I have done the hardware mod and have the phone working in South Korea (olleh kt) using The International unlock as posted. I am having a problem running the domestic unlock for the L720 on my Sprint N2. I have downgraded the modem to MA7 and followed the steps to get into the service mode but with the MA7 modem there is nothing to choose and using the "menu+>Key Input and typing 1 or 2" does nothing; i.e. I can't get into the UTMS or CDMA menu. Using any of the L series modems works fine and I get full service and H+ data that seems to go to about 3-4Mb/s. And as soon as I switch to and of the M series modems I get "invalid sim card" as a notification. Any help would be greatly appreciated. I'm running a stock rooted ROM Build L900VPUCNE2. Thanks! - Viperspike

You might need to use the drivers from Samsung and uninstall Kies if you have it on your system so the exe file can reboot and communicate with your phone properly... for the Las post upgrade to modem NE2 and you should be fine...
[Sprint Samsung Galaxy Note II] avercros:
I don't have kies installed, i have the drivers installed because i can flash the phone using odin, i'm goinf to do the complete process again today.

Thank you for your answer.
[Sprint Samsung Galaxy Note II] avercros:
Update.

I reflashed the NE2 rom by odin, performed the unlock using the L720 unlock guide, phone reboots when the windows program unlock it, performed the settings in the service menu and the phone doesn't detect the sim card.

Also, i have the MA7 modem.

Am i missing something?

Thank you.
[Sprint Samsung Galaxy Note II] jocarog:
In settings did you change your network manually? Have you added your apn? Man I'm out of ideas you having so many issues, I did not Odin NE2 I'm still on a MC2 bootloader without knox, I did the unlock using MA7 then after done with everything I flashed NE2 to gain stability on the 3g connection, Sim card should be detected once you do the L720 domestic unlock steps...
[Sprint Samsung Galaxy Note II] viperspike:
Do we need to be on the stock mc2 bootloader to do the domestic unlock? Using the NE2 bootloader and the MA7 modem there is no options in the service menu. I have the phone working with the SIM card using the L series modems, but only receive H+ data connection with an LTE sim. Any suggestions on how to do the domestic unlock?

I have 2 mint condition Note 2's so I ordered 2 verizon midplates and sim card slots from ebay months ago. When I got the parts I put one together right away and was never able to make at work. Both are running 4.1.2 which I think is my problem as I dont have the proper menu. I worked on this yesterday and kept running into invalid links and the finally found a stock 4.1.1 here http://xdaforums.com/showthread.php?t=1968136 The flash failed and then someone in the thread said that if I wanted to go backwards I would need to flash the LJC modem first to accommodate boot loader changes. I am gonna try that but I somehow hosed my custom recovery during the bad install of 4.1.1 Lucky for me I still have my old Samsung Jig from my S3 or I would have had a soft brick.

Anyway my adult kid is in need of a phone and I was hoping to get this phone to her today. Any help or guidance in the right direction ig greatly appreciated. I will be working on restoring my custom recovery while I wait for a reply.

Just tried to update to LJC full stock ROM via recovery and failed the partition check.

Edited to add: Okay never mind the first edit, got my boot problems solved by installing a different version of TWRP.

Forgot to mention the first time: In phone under about device it shows my serial number as 000000 I hope this isn't a deal breaker.

I do have a real purchased version of CDMA workshop if it can be of any use during this process.

Thanks

For those of us that cannot get H, H+ or even LTE after the Hardware Mod, there is still hope, but we need someone with a lot of talent and steel balls.

http://galaxynote2root.com/galaxy-n...3g4g-aws-bands-on-att-galaxy-note-2-sgh-i317/

That tutorial explains how to use QPST to write NV Settings from a different carrier, since all Qualcomm modems are the same and they are locked on a Software level.

Find Below a quote from another thread mentioning something similar being done in a note 2

If anyone has the chance to try this and can come up with a satisfying result, I think all the comunity will be deeply thankful.
[Sprint Samsung Galaxy Note II] Rich3077:
I would like to try this but sadly I lack experience and my balls are only made of soft brass. :p

Damn that's tempting to try, I may end up trying it if I cant get my issues resolved by tonight.
[Sprint Samsung Galaxy Note II] Luch170:
Working on it on my side, will come up with results ASAP

Results so far, only LJ1 Modem allowed the tools to recognize the phone. After following the entire tutorial, I rebooted the phone and it could not get signal at all.

After sweating and insulting vastly, I tried to access service mode but it would not allow me to change to GSM, it got stuck at WCDMA only.

I decided to flash MC2 modem and got my beloved signal again, now I can breathe properly and my heart rate is decreasing gradually.

Will keep you posted on my vital signs.
[Sprint Samsung Galaxy Note II] Rich3077:
It just so happens that I have 4.1.2 and LJ1 installed currently, it seems like fate is destined for me to try this.

Dammit.. I wanted to experiment something with CDMA workshop, I have purchased a full license and its giving me an error that my hardware has changed so I need a new license key. I emailed them, said they normally respond in 24 hours. I am not a happy camper, especially since I have made exactly zero hardware changes. In 24 hours I wont have the time to play like I do today, I am really starting to regret my purchase of that program.

Okay, so I just stumbled upon an app I didn't know about, forgive me if this is old news. There is an app called "Phone Info Samsung" that has several perso options. I clicked one and it did indeed have a menu to add a code, but from what I hear if you enter it wrong to many times it locks the phone. I tried once with 000000 App is here if you want to look https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo

Could you switch back to sprints Sim and have lte again?i know the phone would look wordweird but it's hidden by the battery cover.
[Sprint Samsung Galaxy Note II] viperspike:
As long as you put the Sprint "daughter" board back in it should work fine with sprint and LTE. The only thing this Hardware Mod does to you phone is give you the ability to use a micro-sim in place of the Sprint soldered on 4g LTE sim chip which is not removable from the sprint board.

Can u use a lte sim card holder. ..for n7105 or i317? It will work?

Im on kit kat...will work?
[Sprint Samsung Galaxy Note II] leo_hacker82:
can work any module. like i317m or n7105..works?
[Sprint Samsung Galaxy Note II] gnolasco:
!!

Hello I´m from Dominican Republic I made the modification but it say invalid sim, what I need to do now?
[Sprint Samsung Galaxy Note II] Back4More402:
I can say this works. The volume button and vibration motor plug must be relocated. Easy. The sprint frame must be used but be cut for sim. The tmobile frame wont close properly. I have done this.
[Sprint Samsung Galaxy Note II] BTslo:
N7100 works so others should too.
[Sprint Samsung Galaxy Note II] leo_hacker82:
Even if they are 4g lte? Cuz the n7100 its wcdma hsupa and the i317m or n7105 are lte. ..
[Sprint Samsung Galaxy Note II] leo_hacker82:
this will not work on 4.4.2?
[Sprint Samsung Galaxy Note II] pokey006:
Works fine on 4.4.2 NE2
[Sprint Samsung Galaxy Note II] jocarog:
It will work on 4.4.2 but you need to downgrade your modem to MA7 (jelly bean) and once done with everything go back to NE2 (kit kat), you don't have to Odin a 4.1.2 stock rom, just the modem to have access to the phone programming menu...

Still not supporting tmo/att (domestic gsm)?

Really confusing after this lot reading.

Simple question:

Has this mod supported GSM carrier in US (tmobile/att) now?

Any special instruction to enable that?

Thanks. :confused:
[Sprint Samsung Galaxy Note II] jocarog:
Yes it does work with att/T-Mobile... Read a couple posts before this, its pretty easy once you get the right firmware/software combination
[Sprint Samsung Galaxy Note II] taller238:
Oh, it's great to know.

But I still cannot locate the "right" posts after hard digging backwards.

Can you simply please post the link here pointing to that post, or give the number of page / post ?

Many thanks.
[Sprint Samsung Galaxy Note II] jocarog:
Replace the daughter board sdcard/simcard reader

1. Google l720 domestic and international unlock

2. Follow all the steps using a ma7 modem/software (jelly bean)

3. Input your apn, select network manually

4. Reboot to recovery and flash ne2 modem... Profit! Just Google all this steps and you should be able to find all the info you need, good luck!
[Sprint Samsung Galaxy Note II] taller238:
Glad to hear there's a solution.

Also, how could the resulted L900 switch between CDMA，Domestic GSM, and International GSM?

Just change software setting, or need flash back either Rom of them?

Thanks.
[Sprint Samsung Galaxy Note II] jocarog:
Flash any rom you want just make sure it is for l900, keep NE2 modem... it looks like you might need to do some reading about radios, there is a thread in the l900 forum that has all the radios for l900, like I said before use ma7 radio to do the unlock and NE2 to finish up the process, the radio is capable of handling GSM and CDMA frequencies... just Google l900 specs and look at the frequencies that it can handle... the domestic unlock does the "trick"... Good luck and keep reading...
[Sprint Samsung Galaxy Note II] taller238:
Is all the hassle only address the domestic gsm?

or I don't need do that if I use international gsm?

Thanks.
[Sprint Samsung Galaxy Note II] jocarog:
You do need to do the international unlock as well, both are needed... one of the steps is to enable international roaming, that's the only way you're going to be able to use the USA 3g/hsdpa frequencies otherwise it'll be blocked...
[Sprint Samsung Galaxy Note II] taller238:
I eventually found googled the thread for L720 Mod as this:

http://xdaforums.com/showthread.php?t=2530610

And found the corresponding MA7 ROM for L900 in here:

http://www.rwilco12.com/downloads.p...PH-L900)/Stock ROMs/MA7/Nodata Restore/Rooted

But when I tried to flash it using the ODIN, it failed with RED warning "SW REV. Invalid magic string."

I googled but no related clues.

Is the above place the right one where I shall get the MA7 ROM?

Please advice.

Thanks.
[Sprint Samsung Galaxy Note II] jlmancuso:
The way you are doing this it is trying to downgrade your bootloader which odin will not allow. Find whampasaurus ma7 and flash it. It will put you on ma7 software and flash the ma7 modem also.
[Sprint Samsung Galaxy Note II] pokey006:
He doesn't need to be downgrading the bootloader, just the modem
[Sprint Samsung Galaxy Note II] jlmancuso:
Maybe I miss worded it. I was not stating to downgrade the bootloader. The file he was flashing via odin contains the bootloader and that is why odin failed. To do everything you need for this mod you need ma7 rom and ma7 modem. The rom I suggested is ma7 based and flashes ma7 modem. So it would be a one flash deal and he can then follow the instructions from the OP.
[Sprint Samsung Galaxy Note II] taller238:
googled "whampasaurus ma7", no output at all.

When google "whampasaurus", find only one entry as this:

https://www.google.com/search?newwi....msedr...0...1c.1.62.serp..3.1.85.o8LOyKKsQyg

which is a ROM. I'm downloading the rom, and plan to flash it. Is it the one you suggest for MA7?

Thanks.
[Sprint Samsung Galaxy Note II] brk04:
It Works in Turkey

Thank you for the tutorial. I'll tell you guys what i did and i need to ask some questions.

I flashed 1.1.2 rom lj1 modem i did all the unlocks and then i flashed ne2 4.4.2rom and ne2 modem. Now everything is working but there is two problem for me. First problem is that gsm connection usually connects good but like in a 5 min it is down it is unstable, the other problem is there is only Edge no 3g? How can i correct these problems?
[Sprint Samsung Galaxy Note II] taller238:
What exactly should I do?

I assume it's by this order, I'm on 4.4.2 Stock now:

A. Root

- Odin flash twrp 2.3.1.1.tar, then twrp flash supersu.zip

B. Unlock (I can see my ICCID in status now, so not sure if it's been unlocked). Anyway, I'll use this app to unlock it again

- Please confirm if this app can do the unlock, b/z most IDs here are modding L900 from aftermarket, so no chance to call Sprint to unlock

C. Find the MA7 MODEM and Software (not ROM, but what's the software in post #246?) to flash - later on I'll post the link to confirm

D. Find the NE2 MODEM to flash - I'll get link to confirm too.

- Please confirm if the two modems here are the MA7 and NE2 to flash

http://www.rwilco12.com/downloads.php?dir=Files/Devices/Samsung Galaxy Note II (SPH-L900)/Modems/ZIP

Then everything be working? For both domestic AND international GSM?

I wish the question / answers can give modders the simplest way towards the goal.

Thanks.
[Sprint Samsung Galaxy Note II] taller238:
Let's get straight again. Digged a lot, still found Jocarog's post #155 is the one to follow.

Jocarog or anyone succeeding, please simply confirm if I'm guessing the right operation (resource) right besides each step.

I just wish to breakdown to make it clearly tangible to anyone just want to follow.

I've done the daughter board mod, TWRP, and root.

Any answer to the "HOW"s literally of real link/picture/operation would be welcomed.

Many thanks!
[Sprint Samsung Galaxy Note II] taller238:
Update: Almost done...

Sorry for the last two posts for my dumbness. Just searched a lot and strictly followed the L720 Mod,

Now can find TMO/ATT!

It's really amazing.

Managed to modify the file "apns-conf.xml". Seems working.

Now two questions arise:

A. Can I still flash a custom ROM? Will that override any of the GSM capability?

B. How to switch back to Sprint? Manually change all the entries back from the L720 thread, or just change the network options in the setting?

C. Is it possbile to use it on Verizon?

Thank you.
[Sprint Samsung Galaxy Note II] jocarog:
I stop responding to let you do your homework, glad you got it fixed, no offense... you can flash any custom rom but you would have to set your apn every single time or do your edit, to go back to sprint simply install the LTE card/SD card module daughter board that you removed and re-activate it, I don't know if you can go to verizon but there are guides to flash to boost and pageplus...
[Sprint Samsung Galaxy Note II] taller238:
Thank you for the response. I'm really sorry for posts of lacking homework :)

I'm now on the way of installing CM11, now that it won't affect the GSM modem function just achieved.

So far I failed two times on CWM 6.0.4.3 and TWRP 2.8.0.0, both have error "can't install this package on incompatible data".

I'm now on the Stock 4.4.2, and got the CM11 from here: https://download.cyanogenmod.org/?device=l900&type=snapshot

Please advice if anyone know. Since I googled but no immediate clue.

Also about the switching back to Sprint, has it to be so troublesome to replace the original non-sim daughter-board?

Because I remember at the moment of just completing the N7100 daughter-board replacing, I still can hear Sprint OTA and found its signal in the settings.

In other words, the GSM function is achieved only after I followed the steps in the L720 Mod thread - all "soft" changes in my understand, including the two modem flashes, and the service mode setting.

The N7100 daughter-board should also support Sprint network, right?
[Sprint Samsung Galaxy Note II] jocarog:
The reason it fails is twrp, get a cwm based recovery like Phil advanced recovery... I don't have this device anymore so I don't know if at this point the issues with twrp have been fixed, I don't follow that twrp thread anymore just jlmancuso threads, he has some aosp based roms that you might like... the n7100 daughter-board does not support sprint, the original board has the 4g LTE "sim card" for sprint embedded/soldered to it, it might work on the sprint's "3g", I don't know for sure...

SD cannot be found now

Just found the Sd card will eventually be 'lost'.

Not sure if it's accident or not.

But very repeatable.

Just cannot find SD card in the Stock ROM, nor in recovery.

Has to unscrew/detach the daugther board again to make the SD back. But then lost again.

Anyone has the same trouble? I was using the N7100 board, and tried several SD cards.

I605 daughter board has no mobile data

Just report back the trying of i605 daughter board of sim/sd.

the motivation is that the N7100 daughter board kept losing the SD （I tried many of N7100 boards）,

then tried the i-605, thought to be the same.

Now the SD part seems ok - no losing SD so far,

BUT there's no mobile data! (voice/texting is ok)

I thought the N7100 daughter board and the I605 one should have the same performance in the mobile data, but appears no so in reality.

Anyone can clarify why the N7100 can have mobile data, but I605 cannot?

Thanks.

All you have to do is follow the domestic unlock steps on the L720 S4 thread.

Sprint note 2 on Cricket/AT&T gsm network

Well I got my n7100 sim/sdcard board in today. The disassembly, install, reassembly went smoothly. I used a box cutter to modify my mid plate and it worked fine. I used whompasaros rom since it is ma7 based and includes the ma7 modem. Ran the international unlock program for the l720 then did the domestic unlock steps. Once all that was done I had no service. Spent hours double checking everything and changing crap. Flashed tw and aosp roms. Closest I got was having my cricket number show up in about phone but everything else was "unavailable/unknown".

I am pulling my hair out and getting annoyed by this point. So I start all over with the Whomp rom and get everything correct. Then I flashed the mk4 modem (didn't have ne2 on my sdcard). BINGO everything started working after that.

Long story short if it doesn't connect after doing the setup try a different modem.
[Sprint Samsung Galaxy Note II] jocarog:
I did use mk4 for all the unlocks, and to get 3g/4g I had to flash NE2 and that gave me a strong connection, I sold it like a GSM cell phone fully unocked, and the lady has not complained about it

Has anyone had issues performing the domestic sim unlock on the whomp rom? I have gone through all steps and can see ATT, TMobile and another carrier but the phone just hangs when registering. I have not been able to get a signal either. Ive tried all modems with the same results. I did notice that the phone does not display a uicc# when a sim is inserted and the sim unlocker app unlocks fine but says sim locked after restart. Any suggestions?
[Sprint Samsung Galaxy Note II] jlmancuso:
You did the international unlock first?
[Sprint Samsung Galaxy Note II] skandalous1:
I did. The only thing I can think of is that the phone is not internationally unlocked as I dont have a signal and the uicc# is not diplayed when inserting a sim card. I have ran the sim unlocker app with unlock confirmation but I get a simlocked status when I restart the app.

Personally I have never used APN PRO on any rom I use. I edit the rom zip replacing /system/etc/apns-conf.xml file with one from 5.x aosp rom (even on tw roms).

Hopefully this will help yall out.

Here is what worked for me after almost giving up.

Using this [ROM][4.4.4 TouchWiz][Note 4 Features] RainBow OS V6 in combination with LJ1 modem was the only way I could get this mod to work. Again its the only rom with working signal out of a few that I have installed.
