Latest release of Marshmallow for the L720 and L720T from Team Octos. I put this on a L720T and now in the phone info it says its an L720

https://basketbuild.com/devs/Team_Octos/release/jfltespr

Latest weekly build. Looks like they've been staying busy with it. The last date in the changelog for the latest release is 3-9-2016, last date in the log for weekly is 8-20-2016.

I installed the i9505 version (jfltexx) of CM13.1 on my L720T. It now says my phone is a GT- i9505. Although it is Sprint branded, it works well using this ROM on the AT&T network. It also picks up LTE data on band 2.

DELETED
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Please help. I'm on stock OK3 and nova launcher on my sprint 72OT

I noticed today that when I tried to use the copy log feature in twrp. it says it copied the log to \external_sd

Then I go to file manager in twrp and I can see the log. Then I reboot and open my fx explorer (my file manager program with root permission) and the log file is gone.

Next...using my fx explorer I create a folder on my external sd card and then create a text file in the folder.

I exit the Explorer and reopen the Explorer and everything is there including my new folder and text file.

After I reboot, everything is undone and the SD card is back to the way or was before I did anything.

So when I reboot, it undoes all changes made to sdcard. The changes stick forever until I reboot, then everything is undone.

What is causing this?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bilgerryan:
It's an external sd write permission bug... Hold on, it's a pretty easy fix, I know it is somewhere in system/etc/permissions

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Thank you. I will hang on to this and give it a try after I finish my current attempt. This is a very strange problem because it's not the normal kitcat external sd card write permission issue. I used the sdcard fix app by nextapp a long time ago (and just for grins did it again yesterday to see if it would fix this).

Since executing that app (which fixes the KitKat permissions) on OK3 a long time ago, I've always been able to write to my card and the changes always stuck after reboot. in fact my wife has the same set up as me and her is still working fine. suddenly my changes (newly created or deleted files and folders) only stick until I reboot, and then it's all undone. Weirdest thing ever.

It gets even stranger, because I just pulled the sd card, stuck in my desktop pc, deleted some files off of it and created a folder (all on the sd card), rebooted my pc, and everything was undone again. All the files were back on the sd card, and the folders I created were gone again....so weird.

So it appears to be a corruption with the File Allocation Table (exFAT) or format corruption of some kind. I've never seen anything like it, so strange.

Currently, I copied everything off of the card to a folder on my pc, now I am re-formatting the card with the slow option, then I will attempt to create files on the card again, and reboot my pc and see what happens.

I know this all sounds crazy, and that's because it is....lol
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
WOW...Windows Explorer almost finished formatting the sdCard after 30+ minutes, then erred out, and now all the files are back on the card again, as if they were never erased. This is nuts. Guess sd card has gone defective or something.

I keep trying to reformat it, with the quick options, and it tells me windows is unable to format it.

I don't want to start my phone up without it, and without the data on it, because I have a lot of apps that I keep moved on to the sd card and they will all lose their hooks and go nuts if it's not there.

I'll try to use some other devices like a camera to format the card, and see what happens.

I just bought/ordered a new 64gb card online. I believe my card died and can no longer be written to by any device. The good news is that it is readable.

to be continued....
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
My new 64GB card came in today. Problem solved. Everything works. I was able to copy everything off the old card over to the new card, stuck it in my phone and booted up. I can write to the card and everything sticks after reboot. The old 64GB card still cannot be formatted (errors out). For some reason, it cannot be permanently written too, and can only be read.

It's so weird how both the desktop PC with windows 10 and my android phone will appear to let me create folders and files on the old sd card, and delete files on the sd card, but after reboot everything is undone as if I never did anything to the card.

Personally I don't understand why the changes are not committed to the card until shutdown but there it is....Some how the exFAT (File Allocation Table) is caching or something, and the changes are never really being written to the card due to some sort of write problem on the card. This is further proven by the fact that I can't format the card with my phone, camera, desktop PC, or any device whatsoever.

Bottom line, a new sd card acts totally different and solved the problem :)
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
I forgot to mention that I also noticed on the old card that I could not complete a TWRP backup anymore. I was getting an error 255 at the end of the backup. This was my first sign that I had some sort of problem. This eventually led me to find out everything else I previously described.

On the new card, TWRP completed backup with no errors.

It's nice to be back in business ☺

Good day guys. I have tried every way written here to unlock my phone.

I haven't seen a way to get the MSL and unlock once you are on lollipop (OK3).

From my last research, galaxy tools fails to unlock on lollipop OK3 even with root. I bought a replacement 720T some time ago on OK3. I Installed TWRP, gained root, and no version of GT will unlock mine. I have also heard this from others.

GT worked on earlier sprint android releases, but sprint changed the game or patched something after that.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] 124chase:
I am not sure how the MSL will help you sim unlock your phone. I was on lollipop with OK3 and had to downgrade to KitKat and the MK5 modem. After doing this I was able to use SSU and galaxy tools to Sim unlock. I have been running a Sprint banded SPH-L720T on the AT&T network. With the triband phone, you can get LTE on band 2 if it is available in your city. Also, use the jfltexx rom, not the Sprint rom. You can do this with some work.

1. Rooted my device using KingoRoot (720T / OK3 lollipop)

2. Installed 3.1.5 gtapps

3. Open the app and grant root permission

4. Install update 3.1.8

5. Reboot

6. Open gtapps 3.1.8. MSL will be shown (you don't need it though)

7. Click Unlock

8. Reboot

9. "Invalid Sim" prompt will not be there anymore.

10. Change Mobile network from CDMA to UMTS/GSM

Just call them back and ask for an unlocking number. It should be pretty basic. Just so you don't run out if time, call when you have time. Instead if browsing through forums and posting stuff on XDA just take that time to call and ask for an unlocking number. Pretty simple solution. Thumbs this up if it helped you:)

---------- Post added at 04:30 PM ---------- Previous post was at 04:24 PM ----------

All you have to do is call your carrier and then request an unlocking. If you have a globe lock, it is a simple fix. Replace the old carrier sim with the new carrier sim. Your phone will ask for an unlock code. If you don't know you unlock code, call your CURRENT carrier and ask for an unlock code. They will give it to you. Enter it to your phone and BAM! Your phone is unlocked! Hoped this helped you:). This works in the Philippines by the way.

While looking at the specs of the GS7 and GS8, I realized today that Samsung removed the IR transmitter (also called IR Blaster or Infrared) from their newer phones. So you can no longer use your phone (GS7 and newer) to control the TV in your hotel room or any non WiFi capable TV at your house or restaurant.

This made me appreciate my GS4 again. I didn't finish looking at GS5. It may still have the Transmitter. But can't remember if the GS5 has removable battery either.

This "device certification" doesn't sound good.

If you have the new play store that just came out, open play store, go to settings, tap on device certification, let it open your browser, and read the page that comes up.

If you read between the lines. I THINK what Google has done is add a root checker to the play store and if your device is rooted or modified from stock too much (apps frozen, etc.), then we will no longer get any app updates sometime in the future.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
It may just be that because the OS is to old (lollipop) they will no longer allow app updates in the future. Can't really be sure at this point.

I have been receiving a lot of app updates immediately after this stock play store update....so time will tell.

If they have added a root checker, I'm going back to apple.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bilgerryan:
Really not surprised.... They've shifted their focus to being more secure than Crapple.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Security is very important, but Google forgets what made them a crapple competitor and major player..."what droid gets, droid does"...and other commercial phrases. In their beginning, they touted their openness and flexibility.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bilgerryan:
I think it should just come down to agreeing with some terms and conditions. By rooting you realize your security is compromised, some apps won't work, and you are at fault and responsible for anything that happens after agreeing to these terms. Do you agree? Congratulations, you are now rooted.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
That's a good example of what fits with their original/old strategy that made them an apple rival ("What droid gets, droid does") and gained them mass market share.

However, they seem to be abandoning this philosophy now that they have a foot hold in the market.

PL1

So very interesting...a couple of months ago on my Sprint 720T, I reinstalled OK3 from Sam mobile, and about the time I re-rooted my phone I got a android system update notification from Google play service.

I was confused because Sprint has never listed a newer firmware than OK3 on their site, and I think all of us were of the understandingthat that there would be no more firmware updates for the GS4 720T. Needless to say, I didn't want to deal with it at that moment, so I hid the notification and decided to come back to it later.

I just turnd the notification back on, and I examined the files in the OTA update.zip. The firmware is called PL1.

I made a copy of the OTA update.zip file on my SD card for backup. It is 286.7MB and does not match any previous OTA.

When I have time, I will try to install the update. Not sure if I can do that with root and twrp installed.

So I have to figure that out first.

I guess I also need to see if it is listed on the Sam mobile site.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Just checked sammobile. PL1 is legit for 720T, and it was released on 2/9/2017. I am not sure why sprint never posted it on their site.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bilgerryan:
They're usually a few months behind and I may have exaggerated a bit, but the last version of Wicked X that I released had the security update and PI2 in the build.prop so there's no update nag.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Good to know for your wicked X users. Thanks you.

I'm hoping that PL1 5.0.1 also introduced some stability updates in addition to security.

On a different note....I remember some user certifying on here WiFi calling as working on another rom a Shorey time ago. So it would seem that it is possible to make WiFi calling work on non stock ROMs.

Is WiFi calling working on wicked X now?
