Soooo, flashed boot, forgot to flash vbmeta b4 rebooting. Rebooted, got device is stuck on a bootloop.
Now fixes to stop the bootloop require going into fastboot mode, but how can I stop the loop, and start the fastboot mode?
Thanks in advance!
Somewhat fixed, gonna leave here how for the future. When stuck on a bootloop, from the moment the OnePlus/Android logos appear on screen, press "Volume Up" and "Power Buttons".
IMPORTANT: when the screen turns off, release the keys, or the phone will reboot and not break the loop.
So now., can turn off the phone. Have been trying to get to Recovery mode with no success.
Have tried starting the turned off phone by pressing:
Power + Volume Up -> powers on or off the phone
Power + Volume Down -> nothing
Power + Volume Down + Volume Up -> nothing
So now, just need a way into recovery/fastboot. I must be doing something wrong, maybe pressing the buttons for too long or smth like that. Has anyone unbricked an phone like this before?
Also, something wierd is happening, the phone auto boots when I connect it through USB.

if you're on android 12 theres no way you can recover from it without going to the Service center. if you're on android 11 volume down + power should go into bootloop.
the main problem in Android 12 is that fastboot is broken. and it will boot into fastboot for a milisecond or two then reboot out of it

Hey! Thanks for the help ko_hi! Sadly It is on Android 12, so I guess I'll go to the Service center!

Update: I messed around with fastboot a bit more and managed to brick it entirely. It's stuck in a boot loop now -- it won't even power off -- and there's nothing I can do about it, so I just took it in to get it replaced.
Hey guys, I know this thread is very similar to others that have been posted, but I've already looked through them and haven't found anything that works for me yet.
My phone was already running rooted stock with TWRP for the recovery. I tried flashing CM10.2 but it was for the wrong model (I downloaded D802 but my phone is of course D801. Oops). Upon reboot, the LG splash screen appeared and then immediately went to a black screen saying
Code:
Fastboot mode started
udc_start()
When I attempt to turn the phone off it just reboots to that screen again. I am still able to use fastboot, and have tried wiping the phone and re-flashing TWRP. It doesn't throw any errors but I still can't actually boot into recovery. I can't use fastboot to flash a new ROM onto the phone though, since it doesn't like .zip archives apparently, and I can't find a .img file of a ROM anywhere.
When I try to use flashtool as described here http://forum.xda-developers.com/showthread.php?t=2541087 it says the device is not connected (probably because it's not in download mode?).
Any help would be much appreciated. All I need to do is get into recovery, it shouldn't be this hard.
That's the same error I got a few days ago when I mis-flashed a new recovery (oops. and be careful when you use 'dd', because a typo can nuke your recovery). I'd get that error message if I tried to boot into recovery, but if I just let the phone boot, it would boot fine. It was easy to fix, but that was because I just used Terminal Emulator to re-flash recovery.
Your best bet might be to go back to stock. Try this thread.
similar issue, but not quite

I'm not in a boot loop, as I can power off and it will stay off. But I am stuck at the Fastboot mode started screen (I can't get download mode to come up). When I do try to get into download mode it flashes for a second, but then goes back to the fastboot mode screen.
I'm hoping to find an image that I can use the fastboot flash recovery command with to re-write my recovery partition.
Any suggestions on where to find this image file? Or am I going down the wrong path?
Thanks,
Joseph
Did you get it to work? I am in the same mode.
I'm stuck here as well. Looking for a fix
Did you guys find a fix? I need help with this...
similar thing here with me
any solution
i cant boot at all, not into download mode, nor recovery,
got this too because i was installing a note3 rom to my d800, acciodentally of coarse. i managed to boot to twrp by doing the power and volume down technique. and from twrp i restored my recent backup
To anyone still stuck in this situation (reboot loop, no recovery etc):
- Unplug the phone from the USB cable
- Hold down the power until the phone turns off
- Wait a couple of minutes with the phone off
- Now hold power and volume down buttons
- When LG logo appears - release power and volume down and hold them again
- When you see a white screen with "reset to default instructions" -- do what it says, meaning pressing the power button a couple of times
THAT should work.

All I did was hold power and volume down until the LG logo came on (not when it flashed for just a split 2nd) and then pressed and held power down again and it came to the white screen. Then I pressed power 3 times and got into recovery

Not sure if you've tried this. To power off fully, press and hold the volume down and power buttons. Do not let go of the buttons. The phone should turn off and the LG logo should appear. Continue holding until after the LG logo disappears. The phone should be fully off and won't turn back on at this point. If you don't see the LG logo, just keep the buttons pressed for about 10-15 seconds and you should be fully powered off by then. You should be able to enter download mode from here (press and hold volume up button while plugging in USB from computer). If you are able to enter download mode, then use the LG mobile support tool in my thread and follow the instructions. This should flash the latest stock system to your phone. If that doesn't work, I have a link to an alternate method for flashing the latest stock system on your phone. Hope this helps.

I hve tried this but after i confirm the reset it staight away takes me to the black screen
After trying to flash a TBO calendar/calculator inverted app I rebooted from recovery only to now be stuck in a bootloop. The only thing the phone will do is begin to reboot itself if I press all three buttons to "hard restart". (power+vol up+vol dwn). Tried using adb/fastboot to reboot into recovery or bootloader but I don't think that the phone is far enough into the boot process to be recognized by adb/fastboot because typing adb reboot-bootloader just returns "waiting on devices". I have also tried to use power+ vol dwn combo to reboot to bootloader. I have noticed that this only works for stock and other certain ROM's. It's a hit and miss as to why this occurs.
So right now I am stuck in a perpetual bootloop with no way to get to recovery or bootloader. I don't know of any other way of getting into recovery to restore a nanroid. Any one have a good suggestion? Please!
The combination of power + volume up (for like 10 or so seconds) will force a reboot. As SOON as it reboots you just need to hold volume down to get into bootloader.

I'm having the same exact problem, I figured out the volume up + power, turns the phone back on in a hardboot. But, exactly how long do you need to hold the volume down button for once it's rebooting?? I just got a replacement phone on 9/24, my previous phone had no problem with this & had the option of fast boot in the settings. Just rebooting my phone takes FOREVER to turn on (or so it seems in comparison). Any idea how or why this is now? Is it due to an update, can I uninstall the update to go back to a fast start setting?? Thanks!!

When you hold the volume down button are you also holding the power button? You need to use volume up + power to restart. Then, when it restarts, immediately hold volume down without letting up on the power button. Needs to be volume down + power to boot into hboot. As for now long do you hold it, until it boots to hboot.
Thanks for the info...
Thanks for more details I'm pretty sure I did let up on the power button thinking it was keeping it from loading. I'll try this out now!!!

Try to hold all buttons of your phone down for about 10 seconds and then your phone should restart itself.
Force your device to reboot by holding volume down, home button and power button at the same time. Hold the buttons down until the device reboots.
From then you can attempt to flash stock firmware via Odin and then making sure that you have enabled OEM unlock in developer options and that you have the correct TWRP for your device (Check MD5, to make sure it isn't corrupted)

Hey! How did you manage to solve the problem? I'm having the same issue.
Greetings of the day,
Hello everyone, I'm having a oneplus one 64GB phone that is not getting start, everytime i connect it with the charger it goes into a bootloop. Yes the phone was rooted and I was using a custom ROM with the default kernel. The issue started when I tried to reset the phone to battery settings. I think I somehow messed the kernel and now it is stuck in bootloop. The problem is that I can't connect it to my computer or put it in debug mode as it just restarts again. Any idea how to actually boot it so I can install the kernel and ROM again?

No, My phone is not getting on but whenever i am connecting it with my charger the phones goes in the Bootloop, and when i am connecting it to My PC while pressing Volume Up + Power Button Pc shows that the Unrecognized devices has been connected.
And i think phone is Hard Bricked. I have tried ADB software and one plus 1 drivers manually but it didn't worked too. I have tried minimal ADB too but it also didn't work.
Kindly let me know about it.

Volume UP + Power should boot in fastboot mode. Volume Down + Power should boot into recovery. First, try to boot recovery.

I have tried both, but nothing happens with it, Volume UP + Power shows the unrecognizable device is connected and Volume Down + Power does nothing it continues with bootloop .
Have you got Developer Options enabled?
Goto About Phone & Tap Build Number until Developer Options is activated. Goto Developer Options> Advanced Restart & enable the switch.
Press power button->Restart->Recovery.
It will now boot into Recovery.
Also have you tried keeping hold of power button whilst it bootloops. Keep holding the power button until it powers off. Then press Volume Down & Power Button to power back up (you might see a slight flicker onscreen that means it should go into Recovery mode). Keep hold of these buttons until you gain Access to Recovery Mode.
This will allow you to Recover or flash a different ROM.
If you're having issues connecting to a computer (Windows) try downloading Windows Media Center for your version of Windows. This will install media drivers to recognize your phone.. If all went well you will get the pop up with A0001 (Codename of OnePlus One). From there you should be able to enter fastboot mode through ADB.
If this doesn't help you, I'm sure that someone else will untangle the puzzle to get your device in good working order buddy. Good Luck.

Hello,
My phone went into bootloop and I cannot do anything to open it. I cannot connect it to the computer or wipe all data from the phone. I have never done aything on it and the bootloop happened while i was sleeping. Woke up to find that the phone is constantly rebooting. Also the phone does not stay in fast boot mode. I managed to open the recovery mode and select wipe all data but the process interrupts and the phone reboots again. I also think that the power button might have a problem because when i only press the volume down button the device enters fast boot mode. Thanks in any help
Your power button may have been stuck. Try to press it harder or from one end.

I have opened to phone to see that the power button was indeed stuck. Had to jam a piece of paper there to make it stop for now.
Install the Recovery ROM with MiPCSuite.
