my lg v30 plus suddenly blackout but phone is working all calls notifications sounds are coming. there is no prior sign of any problem. nothing feels in darkness, battery disconnect and connect again no sign appear even of charging or logo or download mode etc. i reconnect the LCD cables but all in vain
any suggestions please
most important is that i charge my phone the battery is 32% and about after ten minutes i disconnect it not see what is the position and put it in my pocket after one hour i found the phone blank screen
Just now my V30 had its first total screen blackout. I logged on here prior to checking whether anything was working (tried hooking up USB-C charging and Qi charging; phone would have been on silent mode so I don't know if calls / notification were working, didn't bother checking any Bluetooth connections etc.).
Anyhow, the fix was long press volume down + power button for about 10 seconds. Power button alone wouldn't do it. Back in action.
tried button combination but nothing

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
Screen keeps on turning on while charging & sometimes Power Button on phone wont work
For some reason, while connected to bluetooth, the watch's screen will light up and show on the top that it's connected to bluetooth (as if I slided down). Right now I disconnected the bluetooth and it's charging just fine. Also while connected to bluetooth, sometimes the power button on my Galaxy S5 (running AllianceRom) will become unresponsive. Any suggestions as to how to fix this?
Lastly, I had uninstalled the stock email app when I flashed the ROM months ago, but when I go to my old apk's to install it, it won't install. It'll say, "App not installed". How can I get it to install?
Hi,
My phone has a faulty power button and I'm unable to get it fixed. I've found easy work-arounds for it for locking and unlocking the phone. However, I'm not sure how to turn on the phone if it's switched off.
When I connect the charger, even if the battery is 90% it won't turn on on its own...

Nope, the only way I could turn it on was to open the back cover (very painful process) and then press the button area with a pin.
Couldn't get it fixed, so I had to change the phone.
I think there are possibilities in rooted phones, but otherwise the best thing to do is to keep a battery alarm at 30% or more, and keep it on charging whenever you can to avoid a power off. In power on, there are many ways of locking the screen in the MI UI.

Thanks. I installed Blocco Schermo - Simi Studio v.3.21 , a simple app to lock the screen...and when i flagged the option "show in notification area" , the problem magically disappeared.. The Power On/Off button started to work again. I think it was an hardware problem (because the problem has come up after the phone was at the sunlight for hours in my car and went very hot) but now i think it's obviously a software problem.
Hi guys, I got the same problem too. Unfortunately, I drained my batt while playing games. So the problem now is I can't turn it on. Any idea how to turn on the phone without using the power button?
I solved it
Hi guys i solved a problem! You should hold main button + down volume button for 10-20 seconds. Then, when MI Remote opens, stay on the reboot and wait about 3 minutes, then stay on the reboot systems as well. Great work!
just change the volume flexible. its also not took much cost.
I've just dropped my RN4 and the screen stopped to work (black screen with no backlight) but I could tell that the touch was working well as I've managed to pick up a call. I wanted to remove the SIM card from the tray so I turned the device off by pressing power button for approx. 15s. Then I wanted to back my data up and boot the device to transfer data to the PC however I was unable to - when I've tried to press the power button to turn it on, device vibrated once and is doing so repeatedly from then on (the cycle is: vibration - 10 s pause - vibration-.... you get it). After plugging it into PC it is discovered as unknown device only. Is it matter of broken screen only or some more serious problem?
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?
