Hi, I have a oneplus one running cyanogenmod (one of the first lollipop nightlies, not sure which). The phone is rooted, and has been working fine since march. I was simply in the car using it and upon leaving, next thing I know it's stuck in a boot loop.
I get:
Vibrate
1 sec black (but on) screen
oneplus "powered by android" boot up screen for ~6 seconds
1 sec black (off) screen
Just repeating.
Holding down the power button does nothing. Holding down volume down & power will turn the screen black, until the point at which I let go of the buttons, when it goes back into the loop.
Holding down volume up & power gives you the "fastboot mode" message, but then goes back into the loop after a few seconds of showing that.
So far I have left it charging for 6+ hours, had it discharge fully (which was the only thing that stopped it from constantly restarting) . I have plugged it into my computer, and it is recognised and the drivers start installing (haven't plugged it in since formatting computer), but it turns off before they can be installed.
I was advised to come here from reddit, hope you can help
Have you tried this?

I didn't want to try it because from their description, my phone isn't hardbricked. The oneplus "powered by android" screen comes on, and it will say fastboot mode if you boot it into fastboot mode, it just restarts after a few seconds of saying that.

Exactly how long do you have access to fastboot for?

About 5 seconds
Hmm, probably not long enough. Will it give a response if you issue this command?
Code:
fastboot oem device-info
Hello, I recently came on a pixel phone to build and use lineageOS on. Upon rebuilding, I believe I performed adb sync wrong the device and damaged system. After that, my adb keys became unauthorized and I am unable to access the bootloader menu(I press power and volume, but phone boots into Bootloop). I tried the steps to get to bootloader menu, but the phone doesn't power completely off, and when I press the power button it gives me the launch screen saying press power to pause/continue boot, not allowing me to go into bootloader
My bootloop goes like this: Bootloader integrity screen(bootloader unlocked, cannot be verified) --> Google loading screen --> Android recovery. This shows 2 options with the message, "Can't load Android system. Your data may be corrupt. If you continue to get this message, you may need to perform a factory data reset and erase all user data stored on this device". The two options are to try again or data reset.
I press try again, and the same bootloop ensues, sometimes getting to lineage loading logo, but then back to the same recovery error regardless. If I press the buttons(power and vol up), to go into recovery, it just shows an android with a warning sign above it, giving a message saying "Error!" on the bottom. My adb on the computer shows as unauthorized, so I don't know how I can fix this. Google has said the warranty is expired and cannot do anything to help. Ideas to fix? Thanks for help in advance!
Use power and volume down (not up) to go into Fastboot mode. Then flash the stock images

I tried that, but whenever I press any button, the phone is never turning completely off unless it dies. Even after that, it goes to the screen showing the secure boot integrity(Press power to continue/stop boot)
How can I completely shut off the device and restart it? And if system is messed up, will that leave my bootloader intact(I'm assuming so as boot is a different partition?)

Does holding down the power button for 5-10 seconds turn it off? Or if you do that does it appear to turn off and then restart?
If that fails to turn it off, try just holding power and volume down for 5 seconds, and if the screen flashes (goes off and then on) let go of the power button but keep holding volume down and hopefully it goes into Fastboot.
That should work unless you have a dodgy power or volume button. The bootloader is completely separate to the boot partition, and the fact that it's doing anything at all suggests that it's still functioning.
Only other option I can think of is trying ADB commands when it's in recovery mode, e.g. adb reboot bootloader. However, if you have the stock recovery, that may not work.

Thank You!!! It didn't work in the bootloop, so I had to let the phone drain its battery and shut itself off, then I was able to enter the bootloader and reinstall lineage. Thanks so much!

Is ur bootloader unlocked? If so, use twrp to perform a full wipe and install from twrp as well. Of you can't access trwp, and are in a bootloop, do the same thing I did: let the phone lose all it's battery, so it's outta the loop, connect the phone to a charger, then hold power and volume down. This should get you into bootloader mode where you can then use fastboot to flash twrp.

My bootloader is unlocked but phone not detected on pc only black screen nothing else.... Red light flashes whenever connect to charger
I have searched and looked for alternatives on how to maybe enter download mode but have not found any solution. I have tried phone off then vol. down + bixby then plug in usb, also pow button + bixby + vol. down then plug usb but every time I do this all I get is a circle with a lightning logo with battery percentage. I also went into recovery mode and tried rebooting into bootloader however that just ends up rebooting back to the recovery menu. Please help. Thank you.
anyone with any tip on what might help or be the issue? I have an exynos version.

Hi, try to reboot into bootloader using ADB.
First off thank you for the response.
I tried that as well however maybe I did it wrong. Is it? adb reboot bootloader or adb reboot download
It's so strange you know cause I've tried so many different ways and I thought that rebooting to bootloader from recovery menu would definitely work however all it does is reboot back to my home screen.
Power off phone and just hold down pwr+vol up+ Bigsby for like 8ish seconds and it should boot to download.
Also adb/fastboot is a second route, read through this the below link. Make sure you have the Samsung drivers installed and adb/fastboot properly installed and prerequisites. https://www.theandroidsoul.com/unlock-bootloader-via-fastboot-android/
Or try to boot in safe mode
Hold power button when phone is on, then long press power off, and then select safe mode. https://www.verizonwireless.com/support/knowledge-base-223011/

well apparently I can't boot into safe mode either, while screen on I long pressed power button then long pressed power of for more then 10 secs but that doesn't do anything
crazy thing is I'm able to boot into recovery with no problem but that's about it. also adb does recognize my device as I can see the characters after inputting "adb devices"
Hi there,
I was trying to flash TWRP on my S7, but I cannot get into download mode. Here's what happened so far.
installed Samsung drivers and Odin
unlocked OEM
got phone into download mode by pressing Vol Down and Home buttons during reboot
connected phone, but Odin wouldn't recognize it
left download mode by pressing and holding Vol Down and Power
phone was recognized after rebooting PC
tried to get back into download mode with Vol Down and Home
Phone boots into safe mode, exits safe mode without problems, but no Download mode to be entered
tried wipe cache and factory reset, problem persists
tried Vol Up and Home just for ****s and giggles, same deal
any ideas? :crying:
thank yooouuuu!

So for clarity download mode is, when the phone is off press, vol down+home+power, in that sequence.
To exit safe mode, long press the power button and choose restart from the popup. If this does not work power off the phone and wait a minute before powering on.
To prevent problems with Odin, debugging should be enabled in developer options menu.

Well, I used vol down and home after restarting, which worked the first time...but now your version works, so thank you!!!:highfive:
Ok Guys So I Shouldn't Have Done This But I Used Fastboot To Flash Recovery And I think I Did It Wrong. It Said "ok" And Finished And I Rebooted Phone It Resetted And Then Stuck On The Orange State Bootloader Message. I Do The Recovery Mode And Goes Black And Nothing Is Responsive For a While, Sometimes Longer Than Others. This Happens If I Start Phone Normal Or Try Fastboot Or Download.
Because Of My Mistake I Cannot Connect To Pc Software And Im Not Sure Of What I Can Do. I Feel Like Im Not Going To Like The Answer For This But I Got To Take The Blame For This.
Btw i Have A Samsung galaxy Note 20 Ultra Sm-N986u
I think your phone is hard bricked
so you can't get fastboot using volume up+power or via adb?
rescue from manufacturer site pos or just device not being recognised?
It isn't hard bricked it's just way of Samsung trying to make life of simple people more difficult, people who paid for Samsung phones lots of money.
To sort that screen issues what you can surely do is,
Simply press volup + voldown buttons at the same time, no matter if you're on that orange screen or whatever just press those those two buttons at the same time and keep pressing them while you connect your phone to pc. you will boot into download mode. Then flash stock firmware for your phone. After stock of flashed Reboot and start your phone, go to developer options see if oem unlock option is there if it is then oem unlock it if it is not then go back to settings manually change date to year ago, then go to updates disable auto update, connect to WiFi, and press on update several times untill window shows up saying no updates, then go to developer options you should see oem unlock, unlock it.
Then boot into download mode and make sure you have working copy of recovery.
And make sure you follow instructions of whoever recovery you installed on how to boot into recovery. I have S20 plus and too had troubles with it, and the only working recovery for my phone is twrp customised. To boot into it after flashing recovery from odin auto reboot disabled I pressed voldown and power, USB cable connected, then after screen goes off I changed from voldown to volup while kept pressing power button and cable connected. Orange screen with warning showed up for 5 sec I kept pressing and it bottled to twrp and then I was able to install custom rom beyond rom and while installing in aroma I was able ti choose option to remove orange screen.
That's it.
I ran into the same error. I mistakenly loaded twrp's recovery into userdata instead of ap section. The phone was stuck at the orange screen and nothing was happening whatever i pressed. I waited till the battery to dry out and with 0% battery, i directly connected to pc and was able to get into download mode. Then i flashed stock and everything is now back to normal.
