NEED HELP - Can't turn on, strange problem! - Nexus 5 Q&A, Help & Troubleshooting

Hello, i bought a NEXUS 5 off of a guy, who said that he plugged in the charger and went to sleep, at the morning the phone was dead, no reaction etc. I tried pressing power+vol up, nothing happens, power+vol down, nothing happens. Then i plugged it to my PC and when i press power+both volume buttons, the pc recognises a "Quectel QDLoader 9008". When i charge, no lights come up, i tried those power+volume combinations and the screen is not turning on even for a second. Only the thing that i can do is plug to pc and power+both vol to get it recognised as "Quectel QDLoader 9008".
Any help would be appreciated!!!

I just disconnected battery and reconnected it, now it does like that:
I hold power button
windows shows unknown device malfunctioned
nexus 5 screen is black, no signs of life

Seem like Bricked :/
But it can be fixed as far I know with fastboot flashing

Just flashes on startup. Black Screen

I got an HTC One S from a friend who got it from another friend. I don't have any history on the device. He gave it to me to fix because I'm the only Android user he knows and his phone won't start.
If I keep the power button pressed, the capacitive buttons flash exactly 15 times and occasionally the phone vibrates. I don't have a One S so not sure if that indicates that phone was started or shutdown.
Neither fastboot devices not adb devices shows the device. But every once in a while when it vibrates, if the phone is connected to the PC with a USB cable, it beeps - like it's connected. I don't see Android Phone in Device Manager. But I see a MTP USB Device with a yellow exclamation mark. Uninstalling and reinstalling HTC Drivers didn't fix the problem.
I have tried Power+Volume Down key. Shining a torch on it (seemed to work for a few people), keeping it plugged into the mains for 3 days, kept it in the freezer for 2-3 minutes (also seemed to work for one person).
I think when I first got the phone and plugged it into the mains, I saw a red charging light. But I may be mistaken. In any case, there is no light anymore indicating charging. But I don't think that's the problem.
I have no idea whether the device is bricked or not. And if there is any way to fix it. Samsung has Odin which makes any Samsung phone practically unbrickable. I haven't used any HTCs since the G1 so have not been in touch too much with the HTC development. But from reading, it seems that messing around with Romming with S-ON can cause the phone to be bricked. And perhaps that's what my friend or his friend did. Does this sound like that's what could have happened?
Thanks for any pointers.
I dont think the device is bricked. its just a little harder to press the power and volume down when you see the buttons flashing.
just check and do these steps.
connect the mobile to charger and see if the orange light comes and stays on
if the orange light is there, press the power button and keep your finger ready near the volume down button
you should keep the power button pressed and as soon as the orange light disappears you should press the volume down button until you end up in boot loader screen
give this a few tries and see if the device boots up in bootloader

The problem is that I no longer see any light at all when I connect the phone to a charger. It's probably fully charged. Would that show a green light? If so, that's not visible either. I have a feeling that the bootloader has got wiped out or something.
I read in one post that the phone may be stuck in the QHUSB-DLOAD mode.
So I followed the steps in http://unlimited.io/qhsusbdload.htm. But that didn't help. I don't remember the exact statement since I was running an Ubuntu Live CD. But the gist was that it couldn't connect to the phone so presumably it's not stuck in QHUSB-DLOAD mode. Although the site states that it will NOT fix QHSUSB_DLOAD issues encountered by flashing ROMs - which may well be what may have happened.
I understand that running an RUU for the HTC One S may set it back to factory state. But for that I need fastboot to work.

[Q] Bricked or hardware damage? OPO not turning on

Hello OPO-owners.
I need some help. My OPO won't turn on. When i press power nothing happens. When i plug it in it vibrates one time, the screen turns on staying black (only backlight) then the screen turns a bit brighter but still black. Then the screen turns off and it starts from the beginning with one vibrate.
Booting into recovery with power + VolDown -> nothing happens
Booting into fastboot with power + VolUp -> nothing happens
power cycle - holding power 20 sec 5 times like suggested on oneplus HP -> nothing happens
holding power for a minute or more -> nothing happens
what i can do is boot into Qualcomm HS-USB QDloader 9008 by holding VolUp and plug into pc. From there i tried the unbrick method with color.zip. Msm8974downloadtool flashed the first two files then changed divice into HS-USB Diagnostics 9006 as it should and started flashing the partitions. But somehow my OPO keeps disconnecting in that 9006 state every 8-10 seconds so that the flashing keeps starting from beginning. then tried different flash tools found on androidbrick.com and finally managed to get it back to where it was by editing rawprogrammer64.xml to only flash partition table and recovery, rpm, tz, sbl1 and emmc_appsboot.
So now i'm right there where i started.
What came to my mind is, maybe there is something wrong with power button. As holding and pressing seems to do nothing. So when i try to boot into fastboot with power + VolUp and plug it in i end up in QDloader 9008 mode which should normally only happen when you just hold VolUp and plug in. Also something wrong with power button could also be the reason why it kept disconnecting in Diagnostics 9006 mode.
Has anyone ever experienced something similiar?
I'm gonna upload a video to show you what my OPO is doing when i plug into charger or pc.
After charging it for 24 hours I'm still where i started only that the screen is not black anymore but showing some stripes from top to bottom.
i keep on charging.

I just posted a bunch of my trial and error work at:
Post in thread 'Unable to enter EDL' https://forum.xda-developers.com/t/unable-to-enter-edl.4288003/post-86868743
So far my thought on the LED flashing on my phone is that it happens when there is a "power-up". So if the battery is dead or disconnected, I'll get a flash when it's plugged in. If the battery isn't dead and it's connected, I don't think it flashes, and I assume it has something to do with power already being provided.
The confusing thing to me is that if I hold the power button for about 10 seconds, while plugged in, with the battery disconnected, the LED will flash. Also, if I hold the volume-down button, it will flash about every 20 seconds. But it doesn't flash when doing either of those things while the battery is connected.
Does any of this apply to your phone?

Zenfone 7 pro stuck in Qualcomm Crashdump loop after successful display replacement

This started happening to me after changing a broken display. I get the asus logo, then the android one, then Qualcomm crashdump for less than a second then it repeats a few loops then shuts down.
I can put the device into fastboot mode by holding volume up + power but plugging a cable into it makes the screen flash and shut down and it does not get recognised by the PC. It also makes the phone heat up if left connected for a long time.
I tried making an EDL cable and putting the phone into EDL mode, but even that doesn't seem to work and the phone still isn't recognised.
When the phone is connected with a usb cable, no button combination will make it wake up.
Please help!
