Did you figure it out with Odin normally its a bad cable if Odin does not see phone or drivers need to be reinstalled
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] thirdcoastraised:
I just had that issue with Odin today, turned out to be a bad data transfer cable, switched it out flashed the NG5 modem back to my phone and just came from Cricket where it was successfully activated still rooted and running well :D

Sent from my SPH-L720T running CM12 because it is possible to experience Triband service on an awesome AOSP ROM

No it's new. It was fine until i did an update i think the update wasn't complete. Cause i have a notification that can't go off says " system update..." i think it has something to do with the unknown baseband. Please help me i can't make calls in viber Skype or anything else this problem is making my phone useless
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Sorry I don't know what else to do. Hopefully someone else on this thread has the answer. My last suggestion would be to take your phone to one of the Samsung experience techs at best buy and see what they can do for you. And if you learn the solution share it here.

Since the update it's NG5 i tried the NC6 with odin and it didn't work the phone can't start so i made it go back to NG5 throught odin and no baseband or IMEI back. I'm

Currently on stock rooted mk5 and am really having difficulties identifying a custom recovery that works constitently. Recoveries often when restored have apps by the dozens stopping unexpectedly. Clearing cache does not solve it, titanium neither. Seems the only fix is (if possible) uninstall and reinstall the app.

What custom recovery can you reccomended that works (verified).

I have tried the last 3-5 versions of TWRP and several of Philz. Perhaps I just need a specific version number :) Hope someone can help, thanks!

Been meaning to post this for a long time. I've noticed on my 720T stock nc6 that the vibration test does not work. My screen goes black the phone does not vibrate... but it's only the test that doesn't work. My vibration works fine everywhere else. If I have my phone set to vibrate and someone calls me my phone vibrates as intended... so it is only the test that doesn't work.

Can someone else try the vibrate module test on there 720T and let me know what happens and what firmware you are on?

Just dial *#0*# on you dial pad, then tap Vibration.

To the best of my knowledge, you need to do this with a stock (TouchWiz) ROM. HTC EVOs work the same way, can't update profile and PRL on an AOSP ROM.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bthorne79:
Nope not on aosp ROMs you can flash one of my stock roots and update that way
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] hllywd:
Hey bthorne79 I'm on your deodexed room and lovin it. But the other day I wanted to update/try another prl and when I did the ##data# thing there was no prl in the menu. I had it before running your rom. Any thoughts?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bthorne79:
Should just be under setting and update

I'm not a touchwiz user it does not stay on my phone
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] hllywd:

Newbie

I'm pretty new to the whole root, recovery, and ROM stuff. I've gotten a far as rooting with Odin and CF auto-root and flashing a recovery (TWRP 2.7.0.1). I was looking to use C-Rom for a custom ROM. I had watched a few videos for the L720T to get to the point I'm at, using ROM installer to download and flash the recovery. The video I watched showed them downloading C-Rom directly from ROM installer and flashing it. But for some reason the download would fail every attempt for me. I then tried going directly to C-Rom.org on my pc to try downloading it and couldn't get to the download page. My question is, does anyone know a different link to download C-Rom? Or does someone have the zip file which they could send to me? (preferably C-Rom kk v6.3 but any will work if it's running well on the L720t. Or if someone has a suggestion on a different one for beginners, I'm all ears) thank you for your help!
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Just for knowledge, I asked idone if Galaxy tools sim unlock will work on 720T. He said "Yes works fine. If the S4 says "SIM uicc NOT SUPPORTED" let it do a system software update and it will be supported. This was the first device to get UICC lock after it was unlocked by cable. So old versions need an update to support it".

I then replied "OK thanks. Typically and if i understand what you meant correctly, a system software update would upgrade the os and require the phone to be rooted again, and the rooting process can be completely different and more complex for the new os version. That being said, do you happen to know what the cutoff is? I'm on NC6. I guess I could just try it and see if it works if there is no negative risk :p"

To which he replied "Oh 100% sure NC6 don't need an update. It will unlock. No neg risk, on phones without Sprint uicc lock it launches perso, enter network unlock code menu. Yes system software update would require you to root again, but an update not needed for your system software version."

So I tried and within about two seconds my sim was unlocked. I have no interest at this time to go to another carrier. I just tried this for others and wanted to share.

Take a look at pic in next post for evidence
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Corrected post. Changed SPR to XAS and added reboot.

Check previous post for story. Notice upper left of pic says sim unlocked.

Also. . If you set the sales code in the upper right to XAS then press set and reboot, it will unlock your APNs and make them editable :) see pic evidence in next post.

I believe it's automatic with the latest version of Galaxy tools from the play store. Check the play store and let me know if you have the latest version.

How to Enable PRL Write Option

I just signed up finally on XDA after years of using this site to greatly help me, and just wanted to say THANK YOU very much! Anyway I thought I would throw my two cents in: I took a chance and flashed the attached .zip and it worked for NG5 build on my SPH-L720T. I now have the "PRL Write" option in the menu. (Dial ##DATA# and choose View) it should be there after you flash it. FYI: I flashed it through TWRP.

*** Just in case always make a Nandroid backup :D ***

I would post the link to the .zip as well but since I just signed up I guess I have to wait until after 10 posts to add an outside URL link.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] JerryGNYC:
The MSL shows right above the SIM UICC status and unlock button (see your screenshots). Checked the Play Store and I have the latest version. If I run the app immediately after a reboot, it will show me my MSL, but only then. Odd... and I just accidentally touch something in Galaxy Tools and rebooted into a Hands-free Activation! ARGH! :eek:
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
I know where the msl appears in Galaxy tools :) hmm...are you stock? I wander if maybe the dissapearing might have anything to do with flashed firmwares.

I also hit a wrong button in Galaxy tools before causing a reactivation. Had to step all the way through it rebooting a few times along the way but it didn't cause much damage. Just had to reapply hotspot mod and some small things like that afterwards.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
[MENTION=2696307]JerryGNYC[/MENTION] before idone added the msl I previously ran SPCUtility.apk which is a msl reader program. I'm not sure if that had any long term affect on the msl continually showing in Galaxy tools.

I would embed the the apk file in this post but this xda developer premium 4 app doesn't seem to have an option for adding attachments.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] JerryGNYC:
I don't think running the other app would change anything. I was able to view and record my MSL so no big deal. Thanks.

MSL Code and SIM UICC Unlock Option disappearing

Just an FYI: It is doing the same for me with GalaxyTools app. When I first turn my phone on my MSL Code is there and I am able to Unlock my SIM but then after about 5 min. those to options say "Unknown" for the MSL and "Not Supported" for the SIM Unlocker. Very strange but I was glad to hear that it wasn't just me. Anyway it did what I wanted it to do, give me Native Hotspot and Add all Notification Toggles. :good:

Edit: When the phone first turns on you can open GalaxyTools app, however, if you exit out of it by using the Back button and then reopen it, it will have those errors I mentioned. Use the Home button to exit out of it and it will continue to run in the background, then whenever you open GalaxyTools back up it will still show your MSL and SIM Unlocker.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
I exited six times using back button then rebooted and started over. I even completely closed the app another six times by hitting home and sliding it off and restarting app. No matter what I do, my msl always shows.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
You are correct that for now there is no real point for me except that I wanted to learn how to unlock my apns and I don't like it when I'm locked out of my own phone features when I paid hundreds of dollars for my own equipment. It just my ocd :p

I also wanted to learn if Galaxy tools sim unlock and apn unlock worked in order to help others on my thread and post the results.

At least on my stock nc6 with towelroot, I can say that I have had no issues for three weeks since I performed the sum unlock and apn unlock. Everything is working perfectly.

Boosting the volume with a MOD or Hack

Hello, just wondering if anyone has figured out how to boost the volume on the L720T? And I don't mean with an app... with my S3 I was able to go into device/etc/snd_soc_msm/snd_soc_msm_2x and change the percent under Speaker in the digital section. According to other threads for the S4 you go to the same place but go under snd_soc_msm_2x_Fusion3 and change it the same way, however, with the Triband model it's not working. Has anyone had any luck with this? Is there a hack or MOD out there that anyone knows of that works with the Triband model (L720T)???

Thanks!!!

Thanks for the reply. I tried flashing the .zip MODS through TWRP and it just gave me an ERROR. The apps they listed don't work either :( I did find a thread on here of a guy who was having the same issue and got a replacement aftermarket speaker off of Ebay for like $5.00 and I watched the video on youtube (sorry can't post links yet) and after he replaced the speaker it made the volume much louder. I just ordered one, I figured WTF it's only $5.00, if it doesn't work then I have a spare. Anyway I will repost when I get it and try it out, it's coming on a "slow boat" from freakin China so I probably won't get it for a month but I'll let ya know. Thanks again!

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] luzfero:
Yeah that is my problem. I'm happy that the unified builds added Credo APNs but every time they have it do the auto activate phone call after a fresh install, it borks my mobile data and I lose the ability to make or receive calls. The only one that doesn't, keeps me in digital roaming all the time. So I'm pretty much stuck using sprint builds.

Oddly enough when I tried CM12, NFC worked in the beginning to transfer my account information (which is way cool) but after that I couldn't get it read any of my NFC tags.

I'm surprised something as small as NFC is being such a pain in my ass.

Why some apks are installing on external by default?

Sorry for getting of topic a bit!

64GB SDCX died for no reason, I didn't lose much since I barely used it. Tried all to recover reformat with no success. SD formaters see the card as only 6GB but cannot format. I gave up on it since it seems that the card is deffective, Anyone had this issue?

Upon my cards failure I realized that some apk's (XDA for example) installed on external sd card instead on the internal.I put new card and I re-installed XDA, again it went straight to external. But when I installed Voice recorder the installation stayed on the internal. Most likely it's a noob question but first time I encounter this behavior. I would greatly appreciate if you explain how this works or if you can point me toward explanation.

Have you tried using this to reformat the card? I've found it to work in situations where other programs dont... -

It's possbile there are scripts in the .apk files that cause them to be configured to use the external SD card. IIRC, an .apk can have scripts that are run upon installation and/or removal.

Thanks for the update. NAE is not the Sprint 720T or this thread. If I understand the rest of your post, it sounds like you are confirming this tether on a Sprint 720T MK5.

Can you confirm some of your tether settings such as "Interface", "Method", etc?
