unable to power off phone (down vol+power), stuck at logo "Fastboot Mode" screen - OnePlus 7 Pro Questions & Answers

unable to power off phone (down vol+power), stuck at logo "Fastboot Mode" screen
Unable to power off phone (down vol+power), stuck at logo "Fastboot Mode" screen, tried installing Android 10, stuck in a boot loop to fastboot, went to fastboot twrp 3.3.1-70 and now hung completely. Any suggestions my fingers are getting marked from holding buttons with no results. Luckily the phone is at 99% battery right now (I did not mean that as draining battery could take days not good for teh screen either), I hate not having a battery to pull to fix these issues, not getting worried right now.

Apparently vol+ + power does work took maybe 40 seconds, not sure why searching returned vol-

Moto G wont charge in Rom - Fastboot works

I've got a XT1032 with CM11. I already tried other Roms. I cant charge the Phone inAndroid or TWRP. Only in bootloader. Fastboot works, too.
I tried different charger. ADB or phone connection doesnt work.
Anyone an idea.?
EDIT: Also charges, when off
Nearly same situation was on my Moto G yesterday.
But with one difference, mine is stock.
It was charging but when i tried to power up, moto boot logo was appearing, globe was spinning but at the 3rd image (something like train or farm plant) it was giving up and screen turning black, and this loop kept on until battery completely discharged.
I hold the vol down then pressed power button and kept holding them about 10 seconds and released both of them.
Fastboot menu showed up, i scrolled down to recovery with vol down button and selected with vol up button.
A few seconds later an android robot showed up with an exclamation mark in its stomach.
And i pressed and holded vol up button about 10 seconds then while holding vol up button pressed power button once (still holding vol up) and recovery options showed.
I selected factory reset option and rebooted the phone.
It booted normally and running fine now.
Maybe this methode work for you too,
Good luck bro.
Doesn't work for me. Flashed it several times with different ROMS and Kernels. No change. I would say the USB Port is defect, but why can I use Fastboot and charge the phone in fastboot mode or when it is turned off.

Stuck in bootloop, can't get to recovery

I have a Moto G XT1034 that is stuck in a boot loop. I am not able to get to fastboot or recovery, it just keeps rebooting over and over again. It started at about 50% battery, now it's at 0% even though it's been plugged in for most of that time. This device has an unlocked bootloader, is rooted, and has been running kitkat for almost a year. Nothing that I can think of has changed today.
Things I have tried:
Holding vol up + vol down + power for 4 seconds
Holding vol down + power for 4 seconds
Holding power for 120 seconds
Letting the battery drain completely, and then plugging it in. It just starts with the reboot cycle again.
Any ideas?
That doesn't seem right. Try holding volume down and power for longer than 4 seconds.
Here's a video of me holding vol down + power for 120 seconds, as advised in Q28 of this sticky. Doesn't get me to fastboot.
I have a second moto g here, and have swapped the batteries, so the broken one has a fully charged battery. The bootloop continues when fully changed. Video here. Holding vol down + power for a few seconds, or 120 seconds also doesn't do anything when fully charged.

flash costom recovery....using adb fastboot command
Thanks for the replies.
I am not able to power it off. I have found two ways of "powering off" which are to either let the battery drain, or to hold buttons during the black screen part of the boot loop.
If I wait for the black screen part of the boot loop, and quickly press vol down + power, it will stay black as long as I'm holding those buttons. If I hold them for 4 second and release, it then enters the boot loop a few seconds later. If I hold them for 120 seconds and release, it does the same thing a few seconds after releasing.
I am not able to open an adb connection to the device. "adb devices" shows no devices in all phases of the boot loop.
To predict future concerns, I have the proper drivers, and have used adb quite a bit to work with this device. Also I can use adb on the second moto g with no problems. So my pc is set up and configured correctly.

Try this topic and see if it can help you:

Just remember to acess it when you have time to do all the tutorials that I've linked. Doing it with attention probably will solve your problem;
:good:
BobDiaz thanks for the suggestion. I still can't get to fastboot though, so this never does anything other than "waiting for device" If i plug in my second moto g, of course, then mfastboot works fine once I boot into fastboot.

in black screen you must do vol+power process 2 times..... first time nothing happen... in second time you press the power+ volume down the fastboot menu is shown...
That's very strange. Makes me think there's a hardware problem. The only point I can mention (sure you've tried this, but just to be sure) is to keep it simple: if your phone doesn't reboot after holding the power button down for about 10 seconds (with or without pressing the vol down button), then you almost certainly have hit a hardware issue. Especially if you've taken the lengths of swapping batteries and not seeing a difference.
I know that with my 1st gen Moto G, when I'm stuck in a boot loop after too much mucking around, I just hold vol down and power for ten or so seconds, and then it boots into fastboot mode. That's how the phone was designed. Best of luck.
Correction: the phone shuts down in just over ten seconds, and when it does I let go of the power button but continue holding the volume down key for several more seconds before I reach fastboot. As well, since I'm about to use fastboot, I've always got my phone plugged into USB when I do this. But, I just tried it unplugged, and it worked the same.
Try pulling the battery then holding up on volume and power button and home same time

Hi TracvisTx, T
I just ran into exactly the same issue as you have mentioned here.
After doing downgrade from Lollipop to Kitkat, my moto g is stuck at bootloader warning. It power on's, gets stuck on warning, reboots. Does not charge to more than 0%.
I was wondering if you could come out of this issue and how? I am also unable to enter into fastboot mode! I have tried all the described combinations of power + vol (up/down) buttons.
Please help.
Thanks,
@beerbarfly - Hold vol down (or up) while turning on wall charger.

You said the phone is bootlooping - hold vol down (or up) immediately after reboot.

lost101,
The screen blanks out, then it shows battery charging (0%), then goes to "bootloader unlocked warning" and then back to black screen.
In all this, even if you keep vol + power buttons pressed, nothing happens.
Infact, if it is in blacked-out screen step, and i keep these buttons pressed, it remains in black-out, does not even go to charging screen....
Looks like that is what is called as bricked phone

Only hold either Vol up or down - forget about power button.

Is there actually a way to Power Off the OP7? (rooted with Magisk)

My new rooted OP7 seems to be going well. Continuing with the set-up and doing back-ups every few steps.
One things that puzzles me is that I cannot power off the phone. When I select "Power Off" by long-pressing the power button, the phone goes to the screen that says "The boot loader is unlocked (…)" — at which stage all I can do is Volume minus/plus + Power, which reboots the phone.
If I go to the Bootloader and select Power Off, the same happens: the screen that says "The boot loader is unlocked".
I rarely switch off my phones so it's not a huge problem, but wonder if this is expected behavior on a rooted OP7.
Thanks in advance.
Hi! To power off your oneplus 7:
1: Long press the power button just until you feel the vibration (Without turning the phone off). About 2 seconds.
2. On the right side of the phone screen, there will be a vertical popup that gives you the option to a. Power off, b. Restart, c. Recovery, d. Bootloader, e. Screenshot.
Press a. Power off.
That will power that baby down.
(I am not sure if this is also your question, but I am writing it anyway ?). When powering on or rebooting the phone and you come across This Screen You Mentioned: "If I go to the Bootloader and select Power Off, the same happens: the screen that says "The boot loader is unlocked".
Do nothing, absolutely nothing, and the phone will boot normally.
I hopsies that answered your question.
Hey there!
Thank you for your reply.
What I was trying to say in my first post is that when I select "Power Off" from that vertical bar you mentioned, the phone does not power off, it goes to the screen that says "The boot loader is unlocked".
But actually, tried it again, and this time it did power off.
Maybe it's fixed!
My set-up is nearly complete.
Backup backup backup.

I don't know how to fix your issue but I can say that my Oneplus 7 is also rooted with magisk and it does not do that. Although when I try to charge my powered off phone it gets stuck on the bootloader unlocked warning screen until i reboot it with power button + vol up.

I think that's what I'm noticing:
- when the phone is unplugged, it's possible to power it off
- when the phone is plugged in, it's impossible to power it off (gets stuck on the screen that says "The boot loader is unlocked (…)", at which stage it's Volume+/- && Power.

It does not matter if the phone is still charging when it is in this state. But is it really charging ?
Everyone stop!!!!!!!
The Bootloader is Unlocked warning screen is Normal when rebooting the phone.
When it boots to that screen, Don't do anything.
Your phone will boot normally after it is done "warning" you that the phone is unlocked. It will do this after every reboot if you unlocked your bootloader.
Again, if it boots to the bootloader unlocked warning screen, Don't do anything.
It will start Normally, if you leave it alone.
This is Normal.
Again, Don't do anything when this screen shows up.
Your phone will finish booting afterwards and then it will show the boot animation and then it will show the lockscreen.
Again and again, you Do Not need to do Anything when this screen shows up. This is normal, your phone will boot after the warning screen goes off (about 1 min to 1 1/2 min).
Again and again and again, you Do Not need to anything when the warning screen shows up.
There is nothing wrong with the phone.
This is completely normal. (Although, that's what they said about puberty too...:cyclops

Completely Drained Battery "Battery is too low" Boot Loop, Not Charging

I completely drained a OnePlus 6 (6 gb) running Lineage OS 18.1 with Magisk root. When I plugged it into the OnePlus charger that came in the box, it started to boot loop, showing the 1+ logo, the unlocked bootloader warning, then "Battery is too low" warning (red text, different languages), then shutting off to repeat that. Sometimes it would not do the "Battery is too low" warning.
I've left it to charge for 2 hours now with no luck. After a while it stops boot looping then just stays black. When I click the power button once it shows a charging screen, a circle with a lightning symbol and shows a charge going into the circle.
It does not boot when not plugged in.
When I try to boot it and it goes onto the 1+ logo screen or any screen, then I unplug it, the screen will completely turn off.
I've tried to access fastboot mode and change chargers but both don't work. Holding the volume button and power button just starts the boot loop from a black screen.
Is there anything I can do to fix this problem? Or another forum that might have a solution? Thank you.
Edit:
I am able to get it into fastboot mode, but I cannot boot into twrp through "fastboot boot" or from the recovery mode option.
When I use "fastboot getvar battery-voltage" I get either 4329 or 1802.

Oneplus 8T bricked after dying last night

Was watching youtube videos last night before my phone died, now I can't get it to start boot into the OS. Not sure if this is relevant but my power button had been a little finnicky- rather maybe not the power button itself because it doesn't feel stuck or anything at all but I noticed that it would take an extra second or two after pressing the power button to get into my lock screen. I never really paid attention because it only happened once in a while and I would just restart my phone and be done with it. However I can't even get into the lock screen or anything now.
After my phone died last night I plugged it in right away and came back a while later to turn it on. I tried turning it on but noticed my phone just kept rebooting. It's still repeatedly rebooting and I can only get in the fastboot menu by holding down both volume buttons when rebooting. I get the options power off- which just reboots it after a while, start - which just reboots the phone, restart boot loader- which literally takes me back to the same menu, recovery mode- just reboots and show barcode which shows the barcode at the bottom of the menu.
I've tried downloading the qualcomm driver and trying to get into EDL mode but don't see it on my pc or msmtool, i'm also not even sure if i'm trying to get into EDL mode correctly. I've tried disable Driver signature Enforcement and then redownloading the qualcomm driver but still no luck. I don't know what else I should try. Someone please help me out, i'm pissed this happened just because my phone died, about to have ptsd whenever my phone is at 5% fml.
Also after seeing the 1+ logo and powered by android on the bottom, sometimes I would see like a line of color, which I would assume is text not being rendered all the way, fade out and then the phone shuts down and reboots itself.

Which OOS build are you on? And your device is unlocked or not?
Getting into EDL mode is tricky. Power off device completely. With the device powered off, hold down volume up and volume up at the same time, keep them pressed all the time, and during that time plug into PC (phone all the time powered off). Still hold both of the buttons. By the time you plug into PC, you should be in EDL mode, BUT it only lasts about 10 seconds. I mean you have to click start in this 10 seconds time bracket, other way phone exits EDL itself. After you click start, you can release button, obviously
