Thank you, that's EXACTLY the type of thing I was wondering/looking. Much appreciated.

You mean your original qcn backup, I guess that's up to you but it shouldn't brick it. If your asking if it will brick your phone if you flash a modem, I wouldn't think so as long as your flashing compatible modem, but you would have to redo everything including restoring the qcn to enable the AWS band on new modem.

Before you do anything, make sure you made a nandroid including your modem and efs in Twrp (if you use it). Also having a backup of your own device qcn file which you should of made.

I don't know why you would want to flash another modem though, unless it's to upgrade current revision.
[AT&T Samsung Galaxy Note II] Poke_N_PDA:
ok, I followed this plan and I think I got it working.
[AT&T Samsung Galaxy Note II] riztaha:
So I bought a used note2 unlocked, but originally from Bell. after flashing the qcn, my Wind sim was working. But after a few hours it stopped working and went on roaming. I flashed it again and it started working, but a few minutes later it went back to not work again. After flashing or restarting, it would work and then not work on and off. I was running 4.1.2 so I downgraded to 4.1.1 as someone in another thread said it helped them. That did not help either. Has anyone else ran into this problem? There has got to be a solution!
[AT&T Samsung Galaxy Note II] Poke_N_PDA:
Is your phone unlocked? All this should do is open up the frequencies, not unlock the phone for use on other carriers.
[AT&T Samsung Galaxy Note II] riztaha:
Yes it is unlocked, unless if it is possible to lock the note 2 again because I did soft brick it and had to reinstall the firmware.

Also, the fact that it was not roaming proves that it was unlocked.
[AT&T Samsung Galaxy Note II] Darkshado:
Which likely means you reflashed the modem (especially if you used Odin), and need to reapply the mod.
[AT&T Samsung Galaxy Note II] riztaha:
Already tried that as well.

Is it possible to lock a phone again? Should I try unlocking it again?

Nevermind, it is still unlocked. Just tried 2 different sims from different carriers (that use the same frequency) and works with them. I'm probably just going to give the phone to my dad and let him use it. I'll probably buy a phone locked to my provider to make my life less difficult. I'm surprised there isn't a solution for this problem, I've seen only a handful of posts regarding the same problem I'm having.
[AT&T Samsung Galaxy Note II] REAVER117:
I'm having the same problem as you. I was hoping to figure out if it was a hardware or software issue but so far no one has been willing to send me a full NV dump so I could compare it with mine.
[AT&T Samsung Galaxy Note II] y2whisper:
Just using Tapatalk so a bit difficult to search but [MENTION=1078733]ReAVeR[/MENTION] were you the bell user that asked for the dump? Travelling for work today and tomorrow but if you are that person and still need it. When I'm at computer I'll go through and get that for u.
[AT&T Samsung Galaxy Note II] REAVER117:
Yeah, I was asking for an NV dump. That would be great, just use NV Reader/Writer and dump 0x0000 - 0xFFFF. You can delete the value at 550 if you want to remove your IMEI.

I'll message you my email, thanks!

LTE MAX

Just found out that Rogers in canada is offering LTE MAX it uses 2100mhz up and 2600mhz down on LTE bands. I noticed that the 7105 has 2600mhz lte bands any chance of getting that on the I317(M)?
[AT&T Samsung Galaxy Note II] Product F(RED):
Probably not. The i317 (AT&T) version and i317M are basically the same device. The i317 does 700 MHz (both up and down) and AWS (1700/2100 MHz). You can't use just one band out of two if one is upstream and one is downstream.
[AT&T Samsung Galaxy Note II] Poke_N_PDA:
Wow, at those frequencies, building penetration must be absolute crap. I know that 700 is a lot better than the AWS 1700 and 2100 we have on T-mobile. Sprint I think uses 2400 for their's here. I'll have to look up how their building penetration is.
[AT&T Samsung Galaxy Note II] jbplumbing.ca:
I was just wondering because the 7105 international model has 2600mhz enabled on it.

---------- Post added at 06:21 PM ---------- Previous post was at 06:17 PM ----------

Rogers also uses AWS but is now using 2100 and 2600mhz for extra fast speeds.
[AT&T Samsung Galaxy Note II] Product F(RED):
Yeah in my house I don't get LTE or anything above 1 or 2 bars on T-Mobile but on AT&T I get 5/5 bars. I live 2 blocks from a T-Mobile LTE tower.

[AT&T Samsung Galaxy Note II] y2whisper:
Just as a referesher, what NV values can I check to confirm that 42mbps has been enabled?
[AT&T Samsung Galaxy Note II] Product F(RED):
You don't need to check NV values. From the phone itself, bring up the debug menu (dialer -> *#197328640#) and press UMTS -> DEBUG SCREEN -> BASIC INFORMATION. Make sure some data is transferring in the background so the radio doesn't go to sleep. You should see this (the same thing happens on both my AT&T and T-Mobile Note 2):

I have band 2 right now but yup it matches. I had used that screen before but wondered if there was some other way. Thanks for the confirmation!
[AT&T Samsung Galaxy Note II] vinnyj85:
If its not as in your picture how do I do I get the 42 dc back
[AT&T Samsung Galaxy Note II] Product F(RED):
Just apply the mod. Nothing special required. The network also has to support it. So if you're on AT&T, no amount of effort will enable it. Neither will being in an area where T-Mobile has it turned off.

[AT&T Samsung Galaxy Note II] riztaha:
Yea bro, honestly I got tired of searching for an answer or a way. I legit tried so many different things and posted on different forums with no help. I ended up buying the t889. Love this damn phone, it's a beauty. I got a buyer coming for the i317m today too.

One thing I noticed was that on the i317m when it would work with Wind, it would only connect to 3G.

With the T889, I'm getting nothing but 4G :D
[AT&T Samsung Galaxy Note II] avantcs:
I dont see anything like that????? Here is a screen shot

Am I missing something?
[AT&T Samsung Galaxy Note II] y2whisper:
Yes you need to go through the steps. Start with pressing UTMS and go from there
[AT&T Samsung Galaxy Note II] Product F(RED):
Like I said, press "UMTS" and follow the menu path that I laid out. DC-HSPA+ varies by provider and by area (as in it might be on in some areas and not others).
[AT&T Samsung Galaxy Note II] avantcs:
thanks

Thank you. UTMS? I can follow from there.
[AT&T Samsung Galaxy Note II] Product F(RED):
UMTS -> Debug Screen -> Basic Information. (1 -> 1 -> 1). It's in my original post that you quoted.

Wind mobile

I recently got one and flashed the mod and installed the 'clean rom' and i have no problem at all.... I am not sure why you guys having these issue but i do suggest a few things to try.

1) APN setting?

2) try the service menus for changing the preferred radio band which i forgot what the code was ( I put it on prefer 1700 and it only lock to wind with no problem)

I am getting HSPA but the only issue i have is in area with really bad signal i keep having no network and its slow on locking it back on even in auto mode.
[AT&T Samsung Galaxy Note II] REAVER117:
We have tried all that. APN setting won't affect the network providers listed when searching. There seems to be some hardware or low level firmware differences between Note II's. I have manually set every NV item to mirror a working modded Note II with no results.
[AT&T Samsung Galaxy Note II] jayb222:
OK, so I'm using an at&t note 2 on tmobiles network. I enabled the aws. I had 4g but never got lte. I recently update the at&t radio to the latest and thought I had to redo the aws procedure. I didn't get around to it right away and low and behold I have 4glte all day on my phone! So I didn't do this and have lte on tmobile. Should I do it again? Is this even necessary on the new radio? I'm at around 30 mbs download on long Island. Can I get better?

[AT&T Samsung Galaxy Note II] GuyIncognito721:
So I'm about ready to pull the trigger but wanted some clarification due to conflicting reports in this thread.

I've read that if you are not in an LTE area, the phone will default to edge, even in refarmed 1900mhz areas. Can someone elaborate, confirm, or deny? Thanks. (BTW I'm referring to T-Mobile)
[AT&T Samsung Galaxy Note II] Product F(RED):
No.

1. If you were take the phone out of the box (assuming it was unlocked), and even if you never rooted it or attempted this mod, you would get T-Mobile LTE in areas where it's available. The phone's hardware natively supports 700/AWS (1700/2100) MHz for LTE. You can use http://ltemap.org/tmobile to check if you're in or near a T-Mobile LTE area. It's a non-official, crowd-sourced map.

2. In line with the above, if you do not apply this mod on the phone, you WOULD get HSPA+ (up to 21 Mbps, not 42 Mbps DC-HSPA+) in areas where 1900 MHz T-Mobile spectrum is available and running. These are referred to "refarmed" areas. You can use http://airportal.de to check if you are in or near one. It's a non-official, crowd-sourced map.

3. What applying this mod does is turn on the already-supported (software-disabled) AWS bands (1700/2100 MHz) for HSPA+ ("4G"), so that you don't need to be in a refarmed area to get normal T-Mobile data speeds. It additionally turns on DC-HSPA+, which won't do anything for your speeds on AT&T, but will allow you to reach up to 42 Mbps on T-Mobile.

This mod is completely undetectable and doesn't even require root or a custom ROM. You will need to reapply it, though, every time you flash a modem, whether it's a different one or the same one.

Aside from some minor unrelated hardware differences, the AT&T and T-Mobile Note 2 are the exact same phone. Here's why you need to apply the mod. Out of the box:

AT&T Note 2:

HSPA+ 850/900/1900/2100 MHz, LTE 700/850/1700/1900/2100 MHz - The 1700 MHz for HSPA+ is there but turned off by the modem.

T-Mobile Note 2:

HSPA+ 850/900/1700/1900/2100 MHz, LTE: 700/1700/2100 MHz

In the modem memory area, there are various "on-off" switches for different things. The T-Mobile Note 2 has AWS turned on, while the AT&T Note 2 has the same option, with the setting turned off. This area of memory is called NV Memory. The reason you have to reapply this mod every time is because the settings are defined by the modem, and flashing or reflashing a modem on an AT&T Note 2 will revert it to OFF. All this "mod" is, is restoring a backup of the T-Mobile Note 2 modem settings on an AT&T Note 2 to turn the option ON.
[AT&T Samsung Galaxy Note II] GuyIncognito721:
Thanks for the post. And you can flash any T-Mobile Note 2 ROM provided you keep an AT&T modem, correct?
[AT&T Samsung Galaxy Note II] Product F(RED):
Correct :) I have a T-Mobile Note 2 now, but when I had (well, still have but selling) my AT&T Note 2, I was able to run the official T-Mobile ROM. Most ROM installers ask you whether you want to keep your current modem or flash a different one, or they don't include one at all.

If you do accidentally flash a T-Mobile Note 2 modem on your AT&T Note 2, your IMEI disappears and your phone will bootloop with no service, until you flash back an AT&T modem (from personal experience). Don't panic, but I don't suggest you try it, because the partitions are different.
[AT&T Samsung Galaxy Note II] GuyIncognito721:
Why are you swapping out our ATT Note 2 for the TMob version?
[AT&T Samsung Galaxy Note II] Product F(RED):
I just don't like that the AT&T version lacks some modem settings (like GSM/HSPA+ ONLY mode) and the idea of restricting the device by disabling AWS. I know it sounds stupid. It's more of a personal ideology.
[AT&T Samsung Galaxy Note II] jbplumbing.ca:
Do you still need this? I just saw your post. I dont have wind mobile but I have used it in USA on t-mobile. I can see Wind as a service provider at my house in Cambridge though.
[AT&T Samsung Galaxy Note II] billb23ok:
Ok guys. You say you get tmobile lte on your out of the box att phone. I have a sgh-i317 and have not gotten any lte and I have tried everything I could find to enable.

I'm on 4.1.2. Skynote9 att rom. I read that in most cases ucama3 out preformed ucama4 radio so I went with the most popular. The file name you posted shoes that those are just rils in that zip.

[AT&T Samsung Galaxy Note II] yogi2010:
As far as I know it does work on all basebands, but you will you have to redo it anytime you flash one, even if you were to reflash the same one you're on. I did it on MC3 with no issues.
[AT&T Samsung Galaxy Note II] facinup:
I had the same problem as yours.

I flashed the qcn in 4.1.1, it only saw wind away; then I flashed it in 4.1.2, still wind away. In the end I put it into recovery mode, reset and reboot. It worked!! Wind home and 4G.

[AT&T Samsung Galaxy Note II] billb23ok:
Ok I have tried many modems from i317 and t889. I have tried nvitems from t889 (good one is to just restore the efs backup from a t889 using twrp. Works and imei stay the same. No need to connect and do aws mod it just works) I have tried changing setting in service mode (ended up doing a golden restore to change what ever I did back) I completely restored my phone back to ucamc3 stock. But in the end I am still getting and always got "unable to connect, try later" when phone connects to either LTE b4 or b17 any ideas on how I can get it to register. G, E, 3g, 4g on both 1700 and 1900 mhz are working fine

I have a sgh-i317 unlocked with free methode through network lock mode. I am completely rooted stock at the moment and am willing to try and test any method. I cant brick this apparently. Also I am using new apn fast.t-mobile.com and am only testing in t mobile lte covered areas. Oh and i went to t mobile store my sim is good and it gets lte in my sisters t mobile s4 and my brother inlaws t889
[AT&T Samsung Galaxy Note II] bigred1090:
I had the same issue with not being able to get the 4g lte even though my wife(at&t unlocked gs3 not rooted) and parents(original note at&t unlocked not rooted) both get it without any root or modem changes or enabling aws. I tried all firmware's and modems I could find hoping it would have an effect but no luck. I did the aws mod but still only got 4g .Then I did what jayb222 suggested and flashed the stock rooted Ucamc3 firmware and kernel and modem and ril files. Still no lte. so then I put my wife's sim in mine to make sure it wasn't my sim and put mine in her gs3 that I know gets lte. Then no 4g lte on either phone. Then I shut both off and swapped sim cards back to the original phones and powered on my note 2 and there it was!!! 4g lte symbol. I ran a speed test and got around 22 mbs down and 10 mbs up. I didn't mess with the apn at all and didn't force 1700 band on thru the hidden menu *#2263#. just left it on automatic. works great. Im in Fl by the way .If im understanding correctly no mod is needed to get 4g lte on the original at&t note, gs3 or note 2 because the 1700/2100 LTE band is already enabled.Hope this helps. Thanks to jayb222 for the advice:good: Here are some screenshots of everything.

im using the tmobile stock rom on my rooted n unlocked att note 2 and everything is fine boots up like tmo n everything for those who want the lte symbol to pop up like it did with att you need to flash the 15 toggle mod located in themes and everytime ur in a lte area you will know with out having to go to the main menu to see im in Dallas tmo just gave us here lte this month the highest I have seen is 32 dwn and 32 up
[AT&T Samsung Galaxy Note II] billb23ok:
Well I swapped my tmobile sims with a t889 and an s4 and found spotty lte on both devices so we activated another sim and tested it first on the s4 and the t889. Both got lte. My i317 on the other hand trys to connect but never does it goes back to 4g. I have never seen lte14 on this device. So like I mention I have tried everything I could think of or find online with no positive results. So I flashed jedi master 14 with saber kernel 29 and ucamc3 modem then rebooted put in rindis and then restore the t889 nvbackup. Rebooted. No lte but 4g ok I will just wait I guese until a hybrid modem comes out or I find a way to get a t889 modem to work with it.. Oh and still my imei is ok. I basically have a t889 with a i317 modem. Maybe off topic but would anyone know of a pit file for the t889 and if I could repartition my phone. That would help me alot.

Yes. What's weird is, for a while I had it set to "fast.tmobile.com" (like for the entirety of my month of T-Mobile service), and then randomly data stopped working one day. So I changed to epc.tmobile.com, and everything worked including LTE. I wasn't really comfortable with that solution though because I wanted LTE to stick (in case I move around and it goes away). So I just randomly inserted a dash in t-mobile (fast.t-mobile.com) and everything worked again.

Need original att i317 NV backup... please

Greetings,

I've tried this modification on my wife's N2, however, for the first few weeks of installing the mod the phone worked flawlessly; yet for almost a week the phone has been shutting down automatically. When this happens it takes a while to get it back up, and when it's on it will say it doesn't have a SIM card inserted. Did i mess the phone up? anyways. I want to know if it's possible to get a non touched NV backup for this device? I would like to restore it's factory settings and test out if the mod caused this problem or something else. Please... I was dumb enough by not backing up the settings my self :(

P.S.: Amazing work this is...:good:
