Sprint Samsung Galaxy S4-Mobile Data Issue

Hello everyone,

I'm new at the forum and also a newbie an Android, so this one will make you guys laugh and wanna cry , I promise :)

I have purchased a Sprint Samsung Galaxy S4 (found out later that it is called SPH-L720) while I was in the USA through amazon.com (I'm actually from Istanbul, Turkey) and got back home. I thought I've bought an sim-unlocked version, only to find out later that it is Sprint-locked :(

I've tried many methods to unlock it, also visited "specialists" to have it done but didn't get lucky. Last weekend while I was surfing the web, I found some videos on youtube and decided to try the methods shown on the videos. I managed both to unlock and root the phone, yeayyyy :)

But doing so, I seem to have lost the mobile data connection. I cannot find the mobile data symbol on the device and no roaming is possible after I went ahead with the unlock method. Just to summarize, I had to downgrade my phone's baseband from MF9 to MDC, and afterwards I can no longer use the roaming/mobile data on my Samsung Galaxy S4.

Being a newbie, I don't want to mess my phone up any further and I would require and greatly APPRECIATE any kind of help that will get me out of my misery :) I have no clue about how to proceed, what to download, so I would appreciate if the helping party would think of me as an idiot and provide step-by-step and very open directions :)

Looking forward to any help and guidance, thank you in advance for your help.

Cihan

If your already on the new boot loader then make sure that your flashing the 4.3 tar file
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] cruise350:
You can't downgrade the bootloader, but you can downgrade just the modem to accomplish the unlock. Look for the firmware thread in the development section and find the one that has MDC modem only.

You are probably on the MK2 bootloader and, once there, you CANNOT go back beyond MJA.

Grab the MK2 .tar and Odin that.

How are you trying to load the new(older actually) modem?

It sounds like you're booting to stock recovery.

Have you installed a custom recovery - TWRP or CWM/Philz?

Modems AND recoveries can be flashed by booting to 'Download Mode' (not recovery) and then flashing via PC Odin.

I do get that you're new, and that's Okay. But spend some time reading, searching and reading and you will really find all your answers.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bleachpedro3:
I agree that it seems I'm using stock as it won't let me boot into recovery when it gives me that message but the message has appeared both in TWRP and CWM. Even flashing the recover+modem in Odin together doesn't help me. I'm using a "Modem Only" file from Unknown Force

Hey All :)

right i have just ordered this sprint s4 Blue ;) from ebay for personal usage internationally

Suppose i get the phone on stock 4.3 , can anyone outline the exact process of how i can get this one to work on international GSM networks.

My fault that i didnt ask the android version from the seller.

with what i have learned : this is how this can work

1.. run knox removal script, i mean remove knox files ( as the phone will be used internationally i am not worried about the warranty)

2.. root the stock

3.. downgrade the modem to MDC ( this i have in a form of one click odin tar )

4.. run the unlock tool and thats it ( that also i have from autoprime)

but i am not able to find the required files which will work on the 4.3

Lock screen absolute path to image file?

Sprint GS4.....

I would just like to know how I could get the location of the file for where my lock screen image is. that or id love a way (without knowing the location of the image file I guess) to make the homescreen the same as the lock screen. I've been having trouble ever since I did a couple back ups on Titanium Backup....Basically my lock screen is the image I want, and I need a way of making my homescreen back to being that image as well. I do not know the location of the image file for the lock screen as I made the background(s) quite some time ago. :\

Thoughts? Anything is much appreciated. Thank you.

I might be wrong, but if I understand, you want the same wallpaper??

If so, go to your home screen and long press in an open area, it will give you an option to set wallpaper, then it will ask for home, lock, or both screens...select both then find your image and select/ set

Edit: location? unless you moved it, select wallpapers, or gallery to search for your image... if that does not work, go on your pc, connect to S4 and search for your image
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] eyekantbeme:
That's the issue. I don't know the location of the file. I do not recall where it is. I have looked long and hard throughout my images downloads screenshots etc. I have found nothing that is that image. Now If I could take a screen shot while it's on the lock screen without the damn clock widget there, I would do that, but I have not figured out how to get rid of the clock widget. I got rid of the personal message, but the clock widget does not want to disappear. Which means taking a screenshot will have the damn clock in it and therefor make my attempt futile.

So please, I feel the best thing to ask for would be how to access the image file that the lock screen is referencing to, that is the exact same file I want the home screen to be referencing to, if so, how can I make it do that without looking up the physical image in my files.

:\ Again. Thanks.

You cant do that from the lock screen since the phone is locked you have no control over the clock or anything -.-

update prl with rooted phone?

I have s4 on MJA rooted with no knox bootloader and hotspot mod. What is was wondering is when I hit prl update and it says it checked, did it really or did the rooting and customizing turn this off but the phone still appears to go through the motions. Does ##72786# act as a re-provisioning reset and will it work while rooted or does it screw up what i have working. I have looked for information but not seeing any clear answer on this. Is there a way to manually add the prl. thank you

Need help unrooting my phone

hi i am really new to so i don't know how this works. A few months ago i rooted my phone and i havent had any problems with it until now. sprint just released it software update for the s4 (kit Kat) and my phone was unable to get it and i think its because it is rooted. so i went to techno buffalo and tried to follow their instructions exactly and nothing happened to my phone. i would be very grateful if someone can guide me through unrooted my phone safely. and if you can successfully assist me in unrooting my phone i would not mind donating to your cause.

ps i dont know how to keep responding to you so if you can send me a private message that would help a lot.

Your best bet would be to use Odin and just flash the stock mk2.tar file.

Also if you just rooted and didn't install a custom recovery or anything else and you are completely stock then just open the supersu app and do a full unroot.

As you can probably tell from my signature, I am jumping from HTC into this device. I just got one with Spark (thankfully), but I need to learn the lingo. What is all this MK9 and MK2 mumbo jumbo? I know what ODIN is because I helped my girl's little brother root his Tab 3 10.1, but all this other stuff is foreign to me.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] cruise350:
Those are just the firmware versions, they are the last 3 digits of the current firmware codes. Welcome, from a fellow past Evo user. I want to start out by warning you. YOU HAVE THE 720T, this is a totally different phone from the S4 that the majority of users in this forum have. You have different firmware, modems, and recoveries. So be careful flashing things to your phone that aren't specifically made for it. Like I said, be careful. You will see a lot of people use the term full tar file. This would be similar to the HTC RUU file. You would for example, flash the full stock tar to your phone through odin to return it to stock condition. This does not reset data however like the HTC RUU would. Also, the S4 doesn't have locked bootloaders like HTC, but with 4.3, Samsung introduced the knox enabled bootloader, which your phone has. This means, that when you install a custom recovery to your phone, it will trip a warranty flag that currently can't be reset. Enjoy your phone and make sure what ever you install is known to work for your 720T version of the phone.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] negativzeroe:

I got a sprint S4 and it didn't come with a SIM card. When I activated it, I didn't have a SIM so I just told it to use the one "that came with it". Now I have a "missing SIM card" notification all the time. What do I need to do? Get a SIM card from sprint? SIM unlock? I'm confused about this, I've had sprint forever and never needed a SIM card for anything. </n00b>
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] cruise350:
If you bought your phone new, go back to the store and demand a sim card from them. The sim is needed to receive LTE. If you bought it used you need to go to Sprint and get one or you won't receive LTE signals. You may have a hard time getting one since they are supposed to be matched to the phone.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] hAvAAck:
Thanks. Ugh, used!

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] cruise350:
You need to get the SIM card from sprint. There is no other way to receive LTE without the sprint SIM card in your phone. Regardless if it is unlocked or not. The sprint s4 is not compatible with other carriers LTE signals.

Where to learn terminology?

I am new to XDA, and have only been using my Galaxy S4 as supplied by Sprint so far.

I want to learn about flashing roms, hotspot mod, recovery and stuff.

I am technical, but have not been exposed to the "phone scene" terminology.

My Galaxy S4 is stock MK2 firmware. I wish to get pointers where I can learn the following;

- What do the terms ODEX and DEODEX refer to?

- What is a module like CWM or Philz Recovery? How are they installed? Are there pointers to usage instructions?

What do they do?

- I see in the various forums discussion about putting your phone into Download Mode, Recovery Mode, etc.

Is there a page somewhere that defines what buttons do that (instructions/guides)?

So far, I have read about and downloaded odin 3.07 (a rom flashing program for the PC), and also CF auto root,

but I am not going to attempt them until I learn more.

Thanks,

This a 'noob friendly' post.

BUT really you should be able to find the answers to every question you asked if you spend some time searching, reading and then reading some more. I cannot stress how much better off you will be if you read through the stickies and how-to's yourself AND read all the way through the whole OPs (original posts AND follow-up pages). Yes I know some posts are a dozens or hundreds of pages long, but you will NOT be sorry and will definitely learn. You will also keep yourself from turning you pretty device into a nice shiny paperweight.

Again ALL the answers to the questions you asked are easily found. And just about all of them here in this forum section (Sprint Galaxy S4)

example:
