The other morning I woke up and my phone would not turn on after being on the charger overnight on the night stand.
I removed the battery, power drained the device and still the device would not post.
So I grabbed my spare battery and tried that, still no post.
I plugged in my device and noticed the charging light was not coming on, so i tried a different adapter and yet again no change.
I disassembled the phone and swapped out the USB flex cable with a new one, still no change.
So I plugged the device into my computer and I received a battery gray battery image that flashes away almost immediately.
I unplugged the phone held the power button down and plugged the phone back in. I received the Samsung writing with the model number but the device just goes back to the grey battery and flash away,
I attempted to boot the device to recovery mode but it just loops back to the grey battery,
I had then decided to try download mode with odin and restore the stock ROM. I can get the device into download mode but no computer recognizes the device in device manager or odin.
I have removed and re-installed the battery while in download mode and any computer will still not recognize the device.
I noticed one strange thing. If i remove the USB cable from the phone while it is plugged in the phone powers off and will not turn on until it is plugged into a power source.
It is almost as if the phone does not recognize that the battery is even plugged in!
If anyone has any ideas or could possibly point me in the right direction that would be greatly appreciated!
Thanks guys in advanced if anyone can offer any information on this issue!
Also, the phone is out of warranty!

Omnia 7 with Mango RTM officially installed, working perfectly was recently let to sit idle while I was using my Focus, and the battery drained over time.
Today, I wanted to charge it, but plugging in the USB did not power the phone on. I even changed cables, and also used my PC to charge it - but for the life of me, it wouldn't turn on. I even let it sit with the charging cable in it for a while.
I also took the battery out and only plugged the cable, still nothing.
Is the phone dead? Can anything be done to revive it - it was a flawless phone and there were no issues as such. I would appreciate any help.
Update: I plugged in the USB jig which powered the phone on, but now it's in the download mode. Powering it down and and trying to restart it again I am hitting a dead end. It's not powering on. Anyway to restart the phone without removing battery?
Update 2: I remembered from the past trying to update the ROM, that it fails and restarts the phone. So, while in the download mode, I started the ROM updater from Samsung and ran through the normal update process. It failed and restarted the phone - now I see a big white battery charging icon on the front screen. So hopefully this will be ok - and I will update the progress.
But this is quite disturbing as to what steps I had to take to power it on. Imagine if I didn't have the USB jig.
Update 3: After showing the battery icon for about 5-10 minutes, the phone restarted itself and booted normally. It's now charging and hopefully all will be ok. I'll make sure I don't let the battery die again.
Hey all.
So I have an s4 that was running safestrap and hyperdrive. It all worked fine and I was having no problems. The phone froze (programs not responding, not a big deal.)
I did a battery pull and then the phone would not turn on again. When I put the battery in, it turns on for about 5 seconds. I managed to get it into recovery and download mode, however it turns off almost as soon as I get there. I checked with a different battery, but nothing.
I would ODIN it and everything would be fine, but it won't stay on long enough for my computer to even recognize it.
Also, I tried leaving the phone on the charger overnight, but it won't charge the battery or show the red LED. I felt for heat to see if it was hot around the usb/charging port but it wasn't.
Any ideas?
I'm sure you tried this, but did you try to use the USB cord to power and not rely on the battery?
Hi all, and merry Christmas to everyone.
My S7 edge has started to cause problems with charging up, for some reason when phone is turned on, it will not recognise the USB cable. - I have tried a different cable and plug and it still does not work.
When my phone is turned off, each time I plug in the cable I get a battery with a white lightning symbol and then it just goes off nothing shows as charging . So I suspecting the USB port is OK?
I have erased Delvik cache and erased data this does not change anything.
I do however get VERY VERY slow charging when I leave my phone is download mode.
Anybody got any ideas on what to try before I end up getting back in touch with vodaphone?
Thanks all.
UPDATE :
My phone is now completely dead on 0% battery. When I try to turn on the phone nothing happens as expected with 0% battery.
If I then plug in my charger, I get the lightning symbol for 3 seconds and then it goes off. It gives it some kind of a "charge" and I can turn on my phone.
Once it boots back up, their is no indication to say my phone is on charge and the 0% stays their with a red explanation mark and then my phone turns off. back to the stage I cannot turn it on unless I replug the charger cable and then it goes back in the loop.
sounds like the battery has failed.
check your usb plug if theres any missing pins.
Have you tried using a different charger or charging from a PC USB port ?
Looks to me as if it's your charger or your battery which is faulty.
Yes, I have tried a different Plug and lead we have several in the house. too many samsungs haha.
Sounds to me the battery is faulty as well :/ . Im curious as i thought if the phone is plugged in maybe it should stay on and if i then unplug the phone it would turn off instantly?
I contacted vodaphone , i need to pop into their shop on Monday (i think their open) . they have their own repair center in store which sounds good so no need to send phone off for a repair and they give your a courtesy phone to use as well. If they cannot repair it i should be entitled to a replacement.
Worst thing about these phones when you cannot take battery out :/
Thanks Guys . Hope you all have a nice Christmas Day and get what you all ask for !
on 2nd thoughts,
Although this sounds like a battery issue, of course my phone is totally dead wont turn on. but when i plug in my phone to either, the wall or PC. it will turn on and then back off as if the battery has just died.
If i plug the phone into my PC in DOWNLOAD mode, the phone will stay on but my computer doesn't even respond as if nothing is plugged in. This tells me the problem may be more than just battery?
Just a thought.
I have a USC S7 edge. Stock rom, no mods. My battery life is toast so I opened the phone to replace the battery.
I changed the battery. Plugged in for the first time and all it did was flash the battery icon with the lightning bolt when plugged in. Wouldn't boot.
So I tried the power with home button while plugging in, it brought up the galaxy s7 logo and just went into a boot loop doing that.
Next, I tried booting into recovery, and now it whenever a charging cord is plugged in, the recovery booting logo just flashes. I can get it to go into download mode only when plugged into a wall charger. It won't go into download mode when plugged into a computer.
I removed the battery completely and it exhibits the same behavior when plugged into USB.
Any ideas? Is my device bricked? Could it be just the battery is defective? I can't test my old known working battery as it was discarded. I have another battery on order and it should arrive in a couple days.
did you make sure that nothing was disconnected or moved when replacing the battery.
you may have partially disconnected a cable when opening your phone up.
When I bricked my phone I went into recovery and reset everything but after it went into the loop you are describing. All I did was boot into download mode and flashed stock to make it work again.
Any advice on getting it to go into download mode when connected to a PC? Mine won't- perhaps thats due to the battery.
It will go into download mode when plugged into a high amp wall charger
Saw today that there was the MIUI 14 Update for the POCO.
Downloaded, unpacked and then it said restart, pressed restart.
It turned off and never on again.
Tried holding power button, charging, fast boot, holding here and there nothing. Blackscreen.
Opened the phone, unplugged both screen and battery, plugged in. Nothing. Tried it a few times and then upon charging it installed the updated, turned off blackscreen.
Tried everything from above again, nothing. Saw that upon plugging on my PC it showed QDLoader 9008 so probably EDL. If i unplugged and plugged in I heard a sound on my PC. If i held the power button i also heard the sound when you connect a device.
Opened the phone up again, removed the mainboard and tried to remove that small metal cover from the mainboard. Couldnt get it off even with enough heat applied. Heated the mainboard according to a different thread: Mainboard Part
Now when i charge the phone it shows me the battery display but if i press the power button the phone doesnt boot. Without charging it also doesnt show any sign of life. I didnt plug in all parts such as camera etc. yet
Does anyone know what to do now, cant afford a new phone.
edit//
If i plug it into a charger it shows 90%
PC shows it as a drive (E:/) Linux no more 9008
still no reaction after connecting everything

When the phone is connected to edl mode, the next procedure for recovery is simple, you have to look for the procedure, for example here.
I solved it by heating up the metal cover and the mainboard as shown on the "mainboard part image". If you reasamble the phone make sure that your mainboard is connected to the button connectors, that was my issue. For some reason it wasnt connected and therefore the buttons were not working.
Support was literally useless and the warranty in germany is a scam.
Trash phone. Never going to buy POCO again.
