[Sprint Samsung Galaxy Note 3] droidzer1:
That's an interesting thought. I do believe that the TWRP backup puts the Modem data all in one file. On mine it's about a 60 Megabyte file. I just got my other Note 3 back today from the buyer. I'd be open to trying something like that but it might be good to hear from ecs87 or anyone with a bit more knowledge than I've got on such a plan. Don't want to hard brick this although I've got some Unbricking files (not sure if those work on a hard brick).

I have a question that just popped to mind. I see quite a lot of Sprint Galaxy Note 3's that have sold on eBay (do advanced search for sold listings) that advertise as having a bad ESN and yet they are selling. I wonder how all those people are fixing them as they are certainly locked with a bad ESN. Unfortunately eBay doesn't let you contact winning bidders anymore like they used to so I can't ask any of them :mad:

Towelroot worked quite well to root my Sprint Note 3 but I don't think that does the same thing as chainfire. No data was lost in that root.
[Sprint Samsung Galaxy Note 3] Mrhunter13:
as far as the esn thing ppl flash there phones to different carriers to get service which is limited to 3g data
[Sprint Samsung Galaxy Note 3] droidzer1:
Yes I guess that's how the one I just got back was working on Cricket after having a bad ESN with Sprint. However the person who bought it to use on T-Mobile returned it to me and said he was unable to get it on T-Mobile. I'm not sure what he requested from them as he is not real knowledgeable on cellular. Depending on who he was talking to the T-Mobile person seeing it as a Sprint phone might not have known it had GSM capability (I had turned on the GSM mode before sending it to him). Anyone know if this should be possible to put on T-Mobile?
[Sprint Samsung Galaxy Note 3] danon.brown:
I just thought about something regarding this. The sprint note 3 doesn't support the lte bands. At least for tmobile which is 1700/2100. Assuming its the same for att. Since the device works on both networks.So you probably will never get the 4g lte.
[Sprint Samsung Galaxy Note 3] droidzer1:
Found another item in Service mode that I wonder if it could be a possible loophole into the Sim Lock issue. Menu choice says "Force EFS_Sync". What does it sync to? Since we can directly edit EFS settings if rooted and there is also an NV Rebuild option in that same menu ... probably just dreaming and showing my ignorance here but I like to question everything I see in that service mode menu.
[Sprint Samsung Galaxy Note 3] droidzer1:
Are you sure about that? I see these LTE options in the Service mode in my Sprint note 3 :

4} LTE Band Preference

6) LTE/WCDMA Mode Only

7) LTE/GSM Mode Only

also one for "LTE Related Settings" and VZW LTE B4 on/off
[Sprint Samsung Galaxy Note 3] danon.brown:
The sprint version only works on 1900 for lte. Gsm will work but no lte.
[Sprint Samsung Galaxy Note 3] Omar04:
Yeah not the same Towelroot roots without changing device status. But chainfire does because he uses anther approach with a recovery. He can do it whith out it but he's pro Sammy and want to Knox x1 and custom status just for the sake of it. Smh! So towelroot best option. IMO
[Sprint Samsung Galaxy Note 3] felipeberberm:
here in mexico there is a person who sells a sprint galaxy note 3 (n900p), I told him that I have one like it and tells me that when I buy it still came locked, assures me buying the code in chronicunlocks i was watching your product and ensure release the note 3 gsm sprint for international use, I'm tempted to buy it but do not want to throw my money, someone knows ?, This is the section where they say unlock sprint samsung phones for international gsm https: // chronicunlocks.com//request/4/samsung-phone-unlock --- purchas

pd: excuse my English but I'm using google translator
[Sprint Samsung Galaxy Note 3] MattMatt0240:
ecs87 has already clarified on the subject. I was hoping maybe there was something in the modem that could communicate with the specific NV item or something, unfortunately, not that easy or it would have already been done. :(
[Sprint Samsung Galaxy Note 3] droidzer1:
Seems I ran across some information recently about Mexican Note 3's being easier to unlock but I might be wrong. However that's an expensive service and they have a warning (quoted below) that makes it clear you need to know it will accept an unlock code because if it doesn't they will NOT refund. Have you tried a foreign SIM card in it yet and does it ask for an unlock code?

"Any Model: $49.99

NOTICE: You are responsible for ensuring that your type of Samsung device accepts unlock codes. Insert your foreign SIM card, and then if it asks to enter an unlock code, this service can be used. If you are not able to test this, it is advised that you do not order, as there are overhead costs involved with acquiring an unlock code and we absolutely will not refund if your device type does not accept unlock codes."
[Sprint Samsung Galaxy Note 3] felipeberberm:
I unlock region and put a sim telcel mexico, simply says "sim not valid" and does not ask me any codes
[Sprint Samsung Galaxy Note 3] ecs87:
Because as mentioned approximately 100 times, Sprint Samsung Android devices do NOT ask for a SIM Unlock code. The lock mechanism instead is in an nv item that's modified by an OTA system.
[Sprint Samsung Galaxy Note 3] droidzer1:
I've been using a Logcat app to search for the unlock password while using the ##3282# on the dialer, going into the Data profile where the AAA password is, opening it and then closing (no change made). From what I've read that AAA password is what is used to unlock the phone and is 16 characters (32 Hex) and I think I find the password but it is encrypted it would seem. It's ascii characters but I can also use a Hex editor to see the Hex code for it. Still encrypted though so probably a waste unless someone knows the decryption used. The Logcat basically records everything the phone is doing and saves it as a text file - sort of like Process Hacker for the PC. In 30 or so seconds of using it I got a 3.2 Megabyte file of data. Thanks to the Note 3's multi-window function it's not hard to do this.

Also used some programs to read the NV ram but I'm not sure what line the password is on and I think someone said it will give 'access denied' anyway to even read it?
[Sprint Samsung Galaxy Note 3] idone:
aaa password is just to get phone authorized for 3g data.
[Sprint Samsung Galaxy Note 3] ecs87:
[MENTION=319373]idone[/MENTION] is right. No clue why you're looking at the 32 character AAA password. It's just for data authentication. The EFS password is in hex but is 16 characters (and it's in the modem, you won't find it in any logcat). I'd suggest stopping now before you mess up a parameter that stops you from getting data altogether (yes it can do that!). If you mess up your AAA password there's only one way to get it back.
[Sprint Samsung Galaxy Note 3] droidzer1:
I didn't change anything and exploring and learning is my game. This is a Galaxy Note 3 I got for $100 ! (deal of the year! although I did replace the S-Pen, the back cover and the Camera Lens cover - total $18 in parts) so if I mess something up it is not a huge loss but I am careful in what I do generally.

What I have learned today... A way to actually ENTER the Unlock code if I can find it. And I'm working with any number of hundreds of Forensics programs, IDA (Interactive DisAssembler) and some other unique programs that I am finding can extract info from the Modem. I was loading the roughly 60 Megabyte Modem image into IDA but I need a little more time to get that right. As far as the AAA password that was something someone on another forum mentioned but I am guessing you know more about this than he did.

So this phone is useless now except as a Wifi Phone and handheld computer and it is a second Note 3 for me. I am trying to figure this out for myself and anyone else that would benefit for a method to unlock Sprint's SIM lock. You don't work for Sprint do you ? Just saying I could see why you might want me to stop if you were but please don't worry about me messing up the phone. I take full responsibility for any mistakes I make although I doubt anything I do through playing with data can't be undone by some method. I do appreciate the help you have given. :good:
[Sprint Samsung Galaxy Note 3] droidzer1:
Get the latest Phone INFO ★Samsung★ v1.90 . Big additions from v1.86. Start the App then click Menu key on Note 3 and choose Secret Codes. These were not in the previous version. You'll get a huge list of codes which in the past many have worked from the Phone dialer but in recent times many have been blocked or no longer work. However with this app once you are in secret codes touch on one of them (Perso codes in the 746xxxxxxxxx range are where you may want to look for the Network Unlock choices). Then after you click one a menu pops up which gives you a choice of using the Phone dialer (Launch 2) or Launch 0 (which I believe is Profile 0 and the one you want) or Lauch 1 or 4. Based on this choice and where it is asking for the Network lock code it appears that code is ALL Numerical. Based on a string of 16 ascii characters I found in the modem (obviously encrypted) around the Perso I believe by the fact that several of the ascii characters were duplicated and there were less than 10 different ones that this is the unlock code encrypted. That's my best guess anyway at this point.
[Sprint Samsung Galaxy Note 3] droidzer1:
Some unassembled code from the modem:

[SPR SIM LOCK ]Test ICCID mmgsdi_card_init.c:[SPR SIM LOCK] Test SIM mmgsdi_card_init.c:[SPR SIM LOCK] SIM LOCK = %d, 0 : LOCK, 1 : UNLOCK

The variable %d would seem to set to either 0 or 1 and 1 would seem to be the UNLOCK state we want. In the past I've been able to hack files with a HEX editor and change variables to set numbers. If that could work on this then it just might get by the need for the unlock code. Problems could arise though if the entire modem file has a checksum that needs to match something saved elsewhere.
[Sprint Samsung Galaxy Note 3] ecs87:
I'm DEFINITELY not trying to steer you away from the unlock. Just don't want you to mess up your device if it's still functional. I know quite a few people would be mad if they messed up their day to day phone.

I already tried altering things in the modem. If you even change a 0 to a 1 or vice versa it'll fail in Odin and if you try forcing it through adb you'll get an unknown baseband. I've seen what you're talking about in the modem and documented it here on xda.
[Sprint Samsung Galaxy Note 3] droidzer1:
A true HEX editor is what I'm using to edit the modem.emmc.win from TWRP backups. I am thinking about editing it and then restoring it from TWRP. Using a HEX editor usually keeps things good to go if you make minor changes. I'm just not sure if TWRP will complain - I'm removing the MD5 checksum files so that won't be a problem and the other potential problems I see is whether my swapping the 1's and 0's will do anything at all and whether the phone has a checksum for that modem file that would complain.

---------- Post added at 09:57 PM ---------- Previous post was at 09:42 PM ----------

Thanks for the concern. I never mess with my primary phone ... well other than rooting. Both my Note 3's are non-active on any cell service currently. Both were Sprint and both SIM locked. The one I'm working on now was on Cricket even though it was SIM locked so I assume it was probably on Cricket through Verizon. It seems most Sprint Note 3's are somehow able to be put on Cricket. And this one even had a bad ESN (one of the reasons I got it so cheap).
[Sprint Samsung Galaxy Note 3] droidzer1:
Well this is WEIRD. In the meantime I decided to flash the Galaxy S5 port to the Note 3 of the M.O.A.R. ROM to this Note 3. Awesome ROM! Played with it a little then went to restore my regular ROM - now I have not made ANY changes to the Modem file YET. I am just doing a TWRP restore (latest TWRP 2.7.1.0) and it seems to be hung on restoring the Modem. I guess the Modem heard what I was going to try doing to it :eek: That M.O.A.R version is 4.4.2 just like my original ROM.
[Sprint Samsung Galaxy Note 3] droidzer1:
Weird but no real problem. I ended up fixing that issue by restoring the M.O.A.R modem to the stock ROM and it works fine.

THIS COULD BE VERY GOOD NEWS - See below:

So next I Modify that Modem swapping the 1 and 0 in that SIM lock area with my HEX editor and save it back to the TWRP modem backup. I then restore that Modem and NOW I'm NOT getting an "Invalid SIM card" notice! However before we get out the party horns I've got to think that all I did so far was probably stop that message from showing up - maybe. That and I proved I can MODIFY THE MODEM successfully without it crashing anything and everything seems to be working fine. I am currently using a non-active non-Sprint SIM in it but I do have a Ptel SIM that is active and I'll be trying that one. The only issue with that SIM is I can't really test it without driving about 40 miles since I'm so far from a GSM area.

---------- Post added at 01:28 AM ---------- Previous post was at 12:57 AM ----------

DARN!! I spoke too soon. Good news / Bad news. Good news is that the way I modified the Modem works and no problems. But the bad news is that I first tried this on the MOAR Rom and didn't see "Invalid SIM card" because the ROM doesn't have that message (I think there is a little symbol in the notifications that may have been the invalid sim notice rather than a text message). However when I put the modified modem into my stock ROM it came up fine with no problems but it is saying "Invalid SIM card". Other good news - I won't be driving 40 miles to test that Ptel SIM :rolleyes:

On the other hand there might still be hope for that change as I don't recall if NOT changing any of the APN settings would cause the 'Invalid SIM' message. Any one know off hand?
[Sprint Samsung Galaxy Note 3] droidzer1:
Well I was wrong about being wrong - LOL. What I thought was a invalid sim icon was not. So the MOAR Rom simply does not show any 'invalid sim message' anywhere even when I use the unmodded Modem in it. Might have to do with some other setting or the notification for that isn't in this ROM. I'll continue trying some other changes to the modem by this method. I think the difference between using a HEX editor and some standard editor or text editor as may be in Odin or ADB is that the HEX editors maintain the integrity of the file. I'm not sure I can explain it but I've used regular editors in the past to hack files and that always produced a fail or some problem where HEX editors did not cause this sort of problem (unless of course you mangle the code so badly things don't work).
[Sprint Samsung Galaxy Note 3] ecs87:
Have you swapped the 1 and 0 in the modem and tried launching a stock touchwiz rom? I was using Winhex. It ended up flagging the modem as unknown if loaded through adb. You can confirm that the phone has your modified modem by pulling mmcblk0p2.
[Sprint Samsung Galaxy Note 3] idone:
Changing one nibble here and phone doesn't boot. "Secure Watchdog Bite" had to odin modem back.

I changed these directly on phone partition 0x30 to 0x31 and vice versa.

I have gotten my phone to the hidden menu editor part. but cant figure out how to even open the hidden menu enabler at all. can someone help me with this part, please.
[Sprint Samsung Galaxy Note 3] idone:
You can launch IOTHIDDENMENU with this apk if you have root.

Also you can change sales code and mps code to make apns open editable without providing spc. A reboot is required after changing them for apns to become editable.

Teella, Glad to see you were able to use this. Simple and quick and no need to install another app. Works on many other phones too. I was beginning to think no one had noticed that post or no one tried it :) I got that info on another forum but finally did run across it in one place here on XDA somewhere recently. Nothing slips by XDA forums ;)

I haven't given up on modding the Modem here - just got sidetracked on some other things this week.

ecs87, yes I ran it on a standard Touchwiz ROM and yes it works and I've double checked the file to verify that the 1 and 0 were indeed swapped. I've got both the stock and modded ones on my PC in separate folders so I can always reload the stock one if needed. and backups of backups always :cool:

AFAIK, only Sprint and Apple phones can be unlocked OTA. Not saying that there is ZERO possibility of unlocking any other phone OTA, as I do believe all phones now have that capability; but retail unlockers are still offering codes.

User beware. They could just be collecting information and IMEIs.

hey to unlock this thing you need to use the at commands, only way its done no modding the modem will do on this you have to unlock the nvitems with at commands.

2) Will I still be unlocked on AOSP ROMs?

3) are we still not able to downgrade from 4.4?

Wife's phone is having a few problems and wanted to put a asop rom in the phone as well. But I have the same questions you do. Don't want to upgrade if it loses all the GSM settings you posted. Any update on these questions?

Can you do a factory reset without losing the settings?

She is having GPS issues.
[Sprint Samsung Galaxy Note 3] MattMatt0240:
I flashed NC5 when I unlocked, with mi3 modem. After a week or 2, I couldnt stand stock anymore, and went to KitKatKiller. Had to put APN settings again, but had service once again.

Now, this ROM is not being updated and is still at 4.2. I want to upgrade to 4.4 but of course, don't want to lose unlocked capabilities. Maybe if the ROM doesn't overwrite modem partition?

3G LTE ON Tmobile

Hello,

I am having an international unlocked Sprint Note 3. I am using it in India.

After performing domestic unlock, can the Phone be used on TMOBILE in USA? Tmobile website says that 3g will be supported only on 1700 mhz phones while I think sprint note 3 does not support 1700 mhz.

Please advise.

I have all info-Please Help

First, you guys are amazing and I wish you could all be as lucky as I seem to be right now.

I switched to TMobile a few months ago after being a sprint customer for 5 years because I moved from philly to the NYC suburbs and the LTE is awful for sprint there. I was on a month to month plan with a S3 I paid to have unlocked from at&t, then came across a clean esn note 3 for sprint on craigslist. i fell in love immediately. I tried getting MSL through all of the tricks suggested (programmer/travel) and even put on the tablet line i still have with sprint...they wouldnt give to me. I deactivated it from the line I have to clean the ESN and went to a store in Philly which has the best, most knowledgeable, and helpful customer service person I have ever met in the cell phone industry. I used to spend hours just talking about specs and roms with him...I have rooted, backed up, but only done one successful flash so am by no means experienced. I ended up buying a note 3 from tmobile 3 days ago and told him my story. He asked one of his tech people-i had the MSL code 2 minutes later. I went to ##DATA# and entered it where it said edit...it is good. I called sprint interational to find out how to unlock it once i had code-they, just like all of you experienced, are [MENTION=5171255]holes[/MENTION] and hung up on me.

I have a clean ESN, a good MSL code, and just need to know where to enter it to internationally unlock the phone so I can proceed. I don't want to put the store and name of the guy on here but if you email me at mroberts zero nine zero three at gmail.com I will call him to see how I can connect you guys if you can help. When I go to the UICC Unlock I get a message that the phone needs to be reset. I have the hardest part of this done, just need to know how to proceed. This will save me a lot of money because i can return the n900T and if the note 4 turns out to be incredible for some reason....the specs didn't overwhlem me between the two, I can use this to trade it in down the line. I paid half cash for the tomobile phone to be able to jump whenever and they wouldnt buy the sprint phone because there was a small pink hue on battery. I just need the correct ##_# i am assuming. It is much appreciated. Than you in advance
