (4.4.2) available at sammobile.com that you could download and flash through Odin.
