[Q] LG G2 bootloop, No recovery mode, only download mode

Hi guys, (LG G2, Rooted, had twrp but now its vanished?!)
I managed to get my LG G2 into a bootloop. I was replacing bootanimations and rebooting and testing them out. I finally tried this 1080p boot animation that looked sweet. Once the device rebooted it would show half the boot animation and then reboot. I had twrp installed but now every time i try to access it it just ignores the hotkeys as if it doesn't exist anymore. I can only get into download mode if a usb is plugged in.
All i need to do is flash TWRP again so i can flash the stock bootanimation back. I do not want to do a fresh install as I have many important files (i know i should have backed them up). I have tried to access my phone via adb using windows commandline tool whilst in download mode. however, adb doesn't find my device (I was going to attempt to push the stock animation back).
Please help me guys i need my phone to be working by monday as i have work! thanks in advance

1. If you connect your phone to PC, what happens?
2. I also had trouble accessing TWRP, so I did the "Factory reset" button combo (Don't remember what it was) and when I slided to confirm, twrp booted. From there I think you have adb and can fix everything.

To get to TWRP, hold the power button until the phone turns completely off, then turn on the phone while holding the power and volume down buttons, then when the LG logo pops up, let go and re-press those buttons. When prompted for a factory reset, press the power button. Works every time for me.

Alone i used lg flashtoolnow,its ok. I didnt click factory reset i assumed it would delete everything? With lgflash i have restored system and everything is how i left it.

First off, you'll need to make sure your phone isn't plugged in or it won't work - I'm afraid if you can't enter recovery you'll have to go back to stock. http://forum.xda-developers.com/showthread.php?t=2432476

Try to flash the Kitkat baseband or if you are fully stock then i suggest you to flash the KDZ to go back to full stock(http://forum.xda-developers.com/showthread.php?t=2432476)
If you still have important data like pictures or what then do normal flash. Use the Android version you also had as stock and use that as KDZ. If you are not stock then can you reach TWRP?
and what did you do before that causes the black screen?

Stuck with the LG logo. Nothing happens in download mode
Hi All, not sure if this has been answered prior. This is what happen, I wanted to flash SOKP so I backup my phone and saved to PC using Titanium. I have TWRP installed.
Boot Into Recovery Mode and Wipe Data,System,Cache,Dalvik
I restart so I can flash the SOKP Rom and all I see on my phone is the LG logo. I try to restart using the Power and Up button, but it just sits in the download mode saying "Firmware Update" with no movement or action.
The phone is unable to turn off now. This is my first go at Flashing a Rom. Any help or suggestion would be greatly appreciated. Thanks in advance

Hey, I have the nearly same problem with my G2 running CM12 also installed recovery
But I can't reboot in recovery neither with the factory reset buttons, nor manually with SDK Manager, because the device is not found.
So I can just reboot and it shows the CM boot image, or get in the download mode.:crying:
Any suggestions?:fingers-crossed:

I was in same stuation before 2 months send to warranty.
If rooted you can use adb shell with su and push partitions with "dd" while staring (stuck in lg logo)

Help!!
I have boot loop, only download mode accessible, device not found on adb. When I try LG FlashTool, instead of using the KDZ file I provide, it starts downloading some other firmware at times, and at times it says your software is up to date. What do I do? :|

I had encrypted my other G2 cuz I never used it but wanted to use it so I turned it on
and behold, it wanted password that I forgot. I live nowhere near a Sprint store so I started

Thanks alot i figuried it out

same problem
Hi guys,
I have the same exact problem, restored my rom with LG Flash tool 2014, but now it's always asking me this pin/password. And I tried all combinations with volume up/down and it's impossible to go in recovery, what can I do? My LG G2 is a european model 32 GB

this is the screen I'm always getting

Same Problem Here
Hi,
I'm having the same problem.
I have an LG D802. I was on CloudyG3 with TWRP recovery. While using the phone, I noticed a yellow tinge in the right side of the LCD. So I figured, I'll show it to the service center and get the issue sorted out. Obviously, I couldn't take it there rooted and on a custom ROM as they would annul my warranty otherwise. So I decided to unroot it using the LG tools. (I have done this before too. But I did not face any such problem back then).
This time, it is taking me to the screen and asking me to enter a pin/password to decrypt.
I tried booting into recovery using the old method (volume_down + power and LG logo flashes, release and press power again, then 3 times power) and also tried another method as recommended by someone above (volume_down + power till LG logo appears and then release power and press volume_up). None of them work now. In the first method, the screen just goes blank for a few seconds and the phone reboots while in the second method, the phone boots into safe mode.
Kindly advise on what to do. I am stuck and my warranty expires on the 18th of November.

Problem Solved
Earlier when I was using the Flash.Tool.1.0.54, it wouldn't ask for region and language in the pop-up. It would just open the LG Mobile Support Tool and then I manually selected the Start Upgrade button to flash the phone. The problem with this was that on boot it would ask for pin/password. I couldn't even boot into the stock recovery for some reason.
Then I used the LG Flash tool 2014: http://forum.xda-developers.com/showthread.php?t=2470207
There was a region and language pop up and it proceeded to install the firmware.
But on boot, it still asked for the pin/password. So I tried to boot into recovery and it worked this time! Pressed the power button 3 times and it wiped my phone.
On reboot, the phone worked perfectly without asking for the pin/password. But, now it was reading my internal storage as only 16GB. I followed the directions in the link provided by @Alexxxx to repartition the internal storage in my phone. Here is the link once again: http://forum.xda-developers.com/showthread.php?t=2470207
It worked perfectly for me.

Recovery files from other phones?

[Q] Lg-D802

Hi,
I am struggling with this damn LG D802. A friend brought it to me to unlock it as he said.
when i turned it on , it boots and it stops where it asks me "Enter pin/password to decrypt"
So i thought ok, i would enter recovery and wipe cache. That's my problem, i can't enter recovery mode.
I tried power + volume down , and when LG logo appears then i release and hold them again , nothing. I also tried volume down + power and when LG logo come , i release them and pressed volume up+volume down. Nothing. And some other combinations but still nothing.
The next step was to reflash it, so i used LG flash tool 2014, i download the right kdz file , and flashed procedure went fine. But on next reboot same problem " Enter pin/password to decrypt".
There are no files that i need from the phone , just to make it work again .
Any ideas?

In flashtool 2014, keep the cdma option in the menu, select CSE flash. It wipes everythinG. If it's not the sim card your device should be fine,

LG D802 fastboot problem

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)

Yotaphone 2 - another bricked phone after update

Hi guys,
My Yotaphone 2 is currently stuck in a boot loop (shows android logo, then black screen, repeat) after a software update. I can get to the 'Downloading...' screen via power + vol. key and so have tried adb/fastboot as suggested in other similar threads. ADB can't see the device, which I guess is probably normal since it isn't booted up, but fastboot seemingly can. I've tried flashing the TWRP recovery which seems to go through fine on the PC end but doesn't seem to do anything at all on the phone itself. Calling a fastboot reboot gets the phone back to the boot loop and power + vol. goes back to the 'Downloading...' screen.
I've also tried using the Yotaphone flashing tool to flash a full android image - this also looked like everything was operating OK on the PC end but didn't seem to change anything on the phone once the process was complete.
Is there anything I'm missing or anything else I can try? Any help/ideas much appreciated!
Cheers.

Do you have any idea what caused the bootloop? (maybe installing xposed or something?)
When you keep vol-up pressed at (not after) the moment the phone vibrates during power on, you will end up in TWRP recovery. There you can at least wipe->factory reset. Don't do this if you have stuff on your phone you'd like to keep though. (you can try to rescue/backup those by trying "adb pull <path_to_file>" when the phone is booted into TWRP)

It was caused by doing an OS update (wasn't rooted or modified), I've only since tried installing the TWRP recovery and using fastboot to flash an official image to fix the looping. Flashing TWRP appears to work according to flashboot but holding the volume up key at the vibrate on power on doesn't do anything sadly.

Maybe I should rephrase: the vol-up should already be pressed once the vibrate starts. For a timing-insensitive, fool-proof (no pun intended) way you can enable bootloader (like you did before: you get the Downloading... screen). Then keep vol-up and power pressed together, after 15 seconds the device reboots hard, keep both keys pressed until you see TWRP 'curtain' screen, then release.
Did you try to use the YotaFlasher Windows application to reinstall an official ROM and restore factory defaults? You can get it from here, also download a ROM for your region here.
