i started looking for text strings inside modem.bin file for both Verizon and Sprint, here is what i found so far:

Verizon has:

D:\workspace\HUDSON_USA_CDMA_MDN9x15_T0-VZW-MODEM\SRC\apps_proc\core\power\npa\remote\npa_remote_protocol.c

Sprint has:

D:\workspace\HUDSON_USA_CDMA_MDN9x15_T0-SPR-MODEM\SRC\apps_proc\core\power\npa\remote\npa_remote_protocol.c

So it looks like Sprint is using Qualcom 9215 chipset variant. it is curious that sprint's modem.bin is 88Mb where Verizon's is only 47Mb

Also we know now where the source code is :)))) it's on drive D: :)
[Sprint Samsung Galaxy Note II] leond:
LOL, I am application engineer working with similar kind of embedded software for embedded communication microprocessors. From my experience reverse engineering of compiled binary and making changes would be nearly impossible and definitely not practical for that kind of purpose. The only chance to get US carriers working is if someone leaks source code, or using a binary from similar device using the same exact chip.
[Sprint Samsung Galaxy Note II] nerys71:
pity :(
[Sprint Samsung Galaxy Note II] leond:
while going through modem.bin file I realized that it is a standard VFAT container that can be opened ,extracted and manipulated with MagicISO, I was able to extract , add and replace files from it. Now I can replace individual files from Sprint's modem.bin with files inside Verizon's modem.bin. BTW same files there are identical. See attached screenshot showing the differences between files inside modem.bin So far I tried replacing 2 files

Q6.MDT -it had some GSM related commands - no effect - I still could not see US GSM carriers also I do not have SIM card mode yet, so I am not sure if I should be able to see T-mobile and AT&T netforks in GSM mode when Sprint's SIM is "inserted"?

DSP2.MBN - this file has names of all GSM carriers in the world (whell most of them) - replacement of this file caused reset loop

I would not have time to further experiment with this probably till weekend. If someone wants to play with this I can upload both sprint's and verizons modem.bin files. You'd have to use MagicISO to extract Verizon's file, then open Sprint's file in MagicISO and drag verizon files in to it one at a time ,save,add modem.bin to one of the Sprint's modem zip files and FLASH it ,then test if it boots and US GSM networks become visible.

Dear folks,

Please confirm will it work with GSM carrier outside the USA? What tools do I need to enable GSM?
[Sprint Samsung Galaxy Note II] leond:
>Please confirm will it work with GSM carrier outside the USA?

The phone will work outside of USA, as is regardless of the MOD.

>What tools do I need to enable GSM?

No tools needed, just go to Settings->More Settings ->Mobile Networks->Network mode and select GSM/UMTS

Without the MOD you'd have to pay Sprint international roaming charges. The mod should allow insertion of local SIM card. the MOD has not been confirmed to work internationally yet.
[Sprint Samsung Galaxy Note II] nerys71:
thats what international's need. IE to be able to use a SIM card outside the US. ie buy a local card and insert. I am in the US so can't test it :)
[Sprint Samsung Galaxy Note II] Ashton_Durkhun:
Afraid I cant help on the coding front, but if anyone can get it working I'm more than willing to shell out $20-$30 to get USA SIMs working. Where I am there is no LTE yet and at lunch/dinner time my Speeds drop to ~300kbps on sprint (and only 800kbps the rest of the time), while my ATT (iPad) is still getting ~4mbps on HSPA+ 24/7 and I'd love to be able to pop in my ATT SIM from my iPad for tethering @ 3GB/$30 per month when I need it.

Also, on that note, if we get the radios fully unlocked couldn't the phone connect to VZW/ATT's LTE when the appropriate SIM is inserted since the note2 supports the mhz bands that VZW/ATT uses?
[Sprint Samsung Galaxy Note II] leond:
Unlikely, All 3 companies use different bands for LTE http://en.wikipedia.org/wiki/Samsung_Galaxy_Note_II

GSM had anly 4 bands (850 Mhz, 900 Mhz, 1.8 Ghz, and 1.9 Ghz) so a quad-band phone would cover all networks, LTE has I think somethig like 44 bands - i think it will be a while before we see a universal carrier independent LTE phone.

I live in Australia and ended up buying an galaxy note 2 ( sprint ) unfortunalty i did not know that version had no SIM slot

if I installed SIM-Card-Holder-Memory-Slot-Flex-Cable-For-Samsung-Galaxy-Note-2-N7100

http://www.ebay.com.au/itm/New-SIM-...n_0&hash=item3f20796136&_uhb=1#ht_2988wt_1125

would that work ( no need for sprints built in sim )

assuming all that would be left to do is firmware flashing >?
[Sprint Samsung Galaxy Note II] leond:
>would that work ( no need for sprints built in sim )

Hopefully. try and tell us please :)

>assuming all that would be left to do is firmware flashing

you shouldn't need to flash firmware, just put it in GSM/UMTS from "Settings" ,you should get voice right away. to get data you might need to update the apns-conf.xml file I've mentioned in post #200 of this thread

I would also buy

Samsung Galaxy Note II N7100 Middle Cover with Side Keys -White MBRPSS959

from http://www.parts4repair.com/ or any other place you can find it, this way you don't have to cut the existing one, unless you do not mind doing it.

I bought both the cover and the SIM holder from them, took about 3 weeks to get to US.

Also you would not get a 4G so it will be UMTS only if you even have that.
[Sprint Samsung Galaxy Note II] MasterCATZ:
I paid $500 for the phone ( should have been $450 but paypals exchange rate did not work .. )

I could have gotten n7100 new for $580 AUD the n7105 ( 4G version ) are about an extra $200 but I doubt our rural area will ever get it .. we only just got 3G ( phone is only used for NAV so speed no real issue ) plus i heard the 4G still drains the battery fast even when in 3G mode

main concern with these phones is that many seem to shatter the screen in weeks

currently around 200 phones on market with screens shattered

I'll order the kit its only $10 , i'll hack up the sprint case its usless to me any how :P

worst case senario I buy a new phone and use the sprint as backup screen then try and fix it later on as a wifi phone /ROM tester

even cheaper $5

Enabling GSM

I'm afraid it won't be that easy. Some people over on the AT&T Note 2's forum determined enabling AWS support for the AT&T i317 took modifying the NV partition. Perhaps something like this will have to be done to enable GSM support: http://xdaforums.com/showthread.php?t=2068041
[Sprint Samsung Galaxy Note II] leond:
this is different, Sprint Galaxy note 2 supports GSM out of the box according to it's specs

SPH-L900	Sprint Nextel

GSM: quad-band

CDMA/EVDO: 800, 850, 1900

UMTS: 1900

and sprint actually wants you to use GSM with this phone in other countries.

The NVRAM tricks discussed in the thread you mention however could be an interesting direction to look in to as far as enabling US GSM carriers

I found a good teardown video but it's not Sprint specific: http://www.youtube.com/watch?v=gD6zGVbqNMA
[Sprint Samsung Galaxy Note II] leond:
I've already closed the case so too late for the pictures, if I do it again, I can try to make some. It really comes down to opening the phone which is described in details in the first few minutes of http://www.youtube.com/watch?v=ArgxwyogunE, This is the most difficult part. then disconnect the connector from the SIM holder and carefully pop it up pulling it up evenly with a tiny screwdriver from all sides, it is sitting on a layer of a glue paper that can be reused later. plug in the new module and put the new cover back. took me about 20 minutes to do the entire thing.
[Sprint Samsung Galaxy Note II] wildta:
Understandable. Thanks for the response. Have you tried another SIM? Everything working as hoped?
[Sprint Samsung Galaxy Note II] leond:
Same as reported before - the phone can see the SIM card and the status is "Ready" as it shows in "Phone info" program which to me is an indication that the phone is not SIM locked. The phone does not see US GSM networks as it has nothing to do with SIM - they are locked somewhere in modem or NVRAM. I have no real interest in US GSM networks. I am planning to go to Europe in the end of the month and I am planning to test it then.
[Sprint Samsung Galaxy Note II] wildta:
Yeah I should have read through the entire thread before making my posts. I got a bit excited as I just got back from London and found a GN2 at my door as a gift from my brother.

[Sprint Samsung Galaxy Note II] leond:
You mean the microSIM form Sprint's iPhone? I don't think you can get it from sprint otherwise without explaining you've hacked in to the phone and that would make them extremely unhappy. I tried to request an MSL last week and got a hard NO from them, High ranking supervisor called me back and said that this is a world phone and as long as I am under agreement with them it would be a violation to put the phone on a different network even temporarily. it sounds like they are very serious about collecting international roaming fees. :)
[Sprint Samsung Galaxy Note II] DarkManX4lf:
That really sucks. So the Sprint rep said that the note 2 is a world phone? I thought a world phone would be one with a simple card slot like the touch pro 2 or photon.
[Sprint Samsung Galaxy Note II] m4xwellmurd3r:
I think it's still technically considered a world phone simply because it can connect and roam on both a CDMA and GSM network worldwide
[Sprint Samsung Galaxy Note II] nerys71:
that is hard core BS and flat out misinformation.

I swapped ESN's on all my renewals right their at the store zero issues. I also got my MSL's right their at the store.

you just got an anal retentive prick in the store is all.

I upgraded to Iphone 5's on two accounts and promptly swapped to the S3's I just got for trading those Iphone 5's and then promptly put the Sanyo 8400 back on the one account. zero issues.

put my Note II on sister's account promptly put her 3g phone back on and put the Note II on my account. (she was not using the upgrade because she does not want to increase her monthly price plan amount our account lets us switch back and forth at will)

as long as you stay in contract what he was was complete garbage. he lied to your face.
[Sprint Samsung Galaxy Note II] leond:
It is a world phone and it will work in Europe because Sprint has a roaming agreements with GSM carriers there. The only problem is that sprint does not want to consider it an unlocked world phone :)
[Sprint Samsung Galaxy Note II] rockerrock:
Would it be possible to desolder the "SIM" and resolder a clean ESN chip from another phone? Would it need to be a Note 2 sim chip?
[Sprint Samsung Galaxy Note II] leond:
I think the SIM has to be "married" to the phone by Sprint, and the SIM/chip in CDMA mode only affects LTE. CDMA and 3G are operating without the chip fine.
[Sprint Samsung Galaxy Note II] AlpineMan:
No need to desolder the built in SIM. The SIM and SD card module are both in a single daughter board and is attached to the main board via ribbon cable. I know cuz I already took my Note 2 apart to change from a white cracked enclosure to a gray one. ;) I have a theory that the Verizon, AT&T, and Tmobile daughter board version with SIM slot can be used on the Sprint Note II. Indeed, just this morning I saw an ebay ad that has this mod! Seller however claims that US GSM SIM cards such as from AT&T and Tmobile can't be used with the phone. Not sure if he's implying that overseas GSM SIM can be used and thus the phone can be used overseas as well.

This is consistent with the findings in the Verizon GS3 thread where someone figured out how to use GSM SIM cards with the VZW GS3. Can use overseas SIM cards, but not US SIM cards.

For those needing your MSL - call sprint tech support and advise them your needing to ##786# your phone (RTN) to reset it. They will give the lock code aka MSL. Per policy they are not allowed to just give the MSL upon request.
[Sprint Samsung Galaxy Note II] AlpineMan:
No need to call Sprint to get your MSL.

1) Download "Get My MSL" app from the Google Play Store.

2) Launch the phone app.

3) Dial ##3282#

There are several topics on a radio unlock for ATT S3 to use Tmobile networks. There are also numerous Verizon S3/Note2 modem firmware tools. I have a feeling that a adventurous developer could utilize this info to get US GSM working on a SPR Note2.

most of those do not have the same level of lock/protection. I've tried modems from different carriers and I've tried ROMs from different carriers. ROMS work fine with sprint modem , but still don't see US GSM carriers. flashing modem from a different carrier GN2 caused reset loop most of the times. You are not going to brick the phone if you flash a different modem as long as your custom recovery is still there, just reboot in to recovery and reflash the sprint modem. I have even tried to decompile modems in to individual files (modem.bin is a filesystem) and combine those from sprint and other carriers. I think it is actually pretty hard to really brick this phone if you know what you are doing.

$5 part arrived today ( FAST Shipping )

its larger then the sprint one and over hung on a few parts

for some reason the sdcard section is larger

I hacked up my old sim card and it looks like it picked up

my only problem now is i can not seem to find a way to setup the APN

I might try another ROM ( might have been removed option from sprint )

remember I have no intention of using SPRINT

downloaded this pdf file

www.thechinacellphone.com/micro_sim_template.pdf

3 cuts with scissors and a little sand paper for fine tuning

I am sure it would have worked but the card I am using needs an APN setting .. the other $1 a month card I have for emergencies does not need APN but not willing to cut it up :P

currently phone seems stuck installing CM ROM :S

good news it worked

(edit)

removing sprint sim board and putting in the cheapish sdcard / sim card holder using phone internationally

( got an bad sprint esn phone from USA to try here in AU)

phone is using GSM/UMTS

(end edit )

so I assume if anyone got an dual sim system they might even be able to keep sprint

what you do need how ever is

apn manager pro

titainum backup

the only thing I could not do was flash the device with anything other then sprint firmware

if I put h20 on directly I lost modem

so in the end this is what I flashed with

wiped

SPH-L900_L900VPALJ1_L900VPALJ1_L900SPTALJ1 / COMBINATION_L900VPLJ1_L900VPALJ1_CL265523_HWID04_HW-Rev0406_user_low_ship.tar.md5

then updated with

SPH_L900_LJ1_to_LJC.zip

rooted

then put on h20 leaving data alone ( if I wiped no modem )

adb installed apn manager pro

adb installed titanium backup

used titainium backup to make apn manager a system program

deleted all sprint apn's and adding in my apn

and got my data connection

tho my external sdcard / slot seems dodgy ( throw a gig on it and it drops out )

spent 30 hrs just trying to get another 7100 rom to install and got no where

looks like only Australian related firmware are for 7105

guess L900 is all I can use
