The hidden code for Sprint S4 720T on stock is ##3282## (not *#*#3282#*#*)

Bands 26 and 41 are stock enabled on 720T. However if you run a custom rom you may activate and deactivate bands to enable the tri-band.

I know C-Rom lets you modify bunch of things including bands. On C-Rom the WiFi signal show exclamation point but if works flawlessly when I tested. I had to modify the SMSC gateway number (I think because I dint wait for activation).
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
I'm on stock 4.3. Do I need to do anything or am I automatically getting the tri band experience.?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] frukyyy:
Nope tri-band broadcast is activated by default and anyway you cannot modify much of bands on stock.

Just curious why you stay on stock 4.3.. If I had to go back at 4.3 I would get sacs.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Frukky,

Thanks. Im staying 4.3 for now because I'm still hoping for a saferoot method and my 4.3 does everything I want. Eventually I may still upgrade and just use cf-root. I have never readup on cf-root and never used it before. I assume it replaces the kernel and that's why it trips the knox? Replacing kernels makes me nervous lol.

Again, I may not even know what I'm talking about because as I said, I've not had time to look at it.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
All,

I got a message frome bthrone79. He says he uses OctOS Rom and that everything works on that rom on the tri-band. So this may be a first confirmed fully working rom. If some one else tries it, please let me know. Check the spark and wifi.

Secondly, he is still trying to get his power Jack fixed on his laptop and is a few $$$ short. I may have a PayPal address for Him soon for anyone that wants to donate a few dollars. Will keep you posted.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Bthrone79 paypal address for donations is rcovington79@gmail.com

If you feel safer having confirmation on this email address, it is also listed in his xda signature.

Yo guys sorry for the disappear started new job had lots of weeks of training in fact still training after 10 weeks I've been running OctOS unified builds and from what I can tell everything has been a solid run I get test builds and release builds. Now with spark being lost that's hard to understand due to it being a radio.

Is this a new rom for the L720T
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bthorne79:
Its for 720 right now the 720T will still need a recovery to flash the custom ROMs which is still not available for some reason I talked to Cnexus about adding it to philz never heard back maybe we all need to start hitting him up. :)
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] carolinavenger:
Well I've had no luck getting WiFi to work, sorry to report. Went back to my backup again until someone more knowledgeable than me can figure it out. One last question: does anyone know where to find either a zip or tar of the stock 720T KitKat rom/firmware? A few of my apps have gone a little wonky since the restore and fixing permissions didn't help so I was going to try a clean install of the stock rom, but the only ones I can find are NAE, not NAF :(

Robtheslob's update.zip didn't work for me, but I did find what I was looking for on sammobile (took me a while; I've only had HTC phones before this, still getting used to the world of samsung). If any future travelers are looking for the full stock kitkat firmware, go to sammobile and search sph-l720t. I'd post a link but it won't let me. noob problems. :)

The Gt9500 is the international S4, you can't just take one phone and flash the firmware for another, otherwise Samsung would release one phone model and firmware for all the carriers. If only it was that simple.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Thanks and I agree with bilgerryan, that is correct. Just wanted to also say that I wrote "no comprende", because I wandered if Isiel worded his question correctly.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Isiel:
Thank you for your reply. However I'm confused because my S4 had GT-I9500 firmware when I got it from seller. I realised my S4 were SPH-L720T when the seller upgraded my android to 5.1.

If it's impossible to get to GT-I9500 in my S4, how do I get rid of Sprint default applications and getting my Sim card and contact in it working in my S4?

I'm from Singapore.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bilgerryan:
You can just delete the Sprint stuff. Not sure what you mean by the rest.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Isiel:
Thank you for telling me how. Currently my phone isn't able to get/detect my simcard's contacts and it seems that there isn't any button to display simcard's contact under contacts to display function.

EDIT: Further problems i face is that the voicemail as well as there is a phone number that isn't mine currently in phone status. So if i could delete the voicemail app and make the phone number unknown, it would be great.

Therefore i'm asking if there are any solutions on making it work. If you do have any solutions, i would love to listen to it. :)

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] darkstar91pt5:
I decided to use odin for my rooting purposes; but, I can not get odin to detect my phone. I tried different cables, ports, updating usb drivers, different versions of odin including the latest one and it won't detected both when its on and download mode. One thing I do notice is that in device manager on my windows 8 pc there caution sign giving me a code 31. It says the device isnt working appropriately because the driver did not install correctly. I am thinking of doing a factory reset on my phone. Any help would be greatly appreciated.

thanks

I've gotten it working, I achevied root using odin and a Cf Auto Root tar that was the most current one from the first page of this post, op only had a highlighted link so I never caught the name, I'm running stock touch wiz. So I can confirm the latest OK3 is Root able using http://click.xda-developers.com/api...int Galaxy S4 | XDA Forums&txt=this 720T file

I had to get a new uicc "sim" and call Boost for my LTE to work that was all I lacked.

I do have/pose a question can my msl contain a dash mark? I used an app called Phone Info > went to other tool's > service mode (Root)> Main menu>Cdma>Msl edit( low and behold my Msl was shown as Msl=-533**** , last 4 digits not shown by me) but after trying to input it under *Data* it wouldn't work. So should I include the dash mark or being my ph is Boost /sprint would it have a sprint msl and then one put in by Boost as well? Thanks Guys!

The su binary is out of date.

Hi. After I rooted my sprint SPH-L720T on OA3 from boost mobile I did used Root Checker Basic and it says "root access is not properly installed". Also, my phone gives me the notice, "the su binary is out of date". King root made my phone give me this same message su out dated. I used "su update fixer"and it didn't work. Please help me .what should I do? Also, if I root an android device, does a factory reset and internal memory wipe has to occur as part of the rooting process because this didn't happen on my phone.

Thank you in advance.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] tha*noobster:
If you use odin and the link I posted above to achieve root imI'm pretty sure it installed an Su that did not need any updates to binary.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] darkstar91pt5:
I used your link and related file and I got the same issues. This time I tried Kingroot and was able to get root access. I still want to replace king super su with supersu. Any suggestions?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] tha*noobster:
From what I've read Im not sure you can replace king super su with a different type, granted I don't know everything tho. When you used the link and the tar was super su included in the file? Also I've never used king root but if it's similar to the method I used your going to have to unroot manually then clear your cache and uninstall any files related to the previous king super su and kingroot before rerooting.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] darkstar91pt5:
These are the files included in the compressed file you linked:

CF-Auto-Root-jflterefreshspr-jflterefreshspr-sphl720t.tar.md5

Odin3

Odin3-v3.10.6

tmax.dll

zlib.dll

As the OP1 instructed on this thread, I used Odin to root phone with CF-Auto-Root-jflterefreshspr-jflterefreshspr-sphl720t.tar.md5

I was under the impression Supersu was going to install automatically and even after rooting this way I couldnt install maually.

I am a noob so I dont see a su file in the compessed folder. Am i Mistaken

It's a whole lot easier to flash TWRP then boot directly into TWRP and flash SuperSU, then boot into ROM and open SuperSU

Sent from my SPH-A120
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bilgerryan:
It does not include the SuperSU app, CF Auto Root only installs the Superuser (su) binary to system/bin, then you simply download SuperSU from the Play Store and update binary within the app.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bilgerryan:
It's really about the same difficulty, but most of us know that root isn't as useful without a custom recovery... so we skip the step of rooting and just flash TWRP. Some people just want to root the stock ROM and debloat, just depends on what the reason you're rooting for.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] mattzeller:
Seems silly for people to keep stock recovery when rooting, since you can't make a nandroid

For some reason, Touchwiz ROMs do not work on my L720T. Aosp and CM run perfectly, but TW roms dont. They flash and boot fine, but after one reboot I get a persistent com.android.phone has stopped popup that wont go away and phone loses signal. Any rom ive tried, rooted stock OH1/OK3, a emptygalaxyrom 5.0.1 for the vzw variant (ive used this rom a lot before has always worked perfectly, vzw custom tw roms are compatible witb sprint), and full stock oh1 and ok3 firmware via odin. All get that same issue after one reboot. F.reset fixes but returns after rebooting again. Tried wiping all system data dalvik cache internal and external storage than flashing stock from odin

Same issue

Have not messed around on this device. I did flash stock odin OH1 and accpeted ota to ok3. After that Ive only used jdcteam aosp 6 and a cm13 for jfltespr.

Im thinking this has to do with the ok3 ota but im afraid it might be hardware, though not sure why cm and aosp works fine then. Any ideas? Ive tried everything to no avail
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bilgerryan:
you keep mentioning that you've tried Verizon ROMs, I terrors flashing one and got the exact same thing you are mentioning. I don't think that they are as a compatible as you think, try using ROMs that are actually for your device, you can really screw up your device flashing stuff that isn't made for it.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] allanlgz:
Did you manage to fix? If so, how did you fix the issue?

I mentioned flashing the vzw rom, but last time I had flashed it was a month prior so I didnt really think it could be that. I suspected the sprint OK3 ota update as problems begun right after that. Flashing stock sprint via twrp or odin doenst fix the issue btw at least for me
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bilgerryan:
I never did the OK3 update, but I had to Odin OH1 update to fix it.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] allanlgz:
What wipes did you do?

I tried wiping system caches data dalvik and internal plus externa, then flashing oh1 via odin, no fix

Thats why im afraid its hardware but puzzled as to why cm and aosp works, been working on trying to fix this for days

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] life-in-3D:
Android M

Hey all, I'm new to the forums sorta, signed up a while ago never really posted much, I'd like to get back into modding my phone and I have a couple questions....

1.) I'd like to run android MM from Team OCT Os on my l720t, I tried it out and all works well except bluetooth calling, neither end gets any audio? I think it could be Modem related because my current modem is OH1, could that be the issue what do you guys think?

2.) If that could be the problem how can I flash just the modem using odin? I have been unsuccessful so far in finding an OK3 modem.bin to flash (CP / Phone slot right?) does anyone have one they might be able to link?

Any help is greatly appreciated thanks very much all!
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bilgerryan:
Have you tried asking in the ROM thread to see of ours a problem with the ROM? That is far more likely than the modem being the problem.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] life-in-3D:
I can't yet... being that this is post #5 I do not yet have enough Q&A posts to allow me to post in the development threads... so I figured this was the next best place, possibly the best as I know many of the people in this thread will have more experience with multiple roms and might have seen this issue before. I had a similar issue with 5.1.1 Oct-L, Bluetooth service would stop every now and again and the only way to bring it back to life was a reboot, since I've seen Bluetooth problems in multiple rom versions, I though it could be the modem

edit: yeah I asked in the thread XDA must have removed the rule that dictated one needed at least 10 posts in General and Q&A before they could post in dev... still if anyone has any suggestions that would be awesome, would love to update the modem to OK3 if anyone has a .bin for that still, I got the sammobile firmware not sure if I can get the modem from there?

thanks again all!
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] life-in-3D:

I tried to deodex the OK3 rom for the SPH-L720T using Superr's kitchen.

In short, you can't. You can update the modem only, it's in katodragon's OK3 thread. The correct process to fully update is: make a nandroid backup, Odin OK3, Odin TWRP or whatever recovery you use, restore nandroid.

Thought for the day...awhile back, I realized that everytime I recieve an app update on my S4 720T phone, google automatically moves the app off my SD card and back to internal memory. I then have to move the app back to SD card myself. This is a real pain since app updates are so frequent. It almost seems like the updates increase after you initially move the app to SD card, and perhaps samsung and google are teaming to stop you from using your SD card, so you will run into unwaranted memory capacity issues, and buy a new phone/upgrade.

This fits with the fact the Samsung eliminated the expandable SD card from the S6 and went with internal memory only (like iphones).

However, it seems like Samsung has made a U-Turn with the soon to be released S7, which touts an expandable SD card again (up to 200GB ).

Enough of all that, and I'll get back on topic now. If anyone has any good tips on how to stop app updates from moving apps off of SD card and back to internal memory, I'm all ears.

Other than this, Im still quite satisfied with my 720T.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bilgerryan:
Turn automatic app updates off in the Play Store and actually read the change log when an app says it needs to update, 90% of the time it's a fix for a very specific thing that if you aren't experiencing or adding a feature or something else you don't care about.

Thanks. Certainly a valid option. I've not done it before, because I like the convenience of not having to go look through everything all the time.

I do like to look at details of some apps but not all.

And many times the developer just says generic things like "bug fixes". Might be significant and might not. I think sometimes it might have been bad and they don't want to tell everyone the significance of what they fixed.
