[Q] T-Mobile LG G2 stuck in fastboot, can't get into recovery

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

What if I'm stuck on a black screen no matter what buttons I press.

Unable to do that.

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.

Unusual bootloop - can't access recovery OR fastboot but loops on "optimzing apps"

Unusual bootloop - can't access recovery OR fastboot but loops on "optimzing apps"
I had my US version OpO 64GB working with CM12 for quite a while, rooted and bootloader unlocked with TWRP (possibly 2.8.6) installed, then some months ago I tried upgrading to CM12.1 through CM updater. This failed miserably - The phone started bootlooping on "Optimizing apps n of N" - as soon as it finished optimizing apps, the phone would reboot and start optimizing again. Booting to safe-mode (Power + VolUpDown) also fails in the same way (though optimizing fewer apps).
I tried rebooting to recovery mode holding Power + VolDown but it just gives a quick buzz (vibration motor) at the "1+" screen and reboots. The same thing happens when I try to boot to fastboot mode with Power + VolUp. So I'm completely stuck. All the guides show being able to boot either to fastboot or recovery (soft-brick) or else the screen being completely black/unresponsive (hard-brick). My phone is neither of these!
I got frustrated enough that I've let it sit on the shelf for the past 6 months, but now I'd like to fix this. All help appreciated.

That's impossible for me to do since I can't get to launcher or recovery.

No acess to recovery?? Then better take it to service center... Atleast can u boot to fastboot mode or adb accesible then use oneplus one toolkits
---------- Post added at 11:34 AM ---------- Previous post was at 11:31 AM ----------
Install oneplus tool kit, while optimising apps it gets dectected by pc, just make it reboot mode & do reset.... Dnt worry this can be fixed, if all these seems messy then take it to service center

while things are loading, have u tried to hold vol up + power for 10 seconds or until the screen turns off and then hold vol down + power button until the oneplus logo?

Yes, just tried it. Same thing as described in my original post. When I hold power+volup the screen goes blank. I switch to power+voldown until the 1+ logo. At that point:
1. If I continue to hold the power+voldown key through the 1+ logo, the screen goes blank briefly, the phone vibrates once and reboots. If I continue to hold the power+voldown key, the vibrate&reboot cycle continues indefinitely
2. If I let go of either the power button, the voldown button, or both at or before the 1+ logo, the phone boots normally and goes to "Android is starting... Optimizing app n of 119). When the optimization finishes, the phone instantly reboots.
It's like the phone recovery is gone or inaccessible. Could this have to do with the phone tampering setting? As I said, I had this phone rooted and bootloader unlocked, working fine with CM12 for some time before trying an in-place upgrade to 12.1. That's when things went south.

Phone won't boot after factory reset / Open Beta 2

I have no idea why, but the phone won't boot after I initiated a factory reset while on OB2. Only thing the phone responds to is when I press Power + Vol DOWN for 10 seconds. It vibrates, the Android logo comes on and then the screen seemingly turns off again.
Tried getting into recovery but phone does not seem to respond to Power + Vol UP. It did once, but did not go into recovery or fastboot after letting go when the Android logo came on.
Any suggestions?

MSM saved my bacon. Thank you XDA!

(help) Bootloop after OTA update

Hello
My stock A515F/DS received an OTA about 3 days ago. After it restarted to finish the update, it got stuck in the boot logo. It will reboot on itself from time to time, and I was able to reboot it manually by pressing vol down + power, but I can't get into recovery or donwload mode (by pressing vol up as soon as it reboots). The screen flickers for a moment, but it reboots again. We are under quarantine by federal law so I can't get my phone to samsung. Is there any way you guys know to flash it without going into recovery/download mode? I don't mind losing my data, everything is on my drive account, I just want my phone again
Thanks in advance

I think there is no way without entering in download mode or bootloader. Try with this:
When the phone is on, no matter which state, press Vol down + power until it reboots. As soon as the screen goes black, change to Vol. up+power. If this is successful, you can then select Reboot to bootloader to enter in download mode.
If this doesn't work, the next solution is waiting the end of quarantine

Samsung Galaxy a40 stuck on "powered by android" screen

Hello, I have a Samsung Galaxy A40 and yesterday I tried to flash LineageOS (I already have experience flashing gsi's), but when i rebooted the system, it just stuck on the "Powered by Android" screen.
It's not even rebooting, it just stays on that screen until the battery dies. So I've tried to let the battery drain and then booting into download mode after charging it a bit by pressing Vol Up + Vol Down and then plugging it into pc, but for some reason it just won't boot into download mode. What can I do now without having to risk booting into that screen and having to wait another full day again?

Hi,
You probably have to flash the latest firmware for your device.
If the phone freeze on the powered by android screen you can press and hold volume down + power and the phone will force reboot.
To reach download mode you can try this :
Turn off the device
Press and hold Volume UP key + Power Key for a while
Release all key when Samsung logo appears then you will see Android System Recovery
Select Reboot to Bootloader
Use Power key to Confirm

The easiest step is the keys but look like it doesnt work for you.
You should try to boot with different key combination get past the bootscreen, otherwise i suggest you to got to a repair center if you can't
