Unlock question guys

Can this be done for page plus and if not which providers? Does the chipsets in the mobo support only GSM bands, HSPA, etc, and no page plus iccid (sim card)?
[Sprint Samsung Galaxy Note 3] iBowToAndroid:
Page Plus is CDMA. That would be flashing, not unlocking
[Sprint Samsung Galaxy Note 3] Omega 1:
auuu auuuuuuu!

Page plus have sim cards with "4g" now. The sims are in the room next to me.
[Sprint Samsung Galaxy Note 3] Mrhunter13:
it's still CDMA not gsm the page plus is nothing more than Verizon prepaid ...
[Sprint Samsung Galaxy Note 3] Omega 1:
lol

For some reason I knew that you would pop right up to asnswer that question. I knew that but how do yoy get tge sim to initiate in a Verizon phone? Good imei.
[Sprint Samsung Galaxy Note 3] Mrhunter13:
lol its late and I'm bored ....for Verizon phones it has to be a clean imei and if the phone is flashed to 3g it has to be unflashed with dfs or CDMA work shop changing NV only to ruim only to get the sim card to work in the phone with 4g
[Sprint Samsung Galaxy Note 3] Omega 1:
4g

why can't we get 4G on the Sprint note 3. does that have to do with locked nv items or is it the bandwidth spectrum on the chipset
[Sprint Samsung Galaxy Note 3] Mrhunter13:
are u talking about using the page plus sim card
[Sprint Samsung Galaxy Note 3] Omega 1:
4g

Yes. Im gonna look up the chipset.
[Sprint Samsung Galaxy Note 3] Mrhunter13:
it's because Verizon and sprint phones have different frequencies with their sim cards
[Sprint Samsung Galaxy Note 3] vipersinu2:
Verizon network

Verizon network uses band 4 or 13, neither of those bands are available on the n900p so data will not work with an mvno verizon sim
[Sprint Samsung Galaxy Note 3] nicoagtuca:
i'm not really sure what's going on

i'm not sure wat it is but it'll show bars, and E, but when i try to make a call it says no network available. anyone have this problem?
[Sprint Samsung Galaxy Note 3] vipersinu2:
e

i am assuming your on a t-mobile sim, use gt tools, testing/phone info. switch to LTE/GSM/CDMA auto (prl)

Success WITHOUT getting an unlock code from Sprint!

Ran the universal Sprint unlocker (it's here in another thread), proceeded with the steps listed here.

Also, after flashing MI3, knox stayed at 0x0. Good news for whoever still has warranty on it (this phone was activated in November 2013, so no warranty there :P). However I had no service on T-Mobile until completing the steps. May work for other carriers, based on what I've read on gsm hosting. Good luck to all. It's definitely possible.

PS: Trying to get the APN settings to be able to be changed by editing the build.prop rendered the device unbootable. Going to flash a custom ROM now.
[Sprint Samsung Galaxy Note 3] rbeavers:
That might be the Edge network old fall back gms signal. Did you set the apns for your carrier yet?

That might get you to the 3g network.
[Sprint Samsung Galaxy Note 3] es0tericcha0s:
I found it easier to just use the APN shortcut through the Galaxy Tools app.
[Sprint Samsung Galaxy Note 3] nicoagtuca:
edit

Okay... so I can sometimes receive text messages but i cant send any out and also the signal is really inconsistent. Always no signal (x) and will receive signal every now and then

I've attached a photo showing that it does have bars but I can't do anything at all

Which thread
[Sprint Samsung Galaxy Note 3] idone:
That's bad info/misinformation, uicc unlocked devices WILL give "invalid sim" notification for US GSM sim... and will do so up until you set GCF setting in ServiceMode Menu and reboot.
[Sprint Samsung Galaxy Note 3] es0tericcha0s:
Depends on the update it's on as well. I was getting the Invalid SIM message even after doing all steps on NAB with MI3 modem. Only after I updated the modem to MJ4 did the message go away and I was able to connect it to GSM. This has happened on the last 2 I have unlocked for domestic use. All the other Samsung devices I have unlocked for domestic use, the Invalid SIM message went away after just using the SSU app and nothing else. This includes both versions of the S4 (many) and the Mega (just one so far).
[Sprint Samsung Galaxy Note 3] dwegiel:
All right, so my device works on GSM/UMTS/HSPA fine. How do I use the LTE network as well? Anyone have a proper solution? Thanks!
[Sprint Samsung Galaxy Note 3] rbeavers:
No LTE, phone doesn't have the freq. bands needed for att or tmoble.

There was talk about the chip set having them, but needed to enabled.
[Sprint Samsung Galaxy Note 3] shadowcliffs:
I'm experiencing weak signal, poor voice quality and issues on listening to voice mail with T-mobile. I come from a T-mobile Note 2 and I start to feel sorry to use this unlocked Note 3 on T-mobile.
[Sprint Samsung Galaxy Note 3] iBowToAndroid:
Yes, that's what I was referring to - the S4 specifically. Something must be different in the Note 3

For voicemail, use their Visual Voicemail app from the Play Store. For everything else, not much that can be done - that's the price of using a Sprint phone
[Sprint Samsung Galaxy Note 3] es0tericcha0s:
Which modem are you using on which update? These sound like the symptoms of a modem mismatch, but also yea, it's not going to work as well as an official T-Mobile phone. Just how it is. It's missing the 1700/2100 hybrid HSPA band T-Mobile uses as well as LTE so things are going to be different.
[Sprint Samsung Galaxy Note 3] shadowcliffs:
I'm currently on MJ4.
[Sprint Samsung Galaxy Note 3] es0tericcha0s:
I was under the impression that just the unlock needed to be done on the older modem version but once done, that it will survive through modem upgrades. Have you thought of trying a KK modem to see if it will help? You can always downgrade back if it doesn't work. Unfortunately I have not had a chance to test this theory myself so can't promise it will work, but only takes a few minutes to flash modems so not really a big loss if it doesn't help.
[Sprint Samsung Galaxy Note 3] shadowcliffs:
I flash the latest NK7 rom together with the stock modem and the unlock is not kept. It says to keep the unlock one can't go higher than MJ4. Welcome other to report back.
[Sprint Samsung Galaxy Note 3] es0tericcha0s:
Ah ok. Well that sucks...The S4 you can upgrade the modem to KK and everything still works fine. Did you try and run the Sprint Samsung Unlocker app afterwards and reboot?
[Sprint Samsung Galaxy Note 3] laofan:
You are under wrong impression. Read the op. It is stated that if you flash a new modem, you would lose the unlock.

Read the op. I have flashed lots of roms and from my experience and op's instructions, as long as you keep the unlocked modem (MI3 or MJ4), your phone would keep unlocked.

Once you flash a new modem( even from mi3 to mj4), you would lose unlocked. The only way to get unlocked back is flash mi3 or mj4 and do the unlock process again.
[Sprint Samsung Galaxy Note 3] es0tericcha0s:
Maybe you should re-read the OP. It says nothing of the sort in regards to changing the modem would cause you to need to redo the process.

In my experience, upgrading from MI3 to MJ4 actually made the unlock start working. See my post #912. So I think it's just the upgrading to KK modems that would prevent the unlock from working.
[Sprint Samsung Galaxy Note 3] laofan:
this is OP: http://xdaforums.com/showpost.php?p=49017708&postcount=3 change to whatever modem other than your current one would void the unlock and make your phone go back to sprint( flash mj4 over mi3 would also void the unlock and you need to do the unlock on mj4 )

It is stated very clearly on Post#2 as well, you need to be on modem mi3 or mj4 to do the unlocked. Once you are unlocked, you are pretty much free to flash any rom as long as you do not switch modem.

Both MI3 and MJ4 could make the unlock working, not just MJ4. My device has been unlocked on both modem and is working fine on both modem.

whoever else reads the post, please read the first page several times. As long as you follow every step, you would get your phone unlocked just fine on MI3 or MJ4 modem.

other modems would not work, like OP said and everyone else is telling you. If you still don't listen and keep trying other modems, well, good for you.......
[Sprint Samsung Galaxy Note 3] es0tericcha0s:
I've no clue where you got this, " change to whatever modem other than your current one would void the unlock and make your phone go back to sprint( flash mj4 over mi3 would also void the unlock and you need to do the unlock on mj4 )" as it is nowhere in the 1st 3 posts and definitely not in the 3rd post as you linked to. Also, like I stated, flashing MJ4 over MI3 did not undo the unlock. Quite the opposite, as it is the only thing that made the unlock START working when that was the only thing that was changed after I did the steps on MI3 and received no service of any kind on 2 different phones. Both I had started with installing NAB via Odin. so it's cool that both worked for you, but there's obviously something else at play here, and you didn't mention which update you were on when it was working with MI3 for you. I had previously gotten it to work on MJ4 with the MI3 modem before the Samsung Unlocker app came out and just had the phone unlocked through Sprint. The last 3 I have unlocked were already updated to KK with 2 of them needing to downgrade to NAB as they had the bootloop issue that some Note 3s experience with newer than NAB firmware and the MI3 modem.

I am in no way a n00b about this stuff as I have unlocked several Sprint phones including many S4s (both versions), the Mega, and Note 3, as well as the LG G2, G3 and Flex and HTC One M7/M8/Max and Moto X (1st gen). My mistake was thinking this would be similiar to the S4, which does allow you to update the modem back to KK after the unlock with no issues, which is obviously not the case with this phone. Maybe at one time this might have mentioned it in the OP, but is clearly not there now as I have re-read those posts multiple times as well as the entire thread as I have done with all of the phones I unlock so I am as familiar was possible with different issues, scenarios, and methods.
[Sprint Samsung Galaxy Note 3] laofan:
let me ask you, what is the firmware version for the last 2 s4 before you unlocked? Do you remember? I highly doubt that.

I basically unlocked as much as devices as you do( except the mega). There is no way one could remember all the details on all devices. Not to mention that I flash rom/modem/odin every now and them. But what I always do is follow exactly OP said. "EXACTLY"

If Mi3 is a no go for you, that is fine. maybe your device is different, but do not ignore the fact that MI3 is still working for other users. Simply deny the fact that mi3 could unlock is misleading for other users.

Last and least, your device is already unlocked on MJ4. what is point of complaining mi3 or other modems or your fail on unlock? Go flash roms or enjoy the phone in other network.

You might keep quoting me. but sorry, I have a life and I won't reply anymore
[Sprint Samsung Galaxy Note 3] es0tericcha0s:
So you ask questions and then say you have a life and don't want to reply anymore? :confused: Yea, ok.

Do I remember the firmwares they were on? Yes, actually I do and I also keep notes for further review or if I need to do another one and need a refresher.

For someone so insistent on everyone else reading and understanding things, you somehow failed to notice that I mentioned that I had previously unlocked one with the MI3 modem so your comment was completely pointless and way off base.

I was in no way complaining that it was not working, just that it did not work for me. If you don't understand the importance of this kind of information pertaining to which updates and modems play nice together then you're in the wrong place and aren't helping anyone.

PS. You can't always just follow the OP and expect everything to work right, especially since there have been many updates to the software and firmware since the OP posted the guide and last edited it thus there is no way to cover every little combination of things. These kinds of things matter and not addressing them creates confusion for newcomers who are trying to do this.
[Sprint Samsung Galaxy Note 3] bawanyh:
I dont know if this has been discussed, but I have couple of Note 3s that are on 4.4.4 and when I flash MI3 modem it keeps rebooting after turning on. Any help would be appreciated.
[Sprint Samsung Galaxy Note 3] Mrhunter13:
that has already been talked about ..just go bk a few pages to find the answer
[Sprint Samsung Galaxy Note 3] es0tericcha0s:
I just odin the NAB update for the Note 3s that do that. Then the MI3 modem won't make it reboot. This seems to affect some Notes but not others without much rhyme or reason it seems. I've had it happen on 1 and not another and both were on the same update before. Once I went down to NAB then everything went smoothly from there.
[Sprint Samsung Galaxy Note 3] doantri:
Hi

I need good nvm or qcn dump from wotking phone because i need restore my phone to orginal status.

Thanks for a help
[Sprint Samsung Galaxy Note 3] es0tericcha0s:
Reflash stock firmware and dial ##SCRTN#
[Sprint Samsung Galaxy Note 3] iBowToAndroid:
NC2 also works, for anyone that wants it for whatever reason
[Sprint Samsung Galaxy Note 3] okanee:
Anyone happen to know (or could quickly test) if the Note 3 included Sprint SIM will actually register on GSM footprint in the US - once the regional locks are removed as per the OP, as a roamer on any of the US GSM network and be able to make calls, receive SMS etc? (same as if in Sprint International mode)
[Sprint Samsung Galaxy Note 3] es0tericcha0s:
Is the title of the thread confusing some how? Or the OP? Or the dozens of people throughout the thread that mentioned it worked for them? How much more proof do you need?
[Sprint Samsung Galaxy Note 3] okanee:
I believe you've misunderstood my question. I understand that the original post is geared to using a U.S. GSM SIM e.g. TMO, AT&T etc in the device while in the U.S which is not otherwise possible since the device knows it is in Sprint CDMA coverage area even while in GSM/UMTS mode (and won't allow that) and that several folks have reported that as working after OP. While I'll admit it's a slight deviation from the intent of the OP but I'm asking about an edge case scenario that comes about as a result of having successfully executed the OP steps i.e. that the original Sprint SIM could in theory roam on to another U.S. GSM network (as it does when international). It's unlikely I know, but after OP success the conditions are there that it could happen - hence my question, as someone might have already noticed that or could test it.
[Sprint Samsung Galaxy Note 3] es0tericcha0s:
I did misunderstand. I apologize if I came off kind of harsh. I'm certain it doesn't work like that, but furthermore, why would you want to? This kind of unlock sets the phone only for GSM and it's not as simple as just switching the SIM back to Sprint and switching the network mode back to CDMA to get service. A SIM specific to the network you choose will work best anyway. Again, sorry for the misunderstanding.
[Sprint Samsung Galaxy Note 3] okanee:
No worries, you're fine. It's a very unlikely scenario but one I was curious to see if it would work or not, and not at all related to the most applicable use of this which is simply to use a TMO/AT&T or other U.S. GSM SIM. I asked because anyone who has been successful with the OP steps may have noticed it or could quite easily test. To some of your last points, I'm not asking to move the device back and forth between GSM and CDMA modes - since the OP steps are probably removing/disabling any CDMA mode in the modem so the device will not know it's in CDMA land when attempting to use a U.S. GSM SIM - but rather just to try the original Sprint SIM while in GSM/UMTS mode post successful OP steps.

SM-N900P on Rogers Canada

Hi all

Had phone Internatiolally unlocked by Sprint (UICC unlock) this morning.

Tried to connect to the network (Rogers Canada) and all I get is a red X on the signal, have tried all possible configs, for the network type with no Joy

Since Rogers is very similar to AT&T I did the steps listed in this thread but still in the same sutiation, even tried to lock the GSM to 850/1900 but still no GSM signal

Any Canuck here who has had the same issue?

Any help would be appreciated.

Current status:

Baseband N900PVUBMI3
[Sprint Samsung Galaxy Note 3] es0tericcha0s:
Try the MJ4 modem. I never had success getting a signal with the MI3 modem. Once I performed the unlock and updated the modem to MJ4, everything started working.
[Sprint Samsung Galaxy Note 3] wycito:
Hi es0tericcha0s

Thank you for you reply

I did have the MJ4 modem on 4.2.2

then downgraded to MI3

I did receive the UICC unlock from Sprint, would changing the modem to MJ4 void the unlock?

Thank you
[Sprint Samsung Galaxy Note 3] es0tericcha0s:
No, you won't lose the unlock. And if you were for some reason, you can use either the Galaxy Tools app or the Sprint Samsung Unlocker app to reunlock the international part (like Sprint does) in 2 seconds.

My success was found on NAB update with MJ4 modem. Have done a few like that now. Can't speak for the older updates so you might have a different situation. Doesn't hurt to try though.
[Sprint Samsung Galaxy Note 3] MattMatt0240:
No, unlock will remain through modem upgrades/downgrades, as well as ROM wipes/installs.
[Sprint Samsung Galaxy Note 3] wycito:
Thank you es0tericcha0s and MattMatt0240

Will downgrade to NAB and re-load MJ4 and give it a go, hopefully it will work get rid of the red X

WIll post once completed, hopefully today
[Sprint Samsung Galaxy Note 3] GEORGE305JD:

i need help samsung galaxy note 3 unlock
[Sprint Samsung Galaxy Note 3] wycito:
Still the same

Hi es0tericcha0s and MattMatt0240

I did flash NAB and loaded MJ4 modem, still same situation, my sim status screen looks exactly the same as the one posted by GEORGE305JD, same red X on the signal, any other sugestions?

No joy with this phone, thinking of selling it to get a 900w8 version to work with Wind mobile Canada and Rogers
[Sprint Samsung Galaxy Note 3] es0tericcha0s:
I unlock NAB with MI3 modem then update to MJ4 modem when finished with unlock. Has worked on multiple devices now.
[Sprint Samsung Galaxy Note 3] vipersinu2:
Read my post 884
[Sprint Samsung Galaxy Note 3] wycito:
Eureka!!

Thank you for all your help, was able to get signal and HSPA+ with Rogers Canada.

Open Galaxy tools and opened the "Testing/Phone info" > Device information > and set the preferred Network type to "GSM auto (PRL) with NAB and MJ4

With time will post all screenshots of my UE settings& info as they did not necesarily match those in the original post.

I know it has been talked before but:

I want to load Cyanogenmod 12 to get ride of Touchwiz alltoguether, does cyanogenmod rewrites the modem in the update?

If it does or does not would I lose my connection to the network and get a red X again?

Anyone has done this, I am on Rogers Canada.
[Sprint Samsung Galaxy Note 3] rbeavers:
It worked. Sprint Note 3, T-Mobile sim. The sim wasn't active so I could only call and text ting.com my provider, data wanted to work.

I used IMEI backup app and saved the settings.

I then restored from TWRP backup to return to sprint. I restored the sprint IMEI from app. Even though the deleted apns didn't restore have voice and texts after phone activated. ; edit x2 I have LTE signal but not data, seem no way to get data working with out a computer.

Then for kicks I restored the GSM IMEI settings and with the T-Mobile Sim I was back on T-Mobile and the apn settings returned also.

I then went back to sprint.

So if you can live with out sprint data you can switch back and forth in a matter of minutes with out computer!

Thanks for the hard work and if I haven't all ready donated it's coming your way. Can't find link...
[Sprint Samsung Galaxy Note 3] lilila:
So I bought an N900P off-ebay, checked ESN with Sprint and was told it's blacklisted. Checked the ESN on some websites, the result is also blacklisted.

Anyway, tried the unlock procedure in OP. I found out two ATT sim cards, one H2O sim card works with the phone.

AS for T-mobile cards, I tried three of them, all failed, with the RED X status: one is still active, the other two not activated yet. I did notice for one of the T-mobile cards, the T-mobile status flashed for one second, then went back to the red X.

To my knowledge, the blocked IMEI lists database is shared among the major operators. Somebody please enlighten me before I return the phone for its bad ESN.
[Sprint Samsung Galaxy Note 3] idone:
Yes it is shared, sometimes the phones just get blocked for specific providers(say Sprint bill wasn't paid), but if it's on the Global Blacklist it won't be good for any network ever... if you have a way to return the device for a refund I would recommend it.
[Sprint Samsung Galaxy Note 3] es0tericcha0s:
Just unlocked another one today for use with T-Mobile, but was unable to get it to work on anything but the GSM only setting. It'll connect sometimes on WCDMA preferred, but will only get Edge data and then will disconnect. GSM only mode works all the time, but of course, Edge data sucks. I've quadrupled checked all the settings and have done a few already, so am very familiar with the process. Just did one the other day for Family Mobile (who uses T-Mo towers) and everything works fine. Any ideas on what causes that? If it works on GSM only mode, it shouldn't have issues on reconnecting in other GSM related network modes, but it does, and horribly so, as it can't even continue to makes calls and texts.
[Sprint Samsung Galaxy Note 3] onemanruler:
Going to gsm blacklisted imei doesnt matter. Gsm and cdma are two different network types. Gsm identifies your phone with the sim card data. Cdma is similar but instead of a interchangeable card its a permanent chip with data that stores your phones full identification info. (Difficult to do but you can spoof a imei from another phone to yours as long as your the owner of both phones and you no longer use the spoofed device. And you are not a cell phone service provider employee. Its illegal for them to modify the contents of any imei device info.) So know before you go.
[Sprint Samsung Galaxy Note 3] idone:
That's bad info, blacklist imei is shared among all providers, worldwide. If the phone is on the global blacklist it is no good on any provider. And yes you can pull up att and tmobile network without a sim in while in GSM mode.

Go read here if you need to http://www.gsma.com/technicalprojects/fraud-security/imei-database but I ASSURE you this is true. Or just test a blacklisted device and find out for yourself.

IMEI certi will fail(if blacklisted) and the phone is no good on any network, even if you ship it overseas. You can check phones on swappa.com, if the problem is an unpaid bill it will likely only be blocked by that provider, if the phone has had an insurance claim for being lost, stolen, or damaged beyond repair it's very likely to end up on the global blacklist.
