gingerbread att tab

Just flashed the new gingerbread rom. Works great but it doenst recognize my sim card or network. I have att tab. Any help to restore it?

Did you remember to download the Modem package too? That's what I'm guessing.
sent from my Galaxy Tab using Cerebral up-link

Did you flash the version with the bootloader? Any whiteline issue on boot?

No I didn't download or flash a modem do I need to? I flashed the one with the bootloader. No whiteline I noticed.

I flashed with bootloader, tried 2 different modems, and no network. wifi works. tried flashing back to stock and everything went crazy. While I was using Odin, I STUPIDLY, plugged in my Captivate to charge without thinking, causing Odin to fail and I got the "phone - ! - PC" Icon.......talked about scared! Ended up using Roto's ATT stock image and Odin to get it back running again,barely. Now I get CRAZY lines when I boot (like if you tweaked the cable to an LCD screen), can't see Recovery screen....total craziness. Still no data. so I flashed back to OverCome Gingerbread ROM following his instructions, still no data
UNTIL
I swapped the SIM card with my phone. I suddenly got data on my Tab, but data would not function on my phone. Seems like the problem follows my SIM. Background: I also had a weird issue before hand where I couldn't open the Market on Cellular data without killing the data connection on Stock Rooted.
Thought I'd share.
EDIT: oh, and I can send text messages without issue.

Go to Settings, Wireless & Network, Mobile Networks, Access Point names and make sure you have one called Broadband (assuming you are on the ATT monthly data only plan)
If you dont, create a new APN and name it Broadband & make the APN Broadband as well. Just leave the other options and save it & select it.
I think by default it comes up with the ATT wap.cingular APN with doesnt work with the Tab Data plan.

Well Son of B....you rock. What pisses me off is I've screwed up my boot screen (all kinds of colored lines) trying to fix this. Thanks.

Gingerbread 2.3.3 installed modem does not work
AT&T monthly pay as you go. What modem.bin do I load? Where can I get it. Is there any additional setup instructions?

Follow my instructions above and flash the JK3 modem fromt this thread.
http://forum.xda-developers.com/showthread.php?t=1069727

Mine keeps saying insert sim card to access. So how do I get it to recognize the sim?

Please anyone with some help? Can I store back to original att froyo and just wait for official upgrade?

Have you guys entered in your APN settings for ATT Broadband?
I am also having a strange radio issue. I am using an ATT Tab with Overcome v2.0 Beta 2 and the JK3 modem. 3G data works great until I try to access the Google Android Market. As soon as I do it drops the 3G connection and wont come back until I reboot it. If I dont go to the market or only go to the market on WiFi it works just fine. I also verified that the same behavior happens with the JPZ modem..
My theory is somehow ATT is blocking Gingerbread Tabs from going to the market using their SIM card. Therefore I think maybe I need to edit my build.prop to spoof them. Can anyone recommend which values should be changed? Can anyone think of anything else that could cause this? Can anyone reproduce this issue on their ATT tab?

You used the bootloader patch app, right?
Reinstall the stock 2.3, then the root, then overcome. Follow the overcome guide, this time put the modem.bin in the phone slot in odin. There is no other fox for the wiggly lines. If you don't reflash everything, you can't get into recovery mode.

i cant get into the network settings as it tells me to insert a sim. I tried to flash the modem as well with no luck.

ok so I turned on my tab to play with it a bit and I had data! It was an H and seemed to work. When I restarted the tab it stopped working and said no sim again.

1) The Gingerbread rom has a modem with it that works fine on AT&T.
2) Did you leave your sim card in while flashing?

i did leave my sim in while flashing. Should I have it out? It seems the tab only recognizes the sim card every so often. Not all the time. Any way to flash the sim recognition part?

Could you please post how you flashed your att tab so I can follow it? Thanks.

your links dont work.

I am on ATT and did not have a single issue on this rom with 3G or any other APN related issues.
I didn't even have to detect network to get it to run.

Same with me after running Nav's Mod file. I will try this and reset settings later to see if it fixes my internet issues.

Seriously? Do you have to post a tutorial for this? Are you that desperate for a thanks? Look around there are at least 3 threads with this same info.

Some people need more hand-holding than others. Making it idiotproof has a niche.

i have flashed this mulitple time. fresh. unlocked. rooted. everything. i cant get it to work on my phone, i get a signal and the one bar thing but no data. its fkn gay/weird. i only get this with 2.3.4. anyone know what i am doing wrong or can help me? i woulkd really appreciate it.

Settings for internet if on 3 Network
Ok at first when i go my phone i couldn't make a calls, and when i did the phone would restart itself. So i flashed the radio to 87.00r and it worked.
Then i had to manually set up the apn in order for my internet to work (Mobile Data)
Menu, Settings, Wireless & Networks,Mobile Networks, Access Point Names, create or edit apn.
Name - 3
APN - three.co.uk
ANP TYPE - default
save settings and restart your phone - and that's it really.

I downloaded APN Manager as you stated. I'm in Minnesota, and I switched the APN to one for T-Mobile and got double the speed. Why is that?

How did u flash 2.3.4 and U have your APN set up right and select HSPA and restart. U can check if trying to connect, Go to Settings, to About phone, to Status And Its under Mobile network state!

FOR THOSE ON AT&T
If you are on the AT&T Network and you upgraded to GB from Froyo and didn't delete your APNs or carried them over using Titanium Backup, you should be fine.
For those of you who didn't or installed Navalynt's Mod/reset your data/whatever else you did to lose your APNs, you don't need to download APN Manager in order to get it back.
It seems the problem with the defaulted APN for AT&T in this particular build is that it is missing the password. If you put back in the password, it works perfectly fine. The password is 'CINGULAR1'. So for anyone having problems with their APNs, try defaulting it or just adding the password in first.
Let me know how that goes for you guys
P.S. Can we get someone to mod the default APN to include the password? Or even better, to replace the defaults and add in the defaults from Froyo build? If someone can (or i can try to look into it) that'd be amazing

[i537]New Easier Sim Unlock Method 4.4.2/5.0.1

Sim Unlock Method 4.4.2/5.0.1
Disclaimer: i AM not resposile for anything that happens to your phone in the unlikely event something does happen.
this has only been tested lightly but it should work all-right. this is for the i537 S4A only.
You Need to start out on either NE3 or NH3. Downgrade now if you need to. Just remember when downgrading don't flash bootloader. This needs Odin and root to succede. Now That thats out of the way you need to download some files to deal with later on.
MF1 Odin flashable
regionlockaway go to the second post and download the apk to install on your phone.
this method uses an old method in a new way.
here is the guide
1. install regionlockaway and reboot to download mode
2. Flash modem.bin with odin in download mode
3.reboot to system and use regionlockaway. follow the instructions in the app.
4. profit?
As far as my understanding after you do this you can update your modem without it reverting back to being locked. I am running oc7 modem on a T-Mobile MVNO without issues( if you want aws unlock you are going to have to use this then the appropriate modem for that and not allow for the modem to update when updating to oc7 by modifying the oc7 installer and removing the modem from it)

I am ready... I have been reading for days about sim unlocking on 4.4 and up..I finally coined up $25 for a code but takes up to 5 days, 2 days ago. my next attempts were going to be with my paid copy of CDMA WS. Either way it is just to experiment with and would love to gain the knowledge. I have a couple different carrier sims ready to go. I would love to give it a shot.....
mateo121212 said:
hey guys i have created an easy sim unlock that should work for 4.4.2 and for 5.0.1
for the 5.0.1 sim unlock you have to do it on 4.4.2 and flash a modified partitions file to upgrade to 5.0.1 while keeping sim unlock.
if you guys are interested in it let me know and i will set up a few beta testers for it. i cant say for certain that it works because i dont have a non ATT sim card to test it with.but it should work. it should also allow you to enable aws for those on T-Mobile by following a secondary guide.
let me know and i will start having people beta test. i only need between 1 and 5 testers

ok ill pm you with a guide once i have it written up.
EDIT: it should be in your inbox

i was able to test a verizon lte sim and it didnt give me any issues. it regestered the number in the status. so i belive it worked. i would like some more testers to get information about it. i need more testers before i feel ok giving out the method.

Been sooo busy!!!! K, thank you for the guide. I haven't been able to try anything except a Verizon Lte sim. It registers the number and the network lock is gone. However I don't believe we will get data service with a Verizon sim as I don't believe the hardware is capable?...I wasnt able to place a call as I got" Emergency calls only", all I did was swap sims, occasionally I have to call Verizon and have them add the new phone to the plan before it will work and I didn't do that yet. Will try a different carrier sim tonight.

so before you did the guide did it give you issues with the verizon sim? and now it dosent?

It did give me issues before flashing the mf1 and after the flash and region away no nagging about sim unlock code! Havent gone any further yet. I will report back after using a different carrier sim besides verizon that is.....I think it works....

sweet thank you for the feedback man. i did the 5.0.1 upgrade method i detailed in the PM after i finished doing the unlock on my phone and it worked the same as what you described (i only had access to vzw lte sim also) so i belive i made the update file correctly also. im not really getting any bites on more testers so if it pans out well for you i will polish up my guide and post it here to have people test it instead of making them PM me.
thanks again for being my beta tester. if we get this working well we can save alot of people alot of money
ps for voice and sms verizon lte sims are useless because they still use CDMA for those features

Finally put in another sim...Put in a Tomb sim and no nagging about unlock code, I got "Sim not provisioned" as it isn't active at the moment. So I'm thinking it worked. Thank you. I was thinking I'd get voice and edge speeds with a Verizon sim in this phone, (utilizing GSM bands), in my area anyway, but maybe I'm mistaken. I'll post again after using another carrier's sim.....

I did as instructed and according to flashfire at the end of flashing, it said it was successful and it rebooted (so far) to the lollipop boot animation and am awaiting for it to get past the at&t logo screen. Its at least gotten a lot further than all my earlier attempts...I am assuming its taking a little while for its initial setup of OC6....
more later on its success or failure....
well it was a partial success....it flash and booted into OC6 but sim card is not recognized, no baseband.....now installing updated version of flashfire....should i now flash the MF1 modem again via flashfire?
well i went ahead and did just that flashed the mf1 modem via flashfire and all is up and running successfully (FINALLY!!) with root on deodexed rom OC6...

flash mf1 modem with flash fire
make sure you are rooted and have busybox
use region lock away. try with att sim in phone.

Trying to do this for my s4a but flashfire is being uncooperative, it just crashes any chance it gets. Any other flash apps this will work with?
Edit: do I need safestrap for FlashFire?
Edit2: Fixed the issue with flashfire, If anyone runs into this issue you need to flash stock NE3, and re-root.
Rest of tutorial went perfectly. Cannot test unlock status atm, but no errors.
Thanks Matteo, you're a top lad.

Will this same method work with a deodexed OC7 ROM? I only ask because of the I537_OC6_Stock_Partitions_mod_sim.zip - not sure if this still works the same for OC7. Just to clarify, do you know if region lockaway is necessary to get T-Mobile AWS/HSPA bands? I've got a working cell and LTE connection without doing any of this, so I really only needed to do what's necessary to get those bands (which I think the old modem will help enable).
Thanks for the assistance!

also check out this post if you have issues with getting qpst to work. dont follow the whole post just qpst part http://forum.xda-developers.com/showpost.php?p=56023258&postcount=68
then follow the guide i posted in my last edit to keep the aws unlocked modem while on 0C7
edit:
you can use the oc7 deodexed rom. you just have to remove the modem from the rom file useing winrar or 7zip. also you have to remove it from the updater script useing a text editor. drag it out of winrar edit it and then drag it back into winrar. that way if you flash in this order you will be fine
partitions mod file
oc7 deodexed rom.
that way you keep the modem
from when you installed and unlocked mf1 modem on 4.4.2

[INFO][HOW TO] Sprint Galaxy S4 Sim Unlock (SPH-L720/jfltespr) ATT/TMOBILE

There seems to be some confusion on the matter here in the forums.
Can I sim unlock my Sprint Galaxy S4 to use ATT/TMobile sims?
Yes
Can I do it using a Lollipop Rom?
Yes
Can I do it once I flash a KNOX bootloader?
Yes
Can I do it on OD2?
I don't think so, but maybe... The best bet is to use NG2 and then experiment from there...
Can I do it without reading/paying attention/following directions?
No.. but if you made it here, you're doing OK so far...
First off, there are 2 kinds of SIM unlock for the SPH-L720. International unlock, and domestic unlock. We will cover both.
To unlock for international carriers SIMs, you have a couple of options.
a. Have sprint unlock it for you
b. Do it yourself.
I prefer b, almost always.
Lets start off with what you'll need:
Drivers for the phone, I'm too lazy to find those, but if you can't, you are way out of your depth here.
SSU.apk from here.
An NG2 Stock Rom (modem and ROM) here is an Odin tar that i used when I did it.
Odin from the same post that tar came from... (here)
TWRP recovery in tar format from here (i used 2.8.4.0, but I don't think that matters)
adb ( i use this minimal adb installer but any adb install will work.)
THIS WILL PROBABLY WIPE ALL YOUR DATA.
Put your phone in Download mode (Power + Vol Down)
Open Odin
Click the PDA button, choose the tar.md5 file you're flashing. (the stock ROM from earlier)
Uncheck Auto Reboot
Plug in a decent USB cable, from the phone to the PC
Hit start
It will take a few minutes, no worries unless you get an error.
When it is done, Hold Power + Vol Down until the phone reboots into download mode again
Click PDA in Odin and load the TWRP tar you downloaded earlier.
Hit start. This will take significantly less time.
When it is finished, Hold Power + Vol Up to reboot into recovery.
When TWRP is fully loaded, click reboot then reboot system.
It will tell you that the ROM is not rooted, and ask if you want to do that. (if you used the tar from above) and of course we want to, so let it.
Let the phone fully boot up.
Goto Settings, More, About Phone.
Find the line that says Build Number, click that line a bunch of times until it says "You are now a developer".
Now hit back, and goto Developer Settings.
Find Debugging mode and enable it.
Using adb
Code:
adb devices
that will respond with whether it finds your device or not.
Code:
adb install /path/to/SSU.apk
that will install SSU.apk from earlier..
You'll want to have the screen of your phone on for this part because you will need to approve your PC to connect.
Goto your app drawer, and run SSU
Click the Unlock button
Now your phone is SIM unlocked for international carriers... But what if you want domestic carriers too?
Unlocking for Domestic Carriers
First things first, you have to do the International Unlock explained above (you didnt think you were gonna get out of that did you?)
After that, load ADB back up
Code:
adb shell
Code:
su
am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://27663368378
That will pop up a menu on your phone
Click (UMTS) then (DEBUG SCREEN) then (PHONE CONTROL) then (NETWORK CONTROL) then (GCF) then the top option.
Now reboot.
You are now unlocked Internationally and Domestically. Goto your mobile network settings and put your apn settings in (if they arent already there off the sim) and you should have data too.
From here you have a couple of choices.
a. Stay on NG2
b. Goto another ROM (i usually just flash CM at this point, YMMV)
c. experiment yourself and try to use OD2 (I've heard flashing the OD2 modem relocks it, didnt try because I didn't want OD2)
If you stay on NG2 then I suggest this apk to Stop the Sprint Hands Free Activation from nagging the **** out of you..
NOTE: as of tonight, any CM12.1 nightly after 6/23 causes a No Sim card error. This has nothing to do with the unlock, its just messed up, so until its fixed use the 6/23 nightly.
Hopefully that answers some of the questions I keep getting in PMs and what not.. If you have any question, feel free to ask.
I might not answer them, because I rarely frequent the forums anymore, but lots of people here can probably answer the questions you have.

And anyone else I forgot (I'm sure I did)

I would probably recommend removing all references to rooting since it's not necessary. Some may only want to unlock, not root.
Substitute the dialer code for the terminal command when it comes to launching the service menu.
And putting the apk on the phone's storage and installing it with a file explorer is probably easier than adb install, for most people.

I just documented what I did. there is no one way to do it. you are more than welcome to document them in your post if you want.

I'm going to try this today and will report back. I switched to tmobile and got the s6 edge and since my sprint contract was up I was able to keep my device. Now I want to get it to my mom who has a beat down metro pcs device. In theory since metro is tmobile it should work right?

If metropcs uses sim cards, and the Bands that the GS4 has, then yes it should work. You'll obviously need APN settings for data.

So this method you need to be on KitKat in order for Suu to work. I also can't get a hold of galaxytools as the developer wants you to buy it now.
Also any ideas how to do the domestic unlock without adb?
Sent from my SPH-L720 using Tapatalk

I don't use galaxy tools, and if you aren't on kit Kat yet, you can revert the modem and use the original unlock posted by autoprime.. Or you could just flash the rom I linked too, which is lollipop, not the newest but works fine.

And as far as adb, you can just use a terminal app.. Except for installing ssu.apk, but you could just push that to your phone and install it with a file manager

I followed the above steps and still can't get it to work. Im back on kitkat and unlocked the sim. Did the terminal command and followed those steps. rebooted and under About Phone> Status it still says sprint and shows my old phone number that was tied to my sprint account. Am i missing something? I went to settings and changed to gsm/utms and tried that but nothing.

Did you put a sim card in?

Yes it was a metro pcs sim. I spent a couple hours tinkering with different steps from older threads and still could not figure it out.

Metro is unique in that you can't switch phones just by popping a SIM in.
You have to contact them and have them register the new IMEI to the phone number

There seems to be some confusion on the matter here in the forums.
Can I sim unlock my Sprint Galaxy S4 to use ATT/TMobile sims?
Yes
Can I do it using a Lollipop Rom?
Yes
Can I do it once I flash a KNOX bootloader?
Yes
Can I do it on OD2?
I don't think so, but maybe... The best bet is to use NG2 and then experiment from there...
Can I do it without reading/paying attention/following directions?
No.. but if you made it here, you're doing OK so far...
First off, there are 2 kinds of SIM unlock for the SPH-L720. International unlock, and domestic unlock. We will cover both.
To unlock for international carriers SIMs, you have a couple of options.
a. Have sprint unlock it for you
b. Do it yourself.
I prefer b, almost always.
Lets start off with what you'll need:
Drivers for the phone, I'm too lazy to find those, but if you can't, you are way out of your depth here.
SSU.apk from here.
An NG2 Stock Rom (modem and ROM) here is an Odin tar that i used when I did it.
Odin from the same post that tar came from... (here)
TWRP recovery in tar format from here (i used 2.8.4.0, but I don't think that matters)
adb ( i use this minimal adb installer but any adb install will work.)
THIS WILL PROBABLY WIPE ALL YOUR DATA.
Put your phone in Download mode (Power + Vol Down)
Open Odin
Click the PDA button, choose the tar.md5 file you're flashing. (the stock ROM from earlier)
Uncheck Auto Reboot
Plug in a decent USB cable, from the phone to the PC
Hit start
It will take a few minutes, no worries unless you get an error.
When it is done, Hold Power + Vol Down until the phone reboots into download mode again
Click PDA in Odin and load the TWRP tar you downloaded earlier.
Hit start. This will take significantly less time.
When it is finished, Hold Power + Vol Up to reboot into recovery.
When TWRP is fully loaded, click reboot then reboot system.
It will tell you that the ROM is not rooted, and ask if you want to do that. (if you used the tar from above) and of course we want to, so let it.
Let the phone fully boot up.
Goto Settings, More, About Phone.
Find the line that says Build Number, click that line a bunch of times until it says "You are now a developer".
Now hit back, and goto Developer Settings.
Find Debugging mode and enable it.
Using adb
Code:
adb devices
that will respond with whether it finds your device or not.
Code:
adb install /path/to/SSU.apk
that will install SSU.apk from earlier..
You'll want to have the screen of your phone on for this part because you will need to approve your PC to connect.
Goto your app drawer, and run SSU
Click the Unlock button
Now your phone is SIM unlocked for international carriers... But what if you want domestic carriers too?
Unlocking for Domestic Carriers
First things first, you have to do the International Unlock explained above (you didnt think you were gonna get out of that did you?)
After that, load ADB back up
Code:
adb shell
Code:
su
am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://27663368378
That will pop up a menu on your phone
Click (UMTS) then (DEBUG SCREEN) then (PHONE CONTROL) then (NETWORK CONTROL) then (GCF) then the top option.
Now reboot.
You are now unlocked Internationally and Domestically. Goto your mobile network settings and put your apn settings in (if they arent already there off the sim) and you should have data too.
From here you have a couple of choices.
a. Stay on NG2
b. Goto another ROM (i usually just flash CM at this point, YMMV)
c. experiment yourself and try to use OD2 (I've heard flashing the OD2 modem relocks it, didnt try because I didn't want OD2)
If you stay on NG2 then I suggest this apk to Stop the Sprint Hands Free Activation from nagging the **** out of you..
NOTE: as of tonight, any CM12.1 nightly after 6/23 causes a No Sim card error. This has nothing to do with the unlock, its just messed up, so until its fixed use the 6/23 nightly.
Hopefully that answers some of the questions I keep getting in PMs and what not.. If you have any question, feel free to ask.

How are Data speeds?
This is great thank you for posting this detailed one. If i can't figure out how to get my phone working right I'll flash stock firmware and start OP's process. Can you tell me what data speeds are you getting? I've got mine unlocked and working by changing my modem and using s4 flasher among changing other settings. It's a Sprint S4 L720 going to Tmobile. I'm only getting Edge speeds of .08 mbps and the voice is sometimes garbled. I'm not sure how I can get it unlocked and working well with everything working and getting the HSPA+ speeds. I live in a 4gLTE area so I should get at least 3g speed according to tmobile's coverage map using 72703 zip code. Trying to figure this out if anyone has suggestions on how to get out of EDGE speeds, the 2G EDGE capabilities are appalling. I haven't flashed any custom ROMS btw.

I only used it on att, but if your speeds are low then TMobile in your area probably operates on a frequency the s4 doesn't use.. Or your apn is wrong, idk which.

1. Make sure modem version matches software version
2. Make sure network mode is set to WCMDA preferred or GSM/UMTS.
3. Check Settings->About phone->Network to make sure you're actually on EDGE.
You could live in an area that T-Mo hasn't refarmed to 1900 yet. If that's the case, they're running HSPA on 1700 there, and the phone doesn't have that frequency. So that would explain only being able to get EDGE

[NOVUS][INFO][JFLTESPR][Sprint/Boost Mobile APN-FLASH *SPARK*]

I spent the last few days on my phone learning all about flashing Cyanogenmod, the differences between SPH-L720/SPH-L720T and wanted to put everything I learned about my experience in one thread as it is pulled from countless sites.
I have the Boost Mobile Galaxy S4 SPH-L720T, rooted, flashed CM13(unofficial) with LTE Triband aka "Spark" working, confirmed.
Here is what I know:
1) Sprint Mobile and Boost Mobile are all on the same frequency's.
2) jfltespr Rom for the SPH-L720 also works on SPH-L720T. It's only a Rom, zero difference between the "T" version and regular in terms of the OS, the "T" is hardware.
3) The difference between SPH-L720 and SPH-L720T hardware wise is that the SPH-L720T can receive multiple channels for downloading on the LTE network and the SPH-L720 can only do one, This is the "Enhanced LTE" or "Spark" you hear about.
4) For Boost Mobile, Installing the jfltespr Sprint build for the SPH-L720 or SPH-L720T will not work out of the box. You need to flash the Universal_Boost_APN_Fix-R2.2.zip. After loading in the CM Zip, zip this as well. If you forget, no biggie go back and do it after. This will fix your APN's, label your carrier correctly, which in turn allow you to use LTE, MMS, Triband aka "Spark" (You will not see the spark spiny thing, but it will work, keep reading). Also, side note you may need to wait and/or restart your phone a few times after you are set up with CM. Basically your phone needs to send info to the carrier tower and it all needs to sync up. Mine was fully working in under 20 mins. It's like when you activate a phone for the first time is all.
5) To verify the Triband or "Spark" is working download LTE Discovery App. The Triband or "Spark" Network runs on 800mhz Band 26 for voice, 1900mhz Band: 25 for Up/Down Data, and 2500mhz Band 41 for Down Data but at a higher DL rate. See these articles for more details, Sprint Network Explained, Frequency Faq's

UPDATE: I changed a setting in the MMS, turns out Boost Mobile requires a Username for mobile data to work correctly. This is now Ver. 2.2.

Hi there. What do you mean by "zip this as well"? Do you mean upon fresh installing CM we should also add the "Universal Boost APN" zip at the same time (in TWRP for example)?
I am guessing my issue is totally different, but thought I would ask anyways. I have a Samsung S4 on RingPlus (not Boost, but still an MNVO on Sprint). I have CM12 installed. everything works great except MMS. I can send normal text but cannot send (or receive) photos/multimedia. It complains about APN settings. I have a fresh CM installed so I'm willing to try anything to trial and error this thing.
Thanks for any ideas.

You can flash at the time you install the rom to save the APNs as default, or you can zip any time. However, if you flash after the install your default will be whatever CM's where.
This zip may not fully work for you then, but I did do some googling for you and found this below, if those apn settings work, let me know and I'll try to make a zip for you for future roms and quick flashing

@ThomasJoseph315 Every time I flash this zip it says error 7 and will not flash is there a way to get this to work for me I have texts and calls but zero data and I need it for navigation. I am running official jfltespr cm13 on my boost Galaxy S4 thanks in advance.

Did you clear the data, cache and delvik cache first? The only reason I ask is because I made that mistake trying to "test a flash" before I lost all my stuff. Remember, you'll only have the space for the micro Gapps without re-partitioning.
Also, the Boost APN fix didn't work for me, nor the other 9 or so that I tried. Then I came across an old thread where I made a fix for the APN on my old Cyanogenmod setup with my L720 piggybacked off the work of mopedryder. , and I'll be damned. Still works even on my replacement L720T.

Not sure why, but this isn't working with the "Official" build.... Looking into this..

Yea, I was having a bear of a time with the MMS and APN stuff. It looks like they pushed some changes that messed with the "Boost APN fix R2 and also my old fix. What I found works now was hand editing the apns-conf.xml file to just the basics. Nothing but a boost apn and a very cdma apns just in case. Flash rom, flash gapps. After it booted, I copied that in to the /system/etc folder over the old one with file explorer, fixed permissions to match the old file and boom... MMS and LTE after reboot. You can give it a try if you want. Just unzip and copy/paste where I said. Let me know what you get if you try it. Also, let me know if you can edit APN settings while on wifi with this. Just curious. If it works, we can throw it in a flashable zip to flash after gapps.

MMS and LTE working!
I used the flash link provided in this thread Universal_Boost_APN_Fix-R2-2.zip This got me LTE, but still no MMS.
I followed the instructions in the last post, but they didn't work. I kept trying, and had no luck...this was before trying the flash file above.
After getting LTE, I decided to see what I could find inside of the apns-conf file. I checked out the settings and then did some searches for APN settings and found that the line for APN type was potentially misconfigured, so I edited it manually in the apns-conf file, because I REALLY didn't want to flash my phone for the umpteenth time. I also changed the bearer number to "0"
The previous type was: "default,supl,mms,dun,fota"
The type I found through apn.gishan.net was: "default,admin,fota,mms,supl,hipri"
Once I changed that in both lines that the type appeared in and changed the bearer numbers to "0" my MMS started working, as well.
Hope this helps someone out there so they don't have to search as long as I did.
Sprint Samsung Galaxy s4 moved to Boost Mobile
Icky Samsung system, I will not miss you.

Hi everyone, kinda new to the S4 forums. (not Android dev) my current daily driver is a SPARK on boost (running cm13) and my wife has the L720 also on boost. So given that I have the rare opportunity to dig into both activated devices and collect all the radio/modem/APN data from them in order to help this thread and maybe actually contribute something instead of just lurking and reading
So after about 3 weeks of digging and testing and comparing, also trying the edits suggested above on what works for them I have found the proper network settings in the apn-conf.xml. my attempt was to get them as close to the stock ok3 apns as possible and they are very close. MMS works great, LTE shows up right after boot. I also found that after flashing Unerversal_Boost_APN_fix.zip, sometimes mobile data (LTE) would not come back after WiFi was on and then disconnected like when l left the house for work. Toggling airplane mode did no good. Only a reboot would get LTE back. That problem seems to be solved too.
I also took apart the Universal_Boost_APN_fix.zip provided in the op, studied and compared it to stock files and my ok3 modem logs.
In the fixprop.sh, the
sed -i 's/ro.telephony.default_network=.*$/ro.telephony.default_network=8/' /system/build.prop
Command sets the build.prop ro.telephony.default_network to =8
But in both L720 and SPARK, stock boost ok3 the network is =10 so I edited that.
Also I found that
sed -i 's/gsm.operator.numeric.*$/gsm.operator.numeric=311870/' /system/build.prop
Makes the build.prop call for the apns with the numeric tag =311870. but in the apn_conf.xml the apn numeric tag was = 310120 so I just changed the apn to =311870 so now the build.prop will set the right apns on boot.
Something else I found when reading modem logs from both the L720 and the spark is that in the spark, the modem actually calls for
ro.product.name=jflterefreshspr and ro.build.product=jflterefreshspr from the build.prop
I never could find out why it would need that ( and I tried) but my deductive reasoning tells me that it must have to do with initiating tri-band traffic somehow on the network. It only happens on boot but never after that. The L720 ok3 modem does not call for a name from the build.prop at all. So I added commands to the fixprop.sh to change some of the values to the =jflterefreshspr SPARK name and =L720T in the build.prop as well.
Of course, that makes the install.zip proprietary and not unerversal anymore and L720 users would need there own version so here's what I have guys.
All credits go to the original creators of these scripts. All I did was make a few changes.
Flash cm13, gapps(or not), then the APN.zip and reboot.
Note: You might notice after a reboot that the carrier will display as "sprint" but toggling airplane mode then displays "boost mobile" don't worry, it's just a display issue. network and mobile data work with no issues. I think it's something in cm13. started happening around 07/09 nightly
Sorry for the long drawn out post!! :silly:
Links removed... Updated links below

Will this work with other ROMs as well, or only CM?
I want to flash Wicked X, but I'm on boost.

The apn.zips should work on any AOSP ROM.
Not for TouchWiz ROMs
You don't need it for WickedX.
WickedX will install BoostID and set your apn settings right after it boots the first time just like stock boost ROM. After all, it is just the stock Samsung firmware with a bunch of mods added to it.
AOSP(CyanogenMod) is NOT Samsung firmware. It is compiled completely from a different source which is why the .zips are needed

If you're running CM13 stock, CM doesn't use muppets, with my build I did, so might be tempted to do a build soon, might not, truth be told I kinda gave up because of how much of a pain in the ass CDMA and MVNO's are becoming.
