dead s4 - Galaxy S 4 Q&A, Help & Troubleshooting

my s4 is a year and a month old and yesterday i put it to charge before bed like i always do. i heard my phone vibrating and i figured it was a text. after an hour i go to check the phone and it is off. i tried to turn it on and it had no led or any sign of power even while connected to the stock charger. i knew something was wrong when it wouldnt wake after holding the power button and the volume buttons and then removing the battery and replacing the battery. usually when you take out the battery and put it back on it vibrates but i got nothing. today i tried my friends battery on my phone and saw so signs of it getting power. i also tried my battery on his phone and it powered up fine.
i just got off the phone with t-mobile and the warranty has expired since its been over a year since i got this phone. there is nothing they can do since its a hardware issue. is there any possible known way to try and fix it? even if i gotta gut it up to check a connector or something. the rep said maybe something isnt making contact but i havent dropped my phone in a while and has always had the gel rubber around with a hard shell supporting the gel so no physical signs of damage. the top half does get hot when i put it to charge but not the battery so no clue what could have cause this. i dont overclock it or anything special kernel modifications just a stock based rom which i have had for months now.

My phone just won't boot up at all... no lights or anything

Hi, I have a major problem with my G1, it will not boot up at all now.
To make a long story short. Every couple of days my phone would not wake up from sleep mode. I thought I was having the issue people were talking about here:
http://forum.xda-developers.com/showthread.php?t=528191
So i reverted back to Jesusfreakes 1.5 firmware and it kept happening. So i moved all my apps back to the phone and in fact removed all widgets and really jsut kept a couple of apps.
Anyway this has still been ongoign, usually though i just have to take the batter out and put it back in and we';re in business.
Today though... it's another story. The phone will not start up at all.
I pressed the red button = nothing.
i pressed the red and home button = nothing
red button and camera = nada.
I plugged into the power, a light doesn't even come on the phone. I laeve the battery out or in same thing. I even took out the SD card....
I think the phone just died on me... Anything else you guys can recommend I do?
Take out the battery and hold the Power button for 10-20 seconds.
Plug in the power adapter (without the battery) and see if the LED turns on.
Put the battery back in and see if it turns on.
Does your computer recognize it at all when it's plugged in to USB?
That's about all I know, if you don't see the charging light after you reset it using the power+no battery suggestion, I'd think it would be a hardware problem.
Well I wasn't having any of the waking up from sleep issues. But I did have my phone completely die on me. Same symptoms, it wast responding with anything I tried, and the notification led wasnt working either. I even tried another battery and what not. So this what I did:
1st I pulled the battery out and my sd card for a few moments, the plugged it back in... nothing
Then I let the phone on charge for about 16 hours (some1 suggested this, because messing with the SPL can send ur battery to -110% and takes about 14 hours to revive it. (this didnt do anything for me, but it may have helped I dont know)
Finally I took out my battery, my sim card and my sd card, and let the phone sit for like 10 hours or something, popped my battery back in, and the phone came back to life!
give it a shot, andd good luck
Thanks, i'll let you know in 2 days how it went
in the meantime i called HTC, they seem to know about this issue. He said they'll probably have to swap out the main board but i have to call during business hours for the repair department.
He told me to emphasize that my phone was unlocked so they return it that way also. Since they're putting a new mainboard in i'll ask them to put the rogers one in instead so i can get 3g (I'm with fido in canda 1900mhz)... Let's hope their customer service is extra willing to help out
So my phone was covered by warranty! I guess a dead motherboard does not show the kind of firmware running on the device hihi.
They tried to put a Rogers compatible motherboard in but it failed testing (I have a t-mobile device running on the Canadian network) so they inserted another motherboard. She does not see if it's Rogers or not though but she suspects it's a T-mobile compatible one. They also replaced my antenna.
Can't wait to get my G1 back!!! this Treo 650 is way to bulky

[Q] I9505 died suddenly now wont charge

Hi all, tried searching for some help but couldn't find anything of any use, plenty of similar things only but not quite the same.
Basically, my phone had been in use today, as normal, nothing different, nothing new installed. I put it down on the table while I did some work around the house, an hour late I picked it up and it was off. It had around 70% power when I last looked at it, Not only had it turned off, it was so hot I couldn't hold it for more than a moment. After letting it cool down, I tried to turn it on and nothing at all happened. I decided to plug it in and leave it to charge a bit, but when I came back to it again half an hour later it was still dead and hot as hell again.
I have tried three different chargers and even a new battery that I bought in town just this morning, thinking the battery was the problem. Still exactly the same thing happening with new battery, wont charge, phone heating up within minutes to the point where I cant hold it. Heat seems to be building up underneath the memory card slot.
I did manage to boot it up briefly whilst it was plugged in before it got too hot but had to turn it off again to cool it down. It seemed to boot just fine on that occasion. Also managed to get it into recovery and did a cache wipe as well as a full factory wipe but no difference. Again I managed to boot it after the wipe, seemed to start up as you would expect a first boot to do, asking me to set up the phone, but again it was no gaining charge and was heating up very fast so had to turn it off again.
Any ideas what the hell has gone wrong with me phone?
I have a repair pack from Samsung on route as its only four months old, so they will do a warranty repair or a swap, but while I'm waiting, thought it best to ask here if anyone has any ideas.
Sorry for such a long post, if I need to post anything more specific feel free to ask.
Thanks in advance
I experienced such before...
Phone heats up a lot and shuts off when charging. I send the phone in for repair, the service center identify it as faulty motherboard and got a replacement handset...
It is just bad quality components in Galaxy S4. Go and change your phone at service center.
Thanks for that, I had a feeling it was motherboard, processor or USB board, Was kind of hoping I was wrong and there was something I could do at home to fix it but oh well...
Does it matter that I have the new German 4.3 firmware on a UK handset with multi-csc? Knox flag is still 0x0 if that matters to warranty lol. I cant flash anything stock if I cant turn the thing on lol.
Why is the S4 such a poor quality phone for a flagship, seems to be so many faults with the phone and battery. I've had both the cracked screen issue as well as this crash for no reason. My S2 on the other hand is still going strong and working perfectly despite being dropped a few times and having had no new parts or battery replaced. Its covered in marks and dents from prolonged use and still keeps going. Had that since launch. Back to using it while waiting for the four month old S4 to be fixed.
EDIT:
Strange new development, the original battery doest do anything any more. Nothing happening at all, no charging screen, no heating up, nothing. New battery still not charging and causing phone to heat up. Did manage to boot the phone up again for a few minutes last night and besides heat and not charging, it seemed to work. Making me think its not the motherboard at fault now or surely it wouldn't turn on. No idea what's going on now.

[Q] LG G2 D800 Help needed. possibly bricked. yes really..bricked

So yesterday my phone worked great. I work outside for the most part. It rained its ass off. Phone did not get wet that im aware of. no water drops or anything on it. Had it inside my waterproof jacket. This was early morning..10am or so. I get home from work around 7pm. Phone still works. battery is getting very low though. At 8pm phone reboots..which it randomly does sometimes. I set it down, come back to it awhile later and realize it never came back on. Figured the battery was completely drained past 5%. plugged it into stock charger (not stock cable though but a highend cable still). Phone wouldnt boot up or power on or even show any signs of life. Tried other cables, charges, USB ports on computer, even car charger. Nothing. Set it on charge over night. Still not even a LED blink. Set it on car charger all day while at work. Not even a blink. I took it apart (taken many phones apart in my time haha) disconnected battery and plugged it in...nothing. tried power/volume down, power/volume up, all 3 buttons. held all button combos for over a minute. Still nothing at all. I have a new battery on order that I can slap in there and see if the battery is just completely shot but does anyone else have any ideas on what i can do to get it up and running again? Already had to buy a new phone G3! because i HAVe to have one for work. So i want to get this one working again so i have a backup in case this ever happens again.
Thanks for any and all help

tried to enter download mode, recovery mode, every mode i know of. with no luck.
and forgot to mention. when plugged into computer the computer does not notice anything has been plugged in at all. no sound at all. nothing under device manager
well i got the new battery in. didnt work. still no power at all. anyone else know of something i can try? i know the screen isnt dead because it would still give out sound when turned on or vibrate. but that doesnt happen either. is there some other thing i could test? how would i test the motherboard? power button?
This sounds like exactly what happened to my phone about two weeks ago. Phone was randomly rebooting one morning in strange intervals. Once or twice an hour at first, then more often as the day progressed. By the end of the day the phone wouldn't even turn on anymore. I had thought it was the battery as well but after bringing in to an electronics repair shop, it was diagnosed as a bad motherboard and the guy quoted me $130 to replace it. Considering you can buy the D800 off contract brand new for about $220 off the internet, I declined. I'm still really upset about it. I had already had it replaced by AT&T while it was under warranty. However, now my warranty has expired. I really liked the phone overall but now I'm not so sure I trust LG's hardware.
I'm using my brother's old iphone 4 now and it drives me flippin' crazy. I want to get a new phone as soon as possible but I don't know what to get. I'm so torn on the whole issue. Was thinking about the S6 but I've had bad luck with samsung in the past as well. I'd get a newer iphone but ios is so lame compared to Android. I hope you find a better solution than I did. :crying:

Phone just died in my hands after removing the charger.

Hello guys,
This just happened.
I left my phone charging, and when it hit 100%, I disconnected it from the charger and then I was going to put it in airplane mode, so I could go to bed. When I pushed the status bar down, the phone froze, 5 seconds later the screen went black and it wont turn on now.
When I plug the phone on my PC, there's a sound notification from windows, just like when you plug whatever USB device, but the phone is absolutely dead.
Holding the power button doesn't help. It just got out from warranty last month.... Full stock phone.
Does anyone know how to fix this?
50/50 chance a new battery might fix your problem. But if your not gonna do it yourself might be time to throw in the towel.
Similar event happened with me, phone died abruptly service center people told me that pcb has died and needs to be replaced, will cost more than 300$ for a new pcb. This phone has got really poor quality hardware component can die any time. Never gonna buy huawei built phone in future

I haven't had any problems with the battery whatsoever, it was fine since day one, a little but totally normal wear. The phone charged fine everytime also.
I stopped by in a service shop, they don't mess with nexus devices and they don't know anyone who does (Nexus never came to my country, so it's a rare device to see, iPhones, Galaxies and Moto G are kings here)..
Anyway, I tried everything I could. Hair dryer, downloading build with QFIL, holding the power and volume for more than 20 minutes, leaving the charger on for 24h and everything else I found online and the phone didn't even tried to recover, so I pulled the trigger on a OnePlus 5T. I hope this one lasts me for 5 years, like I was planning with the N6P.

Tab E suddenly dead, won't charge, gets very hot near camera when plugged

Hi everyone,
I have a strange situation, yesterday my son plugged in one of those cheap USB fans to his Tab E 9.6, and he said battery went down to 60%, he unplugged it, later we noticed the tablet would not turn on.
It's SM-T560NZKUXAR, I've been trying to charge it, it gets very hot near the charging port/camera, and nothing on the screen.
I pressed and held the power+vol down button, and I get a "no battery / plug in to the outlet" icon on the screen, when I do, nothing happens.
I was able to reboot it once and it got to the home screen but turned off because of 0% battery.
I was able to get it into recovery too, so it's not a software issue.
I assume the USB fan messed up the battery or fried something in there, is it possible to replace the battery or anyway to test it? Or off to the boneyard it's going..
SM-T377P sudden RIP
Hey did you ever find a solution to this? My Tab E 8.0 did the exact thing you described, almost word for word, just out of the blue a couple days ago. So now it won't power on at all, and the only thing I've found suggests it needs a battery replacement, which would be a huge pain since the back cover isn't "supposed" to come off, so it would more than likely need very precise and involved dismantling or I'm thinking I might just have to take it to the nearest uBreakIfix and hope they don't charge a crazy amount to check/swap the battery. If anyone knows of a simpler solution that doesn't involve "surgery" on the unit itself then I'm all ears.
And just to clarify, I wasnt doing anything power-intensive like your USB fan or anything when it happened, so you might be able to rule that out. I just had it plugged in charging and noticed the battery went down insanely fast when I took it off the charger and the top of it was hot to the touch, and then boom it was dead without any way to turn back on
