My LG G2 (rooted with AOKP ROM a month ago) just got bricked about an hour ago. It was completely random too, I had it playing music via bluetooth in my pocket and all of a sudden the music stopped and when I took my phone out of my pocket, it was unresponsive to any button pushing. I plugged it in to my computer to see if I could debug it on there since the screen was completely black no matter what I did (long-pressed the power button and tried hard reset but still black screen). So when I plugged it into my computer, windows said "USB device not recognized" so I can't even do anything with it. I have no idea what to do and am in need of some help . I tried to include all the relevant information and if I missed anything, just ask. Thank you in advance for any advice you guys can give me.
Plug it into a charger and try different button combos, holding them for up to 30 seconds
power+up.. etc
Can you go into download mode ? (while powered off. press volume up and insert usb cable)

Hi all,
I got a Samsung Galaxy S (i9000) from a friend who wanted to toss it away since he says it is broken.
I want to see if it is or not.
When I try to turn it on, complely nothing happens. When I put the charger in (or the USB cable fot that matter) a battery sign appears with 5 dots under it which move from left to right. When I try to switch the phone on nothing happens
When I wait a while, the screen goes black. When I try to switch on, nothing happens.
When I push the home button, the green charging battery appears again and the back an menu button light up.
A factory reset is not working at all. Can it be that the power button is broken??
Any help would be greatly appreciated!
Regards,
Vincent
Fixed it!
Hi,
I was able to fix it.
Thanks to this sticky: http://forum.xda-developers.com/showthread.php?t=1134975
This is what happened:
I tried just about anything, nothing worked. Then I saw a reply in this thread someone mentioning you should plug in the usb cable, push both volume keys and then maybe it could work. But of course, mine didn't.
Then I started experimenting, what did work was this
- take out battery
- connect usb cable to laptop
- push volume down + home simultaniously and then put battery in
Now i got into download mode (yellow robot and triangle + warning not to turn off target) and with Odin I was able to start the phone.
I then found out that the power button was indeed broken!
Phone works like a charm. Only thing is when I have a dead battery that I have to use Odin to start the phone. I will seek for a way to fix the defective power button.
Hopefully it will help other people with this problem!
BTW, thanks all for all the help
Hi all,
I have a LG G2 from AT&T. Had it for about 1.5 years now. No issues until now.
I was just watching some YouTube videos and the phone suddenly shut off. I tried the power button and it won't turn on.
I plugged the G2 in to a power outlet, but it was just stuck on the "LG" screen. I unplugged the cable, and now, even when I plug in the cable, the phone won't turn on.
Can someone please help me? Thanks in advance to anyone who can.
I believe it's due to the motherboard, but I'm not sure.
Really would like someone's help!
Bumping. Really need help with this.
Can you put it in download mode?
Plug in your usb cable from pc holding vol down button, if nothing happens, try at the service centre because it can be hardware related.
The phone doesn't do anything when connected to the laptop with the button held down. :/
Hi! I managed to hard brick my galaxy s7 edge and i wanna see if someone here knows if its hard bricked or soft.
Got root and had renovate rom 2.0 ( n7 port) then i wiped my phone and flashed renovate 3.3 (s7 edge stock)
my phone worked fine on startup and i started to restore my old apps through gmail. i thought it would take a while so put my phone in my pocked and let it be fore about 20 minutes then when i took it up it was complete dead. i had about 67% before it died i tried everything (vol up down home all together) for at least 15+ sec. had it charge over the night ( i noticed that the phone didnt get warm or any leds shown) in the morning i tried everything again and nothing. when i connect my phone to my computer i hear the connect sound and then it disconnect a sec later. if i hold power button down and connect it ( and dont release power) my computer recognize it as onyx8890 and if i release powerbutton it disconnects. cant boot it in any way whatsoever. so what do you think? its only a week old thats the worst part of it!
I have left it to the store I bought it from for warrantable but its still rooted and have a rom on it. well if its complete dead they cant see if its rooted so thats one good thing.
still want to hear you opinion
sorry for bad english
so, from what I understand, u cant boot into any mode, are u even able to see something on screen? (logo, boot screen, etc.) U can try JIG (it somehow make any samsung device go to download mode). otherwise idk.
Hi guys, I have the same problem with my S7 Edge.
Can anyone help?
OK. So I managed to recover my phone.
The phone was dead because of a software crash(nothing on display, no LED light, power+vol. down for reset not working) and when connected to my PC - nothing (just a connect and after 1 sec. a disconnect sound).
But if I kept the power button pressed without letting go, my PC would detect the phone as exynos8890.
I tried to keep pressing the power+vol. down while connected to PC and I realized that the combo worked because after ~7 seconds the phone would disconnect and reconnect itself (but still as exynos8890).
But I tried a different approach. While connected to the PC I tried to keep on pressing power+vol. down. And I could hear that it disconnected and reconnected. But I did not let go of the buttons. And again a connect and disconnect. And again. And after literally 5 minutes of the buttons kept pressed down without letting go and countless reconnects there was finally a change. The disconnect sound was not heard after the connect sound. At that point I stopeed pressing the buttons and when I looked at the phone I could see that the battery icon appeared. Since the phone was connected to my PC, after 1 min. the battery started charging (it was charged 31%). And after that my phone booted fine.
wow
Hi I have just bought an s7 which turned out to be a Korean G930L but I cant get any response out if it apart from the 2 bottom leds and and the blue one. No response from trying to get into recovery or download mode, basically a black screen though it does vibrate on what i think is start up. It is found by pc and Odin and charges ok, I can tell as I can see properties on pc. But no other response. Is it possible that the previous owner tried to root it using non korean rom or TWRP? Any advice on how to fix either getting TWRP on or screen to light up. I am sorry for being so vague I have pulled it apart and checked all of the connections, screen, motherboard etc but nothing. Or chuck it out or put back on eBay. I tried your idea but it only booted once in that 5 minute period so I tried without it plugged in and rebooted several times but still no screen response.
Hello,
As a newcomer to the forums, I'd like to ask for some help. I tried some of the methods described in several posts, to no avail. The situation is this:
Yesterday, I forgot my Defy+ on my desk and the alarm went of at 21:00 as programmed. It went for about 30 mins after that it was cancelled by default. I switched the wifi on and the phone restarted. In fact it stuck in a restart loop, mostly with the Motorola logo on screen. I took the battery out, kept it for like 30 mins, popped it back in and it went to the recovery console with the exclamation mark and the little droid icon. It stayed there for 30 sec, after that it went dark. Now this happened before so I did not panic and tried the battery swap again.
However, this time the phone is silent. Dead. If I plug it into a PC it gives me the notification sound (like when you pull out a usb drive from your PC) and the battery still gives out 3.7V.
No reaction for pressing the power button or volume up/down or any combination of that.
My question is: Is there a way to revive my beloved phone or is it just a piece of history now?
Additional info: Yes, it was a stock Defy+ with Android 2.3.4.
Any help is appreciated!
Update
Update: When I plug it into a PC with the Volume- button pressed down, a white LED starts to light until I disconnect it. During this if I try to enter bootloader mode, the PC recognises it as an unknown device and immediately prompts me to reconnect it.
Any ideas?
Hello All,
Yesterday I dropped my phone and the power button got stuck. I opened the phone with my tools and was able to fix the button. I didn't power it off, I didn't think it was needed since the button itself has nothing to do with the electronics inside. While I was closing its back It suddenly turned off. I was very gentle, didn't do any fast or unsafe moves. Since then the phone shows no sign of life. I plugged the phone the my pc but there wasn't any sign of life either. The phone didn't show up on Device Manager or anywhere else. One time, I heard a connection sound but I am not even sure if it was because of the phone since the sound came like 5 minutes after I plugged in the phone.
I already tried pressing all 3 buttons for a long time but it didn't do anything.
So what do you think? What might have caused it? And can you help me?
Thanks
First thing i would do is tear down and disconect/conect the battery flat. After that, hold volume keys while conect to pc usb and see if you can get edl mode. Than flash all that has to be flashed with miflash and edltools.
