Phone was running LP Pacman rom and did fine for several weeksbut then started bootlooping for no apparent reason. Now it bootloops if I plug in the charger cable or hold down both volume keys or the volume down key even if I dont press the power button. If I press the power button by itself without plugging in the charger cable it doesn't do anything. When I take out and put in the battery the "SAMSUNG" logo come on momentarily but then nothing. I cant get it into recovery or download mode and Odin doesn't see the phone. I didn't drop the phone or get it wet or anything. Any ideas? does this sound like a hardware problem with the power button?

Hey guys wondering if anyone experienced the phone being basically bricked without actually unlocking, rooting or anything.
It has happened before one, just laying on the table and the phone turning off but it came back on after a while.
Today it occurred again but has not turned back on for two days. When charging the only light is the LED flashing constantly every second. If I hold the power button and volume up then the flashing of the LED changes pace to One long flash (1 sec) to two quicker flashing ones (.5 seconds). If I unplug it and plug the phone back, The LED flashing is back to the original constant pace.
When unplugged sometimes holding the power and volume up button initiates the LG logo and then turns off and then shows the logo once more and then turns off for good.
If I plug this into the computer, its like someone ejecting a usb and plugging it in like a maniac. I heard the connecting and disconnecting sounds from windows nonstop like as if its about to blow up.
I've tried holding the power button for a minute the same goes with different combinations with the volume buttons.
The only thing I haven't tried is opening the phone, kind of afraid I will mess it up. Any solutions?

Never heard of this but I can throw a few suggestions out. Try unplugging, then holding both Volume buttons and the power button (All three) for about 10 seconds. Try different USB ports.
Try this if all else fails: Source: http://cellphoneforums.net/lg/t348484-perform-master-hard-reset-lg-optimus-g.html#axzz2YPtvkfDk
To Perform a Master Reset via Hardware
1. Turn off your device.
2. With the device turned off, press and hold the Volume Down key as well as the Home key at the same time.
3. While both the Volume Down key and the Home key are held down, press the Power button.
4. When the LG logo appears, release all the keys.
5. Scroll to and highlight wipe data/factory reset by pressing the Volume Down key. Then press the Power button.
6. Scroll to and highlight Yes – delete all user data by pressing the Volume Down key. Then press the Power button.
7. As soon as the wipe has been completed, press the Volume Down key to scroll to and select wipe cache partition. Press the Power button when ready.
8. As soon as the wipe has been completed, press the Power button to select reboot system now.
9. The master reset should now be successfully completed and your LG Optimus G should restart.

What is your computer reading it as?
Sent from my LG-E970 using xda app-developers app
I have no idea, when I plugged it in and check device manager, its constantly refreshing as its connecting and disconnecting the phone very fast. Is there another way to check

Anyways, doesnt matter guys thanks for trying, decided to just go in att and buy a samsung s4
Hello,
I just flashed this rom: http://forum.xda-developers.com/z3/development/rom-zyxxos-5-1-1-v1-0-pure-stable-fast-t3229169
on my z2 (D6503). Yes, I know how dumb I am.
So the thing is, the phone won't boot.
Nothing happens.
No LED's, holding power button + vol up also doesn't work.
Red power button also doesn't work.
When I connect the phone to the PC nothing happens. It won't get detected.
Any idea how could I fix this, or is it hard bricked forever?
Update1: When I connected the phone to the pc and disconnected the battery from the mainboard the red light started blinking.
have you tried flashing a normal z2 rom?

Nothing works. No flashmode, no fastboot. It doesn't turn on. It's completely dead.
start the flashing process with flashtool and your phone disconnected
Hold Power button and the volume UP button until you feel your phone vibrate 3 times. Now its off.
when the program asks hold volume down and connect it to the pc/mac.
Hope this helps otherwise i dont know.

Guys, please read the post.
Nothing works.
Vol Up + Power button does nothing.
Anyway, I have access to battery so it's off for sure.
i have read the post and i am wasting time trying to help you. Though maybe you didnt hold them long enough..
anyway
try
pressing and holding all 3 buttons (power,vol+and vol-) all at the same time till it vibrates once then let go of the power button and vol+ but keep holding vol - while plugging in the usb cable this MiGHT boot your phone into flash mode
Have you make the phone works?? I am in the same situation! No buttons work, no power, no volume, no red reset, neither testpoint, when i plug it to the magnetic port screen shows sony logo, left for some minutes just let the phone overheat and no more! Plug battery out and turn off, but no more! Completely dead!
Samsung Galaxy S9+ No custom, Just a normal phone from T carrier.
The situation is as follow. I wake up everyday and cannot turn on my phone, the screen is black but I hear it beeping when i press the volume keys. I do a Vol down Power to restart thinking it will , it restarts but the screen is black and unresponsive no matter what I do, the Power button is still functional at this moment.
What I quickly did is I connected the phone to my monitor using USB-C and i have a mouse connected to the internal KVM of the monitor- , perfect got excited that the phone at least works, on the monitor it shows up perfectly, I can control the phone with the mouse, enter my 4 digit password, works. That was the situation yesterday. Should have backed up then but didnt.
Today I wake up, the Power button does not work, so I read and find out that I can go downlead mode which I did using the Vol down and Bixby and plugging the charger.
tried the Vol Down and Power to restart it does not, so again I go in to the download mode and accidently press Volume up, Now I am completely stuck on Downloading... Do not turn off target
1. Power button does not work- I have no idea how to get the past Downloading screen now
2. Would I be able to recover anything it its really dead?
3. Any tips?
i have this tablet which i think is bricked, it wont turn on even if i hold down volume up or down. when I connect it to the pc, after 30/60 seconds the com port appears (screenshot), after 1 second it disappears and continues like this. would anyone know what to do? flash a firmware? in the screenshots there are all the information of the motherboard
similar issues i had with my chinese tablets. The core issue i figured was that they don't hold charge any more and the battery drops like 20-40% with every restart. so the best way to get this up back is to put it on charge for few hours. then hold the vol up + power button, you should see the recovery mode/options page where when you press vol up button you can choose between 3 options of recovery, fastboot, normal. keep presessing vol up and go to normal and then press vol down to reboot into normal mode. if you have a different battery to replace, start there. Good Luck!
