Huge problem S4 not working anymore..

So this is my sad story..
I bought a second hand Samsung S4 (i337M Telcel) Unlocked, the day i got it, i tested in front of the seller everything was nice and smooth.. So i payed..
I was very excited and i proceed to make the Root proccess, at beginning i was having issues with the drivers and Odin, then i was able to fix it..
Anyways long story short i ended up with the ROOT, CYANOGENMOD CM11, and PHILZ 6.. The first day was working fine my cellphone.. (I must say i rooted in my life at least 4 devices even an S4 i9500 all of then with success and not a single problem.. Using them form months and even gears.. The latest was a Moto E..)
Ok so the i337M was working good since the first morning with the root, but in the afternoon it just turned off one time.. Was weird but i didnt pay much atention..
The second day i was listening music and suddenly it turned off, and since then the cellphone is not able to keep on for more than 10min..
Some times i can load the complete OS and ofter 2 min it turn off sometimes at the Samsung S4 logo turn off something i must say is that the Device every single time i turn it on, on the Samsung S4 screen says "kernel is not seandroid enforcing" in red letters, some people say it happens when the root process is not made correctly some says it normal because its rooted..
I already installed from Odin the Stock ROM from SamMobile, and the problem is exactly the same.. A friend of mine told me it could be the Logic Card AKA Motherboard.. But i want to believe its just a software problem.. Cuz' before i rooted cellphone was working..
- Download mode: Works like a charm not a single problem and basically its the only way i keep trying different options to install on the phone..
- Discovery mode: With CWM sometimes works good, sometimes it just turn off, with Philz runs good not turning off or something and its how i was able to wipe data, cache, dalvik, factory reset to the cellphone..
Im thinking in starting over like pretending i didnt do anything to the cellphone, try again the root, the rom, the PHILZ (dont know how to call it).. and hope for the best..
Any advice or reliable links where i can download the correct files for my S4 i337M.. You are basically the last reliable source i have to fix my S4 if you give up with me, then i must admit my cellphone has passed away ..
Hope you can help me thanks in advance and have an excellent day!!:laugh::good:

The first troubleshooting step (to determine if the issue is hardware or firmware related) is to flash back to stock with Odin. Since you have completed this step and find that the problem is still present, this suggests that it is a hardware problem.
I have seen a custom kernel cause sleep of death, which makes the phone appear to have turned off. But in those cases, flashing the stock kernel fixed the problem.
Perhaps you should see if you can return the phone to the seller for a full refund.

Thanks for your reply.. I still dont know how but with Philz recovery, i was able to make a full wipe, i mean it deletes everything every single folder previously made was erased, and i can tell you that because i have a folder called ROOM where i places my ROM, Kernel, etc.. So i can flash them in discovery..
So i erased everything and then proceeded to install via Odin the Stock Rom and guess what it works like a charm, not a single problem.. So, so far the cellphone is ok.. I tested for two hrs.. Now i tried to install a custom ROM and its doesnt load from the Samsung S4 screen jaja... But im still having acces to discovery and download mode so thats ok..
Just two advices.. Never ever download files from Youtube ****y links.. Always go to the source.. Youtubers are assholes.. Real help and information comes from real people that knows what they are talking about like this forum and also updated and real ROM's come from the main source not Mega o Linkbucks...
Other advice embrace your self to do it.. Study every single question you have in Android, from KERNEL to ROM and ROOT.. Isn't that difficult..
One more question, Which ROM with Lollipop would you suggest to install i have the i337M?

May I make a suggestion? Now that you have the phone working, can you possibly just use it for a week without doing anything to it? Don't try to root it or do anything other than text, make phone calls, and install a few programs. This will establish a baseline of behavior for your device, so you'll be able to tell when its behavior is out of the ordinary.
I understand your desire to make it your own. I got my S4 brand new from AT&T and said that I would wait at least a month before rooting it or changing roms, in case there was a problem and needed to return it. I had good intentions, but I couldn't stand it anymore and rooted it after only 3 days! It will take a lot of patience, but you really need to use it for more than a few hours to make sure that the hardware is okay.

I agree take baby steps, week stock, week root, week recovery. Figure out if its hardware or one of the steps is causing it.

[Q] i9505 Somtimes boot, sometimes doesn't.

I had an S4 in for LCD replacement, everything went fine. Possibly the EASIEST phone repair possible.
The phone was reassembled and worked fine, put it up for sale and updated etc. After a few days of it sitting there I went to turn it back on and it wouldn't boot, just hung at the Samsung logo and wouldn't boot recovery.
I left it and thought i'd sort it the next day and went to proceed to flash with Odin until the battery charge logo came on so I knew it was working and then I turned it on and it all worked fine.
It was working fine so I thought it was a one off so turned it off and it happened again. Now im constantly flashing via Odin to try and get anything out of it, sometimes it will boot up get past the Samsung logo then it will freeze.
I have read near enough every threat on the subject, I doubt I'll get an answer here but I'll keep this bumped everyday in hope there's somebody who knows what's going on.
Here's what I've tried
- Flashed latest rom via odin
- Flashed 4.4.2 via odin (supposed to fix this issue)
- Flashed PIT & latest rom via odin
- Flashed PIT & 4.4.2 via odin
I don't know what else to do

Check hardware.

What hardware...?
I have looked at the logic board and can't find anything wrong with it.

Well, it can't be the software because you already tried a bunch. The only constant thing is the hardware. May be a semi-functional power button. I don't know.

All buttons work fine.
Doesn't look like eMMC is the issue because it's writing to the NAND, there's probably an IC with a bad solder joint which explains why it randomly boots sometimes, the only problem is I don't know which IC it is.

Reflowed U800 IC 140c and i9505 booted up no problems

Hardware or Software Issue? (Diagnostic Needed)

Hello,
I am having issues finding what the problem is on my phone. The problem all started when I rooted and installed a custom rom on my galaxsy s5. It worked perfectly for a couple of months. Then I started noticing this weird issue whenever I plugged in any headphones the phone would automatically restart. I didn't really look into the problem like that and just kept it the way it was, since I used bluetooth alot.
The problem progressed to the point that when it restarted itself it would go into a boot loop. I would have to take out the battery wait a few seconds then plug it back in. At this point I decided to restore back to stock firmware. But this made the problem worse. Now its a 15% chance the phone boots up normally, and 85% chance it boots to a black screen. By black screen I mean it boots up normally but I cannot see anything on the screen. I hear the sounds, and touch still works.
If I am lucky and it boots up normally it works perfectly for a few hours. Then at randomly when I put the phone to sleep it restarts itself. There is no reason I can think is causing this problem.
Phone Info:
Model: G900T 16GB
Firmware: Stock 5.0
Flashed With: Odin 10.x.x
Please help me diagnose my problem so I can fix it.
Possible Hardware Issue:
Digitilizer/LCD : Black screen explains this. But also if I do not put the phone to sleep it will work for days. Boot screen, Download Mode, Recovery all work without problem.
Internal Memory - Could be, that means I have to throw the phone away. But wouldn't nothing also work...

Possible Software Issue:
Corrupt Rom/Cache: Flashed several different kinds of stock rom, all with same result. Used recovery to delete cache.
Virus: Yeah leaning towards this.. Maybe somehow hooked itself to the core aspects of the phone.
Recovery/Download Mode Corrupt: This part of the phone is corrupt. 15% chance of booting to recovery. And Download Mode doesn't delete all user data.

Flash the correct PIT file along with (Same time) as a stock ROM, if the problem persists, hardware is the issue

um.. maybe you are right. Motherboard most likely huh.

You had really serious problem, do you try Initializing via kies3 already?

I will try as a last resort, since 5.1.1 is unrootable. You know whats weird I am not having any issues now. I will let it stay like this until it gives me a problem. As a computer science major this is pissing me the fck off. Not being 100% sure that it is a hardware problem.

N910F problems - emmc read fail/ flashing stock no longer boots the phone.

Hello. I had gotten this Note 4 phone which had a custom recovery installed on it but the rom seemed to be official, on 5.1
The first thing I did was go to samfirmware and flash a 6.0.1 rom, it went fine, phone was working properly. Then I got greedy and wanted to test a Note 7 ported rom. Flashed TWRP recovery and from within I flashed RamROM http://forum.xda-developers.com/note-4/snapdragon-dev/rom-sm-n910g-ramrom-t3400349 , I downloaded the one from post#2 , the N910F one that my phone is and after it flashed to ROM it simply stopped working. My phone no longer booted, was booting me directly into Download mode with emmc read error. I kept trying to flash the stock rom which I previously flashed and it would fail.
Afterwords I used Smart Switch to reinitialize the phone, writing my phones S/N and that failed as well but at least that made my phone boot into a different recovery where it said to connect to Kies. Once again I used Smart Switch and this time it was successful 100%. My phone even booted into the OS and was working, however, while using it, after 10 minutes the phone restarted into Download mode with emmc read error.
So all in all the phone is functional but it starts to lag and restart. Now I'm kinda stuck again since I've tried to flash the firmware I got from Samfirmware through Odin, it succeded but it just doesn't boot, it goes to Recovery, tries to apply an update and I get an error.
Is there anything I can do? I can't believe the emmc could've broken just from trying to flash that custom rom, especially that afterwards I was even able to boot into the phone.
Thanks for reading and I appreciate the help.

read this - http://forum.xda-developers.com/note-4/help/note-4-issues-t3453048
there are links to more threads related to your issue.
Short version though:
it is dying. install wake lock application, add it to start up and set settings to #4.
accept the fact that your phone will eat the battery faster and one day WILL die completely

Thanks for your response. Regarding the Wake lock application, I'm starting to look into it, I asume I'll have to be rooted. I'll try to recover it again using Smart Switch and then I can only hope I can install TWRP and still have it functional.
Previously when I was able to get it working with Smart Switch, entering the recovery messed everything up. It said it was applying an update and that got stuck.

no need to be rooted, just download, install and set it to autostart

I'll try it if I somehow manage to get the phone working again, Smart Switch just fails now midway through.

Is this the app you're talking about? https://play.google.com/store/apps/details?id=eu.thedarken.wl&hl=en
What exactly does it do?
I managed to restore it eventually with Smart Switch, it took quite a few tries, then I switched to my Macbook when I saw the app was available on it too and the 3rd try succeded. I only did it because I saw the 2nd try had the % much higher than the first.

yes, that is the app.
i've read it does not allow your phone to go to sleep mode.
drains the battery faster, but this is the only way to keep note 4 working without swapping its motherboard...

I have a question, my gf recently bought a note 4 and we may swap our phones and if we do, i'll flash CM and tinker with it because i find this phone very interesting, just a question, does this bug affect the N910C (exynos) model? Do i have something to worry about? Because the phone is warrianty protected and if it's the case, i don't want to break it. I hope someone will shed some light on this

my S7 edge is hard bricked

I had BlackDiamond.N8.PIE.V2.0 over a year on my phone and it was working with no problem.
today I decided to update my phone, first updated the TWRP to the latest version "TWRP-3.4.0-0-hero2lte" updated without any problem,
then I downloaded BlackDiamond N8 Port V10.0, wiped everything (even internal storage), and installed the ROM,
it installed successfully, wiped the caches, reboot to the system, android loaded without any issue,
after loading into android, I added my google account, and I was testing the phone, after 10min of working with the phone,
while I was testing the camera app (it's was a little laggy) my phone freezes and after a couple of seconds, the screen went black! I thought it's gonna reboot, but nothing happened.
I tried to hard reset the phone by pressing "power+volume down+home key", but it didn't work, connecting to the charger is nothing happen, there is no LED light, my phone is completely dead
does anyone have any idea why this happened? installation and booting to android was completely fine, everything worked fine, and suddenly my phone freeze and hard bricked.
you know this is not the first time I'm installing custom ROM, I'm done it before and I've always been careful, never had any issue like this, but this time really I don't know what happened and to be honest, I really love my S7 Edge, I don't want to replace it.

Possibly a hardware problem. You will have to take some technician for a more accurate analysis.

if it's hardware, why I didn't have any problem before updating the ROM? is it possible updating damaged the phone?

one more thing, I saw some people use a dongle called USB-JIG on dead Samsung phones, that enter phone to download mode and after that flashing with Odin.
do you think it's work on my phone?

It can occur, despite being very difficult. I already corrupted the xperia bootloader I had, but it never happened on my samsung devices. I even have a s7 edege and I am changing his rom and I never had any problems. As I said, you should take the device to an assistance center to get an idea of what really happened. Perhaps it could be a hidden problem, which was only expressed by changing the rom, or it could give the same problem with the old rom. What I can say is that a simple exchange of rom, would hardly cause a hard brick in a device.

You can also try, because if your device is not completely dead, it can come back to life with this procedure. But I still recommend taking the device in for a technical assistance.

There are 3 cases in this:
1. If you flashed a corrupted/wrong bootloader in twrp/flashfire or anything that doesn't blocks a wrong flash like odin. Your phone is dead for good. Only a usb jig/repair box or a local mobile technician can fix that.
2. Your phone is bugged with black screen. Installing a custom rom can cause weird things. Sometimes hard stuck with screen off/black .. now you need to wait for battery draining itself completely and then plugging in charger and trying to get in download mode. If you could go in download mode then you can reflash through odin and it will be back to normal. Although sudden turn off and then complete deadness is often a hardware failure.
3. If phone after draining completely doesn't shows life when connected to charger and can't go in dl mode then its either hardware failure or bootloader problem like in no.1 point. You will need to take it to a mobile repairer or use a repair box/jig nevertheless.
