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.

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.

that happened to my old ativ s as well, it was due to a broken power button (electrically stuck, not mechanically) the only solution for me was to solder a new power button on it. But I just used it as an excuse to get a new phone.

I haven't, it may be very hard depending on the phone model, I just removed it with pliers so I could boot it with a usb cable and I got all the data I needed from my phone.
Can you get your phone into recovery or fastboot mode?

if you install gravitybox and xposed there should be an option to turn on the screen with the volume buttons (I'm not sure though, it might have been another module) so you could use that as a temporary solution.

with phone turned off, (you can remove the battery and re plug it), hold the volume down button and connect it to the wall charger(do not use PC,it will trigger lg download mode), then you will be able to go to fastboot.
Once there you can:
fastboot reboot to boot to normal OS
fastboot boot twrp so you can install a rom or any other mod

fastboot reboot - to boot into normal OS

Now I'm just waiting my new power button
i had this **** sorry for swearing i thought its something with my ROM CM13 Nightly I tried the repair service they said that they changed the power button no data was deleted so its probably the button but some one had a guide how to get the phone out that **** using your PC and manual ADB commands ( No program command line only )
I need help with this issue
when this problem reached me it was a meter of replacing the power button itself (it's like stuck there) by the way my phone was still under warranty so they changed it for me

Hi all,
My Nexus 5was running stock Android M till last week and I wanted Android N. So I rooted my phone installed TWRp and loaded android N by @santhosh. Everything went well but at times some apps kept crashing including TWRP. So I decided to to do a clean wipe. I did a clean wipe from recovery but after that my phone is not booting up. It's stuck on bootloop.
I am not able to boot into recovery mode also is there any way to save my phone?
Pardon my English.
Are you able to access the bootloader (hold power button + vol down until the phone boots)
I suggest using NRT to flash a stock ROM.

No i can't. It will go to bootloader When I press volume down + power but only for a second or so.. After that it'll bootloop.

Sounds like a dead power button?
Not sure, never had this problem.
But that is a common issue
The fact that the phone is not detected by the phone makes it difficult to re-flash a stock ROM.
If it is a power button issue, I recommend removing the motherboard, cleaning around the power button with pure isopropyl alcohol., quickly press and release the power button using a bit more pressure that usual, replace the motherboard, and try again.
Hello.
What kind of combination of keys enter the "download mode" mode?
Vol down plus power does not work on the off U12 +, and under the system it even diminishes in dignity despite pressing "power".
Vol UP and power also does not work.
Boot to Bootloader and than select Download Mode with volume buttons (working for me).
From system you can try:
adb reboot download
Click to expand...
Click to collapse
(not checked)
Since u12+ has no physical button,and the edge sense doesn't support combine key,the method to enter the bootloader is special.
STEP.1 Press POWER button for 10s to hard reboot,you should feel a long vibration.
STEP.2 When you feel the vibration,press the VOL DOWN button immediately.Keep pressing it until you enter the bootloader.
STEP.3 Use VOL UP&DOWN to switch,POWER to enter

An other method for me is POWER OFF and then restart with POWER BUTTON pressed until vibration and then press VOL UP.

Good question. I am missing a twrp developing thread as there are already guys testing, but they only posted in the ordering threads:crying:
It works a little bit different on all treble A/B enabled devices. Those got two boot images, boot_a and boot_b, and don't have a recovery partition any more, as it got incorporated into the boot partitions, and is thus sharing it's space with the kernel. All previous device as well as treble A-only ones still had a separate recovery partition. But that very fact changed with such devices as the U12+ which got full treble support with seamless updates.

The haptic keys don't work in combination, only one-at-a-time, so there must be some other way.

Lol, I take it this is your first Android phone? That's the normal stock Recovery. As it was said before, combination of buttons do not work. In Bootloader and Download Mode the volume buttons are switching selections and power selects the highlighted option.

On the older HTC's you could hold volume up and down then press power to enter the stock recovery options. I remember doing this with the M8 I think, it's been quite a while. Lets see if I remember how to embedd images, lol

Yes I understand that part for combo buttons to enter recovery, bootloader and download. Now it is power down and restart holding down volume down button. However there is nothing to do while in stock recovery.

I didn't explain fully, my bad. When you accessed the stock recovery with the red triangle with the exclamation mark, that's when you held power down, up and press power to access the screen shot I attached before. Those were the stock recovery options.
It's irrelevant at this point since I don't think they include those options anymore for the newer stock recoveries. I could be wrong though.
I haven't tried to boot into the stock recovery in years so I haven't checked if it was included in the latest phones. I'm supposed to get my 12 today, I'll try to play around and see if it's included in this one, but I'm not holding my breath.
Edit: I love your themes BTW.

This works on all HTC devices prior to 12+. The question is only about the subj phone.
Easiest way - From powered off state, hold Vol down button and connect the usb cable to either power outlet or a PC, will boot to download/recovery/ etc .

There is no problem to boot into FastBoot mode and then choose any other option: Download/Recovery/System.
The issue is that I can't pass Recovery Red Triangle. HTC support also recommends to hold Power while pressing VolUP, but this does not work on U12+ with the haptic buttons.
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
