[Q] Mysterious S4 - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Recently purchased S4 SGH-I337M locked to Bell. Before I paid for the phone I installed CPU-Z and Genuine Galaxy apps just to make sure it is not fake S4. Both apps showed the phone is genuine S4. The phone looks genuine inside (I checked the motherboard, camera, etc) and outside (thin frame, power light far from the speaker, etc). The phone is running offical ROM.
However, I can't put the phone in download mode using buttons. Tried all possible combinations so many times. I can put the phone in download mode using ADB but even then there is nothing on the screen. I was able to flash the latest official Bell firmware via ADB hoping the new flash will enable download mode. No luck. Still no download mode. When holding volume down, home and power buttons the phone vibrates, I let the power button go and after that nothing happens. The screen stays black. I tried the combination without home button, just volume down and power button. Still nothing. When using the phone all buttons work properly. I am able to put the phone into recovery mode no problem. Recovery mode displays late (I need to wait for 7-10 seconds) but it looks and works just fine.
One other thing that is also strange - there is no "Samsung Galaxy S4" logo when the phone boots up. The phone stays black and the first thing it shows is the Samsung booting animation.
Just wondering if anyone has seen something like this before?
What could be the issue here?
Thanks in advance for any help/suggestion/advice.
I apologize if I posted this in a wrong category.

I had a similar problem as most phones in Canada seem to have Download/Recovery mode disabled, and here is what worked for me.
Grab something like One Click Un Root (all models), and click one click un root (obviously phone has to be on and plugged into the computer).
This should automatically reboot you into Recovery Mode!
All you have to do is "wipe data/factory default" or something like that (should be the third option).
As it states, you will loose all your data, but at least you will have a functionning phone!
did it work?
Hi. I have similar problem. Can anybody give instruction what can I do?
I have this problem too. Please help somebody
Add me to the list. Bell Galaxy S, went to unlock my phone the screen went black. Now it will not boot into the OS, the galaxy S splash screen displays then nothing. The menu and back button light up, thats all. ****[email protected]@
I have not rooted or anything.
Of course my download mode does not work.. Going to try this one click root thing if I can find it.
NOT HAPPY
This is not working. Probably because the phone is not in USB debugging mode as I can't change it... Is there any other way to get the phone into recovery mode?
**** me
i had the same thing happen to me the other day with my bell galaxy s and my phone wont do the 3 button combo trick. i left my phone plugged in to a wall charger for a while until the back of the phone became a little warm. i pulled the battery and then left the power cord plugged in and put the battery back in. i held the volume down and enter button until the battery charging indicator showed up, then i also pressed and held the power button until the boot animation started (this is the blue moving swirl and music, not the galaxy s splash scree) and then i let go of the power button. it took a few attempts at this before it actually worked, but eventually it will go into download mode at which time you can open the odin app, then plug in the usb cable and flash your phone that way. it did seem to make a difference if the back of the phone (around the camera area) was warm. if i let go of the power button while the music was playing and the phone did not enter download mode i would keep all 3 buttons pressed until it shut down again, then i would only let go of the power button while the phone initiated the charging screen, then once the battery logo was displayed i would hold the 3 buttons again and would just keep doing this until it went into download mode. i have flashed it at least 5 times today and i have been able to do this each time.
i also had an issue where odin would not recognize my phone was plugged in and windows would show a message saying the usb device was not recognized. i left the phone plugged in and while in download mode i pressed the volume up, enter button and power button until the phone went blank and when the galaxy s logo showed up i let go of the power button and the phone would go into recovery mode and then the usb drivers would be installed. i would then do the 3 button combo for download mode and odin would work fine. it took several attempts but it does work. i hope this helps you guys
If I hold all three buttons the splash screen does not come on, it just keeps looping the Galaxy S logo until I let go of the power button....

That's what mine did too, several times in a row and then it worked. For some reason it only works after the battery is charging for a bit and the back becomes warm. then it works at will
No luck. I am probably screwed getting it exchanged now too as I am passed the 14 days from Best Buy.
the on click thing doesn't work, if your phone is already bricked.
also it is not the phone's fault for not working, the phone was working properly before you tried the hacks.
whenever you do these kind of things you know you are entering into the "not supported" "not covered by warranty" zone.
in the worse case scenario, if you can no enter download mode to recover your phone, it'll be to take the phone back to bell and claim warranty on it, and prentent you don't know what happened to it.

Its my fault??
I did not hack my phone. Its not rooted, I did nothing to it.
By "unlock" I meant exactly that, unlock as in swiping the screen to unlock it.
The more I search the net the more posts I find of Galaxy S phones randomly bricking...
on the original message sounded more like you went to Unlock the phone, as in SIM unlock the phone using any of the tools available out there, and there has been already several people which had the same problem.
if you go back to Bell for an exchange, you better not use the word "unlock" rather use Swipe
as the message on the phone "swipe the screen to unlock"
there are no known issue about this causing the phone to brick.
if that is what happened to you, you should have started a new topic for people to help you, instead of hijacking the topic from the OP, as your issue is different from OP, the OP actually screwed up because he/she flashed the wrong ROM to the i9000
... anyways, Does it work if you reboot the phone?
I have rebooted the phone about 100 times. The phone crashed when I unlocked it to check a text I received. (not hacked). Has not booted up properly since. I have found many others with the same issue who have also not hacked/rooted/unlocked/ their phones.
Waiting on Best Buy to call me back. I am so pissed right now, I have been bragging to my friends and co-workers how awesome this phone is, one has already picked one up, I hope his doesn't brick too. Not recommending it to anyone anymore..
did you load a lot of MP3 to the phone?
can you boot into Recovery Mode?
in the recovery mode you can wipe the Cache and wipe the data
that should make your phone work normal again
it'll be best to open a topic to help you trouble shoot your interesting issue, as it's the first i've hear that you get a black screen after Swiping out of the lock screen
I can't get into recovery mode. I have tried every button combination I have found. I had about 2 GB of music on the phone. I also installed the Android SDK to try ADB, but since the phone is not in USB debugging mode it does not see it.

on the other topics relating to the 3 button not working.
have you tried the heating up method?
or the plugging the battery in, when all 3 buttons are pressed? (of course for this one you will need help from a friend, unless you are very skilled at keeping the 3 button on hold meanwhile able to slide in the battery in with out a 3rd hand)

Galaxy S black screen

Hi all, I have a galaxy s and was going to install a new rom. I saved the rom to the sd card and pressed the power button to go into recovery mode, the screen went black as usual but never rebooted and the screen stayed black. I connect it to the pc and it tried to load some driver something to do with "test driver" but anyway the screen stays black and the phone does nothing. Any ideas how to fix this without sending back to Samsung. Thanks for any ideas. Wayne.
Does the phone show the samsung logo at the beggining or is it just dead black?

the same problem with me today blank screen, no vibration, no download/recovery mode, anything. The only sign of life is when I connect it to my PC, it detects a new device named SEC S5PC110 Test B/D , request a driver
You should send it back to Samsung. I'm thinking that its more than a software (ROM) problem when even download/recovery mode isn't working.
Same happened to me, try to get your phone back in restore mode with the three button trick. Amd reinstall the image again... it will work..
mine is just black does nothing except request a driver when i connect it to a pc. SEC S5PC110 TEST B/D. thats all it will do.
It is probably the deep sleep coma bug (I've had it ever since I flashed to 2.3.4).
Hold the power button down for 10 seconds and it should reboot the phone.
Remove the battery, leave the phone disconnected from the PC and get the phone in restore mode. Then when that succeedes, connect the phone to the PC.
I heard this problem in other forums when users flash a wrong rom or firmware. Only samsung can repair your device.
Try to access download mode: vole down button + home button + power button if you can access this let me know

Galaxy S5 won't turn on

Hi,
unfortunately I have a problem with my Galaxy S5 running CM.
Some days ago, the power button got stuck in the case so that it was pressed for quite a long time. When I tried to turn the phone back on it only showed the logo for a while, vibrated and rebooted.
I tried to boot the phone in safe mode which didn't help and then in 'transfer mode' (sorry, I don't know the right term. I think it's the mode where I transfer a custom ROM). The latter without connecting to a computer so it said something like 'transfering, don't turn off' for a while. Eventually, I had to turn off the phone cause nothing happened.
Now, when I try to boot the phone it just vibrates and stays black. Not even a LED flashes. When I connect it to my PC it vibrates and the PC recognizes something but doesn't show any connected hardware. It just installs a driver.
People at a repair store said the screen is dead but I don't really believe it because there was no physical damage of any sort.
Is there a way to repair my phone?
If you turned it off mid flash you have no ROM. There's nothing to boot. Use volume up, power and home while booting. Load recovery. Flash the ROM and don't stop it. If it doesn't work get a different ROM and try again

Samsung S4 stuck on first logo screen

I only use my S4 to listen to Spotify and Podcast, no other apps are present. I use it until I the replacement Headphone thingy comes for my Nexus 5x.
It's my old phone and it worked great until yesterday when my screen went completely pink and then my phone restarted. Now it's stuck on the first logo screen.
Not the Samsung animated logo screen, but the very first completely white text Samsung Galaxy S4 logo, I can't post pictures.
I am using a Cyanogenmod Rom because of the memory leak bug on stock rom.
I can't boot to recovery because it just boots for few seconds, then shuts off, vibrates 2 times and goes back into the boot screen where it's stuck.
The vibration thing happens everytime I try to boot the phone. The logo comes up, it shuts down, vibrates twice and then it gets stuck on the logo indefinitely.
I can boot to Download Mode and I can't boot to Safe Mode.
Any ideas what I could do? I really want to listen to stuff again.
Could be a power button issue. Open the phone, clean the power button contacts with a bit of pure alcohol, quickly press and release the power button several times in a row using a bit more pressure than usual, reassemble the phone, and see if it works.

It's still stuck the same way.
When I got to the Recovery Screen once, the screen turned yellow and phone restarted.
The power button may need to be replaced. Do you have a multimeter to test the connections?
@audit13: I've got a feeling the power button isn't his issue. On a properly working S4 the screen wouldn't flash a particular color before rebooting. Given that this happened to him suddenly, I think he has an issue with the SoC itself.

I have a almost dead S4 i9515 model here, it stopped working.
Here at home I plugged it in and it vibrated continue and nothing more.
Tried a couple of times to go to recovery (unrooted, so the standard recovery) and one time I got a Samsung logo with something blue in the top left side of the screen and nothing else.
Cleaned the power button and started the phone and got the Samsung boot logo, but it got stuck in the logo loop.
How can I check the power button with a multimeter? Is there a trick to get to the connectors?
You need to remove the back frame to access the power button connectors. There should be there of them. Without the power button pressed, touch the probe across the outer two and see if there is any current being passed.

Will try it this weekend, if it is the button I will just take it out, and try it that way till I get a new button.
Thanks for the tip!
Well, the button was not the problem, see next post
While starting it won't pass the Samsung logo boot,
while starting via recovery (power, home vol-up) I still won't pass the Samsung logo screen, but now with the message in the top left screen 'Recovery Booting...'
It's dead I believe, the power button is okay, but after a few difficult boots, it wouldn't pass the Samsung logo.
But now it doesn't respond at all anymore.
Is there a way to access this phone?
Via adb or Odin? I don't think so, if the phone doesn't startup I can't do anything...?
It is bye S4 I guess...
I am blocked here too with a GT-I9506, and can't fin anything, so yeah, i guess it's dead, mine too
Time for something new...
Anyone managed to revive his I9506? I have similar problem, if you can guys look into it and tell me that you have tried this already:

I think it will be the best way. It's third day of flashing stock firmware from 4.3 to 5.0.1 NEE an TPL. There ware two times that phone actually booted to recovery and green android appeared. But then phone rebooted and still can't get up.

s7 edge need advice

hello apologies if this is the wrong area, after some advice regarding my old s7 edge.
not used it for 18mth, i seem to recall i flashed a rom onto it but not sure which one, anyway tonight found it and tried to turn it on, it briefly powers up the display is like a static tv screen and it says along the top "kernel is not seandorid enforcing" and it has now gone to a black screen i do not know if the phone is off or on, tried to reset using home power vol up/down buttons but i get nothing. i put the phone on charge for 30 minutes nothing seems to indicate if it is charging or not except the chargers power light stays on.
anyone any ideas if i will be able to recover the phone or is it now a paper weight?
i am going to guess the phone is at this moment dry of charge except for the last 30 minutes and it still seems dead.
thanks
Try booting into download mode with vol -, home, power. If you still dont see anything, wait a few seconds then press vol + like usual and check if it's recognised by odin. If it is, reinstall the full stock firmware.
Also consider that if it doesnt boot into download or recovery at all, the home button might be broken. Theres no way to tell without a working system and the combinations without home just force reboot your phone.
Ps Questions usually go in the Q&A section for your device, dont get confused if this thread is moved to
https://forum.xda-developers.com/s7-edge/help
The people there propably know more about your specific device.
