I use a samsung captivate that was locked to Rogers. And now I am running it on Fido
I have been having issues connecting to 3G for over 6 months now. I completely gave up on the idea and lived off 2G, until someone suggested that I had unlocked my improperly. I believe this to be the root of my problems. I need to figure out how to lock my phone, and then if I can unlock it it properly, all my problems will be solved. PLEASE HELP. I will now try and explain all the different methods that I have used
The method I used initially was by extracting nv_data.bin file and using a hex editor to edit it to unlock. This did work, and my phone was working perfectly. But on a ROM update my 3G connectivity issues started.
I have to explicitly state 'only 2G' on my network connections, otherwise I lose my voice connection as well (because somehow the voice connections runs over the data connection - and one wont work with the other)
I decided to unlock properly - by buying a code off ebay. The code is based on the IMEI number of the phone.
I tried locking the phone by entering *7465625*638*# and entered
302720 (mnc/mcc for rogers)
and my purchased nck code
the phone even states that the lock code was successful. But on inserting my fido SIM, my phone acts like it did before - i.e. voice connection does work unless I explicitly select '2G only'
Initially I also tried locking by reediting nv_data.bin file using a hex editor. The instructions state editing the address '0x181468' on the file. There are 5 different bytes representing different locks (network lock, subset lock, sp lock, cp lock, data lock) and they are represented in binary. On just changing 'network lock' to 01 to phone acts the same. But on changing all the values on all the bytes the phone locks and asks for an unlock code on restart - but the purchased nck code does not work
This is over 6 months of trial and error, so I apologize if I am all over the place. Please provide any suggestions and I will clarify as soon as I can
This is NOT in relation to changing IMEI/ESN as that is ILLEGAL! This thread is about enabling our baseband/modems to operate on different frequencies/couriers.
Trying the VZW unlock thread first HERE
I'm flashing a VZW ROM right now to check APN menu, etc. Sprint even with hack doesn't show APN.
There are several threads on how to unlock Verizon/Tmobile/ATT modems to work on each other with varying levels of success. I feel that we have a iPhone 4s/5 like device that has the same chipset just different locks around the software to prevent unlocking. I was moved by the community's involvement in adding a SIM card slot to the Note 2 and want this mod to work on US couriers.
Basically put, I want to make any US variant S3/Note 2 an international version. The hardware is the same, it's the NVRAM/Firmware prohibiting us.
This is the SIM card mod for the SPR N2:

The primary method of unlocking modem bands is flashing a QCN file that modifies NVRAM params. In the ATT T-Mobile thread the hack works by flashing over a ESN/IMEI stripped T-Mobile qcn backup file.
I tried following this process but was blocked by a "Roaming Lists could not be read" error at 16% when trying to backup my NVRAM using QPST. I attempted flashing the file anyway and received a "Could not Communicate in Diagnostic Mode" error. My modem then would not see any networks. I then flashed a ATT modem which bootlooped my device.
I feel the Roaming List could not be read is the main issue into how Sprint locked down this device for US GSM. In SIM tech, the courier provides a preferred list of up to 80 couriers the phone is to connect to first when roaming due to courier roaming agreements instead of the strongest signal first. As the Spr model uses a chip for a SIM it's possible that the "SIM" could not be read to provide roaming lists and GSM could be blacklisted in this chip as it is more sophisticated then a SIM smartcard. Now that I flashed a ATT modem I'm going to try to download the NVItems again using QPST.
I restored my TWRP backup and sideloaded a SPR modem, back at stock all working.
The alternative is to use the "IMEI/ESN" backup tool:

I will continue experimenting and will report progress.
When writing back my NVRAM dump I get this list of readonly/locked items:

Mobile networks show a previously unselectable item WCDMA only as selected which is not in the menu, the network status is unknown. I have a feeling the nv-item is trying to reference a menu item that is not in my ROM.
Next I'm going to ODIN the stock ATT rom over and see what happens.

Trying new international ATT rom. CM10 didn't have what I needed for network selections.
I have successfully detected a GSM network type although it's going to need some work.. I got to go home and eat.
1/11/13 11:14am
Using the RF NV editor from QPST I can edit all NV-Items with no roaming lists error.
BY FOLLOWING THESE INSTRUCTIONS YOU ARE INTENTIONALLY BRICKING YOUR DEVICE. I HAVE TESTED RECOVERY BACK TO STOCK WITH A ODIN FLASH AND RESTORATION OF MY NV-ITEMS BACKUP. I TAKE NO RESPONSIBILITY FOR YOUR DEVICE AND THESE INSTRUCTIONS ARE PROVIDED AS-IS.
That being said I have ODIN flashshed ATT firmwares over, international firmwares over, changed numerous NVItems settings and have been successful in restoring my device to fully operational stock with working radio/service. At one point I had to go into download mode and odin TWRP and ADB sideload a modem due to a boot loop but I was still able to recover.
*DO NOT PROCEED UNLESS YOU ARE AWARE OF HOW TO UNBRICK YOUR DEVICE AND RESTORE IMEI/NV-ITEMS*
To enable USB file transfer at anytime dial *#7284# Qualcomm USB Settings and select MTP+ADB
Here is a howto/recap of what I have accomplished:
**YOU MUST BE ROOTED**
You need the SIM card board for this to work otherwise you are simply experimenting. Get one HERE
1. Get the Note 2 toolkit and drivers per your device HERE This is the easiest method of getting all required tools/software for a brick restore and other flashes.
2. Get the Samsung NV Items tool HERE
3. Get your MSL using the *root required* Get my MSL app HERE Write it down and keep it in a safe place!
4. Dial *#7284# go to Qualcomm USB Settings and select RNDIS+DM+MODEM
5. Plug or Replug your device and wait for drivers to install
6. Open Device Manager and expand Ports (COM & LPT) (windows xp/7/8), make a note of which COM SAMSUNG Mobile USB Serial Port (COM*) (If you do not see the port listed then you didn't install drivers, wait for driver install or you didn't enable Qualcomm diag properly)
7. Open NV-items_reader_writer.exe and select your COM* from Port: dropdown. Put your MSL # in where it says 000000. Make sure BOTH checkboxes are checked and click connect. Click Read. Should say in console "Log message: > SPC is correct. Phone unlocked".
If you get "Log message: > Phone does not accept SPC. SPC is not correct" then try 000000 as MSL
8. Click Read and wait 5-10 mins for your nvitems to be read. SAVE THE TEXT FILE somewhere where you won't loose it and MAKE A BACKUP. Email it to yourself and upload it to dropbox. If you loose this file then you could permabrick your device!
9. Download the AWS ATT NvItems unlock file HERE Click DOWNLOAD and save the txt file to your desktop or somewhere where you will remember.
10. Open or go to NV-items_reader_writer.exe. Do the connect, MSL, read and select com port if you closed the app. Click WRITE and select the text file you downloaded in step 9 "nv aftr qxdm removed imei.txt". After writing click on Mode and Reboot or simply reboot your phone.
At this point you are on a Sprint Rom/Kernel/Modem with a GSM compatible radio. Your Sprint software has no idea what is going on and most likely won't connect to GSM even with a SIM card inserted. If you go into Settings->Mobile networks you wont see options to set APN. This is because the Sprint ROM/Radio isn't setup to connect to GSM. Try THIS to "unlock" US GSM couriers on Sprint ROM
11. Flash this ATT ROM: (others may work, although you need a ROM with NO included Kernel/Modem)
HERE
This is the [ROM][4.1.2][XXDLL1] Asylum TJ v1ROM with no modem/kernel/etc. Wipe Dalvik, factory reset, cache. I also wiped system before installing but you may not need to.
12. Boot and verify the rom boots.
At this point you can experiment with the Mobile Networks settings and should see APN options. Change your Network mode and see if you can get any listings for "Network operators" when selecting manual. If you can see ATT/T-MOBILE then report your findings!
13. Next is to flash over a ATT modem/radio in TWRP. Download the modem HERE
THIS MODEM WILL CAUSE YOUR DEVICE TO BOOT LOOP. Although I found on my device it only rebooted every 5 mins or so.
14. After booting you should be able to see ATT/TMOBILE in your network operators settings. Make sure to play with Network mode. I don't have a SIM card and so my lockscreen said "Emergency Calls Only" and I couldn't get into the Mobile Networks menu as it told me to "Please insert SIM card"
At this step I'm fairly certian the GSM bands are unlocked as most people only see Emergency Calls Only when their device is not registered. Normally this is caused by invalid or unauthorized SIM/IMEI/APN settings on a normal GSM phone.
RECOVERY
1. Download Sprint firmware HERE
2. Extract the ZIP to your desktop so you have the "COMBINATION_L900VPLJ1_L900VPALJ1_CL265523_HWID04_HW-Rev0406_user_low_ship.tar.md5" file on your desktop
3. Go into download mode HOW TO
4. Open Odin from C:\Samsung Galaxy Note2 ToolKit\Odin3_v3.07.exe
5. Connect your device
6. Click PDA and select "COMBINATION_L900VPLJ1_L900VPALJ1_CL265523_HWID04_HW-Rev0406_user_low_ship.tar.md5"
It will check MD5 and it'll take a minute
7. Click Start and wait for your device to flash & reboot.
8. Dial *#7284# and go to Qualcomm USB Settings and select RNDIS+DM+MODEM.
9. Open NV-items_reader_writer.exe
10. Find your COM port from earlier in your device manager, same as last time
11. Connect, Read. IF YOU GET SPC ERROR TYPE YOUR MSL or TRY 000000
12. Click Write and select your NV-ITEMS BACKUP .txt FILE
13. After writing click on Mode and Reboot or simply reboot your phone.
14. Dial *#7284# Qualcomm USB Settings and select MTP+ADB
You should now have a fully operational Stock device.
To enable USB file transfer at anytime dial *#7284# Qualcomm USB Settings and select MTP+ADB
If you have issues past this point then you didn't follow instructions completely or you experienced something different then what I experienced. The most important step of unbricking is restoring your NV-ITEMS. Odin flashing of stock firmware/etc is normal procedures as per any unbrick. You are welcome to try modifying the ATT modem to not bootloop (most likely LTE issues as Sprint radio doesn't operate on ATT LTE frequencies) by following THIS post. You can also try the Sprint ROM/Modem by following the Verizon APN/Network hack HERE
Some roms won't let you do *#7284# for ADB/MTP. The way around this (if you need to transfer files and MTP isnt anabled) is to sideload files from TWRP or find the verizon method for dialer codes for Qualcomm USB settings menu. There was a dialer only instruction post but I can't find it now. If all else fails then simply ODIN to stock.
Impressive work you are attempting. It would def be cool to have the same radio functionality that Iphone 5 peeps have. I am on AT&T, but it would be cool to be able to load the CDMA and related stuff to a GSM phone as well. Good luck, I will be foloowing your thread, mostly out of curiosity.

Great news! Excellent work by the way, would love to see this end up working!
I can now run a ATT flashed modem. When selecting Mobile Networks it tells me to insert a sim card. I'm getting reboots every 3-5 minutes but I think it's kernel related. The ROM is half the battle, ATT modem boot looped on SPR ROM. I should be able to connect to GSM once I do the SIM hack for proof of concept.
Recap:
NV-Items of the ATT to T-Mobile flashed (AWS/GSM unlock, use both ATT and Tmobile on ATT GN2)
Flashed ATT ROM
Failed flashing ATT Persues kernel (stuck at samsung logo)
Flashed Sprint Persues kernel
Flashed ATT modem
I desperately need the NV-ITEMS from an international phone in txt format.

this may have nothing to do with what your doing but ill ask anyway I ported a verizon note 2 rom over to sprint galaxy note 2 and everything works but LTE is it possible to get it to work? Its the JellyBeans Rom in the sprint forum
From my understanding the customization of the chipset is in relation to LTE frequencies which are hawdware related. It's the same for the Nexus 4, it supports LTE unofficially on band 4 due to LG keeping in their Optimus LTE chip. Nexus 4 on LTE only works in certain areas in the country due to ATT only providing LTE band 4 in very limited areas.
I doubt I can "unlock" to the point where a Sprint/Verizon phone can see each other's LTE frequencies as LTE is a different chip in question (most frequently) as LTE courier customization is specific to the courier/device.
I may be wrong as it depends on the chip in question and how it's implemented. I need to find a photo of both Sprint/Verizon mainboards and compare. My work focuses on GSM/AWS bands for HSDPA+ and 3G as it is more likely to work as the chipset known supports these bands. Please feel free to post pics of the boards or chipset info and I'll look into it.
Due to my NV-Items trick I now can use QPST to dump a full nvitems+more. I cannot restore items though
When in GSM mode I'm getting an Emergency Calls Only/Enter SIM which means it should work with a SIM chip.
ATT modem + ATT/AWS nvitems unlock on ATT ROM; SPR Kernel.
Buying a cracked screen working ATT Note 2 sometime today for $325 for additional testing

Agreed, my goal is to get HSDPA GSM data working on Sprint Note 2. Verizon allready has a method of unlocking http://forum.xda-developers.com/showthread.php?t=2044449. I do agree that it's impossible for LTE to work on any method as LTE chip is a whole different ballgame than what I'm attempting. It may be possible but someone would have to start by getting a VZW and SPR mainboard and comparing chips. Even if you somehow get the radio working you would might need to hack the ESN which is ILLEGAL, although VZW does use SIM cards..
However I can see VZW frequencies on my Note 2 right now. Alternating between EVDOa and eHRPD.

Yup, modifying ESN has absolutely nothing to do with my research. My goal is to utilize a provider's SIM on GSM to connect to ATT/TMobile with stock IMEI/ESN. Verizon uses a SIM in their Note2/S3 in which if they accept your ESN/IMEI with their SIM is their discretion. ESN/IMEI, etc is stored in NV Items which is in the modem baseband, not the ASIC. Swapping SIM cards are perfectly legal so removal/replacement of the embedded SIM is legal. ESN/IMEI is like a car's VIN which is illegal to touch, SIM is more like a license plate on a car. I'm a firm believer in its your device do what you want but once you enable your modem to interact with the public infrastructure you are bound to it's rules, period.
On another note I have a ATT Note 2 now but I sold the Sprint Note 2 to get the Nexus 4. I can continue my research into GSM on my Sprint S3 and provide dumps for the ATT Note 2.
I'm fairly certain that I have accomplished a US GSM unlock on my Sprint Note 2 as it exhibits the same symptoms as a Unlocked phone without a SIM, Emergency Calls Only. However I do not see ATT/T-Mobile in my network operators menu which I'm sure the VZW APN hack will fix or it's because I don't have a SIM.
It's going to take someone with a Sprint S3/Note 2 with SIM mod and some tinkering around to get this to work. I'll get a SIM board for my S3 but it's going to take some time as I'm busy with work and my girlfriend. If anything was learned, it was that the S3/Note 2 is pretty much damn near unbrickable. I've flashed every firmware known to man, trashed my NV ITEMS, wiped my ESN/MSL and recovered to absolutely working activationable stock. Don't be afraid to experiment, just BACKUP and BACKUP your BACKUPS.
I am stuck at this step:

THIS MODEM WILL CAUSE YOUR DEVICE TO BOOT LOOP. Although I found on my device it only rebooted every 5 mins or so.
It does cases boot loop, only it's not every 5 minutes, but instantenious, right after "Android is upgrading" Am i missing something?
Update: with ATT ROM, it does give me 2-3 minutes before reboot, however it won't see the Sprint SIM with ATT modem file. I've also tried few other modems from Verizon and some other GN2 carriers, same story. currently i have no SIM mode installed, but I think it should still see SPRINT chip/SIM because it is emmulating a LTE/GSM SIM. SIM manager says SIM state unknown.
Is this the same for you? how are you able to see the T-mobile and AT&T , if you can't get n to the mobile networks menu?

I am using a HTC One V CDMA (Virgin Mobile USA) in India on Reliance CDMA network. The phone was flashed to Reliance and everything is working fine ie I can make/receive calls/sms etc. 1x / EVDO credentials have already been written to the phone.
Now the issue is that I am not able to enable data or the data connection doesn't get enabled automatically. When I try to enable data it says "Disconnected because service is unavailable". But if I press the "Activate this device" button in the settings section, an activation screen 1..2..3 comes up, then wait for 3-4 sec, the 3G symbol gets displayed meaning its able to make a data connection. Now if I go back to the settings page and enable data it successfully connects, and I am able to access internet at EVDO speeds. But after some idle time, the data connection is automatically disconnected and to reconnect I need to repeat the above process. Even if I intentionally disconnect data and try to reconnect, it doesn't happen and I need to go through the "Activate this device" process.
I believe some sort of initialization is missing which is done during the "Activate this device" phase and hence I am able to connect. What could be the reason for this? Is it some setting/configuration that needs to be enabled?
Please pour your valuable tips to resolve this issue.
Thanks
Fixed the issue with auto connection of data, not sure what fixed it exactly, but here are the last changes that I made after which it started working.
You need to use the tool QPST (I used version 2.7.378, an older version didn't work) for this.
In the M.IP tab, disable all profiles except profile 1
Then edit profile 1 and make changes (check attachment)
Then in RmNet tab enable auto connect for device 0 and 1.
After that
PPP Config --> Um --> Enter user/pass as "net" (Req Pw enc should be unchecked)
PPP Config --> AN --> Enter the EVDO credentials given by the MEID registrar (Req Pw enc should be unchecked)
Please note that I got it working merely by trial and error and some of the above changes may not be required and I am not even sure why they are necessary , but with the above configuration I am able to enable data without any problem.

Well, I had loaded the NVDump earlier, but as I had mentioned it would connect first but if you disconnect or get disconnected it wouldn't reconnect.
Check if the SPC is correct, cause I never got any error like that.

OP, I am taking a HTC One V for my dad and plan to use it with reliance, could you please tell me what I need to do ?
I already unlocked and rooted the phone. Do I just walk into a reliance store or do something more on computer etc before going there ?

You are talking about Reliance CDMA right?
If yes you need to get the MEID registered, will cost you about Rs 500. Reliance store guys will not do it, have to get it done through some 3rd party provider.
It says Read only NV Items for me too

Without the correct EVDO credentials, you won't be able to get EVDO speeds. You need to check with your MEID registrar.
NV dump is not really required and the same can be configured manually if you have the credentials as I have described above. Since you are able to make and receive calls, it looks like the Akey is already set.
so that means if i dont get the credentials from the registrar EVDO can never be started on this handset??

You could check with some other person who does MEID registration, maybe they can retrieve the credentials. But without it, EVDO will not work.

Simply by loading the Reliance PRL file, you should have voice signal, if not you are doing something wrong.

I don't think that would be a problem.
Make sure you are using the right PRL file.
No above steps required.
You must have flashed NV Dump already.
Your phone must be activated via *228 already.
Just perform below mentioned steps :
1) Put your phone in Diag Mode by dialing ##3424#
2) Get HTC Diag Mode driver if you don't have it already
3) Download DFS Demo version from DFS Website
4) Connect your phone with DFS, send SPC
5) Now, go to Programming tab -> Data ->
6) Click Read
7) At PPP tab, write "net" (without quotes) to SIP NAI, UID, Pwd field.
Restart the device and here you go, your device would get connected to internet instantly.

Keval,
I recently bought a HTC One E8 and am using Reliance CDMA on Slot-1 and facing this issue.
Would the steps jotted by you help me?
Thanks,
Vinay
I have a rooted and bumped LG G3 D855. I have been investigating enabling additional LTE bands using QXDM, QPST, CDMA workshop, etc. and have accidentally changed my SPC code. Initially the phone would accept the default SPC of 000000 but now it will not. I have an EFS backup from TWRP. Can anyone help me examine these files to determine my "new" SPC code?
I can still continue my LTE work using QXDM since I can still write to certain NV items without the SPC code but I would still like to recover it.
Hello,
i have some problem with my nexus 5Xwith cyanogenmod 13.
Problem was started when i download application Field Test for Nexus 5x/6p
In lte data menu i try change LTE On/Off and change disable and enable band 26 and 41.
From this time all LTE not working. - maybe some parameters was change in modem.
Serveral times i try reflash original rom and CM13 and reflash radio...
I install application QPST and QXDM and in NV browser i have on line : 06828 and 06829 value : 1786875150815
I dont now if this value is correct, but if i try put new value according NV calculator or some numbers from this forum, whitch i found. New values is saved in phone only while i make reboot the phone and LTE still not working.
Backup original NV values i dont have.
Can somebody help me please ?
Thank you
Thank you ...

Just a quick question. Why were you trying to change LTE On/Off in the Engineering Screen? Were you only trying to enable LTE bands or did you have a problem with your data connection? If you were having data problems before downloading the Field Test app, did you know there are some know data issues with CM13. Did you lose your LTE connection?
Also, what gave you the idea to download QPST & QDXM? Do you have prior experience with these applications?
Also, since you have CM13 installed on your 5x, did you try and restore a backup in TWRP that you have saved to see if it corrected your problem?
Which carrier are you with?

Hello,
thank you for your answare, and sorry for my english.
Before problem phone was new and all was worked, but i tryed make some changes, because i searching solution for changng band and editing priority for diferrent LTE band.
Now my problem with no connection on lte is solve, i write zeros to partition modem1 and modem2 from modem filesystem and modem itself after restart phone reset factory setting, but i dont now where modem took IMEI, because i think IMEI is save on this partition...
-----------------------------------------------------------------------------------------------------------------------------------------------------------
But i still dont understed why, after reboot changes on line ID 06828 and ID 06829 comming back originaly number .
Bestest solution for me wold be if i find in NV parameter band priority according signal strenght. Or some application (IN Phone) for disabling and enabling all LTE band without computer.
My most-used bands is : 800,1800,2600Mhz

Shortcut Master Lite in the Play Store will allow you to access the LTE Engineering to set band priority. Open the app and click the 3-dot menu In the top right corner. Click on "secret code explorer" and allow the list to populate. You will be looking for a numbered code like "3282” or "33284". Click on each one, select explore from the menu and look thru each selection. The one you will be looking for will say something like Sprint LTE bands editor. You can enable bands 25, 26 & 41 and set band priority. When asked to enter your MSL, enter 000000 and tap verify. You can figure the app out. It takes a little time to get used to how the app works. Good luck and let me know if you need any more help.
P.S. I dont know why you would start changing NV values without any experience using QPST & QDXM. You can make a mistake very easily. Be careful when making changes. I would start fresh by fastboot flashing the factory images, bootloader and radio and start over. Just my opinion.
What carrier are you with and where are you located?

Why i start Edit without experience ? It is easy, because i need get experience
Band 25,26 And 41 is not important for me.
I need disable and enable and set priority for 800 1800 and 2600mhz, quickly from the phone...
My location is czech republic and switzerland.
