having trouble!!!!!

I have been looking for a 4.4 update for my sgs4. I kept trying to do OTA however the software would update but it was still 4.3. I was rooted at the time. So I flashed the NAE firmware which was actually just the modem. It was fine. I was looking for a cool rom to put on it so I went back to MF9 but the build was at Mk2 the whole time even with the NAE. somewhere along all this flashing the wifi wont turn on I have no sound on the device and I cant boot into recovery because the yellow triangle comes saying something about there being some software that is not samsung. I have tried flashing entire firmwares but all different versions of odin are not responding and to top it all off this is my daughters phone and all she wanted me to do was make it look like mine. I have the note 3 running Kit Katt Killer ver 1.:confused:
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] frukyyy:
rvilla1217 if you have the 720T version NAE will not work. I suggest you first flash stock MK5 then OTA NAF will kick in.

NAE is for 720 NAF for 720T

Still have questions about this app for sim unlock do you have to be stock. what baseband/bootloader. if you flash custom rom does it stay unlocked. Does it really work? Some say they can't get calls to work. I would like to test it out on a T-Mobile sim if I know it really will unlock can we get a guide the link to the thread gives no info in the op

The galaxy tools app has a button that takes you to the guide/manual. Basically it takes you to this url (online manual) http://www.androidpit.com/usb-otg-what-it-means-and-how-to-use-it

As far as whether it works on non stock roms, I don't know. Idone (the developer) is very responsive. It's a great question. Just pop it on his xda thread, and he will answer quickly. Then let us know, if you would please.

I'm looking for some help unlocking my [stock rooted] 720T...

I've searched endlessly for close to a week and think (hope like hell) I've finally found all the answers but I just need to know what exactly to do now...

so far I've downloaded the SSU.apk file & MK5 modem as well as Galaxy Tools & APN Unlocker apps...I also have a pre-paid T-Mobile SIM I'm ready to use...

here's where I'm stuck at:

I read in a few posts that I should NOT downgrade the current modem (NG5) to MK5 because of "Knox"...I should tell you my S4 is currently turned off by Sprint (no service/not sure if Knox matters now from what I read already)...

when I opened Galaxy Tools I saw the *SIM UICC Unlock* & pressed that and where it previously said "locked" it now says "unlocked" but I'm pretty sure it couldn't be that simple...

so what I'm asking, for anyone who has succeded in unlocking their 720T, is ***WHAT EXACTLY DO I NEED TO DO IN ORDER TO UNLOCK THE PHONE***??

which steps do I need to take to be able to unlock this phone & use the T-mobile SIM card?

P.S.---

bthorne my friend,

I assume BL = bootloader but not clear to me what you are trying teach us. Also what is AP, and what is CP?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bthorne79:
When Odin changed the original slots from pit, bootloader , PDA , phone

The new slots names are BL=bootloader

PDA=AP

Phone=CP
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
According to the tutorial the slots are now:

BOOTLOADER

PDA

PHONE

CSC

and sorry I still don't understand what AP and CP stands for or what they are.

I appreciate you helping me understand. I am not doing any flashing but I am updating the op with some of these ODIN quick tips.

(not the regular 720) please tell me if these are the steps to take in the correct order:

1-root phone

2-downgrade modem to MK5

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
I noticed (on a pic you posted on the other unlock thread) that you put the modem file in the ap slot in odin. From what I have learned, modems go in the cp slot, which means you had the modem file in the wrong slot. That may be why you are bricking. Let me know if this helped.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] broad_st_bully:
Thanks! I had a feeling that might be the issue....

would you know if the phone is saying "invalid Sim Card" because the modem hasn't been downgraded?

or could it just be a bad Sim? it's brand new with the "unlimited everything" monthly plan......
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] BradGrenz:
Doing the domestic unlock requires both a downgraded modem and changing the GCF settings in the service menu. Directions are found in the SSU.apk thread and linked in the OR here.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Anunak:
So after successful domestic unlock can we reflash NG5(newer) modem? like people do in L720 topic
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
There is no .tar file inside. There is only a modem.bin file inside the zip. Please explain.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] BradGrenz:
Sorry, I just double checked the zip file I used and it is a bin file, not a tar.md5 for the modem. Odin will flash the bin from the cp slot. I'll go back and edit my original post.

720T *confirmed* unlocked & working on T-Mobile SIM (see images)...

it took a few days (and 27 headaches) but I finally got this thing unlocked & working...text & calls work now just to get the internet working...

anybody having issues downgrading the modem to MK5 here's how I got it working:

1-take the Sprint Sim out & turn off the phone

2-turn on phone in download/Odin mode

3-flash the modem.bin file via Odin & wait until you see the green "pass" in Odin & it reboots

4-turn the phone off & insert new Sim & reboot

5-Add new APN for whichever carrier you plan to use

6-turn on then off "airplane mode" & reboot

your phone should now work....

thos are the steps I took to get my 720T working on T-Mobile...you might have to try a different combo but I can confirm this worked for me...

Ok so I used bthorne's stock ng5 as a base and just debloated it like I have for my other S4 L720 non spark and when I do a clean flash everything is good except wifi will not turn on...any ideas?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Learned something on vacation. Apparently native hotspot is designed to shut off when data roaming, even though I have full unlimited data service even on roaming. I guess sprint wants to minimize data roaming usage even if you have unlimited roaming.

Wifi tether router still works even when data roaming. Nice to have as a backup. Just need to remember to reboot before using native again. As a reminder, native hotspot will fail 100% of the time if I have launched wifi tether router previously until I reboot. As long as I have never started wifi tether router since the last reboot, native works flawlessly unless I'm data roaming.

I hope I wrote that clearly for everyone. It's tuff to put into words.

What baseband you on i was not able to get WiFi on NC6 with the NG5 based rom
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] onelovekir:

When I updated my modem to ng5 I was good

yeah still a no go...gonna try just your stock one and see if that works
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] onelovekir:
so I tried just the plain stock rom and still no wifi, my baseband is showing as NG5 so i'm not sure whats going on. When i nandroid back to my carbon rom that I had before, everything is fine. I'm going to try and change back to NC6 modem and then nandroid back to carbon rom, then while on carbon rom change the modem to NG5 and then do a clean flash back to the stock rom cuz after that i'm all out of ideas.

Edit: does anyone have the cf-auto-root sph720T file? chainfire's website bandwidth limit has been exceeded...thanks!

2nd Edit: ok so I downgraded the baseband back to NC6 modem and then installed bthorne's stock NC6 deodexed rom and everything is working fine so far with wifi working. Now I will try and update the modem to NG5 and then install the stock NG5 rom...hopefully that works.

3rd Edit: ok now I'm back to square one...that didn't work. as a last resort I will odin the official stock NC6 rom from sammobile and then re-root, install recovery, upgrade modem, then install rom. Now i just need the cf-auto-root file cuz i deleted my old one...anyone?

Is anyone able to help me recover my phone? Was rooted, running cm12, used mobile Odin to flash a file as I didn't have access to a computer. It restarted my phone and was stuck at loading recovery. I then rebooted and I could not access recovery nor could I boot normally. I tried Odin the mk5 from Samsung and it failed. I then connect my phone to kies hoping that would help and now my phone won't even give me the option to boot Into recovery. It also goes straight to Odin mode and says "firmware upgrade encountered an issue. Please select recovery mode I. Kies and try again " problem is my phone won't connect to Kies in download mode to even try to fix it. Anyone have any ideas how to fix this ? As far as upgrades, I never changed the stock firmware I simply rooted and ran aosp from there on out. I'm downloading nc6 to try that and then ng5.

i didn't think about mobile Odin being the culprit for the brick. The reason i say that is because the mobile Odin has support for the l720 but now that i look not the l720t. Although the file I tried to flash in mobile Odin was for the l720t. I'm wondering if mobile Odin deleted the recovery or tried to replace the twrp with stock recovery for the l720??

Never mind. I fixed the problem. Lost everything and was stuck in kies/Odin mode. I renamed the tar file and remove the .md5 from the end. I also killed all kies applications running in the background on the pc. I believe that is what was causing Odin to fail. Kies interfering with odin it was either that or else kies had to take over odin and be stuck in kies mode in order for odin to work although don't quote me on this. Anyways I'm up and running again. If anyone needs help In the future and loses recovery and is stuck in kies/Odin mode I'd do the things I did.
