[Q] unbrick Sprint Galaxy S4 SPH-L720 - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

I installed cyanogenmod & clockworkmod yesterday and it appeared to work fine. But this morning, it was bricked and when I try to boot it up, it quickly flashes the Samsung Galaxy S4 screen and then shuts off again. It does not boot into recovery mode at all, but it does boot into download/odin mode. When i tried to install the stock rom through download/odin mode it kept coming up with fail messages in the odin pc application. I tried multiple versions of odin yet it continued to fail, when I took it to the Sprint store they said there was nothing they could do but have me send it back to Samsung, and since it is rooted with a custom rom Samsung may not honor the warranty. What, if any, are my options for installing a working rom and getting it to at least boot into recovery mode? Thank you.

What Android version Were you on before, I have a feeling you were odining the wrong file.

I was on 4.4.2 before root and I was running cyanogenmod 11 before it, well...

So you will have to Odin the NAE tar.

Um, this is awkward but after many attempts to re-install clockworkmod, so I could boot into recovery mode, it finally, magically, worked! I had to use some mac software and push the file onto my phone through download mode but it somehow worked, thank you for your help but I already have cyanogenmod running again. Thanks again! :victory:

same thing happened to me, ODIN wasn't letting me flash anything, then I realized I accidentally screwed up my bootloader and I found the most updated version that no one had posted on the forums. I still couldn't get my phone to boot (boot loop), so I just took the SIM card out and it booted just fine.... I put the card back in and everything was okay. I don't know wtf happened, but I thought I screwed up my phone the first hour I had it.

will not boot up

I have an AT&T galaxy s4 that will not boot up. I tried to flash the ROM and install SlimBean 4.2.2 build 6. after it was installed and everything, the screen went black and will not show anything. It wont go into recovery mode and vibrates every 5 seconds whenever i power it on. i tried to flash the stock rom using odin, but that didnt work either. somebody please help!
Can you provide a link to exactly what it was you flashed?

i cant post outside links yet, but i used the one off of phone rebel's website. i found the link under "How To Unroot & Unbrick Samsung Galaxy S4 – Return To Stock AT&T, Sprint, T-mobile, Verizon & More!"
Firstly, why would you flash anything off an iOS website? Secondly, I meant a link to what you flashed before it bricked, not after.

i didnt think that it was an iOS site. and im sorry, i thought you meant the other one.
this is the one i tried at first: http://forum.xda-developers.com/showthread.php?t=2292474[url]
You have the US att or Canadian?
i have US AT&T
Update: i found the link for the stock rom under http://forum.xda-developers.com/showthread.php?t=2261573
attempted to flash it using odin, but nothing has changed.
I'm unable to get into recovery mode or boot up the device. I can only go in to download mode. Any attempt to boot up the device or go in to recovery mode results in a blank screen and small vibrations every 5 seconds.
this all started after i attempted to flash SlimBean on to my US AT&T Galaxy S4.
can somebody please help me? im desperate and need assistance!

If you can go to download mode you can Odin back to stock. There's tons of Odin guides. I can't link because I'm on mobile but I'm sure you can search. As long as you have download mode youre not bricked and all is fine. Just be sure to have latest Samsung drivers installed for your PC.

It sounds like you tried to flash a ROM or Kernel that is not intended for the AT&T S4 and bricked your phone (screwed up your partitions). If so, you might want to look into JTag repair services. There is a PIT file available for the 16GB version of the phone but I wouldn't touch it if you don't know what you are doing.
Odin is working fine, and whenever i try to flash it back to stock, odin says that it passed, everythings good, etc. But then when phone reboots, it just stays at that blank screen and keeps vibrating.
And could you refer me to a guide or something on PIT files or JTAG services, please?
Exactly what he did, looks as if he flashed the incorrect kernel.
Odin is the answer.

pull your battery and wait a few seconds. place the battery back in and immediately press the recovery button combo (vol up + home + power. release just the power button when the device vibrates and you see the blue script in the top left corner).
if this gets you into recovery, wipe data and cache. reboot.
In Odin are you using the phone option or the pda option?
Please make sure you follow the Odin instructions exactly to the T.

in Odin im using the PDA option, just like all of the threads and guides said to do.
and i tried the recovery combo a few times, nothing showed up. it just kept vibrating like before

I'm having the exact same problem, seems like I did something similar (i.e. install the wrong kernel). Any help/assistance would greatly be appreciated

You guys need to start providing links to exactly what you flashed. How is anyone supposed to know if it really was a "wrong kernel" or if it was a seemingly correct kernel that people should stay away from?
Edit: sorry, not you HeartAttack; I know you did.

i did earlier. i tried to flash slimbean on to mine (http://forum.xda-developers.com/showthread.php?t=2292474) which is under the AT&T GS4 section, so i thought it wouldve been compatible. i was obviously wrong.
So this is what happened to me:
I flashed the foxhound rom (link) using CWM, (Wipe data, clear cache, & clear delvik cache. It installed perfectly, but because this is not an AT&T rom, I was having wifi issues.
Rather rewiping the data, clearing all caches and reinstalling the rom and then the ktweaker kernel, I just installed the ktweaker kernel (link) that I got off from galaxys4root.com.
This was my first time using this kernel with this rom. Since it was an AOSP rom I uses this kernel because it was also AOSP.
So now I'm stuck in this cycle where my phone vibrates every 3 seconds on a blank screen. I can enter download mode and I have used odin to flash original stock firmware, but I come back to this same issue every time. As OP mentioned, I am also not able to access CWM recovery after holding down keys to enter recovery.
NOTE: I believe every time the phone vibrates (every 3 seconds), the phone itself is rebooting. Therefore I don't have enough time enter recovery.

stuck in a boot loop

need some help guys. im stuck in a bootloop. I used QBKING;s videos to root and install a custom recovery. this all went flawless. I then used his video to get native hotspot working and this is where it began. Upon completion my first boot hung on the sprint boot animation. I pulled the battery and booted into recovery to restore my nandroid that was a stock rooted nandroid i did before the attempt to get hotspot working. now my phone just bootloops at the galaxy s4 screen. How can i get out of this? is my only option to install a custom rom? I am on mk2 and can get into recovery and download mode if this helps.
Ive tried wiping cache, dalvik and doing a factory reset with the same results.
just tried installing a stock rooted deodeked rom also a 4.3 mk2 rom. and im still bootlooping.
can someone send me a link to an unrooted stock 4.3 mk2 tar that i can flash in odin...im having trouble finding it

i just finished the flash through odin...im not sure if it takes a while to boot after the flash, but it appears that i am stuck at the sprint boot animation...any ideas?
edit: just booted to the lock screen and give me an error message saying that "unfortunately the process android.process.acore has stopped" and then it reboots again...this is my new boot loop.
UPDATE: I decided to reflash the stock unrooted .tar again. it went through the boot process and took a long time on the sprint boot animation, but it did continue to boot into android. THANKS...my heart beat and blood pressure are now back to normal. LOL

If you still want to unlock the hotspot, you will find the correct files for the MK2 software in post 337 of the hot spot mod thread in the android development section. If you use a version that doesn't match your current software version you will get another bootloop.

I actually just let the phone sit at the recovery screen and it came back up.
I originally used towel root and rom manager to try and load the cwm software.

Accidentally Formatted Internal Storage

I was careless and accidentally wiped/formatted my internal storage. Now my phone only boots to the first (Samsung) screen then loops. Safestrap won't even load. What are my options? :crying:
Edit 1:
Finally got it to stop looping and made it sit on Samsung Galaxy S5 screen on my computer it is only recognized as a CD Drive.
Edit 2:
Downloaded ADB but can't get it to recognize the phone using adb devices...
Got ADB to work didn't know of the special boot options, but I don't think the ROMs I'm trying to ADB sideload is working since it just boots up to the Samsung Galaxy screen and sits there again.

Going to need your phone model, based off the fact that youre using safestrap though i'll guess att model or verizon model. First things first, boot in to download mode, (voldown+home button+power button) and connext your phone to your computer with the original cable that came with the phone, download odin and your phone's firmware, and flash in odin. You should be back up and running.

Yeah, using Odin V3.09, I plug in my phone in download mode, it works fine, I put the .tar in the AP, it's all set to go, click start, and on one of the files, it fails after 3 seconds, the other it will try to do what it's doing, then it will still fail.
No custom recovery on g900v, you can use safestrap but that's only on KitKat, on L you'll need to flash an older kernel any time you want to use it.
