[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:

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? :|

Sir, I really appreciate your concern, but believe me it's a hard brick case, so I cant access any usual boot neither fastboot nor recovery.
I wish someone tells me how to unbrick it.

Plug usb and try two vol button in same time, tell me if vibrate, if not let it charge during 1 hour and retry

There is a probleme, you've just flashed the swift ROM, not really a reason to brick...
And the swift have same partition like the storm.

When i googled my problem i found the same happend with oneplus one phones,
The problem was hard brick due to wrong rom, and windows can see the phone only as Cualcomm hs-usb Qdloader 9008, same as my case. And the problem solved for the oneplus one, so I have some hope that my phone will come back to life.

Hi I have a similar problem, I installed the correct cyanogenmod and recovery and it was working fine, but after today's update it shows the bootup logo and then gets stuck in a black flickering screen.
I can't seem to be able to boot neither to the recovery nor to the fastboot mode, no volume key combination seems to work.
All adb says is the device is unauthorized and fastboot doesn't seem to be able to even see the device.
I tried the vol+ and vol- and power and it does vibrate, if I use the vol+ only it seems to get stuck forever on the vendor's bootup logo and the device doesn't seem to be seen neither from fastboot nor adb.
Is there anything else I can try to unbrick it or is it gone?
Thank you in advance for your help

Have you tried to hold together for about 20 seconds the power button and sound button less ?

Strugglin
I have same problem, either stuck in bootloop (to the wileyfox screen and back to black) or just off. ONLY red charger light shows when I plug it in. Fastboot not working, recovery boot not working... NOTHING is working. On top of that I haven't even installed any roms, not rooted etc. All I did was reboot when it froze on a silly game I didn't mean to open WTFF

wileyfox dead
I have the same problem, bootloop, qualcomm 9008 no fastboot or adb recognition. I'm guessing was the OTA update cos I didn't install any roms at all. TOTAL waste of money, zero support too. It's a non-starter DO NOT BUY!!!!

Same here , interesting is the different device status between linux and windows,
at debian it's "offline" - at windows "unauthorized".

Cannot enter recovery mode after updating CM13 nightly

Hey guys,
I feel totally stupid for writing this post but I'm actually out of ideas how to get out of my situation. Also I didn't find any comparable topic here on xda. So let's hope you can help me and a big thanks in advance!
First of all i have a flashed D802 running TWRP and CM13, which worked well the last weeks. I thought about updating to the todays nightly as it is already a few weaks since I did my last update. I downloaded the nightly via the CM downloader and started the installation with running phone. It rebooted into recovery mode and installed the nightly without any problems. After the installation was completed the phone automatically rebooted and this is where the problem starts.
I am stuck in "bootloop?" at the CM logo. It is not automatically restarting after a while but just loading and loading and nothing further happens. I am not able to enter the recovery mode via the factory reset (Pressing Vol Down + Power, releasing after the lg logo appears, pressing and holding the power button again).
This never happened to me and as I am not able to enter TWRP I am not able to install a previous release or a backup. What am I doing wrong this time and what can I do?
Thanks for your support!

have you tried flashing a stock rom?

Actually I don't really know how to do this when I'm not able to enter the recovery mode? Is there a certain way to do this?
In the meantime I managed to enter the recovery mode / TWRP via a mode I don't know how it is called. I pressed vol down + pw btn, released after the LG logo appeared and pressed vol up + vol down. I guess my userdata is deleted by now, which shouldn't be a big deal but I am getting redirected to the recovery mode. I tried to install the yet working CM13 nightly but it has the same problems now.
Now I have two questions:
Does anyone know which part of the system is broken now / which part I need to update in order to get my phone back to life?
Is the download mode working if my phone is rooted? I am able to enter this mode.

yes you can enter the download mode: turn down your phone, press and hold volume up button and connect the usb cable, release volume up when your screan shows dowload mode.
then follow this tutorial to restore your phone back to stock http://forum.xda-developers.com/showthread.php?t=2432476

Flashed wrong image. ZUK Z1 is bricked.

Hello everybody.
Clumsy idiot I am, I flashed the wrong .img through Flashify and now my phone is bricked. Here's all I know:
All I see is a boot loop, phone turns on (with bootleg and vibration) for a second, then off, on again and so on.
- TWRP installed, but not reachable.
- ADB not working.
- QFIL not recognising the phone (drivers installed).
- I have no logs to post.
- No way to operate Volume/Power combinations because the time the phone reboots is less than a second.
What can I do to save it?

Take it to service center they dont even know what happan and repair or replace your phone as my expiriance same done on my old infocus m2

Keep pressing volume up + volume down and power button so u can enter twrp...
Or
Switch it off completely and press volume up and connect it to pc to enter fastboor and flash stock rom using fastboot...
I think u can revive ur phone back as its booting means the bootloader is still present...try entering fastboot

Use QPST and flash ZUI with that. I unbricked mine with that.

Because I accidently flashed one plus 1 twrp in zuk z1. Now device only shows zuk logo and after that complete black out. I also tried the solution of hardbricked( Volume up button) phone but can't fix this problem. I am not able to go to fastboot mode. Is my device is hardbricked or softbricked? Any one suggestion will be very helpful to me and thanks in advance.

It seems there is a solution. Keep pressing the Vol+ Vol- and the Power Button until the phone switches off. The phone will reboot. This time when you press Power Button, it will not restart. Hope I helped you.

Stuck in fastboot mode

I dont know what happened but I rebooted my phone today and it booted into fastboot.. I cannot in any way get it to boot normally. The buttons are not being held down and I have tried to pull the battery.. I dont get it, anyone else have this issue and fixed it have an idea??

Was it stock (including recovery) or modified?
I would try to fastboot the TWRP over and then boot into that (Power & Vol+). But then... I seldom run stock.

No, it wasn't stock and I dont know what happened.. I was running the latest CM13 and rebooted this morning and it freezes up with the ASUS logo and saying "Fastboot Mode!!!" at the top... I've tried flashing twrp via fastboot but not getting anything.. I need a copy of the stock firmware with the boot system and recovery image in it but I'm having a hard time finding it.

Then it booted normally. Everything stock.

Phones boots into fastboot mode in two situations
1. Pressing vol up and power button simultaneously for rebooting
2. Your phone doesn't have recovery AND any OS installed
I guess your vol up button is constantly in pressed state.
Second situation cannot occur unless you wipe your system and recovery manually. So you are in the first situation
Your phone's vol up button is constantly in pressed state or electrically shorted may be due to water entering the case
Solution: You will have to open your phone's case and clean the area near the volume button. I guess you had opened the case/body and didn't fit it properly.
