Working Fine

Im currently on Sinergy Rom 4.1.2 and ussd codes works fine
[Sprint Samsung Galaxy Note II] zek13:
Works!

Thanks it really works! the only thing with this phone, I see it doesn´t have 3G for 850MHZ frequency, so it won´t work for those carreirs..

but I can verify it works great with EDGE in that network and works great with 1900MHz carrier 3G

(rom MA7, LK8 modem kernel, added the code in build file ashim Thanks!)
[Sprint Samsung Galaxy Note II] mephx:
Did you do anything special to get EDGE working?

I'm trying to do exactly what you have done, but I have the stock MC2 rom instead of MA7. LK8 Modem. I'm using Claro in Peru, and they have 3G on 850, but they have 1900 and 850 for 2G. Voice and Text work fine, but I can't get EDGE to work. I've put the APN info into APN manager pro, and used the build-in APN adding feature as well, but after saving nothing shows. I know it saved since I see it in APN manager PRO. Either way, I get no data.

I know the APN settings work, as it works fine in 2G/3G in my girlfriend's Nexus 5.
[Sprint Samsung Galaxy Note II] zitocontreras:
i really need help!!
[Sprint Samsung Galaxy Note II] mephx:
Ok, I thought I'd let everyone know the solution. I had to downgrade to MA7. Now everything works. I just made the previously mentioned changes to build.prop, so I didn't even need to use apn manager pro, although I'm sure it'd work too.

So it seems MC2 may be the problem for anyone who is unable to get gsm data, even edge, but does have phone and text working.

Has anyone tried MK4? I'd love to know if 4.3 is better or worse as far as world sim usage when travelling.

SCH-R950

Ok. My question.

I can use this method with another version of Galaxy Note 2?

For example, SCH-R950 (US.Celullar)?

Or I need to replace the entire motherboard to get GSM connection?

Because U.S. Cellular does not have this option enabled.
[Sprint Samsung Galaxy Note II] AlpineMan:
US Cellular version of the Note 2 doesn't have GSM. It is purely a CDMA phone unlike the Sprint and Verizon variants of the Note 2.
[Sprint Samsung Galaxy Note II] Declive:
Thanks.

But if I replace the motherboard with another, such as Tmobile, Sprint or Verizon should work right?

I am planning to buy a Tmobile motherboard with GSM support for $ 100
[Sprint Samsung Galaxy Note II] AlpineMan:
You can't simply replace the motherboard and put it in the old housing. For example, the housing that the Sprint and Verizon Note 2's use is the same, therefore you can transport a Sprint motherboard to a Verizon Note 2 housing and vice versa. The motherboard design for US Cellular is a little different... It won't fit in a Sprint / Verizon housing.

On the Note 3 however, the housing is shared between the Sprint, Verizon, and US Cellular variants.
[Sprint Samsung Galaxy Note II] Declive:
Ok, the housing it is no problem, I thought it was some other part would not be compatible.

Maybe this is the only possible solution to run a note 2 U.S. Cellular outside USA with GSM ...

If you have other comments are welcome.

Thanks for the reply.
[Sprint Samsung Galaxy Note II] AlpineMan:
I've done research in the past on US Cellular Note 2's. It's simply a CDMA only phone. It doesn't have GSM. Only the Sprint and Verizon variants have both CDMA and GSM.
[Sprint Samsung Galaxy Note II] juggamonkey:
So what's locking sprint note 2 out of being able to use att and tmobile in the usa
[Sprint Samsung Galaxy Note II] AlpineMan:
Domestic lock. I've seen domestic unlock method for Sprint S4 by simply navigating through special service menus. Not sure if it'll work or brick it. Look in the S4 thread if you're interested in trying it.

http://xdaforums.com/showthread.php?t=2530610
[Sprint Samsung Galaxy Note II] juggamonkey:
Man I love to try this ..I can't seem to find a cheap Verizon board anywhere as I was just gonna go with that method but if this is possible to domestic unlock it will be a great day for myself
[Sprint Samsung Galaxy Note II] AlpineMan:
Your best bet is to buy a Verizon board. Doesn't matter what custom ROM or modem/baseband you put in... It remains an unlocked phone and can be used on any GSM carrier in the world.
[Sprint Samsung Galaxy Note II] juggamonkey:
Any idea where I can buy the Verizon board
[Sprint Samsung Galaxy Note II] AlpineMan:
Ebay and craigslist.
[Sprint Samsung Galaxy Note II] blaq7145:
It really worked but new issues now.

THIS METHOD REALLY WORKED, I FLASHED CM11 AND REALLY ENJOYED IT... THEN ENTER 4.3 UPDATE: i flashed the 4.3 update and it still worked but right now i do not have mobile data isn;t working at all. I really want to get a feel of the feel of the 4.3 update so please any help. Thanks in advance.

Update:- I replaced with the international version N7100's SIM tray and GSM works on 4.3 Digiblur ROM with LG1 baseband but no mobile data. The tray of N7100 is a perfect fit but the SD card does not read now. It says "blank SD card". Will have to get a i605 tray and swap it once again.
[Sprint Samsung Galaxy Note II] AlpineMan:
The reason data isn't working is perhaps you have not configured/updated your APN settings according to your provider.
[Sprint Samsung Galaxy Note II] j3n660:
Succeed to modify stock 4.3 rooted ROM with Telkomsel (Indonesia) provider, after downgrade baseband from MK4 to LK8. But I can't get data to work. APN data already set. I installed "Offline SIM APN Database" and go to android APN Setting Page. I guess Data Bearer on APN setting should be set to GRPS/Packet Data. But there is no GPRS/Packet Data option, only "LTE", "eHRPD", and "Unspecified".

I flashed MA7 from LK8 because I unable to get GSM data. But it gives me "invalid SIM" error
[Sprint Samsung Galaxy Note II] dr.faramroze:
Confirmed SD card is blank or has unsupported filesystem. The new SIM-SD module of i605 was changed today but the same issue. It does not read SD card contents. GSM SIM works fine though with HSPA+ data. There is no USSD on L900 based ROMs, can flash an international ROM.

All the way in BW

Hi,i did like you said and manged to get it working on 4.3 after being anoyed with updates from 4.1.2,i must say though that the latter was better as USSD codes were working and all you have to do is flush the modem to LJ1. As For 4.3 Rom,Data works everything is great but no USSD codes,which i need to load Airtime and for Cellphone banking in my country.I tried looking for a USSD patch it seems to work only work for verizon.i am a noob but i have playing around with suggestion from this thread and tried all of them,the best for me would be 4.3,only if USSD would work.any suggestions?

Thanks

Everything Solved in 4.4.2

Hi guys, I just wanted to share my experience through this entire process.

I got an SPH-l900 and performed the GSM hardware modification.

After trying a lot of custom roms, all of the AOSP worked awesomely with mobile data, voice and messaging. TouchWiz custom roms did not, and I tried a lot of them. Regarding Stock roms, only MC2 stock firmware worked, and I somehow missed the TouchWiz interface when I used AOSP.

Today I decided to update to stock 4.4.2 using the file in the following link:

http://www.androidayos.com/2014/06/03/l900vpucne2-ota-update-4-4-2-kitkat-for-sprint-galaxy-note-2-l900/

After I updated the system, I rooted the phone using the following link:

http://www.androidayos.com/2014/06/06/root-l900vpucne2-4-4-2-kitkat-galaxy-note-2-l900-sprint-update/

Then I mkodified the build.prop file using Root Explorer apk as explained here:

http://xdaforums.com/showthread.php?t=1193245

I added the following lines at the end of the file:

ril.sales_code=LOL

ro.csc.sales_code=LOL

Then added the APN settings as in any regular android device and ... IT WORKED!!!!

Everything does and awesomely.

If you have any doubts about any steps in the process just ask.

Hope to have made your day better!!! (I am from Argentina and using Personal services)

Sprint GN2 Galaxy Note II GSM modification

Nice post. I did everything as mentioned by you. Thus using kitkat 4.4.2 NE2, rooted and edited the build.prop but still no luck (for build.prop editing I used build.prop editor, available in google play). I am outside US. The phone still doesn't detect any sim.

My question to you and those who like to help others is, how to downgrade firmware on Sprint Note 2 (SPH-L900) from KitKat to LJ1 or LJC or LK8 or MA7 or MC2.

Other thing which I noticed that perhaps there exists some update which, as soon as you get connected to the internet, installs and then prevents using this phone from being used as GSM phone (what we are trying to do here).

If GSM can be used on KitKat, it is well and good otherwise one will have to think of a way that even if you update your phone you should get the GSM working no matter what or stop the update process somehow.

Any ideas or thoughts are highly appreciated.
[Sprint Samsung Galaxy Note II] abatoir:
to downgrade you need to download mc2 modem from here:http://www.rwilco12.com/downloads.php?dir=Files/Devices/Samsung Galaxy Note II (SPH-L900)/Modems/TAR use oden to flash it to your phone in download mode! ask for the kitkat update i would advice not to go there till gsm can be activated on it! i had to install liquid smooth android os to get gsm working on my l900!

---------- Post added at 07:13 PM ---------- Previous post was at 07:02 PM ----------

the first time i did my note2 i used the sim module from the sch-i605! it works fine the only thing is i dont know about the 4g part! or service providers claim to have 4g speeds but the internet speeds say something else! so i only get edge at the top of my note2! (my lg g2 has never said 4g since i,ve been using it! the second time that i modded the l900 i used an l900 module and that works fine for me! still no 4g! i tried one from the sgh-t889! and that worked too,the only problem with that one is that its not the right shape!
[Sprint Samsung Galaxy Note II] clip3009:
With this phone sph-l900 it knly supports 3g bands. Sorry no actual 4g speeds. Says H or H+ but I ran speedtest on tmobile. The highest speed was about 1mb

[Sprint Samsung Galaxy Note II] blazie151:
Ok, so I rooted, followed the international unlock, followed the s4 domestic unlock (btw the bip blocking and ens settings are under sim not cda or umts), installed the sim adapter from a n7100 (I've done plenty of repairs in the past, I installed it without damage), etc. Now, I'm able to search for and see at&t domestic, but it won't connect when it tries to register. I'm on stock 4.4.2 w/ modem MA7. When I did this same procedure for an S4 l720 I ended up needing to put a custom rom on it first and did a mismatched at&t/sprint splice with a couple CM11 nightlies, and once it was flashed everything worked great. It was like the sprint rom was actually stopping it from getting connected to AT&T. Anyway, before I go down that rabbit hole again, does anyone have any suggestions for getting AT&T working on this heavily modified l900? P/S, I can see its on GSM850 w/ a signal strength of -79(to -85), but it still shows the old sprint number (now disconnected) and will not seem to allow the at&t sim to take over and use that network instead. Thanks for any advice received.

EDIT: I noticed that when you set bip blocking to 1 it reverts to 0. Think that might be an issue, but unsure. It'd be great to hear from someone successful in domestically unlocking this phone, or someone with more experience in this than me.
[Sprint Samsung Galaxy Note II] clip3009:
I got it to work on tmobile, back in December but I didn't like it because the speed was so slow on 3g/h+. It was like it would only get 3g speeds on tmobile. So I just got another phone. Tell you what, what I did was I copied alot of things from the sph-l720 build.prop and changed the build.prop in my sph-l900. Especially the model number. This was so I can use the s4unlocker.exe that autoprime built for us. After you do the steps in the gsm unlock thread for the sph-l720 you should be golden. It did take some time and tinkering but I did get it to work. Then again is it worth it? In my opinion, no but, nonetheless its fun :). I was so happy when I did because I thought I was the first in the world. After I wanted to create a thread on a how-to. But I couldn't find the solid method on how to do it again, then again my sim reader might have been damaged. So I just gave up and moved on to another phone. But good luck to you, hope my advice helps. Gsm isnt fun anymore without LTE :cool:
[Sprint Samsung Galaxy Note II] jocarog:
OK I followed the same process and after a couple days got it to work, I ran the mc2 restore with count reset using twrp, but did a backup of my 4.4.2 stock deodex using Philz, re-rooted my phone again and restored my nandroid and in the same session flashed MA7 modem, I had done the l720 domestic unlock previously but it was not working at all, followed the international unlock instructions, and after a couple reboots got it to register with T-Mobile but as mentioned before only getting 3g speeds even though it shows h+, here are some screen shots
[Sprint Samsung Galaxy Note II] blazie151:
I would be THRILLED with that result. HSPA+ on AT&T in my area should be better, but even if it isn't this phone is always on WiFi anyway. Could you link to the firmware you flashed through twrp? I'm still running the stock 4.4.2 w/ knoxx from an OTA update, and I think the build.prop is actually whats stopping it from working based on a previous comment. I remember when I did this on a l720 I couldn't get it working until I flashed a custom rom, but I couldn't find a good rom I was sure would work, so I mixed 2 CM11 nightlies and don't want to go through that again.

EDIT: Found the rom you were on and flashed it. Still no go for me. When I go to the phone and type in *#0011#, the first line says GSM850:Limited, what does it show on yours? On my l720 I'm running a custom kernel, but that doesn't seem to be required here. What am I missing?
[Sprint Samsung Galaxy Note II] jocarog:
Reminder this is for a Galaxy Note 2 SPH-L900

Flash MA7 modem, do the domestic unlock, then chose your network manually, register on the network, set your apn, get NE2 modem zip, reboot to recovery and flash it, reboot to system, profit!
