[AT&T Samsung Galaxy Note II] Product F(RED):
Yeah. Only T-Mobile/MetroPCS (they're both T-Mobile technically) in the US, and Wind/Videotron/Mobilicity in Canada. And if you're in an area where T-Mobile has LTE, you technically don't need it since you'll get that out of the box. If you're on AT&T, this won't help you at all.
[AT&T Samsung Galaxy Note II] mexigga:
Had LTE for a half hour after re-registering on the network (TMo) but now unable to receive LTE... Tried to re-register again in system settings to no avail.

Using MA4 radio...should I update it? Will that even help?
[AT&T Samsung Galaxy Note II] DorkyDev:
This hack is really rather useless now considering T-Mobile refarmed all their towers and metroPCS's towers. It was a good and useful hack before they did that, now I have my doubts about it...
[AT&T Samsung Galaxy Note II] mexigga:
Hack definitely doesn't help me but was willing to try.
[AT&T Samsung Galaxy Note II] DorkyDev:
Yea I did it to see if I get better coverage in low coverage areas, but haven't really been out field testing it.
[AT&T Samsung Galaxy Note II] mexigga:
Im going to update my radio..maybe that will help me...
[AT&T Samsung Galaxy Note II] Product F(RED):
There are some places where I would get EDGE if I didn't have AWS HSPA+ (there's no LTE in those spots either) but 99.999% of the time, I have LTE (and therefore refarmed 4G since they're usually one in the same areas). I have a T-Mobile Note 3 though so this doesn't even affect me.
[AT&T Samsung Galaxy Note II] mexigga:

Is your phone made in Korea or China? Which revision is ?
[AT&T Samsung Galaxy Note II] mexigga:
DN3 3.1.1

Korea. Rev.0.3
[AT&T Samsung Galaxy Note II] sharpeyedman:
I dont know if samsung or ATT is to be blamed for but newer batches like yours seem to have difficulties connecting to T-mobile lte. T-mobile is just clueless on this. I think its because ATT does not like seeing so many people taking their handsets to join Tmobile in recent years. Older manufactured Chinese built note 2s are known to connect on T-mobile lte better but that has not been yet been verified.
[AT&T Samsung Galaxy Note II] mexigga:
Update: I am getting bands 2 and 4... E, H & H+
[AT&T Samsung Galaxy Note II] ramachandren:
What did you do to get LTE bands 2 and 4? Any help would be much appreciated.

I too have korean made i317 rev 0.3 on SkyNoteAir with MK6 modem. I don't get LTE on T-mobile. (only get H+, H, E).
[AT&T Samsung Galaxy Note II] mexigga:
I'm not getting LTE at all... I enabled AWS as described on 1st post.

By keying in *#0011# I can see my N2 change from Band 2 to 4 (among others) but no LTE except for one brief moment.

I have the MK6 radio also. I am on Metro PCS (T Mobile) & am in an LTE area...
[AT&T Samsung Galaxy Note II] Product F(RED):
Your phone is switching back and forth between refarmed (1900 MHz) and AWS (1700/2100 MHz). I had the same thing happen to me when I had an AT&T Note 2 with the AWS mod: no LTE. I could do a manual network scan and see the network but the phone refused to connect. So I caved and got a T-Mobile Note 2.

You're lucky you're in an area with 15 MHz LTE. Mine has 10, as do most. It means more bandwidth and less congestion and therefore better speeds.

[AT&T Samsung Galaxy Note II] tritran18518:
You should get a new sim from tmobile. I had a old tmobile sim, it gave lte signal for my att HTC One X. But it couldnt give LTE for my att note 2. I thought some thing prevents my note 2 pick up tmobile LTE signal (i did this aws mod, switched baseband, rom, radio...). Yesterday, i decided to get a new tmobile sim, and now i have LTE.
[AT&T Samsung Galaxy Note II] DorkyDev:
There's also the *#*#4636#*#* code and then selecting device information... IDK If that'll do any good, did ya say your note 2 said it was made in korea or made in china, it says made in china rev 0.3... I'm lucky enough to have one of the 1st gen older one's from at&t, I guess that's why I don't have this problem.
[AT&T Samsung Galaxy Note II] mexigga:
Wow... Had no idea the sim could be the issue

Korea made... Rev0.3 also.
[AT&T Samsung Galaxy Note II] sharpeyedman:
Wow I need a new Sim card from Tmobile. Could you read the model number on the new Sim card so that we could try to get the same model?

I think it starts with TM.
[AT&T Samsung Galaxy Note II] mexigga:
I confirm its sim card related. Put a buddy's T-Mobile card in and LTE right away.

Last note I'm on Metro PCS (TMo) but that could also be sim related. Thanks for all the tips and help.
[AT&T Samsung Galaxy Note II] DorkyDev:
On a kinda semi related note, I think I remember someone telling me something about the average life of a sim card is 3 to 6 months and then on top of that they said if nothing is done with a sim card for 2 months it's deactivated and dead.

So I guess it's good to note to update your sim card every 3 to 6 months tops.
[AT&T Samsung Galaxy Note II] mindmajick:
Hm. Guess I should stop using the three year old sim in my skyrocket then. Lol

Please link where you got this information. It doesn't make any logical sense.

[AT&T Samsung Galaxy Note II] DorkyDev:
That's what

Was in reference to.

But I swear somewhere I gathered that it's a good idea to replace a sim card every 3 to 6 months. IDK If it was from general chit chatting or reading. LoL
[AT&T Samsung Galaxy Note II] DorkyDev:
Someone in this thread asked me for my APN's awhile ago, I never got around to trying to find a way to extract from my phone, but got them now and ready for import on 4.3 even, if you're on T-Mobile or metroPCS all of these APN's will work for you...

http://www.mediafire.com/download/co10rdd0pfdlibv/metroPCS-APNs.zip

Step 1. Download to phone and extract/unzip

Step 2. Install APNs Backup v1.0.5_1.0.5.apk

Step 3. Open ES File Explorer or another file browser that has root enhancement and shows hidden files and folders

Step 4. Copy .APNsBU folder

Step 5. Paste APNsBU folder in root of internal sdcard or you can try root of external sdcard

Step 6. Open app drawer and launch APNs Backup

Step 7. Restore APNs

Step 8. Grant APNs Backup Super User access when prompted

Step 9. Reboot

Step 10. Go to Settings > More Networks > Mobile Networks > Access Point Names and check to see if 4 APNs are listed 1. LTE T-Mobile, 2. T-Mobile US, 3 metroPCS and 4 metroPCS/T-Mobile if so enjoy!!

I noticed even before I switched to metroPCS and was still using T-Mobile Prepaid that I was getting the fastest speeds on the "3. metroPCS" APN even when I went over my data allowance and was throttled, faster by 2 to 5mbps above top speed.
[AT&T Samsung Galaxy Note II] DorkyDev:
^---Unrelated to this I think...

But suddenly I'm not receiving calls and it says every once in awhile not connected to internet and sim card error. But I do get data and sms.

Troubleshooting now, if all else fails trying a new modem then a new rom...
[AT&T Samsung Galaxy Note II] DorkyDev:
Apparently it was something with the rom that happened last night, dunno forgot what.
[AT&T Samsung Galaxy Note II] mexigga:
For convo sake...what rom ?
[AT&T Samsung Galaxy Note II] DorkyDev:
SkyNote Air G2 Note 3 Edition...

It happened last night I think after I was messing around with Service Mode or one of the 3 Phone Codes I have saved in my phone, I think either *#*#4636#*#* or *#2263# the one that lets ya select the LTE Bands to use and I couldn't get that menu to comeback up again for the rest of the life of that rom on my phone.
[AT&T Samsung Galaxy Note II] Product F(RED):
The menus are dictated by the modems. Newer modems don't include the menu on the S4 or Note 3. I THINK that's the case.
[AT&T Samsung Galaxy Note II] ramachandren:
I can also confirm that its sim related. I used my friend's sim and got LTE immediately.

So went to a t-mobile store, got my sim changed. The tmobile store guy refused to believe that its sim related until I showed him a screenshot of my phone with LTE. He finally agreed to change the sim, but unfortunately still no LTE with new sim. My new sim model number is TM9258.

Update: I tested my new sim with my friend's tmobile galaxy s4. No LTE on that as well. (got only HSPA+). So I now believe its something with my account.

Update2: I put my new sim on my friend's tmobile galaxy s4, which only got HSPA+ initially. I changed the APN to fast.t-mobile.com and after that, I got LTE with my new SIM on my friend's galaxy s4. Upon popping back the sim onto my att note2, I got LTE.

Update3: Lost LTE (back to HSPA+) after moving to a different cellular tower. So my guess is that my att note2 is having trouble registering itself as a LTE capable device with the cellular tower.

t999 modem for your i747

Much easier -- there is T999 modem that you can ODIN (flash) to your 747 one-step, really easy and it will say "Welcome to T-Mobile", then will work flawlessly. I got this modem/flash from this forum from ATT developers who needed to develop on 747, so it is a truly stable thing.

has someone tried it with new(er) i317 (Android 4.3)

Hi, has someone tried it with new(er) Note 2 from ATT? I have possibly the latest 4.3 and this did not seem to help at all? :(

It is network unlocked, I used QPST to "write/restore" the method #1 (post 1) attached QCN file (ATT I317 AWSMOD...qcn) ... all went well, but nothing changed - I am still seeing only E(dge) on Tmobile SIM, where with the same SIM, same location, I can get 4G on GS3 with TMOBILE modem....

Do you have an idea if the NV items changed for newer devices???

:(

---------- Post added at 08:09 AM ---------- Previous post was at 07:22 AM ----------

---- EDIT !!!! --------

:) :) :D ... after much initial disappointment, here is what helped me --

First, removed the TMOBILE SIM from the ATT Note 2

Second, used QPST to "restore/download" the mentioned in post #1 ATT QCN file (with NO SIM)

Third, placed my SIM in another phone (S3 with TMO modem) that works just fine on 4G/AWS

Rebooted the S3 (other phone), so that the SIM is "registered" on the TMO network

.... Then, removed the TMO SIM, and placed it into the ATT Note2, restarted... no change at first... but in a minute or two... it found 4G :)!....

SO how SIM is "registered" makes a difference... (I read similar issues with SIM cards, on S3 threads. People suggesting you use a "new SIM"... even making hilarious statements that a SIM card "degrades" after a few months, and you should go buy new one ... But, the truth is -- that it did make a difference here.

A similar story was that a husband flashes his phone with a new modem and did not seem to work, but then he puts his wife's SIM into it and it works(!), then even more peculiarly, put his SIM (that was in the phone during NV settings/flash) into his wife's phone, and that does "not want" to register to a 4G network....

WHATEVER IT IS - SIM SEEMS TO MAKE SENSE (OR HAS TO BE INITIALIZED SOMEHOW?)... OF COURSE THIS IS NO USE TO YOU IF YOU DO NOT HAVE ANOTHER TMOBILE PHONE... but I am guessing, the Note 2 is not your only phone if you are "playing" with it like this :)...

So good luck!

---------- Post added at 08:46 AM ---------- Previous post was at 08:09 AM ----------

Just curious -- why do you say that "either way" it would be (s)lower than a tmobile device?

EDIT #2

------------

Ok, the above mentioned "SIM related stuff", maybe not needed. I found out that I needed to use the UMTS service/band menu *#197328640# to set "PREFERRED BANDS" => WCDMA-All (UMTS -> DEBUG SCREEN -> PHONE CONTROL -> NETWORK CONTROL-BAND SELECTION...)

this now keeps my 4G on all the time, it is apparent now that I do not have LTE in my area, so I am not selecting this to be preferred.

But, in my area - no LTE (Tmobile LTE/reframed?)... so the hack is definitely useful (still)!

Abdul Haseeb

it IS possible to enable T-Mobile HSPA+ 42Mbps bands on your AT&T Galaxy Note 2, it’s running just fine on mine. You follow that five steps.

Step 1. You will need to put your AT&T Galaxy Note 2 SGH-i317 into a special modem mode so dial “*#7284#” on your phone.

Step 2. Choose “Qualcomm USB settings”.

Step 3. Choose “RNDIS + DM + MODEM” then connect a micro USB cable from your AT&T Note 2 to your computer.

Step 4. Make sure you have Samsung USB drivers installed, if you don’t download and install Samsung USB drivers first.

Step 5. Download and install QPST and start the QPST Configuration program.
[AT&T Samsung Galaxy Note II] Product F(RED):
Yeah, we know lol. The mod enables that already because the T-Mobile version has it enabled.

The IMEI and serial number look fine in the Phone Status, but I can't use QPST or Gaz's NV tools because of "wrong SPC". Can't getprop ril.MSL either - it's blank. Cripes, what now!?! :eek:

It worked

As a systems engineer I followed all the steps. I have a note 2 AT&T in Phoenix.

1. This didn't work for me when I was on the custom rom. It just didn't I don't know why but it didn't so I used the file I317UCUBMJ4_OneClick_BIN.exe which I found on xda a long time ago and kept for the oh crap I messed up. Its an all in one package that you don't need Odin because its included for the one click.

2. I restored back to the factory version which was Baseband I317UCUBMJ4 Android 4.3

3. I made my backup and made sure it was there after it said 100% because well I'm really OCD sometimes.

4. I started the restore and it worked the phone rebooted faster than I thought it would.

5. I rebooted twice and the new updates started to push down. One of them said dongle firmware installed (I'll have to remote that)

6. I've rebooted a second time ran a speed test and no change at all but I'll come back after I get my custom rom back on here.

7. The websites load a little faster but that is about it.

8. I'll report back later............

Hello Sir,

So you mean if I flash the latest KitKat stock ROM via ODIN, the modem will not be touched? And if the ROM for whatever reason has an update for the modem, it will prompt you?

I'm just concerned about all these people who says they have performed this mod and was fully working the first time, and when they update to a later version firmware and redid the mod, they are not able to receive signals or data connection is lost...etc...

Thanks.
[AT&T Samsung Galaxy Note II] mexigga:
I'm on MK6 and running 4.4.2 and the mod works. Most of the custom roms I've flashed do not touch the radio.

If you want a KitKat ROM that is stable check eZKAT 4.4

Hi mexigga,

So I can only flash custom ROMs and not offical ROMs from the carrier then? If I flash with the official ROMs from the carrier, that would include a modem flash? And may you confirm that you are flashing this via ODIN and not OTA...

I assume after flashing, the phone must be re-rooted again, correct?

Thanks.
[AT&T Samsung Galaxy Note II] mexigga:
If you flash Carrier ROMS OTA then you will get the modem. You can flash custom roms via recovery mode once they are downloaded onto our SD Card. I only used ODIN to root my device

I would check this thread out for more info
[AT&T Samsung Galaxy Note II] aftershocks:
I understand that OTA will flash modem, but what I'm saying is, if I can obtain the stock ROM file and store it in the SD card, would it still flash the modem?

Or are you saying that I must flash custom or else, any stock ROM even via recovery mode will still flash your modem firmware?
