Hard bricked? Bootloop can't get past bootloader unlocked warning

Flashed back to stock and wiped everything few days ago. Today all of a sudden I can't get past the bootloader unlocked warning and the OnePlus logo flashes for a split second then it keeps doing this repeatedly. I also can't switch off the phone because the power button doesn't seem to do anything and I also can't boot into recovery. Fastboot works but that doesn't last long either, it exits fastboot mode on it's own and goes back to the bootloop again, also during fastboot all the buttons are unresponsive. The phone is not detected when connected to a PC during this bootloop, but if I do try to boot into fastboot mode and then plug it in the phone shows up as QHUSB_BULK for a split second and disappears.
As of now it's been doing this for over two hours. What are my options? Thanks for any help in advance.

As I am someone with the highest levels of skill, I believe I will be able to assist you with the powers of Google.
This exact same scenario happened to me a couple weeks ago, but for different reasons. (I flashed magisk on a non magisk compatible ROM) This guide over on the OnePlus 3 forums helped out a lot. Just keep in mind the mini version probably won't fix it for you, only the full one fixed it for me. Probably should do the same. Reason I say is because when I did the mini, it did boot up ish, but the logo was all faded and wouldn't let me get to recovery or fastboot. Also it showed up as 900E in device managed instead of QS 9008. This made it so I couldn't use the tool to flash it anymore, for some reason. I forgot what I did to fix it from there, but don't do what I did .

Yeah I saw this exact thread on the OnePlus forums, thing is I can't get it to power off at all. The power button is completely unresponsive even after holding it down for more than 40 seconds. I'm just going to give it another shot once it dies on its own, hopefully one of those methods will work. Thanks anyway though.

Sorry for replying old post. I have been facing this critical scenario for last two days. The phone never turned off, always looped through unlock warning. No, button working. Can you please share , what about your findings at the end ??

[SOLVED] I think I bricked my brand new pixel xl 2. Will appreciate any advice.

Hello friends.
I got my Pixel XL 2 yesterday and today I'm in trouble already.
I unocked the bootloader, installer twrp and rooted with magik succesfully, but I had trouble installing my apps (titanium backup gave me a parcing error and the googgle play store wanted me to pay again for my purchases for some reason), so I figured I do a factory reset so I get prompted to restore from my old phone via cable. So I went to settings -> factory reset.
The problem is that when android rebooted to erase the data, I instead got dumped into twrp on a screen that says Mount Decrypt Data and is asking me for a lock pattern. But the screen doesn't responds, so I can't proceed. The power hard button just toggles the screen on and off but it does not reboot or turns the phone off when I hold it, so I don't know how to get to my bootloaded to maybe reinstall a factory image or what else to do.
I'm just stuck on that screen without options.
I would very much appreciate any advice.

Hold power, vol up and down buttons until your device turns off.. then go into bootloader by holdind vol down and power

I thank you very much for your reply.
I did booted succesfully into bootloader, but now I'm affraid I jumped from the frying pan into the flame because now my phone doesn't power up at all. If I connect it to the charger I don't get the battery with a lighting bolt that I'm supposed to get. The only life sign I get is if I plug it via USB to my computer, I do get the sound that windows plays when yoy connect something, but other than that, the phone seems to be dead.
I'm guessing it's something with the hardware?

hold the power button till it shuts off

Was the battery low when you started this?
Are you familiar with ADB? When plugged into the computer type adb devices or fastboot devices does it return your device serial number? If so type adb reboot bootoader.
If not I would hold the power button for a good 20-30 second and see if you can force it to turn on or reboot and immediately hold volume down to get back to bootloader.

Did you get anywhere with this? Just curious. I know you're probably upset, we're here to help if we can. :good:

Thank you very much to everyone for your time and help.
Thanks to your advices I was able to solve it. In case anyone ever finds himself or herself out in a similar situation, here's what ended up happening:
After holding the power button for about 30 secs as Namolas sugested the phone did reboot itself and brought me back to that twrp mount decrypt data screen asking me for a lock pattern. It was then just a matter of adb booting to the bootloader and install a factory image as usual.
Thanks again. I appreciate it guys.

NOOB: hard bricked op3, volume up button hasn't been working

First off, I did do a search, but as far as I can tell no one has had this problem so far.
This is all after modding using a tool kit: (i can't include the url but it is the toolkit by neisor on the oneplus forums)
tldr: phone stuck in bootloop, computer wont recognize the phone, maybe because it keeps shutting off and then booting to the 1+ logo, then shutting off again, would drivers help? what can I do about the volume up button?
So for a while my volume up button hasn't been working, and the mega unbrick post shows that I need to hold the volume up button for at least 25 seconds and while holding, plug my phone in. I have also seen some posts that say the volume up button could be a software issue, and the button itself could be working, and it is just not registering, as well as someone saying that you could take the back off and manually press the button, instead of using the bar on the outside of the phone (would this work?). I have gotten the button to work in the past by pressing the volume up button to the side instead of straight in, but I haven't been able to get it to work since my phone got bricked.
Another issue: my phone is stuck in a boot loop, I can't access fastboot, and I'm unsure of recovery because my volume up button is not working. would it be worth it to deal with the constant vibrating to try to get it to recovery?
I have been able to shut the phone off by holding the power button for something like a minute and a half, though.
This is my first post, and if I have broken any rules I am very sorry, but I need help and am tired of not having a phone.
Thank you everyone,
Mark
Edit: this is what I did to root the phone:
1. download the toolkit
2. unlock bootloader (when fastbooting the phone said unlocked at the bottom, and a message about not being secure showed every time I rebooted the phone)
3. flashed twrp (no issues, still booted, recovery went to twrp. for some reason I had to flash multiple times as every now and then recovery would revert to stock op, although I did make a backup through twrp)
4. send supersu zip file to phone, install using twrp (phone would not boot, op logo stayed on phone for 2 hrs + until I rebooted to fastboot and tried to reinstall the backup I made, still nothing)
5. Try magisk (still stuck on op logo)
6. try to go back to stock, accidentally lock bootloader (now the phone is stuck in bootloop, don't know what to do from here as I cant get to fastboot and am unsure of recovery's accessibility.)

If you are sure you have a broken volume button, you need to replace it first in order to get the phone fix.
Correction:
Fastboot/bootloader = Power+Vol Up
Recovery = Power+Vol Down

This happened to me except I didn't even get anything appear on the screen -- the phone just periodically vibrated with the screen not even light up. I tried the reset toolkit which is meant to flash your phone back to normal using Qualcomm drivers or something, but that didn't work either. Eventually I had to send it to OnePlus who fixed it for free in under a week! They said the motherboard had failed.
I hope you get this fixed!

Thanks

thanks for the correction, I will keep trying the volume buttons, if it doesn't work by the end of today I will search for a new volume button.

Damn, that sucks, and besides being unfixable (doubt it), this is my biggest fear. I'm in the US and really don't want to have to ship my phone to china to have it fixed. If you are in the US as well do you know if there is a OnePlus branch I can send it to in the US?
Thank you,

There seems to be one in Texas. Anyway, contact OnePlus and they may try to solve it over the air.
Apart from that, did you install the Qualcom drivers properly? Even with your faulty power button, try to hold it down for 40+ seconds (for the phone to switch off) and then immediately hold down the volume up button for 10 seconds and then plug in the phone to the PC. I know I am merely repeating the instructions of Naman Bhalla in his Mega Unbrick Guide but it is crucial to do them correctly especially the installation of the drivers. Try these steps repeatedly because for some people, the phone gets recognised after repeated attempts. Or else replace the power button and then try these steps.
I had to use the Guide last month and successfully resurrected my dead phone.

Can you boot into recovery by pressing power+volume down buttons?

Update: Got phone to show on computer as qualcomm under coms and ports
So last night I went ahead and held volume up for about 20 seconds, then plugged the phone in, keeping the volume up button pressed the entire time. my phone stopped bootlooping and showed up as a qualcom device! So I have downloaded the new driver the stock os, and am going to proceed to try to unbrick my phone.
Wish me luck,
Mark

Yes, I did, and its working so far

I still need to turn off the signed drivers features ( a huge bi*ch, I have to use another computer to contact microsoft or something to get my computer to load when I turn off safe boot or whatever its called), but once I do that I can install the driver and attempt to reinstall the stock os. Hopefully everything will go well.
Thank you,

So far recovery has not been loading, just the bootloop, but I have gotten the phone to power off by pressing the power button for 40 seconds, and the volume up button plus plugging in does make the phone register as qualcom 9008 or something like that. Basically everything is going well so far, and the faulty vol button seems to have been a software bug, as it does work when plugging it in. I will try to get to fast boot, but it did not work last time.
Thank you,
Mark

Help! Pixel 3 XL wont turn on after Android Q Beta 6 OTA Update

Hello guys.
I just bought my Pixel 3 XL phone straight from the Google Store and it just arrived two days ago. After learning about Android Q, I opted-in on the android beta and downloaded the Beta 6 OTA update to my phone. The phone downloaded the OTA and installed it and it seems all is well until the moment it rebooted. It didn't turn on again. It won't turn on. I tried to force restart it by pressing the power button 10 seconds, 30 seconds, or even 1 minute+, won't turn on, no haptic feedback, nothing. I even tried the power button + volume down combo. I also tried plugging it to the original charger it came with for 30 minutes, nothing.
Before this, I have experience with flashing stock and custom roms with pixel devices and other brands (I have owned the OG Pixel until it wont boot due to its motherboard issue), and while normally, I could have just unlocked the bootloader and installed the beta firmware thru fastboot/recovery, or even installed a custom recovery, I didn't and instead tried the OTA update thingy (which claimed that you don't have to unlock your phone or anything). I didn't expect that it will brick this early and unexpectedly.
My suspicion would be that the OTA update broke the bootloader itself, or the firmware that loads the bootloader, thus not responding to the power button correctly. It's also not a power problem, because the phone warms up when plugged to the charger. Also, I download and applied the OTA while the phone is charging (around 70%). Could that also be the culprit?
I'm at my wit's end here. I'm thinking I should RMA this phone, which I haven't done before. Are there any similar issues like this before? Did anyone else had similar issues like this one?

Plug the charger in and hold all 3 buttons together, not saying it will work but worth a try, it deletes battery stats and cache, if it does boot then keep hold of them for about 40 secs, hold them for over ten seconds even try for a whole minute, this sounds like hardware fault to me though. Also, if youve just bought it, swap it.

I have tried what you suggested. Still nothing.
If I can I'd try to resolve this without returning the thing but yeah, it may really be a hardware fault. Guess I have to wait for a miracle to happen (like the phone turning on by itself after several hours, like with some posts that I have found around).
If all else fail, maybe I'd just ask Google to replace it.
Thanks anyway :good:

You may want to try to see if you get a USB notification from your computer on Windows and if it does try to flash it Back to stock. Hope it works

Have you tried making an edl cable, to see if the phone boots to qualcomm flash/diagnostic mode. I dont understand why no one in this thread as mentioned EDL mode, its a life saver for when you brick your device. This allows a full factory image flash through qualcomm flash mode. Plenty of tuturials on internet for EDL. (Emergency Download)

My nervs.. I can't unlock my bootloader

Hello xda members!
I am really stuck and I have lost many nervs trying to unlock the bootloader.
Well, I am not new to this and never had a problem the last years with several phones but this one s***s balls, sorry.
In the settings I checked for "OEM-Unlock" of course. Rebooted to Download Mode but I don't get the screen where I have to press Vol-Up to confirm unlocking the bootloader. What's up with that?
I tried everything I could think about but as I said I'm stuck and you guys here are my last chance.
I really hope someone can help me.

Let we make it clear, If you enter download mode from Android Recovery, you will not see the option to long press volume up to unlock the boot loader. You will see it if you enter download mode: Turn off it, press and hold volume up + volume down together while pressing these keys, connect the phone to PC using USB cable.

enter download mode and long press vol up should fix the problem

I have the same problem with my galaxy fold F900F ..
I can enter to green screen ( download mode ) But there is no option for long press volume up ..
only I get long press volume down + power to restart the phone ...
so how to confirm unlocking bootloader in this case .. ?

Hello,
The problem usually comes when you unlock and lock bootloader too many times (2 or 3). To fix this problem you need to go into download mode - flash the stock firmware from samfw.com and then setup you phone. Then, unlock oem will be available in developer options and then you can unlock bootloader from download mode.
Hope this helps.

Hello,
I think you need to flash the stock firmware.Then, bootloader unlock will be available in the download mode.

FYI If anyone is having this issue like me, just use power button + vol up + vol down button while powered off then connect usb cable, and it worked (for me!)

hey all. I had the same problem and managed to make the hold volume up to unlock option appear by connecting to internet, making a google account and samsung account, and fully completing the setup (no more "finish setting up your phone" notification)
Hope it works for you! there might be some waiting period as I did this over several weeks of playing around with it.

if you want to remove that finish setting up notification, just go to notification info then app info and disable that app, it's redundant anyways

I had the exact same problem with my SM-A505W! I looked everywhere and could not find anything. Eventually, I found a couple of things relating to a bug where you either had to plug in the USB-C earbuds that came with the phone or plug it into one of your computer's USB 2.0 ports. I did the latter.
This is what I did. First off ensured my phone was just like the one noted above by noobynoob7. Next I plugged my phone into a USB 2.0 port on my laptop. At this point I heard my phone connect and noted that the screen showed me my phone was charging.
***Important*** I pressed the volume up and volume down at the same time; then I pressed the power button, holding all three down simultaneously! At this point my phone immediately went into the familiar download mode with the option to long press the volume up button to unlock the bootloader.

I am about to return a S10e G970F because I can't get past this as well. Button combinations mentioned don't do anything for me, completely lost.
EDIT: Fixed now somehow. Sad that I am now apparently forever stuck on Android 12, even with custom ROMs?
