Samsung Galaxy S7 home, volume & power keys not working after flashing ROM - Android Q&A, Help & Troubleshooting

Hi all, yesterday after rooting and flashing TWRP I decided to put the Pixel experience ROM onto my phone.
Now my volume up, volume down, home button& power button don't work.
I used a keylogging app and found that all the keys are showing up as pressed & when checking the keymapping in General.kl all the scancodes are assigned to the correct keys.
I tried using a button remapper to assign the buttons to themselves but when using that; the buttons showed up as 'Unknown'
I've been using my battery case to wake the screen & the multitasking to go home, but this is a real nuisance!
I am also able to power my phone off by holding the power and volume down, I've been using this to wake the screen (restart phone) but the power button doesn't work for waking the screen

How to simulate power button with volume key(up and down at the same time)

Hey guys. So my wife's i777 power button just died on her. And to fix it I am thinking of using the volume buttons (press up and down at the same time) to simulate as if I am pressing the power button. Is there any such fix ?

Click to expand...
Click to collapse
CM and AOKP roms have an option to wake the phone by holding volume down.
Also you could download Gravity Screen Off which is a pretty decent app for getting around this problem as well.

How do I Power on my Android Smartphone without Using the Power and Volume Button?

I have an Android smartphone that I currently cannot power on past the charge screen... The power and volume buttons are broken.
How do I power on the device to get to my apps, home screen, etc (past the charging screen)?
Can I use the other smartphone that I have to access the phone with the broken power and volume buttons?
Thanks

GApps error after installing Phone no longer starts.

Hi all.
I have a phone Samsung 920I not "L"
OK to start from the beginning. I am new to this and followed steps from watching Channel48 on YouTube. Not blaming him it's just so you have an Idia of where I got my info from.
Instlled Odin
I installed twrp-3.1.0-0-zeroflte.img and it didn't work.
I then found twrp-3.3.1-0-zeroflte.img and installed it over the top, Now works when booting into recovery.
I then installed 920F Samsung recover file that was only about 25Mb in size and got my phone working again.
left it for a day then tried again.
Installed twrp-3.3.1-0-zeroflte.img with Oden. works
Installed: EvolutionX_4.1.69_zerofltexx-10.0-20200331-0232-OFFICIAL Works I was happy Looked at "About" and it now says my phone is 920F :/ Andoird 10 cool it works so who cares if it says 920F right!!!
I then booted back into Recovery and Installed: open_gapps-arm64-10.0-pico-20200228 and that said it successfully installed and I swiped to restart the phone.
My phone powered off and that's where this ends.
I have tried holding the power button for about 30sec and nothing happens I tried plugging into the charger and it doesn't respond to show it's charging
Is there something I can do now or is the phone dead This is my main phone as I love the Samsung S6 over the rest because it has the main buttons, not on touchscreen and IR so I can use the phone as a remote.
Thanks
edit. update
I got my phone working again. I will leave this thread incase someone else asks the same thing.
How I got my phone to work again. This is what I found on Google search and I will BOLD the option that turned my phone on.
Press and hold Power button for more than 20 seconds to check whether it turns on your phone or not.
Press and hold Volume Up button for a few seconds and without releasing the Volume up button, press and hold Power button until your screen displays something.
Press and hold Volume Up button for a few seconds and without releasing the Volume up button, press and hold the Power + Home buttons until your screen displays something.
Press and hold Volume Down button for a few seconds, without releasing the Volume down button, press and hold Power button (totally 2 buttons) until your screen displays something.
Press and hold Volume Down button for a few seconds and without releasing the Volume down button, press and hold Power button + Home button until your screen displays something.

Power button doesnt work but volume up acts as holding power button when holding it

My mom's tablet is having some issues recently, but the most important issue is the power button. We thought its broken/doesn't work, but it somewhat worked when press and holding the volume up button when increasing the volume. It shows the Power options, same when press and holding the power button. Is there something wrong within the buttons? How can I fix it?
btw the other issue is the memory overflow restart issue when the tablet freezes, then beeps for a long time, and finally reboots. Any fix for that, too?
Anyone?
