I live 2 blocks from the only reported LTE tower in Brooklyn and I can see it via a manual scan of networks, but I can't connect to it even if I force LTE only. It's not a huge deal though because my HSPA+ speeds are about the same as that LTE speed test.

I can even see MetroPCS's LTE network lol.

Just to clarify, you are located in Brooklyn NY right? Or do you travel through DC as well and get 3G/4G around this area? I'm still just trying to figure out if something funky is going on with my phone or this area or what. I think I'm going to try and go to a tmobile store and look at there phones to see if they get 3G/4G. According to the coverage map we should have it.

It will be interesting to see your results if this works. I'm pretty much at a give up point. I don't think installing custom roms with the same modem and AWS fix is going to solve my issue....if i have to go buy an att plan i'm gonna be pissed...:)
[AT&T Samsung Galaxy Note II] Product F(RED):
I live in Brooklyn, NY. My neighborhood where I live is a refarmed area (1900 MHz) but my college and job are both still AWS areas. It works fine in both areas but obviously better in a 1900 Mhz area since that's native to the modem. Not sure why the AWS fix isn't working for you. Maybe you're not applying it correctly with QPST? I'm on the latest AT&T modem (MA4 I think it's called).

So I flashed a T-Mobile stock, Odexed ROM via recovery (don't want to mess with ODIN because that can potentially repartition my device and brick it) and it booted up perfectly and everything. But I'm still running my AT&T modem. The nice thing about the ROM itself though is that it lets you toggle between LTE/3G/2G and 3G/2G only, which is great for saving battery when you're in a non-LTE area (95% of the country right now?). Not even the international N7105 ROM does that; that one has LTE/3G/2G, 3G Only, 2G Only. So I'll probably end up switching to a T-Mobile based ROM.

I'm going to attempt to flash a T-Mobile modem manually on top of this T-Mobile ROM, but I doubt it'll work. Can you link me to where you read someone successfully got a T-Mobile modem running on their AT&T Note 2? I'm curious to see how they did it, and if it can reproduced, I'd be willing to try it.

T-Zones and AT&T Galaxy Note 2?

Hi,

I saw someone ask about T-Zones and the Galaxy Note 2 from AT&T ... has anyone been able to confirm whether this will work or not? I'd like to keep my T-Zones plan and upgrade to the Note 2. I almost purchased a second hand T-Mobile version, but held off, because I've heard they get an "incompatible data plan" message.

If anyone knows, please post!

Thanks,

diznanl
[AT&T Samsung Galaxy Note II] Product F(RED):
I don't have T-Zones. However I noticed that when first signing up for T-Mobile's $30 plan on my home computer, at the end after it asked for my IMEI and I was in my newly made account, it incorrectly displayed my phone as an iPhone, but allowed me to change it to anything. I happened to choose Note 2, but I think I could have chosen a flip phone if I wanted. Like I said, it doesn't affect me because I'm not on the T-Zones plan, but hopefully that helps you. T-Mobile can't identify non T-Mobile devices because the IMEIs aren't in their database.

If you can flash the tmobile modem, I pray and hope that I can as well and that doing so will fix my issues. If the i317 truly is the same hardware as the t-mobile, then there HAS to be a way to make this work!!

Still have only edge.........

Not sure if this will help you or anyone but I had an adventure today at the ATT and Tmobile store. I found out that one, my i317 works perfectly well on att 4G LTE, had them test a sim card in there, was just curious.

I spoke to what appeared to be a relatively knowledgeable person at T-mobile who spent way too much time helping me considering they arent supposed to support non-tmobile phones. I'm just forwarding information, I don't actually know if any or all of what he said was true. The rest I just figured out by looking through the tmobile phone

a. The t-mobile rom, like you has the menu to switch between 4g/3g/2g to save battery life.

b. In the about device -> status, the network type is LTE:14 on the note 2

c. My area does have all the networks, 3G/4G/LTE which the Rep said were 2100/1900/1700 respectively. I saw the t-mobile note there

and it was super speed compared to my edge deal. He said you needed them all to access all the networks. In the service menu, I can

see 1700 and 1900 but have never seen 2100, however, the *#2263# menu on the tmobile phone was the same save one thing. They

had a "WCDMA/GSM mode only", "LTE/WCDMA mode only", and a "LTE/GSM mode only", though automatic was selected by default

d. The rep thought that changing all the APN settings to match what were on the tmobile note 2 would fix the issue, it didn’t but in case

you want them here they are. I only listed the ones with values or ones that I changed.

a. Name: T-Mobile US LTE

b. APN: fast.t-mobile.com

c. MMSC: http...mms.msg.eng.t-mobile.com/mms/wapenc (cannot post a link so instead of ...)

d. MCC: 310

e. MNC: 260

f. Authentication type: None

g. APN type (no spaces): default,mms,supl
[AT&T Samsung Galaxy Note II] Product F(RED):
I don't understand why this mod doesn't work for you because it works fine for me. The APN you mention is correct and is automatically set by the SIM (and it's built into the T-Mobile ROM as well). There's an older APN but that one doesn't grant you LTE access. I couldn't get the T-Mobile modem to work. I thought that flashing it and then trying to restore a QCN backup would fix it, but while QPST sees a device, it doesn't see it a "phone attached to it.

It probably also has to do with the bootloader and partitioning on the device (the partition sizes and locations for sure). I want to ODIN a T-Mobile stock ROM onto my phone instead of flashing it via recovery. But I don't want to permabrick my phone. I've seen people with an AT&T S3 find and flash T-Mobile S3 low-level files (platform files, bootloader, etc). But they were given it by someone a T-Mobile engineer who said that T-Mobile tested their files on an AT&T S3 originally.

Yeah, I have no clue either. I tried to get the dood to throw a different tmobile sim into my phone just to see if it made a difference but he said it wouldnt and wouldnt do it.

---------- Post added at 09:50 AM ---------- Previous post was at 09:32 AM ----------

Is there anything that you know of that could be preventing this. Could a bad sim card do it or ...something?
[AT&T Samsung Galaxy Note II] Product F(RED):
Well, a bad SIM could do it, but that's unlikely. Try cleaning the contacts with rubbing alcohol. And if you have a very, very old SIM (which I doubt), that would prevent you from getting access to HSPA+, but I doubt that's the case.

You could always say you just switched to a Galaxy Note 2 and now you need a MicroSIM (say you can from a Galaxy S2 or something). They'll replace your SIM for free.

I'm in the same boat as you, I've done the mod several times, including manually using QXDM but no luck. Is it possible that there are different hardware revs that don't support AWS?
[AT&T Samsung Galaxy Note II] Product F(RED):
Could be. Mine worked fine, but I still want the T-Mobile version because it does it natively. So I bought one on eBay just now with a messed up USB port for $395 and paid $20 for the replacement part. Easy 5-minute fix with no soldering. Just a simple flex cable part. I'll miss my wireless charging, but that's the only thing I'm losing.

I'm sad to hear that you are having the same problem but I appreciate you letting me know. I thought I was the only one and it was making me crazy.

Have you tried flashing a tmobile based ROM to see if it made a difference? I'm tempted to do that.

I'v tried, but it fails while flashing the modem. My guess is you have to repartition the phone which means that we'll need a PIT file. Right now I'm going through NV values, trying to figure out if I'm missing something that others have.

Flashing what modem? You're supposed to do it on an AT&T (or whatever your phone is) modem. This mod is modem-agnostic as long as you're attempting on a phone with the correct [for your device] modem.
[AT&T Samsung Galaxy Note II] REAVER117:
I've done the mod on the stock modem several times without success. I was trying to flash to T-Mobile to see if I would get different results.
[AT&T Samsung Galaxy Note II] Product F(RED):
That's weird... It could be that there were different revisions. Maybe originally they decided to just lock the band on the T-Mobile modem (since the T-Mobile Note 2 was the first out), but then they decided to make newer revisions based off the N7105 (cheaper?), which never had it to begin with.

I don't know if these values differ for different carriers, but if you go into the dialer and enter:

*#197328640#

Then go to 1-2-2-1 and then 1-2-2-6 and see what revisions you have. MDM is the Qualcomm modem (MDM9215).

Backup is successful.

EDGE only. Forcing 1700Mhz only gets zero networks found. I've tried the recommendations earlier to force different bands then go back to auto but that still doesn't work.

Odd things:

Before restore, GPRS was usally listed. After, it is now solid EDGE.

If I leave the usb cable attached and let the phone restart after the restore, I will see a 4G icon. I didn't mess with anything because it was still attached to computer. The second I pulled the cable out, I was dumped to EDGE. Maybe a coincidence.
[AT&T Samsung Galaxy Note II] Product F(RED):
I and most people unlocked via the menu trick on Android 4.1.1. Do a nandroid backup, then do the "note 2 free unlock" method, which requires a modem and ROM downgrade (it sticks forever though, so you can restore the nandroid after). That does something to the NV (modem memory) to turn off security. That may be it since most people used that method to unlock their Note 2, myself included.

Confirmation about TMo enable of AWS

I bought used i317 from someone who already enabled the 3G/4G with TMobile on it. This phone is unlocked and also it's flashed with latest 4.1.2 Tmobile rom. Maybe he used that free unlock thing. I am using TMo mvno and HSPA+ is working fine.

Notes: All HW info is identical to Product F(red) and from About phone it says SGH-T889 as a model number but Baseband is i317UCAMA4

So this method should work for sure. The original owner said that he used this method and then flashed the TMo rom which has no modem. HSPA+ work for ATT and Tmobile without any problems.

Now, I have one question. I have searched a little bit but cannot get the answer.

I don't care about LTE or WiFi calling. But I would love to have WiFi tethering and Tablet mode! Can I change my rom on this phone but without messing 3G/4G for tmoble or even worse bricking the phone. How can I be sure to flash the rom that will not touch the modem section?

Hope my info helps and thanks in advance
[AT&T Samsung Galaxy Note II] Product F(RED):
The "T889" identification is via the ROM can easily be changed. For example, my i317 is running an N7105 (international LTE Note 2) ROM and identifies itself as an N7105. To answer your question, you can flash anything as long as you don't flash or reflash a modem. If you do, you have to reapply the mod. But it only takes a minute to do, I promise:

Spoke too soon. There may be an issue with how the phone keeps trying to look for 2G instead of switching automatically to 3G/4G. Data wouldn't initialize so I restarted the phone in 4G area vs driving from EDGE to 4G area.

4G icon lights up with speeds on Tmobile/SimpleMobile of 3.7Mbps/1.7Mbps (D/U). Good enough.

*#0011#

Band 4 CPCH and FCPH (This is AWS right?)

2G -> 3G/4G lag??

3G/4G -> 2G perfectly
[AT&T Samsung Galaxy Note II] Product F(RED):
Band 4 on HSPA+ (3G/4G) is 1700/2100 MHz, correct.

It depends on what you set the phone to prefer; if you dial *#*#4636#*#*, you'll get a list of supported radio modes. Try WCDMA Preferred if you have that option. You can also force 3G/4G only if you choose WCDMA Only, but you'll have no 2G to fall back on, so you won't get calls in areas with no 3G/4G.

Also if you dial *#197328640# and go to 1-1-8-7-4, you can tell it to connect to 3G/4G first, and then 2G afterwards (UMTS_GSM).

I changed a menu setting that I think has to do with DC_HSPA+. Go into Service Mode (same dialer code as above), then go into 1-1-8-7-3-6 (DUALMODE IMPROVEMENT CONTR) and turn it on. It improved my data speeds noticeably. I'm not sure if it has to do with DC-HSPA+, but my speeds have been like this:

T-Mobile current caps, as far as I know, the $30 5GB data plan users at 15 Mbps on HSPA+, which is still hella fast:

https://www.dropbox.com/s/wqpoio0bkpxdqay/2013-05-12 19.27.39.png

And here you can see DC-HSPA+ is active:

https://www.dropbox.com/s/gh3au5eqpgdrd1s/2013-05-12 16.32.13.png

Even if I'm just oblivious and this mod already enables DC-HSPA+, turning DualMode Improvement on benefited my speeds.

[AT&T Samsung Galaxy Note II] Product F(RED):
No clue how to set it back, but reflashing the modem (and obviously the mod afterwards to reenable AWS) should do it. I think NOT ACCT is equivalent to OFF though. Samsung has a lot of typos in the modem menus, so it probably is supposed to be "NOT ACT" as in NOT ACTIVE.

I'm not sure what it does to be honest, but it didn't affect anything on my phone except improving the speeds.
[AT&T Samsung Galaxy Note II] inspron:
Got it. Not active sounds reasonable. Btw, the trade off is battery life, if any.

I reflashed AMC3 Modem but the ON/OFF stuck. Still can't get it back to prior state. I think this setting resides in the Rom, not the modem.

Based on the fact that DUALMODE IMPROVEMENT CONTR cannot be reverted back to stock, I highly recommend no one else try this unless you really know what you are doing.

Thanks for your help.
[AT&T Samsung Galaxy Note II] Product F(RED):
A QCN file is not a modem. It's just a set of parameters that the modem reads. Flashing any modem after applying the mod (even the same one you were on) will get rid of the mod because AT&T modems default the parameter that this mod flips on, back to off. That's why you apply the mod after you flash a modem. If T-Mobile modems were able to run on the AT&T model (they won't, due to different partition sizes), you wouldn't need the mod because the T-Mobile modems have that parameter (for AWS) set to on.

Flash any modem you want, then flash the mod. It doesn't matter what modem you're on when you flash the mod.

hi, I obtained an AT&T Note 2 that was simply unlocked by the dialer code method in these forums, I believe. I popped in my Tmobile sim, and to my surprise I got data immediately, on HSDPA9. I assume the reason is that tmobile has refarmed the network in my area to pick up hsdpa on the 1900 band?

my question is, would I get any further benefit from performing this mod?
