You can look current version at Settings - About device - Firmware Version (MC2 is latest, and i have a same problem with it)

You can downgrade just modem version instead of downgrading firmware - just flash SPH-L900_LJ1_Modem.zip (Google it) via CWM - and after reboot "Registering on Network" problem disappears - GSM turns on without reboot, in 3-5 seconds (but you still need to reboot system to swith back to CDMA)

P.S. Sorry for my English :)

I am in the US. I wonder whether the following would let me keep LTE.

I pull the battery out before boarding a flight for Germany, swap the sim-card board. Once I land in Germany, I insert a sim card from Germain T-Mobile and power on the phone.

Before returning to the US, I pull the battery and put the original LTE board back in place. I don't power on the phone until my plane lands in a US airport. Will this way guarantee that the Sprint network only sees the original LTE board or lets me use the original LTE sim card?
[Sprint Samsung Galaxy Note II] nerys71:
I don't understand. are people LOSING LTE access by plugging in a sim slot board? IE returning to the old board DOES NOT resume LTE ??
[Sprint Samsung Galaxy Note II] leond:
not sure where is this coming from. I played a lot with various GSM SIM cards here in US, and still get my LTE back the moment I put Sprint module back and switch to LTE+CDMA. If you want to be absolutely sure, make a nandroid backup before doing anything with your phone. This way you can restore it to exactly the same state it was before. Sprint doesn't care what SIM other than LTE you have in your phone.

Not sure what CWM is, is that an app from Google store?

thanks,

[Sprint Samsung Galaxy Note II] leond:
You need to FLASH custom recovery (CWM) do be able to FLASH radio firmware (modem).
[Sprint Samsung Galaxy Note II] ZenInsight:
Whoa whoa whoa. Pause. If you don't know what CWM or TWRP is then you might be in a little over your head.

1. Root the phone

2. Install CWM or TWRP to the boot sector (customer recovery menu) of the phone by following a youtube video or reading through the forums

3. ? (kidding...install correct modem firmware)

4. Profit

Has anyone tried to get a replacement GS4 or iPhone 5 LTE SIM as of yet programmed to their GNII?

And concrete info on the n7105 vs n7100 sim tray.

Thanks guys, keep it up. Getting my GNII next week and will be heading out of the country soon there after. Would love to get this up and working.
[Sprint Samsung Galaxy Note II] Alpha94:
Hi, I'm stuck at where I have no data. I can call and text but no data. Follow the instructions on inserting the apn of the network and the Mcc/mnc. Before I couldn't get no signal until I flash LJ1 modem using TWRP. Any suggestions?
[Sprint Samsung Galaxy Note II] leond:
For some reason I could never get Data working on Vodafone, but it worked fine on MTS and Beeline. For vodafone it was a SIM taken from blackberry, so perhaps it some how was locked to blackberry devices. Does data works with the same SIM and different phone?
[Sprint Samsung Galaxy Note II] AlpineMan:
BlackBerry is a different animal. I believe all data passes through either BlackBerry Enterprise Server (BES) or BlackBerry Internet Service (BIS) . Since your Note 2 isn't a Blackberry, you're not going to get data if you try using a SIM from a BlackBerry phone.

I tried two sims. One I had before and a new one. Also I tired my friends sim which gives me the same issues of no data. Could it also be android 4.1.2? Not sure just guessing.
[Sprint Samsung Galaxy Note II] AlpineMan:
Most likely, you have an APN issue. Download my Sprint/International APN xml file... Or manually add your own settings. You can't send MMS, too? If so, definitely an APN problem.

Sprint charges for their SIM cards. They charged me $15 for the nano SIM but it normally sells for $35. They said they won't charge if it is damaged though.

I was using a Vodafone SIM in London with no issues whatsoever with data or phone in my hacked SIM-slot enabled Sprint GN2. It was a brand new pay-as-you go SIM.

I also had no issues using a Lycamobile SIM in Copenhagen for voice. I had to call them to activate data on the SIM (because it's locked out by default) and then punch in the APN info.
[Sprint Samsung Galaxy Note II] eliasmanu:
The appropriate modem N7100 or others ?

Its still the GSM module of N7100 the right choice for GN2 L900 for oversees use ?
[Sprint Samsung Galaxy Note II] tropically:
same problem as rdouleh

I'm having the EXACT same situation as rdouleh outlined a couple pages back. The phone sees the available network, then when I try to connect says "registering on network" and then never is able to connect. I've tried all the previous modems, even flashed a complete rollback of entire firmware/kernel etc, nothing seems to be working. Any suggestions would be appreciated:confused:
[Sprint Samsung Galaxy Note II] daviderickson:
Has anyone used the latest modem internationally with success? Or do you still need the old one?
[Sprint Samsung Galaxy Note II] AlpineMan:
Thanks to eliasmanu... He tested all the modems. The ones that work are LJ1, LJC, and LK8.

[Sprint Samsung Galaxy Note II] daviderickson:
I just got my parts for this mod and took everything apart to install and noticed a few things that I thought I would check before completing the install. The new SIM board does not have a notch out of the bottom left corner like the L900 does, and as a result is sitting on top of an (unused) antenna port. Also near the top of the SIM board its notches do not align with the Sprint SIM board thus it is sitting on top of a metal notch. It also does not have the metal shield attached to the bottom of it, which presumably helps keep it in place. See my antenna and lifted images for examples. Does everyone else have the same issues? And did it cause any practical problems, or is it nothing to worry about?

I also ordered a Verizon backplate so I wouldn't need to cut out the notch in my existing backplate, I noticed the Sprint one seems to have some painted on gold metallic areas near the camera, but when I looked at the board there, the best I could tell was it was a ground. Any idea if this is going to be an issue with my replacement backplate not having it? I could always send it back and get another sprint one and cut a hole in it.

Also for anyone that cut the hole in their existing plate, have you had any kind of issues NOT having that metal shield in place when you use your original SIM board?

And lastly, is there any way to verify that this all works before leaving the country? I assume not since SIMs from other US carriers do not work?

Thanks!
[Sprint Samsung Galaxy Note II] wildta:
Make sure to download an APN app before you go and insert the APN of the SIM networks you are planning to use.

I noticed a lot of you bought the N7100 SIM / SD card combo daughter board. Has anyone bought the Verizon SCH-I605 daughter board instead? I'm thinking it may be a better fit with the main motherboard.

I can confirm my Sprint UICC/SIM off my Galaxy Note 3 works on my Note 2 with the SIM card mod.
[Sprint Samsung Galaxy Note II] nerys71:
really. the 4g sim card works in the note II ehh. I wonder can I use data on both phones if I put that sim card in another device? 3g on the note 3 and 4g on the other device? will that work?
[Sprint Samsung Galaxy Note II] AlpineMan:
Do you get 4G LTE on the Note 2 using the Note 3 SIM? Did you have to activate your Note 2 under your Sprint account in place of the Note 3 or is the Note 3 still active while you're using the Note 2 with the Note 3 SIM?
[Sprint Samsung Galaxy Note II] DarkManX4lf:
I would like to know as well.
[Sprint Samsung Galaxy Note II] bluesk1d:
Maybe I have misunderstood something in the process here so hopefully someone can point me in the right direction. I was under the impression that the carrier locks on these Sprint models only applied if you were in North America. I am in London and have my Sprint Note II with me. I swapped out the SD card reader/SIM slot per the guide linked above and all seemed to go well. I can still see the contents of the SD card. However, when I put in a known working SIM (3 Mobile), the phone just reports "Invalid SIM card" in the notification area. It doesn't prompt me for an unlock code or anything like that. Do I need an unlock code or something? Also, how would I enter it if the phone doesn't ask for one?

Thanks guys!
[Sprint Samsung Galaxy Note II] leond:
You need to flash older modem. The ones that work are LJ1, LJC, and LK8.
[Sprint Samsung Galaxy Note II] bluesk1d:
Bingo. Oddly enough I wasn't getting any data until I disabled APNs in the APN manager. Maybe the app wasn't needed afterall. *shrug*
[Sprint Samsung Galaxy Note II] jeffreyned:
So, just to clarify, does this mean that I can perform this mod and then switch the sim card from my Spring Galaxy S4 back and forth between the two phones? I love my S4, but I sometimes want a bigger screen. It depends on the day. I don't want to pay to have two phones, when I only want to use one of them at a time.

Could this work?

And, as my S4 has 4g LTE, would that be retained if I use the sim card module mentioned in another post that is for LTE?

Thanks!
[Sprint Samsung Galaxy Note II] gatolsf:
I did this mod, but the phone will only connect to data services not voice. Just so you guys know
[Sprint Samsung Galaxy Note II] leond:
when you insert SIM from a different phone in to note 2 , it there is a mismatch between the accounts note 2 ESN is under one account and SIM is under a different one, i bet sprint doesn't like that
[Sprint Samsung Galaxy Note II] jeffreyned:
That may be. I also have been wondering if it is possible to change the ESN. I've read various threads and it seems like people have done this for various reasons, but I can't tell how they did it, or if it was successful.

I have been researching different sim card holders and radio specs. It looks like the US Cellular Note 2 SCH-R950 has most of the same radio specs and bands as my Sprint GS4. So I would like to try this mod and see if I could then just switch out the GS4 sim to the phone I want to use that day. I'm not trying to cheat the phone company. I pay for the service, and that's fair. I just want the option to easily switch out phone models as I choose. I'm not trying to get both phones to have service at the same time.

So, if I have a Sprint Note 2 with stock rom on it, could I then just root the phone, install the APN file people have been talking about, and then flash the modem, and install the sim card holder from the SCH-R950?

Which modem version would I need to flash?

Is that all I would need to do?

I appreciate any help. I can't be the only one who wants to switch off phones once in awhile.
[Sprint Samsung Galaxy Note II] aranurea:
Lets say I want connect to T-mobile's network. I would do this mod and if all my APN settings are correct, when I plop in a T-mobile sim and swith to GSM mode and change the APN, it should work? Also would LTE work?

Also could I put on a N7100 back plate instead of cutting the sprint one?
[Sprint Samsung Galaxy Note II] leond:
You will not be able to connect to any GSM network in USA (T-mobile, AT&T, etc). And no, LTE will not work on any network other than Sprint.
[Sprint Samsung Galaxy Note II] aranurea:
Could you explain why it would not work? I understand the LTE not working. Just not that it wouldn't work on any other US carrier.
[Sprint Samsung Galaxy Note II] leond:
Sprint phones have radio/modem firmware written in a way to ignore any US GSM carrier. They will forcefully not detect or connect to such network. To overcome this you'd need a Domestic Sim Unlock For T-Mobile/AT&T or MVNO's wich exists for Sprint Note 3 and GS4

http://xdaforums.com/showthread.php?t=2593305

but will never exist for note 2 because it's outdated at this point and have no readily available SIM slot.

LTE wouldn't work because each carrier uses different LTE band and the Sprint Note 2 variant is HW limited to only bands particular to Sprint.

If you want domestic GSM you should go with a GSM Note. If you want to be both on Sprint and US GSM carrier (not at the same time) you should probably go with Note 3, also switching between Sprint and domestic gsm there is not a one button change and is a bit of a pain in the ass.

also even with note 3 it will be more difficult now because the unlock is for Android 4.3 and 4.4 is out.
[Sprint Samsung Galaxy Note II] NewTalk:
It's been done

I'm running a Sprint L900 Note 2 on T-Mobile right now. I have full talk and text but am still working out the bugs for the data which will only be HSPA+ when I get it.

Here are the pics to prove it.
[Sprint Samsung Galaxy Note II] ZenInsight:
So...the GS Note II will work on 3G for voice and Data out of the country with the SIM hack, but not in the country. but a GS Note III or GS4 will work IN the US as well with a SIM hack?
[Sprint Samsung Galaxy Note II] leond:
Previous poster claims he found a way to make GNII to work in US with T-mobile, also no instructions yet.

GN3 does not need a SIM hack, it has a valid SIM slot, to use it's GSM part you have to first ask Sprint to unlock it for international use, so the phone has to be active on Sprint. After that there is a way to make it work on US GSM carriers as well.
[Sprint Samsung Galaxy Note II] NewTalk:
GN2 dominated

As of right now I'm running my Sprint Galaxy Note 2 4.3 MK4 build with MA7 modem on T-Mobile with full talk, text and HSPA+. I live in Las Vegas

so it works in the U.S.
[Sprint Samsung Galaxy Note II] AlpineMan:
Interesting. How did you manage to get the Sprint Note 2 to work with Tmobile?
[Sprint Samsung Galaxy Note II] Tracyl1975:
works with MetroPCS GSM too

I also performed this modification. Downgrade to the MA7 radio. Follow SPH-l720 International Unlock. http://xdaforums.com/showthread.php?t=2415587

Follow SPH-l720 Domestic Unlock http://xdaforums.com/showthread.php?t=2530610

I replaced the Sprint ASIC with a SIM board from amazon for around 12$ SD card doesn't appear to work with this mod.

GSM provider needs to be selected at every boot for now. I get HSPDA speeds on MetroPCS (around 4-5mbps) MetroPCS needs to be given the IMEI of the note 2 before it will connect to Tmobile. otherwise registration will fail.
[Sprint Samsung Galaxy Note II] NewTalk:
I'm currently working on trying to get it to auto-connect to the tower, I'm in a reframed 1900Mhz area for HSPA+, I've gotten as much as 11Mbps.

Everytime I lose the tower I have to manually select the tower, it sucks until I can find the solution but it works better then having to buy a new phone
[Sprint Samsung Galaxy Note II] Tracyl1975:
I have been testing different modems this week.. mk4 reconnects successfully everytime, including boot

Stock 4.4 (rooted/sprint apps removed) mk4 radio, detroit area. Auto reconnect, no periodic loss of internet, no disconnects so far.

By the way, the sd card does work, however you have to push the sd card to the end of its travel and securely tape in place.
[Sprint Samsung Galaxy Note II] NewTalk:
I'll try the MK4 build and radio, I was on 4.3 but I downgraded all the way down to bootloader and build 4.1.1 because the battery is 300x better. I'll just find a 4.4 with the bootloader removed or I'll remove it myself. That's weird because my SD card works just fine, I used a GT-N7100 sd/sim slot
[Sprint Samsung Galaxy Note II] Tracyl1975:
If you are rooted with custom recovery, you can flash the radio only. I am running ne2, with mk4 radio. It seems its a revision problem with these sd boards. Some people are affected.
[Sprint Samsung Galaxy Note II] vbrookie:
Holy...

SO...

If I buy new Sprint Note II, SIM & SD Tray Slot Holder and back plate for N7100 and replace the sim holder and back plate. Will I have new international 3G/HSPA+ capable Note 2 for around $250?

I am going abroad once again for a year or two and apparently I can get 3G/HSPA+ on my Nexus 4. I can live with my Nexus 4 but camera is really crappy and I want larger screen.

Please someone confirm.

Thanks!

Back from the dead

I know this is an oldie but I just recently had to do this again as the wife shattered her Note 2 :eek:

I am 98% there but running into some issues related to it being a newer version of Android this time around.

I had my old Note 2 laying around so I swapped out the N7100 SIM holder from her broken phone, ran through all the software updates and rooting process. I am now at rooted 4.4.2.

I installed APN Manager and Titanium Backup Pro and went through those steps again. It would appear under the newer Android version there is an additional step of having to move the APN Manager apk to system\priv-app before it will actually let you create/change APNs.

At this point, I can create the APN and get it to connect *sometimes* it will also randomly disconnect from data services while voice/txt continue to function. Initially I thought maybe it had something to do with APN Manager having to be running or something like that but some of the later posts in here suggest that a different modem should be used. Originally the three that worked with this process were LJ1, LJC, and LK8 but now I am seeing mentions of MK4 being used without disconnect problems.

Is the MK4 modem now a 4th viable modem for the SPH-L900 with the N7100 SIM board? Just being cautious as I have no more spares laying around :p

Edit: So I flashed the MK4 modem and I just get the "Invalid SIM card" message in the notification area. Is there something else I need to do in order to get it to work with that modem version or is there an alternate suggestion?
[Sprint Samsung Galaxy Note II] taller238:
co-ask,

What's on earth the simpliest way to unlock the gsm (domesticly and internationally)?

I know the hardware Mod is the hardest part to mosy people. So:

Spcially, what parts (at least a sim-slot w/circuit) are needed and proven to work?

By what instruction to do the connection (like soldering ...) ?

Thanks.
[Sprint Samsung Galaxy Note II] chris.krisx:
hello everyone, firstly I must say thank you very much!!!! this thread has made my Sprint Note 2 now usable. :D :D :D I live in Guyana and after purchasing the phone, I then realized it had no sim slot. So off I went to modify it. I bought the N7100 sim module, replace it (wasn't too difficult to replace), then i rooted, flashed twrp, and flash the SPH-L900_LJ1_Modem.zip Modem and guess what?? calling and texting worked :D :D idk if the data works because I have access to wi-fi almost all the time. so that's all I need :D:D:D thank you once again :good: :good: :good: :good:
[Sprint Samsung Galaxy Note II] AlpineMan:
You should be able to get data to work... Just need to configure your APN settings. Have a look at my signature...the MMS fix thread. Use APN Backup and Restore app to import the international APN settings. There's about 1400+ entries in the xml file. More than likely your provider is included.
[Sprint Samsung Galaxy Note II] ShredderCamflap:
did you follow all of the instructions including flashing the tar to your Note 2? I was worried about doing that so I never actually flashed the modem they supply in the international unlock thread.

Good news on wireless charging my friends!

Hello all! I grew the testicles tonight to pry my beautiful titanium Note 2 apart, and the "pins" (if that's what you want to call the filed down nubs that sprint left us) DO WORK FOR THE WIRELESS CHARGING MOD! I repeat, they do work and put the phone into wireless charging mode. This is for the sprint version. Getting the back off is tricky, and you will have to drill holes in it to allow access to the connections, and possibly soldering some leads or pins on, but it does work.
[Sprint Samsung Galaxy Note II] Darkendvoid88:
Some simple soldering if required and an wireless charging compatible back casing and back plate should make it easy enough to add this functionality, I'm honestly that not interested in it due to how slow it charges the phone compared to a wall charger, personally I'm extremely interested in the sim addon so we can use other carriers internationally as well.

------------------------------------------

Also imho this was one of the easier to take apart phones, very similar to the s2 and s3. Nowhere near as complicated as the original epic though.
[Sprint Samsung Galaxy Note II] zack2491:
I wonder why Sprint didn't drill the holes and leave the pins. I (kinda not really) understand making their own backplate with a modified SIM cover thingy, but wireless charging would just mean more accessories for them to sell, which is apparently where the stores make the real money.

Hoping Samsung has some sort of black magic that allows full speed wireless charging, and not just a reproduction of Touchstone technology.
