Hiya!
The phone seems working properly except the LCD screen is black.
When I press the volume button I hear the beep noise and can receive calls.
If I put the USB cable windows does not recognize it. I see a device named 3 cdc-acm 4 cdc-ncm.
I have another S4 works great with the same PC so it is not a driver issue.
Can I fix that phone? DO you think it is hardware or software issue?
thanks
Volume down + home button + power button does not work

I can not get my power button or my call button to work on this HD2 I have been working on. Initally the phone had a bad motherboard but I am pretty sure the power button still worked on that motherboard. I switched the motherboard out with one that I knew worked but then at least the power button didn't work. I got the phone to turn on and operate so I did a factory reset and it will turn on fine now. But the power button and the call button don't work. I looked at the hardware again and saw that the ribbon cable to the buttons was ripped a little so I replaced that and still the two buttons don't work. I don't know where to go from here. The buttons do press down and click like the other buttons and I have made sure the buttons are lined up right.

which rom you flashed?
I have sort of similar problem where my screen also stops responding after a few minutes of powering on.
This is my very first post, so I hope you can forgive me for any mistakes.
I buyed an secondhand ZUK Z1 from eBay. Everything was fine and dandy.
But after a week I encountered a problem. Firstly the Volume Down button did not respond properly then it utterly stopped working.
I buyed spare parts (side key) from the official ZUK-Store.
These are the contacts to connect with the "motherboard"(?)
I opened the the Z1 and even replaced the side key contacts myself.
After putting everything back together and powering on, the Volume Down Button still didn't work.
Volume Up button and Power-Button works perfectly but Volume Down does not...
I can press the Button normaly and hear the *click* noise.
I guess it's either a manufacturing error or some Software detecting error. Or something burned up inside. Well I don't know.
I can't access to recovery without the Volume Key. So yeah... i'm pretty frustated.
I'm typing this to find others with the same problem and would appreciate it when somebody knows more.
The device is not rooted
ROM: CyanogenOS 12.1-YOG4PAS60J
Phone struck
I too have the same volume down key problem. Because of that the phone enters boot menu and it becomes very difficult to come out of it till the phone shows some mercy on us. Once by chance if it works then the phone works absolutely normal. But it is a potential problem.
Hi all,
I have accident on sea where one wave splashed a bag where my phone was. After small problems with "laggy" buttons everything went fine and my phone worked correctly except power button. It doesn't react. I couldn't even restart the phone. And when my battery was used I coudnt turn it on. I tried to press volume up + power button million times, or all 4 buttons, and somehow I manage to turn it on again while still I was on vacation. Few times I have entered Android recovery screen, and Power button worked perfectly there (I managed to press power button and select reboot device). And after the phone turn on power button would usually works few minutes and then it would died again.
I have installed software for simulation of power button and it worked ok. This morning somehow I decided to turn off my phone, and I couldn't even imagine what kind of problems I will have to turn it on again. Whole day I am trying to turn it on, but it doesn't react. When I pull in charger then it shows regularly battery status (70%). I am desperate :crying:
I am trying to google or find any solution how to bring it ON again without power button, but without success
Is there any way how could I turn Samsung galaxy S6 Edge Plus without power button?
And what you think, is this some kind of software problem, and maybe some factory reset or flashing might help? Or it is more likely hardware problem?
Many thanks in advance.
Can anyone help me?
I have just found this article which might help me:
How to turn ON Galaxy S6 without using the power button:
When the Galaxy S6 or Galaxy S6 Edge is turned off, press and hold the volume button for a few seconds.
While holding the volume button, connect the Galaxy to a computer using a USB cable.
Wait for your phone to boot to Download mode.
Then press down on the volume rocker to cancel the operation.
After the operation has canceled, the Galaxy will reboot and turn on.
You have successfully turned on the Galaxy S6 without using the power button.

But somehow this doesn't work for my phone? First I wasnt sure which volume button should be pressed, so I tried with both in all combinations and still cant get into Download mode.
But I am glad that samsung had created some workaround if power button is not working. THis used to work on older models I guess.
Is there anyone who might know the way how to turn on phone without power button?
Hello, some days ago my phone suddenly got black screen, the buttons light ON, it also vibrates, if i double press the home button it enter the camera because the shutter souns, led notification also lights, seems like everything work but the screen keeps black..
I tried sme of the method around the web:
Power button + volume down (FAILED)
Power button + volume up (FAILED)
Power button + volume down + Home (FAILED)
Power button + volume up + Home (FAILED)
Delete cache (FAILED)
Factory Reset (I THINK IT FAILED, IT WAS HARD TO ENTER TO RECOVERY AND SELECT FACTORY RESET SINCE THE SCREEN DOESNT TURN ON)

Fast fast try to return it before Trump wins . He will build the wall you know... Jk...
For my opinion LCD has to be changed. Due drop or in your pocked from high pressure i think its gone ...
Since as you said phone is working you can take pictures or receive calls but screen is always black.
Can you see its black color or screen isn't turning at all.
Sent from my ONEPLUS A3003 using XDA-Developers mobile app
Mine started with green stripes allover the screen and few days later - "black screen"
Samsung change the whole unit.
But if lcd doesnt work so, it wont recognize when i press the screen, can it?
Anyone with this problem

S7 Edge BSoD Extra Info. needed
Hi,
Phone: I have a Samsung Galaxy S7 Edge SM-G935FD
I was using my phone to send a txt (and at the same time I think I was receiving a text or call because the menu and back touch buttons were lit up) and all of a sudden the phone crashed as I tried to finish my text but the touch wasnt responding, then the backlight turned of like it does if the phone is not being used. But the strange thing was that the menu and back touch buttons stayed lit up (Solid).
I tried many methods to restart the phone:
Power button + volume down (FAILED)
Power button + volume up (FAILED)
Power button + volume down + Home (FAILED)
Power button + volume up + Home (FAILED)
So I thought I'll let the battery die and then recharge and hopefully the phone would automatically restart like normal, however the phone does not show sign of charging now.
So I tried to connect to the PC but it wasn't being recognized however when I press and hold the power button a sound of detecting a device sounds and then when I take my finger off the sound of detaching occurs. But I couldn't see anything happening, until I went into device manager, under "Other Devices" , "Exynos8890" appears which I know is the chipset.
This is as much as I know of the problem. How do I solve thins problem without trying to factory reset the phone and lose all my data?
PS: I didn't backup my photos (My baby children only copies) or Notes in NotePad, which has some very important info.
Hello guys,
Hope someone is able to help here.
I got Yotaphone 2 YD206 to my hands. It has problem with front screen staying always black. Rear screen says "Turn over the phone to set up". Cannot do it as front screen is always black.
Volume buttons work and power too. Also the phone rings if someone calls me. I can shut down long-pressing power button but device always restarts. I cannot enter download neither recovery mode. Power + VOL down or power + VOL up always reboots the device back to "Turn over the phone set up" -screen (text in rear screen).
I have flasher and Lollipop firmware files. But flasher says <waiting for device>. For me it seems issue with drivers. I have tried several usb drivers (WIN10 laptop) but still no luck. ADB devices command doesn't show any devices connected.
Any ideas? I believe someone might have a trick I have tried yet.
Thanks in advance!
Edit. After fighting hours and hours with flashing I decided to open the phone and found it was just simple hardware issue. LCD flex was disconnected...put it back and phone is alive.
