Finally Rooting my moms phone....

Im finally getting around to ugrade and root my moms new S4. Im an HTC user my self, so the Samsung Rooting methods are a bit different than what im used to...These are the steps im going to take...Please let me know if any of them are wrong...Thanks in advance...

1. Curennty running NC6 baseband...Going to Falsh L720TVPUBNG5_L720TSPTBNG5_SPR.zip through Odin

2. Run TWRP SUPERSU METHOD for jfltespr To acquire Root access and flash TWRP Recovery

After that, I should be good to go to flash any custom Rom???? Also, Please let me know if one Recovery is preferable over the other....I personally run TWRP on my EVO LTE and like it allot..But dont know which works best with this phone...

Thanks.....:confused:

---------- Post added at 05:20 PM ---------- Previous post was at 04:44 PM ----------

Can anyone point me in the direction of the NG5 Odin tar file L720TVPUBNG5_L720TSPTBNG5_SPR.zip

My hard drive crashed and lost the one i was waiting to use...I tried looking on Google, but the download site it took me to was not working...

Thanks...

Edit: Nevermind, I found the file on SamMobile...

Has anyone had any luck moving apps to the SD card on this phone? Just bought a 64 gig sd off amazon (pre black Friday sale! $30 bucks!! Wooo!) ... I have rom toolbox pro, but it for some reason won't let me through that app and I don't see an option in my control panel (I'm rooted with cm11 running).

Anyone had any luck with this?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
OK I have to ask to see of anyone has a solution.

I have a sprint s4 sph-L720T phone.

I use stock and cm11 roms and gps test shows multiple satellites and gets locks in a few seconds.

When I try other roms such as for L720 the only thing that doesn't work on those roms is gps. Gps test shows not even one satellite at all.

So am I destined to never use any other roms besides these two or is there a fix?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] JerryGNYC:
From my Evo days I seem to recall a file named gps.conf (or similar). To start, I'd locate and compare copies from each ROM.

That's because home button wake is not a part of lollipop source code anymore. So it has to be coded in.

HAPPY THANKSGIVING? to all
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
OK I guess I need schooling again :).

I have a Samsung SPH-L720T on sprint.

I am using twrp 2.8.0.1.

My steps to installing a rom are:

-wipe > advanced wipe

I then select system, internal, data, cache, dalvik, everything on the list except for USB on the go and microsd.

Then I slide the bar at the bottom.

Once done with that I hit the arrow back to the home screen and go to install a rom and pick the sdcard and go to where I have roms and gapps installed.

I select the rom first then gapps, then boot to system.

The issue I am having is any and all aosp roms I try the data or gps do not work. Mostly it's just the gps. I've tried about every rom out there that is L720 based with no luck whatsoever. Gps shows no visible satellites in sight and sits searching for gps signal. I have also tried replacing the gps config file from stock tw rom which I know works as well as other gps config files I've downloaded, and using those gps config files instead and still no satellites at all. Gps test shows not a single dot on the map.

I revert back to stock tw and everything works.

Roms I have tried and have tried multiple of each are:

-Cm10 and cm11. (Cm12 I am waiting on because it's still in test stage.)

-beanstalk

-carbon

-omni

-Octo

-nameless

I'm sure there are some I missed but I've tried everything.

I've tried both ng5 and nc6 modems and still no luck.

I updated when ng5 came out so could that have messed something up?

I've tried all this with and without gapps installed, does it matter if it is or isn't inatalled?

Could twrp be any kind of cause to this maybe not wiping correctly or something?

I have talked to someone else with this exact same phone and they don't have any issues at all like this. They can run all the above with no issues what so ever.

Am I just destined to never use anything but a stock tw rom?

I'm basically grasping at any sort of fix. I hope someone can help me.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] BradGrenz:
My experience has been similar to yours. Pretty much the only roms that reliably have GPS working are those based on TW. Negalite worked for me. So did Sacs v6. I'm using the cm12 test build from 11-24 and GPS works in that so their appears to be hope for lollipop aosp roms going forward even if kitkat based roms never get sorted on our 720ts.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
Very odd indeed. It seems as if some of the T users are fine flashing stuff and things work OK yet others with the exact same phone have issues. I'm curious now as to what the difference is in the 2 sets of T branded phones.

I have tried both modems so it can't be that. (Scratches head) I really don't get it.

What's even more puzzling is at one time I didn't have gps issues at all. I used a few aosp roms and gps work flawlessy, namely cm11. Now nothing aosp works with gps not even cm11 works now, when it did before.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bthorne79:
I wonder if it has to be with the people who took or Odin the ng5 I never did I only took mine to NC6 and on MK5 and NC6 I don't have any issues it might be in the NG5 bootloader but I'm not sure if you can downgrade the bootloader I know on the s3 you could not because of the knox built in to bootloader

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
Just a little fyi. I was on ng5 and used an official nc6 firmware Odin file and flashed it via Odin 3.10.

Results are some how the bootloader is locked to ng5, and...... The firmware doesn't re-do the baseband. I am currently on nc6 firmware with ng5 bootloader with ng5 baseband.

Just a info people may want to know.

I'm not sure how sprint managed to lock ng5 bootloader but it seems they have done so because as much as I want to flash back the nc6 bootloader it seems I'm stuck at ng5.

Display assembly/replacement

After breaking the screen on my L720T, I've learned that it isn't the same midframe as the L720.

The correct display assembly for the L720T is the one that goes on the M919 and I337 (SGH-I337 and SGH-M919, T-mobile and ATT) presumably the international one will work too. The differences are subtle, but the capacitive button cable on our L720T is short, like the one in the first image here.

[IMG="shortcable"]http://i.ebayimg.com/00/s/MTAwMFg3NTA=/z/tsMAAOxyHIlTYL4B/$_57.JPG[/IMG]

The L720 has a longer one, seen here:

[IMG="longcable"]http://i.ebayimg.com/00/s/MTAwMFgxMDAw/z/w1kAAOSwofxUeYdW/$_57.JPG[/IMG]

Also, the charge port assembly has two little nibs it sits on, and in the L720T & M919 etc they're farther apart. I tried to stuff it all in but to no avail, off to see if I can return it and get the right one.

Reference w/ more pix: http://www.ecever.com/blog/differen...4-i9500-i9505-i337-m919-l720-i545-lcd-screen/

Hope it helps and you don't order the wrong assembly like me!

i flashed TWRP 2.8.1.0 on my sph-l720t and so far it looks like it is running good and i'm going to try the cm12 cyanogen mod and i'll probably update when that has happened
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
From what I think I've learned on this thread, baseband and modem are the same thing or are linked and apparently the modem will not downgrade with a firmware flash. Have you tried flashing the NC6 modem listed in the downloads section of the op?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
Correct on both parts. So anyone wanting to change the baseband/modem will need to flash it via an Odin baseband file. For me that wasn't a concern really as I knew I could just flash the file and reboot and it would fix that part of it. Sadly though the bootloader is what I was trying to revert back to and the firmware didn't change that either because the newer bootloader is locked so I'm stuck on the new one unfortunately.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Thanks and one question:

If baseband will tell you which modem you are on, how do you tell which bootloader you are on?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
I use a program on the playstore called phone info, the one specifically for Samsung phones.

Also be aware anyone who upgrades to ng5, from many hours, days, and weeks of testing that if you do upgrade to ng5, it seems as if gps is broken in any and all aosp type roms. For me I sat one day and downloaded all possible aosp roms for this phone and everyone of them when you run gps test app it shows as not a single satellite visible at all. So if you want to use aosp and have gps don't update to the latest firmeare ng5. Sprint or Samsung really plugged some holes making the use of other roms other than tw roms impossible to use, because gps breaks. The rest of the rom works aside from gps. If you don't mind gps working, or don't even use gps then your fine to use aosp roms.

Just a heads up.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bthorne79:
Another way is with terminal app and type su then getprop
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Another way I just realized is with galaxy tools. Bootloader version is in the upper left hand corner.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
Yeah those all work. I just found the app was easier for me
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] tabormeister:
Did you have a solid GPS fix in touchwiz before flashing AOSP?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
I did. Just because I am a techy and like to know how things tick I've tried both ways. Still no gps. Bthorne79 and I spent time trying to figure out why and what the difference in his phone and mine was. There is only one single difference and that is the bootloader. He is still on nc6, I'm on the new ng5. His works and mine does not. He can use multiple aosp style roms and has no issues at all, while I on every aosp rom have no gps.

Difference? The bootloader revision.

That's what lead me too the last ditch effort of trying to flash back the stock nc6 firmware, but it didn't work.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
I wander if the ng5 bootloader is the direct cause of the gps issues.

Can you tell us what are the other negative impacts (if any) of the seemingly locked bootloader?

I'm hoping we are all wrong and sprint has not begun locking bootloaders and there is still some way to overwrite it that we haven't thought of yet. (Optimistic :) )
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
From my findings of many hours and testing and bthorne79 can verify this, other than gps the rest works fine. Every persons experience can differ but for me everything worked except for gps.

With tw roms everything works fine, but that limits our choices pretty drastic.

With that said I will throw this out there in hopes someone will take on this task and make us T phone users a working s5 rom. I would be willing to set my phone aside for testing purposes to achieve this. I for one would be extremely greatful and I'm sure there are others as well.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
So it sounds to me like this ng5 boot loader lock is not the same detramental thing that other carrier boot loader locks are. Thinking of att which if I remember correctly on att, if you mess with the boot loader it bricks.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Crysiswar:
It didn't work
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
You got a modem download file and flashed it via odin?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Crysiswar:
I don't have a modem download file
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
Not sure. I do know I've tried to downgrade via the official firmware and the bootloader and modem stayed put on ng5. I can flash the modem back and forth no problem so that leaves only the bootloader left. It's somehow locked down where it will not be touched or perhaps it's like the modem and isn't included in the firmware, or maybe Samsung knows that it's locked and decided not to include it in the firmware.

I am on limited income because I make min wage $7.50 an hr. So since this latest Samsung debacle I am pretty well hanging it up with the tw phones, so I am currently looking at a Samsung nexus 4g 32gb phone. I can't afford much and this phone is $89 so that's around my pay scale.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
The modem download file is in the downloads section of the op. Goto bottom of post one and look for NC6 modem.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
That's what I'm thinking. I don't know what magic bthorne used to pull out the modem file but maybe he can figure out a way to do the same for the nc6 bootloader.

This seems like a YMMV kind of situation. I'm on NG5 with perfect GPS on CM11, as I'm sure others are.

My only issue is randomly texts will come through a bunch of times as duplicates, but I'm sure this would be fixed by a clean flash and profile update. (I'm lazy)
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
Hrmm odd.

So your bootloader is ng5?

Your not referring to baseband are you?

I also noticed you mention about clean flash. So your doing dirty flash every time?

Update:

Ok I did some more testing.

I accidently downloaded cm11 nightly back in Feb of 2014. I happen to notice gps worked, so I stumbled on the android version for whatever reason I happen to look at it and it was 4.4.2 android.

A light-bulb kinda kicked in and I decided to test out my theory. I Tested out Cm11 4.4.4 nightly, another 4.4.4 rom, Beanstalk 4.4.2, cm11 4.4.2, and carbon rom 4.4.2.

Of my findings ALL the 4.4.2 have working gps, while the other two roms that are 4.4.4 roms, the gps did not work. I had the same result with no satallites showing at all on the 4.4.4 roms, while on the 4.4.2 gps locked within 1-3 seconds and was very accurate.

It seems as if maybe NG5 is still the culprit, I'm certainly not ruling that out, because someone else with this phone uses 4.4.4 and gps works on it.

For now until further information is presented and/or tested, anyone on ng5 that happens to not be able to use gps at all, try using a 4.4.2 rom, it will most likely work fine.

I for one am happy to find this because this now opens back up my (and others I'm sure) choices of roms again, just as long as they are 4.4.2 roms

I am also trying out Android L and gps works on it as well, it's just 4.4.4 that I have the issue with gps.

I hope this helps some people out, because I know I was getting rather irritated at the fact I was being limited to my roms I could use.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] tabormeister:
Nope! See screenshots. (Baseband is also ng5 though) Gps is killer every time. I'm inside a huge building and it locked in two seconds.

I clean flashed from ng5 to CM11 M8 but I've been flashing the M builds dirty since.

I thought nfc was wonky at first but it seems perfect now. Only other weird thing about this phone I've noticed is the lcd midframe being the same as the gsm version.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
Yeah GPS can always be finiky inside.

Try a 4.4.2 ROM, I'd be willing to bet you'll have way better luck. I know I have since I found it using 4.4.2 works way better. Every ROM I've tried locks within 1-3 second and is very accurate.

In in the process of trying to figure out what files control the GPS so I can swap the files out of 4.4.2 and replace the 4.4.2 with the 4.4.2 files.

So anyone know what files control the GPS?

Please the baseband unknown problem is making my phone useless can anyone help? I posted before and your solutions didn't fix the problem. Does anyone have any idea how to fix it
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
Only thing I can think of is your phone is a different model of Samsung s4, maybe the International brand. They have so many variance of the s4 out.

Make sure that yours is a 720t phone and not a different one such as the 720 or I9505 something similar.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Crysiswar:
My phone is SPH-L720T I'm

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] tabormeister:
To clarify, my GPS is perfect. I am on NG5 bootloader and baseband. I'm on CM11 M12, which is 4.4.4. It locks no matter where I am, inside or outside in 1-2 seconds.

You want to look for gps.conf and sirfgps.conf in /system/etc. I'm sure there are others but those are the two I know of.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
Hrmm. I am not sure then. Those modem files when flashed with odin should have changed it. I've done from ng5, down to nc6, and back just the modems. Sorry I can't be more help. It is definitely odd.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] tabormeister:
If you pull out your battery and it says sph-l720T there, then you should do a clean restore with Odin or Kies and see if that fixes your problem. If it doesn't, you probably have a hardware issue.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Crysiswar:
How to do a clean restore with Odin
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
There is a Sam mobile somewhere I'm sure bthorne79 has linked both nc6 and ng5, possibly in this thread somewhere.

Grab the ng5 firmware file and flash in Odin. They are zipped so make sure you unzip them and there should be a tar file in it. Open Odin, place the tar file in PDA slot hit start and let Odin do its thing.

It will probably wipe everything so make sure you back up the stuff you want to save before hand. You will also have to install a custom recovery and SuperSU again to.

All,

After countless hours of diagnosis, I finally feel I have nailed this tether bug down. Keep in mind I'm stock NC6 with towellroot and that may make a difference.

In short, If you have both the wifi tether router app and the native tether mod installed, and when you start native tether you get the error pictured below a few seconds later, just reboot your phone and do not start wifi tether router first and exit. Native will then work with no error. If you start wifi tether router even one time and exit, the native error will return until you reboot.
