[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] JerryGNYC:
Never had to do anything like that, but I've heard (and seen) that using low quality (read this as non-Samsung) USB cables for things like this can cause a failure. And I've had file transfer issues because I tried a cheap cable (it was there...) every now and then.

Are you using a Samsung cable?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] churchey360:
Im pretty sure you have to downgrade it to unlock it.

hey folks, sorry for the long post.

I've had my phone for a while now and haven't kept up with updates since mf9. I'd like to restart from scratch again but don't want to update too much in fear of losing any capabilities. when I initially rooted I stayed with a stock rooted version since at the time I was looking for stability and knew I wouldn't be able to be running updates. even though I can be quite a flashaholic. I've been on the wagon and not sure how to return. any suggestions on which rom's are stable enough for daily use? any info the xda family could provide would be much appreciated.

Sprint galaxy s4 sph 720

I have a sprint samsung galaxy s4 sph-720. My son tried to unlock it.then when booting up i keep getting yellow triangle with message that says something went wrong. I got it to boot into download mode. And downloaded what i thought was stock firmware and it seemed to work but now have no volume... I can press volume button and see volume but get no volume, the wifi does not work, cant turn it on and the camera does not work either talked to sprint via text and after some trouble shooting she said to have it reflashed at any best buy. They did not even know what i was talking about.. What i want to do is reflash to what it was like when new then maybe root it and unlock it.does anyone know how to help me, i am fairly new at this so talk in laymens terms. I have flashed custom roms on other phones and dare i say it unlocked a couple of iphones. Any help would be awesome. Thanks in advance.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] cruise350:
This usually happens when your firmware flash did not complete all the way, in other words, you may have gotten most of the install, but the modem or baseband or some other small piece may not have installed. What is your software version? MF9, MK2, NAE, NG2?? I don't believe you can unlock it unless you are on MF9 or older. You may just need to flash the stock TAR file again to fix your problem. It is important to remember, that the bootloader will prevent you from flashing older software on a phone that has been updated. if you have already gone to 4.4.2 you won't be able to go back to 4.3 or 4.2, etc. using odin and official stock TAR files.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
How would you go about saving a rom once you have rooted so you can flash it via recocery, other than a nandroid backup?

I want a stock l720t rom rooted to start with so I can replace some files and test out once I'm done, flashing the finished rom in recovery.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
Yep that works good. I replied on the post. Hopefully if I can pull it off we'll have an s5 rom before to long. I pulled the priv-app and app folders out of this s5 rom I am currently on. Hopefully it doesn't require to much file editing at all and I can just move the files over and write over them.

Probably not that easy but we'll soon see how it goes. I'm not much of a programmer or Linux guru so it may fail miserably right out of the gate.

Well looks like it's more involved than that so I'll have to leave it to someone else who is more knowlegable about this stuff than I am.

If anyone feels like taking this on I have a rom that can be used as a base but is for verizon, but does work on this phone except for gps. If gps worked I'd use this rom. Anyways I hoping someone will pick it up.

Actually, you want to make sure to format the card to Fat32. 64gb cards generally come formatted to ExFat, which causes issues because some roms / kernels aren't compatible with ExFat cards. Windows 7 won't let you format a card to Fat32 natively since ExFat is a proprietary Microsoft format, but you can track down a free utility that'll do it for you.

Got a problem here. I use Swype and I set it as default and it keeps switching back to android keyboard. I've tried freezing android keyboard with titanium backup and it still tries to switch back to the stock keyboard. Is there a work around available?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Salil999:
I think you can clear the cache or data for the keyboards and then do a reboot. That might fix it.

What should you always wipe/format before installing a custom ROM in TWRP? and how many times?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Salil999:
In TWRP, when you load it up, there is an option called "Wipe". It will usually prompt you to do a regular wipe that most people do for custom ROMs. If you go deeper than that, it will show the rest of its option.

Specifically, for custom ROMs, you're supposed to wipe the cache, dalvik cache, and do a factory reset/wipe data. Those options should be there.

As for how many times, I do it once before flashing the new ROM and once after flashing the new ROM, just to be on the safe side.

But make sure you HAVE to do that, though. Some ROMs don't need too, like if you're upgrading from a previous version of that ROM. (like for upgrading a CyanogenMod nightly, you don't need to wipe anything. It will upgrade it without losing any data)
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] baydude:
so you Factory Reset before flashing custom ROM and then after again?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Salil999:
I do it just to be safe, but it doesn't have to be like that. The official method is just:

Wipe cahce

Wipe dalvik

Factory reset/wipe data

Flash ROM

Flash GAPPS (this might not be necessary, depending on the ROM)

Reboot

Profit

I am trying to do a NANDROID backup on TWRP 2.5.0.2 and 2.6.0.0. It says my Data partition is 1989309MB. I have 50952MB (50gb) free on my Micro SDcard.

I'm getting an error saying that I don't have enough disk space to backup all partitions. How is it possible that the Data partition is 1989GB?? Is this a bug? How do I do a NANDROID backup to my microsd card?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Salil999:
How can you do a nandroid backup on both those versions? You either have 2.5.0.2 or 2.6.0.0

And yeah... 1.9 TB is a bit too much for a phone, haha. Not sure what you did to get that. I would probably recommend reinstalling TWRP or switching to another recovery. That is very odd.

And to backup to the external SD card, there is an option in TWRP (from what I remember) that lets you do that. I personally use CWM, so I'm not an expert in TWRP, but I'm almost certain that TWRP will let you backup to the external SD card through the backup menu.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] baydude:
I had 2.5.0.2 installed and it had that 1.9TB bug so I updated to 2.6.0.0 and it still had the same problem. I will try CMW.

Installed Titanium Backup & Pro Key (already had them for my EVO 4G)

I then run Ti Backup & it's stuck at "Asking for root rights..."

At this stage I'm guessing I don't have root.

That's odd, especially if the root installed successfully the first time. I guess you can re-root it using this.

But I have heard of some random MF9 root issues, so I'm not totally sure. But check out that link above.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] StoneRyno:
For about a month now I've had a notification sitting letting me know there is an OTA update downloaded for me and ready to install. I have not bothered applying the update. The last time I updated to NAE the OTA update went bad and I had to take it to sprint for them to flash it after wiping it clean. I had thought I performed a backup of all my data. To my dismay to find out that backup apps only backup data if you are rooted. Both lucky and unlucky that the only real loss I had was 3 years of auto fuel and maintenance logs for my car. Enough of a loss to make me reluctant to want to do anything with updates or rooting or anything else that could put me in the same scenario again. NAE is working fine, but I assume there was an update for a reason and that ultimately I probably should have this update. I've had my S4 for about 1.5 years now. And haven't rooted it since they added all that knox stuff that began the whole you have flashed custom stuff flag. I still wish I had known about that before I had updated from the previous version. But that is meaningless now since the damage so to speak is done and I am stuck with the they will know if I have tampered with my phone or not if that matters any more at this point. I also still have the equipment protection and have been considering discontinuing it as well due to the age of the device and the cost vs reward ratio of keeping the protection. The only thing I used root for that I was aware of in the past was adjusting minfree so that things ran smoother. By default android seems to let RAM get and stay pretty clogged until after you have exited a heavy RAM use app that was performing poorly due to the clog; freeing up the RAM after I have stopped using the app so that it could have ran better had it freed the RAM up when the apps use began is when it should be freeing the RAM. And the other use I now know is for 100% complete backups; I even stated my dismay to the backup app developer of what is the point of a backup app for not rooted devices if it doesn't really backup anything. After all the personal data stored by apps and other personal data is the important stuff. Kind of pointless if a backup app doesn't (can't) back that up for not rooted devices. So I guess my questions are as follows: Are there any concerns I should have going ahead with this OTA? Last time I rooted I followed QBking video. But that video is far out of date now with several OTAs since it was made. So I figure if I root I need updated tutorial to follow to do so. Should I root again, if so what is the procedure for this latest OTA? Other than that my concerns are with any personal data loss that could occur that I'm not aware of if something were to go wrong with either of these things and I end up needing to wipe and have sprint store flash again for me.

1.) Not Entirely True.... Which is what brings me here.

[MENTION=5026910]jaybhatia999[/MENTION] and [MENTION=2696307]JerryGNYC[/MENTION], as a starting point check out the Guide at this link: http://xdaforums.com/showthread.php?t=2415587

NOW, I've used this guide and actually my phone currently works on GSM international network, without going through Sprint for Unlock exceptthat my audio and microphone no longer function.

Full story:

Flashed to MDC easily enough, following the tutorial steps.

Experienced some difficulties flashing back to MF9, especially using links provided in the tutorial (could not ever get them to stick: ODIN kept returning FAIL).

WiFi stopped functioning, couldn't make calls, and camera stopped working. Decided to switch from Stock to Cyanogenmod to see if it would help.

Used CWM, installed Cyanogenmod 10

WiFi worked again, Camera worked again, pretty much everything functioning normally, except:

Can't make calls, watch videos, do anything that produces or receives audio.

If I try to listen to music, I get errors saying the program is ending, and usually also saying DSP sound manager has stopped

Decided to try upgrading, upgraded to (currently running) 11-20141013-NIGHTLY-jflte

Android 4.4.4

Baseband: L720PUEMJA

Kernel version

3.4.104-Cyanogenmod-g52b4b50

build02@cyanogenmod #1

Still can't listen to music, make calls, watch videos, record audio notes, use soundhound/shazam, the list goes on.

Basically, from what I can tell, the software just has no way to access the microphone and/or speakers, and won't allow me to do anything with the phone that uses them. I should add that everything else functions normally: SMS, internet, everything, all function as normal even on a GSM SIM card that I am now using in the phone.

Anyone have any ideas of how I can restore audio functionality to my phone? Obviously I know I did something along the way that affected this, but I'm not sure if it's with the modem, software, etc... Any and all help will be appreciated. If you need any more information I'm happy to provide it.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] cruise350:
if you read the original post, it was about the 720T which it can't be done yet. Now you sound like you accomplished something here but sounds like you f'd up your phone. You shouldn't be using firmware that was for the 720 on the 720T unless you want your phone to behave like yours. I would recommend you odin the latest software for your phone if you want to use it as a phone again and have some audio.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] duckgrits14:
Ahhh okay, thanks for pointing that out, [MENTION=5026910]jaybhatia999[/MENTION] I believe then that it has not yet been accomplished. Best of luck!

I have indeed f'd up my phone... At this point I'm pretty much planning to odin latest software onto the phone, like you've suggested - The only thing keeping me from doing so is that I'd like it to still work on GSM. Do you think I'm going to re-carrier lock my phone by flashing back to stock? Or is that a semi-permanent change that should stick with the phone through the multiple softwares?

So I have an L720t on rooted NG5 software.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
If I'm not mistaken nae is like the att, to or Verizon branded phone. To be honest from what I've tested this past month, there are very few roms that work correctly on the t variant of this phone. Tw roms are slim and none, aosp type there are a few but it's still limited.

After about 20 or so flashes and reflashes, many downloads an installations and resets for almost a month, I finally gave up. I'm going with stock rooted and xposed mods, a modified s5 secsettings and a buildprop tweak for s5 quocktoggles.

When I say not working I mean fully working. I am very picky when it comes to a rom so I test everything major with a rom.....gps, camera, data, wifi, settings, quicktoggles, messaging, and phone calls. If one does not work I search again for another rom.

I found a few gps did not work correctly if at all.

If you want tw, sacs rom is pretty solid I just didn't like the custom battery and could not find one in 3minit mod. But the rom works well from what I could tell.

Some roms had fading data.....It would lose data and come back on again intermittently.

Jfltespr cm11 works ok too

Anyways I don't wanna seem like I am plugging any roms because I didn't prefer any of them for one reason or another.....to picky I guess, that's why I went stock rooted with xposed mods. I've seen a few others that chose the save route as I did simply because this phone doesn't get support like others do.

Hope this helps
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] jtsrtr13:
Thanks for the info. I flashed a CM11 and AOKP rom. Decided to go back to stock rooted because the stock camera is much better than the Google one included in those ROMs.

So Xposed framework installer would be my best bet for stock mods is what I'm getting. Now to install that!

One more question: is it possible to install the stock s4 camera on say....A cm11 rom? I just install it to /system/apps correct?

Will galaxy s4 running stock get ota updates if knox is tripped?

I have a sprint galaxy s4 that I did some experimenting (flashed custom kernal, bricked, flashed back to stock) and tripped knox. I am now on stock NG5 and not rooted (yet). I was doing some research about knox and read that once knox is tripped you will not be able to update to any knox enabled firmware, even via odin. Does this mean I will not be able to get any ota updates (4.4.4 or lollipop)?

Note: When I flashed back to stock, I flashed to NC6 and am now am on NG5 so I hope that means I can get updates.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] JerryGNYC:
You will get OTA updates if you've tripped Knox, but not if you're rooted, or removed bloatware, or anything that the OTA updater doesn't like when it goes to verify your phone before install.
