Hey everyone,
so here's my situation:
I unlocked the bootloader for my G6
I activated USB debugging and OEM unlock in developer options
I then flashed TWRP 3.4.0-1
Now the phone is stuck on the boot screen, when I hard reset (power button + volume down, then pressing power button again when G6 logo appears, then selecting "factory reset" and "yes" twice) the phone does not boot into TWRP but instead goes to the boot logo again and nothing happens. I tried leaving it for a while and it stayed like this until the battery ran out. When I plug it in, it starts the same procedure immediately. When I connect it to my pc, I cannot manage to flash anything because I can't boot into bootloader because the phone is not detected (my pc doesn't play the usb plug-in/unplug sound).
So my question really is: Did I kill my G6 since I am unable to flash anything or is there still an option to get bootloader running again? And yes, I did try the unbrick method under https://forum.xda-developers.com/lg-g6/how-to/lg-g6-unbrick-method-t3935924 but I get stuck at the point where you need to click "download" because my phone is not detected. I also heard about the method of shorting the pins beneath the flash but I don't know how to do that...
Any help is appreciated.
Hi,
I had the same problem and finally solved it by using the release of TWRP found here : https://forum.xda-developers.com/t/recovery-twrp-3-1-x-stable-official.3627595/
After flashing TWRP I followed those restarting steps :
Hold vol down + power for 10 seconds and your phone will power off.
Hold vol down + power / release power when the LG logo appears and then immediately hold power until the Factory Menu start
Menu select Yes
Confirm Yes
TWRP boots
Hope this will help
Edit : A more recent version of TWRP compatible with LG G6 is available here : https://forum.xda-developers.com/t/recovery-twrp-v3-2-3-1-for-h870-h872-us997-unofficial.3828254/

I have lg g2 sprint version. I have unlocked it by following a tutorial on youtube. On the ui there was a message that there is software update and i tapped to install it, but it was stuck on fastboot mode started udc_start() so i followed tutorial from a forum and fastfbooted boot aboot recovery and laf, but forgot to run fastboot reboot and turned off and on the phone. Now when I try to start the phone it shows the lg logo and after that only the led is flashing no matter if it's charging or not. Any ideas what to do? I have plugged it in to power it, but I am not sure whether it's charging now.
I can enter in download mode by pressing volume up and power button, but I don't have pc near me to try to flash to stock.

The situation after a couple restarts is:
When I put to charge the lg logo appears and the led is flashing from yellow to blue
if I hold down and power button it says "Recovery mode. Loading..." and nothing happens
If I hold up and power button it enters download mode
Can I charge the phone in order to flash it to stock?
p.s. I am turning it off by holding the power button for ~20 sec
Hey guys. I bircked my LG a couple of days ago and now it's in:
[810] fastboot mode started
[860] udc_start()
I cannot enter download mode because the phone will not shut down. When pressing and holding the power off button it turns off for a mere second and then the LG logo comes up and i get into fastboot again. The phone will NOT turn off.
When I connect it to the PC it is not detected as qhsusb_bulk in device manager but as a CMCC ADB Device>CMCC Composite ADB interface.
Any help is appreciated.

hold pwr button longer, don't let it go when LG logo shows... only then the device will power off completely...
after that, search on how to enter the recovery (depending on your bootloader - see dorimanx kernel thread op)

if you have a twrp recovery - it will first show "factory reset", you say "yes" 2 times and it will enter twrp (it will not wipe anything)
if you have stock recovery - then don't press "yes" in the reset screen...
did you by any chance flashed a kernel recently?
fastboot error message is commonly shown when people flash the kernel which is not for their variant - and this can easily be solved with flashing the right variant kernel... (i.e. you have d802 variant and you flashed kernel for d800 variant and vice versa)
I had an indian G2 D802T with stock lollipop 5.0.2. At that time I was able to use the hardware keys to boot into the Hard Reset mode(vol down + power). Then I had it rooted using lg one click root tool and after that also I was able to use the hardware key combination. I then followed this guide http://forum.xda-developers.com/lg-g2/general/complete-guide-convert-d802t-d802-t3184830 to install recovery and cloudyg2 3.3. The phone now shows as D802.
For some reason, now I cannot use the hardware keys to boot into recovery. I can boot into the recovery using an app. These are the combinations I tried:
1. after phone shutdown, press vol down + power until lg logo comes. Then release them and press them again
Result When the lg logo comes and I release the two buttons and press them again after sometime the phone turns off. During this time the led on top lights up as though booting into phone until the phone turns off.
2. after phone shutdown, press vol down + power until lg logo comes. Then release only the power button and press it again(keep pressing the vol down).
Result Same as above.
3. press vol down + power until lg logo comes. Then release them and press vol up + power
Result The phone boots into safe mode.
To install cloudyg2, I had to use an app to boot into recovery (after installing recovery) as manually restarting the phone (through power key) would result in the phone getting stuck at LG logo at boot. ( please see my comments on the above link on page 2 for more details).
I need the functionality to boot into recovery using the hardware keys in case the os fails to boot after installing some zip.
Please help!!
Update Just noticed in the ROM Manager app, under the installed recovery it shows both CWM and TWRP. But shows current recovery as TWRP. Is this an app issue or the reason for my above problem?

You can't update modified firmware i must be stock for OTAs. If vol down + power key don't work, try this method (make sure battery is not drained out) - take your phone while it's off, press and hold vol down and vol up buttons together and plug it into computer via USB - it should boot in fastboot mode.
I was messing with my P10 Lite and I accidentally wiped the Vendor partition (not sure if I wiped anything else) with TWRP. After the phone rebooted it said something about a critical error during boot and went into erecovery. It gave me two options( I don't remember the second one) and I chose factory reset. It started doing it's thing but I guess something went wrong because it wasn't able to boot and it started to bootloop.
I managed to get into fastboot once. The bootloader and FRP should be unlocked but I am not sure as I think I semi accidentally used the command to relock the bootloader in the hopes of it doing the automatic low level factory reset. After that restart, the phone wanted to boot up but after the Huawei logo it went into the EMUI logo which I've shown in the pictures. Now I can't use any button combination and can't enter any menu. I also can't shut down the phone as it bootloops into the EMUI logo after I press the power button. I opened the phone and turned it off by detaching the battery cable but after holding the power down key and plugging the usb cable into the phone it still boots into the EMUI logo right after the Huawei logo.
I guess not being able to enter fastboot is the major issue and after hours of googling I am yet to find a solution.
Edit: I am a newb!
Please help!
Why did you delete the vendor partition, you could try plugging the phone into your computer and checking if you can do anything with fastboot while it's showing emui logo?

Dload method. Put sd card in other phone or some card readers and put appropriate files.

I've already tried that. I've placed the appropriate files into my SDcard but I can't use any button commands including volume up+down+power. When I press them my device just boots into the EMUI logo and nothing happens.
Edit: It boots into the EMUI logo even if I only press the power button. Pressing volume down + usb also boots me into the EMUI logo

I measured once and not trice before cutting... I was also not paying enough attention/in a hurry...
Power OFF the phone.
Press and Hold VOL Down and connect the phone to PC via USB cable. The phone should boot into Bootloader (fastboot mode). Does this method work?
or try this:
Press and Hold VOL Up and connect the phone to PC via USB cable. The phone should boot into eRecovey mode and then then select "Download latest stock rom and install".

Ok, it seems like not all is lost about my phone. I managed to get into fastboot. In my situation, pressing volume down + usb cable while the battery was plugged into the phone did not work. That was before I opened up my phone's case and disconnected the battery cable.
As I mentioned before, I had opened my phone and disconnected the battery cable because that was the only way to shut it off.
What I did after I disconnected the battery cable was the following:
1 - Hold volume down and don't release it
2 - Plug in USB
3 - Plug in the battery cable into the phone's mobo.
That booted me into fastboot. Right now, the phone says my bootloader in unlocked and my FRP is locked. What would be the best way to flash the new stock OS on my phone?

I have downloaded THIS and THIS for the new OS but by talking with Alexxxx1 in THIS discussion I learnt that Huawei has implemented a security patch in their latest update, which I've most likely installed, that prevents you from rolling back your OS version. That means I need to install the .386 version, which should be the last if I am not wrong, instead of the .378 correct? Though I heavily dislike patches like this I guess I can't do anything about that...
