Running in to some issues and hoping someone might have had some luck...
I have an unlocked and rooted AT&T Note 2. Attempted to flash the T-Mobile (Stock) ROM/Modem/Kernel on the device using Clockwork. Cleared the cache and dalvik cache prior to and after flashing the ROM. After restarting the device (and prior to adding a Google account or ANYTHING) I am having the following issues:
1. T-Mobile SIM card is not being detected. When I go into settings to see the "status" the device is not displaying anything, when I go into mobile networks, it tells me to insert a SIM.
2. The device is randomly rebooting.
Any recommendations?
Never flash a modem for another device. Even though the 317 and 889 are basically the same there is enough voodoo involved that there can be problems if done wrong.
Try to search the at&t threads for this. I know they have covered it over there. They also have advice on setting up the 317 for use on Tmobile.

Hey Guys,
I have an AT&T Model SGH-1317 Note 2. For use on other networks, I unlocked the phone using the *#197328640# menu option. However, the phone failed to start the hot spot stating Mobile data was unavailable or Invalid Sim. However, I am able to tether perfectly using the same sim on an another S3 so I was sure its nothing to do with the sim or network operator settings.
I looked up and found XDA website with tons of information. I assumed my phone was locked by AT&T. Hence, I rooted the phone using CF-Auto-Root, backed up complete data using Titanium and using Rom Manager I installed the Crash Aroma 4.1.2 Rom. I wiped the data and cache 3 times as suggested. However, after the boot I am unable to connect to any mobile network. A Click on Mobile Network says "Insert Sim Card to Access Network Services". Dialling for IMEI number prompt a Null.
During Installation I noticed the Crash ROM has overwritten the Radio.. and I am assuming this is were the problem lies. but I leave it you experts.. Request Help!
Sunil.
What carrier are you using the device on?

Am currently on Du - A network in Dubai, UAE. I have been reading more forum information and some suggest that this may be related to the EFS folder getting corrupted which may cause the IMEI number to fail. Some suggest that there are software to rebuild this information by using the IMEI number behind the handset..
I also noted that my phone model has also changed to GT-7100 instead of SGH-1317, Wonder if the Crash ROM was apt?
Would you suggest installing a Jedi Rom specifically built for SGH-1317... or is the damage already done?
Back Online
Since I found no replies.. I had no choice but to give it to the Pros.. I handed my phone day to one of the Unlocking experts at a mobile store… He was confident that his technicians would resolve this. But after 2 Days, they have given up.. He suggested the phone would fetch me US$ 10 if someone used it as a demo unit at a mobile shop..
I was sure this was something to do with the Modem, IMEI and the all important NV folder. I was able to find a Stock ROM for the SGH-1317 and I also found a link at XDA about using EFS pro to change the IMEI.
Using Odin software, I flashed the phone with the stock rom. Unfortunately, there was one error when it tried to communicated on com1. Having no choice, I continued. Restarting got the AT&T style boot but it again froze on the Samsung screen. Dreading the communication error, I restarted several times with no results. Finally I realised if would be due to the cache and user data. I reset the phone to factor settings wiping out the user data and Whola.. The phone sprang back up..
Lessons learnt.. Backup your rom and data before playing with custom roms. Read Read Read and don’t flash in the middle of the night..
Since I am back online, I plan to stick to the stock and crappy 4.1.1 with all the AT&T dead weight. Will live without the ability to Tether until my fingers get warmer.. It won’t be long as I am already bit by the Custom Rom Devil..
Don't Give Up Easy..:good::victory:

Please I am having the very exact same issue and can't seem to have it fixed
Using CMW I also flashed it back to stock rom, didnt have any problem or errors doing it but im still getting No SIM Inserted. I have deleted cache and user data several times... Tried flashing CM10 and CrashRom see if they made a difference and still No Sim Inserted... tried 3 different kernels and still same issue
I have the exact same problem since yesterday. I've tried everything and anything to no avail. I'm very close to returning the phone.
I would really appreciate any input.
Same issue
I flashed crash rom 4.5, over the stock kernel and it gave me that same message. I've tried everything I could think of, which included everything in this thread to no avail... any further advice would be greatly appreciated.

Your username suggests that you have the N7100 device ??
If so. ..you are in the wrong place for support. ..As this is the SGH-I317 section.
If you are showing IMEI NULL with no baseband you may have to restore your backup image to correct the problem. .
If no backup image exists. ..you will need to flash a factory N7100 image from your section.
Look for the return to stock thread for your specific device and that should fix you up...
The CF AUTO ROOT files are device specific. ..so I hope you haven't damaged the partitions.
Good luck. ..g
Edit:
This will help. ..and will place you in the right section. ..
Just go to page 1...good

Hey there,
I'll try to be as specific as I can about this... So basically, I have the i747 through AT&T but am currently out of the country (in Japan) for a couple months and am using a prepaid data only SIM. Phone is unlocked and data works fine on stock, but I've tried flashing for the first time since leaving the US (with BeanStalk 4.3, MIUI, and LiquidSmooth using first CWM, then TWRP) so I'm guessing this isn't a particular ROM issue.
I'm unable to connect to the Japanese Docomo network when I flash. The phone recognizes the network, IMEI is still intact, but the APN is gone (so I tried APN backup/restore to get the option back, but still no data). Then I reflashed most of the i747u modems, also to no avail.
Also got out my AT&T SIM, which still works on stock. APN shows up, but no voice/data.
Anyone have an idea of what the problem could be? Any other options I missed? As a disclaimer, I don't really have experience beyond clearly written directions posted here, but I read a lot before I try anything and have been flashing my last couple phones with good success.
Thanks so so much to anyone who reads
I'm running CM-10.1.3 (stable) on my phone (T999) with the UVMD5 modem and last night I lost all signal for about 30mins. I rebooted a few times and toggled air plane mode on and off without any success. Eventually, I got signal again but no data. I can send and receive calls and SMS but I have no data connection (can't browse, no email notifications, etc.). I have tried all the options under the Network Mode settings without any success. Occasionally, I'll see the "E" sign for Edge/2G but there is no data available even then. I also tried updating the modem to UEMJ4 and UEMJC but observed no changes. WiFi works just fine. Could this be a hardware issue? Is the antenna somehow damaged? Is there anything else I could try?
Try another Kernel. If that does not help, Odin flash to Stock. If that too doesn't work then suspect tower issue.
Hardware is a possibility. But lets not get ahead of ourselves
Thanks, I'll give that a shot and report what I find. I doubt that it's tower related since I'm having the same issue at home and at work and my roommate, who has an original Galaxy and is also on Tmobile, is not having any problems.
I flashed stock JB 4.1.2 (UVDMD5) using Odin since I had it laying around and I'm still seeing the same issue. What else can I try?

Check your APNs. Those are under Settings > Advanced > Network. Its called Access Point Names. It should be set to epc.t-mobile.com. See this thread for details.
Try UVDLJC or the prior version to MD5. If that too does not help then take to T-mo for antenna Repair.
Check your IMEI number. If it is zeroed out PM me. Otherwise just let us know here, (but don't actually post it).

The IMEI is 0. I never backed up the EFS folder but I was able to get the number from tmobile.
I have been having the same issue since June 2013 after doing to 4.1.2 OTA update from T-Mobile, at the time I didn't realize the IMEI was listed as unknown. So for months I have not gotten a cellular data connection better than Edge. Also after that update trying to check for a software update on the phone resulted in an error, and Kies told me my firmware was not supported for upgrade. Looking in some support forums and talking to T-Mobile got me nowhere, so I have just been dealing with it.
Wanting to upgrade I recently used Odin to load the official T-Mobile 4.3 ROM on the phone, actually hoping that would fix my issue (still in the dark about IMEI) which it did not.
I had never backed up the EFS folder, since as a standard user I had no idea what it was and while performing an update from my provider I didn't realize anything would need to be backed up outside of Kies. Now that my warranty is expired and having to take matters into my own hands I am on a quest to find a fix, however I don't want to "brick" my phone in the process, at this point I know enough to be dangerous.
Currently;
Android 4.3 Official T-Mobile ROM
BASEBAND is good T999UVUEMJC
Kernel 3.0.31-1962493
IMEI is Unknown
Looking at some other posts here at xda-developers I tried to follow some instructions on repairing or restoring IMEI using NV reader/writer, however I cannot get NV reader/writer to connect to my phone.
I have noticed in 4.3 when using *#7284# in the dialer the QualComm settings are no longer present, only MODEM and PDA are available.
I have poked around in Service Mode *#197328640# and found a setting that I thought might help, but I have a feeling it is the same thing as 8#7284#
[1] UTMS > [6] COMMON > [4] DIAG CONFIG > [1] USB or [2] UART
So at this point I don't know how to proceed, again I am not thrilled about loading a custom ROM, or really any ROM for fear of making the issue worse or bricking the phone. I have read a lot of posts about no longer being able to make calls due to IMEI issues. Everything works right now except cellular Data.
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:

Updated to 4.4.2 today via ota. Was originally a Verizon 8.3 lte, switched to t-mobile. Was able to toss a sim card in and update apn ran fine. But after ota update today it no longer reads tmobile sim card. Have updated apns, continuing to get notifications that tablet activation incomplete, your tablet will try again when you restart. Have restarted plenty of times, on boot get welcome to Verizon red startup screen. Then goes to straight to screen unlock. Anyone with a idea of how to fix this. Tablet is rooted.

same here... I skipped the initial setup steps. Device shows no network connection to t-mobile. When I go to Settings-> About Tablet-> Network, com.android.phone crashes
To go back to 4.2.2:
Root, Flash aboot.img and TWRP.img
http://forum.xda-developers.com/showpost.php?p=54533937&postcount=2
Then reflash 4.2.2 TWRP backup (dunno if you can do direct flash without factory reset... try?)

needs root
Code:
adb shell
su
#backup current modem

#restore modem from 4.2.2
dd if=/sdcard/modem.img of=/dev/block/platform/msm_sdcc.1/by-name/modem
doesnt work for me even if i flash the modem. do you get the activation notification when you reboot your device paper?
Doesn't work
Same. Anyone have a fix?
I fixed mine. I had to reactivate it with a Verizon sim card. Go through the whole process. then i was able to pop in a tmobile and add the APN settings for Tmobile.

Did you use an active Verizon sim ?
We are getting a new Verizon G pad. Do we need to insert a Verizon sim, upgrade to kitkat and then insert T-mobile sim?
Thanks for your help

Mine was already on 4.4.2. I just inserted an active Verizon sim card, went through the setup process, then swap out the sim cards.
i run this line of code and i get operation not permitted , im not sure what im doing wrong. ive tried it over a few diffrent computers, and have also ran adb of the tablet it self thru term... any ideas?
dd if=/sdcard/modem.img of=/dev/block/platform/msm_sdcc.1/by-name/modem
also its rooted with TWRP and CM12.1 installed but i have no cell service the options in settings are grayed out i cant enter and settings manually. and the Network app wont work to change anything
want to set it up to runn off AT&T the best i can
Did you give terminal Superuser permissions with "su"?
yes super user was granted
I don't know what's wrong then.
You could take my ROM zip from my signature, delete all the partition IMG files out of it, put the modem.img you want in, and edit the updater-script to remove anything having to do with flashing the other partitions, then flash the resulting zip in TWRP. Make sure you know how to recover and have everything saved that you want to keep from internal storage in case you do something wrong, though.

You know, I haven't been able to get mobile data working on any CM-based ROM on the VK810 yet, so that's probably your trouble. If you want mobile data you'll have to go stock. Some people had some luck on CM-based ROMs but then eventually it stopped working. I didn't have any luck at all.
Thank you for the info, I think I'll just wait for a possible workaround, until then I'll just use internet share from my phone.... That and I haven't the foggiest idea hownto do what you told me to do with the updater and what not lol , so rather than really screw things up, I'll just stick with WiFi..
