Please help hard bricked l720 4.4.2 NAE - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

I need to unbrick the L720 4.4.2 NAE, I need someone help dump 128 MB of bootloader.
Here command do back up first 128 MB bootloader.
Thanks all guys.
adb shell
su
dd if=/dev/block/mmcblk0 of=/sdcard/backup.bin bs=1048576 count=128

We need more info if you want accurate help. If you're truly bricked meaning phone won't boot normally nor will it boot into recovery or download mode. If you can get into these you are SOFT bricked. And you just have to boot into download mode and Odin NAE tar.

TPS?
Just saw on the OP's signature that he unbricks android phones for a profit on ebay. So im guessing hes trying to get the bootloader to unbrick a device someone else bricked that doesnt know how to unbrick their phone or pay the deposit for a new device through insurance.

ha ha tired hands
TEP.
Also good catch.

The things that you find when you actually use a laptop to access XDA. Haha I'm always on Tapatalk.
I just tried the adb commands on my NAE stock rooted with stock recovery and it gave me an error plus when I booted up my phone it gave me system UI FC's non stop. I thought I was going to have to perform a factory reset on stock recovery (,would have been pissed if I had to). Rebooted phone and all is good now.

Hello!
I had my S4 rooted and nandroid back up. I was trying to install this link:
http://forum.xda-developers.com/showthread.php?t=2316308
I installed it and gapp installed too and rebooted. I got this message appears
"System software not authorized by AT&T has been found on your phone"
upper corner in orange says "kernel Failed"
That means I did something wrong?
I read about odin. Does Stock rom get you back to fully stock?
Thanks
Did you run loki doki? see.your on at&t..locked bootloader and i dont think that rom is autolokied. Boot back into recovery flash ld.and see if it boots.
Yes odin will put your phone back to.stock,been there done that lol.

Ok, I been reading some threads about recovery, I didn't relieze, i was away from s3 so long. I just restored from backup data and it boots into this stuck Samsung screen with custom unlocked logo. Bootloop?
Havent seen that particular screen but yeah sounds like your bootlooped. If.you can three finger back into recovery and have a nandroid i would full wipe then Restore your back up (even though people.say restoring wipes anyway..id wipe.if u.are using twrp do not format data!).if.your still looped you may have to try and odin back to stock.firmware can be found on sammobile.com had to do this the other night due to a bad nandroid..lots of fun lol.

Thank you!:victory:
My heart dropped like fainting ghost after I see the at&t software showed up. I wiped factory reset and goes past the samsung with unlocked logo into at&t boot up like new phone. It took 5 mins to get into welcome screen. All is working.
Now, I begun to wondering why my logo says it bootloader unlocked and I download correct at&t rom is in? I use this causal download from this link:
http://forum.xda-developers.com/showthread.php?t=2297900
I am trying to understand and pick my first rom. Was thinking downloading pure google rom. Had to read again
That mod.will loki your kernel,prolly why it says unlocked. I.have the.canadian. version..unlocked already thank.god lol.
A.simple wipe can work wonders..if you can get into.recovery and have something.to.flash most times your gona be okay.
Glad your back in.business!

Flash another kernel made for your device, or go thru the ODIN thing, your choice. this is for anyone who have that triangle.
Yes, I read some thread and the roms need kernel, without kernel installed which was has leaded me into that warning att screen. I tried again with roms above link with ktoon kernel and made it through. I was probably be dumb. Pardon me, lots to relearn here.
I own iPhone 4s but I went back to android.

You should be able to get rid of that boot screen with the lock on it by using triangle away. http://forum.xda-developers.com/showthread.php?t=1494114

delete em (un-install), junk, are you getting spam and such? Did you install those? Do you have any protection on your device? Just curious.
Thank you

I can't find them to uninstall them just to force stop and unable them. Not getting any spam but I have used 4shared and and downloaded some stuff that didn't work and just download to my storage. No protection for my device. Any suggestions? I haven't had an android since the mytouch on T-Mobile years ago and I'm still new to this.

[Q] Safestrap TWRP Galaxy S4 MF3

I just have a few concerns after "rooting" my MF3 S4. I want to run CM.10 nightly rom, and the only way I can install the CM.10 rom is by the Safestrap TWRP method as a "temporary solution" for locked bootloader because of the OTA update to MF3. Backing up a "Rooted Stocked Rom" right after I flash the "custom recovery" (I know it's not really a real custom recovery), will I be able to "Clean Install" CM10 by wiping everything before installing CM.10? Will the backup be reliable source to recover in the Safestrap TRWP "recovery"??? Thanks for reading and thanks for any help to my question and even possible success stories in advance.

You can't use cm roms, only tw based roms in safestrap.
thanks for the help. is there any Roms similar to CM.10 that will work? and is a back up of the "root stock ROM" reliable to flash if there are any issues?

Closest you can get that I know of is the gpe 4.2.2 rom.

My MF3 S4's recovery is gone. I rooted then tried installing the TWRP Recovery through Goomanager. The phone works, but I can't factory reset it in anyway possible. Is there a way to fix my recovery image when its fine because of Loki? or, is there a way to install the twrp recovery through Goomanager? maybe keep on trying? any experience?

Took mine up to best buy. If your phone says custom status on it use my guide to fix it and you'll be good to go. All they really do is hook up your phone put it in dfu mode and flash the mf3 firmware back to stock takes only like 5-10 mins

Because I didn't set my phone in "download (Odin)" mode, that's why when the worker connected the phone to the Samsung Tool it read "my device is not supported."? Before the worker connects my phone to Samsung Tool, put my phone in "download" mode?
I've went to best buy Samsung to try to reflash, but somehow my "device is not supported" when they connected my phone.

They can manually select your device from the list. It said my device is not supported but the girl at best buy selected the phone att sgh-i337 and than put it in download mode and ran the flash and it was up and running in 10 mins

[Q] unbrick Sprint Galaxy S4 SPH-L720

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.

Bricked my phone, can get recovery but not download mode. Please help me.

I tried to flash a rom and something went wrong because when the phone booted back up it went straight to recovery. It says at the top of my recovery: Android system recovery <3e> LRX21T.G900VVRU1BOA8, if that helps. I tried to get to download mode it simply redirects back to recovery. Please help. I can adb sideload, so is there anything i can sideload that will fix my phone or get me download mode? This is my only phone i really could use some help. Thank you.

You are right! Sorry!
if that doesn't work, you can try getting a usb jig which forces download mode when it's plugged in. I got one a couple of years ago when I had a Galaxy S2, and it has worked on other phones, including my GS5 :
