There is a rare condition of the device where it can't be reset by a 10 second power press nor charged and appears to be completely dead. This somehow has to do with a low level Qualcomm debug mode.
If you happen to enter that state you need to press Volume DOWN + Power for about 2 to 3 minutes to reset the phone.

My Nexus 5 was drained off battery and was not taking charging suddenly. I entered the hard reset mode( power+volume down button) and accidently did a "restart bootloader". Since then my phone has been hard bricked! I cannot enter into recovery mode as well( power + volume down button). But I am sure that if I can get the bootloader running somehow, my phone will be back. I am sure it does not have any grave hardware issues as such. But the maintenance (service) center says , they will need to replace the motherboard, which is too costly for me.
Can anyone give me any pointers of how can I get my phone working again?

Have you tried connecting it to a computer and seeing if it gets detected by the computer in device manager? If so, it should still be possible to bring it back.
What exactly happens when you try to power it on? Does the screen turn on at all? Does it vibrate once, as supposed to, when you press the power button? Or is it completely unresponsive? Also, when you plug it in to charge, does a red LED light up where the notification light normally is?
Also, try various combinations of powering up sequences. You want to try the following:
Hold power
Hold power + vol down (this should bring you into bootloader)
Hold power + vol up
Hold power + both volume buttons
Let me know what happens when you try this, and maybe I can help you out!
Hi I need help urgently. I wanted to boot my phone into recovery mode so i after i switched the phone off, i pressed the power button + volume up. My phone was connected to pc all along. problem is, i removed both my fingers off the power and volume up the moment i saw the "OPPO" boot logo, and realizing that the screen is blank, i removed the power cable connecting my phone to the pc. Now, my r7f refuses to boot.
Weird thing is when i connect my phone to the pc, sometimes the pc recognizes an unknown device thats "malfunctioned". This is called 'bricked'? How do i solve this?
I cant even switch on my phone or remove the battery due to its built-in battery. had 70+% battery at the point of occurence.
My R7f goes into the fastboot mode when i hold the power and volume+ . I usually enter to the recovery mode by holding the power and volume -
You have to hold the buttons for more than 2-3 seconds even the boot logo is shown keep holding them.
I have a Lg G Pro 2. Few days back it got bricked by its own( a crazy fact). That time it was showing QHSUSB_BULK. I figured it out as 9006. Took the phone to a local service shop. Today I got it back and found that nothing had happened to the phone, except worse. Now it is not detected by PC, only green light blinks for some time if tried to power on. And then everything is black and cold as death.
I think it have been flashed with wrong ROM. Anybody here can guide me with the test points of Lg G Pro 2 (D838 F350) ? So that I can force it to QHSUSB_BULK ? Or any step by step advice to get it up ?
I am in real need of assistance, and thanks in advance for any sort of help. Best Regards.
I would like to mention that the phone indicator blinks for sometime if I try to power it on, as it does on boot, but nothing else is there. No recognition by PC, no presence in Device Manager. Blinks for sometime, stops, again starts blinking... and this goes on at regular short intervals. The area around the camera gets warm after sometime. Everything loops till I pull off battery.
Now, am I missing something ? Is the problem not as deadly as I am thinking ? Is it soft bricked ?
Hi, I not sure how it got bricked I never brick LG device.
Normally if anything happen we try pull battery out and put it back in, try then to turn the phone on.
Have you try connect to to pc with USB cable, one end of USB connnect to pc and other end connect to the phone. Then try press Power + Volume Up or Power + Volume down, this is to try to get into phone download mode. If you can get into download mode you can flash the kdz file to make it useable again.
Or without the USB cable we want to get to factory reset mode by use hardware method try press:
- Power + Volume Up or Power + Volume down
- If you see LG logo come up release the buttons you press above 1-2 second
- Press again Power + Volume Up or Power + Volume down
- Until it show and ask to use volume up/down button to select choice, say yes
Caution factory reset will delete all data on the phone and reset it as when you bought it new.
- Again it will ask for factory reset, use Volume up/down to choose and select yes for factory reset
turn on the phone and when light is blink press volume up or down button for some time and see if it it is detected as usbhulq?
Hello,
as stated, i got my power button broken probably due to water (not that waterproof huh?). The power button has worked for a few weeks, sometimes it was really sloppy and unresponsive, and stopped completely, and when my battery completely depleted i am now unable to power it on. I am able to get into download mode from where there is an option to restart the phone but of course it requires to press vol down + power button.
Have you got any magic tricks to turn on a turned off s10e with the power button broken ?
Hello! The solution: press volume down + bixby button and now plug usb c data cable (computer->phone), wait 3-5 seconds and phone starting in download mode. From download mode you can restart the phone with volume down button.
Hi,
I wanted to hard reset my OnePlus 8, as i do times to times to clean the phone (it's the first time on this one). But this time the simple manipulation that i did many times on my op5t, went bad...
just after holding power and volume down key, it goes in fastboot mode (same that the picture) and it's written this :
PRODUCT_NAME - kona
VARIANT - SM8 UFS
BOOTLOADER VERSION -
BASEBAND VERSION -
SERIAL NUMBER - (numbers and letters)
SECURE BOOT - yes
DEVICE STATE - locked
and the menu at the top scroll on its own between START/POWER OFF/SHOW BARCODE/RECOVERY MODE/RESTART BOOTLOADER, as if i was holding volume key.
When i hold volume donw or power key, it makes scroll stop but that's all. I try some things, as hold power button for a minute but it did nothing...
what can i do, except wait until the battery goes down to 0% ?
Thank you for you're help
Need to find msmtool for that device, try and scroll to power off, plug into usb 2 port and reset that way
I was able to shut down by keeping the power button pressed for like 3.5 minutes, weird for that was the only way to get out of it. I am on OS12 with is a mess by the way -Wondering which version of Android you have?
