I now went back to a stock version of android 4.3 with root but this actual Rom I really like and the phone is showing up as T-Mobile and calling out/receiving calls and text work fine but still no data at all... heres what the download of the Rom now shows up as d2att_I747UCUEMJ2_root4.3_noknox.tar.MD5
anyone?? I think if I could get in to edit my apn I would be fine but the phones saying insert Sim card to access mobile networks when I goto more networks but like I said the phones working fine jus no data
I think I fixed my data issue by flashing a new modem thatnks to this thread http://forum.xda-developers.com/showthread.php?t=1831898

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
Hey guys,
I am trying to get my Galaxy S3 working on the Freedompop network with BYOD.
I flashed to stock firmware:
MD4_update_FULL_Odex.zip
because the MSL code (##786#) that I was supposed to use to reconfigure the radio to Freedompop's network, did not work in CyanogenMod.
In the stock firmware, the code worked, and I got cellular data and voice. However, when I flashed back to CM, the Sprint icon is orange, and I don't have data connectivity any more.
This is the version of CM I flashed to:
cm-11-20140708-SNAPSHOT-M8-d2lte.zip
Any ideas for what could be wrong?

Same with Carbon, but in carbon if the preferred network is 3G, or 1x, it will connect to those networks but it will not connect to LTE. I also noticed that in carbon it connects to LTE and 1xRTT instead of LTE and 1x800. Also does anyone know any possible way to go to 4.1.2 stock (from stock 4.4.2 KK)? I am also on FreedomPop btw.
Found A Fix
I searched a bit and found a fix, that didn't work at first but worked if you use it a specific way. It's the APN causing the issue. This was found out by user Merudo here on XDA. The fix is to do this:
1. Download a Ting APN fix .zip
2. Go on the ROM with working LTE (stock) and take it's apns-conf.xml (it's in /system/etc/) and copy it to the computer
3. Replace the apns-conf.xml in the Ting APN fix
4. Copy to phone with ROM and Gapps
5. Flash it in right after you flash your rom and gapps (e.g. 1st flash your rom then gapps then the APN fix)
6. Reboot and setup and it should work.
Again Kudos to Merudo for figuring this out.
Anyone get note 3 working on here? I'm on boost now with on 3g.. wondering if I can flash just a uicc card to freedom pop lte??
Im using a D855 LG G3 running the bumped v20F stock firmware (see the android dev thread) with no issues except this one...
Im currently in singapore using a SIM card that supports 4G on a network that has good 4G coverage (M1) but i simply cannot get LTE/4G to work at all.
Ive tried the WCDMA/LTE/GSM/Auto in mobile settings and it always without fail sticks on "H". Via the hidden menu i select "LTE Only" and i get no data connection icon (or data) at all.
Searching the mobile networks ive tried manually selecting the M1 advertising as LTE on the list but the same thing - it defaults to "H" and wont shift off there.
The APN im using is the one advertised by M1 for 3G and 4G coverage.
I dont think this is a ROM problem hence posting it here but ive got no idea how to solve it. Anyone got any ideas what else i can do/change or check ?
Other than rooted, the stock ROM is not modified or customised in any way - it was a factory reset, clean install.
Similar issue in Argentina, with 20b on my D855. Tried using the 3845#855# code, selecting even the LTE only thing, but nothing, no LTE. SIM card and service is working right (tested on a Nexus 5).
Any thoughts would be appreciated.

Try reinstalling LTEConfigs.apk under system/app
Unfortunately, I can't root or flash anything on this phone until I know it can use our LTE bands, or should I return it. Any other way?
I downloaded and installed NOBLE Note 7 ROM for a 910F. It installed and booted. Everything worked except the WIFI and Cellular. I Odin the radio from our phone but that didn't help. One of the VZW data fixes got me wifi. It's great rom and very stable.
Is there anyway to get the cellular working on a ROM that was made for a different 910???
Kinda surprised the data fix didnt work, you might have to go into the Mobile Networks settings and change the mode, or maybe even change the access point names.
