Noticed my E900 was unexpectedly powered off. Tried to switch on and got the LG logo for 3-4 seconds, then... nothing. Seems to power off. Failed to boot?
Subsequently, power button did nothnig. After removing/replacing battery and powering on, I get the same LG logo for a few seconds, then nothing.
The LG logo tells me it isn't a dead screen. Connected to PC/Zune and nothing seen.
Are there any button combinations to do a reset?
I have ordered a new battery, but I think that's unlikely to help.
Any thoughts?
Thanks.

I had already tried charging the phone of course, and had left it plugged in for several hours. No change, still as dead as ever.
But later I connected to a PC. No sign of life from there, but I happened to leave it connected. An hour or so later I noticed it was displaying the almost-full-screen picture of a battery, with a small fraction of green at the bottom.
So it seems the battery had been totally drained to the point it was (almost) unrecoverable. Perhaps it was the low-current trickle from USB that got it going again.
Back up and running now. Glad I didn't panic and buy a new phone!

Hi, hope someone can help. Baterry went dead whilst on a call, it was low. Tried to recharge through USB "device not recognised". Tried power and Orange LED comes on momentarily then phone cycles through booting. Sometimes you can see the boot screen other time just the vibration is felt. Tried soft reset hard reset every which way power on whilst connected, power off etc. Removed battery tried again, same. Left battery out for 30 minutes, same. It now appears to be stuck in bootloader screen and still cycling. How long does one have to leave the battery out? What else can I try???
Jerry rigged another destop charger so I could align the contacts and got some charge in the battery. Put it back in and charging normally, phone booted up as though nothing had happened. No hard reset evidence.
So my phone ran out of juice 4 days ago, it was left uncharged till 2 days ago when i decided to charge it. I plugged it into the nexus 7 2012 charger (which i use to charge many other devices and none had problems including my nexus 5) and the LG logo showed up. After 3 hours i went to check on it and it was just dead and warm. It's completely unresponsive, won't boot into recovery or download, won't show LG logo no matter what button combinations i press. It's not recognized by my PC.
I opened the back case, pulled the battery cable and reinserted it and tried but still dead. When i connect the phone to any charger it warms up but is still completely dead. I tried booting it with the battery unplugged and still dead. What might have gone wrong?
Check voltage of battery (Should not be below 3.7v).
I had issue with mine when battery corrupted. Led was blinking red on charge/pc/power on
I don't think it's the battery, I've already tried booting without it and it won't boot or get recognized by the PC.
You saying about booting without battery, was it "test point" procedure?
I'm not really sure what you mean. I unplugged the battery connector and plugged it in the charger and attempted to boot it up. I was trying to test if the battery was the source of failure but I think it's not since it should have booted up if it was just the battery that failed.
Same with me. I bought a new battery and the same thing happens. Blinking red light. It shows some life for about 3 seconds with the logo coming up but then dies. anyone know whats going on?
Galaxy S4 GT-i9505, all stock, no custom roms, no rooting. With battery at approximately 15% phone died. First thought: battery dead. But phone not charging at all. Current problem: Sim+SD removed, insert battery, phone shows logo for 1 second, then dies, tried rebooting but nothing happens. Battery removed, after inserting WITHOUT pressing power button the same: logo 1 second and dies. Battery removed again, insert tried entering recovery mode, phone shows logo and blue letters "recovery booting" but after 1 second dies. When connecting charger nothing at all happens, no power up no logo nothing. Any thoughts? Searched forum but found no solution.
Sounds to me like the battery is completely dead. Try leaving it on the charger for a while? Try another battery?
It's the power button. It's stuck, that's why the phone turns off after 1 second and why it turns on when plugging it in.
Try to wiggle the button unstuck. You can soflty hit it with your finger.
If all else fails take it to have it checked and repaired. But I'm 90% sure it is the button. Had a similar problem on another S4.
Tried another battery. Nothing. When connected to charger also no red light to indicate charging of the battery. And no booting when charger connected.
if you have a multimeter, you could test the board connections on the power button.
1st. replace the battery.
Also not boot......??
Then Flash bootloader and fresh Firmware
Good Luck??
I was running a standard OS, no root/custom/anything (mostly because I couldn't find a compatible hack). Anyway, I had my phone running happily for ~2+ years, no trouble at all, but few days ago I left it charging for 2-3 days (it powered down due to lower power before that). I've done it before several times, but when I tried turning it on, it was stuck on Samsung logo (white on black). I restarted, it was stuck a bit further on the colored startup animation. Third time, stuck on the logo again. I turned it off, but it was a bit warm after 10 or so minutes. I tried charging it - it showed the usual green battery charging from 80% or so. I took the battery out, pressed the power button for a minute for some hard reset, but the battery back in, and from that point on it seems I have a brick. No reaction to power button, no reaction to charging. Power+Home+VolUp produce no reaction, either.
Is there anything I can try, or should I just give up?
Factory reset ??
Flash stock rom via Odin ??

The only answer I can think of is that your battery is dead. I would try to use another battery before getting to the conclusion that your phone is completely bricked. Or just let the battery out of your phone for a couple of days and try again later.

Can't do either since the phone is not turning on.

Tried a new battery, the phone still won't turn on. No lights, no charging screen, no activity.

Must have fried something. The only thing I would check now is to connect it to a PC with a USB cable and see if the PC detects something, ANYTHING. If it makes sounds that something has been connected to it. I remember when I hard bricked my phone, it did not turn on at all but my PC still sort of detected it. I guess that is the only thing left to try to give you a definite answer
Hi all. my Samsung S7 Edge was working fine albeit a bit sluggish at times but it was okay. I was down to 14% charge and so connected it to its Samsung charger with a non stock cable which is its usual charging process. It was otherwise okay and the screen went off so it was completely black, the red charging LED came on and I left it like that for a little while. It is still in that precise state and no sequence of button pressing for any amount of time gets any response at all. Nothing, no vibrate, no charging indicator, no flicker - absolutely nothing changing. Red LED and blank screen, no response. I would like to discharge the battery asap and have clamped the Vol- and on/off button pressed for 20 minutes and it is not connected to anything. It is not rooted and there is no response if I connect it to a computer. Is it bricked? How can a phone 'brick' while working as it should?
So I removed the back, disconnected the battery for a minute or so and reconnected it. The red light had gone off and now nothing, no light at all and it is connected to the charger with the Samsung cable. I have tried a different charger - my laptop. I happen to have an unused battery I was going to replace this one with so I have now also tried another battery. The phone is just dead and no response at all so I guess there is only one option - bin it!
Well I happened to have a smashed S7 Edge so a working motherboard which I replaced and obviously cured it. Restoring as much as I can remember but can anyone still suggest anything I can do that may kick start this motherboard?
The same happened with my S7 Edge, yesterday. Just a blinking blue led and I couldn't turn it on. So I waited till the battery was empty and tried to recharge it. No red led no button combos are working, nothing. The phone is dead.
Was there an update?
