This is exactly why you shouldn't mix and match system versions, modem/baseband versions, kernels, bootloaders, etc. It just ends up being a huge hassle in the end. Go back to the same version of everything that your bootloader is on. Do a ##72786#. Look at your EFS and carrier folders after rooting the phone and enabling root explorer in ES file explorer. Are all the files there? Specifically in the carrier folder you should see 4 files and a folder.
[Sprint Samsung Galaxy S 4 General] rsngfrce:
ecs87, your reply is to me, correct? I appreciate greatly ANY suggestions that are made, don't doubt it, even if I proceed to question them...

The only thing I really have mix/matched is keeping the MF9 bootloader, and I believe there are very valid reasons for doing that (if I hadn't, I would NOT BE ABLE to go back to MF9, because of Knox). So, while that might lead to an issue, it is then problematic either way.

As it stands right now, I do have the standard 4 files and folder in my carrier folder, so does this mean I SHOULD be OK now?

And what particularly confuses me is that everything was working fine (probably the most stable phone I have ever had) after I did the NAE update (keeping the MF9 bootloader method). At some point LATER this issue started, and I think it was when I messed with my APNs, and something happened that I seem unable to undo, even by Nandroiding back before this point.

What is talked about in this thread seem likely to me to be what is now causing my issue, but I an NO expert on these things, just try to make as much sense of them as I can... ;)

If you think there is a fair chance that going back to MF9 and doing a ##72786# would solve this, I would certainly be willing to do so!

Thanks for your assistance!

(EDIT: I also don't understand why it works fine for a while after booting and when it stops working, but will work again after rebooting... maybe there is a logical reason for this, but it makes no sense to me. I can't understand Logcats well enough that I have been able to spot anything there, if there is anything...)

This is, IMO, a MAJOR ASSUMPTION. requiring expensive software, that many choose to overlook...
[Sprint Samsung Galaxy S 4 General] ecs87:
Huh? Expensive? Lol. CDMA workshop is free (if you take 5 minutes to search for it) QPST is free and DFS is free. I guess free is expensive nowadays lol. Anybody flashing phones should already have ALL three of these CDMA tools.

---------- Post added at 09:56 AM ---------- Previous post was at 09:55 AM ----------

Your APNs should be stored in the system partition. This is the "ROM". Try going back to MF9 everything.
[Sprint Samsung Galaxy S 4 General] rsngfrce:
I could of course be incorrect, but while it is easy to find CDMA Workshop for free, not by legal methods. The demo version of DMS is free, but the other versions cost money as far as I can see. QPST I was not familiar with until you mentioned it here, I'll look into that.

That's pretty much what I figured... I'm headed in that direction. Thanks.

Androdevil is at work in my phone...

FREAKING HELL! After MONTHS of being unable to update my PRL or PROFILE, I decided to try it one more time before going back to MF9... and it WORKED! This is the kind of thing that doesn't make me know if I should jump for joy or scream in agony! :eek:

Now if only this SOLVES MY PROBLEM!

(UPDATE): For what it's worth, I've tried to check for anything that has been modified in my Carrier or EFS folders after the PRL and Profile update, and the only thing that I can find that has changed are the "properties.db" and "properties.db-journal" files in the Carrier folder.

The following values have changed in my properties.db file (all the others are the same):

LTE/APN/1, LTE/APN/3, LTE/APN/4, LTE/APN/5, LTE/APN/6, LTE/APN/7 were blank and were changed to "0"

sdm/session_type was "CI_PRL" and changed to "CI_DI"

sdm/app_prev_state was "SESSION_INTERRUPT" and changed to "APPLYING"

lte/service/forced was not in in my old properties.db and was added with a value of "0"

I don't know how to read the "properties.db-journal" file, so I can't tell what changed (the MD5 is different though, so I know it changed).

(SECOND UPDATE): So, does anyone want to know what I did to allow me to update my PRL and Profile? I HATE to say what I believe allowed it because it makes NO sense to me, but it is the only thing I can think of that I have done that could have had any possible affect since my last attempt to update the PRL and Profile, despite making no sense...

What I did was copy my Carrier folder and EFC folder to my external card using Solid Explorer. That is it. I did this so I could compare them to what I got after reverting to MF9 (which I ended up never doing). Please feel FREE to tell me this could not have solved this issue, I agree with you, but I can think of nothing else I have done recently that could have possibly fixed this either... so...

(THIRD AND FINAL UPDATE): Despite updating my PRL and Profile, my issue with loosing my mobile connection and GPS a while after rebooting continues, so the issue must lay elsewhere... :crying::crying::crying::crying:

Hello,

Is this working with Samsung Galaxy S4 LPH - L720T?
[Sprint Samsung Galaxy S 4 General] Ju5t3nC4s3:
No matter what carrier folder I use on my note 3 with 4.4.2 kitkatkiller rom on boost mobile. I still get a preparing network notification. All the read write property's are correct and my 3g profile is flashed correctly becose its showing EVDO REV-A. If anyone has a different carrier folder for me to try please upload for me of PM me please. This is all I have left to get my note 3 fully working on boost,besides the visual voice mail and voice mail notification.but don't know if anyone has that working properly on boost yet.

[Sprint Samsung Galaxy S 4 General] ecs87:
If you're getting a preparing network notification it means you've messed up your carrier folder or ROM. Odin the Firmware build that you're CURRENTLY on (or newer), root the phone, install es file explorer, copy the note 3 carrier files to your carrier folder. FIX PERMISSIONS (DO NOT SKIP THIS STEP). It WILL work after this if you've filled in the MDN, MIN, and profile 1. If it didnt, you did something wrong.

Is Update Profile working for you?
[Sprint Samsung Galaxy S 4 General] oc34:
Could I use this solution using S3 as a SOURCE for my S4?

Greetings everyone. My first time here.

I was googling like crazy trying to find a solution for my Galaxy S4 4.4.2.... I can't seem to be able to Update Profile/PRL. Finally I found this site and I am hoping that I will resolve the problem using this method.

I have an Galaxy S3 (possible "SOURCE" ) flashed to boost mobile and the Update Profile which already works.

Now, being that my "SOURCE" would be Galaxy S3, could I use the files from "SOURCE" for my "TARGET" (Galaxy S4)?

Lastly, sorry if this is so obvious but what are those "ATTACHED FILES" for?

Thank you a bunch.

Oc
[Sprint Samsung Galaxy S 4 General] AlpineMan:
If your target is a Sprint S4, just use the attached S4 carrier zip file found in the first post.

How can I tell the device on this situation? Recently, I try to activate a S4 Sph-l720 on freedompop for a family member and remain in-activate or profile/PRL not update able after number time of attempt. Contact freedompop and they claim they resolve the issue at their end. The device still no in-activate and can't update profile or PRL. Therefore, not mobile data connection. Do you guys thick this method may fix this issue?
[Sprint Samsung Galaxy S 4 General] vkitchai:
Update profile is failed. I upgraded Note 3 to NH7 (4.4.4) can't go back to MJ4 (4.3) using odin.

PRL remain 1 when replace carrier folder.
[Sprint Samsung Galaxy S 4 General] ecs87:
Don't flash the entire firmware. It won't let you. You can't downgrade the bootloader because it's secure. You must only downgrade the modem. Your signal and PRL will come back.
[Sprint Samsung Galaxy S 4 General] vkitchai:
Can you tell me more about downgrade the modem ? how do I do it ?

If using odin, what file do I need ?
[Sprint Samsung Galaxy S 4 General] ecs87:
I use the MI3 modem.bin file flashed through the CP slot of Odin 3.09. I rip the modem files out of the tar(ball) file using winrar. Tar files or MD5'd tar files are nothing more than Linux file archives.
[Sprint Samsung Galaxy S 4 General] vkitchai:
I got the modem.bin file from MI3 then put it on NH7, It kept repeat boot up my phone.
[Sprint Samsung Galaxy S 4 General] E-POUND:
You have to flash an older ROM other than NH7. I've read that it will boot loop which is the problem your having right now. Flash NC5 and should be good if you already have the M13 modem on there. Downgrade your ROM.
[Sprint Samsung Galaxy S 4 General] ecs87:
That's insane. Really starting to hate new updates. They're starting to mess with the modems far too much. Is the system partition the only thing preventing it from working on the MI3 modem or is it also the kernel? I've gotta see if I can replicate this. Thanks for the heads up!
[Sprint Samsung Galaxy S 4 General] vkitchai:
OK, I have my note3 working now. Thanks everyone.

1) odin 3.09 with AP downgrade to NC5, then stock recovery and wipe data (got a yellow screen).

2) odin 3.09 with CP to flash MI3 modem.bin

3) prl helper with prl version 55016

4) activate this device, update profile, update prl.

P.S. After downgrade modem to MI3, About device showed MI3 and cannot use System update to get OTA.

I tried to put back NC5 modem.bin but it's failed. so I need to reverse it back to MI3 modem.
[Sprint Samsung Galaxy S 4 General] ObviousMan:
Well, I am ready to give up on that 720T and send it back to bay. It definitely would not give me data, and PRL update failed a few times, until it seemed like it went, and asked to reboot. It must have had a message which I missed since it had reset all the carrier files completely and went into HFA loop. I can not find 720T carrier directory at all. Out of desperation I tried what is posted in OP. It cleared the HFA, but there is some other problem with that since I can not manually update ##DATA# anymore, it just FC's. If I restore the carrier directory from the copy, it goes back into HFA loop.

Couple of things I was not sure about - to manually update Profile 1 - is there an instruction somewhere? Even if I try to switch to the 2nd profile radio button and write, I get an error. So I have not tried to manually fix the Profile 1 yet.

OM
[Sprint Samsung Galaxy S 4 General] vkitchai:
you can do ##3282# to edit profile 1 from the phone
[Sprint Samsung Galaxy S 4 General] ObviousMan:
Yes, that is the same as ##DATA#, it FC's without giving me ability to edit anything.

Kitkat 4.4.2 carrier fix?

So, has anyone found a fix for L600 Sprint mega 6.3 on 4.4.2? I bought the device with the OTA update already applied so I'm some what stuck on 4.4.2.

If the carrier fix does not work on 4.4.2, is there anyway to down grade the Sprint mega 6.3?

Everything works (talk, text, 3g) after flash for my SERO.

However, I keep getting the failed to register and subsequently getting the internal error 106.
[Sprint Samsung Galaxy S 4 General] ecs87:
The carrier files in the OP don't work for the mega?
[Sprint Samsung Galaxy S 4 General] srk2040:
Maybe I missed something.

In the beginning of the thread one of the requirement is that firmware cannot be 4.4.2. As someone had tired it and the carrier file did not work.

But I did try the carrier method and it didn't work. So is there a way to downgrade the firmware to 4.2.2?
[Sprint Samsung Galaxy S 4 General] AlpineMan:
Perhaps we can ask Sprint LTE account owners of these phones on 4.4.2 to give us a copy of their /carrier files.

teamview session possible?

Hi, I've read through this thread and the main flashing thread and am still finding even some of the more seasoned veterans having difficulty so I was hoping anyone would be willing to guide me with this through a Teamview session so I don't blow this up. I have 2 SERO accounts one with HTC TP 2 and one with a slide out TP I would like to put the TP2 on a Sprint branded Note 2 and the TP on Note 3, this phone does try to activate hands free everytime I turn it on and off so I reckon it has the HFA issue.

In Need of Carrier folder for SPH-L720T

Hi there,

Hey kind people, i have spent to many precious hours if not days to get past HFA screen. I'm on sero and everything was working just fine from the start, I flashed the phone with another ESN and it activated right away, months later I decided to update to the NG5 firmware and I lost 3g. I can do Activate phone over WiFi, It texts and calls but data stats at 1x, 3g not activated, no passing for renew profile or prl. I suspect it's the carrier folder, which is unique to the tri band spark version I have. Can anyone please post their zipped carrier folder from L720t here? Thanks in advance!
[Sprint Samsung Galaxy S 4 General] AlpineMan:
Just a quick update. Looks like the Sprint LG G3 is suffering from the same issue as described in OP. The fix is exactly the same. Copy the /carrier folder from a working Sprint LG G3 to the broken one. Luckily, I have both, so I was able to test and verify that indeed that is the fix. ;) I zipped up the /carrier folder from a working G3 and unzipped to the broken one. Fixed the permissions (I have screen shots of all file/folder permissions). Voila. Fixed. This also fixes missing apps such as Sprint Zone and Wi-Fi Calling.

The LG G3 is KitKat. So I'm pretty confident that if we get updated /carrier zip files from working Samsung S4/Note 3/Mega phones running on KitKat, then the fix should work on KitKat ROM, too.

Need /carrier for SPH-L720T: Can't Update Profile, get rid of HFA on boot

Hi there,

Thanks to everyone for sharing.

I really need the /carrier folder from a working SPH-L720T on Sprint.

The story, perhaps it could help someone, is this.

I initially acquired a S4 Spark (SPH-L720T) , flashed it to a simple old EVDO Sprint donor (I am on a Sprint legacy plan) - just the MEID, and it fully activated at EVDO 3G as soon as I entered MDN and MIN. I used it for months without any issues (except no MMS)

Then I decided to update from NC6 to NG5 stock. :mad: I was rooted, OTA went with an error, and WiFi stopped working. I flashed the whole new NG5 stock, WiFi was fixed but now my phone was not getting any data and I was in for the HFA loop.

If I manually entered MDN and MIN, I would get phone/text working but no data whatsoever. Only after I replaced my/carrier with the content of the S4 carrier.zip from the 1st post, ##SCRTN# and a subsequent "Activate Phone" in settings would populate MDN and MIN and get me 1x data but no 3G. Finally I got my old donor phone's NV Items 465, 466, 1192, 1194 and wrote them to the SPH-L720T. I got 3G (EVDO v A) data immediately after reboot but HFA on boot persists, with error 106. Any time I try to Update Profile or PRL it calls for HFA.

After all the reading it looks like the key is the correct /carrier stuff for SPH-L720T. Can anyone please zip and post it? And perhaps AlipineMan could add it to the first post along with the other versions..

Another, secondary issue is that I am not getting Spark graphics and there is no Sprint Hotspot (or Zone etc) anywhere, so I can't hack it. Does anyone know how to get all the Sprint stuff back?

Thanks in advance!
[Sprint Samsung Galaxy S 4 General] AlpineMan:
You'll get all the Sprint stuff you mentioned by putting back the appropriate contents of the /carrier folder in your phone. It seems there are many things dependent on a working carrier folder.

[MENTION=3165340]japush[/MENTION] I created a new thread for the LG G3 fix. See if it will work for your L720T. However, be prepared to reflash your phone from scratch if it doesn't work. If you're brave enough and would like to give it a try, have a look at my signature for the link to that G3 thread for the download.
[Sprint Samsung Galaxy S 4 General] japush:
[MENTION=1130160]AlpineMan[/MENTION], I could not find your signature to get to the LG G3 thread.. . I can't tell you how much time I have already spent on this, so entire reflash is not a sweet idea to me, but it's curious how it's been so difficult to find the S4 Trimode/Spark /carrier. It just looks like the easiest solution, doesn't it?

In any case, if noone posts that folder, do you think the Note3 or Mega you have posted in OP might be the ones to try on my triode? S4

you ve posted worked for me to get it actually activated from ##SCRTN# albeit only at 1x and with HFA loop going. As I said I got 3g /evdo a by writing the 4 donor's NV items., but HFA is still there. Pretty weird.

LG G3 thread: http://xdaforums.com/showthread.php?t=3011071

Someone's gotta have a good working L720T /carrier folder. Those with LTE accounts sure do! Maybe go to the Sprint S4 General Discussion section and make a request. The user just needs to be rooted and have root enabled ES File Explorer (or similar) in order to copy the folder. And yes, you can try the other phone's carrier folder to see if it will work, but again... No guarantee. Not sure if it will wipe your flash either.

I have a mega sph-l600 to boost it is kiking my butt Im not a newbie to this but feel like one for sure.

I have flashed it in DFS all goes fine there except after it is flashed it will not let me go back into it in DFS to read the data that was flashed it wont unlock the device with either the msl or samsung password only way back in is ##786# and rewrite it again

3g data does now work so something went right

I extracted the carrier from the OP for mega to the carrier folder and checked and double checked the permissions they are right

When I click on update profile or update PRL it says initializing app and thats as far as it goes

Outbound calls do not work (the number or code you have dialed is invalid)

[Sprint Samsung Galaxy S 4 General] kali323:
Just to let you know guys that im a boost mobile dealer and they let us rescue sprint phones to boost. So i can make the galaxy S1-S4, Note 3 and LG G2 to boost with 4G LTE without flashing it. Theyre always adding new phones so the S5 will be possible soon and hopefully other flagships. But the phone must be clean imei and you need the sprint sim card. You dont have flash anything, everything works including mms and 4G. And best of all you dont have to worry about it stop working out of nowhere especially when you want to update and/or factory reset.
