Galaxy S5 Stuck On Splash Screen with Set Warranty Bit: kernel ---please help

First post, So hey everyone
So I rooted my phone around 6 months ago with CF Auto Root, everything went fine but i was still on stock ROM. So then i found the Alliance ROM and decided to flash that because it looked cool. I flashed it using FlashFire to ensure I keep root. Everything worked and booted just fine, really smooth and of course it looked awesome. One small problem though, I could not send messages but I could receive them. Probably a SMSC (that was around 3 hours of head ache attempting to fix that) issue or because Straight Talk didn't like my phone using Android 5.0. So then I tried downgrading to Alliance 4.4.2, NOPE. That was the end of my phone :'(
Im now stuck on the Galaxy S5 screen with "Set Warranty Bit: Kernel" in the top right. No idea how to fix it and obviously knox was tripped but that isnt a huge deal to me.
I have tried the following.
1. Tried to reroot (seemed to fix a lot of issues actually)
2. Tried to reflash Alliance ROM android 5.0
3. Multiple cache and system wipes.
4. Installed TWRP through Odin but thats useless because I was dumb and deleted my back up in the system wipe
Im currently downloading stock ROM but my hope for that is fading judging that TWRP even stalls out and the phone reboots right when it attempts to flash. - well this was a bust, there are 4 freaking md5 files. when i go to flash with odin it says it a modem and then fails
What i have access to:
1. Recovery
2. Download
Is my phone already 6ft under or is it hanging on for dear life?
Edit: Should also mention that my galaxy is a SM-G902L (Straight Talks' model???). CF Auto Root for Galaxy SM-900F was used to root. So that is what i based my choice for model when installing Alliance
Ok so recent update, When I go into reboot and do system or whatever, it says there's no OS installed. I guess that would make sense why it doesn't want to boot, because there's nothing to boot into... but why cant i install any OS through odin???
Another Update: So I have no OS, I know how to flash a new OS, such as a custom ROM, but my phone refuses to accept the flash whether through odin or through TWRP.... W.T.F. Did i really look my phone down? And I guess that means that I will need to get the Straight Talk variant of Android 4.4.2 Great If anyone has the a backup and they are on straight talk, please help me out
Thanks for the help!

FIXED!!!
So after around 14-16 total hours of headaches, I have managed to bring my phone out of the grave. I read over the Straight Talk Variant Galaxy S5 thread multiple times and saw people saying that most Verizon ROMs work decently if not perfectly fine with the SM-G902L. So I downloaded M.O.A.R ROM and flashed through TWRP.
Worked like a freaking charm!! She booted right up, into the waterspout boot animation, and after a very long 5 minutes, I got to the welcome and setup screens!! I guess it was just a matter of finding the right ROM. I just find it kind of weird that it would flash Alliance just fine and then not allow it the second time...
Anyway, the very helpful thread that saved my phone

S6 Edge+ G928F dead? NEED HELP!

[My phone is already repaired by Samsung under warranty, my internal storage was broken so they replaced the motherboard. There is no need to reply to this thread anymore. Thanks anyway]
Hello everyone, I need help!!!!
Today my Samsung GS6 Edge+ died. (At least, that's what I think)
I own my G928F for 1,5 years now. I rooted it two weeks after that. Several weeks ago I flashed a new ROM called N-Lite Nougat v4.1 which has worked smoothly and without any problems since I've flashed it.
However, today, the 26th of June, my phone turned off all of a sudden while scrolling through Facebook. I haven't flashed, installed nor done, anything that would affect my phone in such a way that it would crash this way. I tried force rebooting with the 3 buttons pressed (Home, Vol+, On/Off) several times. My phone just boots into the ROM and then freezes instantly. Again tried force rebooting for like 5 times, NO luck. Then I tried booting into recovery mode (TWRP 3.1.0.0), cleared Dalvik and cache, factory reset, rebooted, still no luck. Tried several other custom ROM's, still NO luck. Also tried flashing stock Samsung Firmware using ODIN, no luck whatsoever.
I couldn't find any similar problems in the ROM thread, nor anywhere else on the internet. Besides that, I'm starting to think this problem is a defect to the hardware, not the software.
Does anyone know what would be the best thing to do in my situation? Or perhaps anyone who might know what the problem might be and have a possible solution?
Thanks in Advance.

Recovery mode (TWRP 3.1.0.0) is accessible though, but that's all. While trying to install another ROM it just reboots randomly, during flashing progress.

When you say you tried flashing stock rom with ODIN, does it fail or does it succeed but freezes up when you are back in android OS?

It succeeds. But when it's done it just keeps going in a bootloop. It doesn't even boot into Android now. I've used the right settings in Odin. Even tried several different versions of Odin. No success

Out of curiosity, when you flashed the stock Rom was it 6.0.1 or 7.0?
Does it just get stuck on the S6 EDGE + screen for a while? If so you might be to impatient as first boot on almost all roms both custom or stock take a while to boot up. If it shows the Samsung splash screen over and over then yes it's bootlooping.
I can't think of any other reason for it bootlooping, especially if you have flashed a stock Rom, unless maybe you flashed 7.0 rom and still have a 6.0.1 bootloader. But I think that just causes loss of baseband, not a bootloop.
I would suggest another kernel, but that is normally included in the stock rom.
Do you download them from sammobile or another site? If it's another site, is it a reliable site?

It was Android 7.0. I downloaded it from Sammobile. I've waited 40 minutes for it to boot up after successful Odin flash. But it just kept doing the same thing. The bootloader that was installed was a 7.0 bootloader. First i get the Samsung Galaxy S6 Edge + screen then the Samsung boot animation and it repeats for hours untill battery runs out haha

The last thing I can think of was did you get the right rom for your phone? 928F or 928T etc.
Other than that it might be a trip to the repair centre I'm afraid.

Try to do a factory reset in the stock recovery. It might help.

Yeah i got the right rom for my phone. I've already sent it to a certified Samsung repair centre, it's still under warranty. Thanks for the help anyway

Set warranity bit kernal, couldn't find a fix.

So i i wanted to install a clean rom on my note 3 and got this a message when phone is booting.
thats how it started:
-Installed Odin , then installed TWRP then SuperSu with TWRP.
- Downloaded the LineageOS for note 3 and GAPPS, insalled it and it wasnt stable at all
Had every few minutes restarts with the message "Set warranity bit kernal" at top of the screen.
- Decided to try other rom(MagMa NX s8) , so i download older TWRP for this , installed the rom properly and then reboot
and its got stuck into this message again "Set warranity bit kernal" and didn't boot into the rom at all..
I wanted to try this ROM so hard heh..
- Now im with Resurrection REMIX which is stable and no restarts or bugs, but the message is still there when the phone is booting up.
tried so many things to fix it , could find away tried different kernals, didn't help , tried YouTube guides - none worked for me.
anyone is familiar with this issue?

thats not an issue. Its normal if you had flashed a custom ROM. I am running RRN only for the past 4 months... that message has always been there for long time.

Samsung Note 4 N910F is not stuck in bootloop, still doesn't really boot

Hey everyone,
I have been looking around online for several days now, but haven't been able to find a description of the problem I have with my n910f nor a solution.
When I got the phone it was stuck in bootloops and so I though it was soft bricked.
After I installed the custom rom and the latest version of TWRP via Odin, I thought that the problem was fixed, because the phone booted and I was able to start the configuration of Android (where it asks you for language, time zone etc.)
However, the phone turned itself off during this process. So I wiped everything and tried again, the same thing happened.
I then flashed it with Lineage, but it would turn itself off even before the logo appeared.
Then I flashed it with Ressurrection ROM, but again, the phone turns itself off during booting.
I can access download and recovery mode without any problems, I can flash roms and Odin works like a charm. I also used 2 different batteries.
Does anyone has an idea what I could try? Could it be the version of TWRP I am using (3.0.2.0)? Or is it a hardware issue?
Thank you!!

Hi, I have this exact same issue with my N910T and so far haven't found a solution to this. I really love my Note 4 so I'd like to know if this issue can be solved or not. I event went to a supposed repair shop and they couldn't figure out the problem, guess they weren't that good.

Sorry to hear this.
I have found issues that seemed similar, but not quite the same, and people hinted that it could be a worn out motherboard that is causing this top happen. But before I open up the phone (at the potential risk of breaking at least the screen) I would try everything else.
Or is there a way to test whether the motherboard is defective?

Its the plague of overheated, worn out emmc memories, sadly. Once it happen,the only way is a new/used motherboard,prefferably C model.

eMMC failure, snapdragon models are susceptible to this.

I suggest flashing stock rom with Odin after wiping your whole device in TWRP. I've had the same thing about 2 months ago.

Hey,
thank you for your responses. Yes, I read a lot about it being a motherboard problem.
I got it to work now thanks to this post: https://forum.xda-developers.com/note-4/general/downgrade-official-mm-to-kitkat-t3383885
First nothing happened, but after I flashed Modem and the original Bootloader again (after installing the rom) the phone turned on and I was able to use it for a while (20mins maybe). Then suddenly it turned itself off and stayed on the "Samsung Galaxy" screen for a long time.
Apparently a lot of people are using Wakelock and it seems to be working for some of them, but that seems to defy the point somehow.

Which Stock Rom did you use exactly? Is your phone working fine?

J5 weird flashing problem twrp

Hi. I’ve got a customer with a j5 that I factory reset as she was having problems with it. But now it will only boot to TWRP which must have been installed before she bought it.
I’ve tried sourcing a stock android but with no luck so I tried a few Roms from here today. I can’t get it to work at all! Here’s what Happens.
From twrp I install CM rom and gapps. When I reboot the phone an orange line appears across the screen followed by the Samsung logo. Then the screen starts fading to green. The screen is in full working order when using twrp.
Does anyone have any ideas?!
Thanks

More than likely that version of twrp is outdated get a .IMG file of twrp version 3.2.1 and flash the image in twrp. Use this https://forum.xda-developers.com/galaxy-j5/development/recovery-samsung-galaxy-j5-t3769408/page5
If that isn't the problem and the problem you have persists than you have either flashed the wrong version file as there is several types of galaxy j5 with different hardware,
Or the bootloader you have on the phone is the wrong version ie. it has marshmallow bootloader and your trying to flash a ROM that only supports lollipop or vice versa. Links for both bootloaders are here

This should fix your issues hope it helped
