[HELP] OnePlus 3T Stuck At Bootlogo - OnePlus 3T Questions & Answers

My OnePlus 3T got stuck on the bootlogo after I installed a few magisk modules. It will not reach the boot animation and so I can't get ADB to work. I need to get to recovery but I can't because ADB won't work and my volume buttons are broken. Any way to do this?
Edit: I'm running Android 10 and Magisk v20 if that helps at all.

I was thinking that it might be possible to use a USB keyboard to generate the volume up/down inputs, but I couldn't get it to work.
Without volume key presses I can't see how you can get back to recovery. You may need to use the unbrick tool.

Thanks for your response! I thought of that too but couldn't find my OTG cable so didn't get a chance to try it yet. From what I saw on the unbrick tool, it also required a volume button press. What I ended up doing was going to my local phone repair shop and hopefully when they get the part in they'll be able to fix it for me and I won't have to keep searching for an alternate solution as I don't think one exists. Thanks again for trying to help!

Get the volume keys fixed. The bootloader (what's showing the boot selection) does not know about (usb-)keyboards, in deed it does not know about usb (other then the fastboot mode). Anyway: good luck with your op3t!

Vol Up key broken?

So, my volume up key stoped working from one day to the next. Didn't slam the phone on the floor or anything, it just stoped working. I already tried it on recovery mode, no luck so i'm asuming it's not software related.
Anyone faced this issue at some point? I did the eb40 battery mod a month ago, didn't notice anything unusual since then.
Thanks guys for any help.
Anyone?
I'm worried i might need to enter recovery or bootloader using keys instead of software reboot at some point, and won't be able to since my keys don't work.
I mean you could open the phone and check the connection for the button and the contacts. Does it feel loose? Maybe the button is upside down ( which shouldn't matter but you never know). Get back to us!

And if is broken then flash phils advance recovery and you will never need it again. Lol

Wait what? I have the same problem (volume up key is broken) and I'm constantly paranoid about bootloops since fastboot reboot recovery doesn't work. I have Philz recovery as well. Is there some feature I'm not aware of?

The touch recovery does not require the use of volume or power button. Same with Touch CWM.

Oh. Well of course you don't need the volume key to navigate the menu in a touch recovery. That's not the problem. The problem is getting *into* recovery without the volume up key. The only way to do so is if you have a functioning ROM, so if you're in a bootloop, you have to FXZ back to stock from fastboot, reroot, and install a reboot to recovery app. Then commence doing whatever it was you needed to do in recovery (assuming flashing a custom rom again and hope you don't get a bootloop)

I understand now. Yes, it's tough to access fastboot or recovery mode without volume keys working.
Not at all there are ways to get around this. Install xposed framework with an advance power option and install it. Or go to play store and look for an app name i believe quick reboot

Indeed. I've wasted several development hours just getting back to a workable system when I end up with a bootloop. Makes testing very frustrating.Volume down key still works (it seems people only ever have problems with the volume up button) so can still get into fastboot. It would all be good if the "fastboot reboot recovery" command worked on this phone, but it's blocked.
EDIT: @Technofreak, once again that won't work if you're in a bootloop.

Yes, and fastboot only works while in download mode, which you can't access while on a bootloop.
mmm... is there any way to make the device boot into download mode by default? That would be maximum safety.
Btw, did your vol up key broke by itself? did you do the battery mod? Thanks for your input.

You mean download mode as in the menu where you can choose recovery or fastboot? You can't get to that without the volume up button at all. You should be able to still enter fastboot, even from a bootloop. Just hold down the power and vol down button until it vibrates, then let go. Then hit power button once more, and you should be in download mode. But that still won't get you into recovery, so you still have to FXZ back to stock from there and redo everything. There IS a way (sort of) to get it to boot to fastboot every time. Just flash an FXZ and unplug it while it's flashing system.img. Then manually flash a system.img. That should trigger the sticky bits deal where it boots into fastboot every time... but I really don't know what that will accomplish, because every time you reboot your phone you'll have to plug it into a computer and use "fastboot reboot." There isn't a reboot to recovery command in fastboot, and there is no option within fastboot itself to reboot, so you'd have to plug it into the computer and use fastboot reboot.
I wish there was a software option to always ALWAYS boot into recovery from a cold boot. That way you could always get back to recovery no matter what. FXZ is surely a last resort, but you can always restore a backup from recovery.
Yes, I have an EB40 battery mod. But the volume button didn't stop working until a couple of months after doing that. It was seemingly random. Just stopped working one day. I can't way whether it's related or not.

Mine did the same, broke down randomly after the EB40 mod. Can't check the frickin button since the black t5 screws got worn out (****ty quality).
What about fastboot update? isn't that suposed to flash zip files, as in cm zips?
EDIT: Been trying the vol down + power for a while, it behaves as normal power button, can't get to bootloader.

I have never been able to get fastboot update to work. I believe it is restricted on this phone just like fastboot reboot recovery is. Don't quote me on that as I've never seen anyone outright say that is the case, it just has never worked for me.
If it makes you feel better,don't bother trying to get the scews out. I have taken mine all the way down to the motherboard to see if there was anything obviously wrong with the volume button. Mine seems to have nothing physically wrong with it. The button (the bare button on the mobo, not the plastic piece) pushes well and even gives a nice tactile click when you push it down with the tip of a screwdriver or soemthing pointy. Hell, I've even booted it up with the case off, bare motherboard, while holding down the button with said screwdriver and it still won't work. It's got to be something like a trace burned or cracked on the motherboard, but with all the componants and shields around it I can't tell. It looks normal, and no different than the volume down button.
That sucks that you can't use the vol down and power button to get to fastboot. I just tried it myself to make sure I said it right and it worked fine. Maybe your volume down button doesnt work either??? You have to be very VERY careful if you cant get into fastboot. Don't get into a bootloop, because I don't know if there is any other way to recover at all. The only way I would know would be to short the circuit on the mobo to force the mobo to recognize a volume button press, and nobody wants to mess with that crap. Don't do any mods that are too exotic lol.
Vol down key is ok. Do you press both buttons while phone is off? For how long? This is weird.

Well, I believe the correct way to do it is to hold all three buttons down at one time, but for me just holding down the power and volume down button works. If the phone is on, just hold those two buttons down until it vibrates a couple times. At that point let go of the power button. Then press the power button again, and it should boot into fastboot mode.
If the phone is off, I would assume just hold down the power button and volume down buttons. Then let go of the power button while still holding down the volume button and it should boot to fastboot mode.

Good good. That will at least allow you to FXZ if all else fails. Just don't flash anything unless you have the time to FXZ back and do the whole process over, because in the event of a bootloop, AFAIK that is your only choice.
But we can always go to the recovery mode using the command prompt.
Connect the mobile to computer and use adb fastboot commands.

Once again, fastboot reboot recovery does not work on the Atrix HD. Let me qualify that, because there may be some people that it does work for, but the majority of us, the command is locked. In most cases, that is an invalid point, because we cannot get to recovery using fastboot.

HELP! I bricked my G2!

Hello, I am a NOOB, and...
I recently rooted my lg g2, vs9803aa, using the one click root, but haven't actually flashed any roms on it. I put autorec on to flash twrp, and also had titanium backup on there i was looking at to try to back it up. I restarted the phone and it is just blank screen now. I try the hard reset and it just buzzes in my hand once and no logo appears on the screen. When i plug it into the computer it generates a bunch of local drives that need formatting, and on device manager it shows as QHSUSB_BULK. I read in other threads that it matters what rom you are using for the possible fix, but i never got as far as flashing one, or recieved an OTA.
Thoughts please?! I really don't want to get a new phone, but at the very least for now I swapped the sim to an old phone, droid 4, for temporary use.
Thanks for any input.

Hi,
Have you tried download mode? If you dunno how to, here's how :
" press power button and select “power off”. Then, press the volume up button on your LG G2. While you are holding the volume up button, plug in your phone's USB cable. Keep pressing the Volume up button until the download mode is being displayed."
After you are in download mode, follow this guide to go to stock : http://forum.xda-developers.com/showthread.php?t=2432476
This should resolve your issue.

I get no screen prompts whatsoever, it stays black. I can hold the power button for a few seconds and there will be a single pulse of vibration, nothing else. It does the same if I hold volume down and power, as well as volume up and power. I even tried all 3 at the same time, same thing.

Let me make it clear. Turn off your phone. Plug your USB on your phone and press & hold volume up button and connect the other and of the usb to your pc.
Just had the same thing happen to me. Installed recovery through autorec and then upon reboot I get a black screen and everything else mentioned above.

I figured it out, as long as you don't mind wiping the device.
I used the SRK tool 2.1 to unbrick it. Link to post
After this I could get the LG splash screen again and enter download mode.
Then I used the LG Flash Tool 2014 to flash stock firmware back onto it. I actually downgraded to kitkat with the flash tool since it easier to root that way. Link to post

I messed up on rooting my Samsung Note 8 (SM-950U)

So I have tried multiple different ways to root my Note 8 SM-N950U. I've used SamFail with the different versions and before I started the process I forgot to enable developer mode, I know i know dumb freakin decision. I cant get my Note 8 to boot to anything whether it be with a rooted image or the original stock firmware. I need to know if there is anything I could do before I do a insurance claim on the device? any help would be greatly appreciated.

Could you press volume up bixby and power button for a couple second and factory reset?
I haven’t used the volume up button but I’ve down the volume down button along with the other buttons. Also the Samsung smart switch app doesn’t recognize the device, it says it’s unsupprted
Push all 4 of the buttons, volume up, volume down, bixby and the power button... For 10 seconds.... Then it'll boot up... Into another screen... Wait until it says volume up/volume down,.... Etc... Then hold the volume down and power until it reboots

Help (crazy circumstances) - Stuck in Safe Mode - Volume Down broken

Samsung Galaxy Tab S2
SM-T710 8.0" Wifi
Nougat with all the latest updates
Wife hands me her tablet the other day and it is stuck in safe mode. Using notification shade link to turn off safe mode simply reboots to safe mode. To make this worse, the other method of on/off safe mode is to hold vol down with power. It seems the volume down button has failed. When android is running, pressing volume up raises the volume as normal, pressing volume down does nothing. Same in recovery, volume up works, volume down does not.
Looking around for solutions, I stumbled on this:
http://forum.gsmhosting.com/vbb/f777/how-exit-safe-mode-samsung-phones-simple-solution-here-1727011/
which claims to allow safe mode disabling with root. Ok, so I figure I need to root the tablet, no big deal. Well I'm stuck, I can't get it to work.
I've follow every guide I can find. Most all of them start with rebooting to download mode. The standard method is to hold volume down again, can't do that. So instead I use adb (adb reboot download). The use Odin to flash TWRP - no go. Every instruction I can find also says to hold volume down after Odin finishes the flash. Just powering off, and then holding vol up + power + home doesn't get me anywhere. I can boot back to android, reboot recovery, and it is only the stock. Even tried flashing a nougat (supposed) version of CF autoroot. That does something more, because the boot screen warns me that SE Andriod is not enforcing. But even that simply ends with rebooting to Android, no root. Interestingly, the last step in the CF Autoroot says "Restoring Stock Recovery", not sure why.
Ok, so there it all is. I'm stuck. Anyone have any ideas
a) how to get safe mode off with no vol down button
b) how to actually successfully root the latest nougat (again, with no vol down button)
Any ideas are much appreciated. Thanks

I doubt it's failed. Your volume down button is probably just stuck down which is why it continually boots to safe mode.
Volume up would still work.
Pop the back off and check the contact under the button isn't stuck down or get the vacuum cleaner hose with the slim attachment , place it over the button and it MAY just be enough to release it.

You could be right. Wouldn't know it by the feel of the button. It feels perfect. And being in safe mode won't let me load any app or anything that might tell me one way or another.
I'm trying to avoid cracking the tablet open because I'm not sure I'd be able to fix it at all once I did. Probably can't physically see any issue it might have with the button. Plus it looks like a royal pain to open. But in the end I might be forced to try.
Anyone know a root method that doesn't involve volume down?
Terrible to think that the whole device could be rendered useless by a button that isn't critical to its use. (can turn down volume by hitting vol up and then using the slider on screen)

You can get root no problem just by flashing a rooted Magisk boot image, but I doubt going to help with booting into safe mode as that button combo is hard coded.

Well if root does not allow disabling of safe mode, then I'm out of luck. But this link indicated that it could work. I've never tried so I'm just grasping at anything.
How exactly can I install a rooted boot images without the following:
- No ability to install a playstore or any other app (no magisk manager)
- Can't get TWRP to install (presumably because this is now blocked by latest firmware?? Not sure but it fails for me following the Odin instructions I find here and elsewhere) I think this requires vol down button - at least all the instructions call for it after flashing TWRP with Odin
I have ADB and Odin at my disposal, but I can't seem to get Odin to actually install TWRP. CF Autoroot (for Nougat) does nothing either.
Am stuck in safe mode please my volume is not working galaxy tab 4 please help
Did someone solve this issue? I am also stuck with a non functioning tab due to one stuck button...
Stuck button
I had a friend with this issue. I was able to use a sewing machine needle to pop the button up. Make sure you tape or protect the side from scratches. Also, you can try holding down the volume up button. It's a meaningless combo so it may boot.

Stuck on the Options Menu with Broken Power Button

My OP3T power button has stopped working. I am going to replace the phone with OnePlus Nord. As the release is nearly 1 week away I have been trying to live with this phone for some time. I keep the phone powered up all the time. But yesterday night I suddenly lost 50% of the battery over night down to 0. So the phone switched off.
Trying to power up the phone I looked up some options online. One of the ways was to plug it in to the charger and use the volume key. As my bootloader is unlocked the volume key took me to the options menu. There I can see all the options - Power Off, Restart, Recovery etc. I can't select any option because the power button is broken. And I can't go back to the main power menu as well.
how do I come out of that menu?

I left the phone as it is and once the power discharged I could experiment again. And I have tried these things. Writing them down in case people need help:
1. using this method:
https://www.techjunkie.com/how-to-turn-on-and-off-oneplus-3-with-broken-power-button/
But then using the volume down button doesn't do anything for me. The phone boots up and waits on the first screen - which says bootloader is unlocked. And then it goes to the second screen - which says drm-verity error message. And then it goes to the Oneplus Logo and gets stuck. Trying to use the volume down to cancel doesn't work. When I connect the phone to my pc, it gives me error - "usb has malfunctioned". I tried using a friend's Ubuntu just in case of issues with Windows 10. Ubuntu doesn't recognize the phone at all. So that is a no-go.
2. Same method as above instead using the volume up button. The phone doesn't boot up at all and neither it is recognized by the computer.
3. Call up Oneplus support center for button replacement. If you are in Bangalore, India you are out of luck. OP has stopped supplying OP3T parts for over a year now.
I thought there might be a way to get into fastboot mode using just volume keys and then I could do "fastboot reboot". It looks like I am wrong.

I left the phone as it is and once the power discharged I could experiment again. And I have tried these things. Writing them down in case people need help:
1. using this method:
https://www.techjunkie.com/how-to-turn-on-and-off-oneplus-3-with-broken-power-button/
But then using the volume down button doesn't do anything for me. The phone boots up and waits on the first screen - which says bootloader is unlocked. And then it goes to the second screen - which says drm-verity error message. And then it goes to the Oneplus Logo and gets stuck. Trying to use the volume down to cancel doesn't work.

Nice find!
Thanks for sharing this info.
So I decided to test the method and found:
- it works just as well with plugging into a computer as into a charger.
- you can take your finger of the volume-down button as soon as you feel the phone buzz and the phone boots into recovery
- if you keep the button pressed until you see the dm-verity screen (on unlocked bootloader) nothing happens until you take your finger off and then it'll reboot into recovery
- it does not work using volume-up, in other words it won't boot into fastboot. In fact trying to do this seems to prevent the volume-down method from working. Having tested volume-up I couldn't get volume-down to work until I had actually booted up (using power button) and then powered off.

Thank you for testing that. I am confused though. On booting up I get two screens followed by the Oneplus logo. The first screen says "phone has been unlocked" and second is the drm-verity screen. Do you see only the drm-verity screen?
When I use the volume down button I get stuck on the Oneplus logo. The phone doesn't boot into recovery. Does that happen when you experimented with the volume up button? I mean if you use volume up first and then tried volume down does it get stuck on the logo?

This is the first screen I get (picture) after volume down, then I end up in TWRP (I'm not using stock recovery). Also, I'm running a custom rom.
I never get any response if I use volume up.

I got the power button fixed from unofficial shop. And the first thing I did was to test the volume button to recovery process. I'm on TWRP but the official OOS Rom. And it still doesn't work. I am stuck on the Oneplus Logo. Next I tried rebooting directly to TWRP using the Reboot app:
https://play.google.com/store/apps/details?id=com.stephansmolek.reboot&hl=en_IN
And while it takes me to TWRP I am stuck on the TWRP logo screen. On searching I found this thread:
https://forum.xda-developers.com/oneplus-3t/help/twrp-stuck-splash-screen-t3541037
So, the process works only if the phone can get past the TWRP splash screen.
If not, the phone will get stuck on the OnePlus logo and the only choice is to get it repaired. And repairing will happen at unofficial shops because Oneplus has stopped shipping OP3T parts.

Glad you managed to get the button repaired.
Fyi, I've never had issues with TWRP and f2fs formatted data partition. In fact, that's what I have currently.

I tried re-installing TWRP and found this:
https://twrp.me/oneplus/oneplusthree.html
This means that swiping to allow system modifications will prevent you from being able to boot if you are using the stock kernel. In order to bypass dm-verity's boot prevention, you will have to install a kernel that has dm-verity disabled in the fstab.

Maybe, the stock kernel is the issue? I am on [email protected] A custom rom might have another kernel? And the process works on stock recovery on stock kernel?

You could use the patched kernel from here https://forum.xda-developers.com/oneplus-3t/how-to/dm-verity-disable-oxygen-os-t3922324/post79357241
Alternatively, if you install Magisk it will automatically patch the kernel.

Just for accuracy: magisk doesn't patch the kernel (would be a bit tough to supply binary positions for each and every single kernel - yes, they differ from build to build - but some files in the boot partition. Droping the tripped verity bit is done by magisk after booting the kernel (that's why magisk will fail on that as soon as the safetynet api starts to use hardware backed checks for bl status - hopefully we can work around that with patched kernel sources).
