Hello and thank you for responding!

And yes, I can't link the rom, but there is a thread on this forum which states in the features:

Unified Jflte, (...) and Jfltespr build with auto loki20

The "fix permissions" screen pops up each time I tried installing some form of SuperSU through TWRP. Each time I selected to fix them. Is there another way to access that screen?

I originally used TWRP because I couldn't get CWM to work, but I suppose I could give it a shot. Using CF Auto Root put me back onto stock recovery, which was the first sign that anything I did was actually working. However, when trying to flash or sideload new ROMs on stock, I'm getting the "footer is wrong/ signature verification failed" error.

EDIT:

IT'S ALIIIIIIIIIIVE!!!!!!!

I NEVER TYPE IN CAPS, BUT I AM OVER THE MOON RIGHT NOW! THANK YOU!!!!!

The ROM post said to use TWRP, but using CWM got it to work! It was literally the only thing I had not tried!
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] KFloyd:
I'm only speaking about using TWRP, not sideloading...not using ODIN. Are you using TWRP and are you sure it's installed correctly? When using ODIN to install TWRP, you use PDA mode? See here:

http://xdaforums.com/showthread.php?t=2338919

Be sure you have the correct Samsung drivers.

Fix permissions is under the Advanced menu/button in TWRP. I've had to use that a few times after using my SD card in my PC (windows borks the permissions?) but again, this is likely unrelated.

Are you installing a .zip file or a .md5 or something else?

When you attempt to install, is "Zip file signature verification" checked? Try unchecking it...

Maybe you can provide the step-by-step, including full file names, of what you are doing and we might see what/where something may be going awry?

(I still have no clear idea what the issue could be)

For the record, I'm using CM12 nightly.,flashed via TWRP, without any major issues -> http://xdaforums.com/showthread.php?t=2304936

This link is about NG2. It has the NG2 modem on the 1st pg/OP.

http://xdaforums.com/showthread.php?t=2866864

Thanks for sticking it out with me-- only 2 months have passed! So, I'm not giving up just yet.

To answer your question, I used a firmware from sammobile.com and flashed with Odin 3.10.0 -- it took me out of boot loop.

Titled:

L720VPUFNG2_L720SPTFNG2_SPR

The file size was a pinch over a gig and a half.

Just to recap. I received the phone in boot loop-- I don't know what put it in boot loop.

I researched what to do and downloaded that stock firmware (matched model, carrier and country) from sammobile and flashed the phone with Odin and it appears to be back to stock HOWEVER it won't connect to wifi.

My research indicates I should find the appropriate file to flash (and not use a file for another model SG4).

So, I need the file I will use to flash to get the modem up and running again. My phone's model: SPH-L720[/QUOTE]

Use the link provided. It has the NG2 modem, it is for SPH-L720.

1. Power down your phone completely.

2. Using pc Odin (v1.85 or higher), place the modem tar only in the PDA slot.

3. Manually boot into download mode on the phone. Continue past the warning sign.

4. Plug the phone into pc

5. Make sure your phone is recognized by Odin, and that Force reset and Auto reboot are UNCHECKED.

6. Flash the modem.

7. Once it finished, unplug the phone and manually reboot.

8. If it doesn't stick or fails, try it in the Phone slot. If it still doesn't stick try using another USB port.

*Do NOT UNPLUG your phone while Odin is running* It is SAFE to unplug the phone after Success or Failed.

If it fails/doesn't stick, do the steps again but try it in the Phone slot and/or try using another USB port.

I clicked on the link and was directed to a website called androidfilehost.com and clicked on the grey button for regular download and an exe. file popped up.

I tried both on phone and pc and downloaded the modemonly.tar md5

It will be under the Start Download. Go to where it says Begin Download. It will take a few seconds then it will say> stand by searching for mirrors. Then go to primary dowload or alt download mirror.

Hopefully it will download the modemonly.tar. like I stated above, it downloaded on both pc and phone for me.

I downloaded the tar file and used a sum checker.

*Before I ever posted on here I had updated the Samsung drivers... before flashing the Stock rom to get the phone out of boot

I opened Odin 3.10.0 and loaded the file

I unchecked all the boxes in Odin

I completely turned off the phone (removed the battery)

Booted phone into loading

then plugged the phone in and waited for Odin to recognize it

I hit start and it ran indicating all requests were successful

my phone had a blue bar indicating the download was occurring but froze stating not to disconnect-- since Odin was finished I closed Odin

then unplugged the phone even though it indicated not to disconnect (I waited a long while and auto reboot was unchecked in Odin)

I went into recovery mode and hit reboot

.. nothing happened.

I tried all 4 of my USB ports and tried using both AP and CP to load the tar.

Any other suggestions?

I did used an official samsung USB cord, the one that came with the S4

I couldn't find 1.85 and DL 3.07 instead.

I tried both options (PDA, PHONE) to load the tar and tried all 4 USB ports again to no avail.

After I'm done and get a PASS from Odin and the script box in Odin says "Success" and the phone is frozen with the blue download bar seemingly full, however states do not disconnect source-- I hit exit on Odin disconnect the phone and then hold volume up, home button and power to go to recovery to manual reboot.

Am I missing something?

Sounds like Odin is working..1st thing, do not enter download mode using restart function of phone. Turn phone off using power button and enter download using power and volume buttons. Run Odin, when complete turn phone off, then restart. (Do not restart phone from Odin)
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Elpoep:
I only go into download mode only using the volume buttons. I always power off and remove the battery before entering into download mode manually.

I have NO boxes checked in Odin (Auto Reboot or F. Reset Time or any other button). After Odin is done the phone just hangs with the blue bar apparently filled. I waited and waited and the screen doesnt change-- so I hit Exit on Odin then remove the cords and turn off the phone. I then enter recovery mode using the home button and up volume button and manually reset-- nothing happens.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] 2WhiteWolves:
When Odin is finished, do you see a complete blue line ( I think that is the color) on your phone? Once Odin is done, your phone will not do anything because you unchecked Auto reset and Auto reboot. After Odin says Success, just unplug your phone hold power down till phone shuts off, take battery out, wait till 10 seconds or so, put it back in and try to power up phone.

I don't see a complete yellow line, I see a blue line from beginning to end with no change in color. Odin is the only indicator that the flash is done and each end of the blue line on the phone has an oval shape.

I've tried not going into recovery for manual boot and instead turned off the phone and removed the battery for 10 seconds. The WiFi is still not turning on.

---------- Post added at 08:07 PM ---------- Previous post was at 07:25 PM ----------

I already flashed the phone once to get out of boot loop -- I did it with out confirming I was rooted and I still don't know if I was or am rooted.

I downloaded TWRP. Should I just move ahead and use twrp or do I need to make sure I'm rooted first?

If I need to be rooted first can I just attempt a fresh rooting? If so, can you suggest a tutorial? Only guide that makes sense to me is the motorchopper root as it appears it doesn't require my phone to have internet access.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] JerryGNYC:
IIRC, CF-AutoRoot doesn't require you to be online, it's done with the PC/Odin method. If you have a terminal program on your phone, go into it and type su at the command line. The prompt will change from $ to # if successful (and you may get a request to confirm access). The # prompt indicates root user.

Awesome sir, thanks a mill!

Any help at all will be appreciated. After I try your earlier suggestion I'll get right back at you.

1 question however, if this phone was rooted before I received it...

(the guy who gave me the phone said he attempted to root and the phone got stuck in 2G with no WiFi-- I factory reset and was stuck in boot loop and then flashed a stock rom with Odin to get out of boot loop. now it looks like a regular S4 showing up and down arrow by the 3G indicator in the upper header and the phone will not get wifi)

...would it be ok to do a root procedure on it again?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] JerryGNYC:
Well, from what I know Sammy-wise (sorry JRRT), I'm pretty certain that flashing a stock ROM via Odin will leave you without root. Should not hurt to do it again. Be careful what method you choose, some of them are outdated and can mess up the device badly. If you've got a 720T (emphasis on the "T"), I recommend looking at the first page (minimum) of the thread by [MENTION=5662793]bgmg[/MENTION] - there's lots of great info there.

Sprint S4 problems

Hy all. I bougt unoficially, from somebody i know, a Sprint Galaxy S4, like 2 weeks ago. (Anyway I live in Europe). It has stock rom on it, the first thing i wanted to do was to flash a custom rom. I played with roms and kernels a little bit, but like 2 days ago my phone went completely crazy. At a certain point i wanted to flash the stock rom back with Odin, but never had success, it always failed. (Figured out that it was an older rom, and i needed a newer one to be able to flash). At a point i gave up the idea of the stock rom, so i flashed i think some CM11 Nightly, and Gapps. I don't remember if i changed the CM kernel or not, but I couldn't turn on WiFi. The switch simply gone back to Off as soon as i tried to switch it on. The other thing that disturbed me, that the Youtube app would not play any video. I figured out that there is something wrong with the audio, it couldn't play any sound at all, voice recording didn't work aswell. It could be the reason of the Youtube issue, but the more frustrating thing was that i was not able to hear the other person in a call, and the other person didn't hear me aswell. The complete audio stuff has gone crazy. I couldn't play any music at all aswell. The other thing i figured out, that the camera didn;t work, it simply crashed. I was soooo confused, i made sure that i have the CM kernel, because i had this rom before, and none of theese issues was present. Yesterday i managed to get the stock rom back on, (I explained how), but it was soooo buggy and laggy, but the worst is that the wifi/camera/audio issue was still there :(. then I flashed MIUI5, i used it before, liked it, but it will never be my daily driver. Camera and wifi finally worked, but the audio issue is still present. In addition, the rom doesn't behave as last time it was flashed, i would not say it's laggy, but buggy. After booting, I can't seethe Home screen icons, first i have to swipe down, go to settings, then press the Home button to be able to see the homescreen. CM wasn't the old too. But my biggest problem is the audio stuff, i tried 2 kernels, but none of them fixed it. Is here anybody who had the same problem?

On the top of all theese, i cracked the glass(Thanks GOD, just the glass), I'll fix it tomorrow.

.

Edit: Just reflashed stock rom, and got sound when at Sprint logo, but the phone tuned off due to low battery...damn :D

Now as soon as the rom boots, i get this message: Unfortunately, the process com.android.phone has stopped. If i hit OK. the message disappears then reappears immediately. I am really confused now. Any ideas?

Okay guys, last edit here. After flashing, couldn't get into stock recovery, so i rooted, flashed CWM in hope to be able to do a full reset, but couldn't get into recovery mode. Flashed stock rom again, rooted, flashed cwm, this time it let me in. First booted the phone, same issues. went back to cwm, did a factory reset, cache wipe, dalvik wipe, and voila, everything is working as it should. i'll avoid flashing stock roms in a while :D

How do I flash TWRP

My phone's model: SPH-L720

I downloaded:

openrecovery-twrp-2.8.4.0-jfltespr

I flashed the TWRP with Odin and copied and pasted to my phone:

CWM-SuperSU-v0.99

Sorry, just seen your post, been busy family stuff. Glad you got rooted and custom recovery on. Do you have that NG2 kernel? If so, put it on your phone, the zip folder, go to custom recovery> I always wipe cache/dalvik-cache> then to install zip> go to where you put kernel zip> install it, then I do a wipe again just for good measure and reboot.

You've been extremely generous with your time-- I really appreciate it; don't apologize.

update:

*I didn't put the NG2.zip file on the phone first

I went into TWRP and hit the wipe button and it did a factory reset as well. I realized then I needed to put the NG2kernel file on the phone.

I went back into TWRP. I wiped again, I then installed the kernel, I wiped again and then I rebooted -- still no WiFi.

Where did I go wrong? Or, any suggestions?

Should I retry that NG2-ModemOnly.tar through Odin again?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] 2WhiteWolves:
Yes, try the modem again. When Odin is finished, reboot into TWRP and wipe again.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Elpoep:
No WiFi.

I tried a few different things and I noticed that the phone auto updates 134 items every time after trying to wipe, install the kernel and then wiping again (I'm now only wiping Davik and Cache).

I'm still on NG2 btw, does that have anything to do with it?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] 2WhiteWolves:
Each time you wipe cache/ dalvik-cache it will do that 134 items. Try restarting your phone, then see if wifi will turn on.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Turnkeys:
I was looking for a PIT file, because Odin was reporting it missing. Initially I used Odin 3.07, following QBKing77's video-guide to root. That went well enough. It was the edits to the permission's file that shot me in the foot.

Following a tip further up the thread, I talked a Samsung rep at Best Buy to take a crack at it. Using what he called, Samsung SMART, a non-public proprietary diagnostic tool? (When I asked about it, he said it wasn't public, "Otherwise, would would you need us for?" Seriously???) Would love to get a hold of that app.

He managed to successfully flash a stock ROM, L720VPUFNG2, 4.4.2. But the app crashing issue remained.

Begging your (and anyone elses) pardon for the wall of text, the following post describes the current state perfectly:

I've not done anything with my handset since returning from Best Buy. Though I'm desperate to have a working handset, I'm paranoid of blowing the flash again. Before trying anything further, I want to be absolutely sure.

Attached are pics of the stock recovery and download screen details. The youtube link illustrates the app crashes at startup.

First off, you need to use the correct cf autoroot file when rooting. You used the one for the international S4 and not the Sprint S4. After you get it rooted, don't mess around with the permissions file. Just download sdcard fix from the play store and run it. Bam, full functionality of SD card.
