[SM-G925F] Hard Bricked, not turning on. - Galaxy S6 Q&A, Help & Troubleshooting

Hello guys,
My Samsung Galaxy S6 Edge (SM-G925F) has been sitting in the corner for a while. I've flashing it so Custom ROM (don't remember to which) and it got bricked. I've tried all possible ways to turn it on (Volume DOWN + Home + Power), but nothing helps. I can't turn on the Recovery Mode and Download Mode. I connected it to my PC, it recognizes it but instantly disconnects from it. When I hold POWER button, computer it recognizes it, when releasing the POWER button, it disconnects. When I open Device Manager on computer, it recognizes it as a Exynos7240. I tried to install various drivers but no-one seems to be working. The phone can't be detected by Odin, Multidownloader, Smart Switch and other apps.
If anyone knows the solution how to fix it, that might be really helpful.
Computer is using Windows 10 (64-bit).

[Q] Download Mode

OK, here is a question that has me stumped...I can not get my infuse into download mode. I have tried holding volume + - together and inserting battery, volume + - while inserting usb cable. I have tried several apps from the play store that are supposed to boot the phone into download mode. No matter what I try the phone boots into recovery, never download mode. I am not pressing the power button. I have taken the phone appart cleaned and blown out where the power button is, it looks clean, I can hear a faint click when I press the power button, it doesn't appear to be stuck as I can use it to power on and off the phone.
I am running paranoid android 2.0 from Scott. The same thing happens on CM10 and slimbean. I don't remember having this problem on CM9-I'm not saying this is due to JB at all, so please don't go there.
I would like to go back to stock and reformat everything, but I can't get into download mode.
Any ideas?
Thanks

OK. I got the USB jig, it works, I got my infuse into download mode, but my mac won't recognize it. I've reinstalled kies, tried different usb cables and ports.
I have enabled android debugging enabled under dev options, but I don't see where to enable mass storage mode.
The infuse shows it's charging from my usb port.
Any ideas?

[Q] SCH-S968C(GP) Hard Bricked

Greetings!
I recently rooted my Samsung Galaxy SCH-S968C(GP), and Installed CWM Recovery. I flashed cyanogenmod to my phone. It had issues so i decided to try another rom. I was attempting to flash GlamourS5 to my phone. I went through the process. When it finished, the phone shut down. It didn't restart like the installer said it would. So i pressed the power button- no avail. It is now thoroughly hard bricked. It does nothing when power button is pressed. When connected to Windows 8.1 via a Samsung Micro-USB cord, The status indicator light turns red, and windows indicates (beeps) that a new device is connected. Windows does not offer auto play options, nor does the device appear in the Devices and Drives directory. When I long press the power button, the status indicator light on the phone turns off, and windows indicates (beeps) that a device has disconnected. However, the phone does nothing else.
My question to you is: Have I ruined my phone permanently, or are there ways I can fix it?

S7 Edge stuck on samsung logo

Hello,
I have a problem with my samsung galaxy s7 edge. When I try to put it on the samsung logo appears for a second or two and then I see a black screen again, there is also written 'Kernel is not seandroid enforcing' in red letters in the left corner of the screen. Nothing seems to help, I don't know a lot of these android things, but I have been looking on the internet and i have tried a lot of things. First of all I've tried a hard reset (press and hold the power, volume up and home buttons), when I do this, I get the same screen as I put it on, but now there is 'Recovery is not seandroid enforcing' in the left corner instead of 'Kelner'.
Then, when I press and hold the power, volume down and home buttons and I click continue, my phone comes in download mode. I've seen a video about about a factory reset out of download mode so I thought there was still hope. The only problem is that I cannot connect my phone with my PC neither. My PC can't recognize my phone. I've tried to use different USB cables, I've installed USB Drivers on my PC, but nothing seems to help. I've tried to use ODIN, Smart Switch and Samsung kies, but they can't find my S7 Edge. There is also an option where you can enter the buildnumber and SN thing (idk) of your phone and I've tried that to. The only thing that happens is my phone who begins to charge and a sound on my PC that says that he is connected to a device, but he can't see him.
I really don't know what I have to do now, does somebody has a solution to fix this problem?
Thanks in advance.

HELP - Stuck in Fastboot

I have had my OPO for about 4 years and am currently running Lineage 18.1 with no issues. However the Power button on the phone stopped working and will not do anything. I inadvertently put it in Fastboot and cannot get out of Fastboot and reboot to normal. I have tried adb to see if I could do a reboot there but it is not detecting any devices. Before this incident the phone was unlocked, in developer mode with usb debugging set. Is there some other sequence to try. I have tried vol down and plug in usb, and vol up and plug in usb, and held vol up and down and plug in usb but none have worked. Any suggestions please.
Update: I just got Fastboot on the PC to reboot the phone. Yea. The Power button is shot. It has been in a case for years and I hardly ever use the Power button anymore. Don't know why it has failed, no abuse, maybe lack of use. Thanks anyway.
If I take the button out, does anyone know if the inner switch could be pressed with something to turn it on and off. I assume there would be somethin like that although I have not been inside one of these before. If I ever lose power on the phone I will not be able to turn it back on without the power button/switch.
