i have a completely stock lg optimus g, I booted into the recovery and the power button isn't recognized and if i try to reboot the phone it just brings me back to recovery, i can not get back into the phone it just puts me right back into recovery. please help.
Dam weird thing. So you can't use your phone at all? i suggest you to use LG Support tool, go for recovery mode and let it flash the kdz again into your phone so it will run again.
Is your phone rooted and unlocked,with proper cwm or twrp?

Hello everybody,
I was using my Optimus G for one month, I was rooted it and installed CM 10.2, today I decided to install Custom Kernel (this one: http://forum.xda-developers.com/showthread.php?t=2312735) and I did it via CWM (I think that was my mistake). So now I'm getting kernel crash and I can't boot. I know, that I can unbrick my device using KDZ, but how to get into download mode? I'm pressing vol+up and vol+down and than I'm plugging my optimus G to USB but nothing happens. Any ideas? Thank you very much.
Edit: I found, how to enter to download mode, but maybe it's possible to enter to the CWM and just flash my CM 10.2 ROM again so all my apps could stay in my phone?
Edit 2: everything works, huge thanks to Jishnu Sur . What I did? Just enter to CWM (enter to fastboot, using vol+ and power buttons and than, enter to recovery - just click your vol- button many times and than click power button) and flash your ROM again, without wiping any data and etc.
so,
after trying to install cm11 like a madman and failing over and over again , i've installed sphix 2.0. the installation went fine and the phone booted up.
i tryed going into the recovery from rom manager and got stuck on lg screen . did a restart and tryied going to recovery using goo im. faild. and got stuck on lg screen. tryied powering the phone down and pressing the power button and volume up. nothing.
(what is the exact procedure of the button configuration for getting into recovery?)
the status now is that when i try to start the phone the lg screen apears i have one set of rainbow color in the home button. the led goes off and than i'm stuck with the lg logo.
please help! this is the first time that something like this is happaning to me anf i don't have a spare phone!!!!

Do you have ADB installed? If you do, just open cmd...type cd...then type the name of folder where adb is installed, then press enter. Type adb reboot recovery. That should boot you back to recovery so that you can flash what you need.
If that doesnt work...press and hold down the volume buttons(while phone is off)....then plug it in to your computers usb port. Your phone should say download mode. You need to download LGFlashTool, your original lg stock firmware and a dll file to get you back to stock. Hope this works.

you wont be able to get to recovery(trust me i know). Download lgflashtools, your phone model's kdz or tot file (KDZ for E988, F240, tot for E980) and flash. there is a detailed tutorial with all necesary files. I hope you made a backup on your sd card becasue you are about to loose everything on your internal storage. In the weird case that you have an E980 and flashtools does not recognize your device(shows a fail message), use the flashtools for the international version and flash either stock panama or telcel firmware.
The issue resolved using the lg flash tool. Thanks for everybody
Hi all.
I need help from a hivemind. I've got a LG G E988 with E98820B firmware. I've rooted it via ioroot (successfully) and tried to install custom recovery via freegee, and now my phone is not booting into download mode. If I try to reboot it from my PC using adb, I get "boot certification verify" error. Otherwise phone is booting fine into it's stock HK firmware.
So, long story short, I need download mode to flash stock european firmware but I have this strange error. Closest thing to solution of my problem is this thread , but I want something less radical. In case if something less radical exists.
Any ideas?

Did you power off device via home power button? When you power down, then try to power back on just hit the power button then hold the plus and minus volume rocker while letting go of power button.
Yes. It casually boots up into rom. I think I somehow messed up my recovery. So is there any way to restore recovery, or flash custom recovery, without booting up in download mode?

Enable USB Debugging
Connect mobile with PC and select LG Software (Wait for 1-2 minutes and let the drivers install)
Once drivers are installed, Run LG flash tool and start flashing KDZ. It will automatically boot it into download mode and flashing process will start. (If flashing stops / stuck at 4% and your phone is in download mode, remove USB cable, close LG flashtool.... connect USB cable again and restart KDZ flashing)
Tried. Now I can't boot into download mode AND can't boot into rom. And none of my computers see my phone in this state. Any possible explanations for such situation? And what to do about it..
Hello,
I unlocked the bootloader on my LG G4, flashed TWRP and then using TWRP flashed a SuperSU plus a new bootloader for Android M along with the Android M system etc...
The phone is now stuck in a bootloop.
I can no longer get in to TWRP and can get into download mode very briefly before the phone reboots again. My PC can not detect the phone at all.
Can anyone help? Have a feeling I've hard bricked the phone
Thanks, Ben
i have the same issue

wait flastool update for put android 6.0 kdz . antiroll back system on motherboard
Hello Everyone. Someone has got news? Cause my lg g4 stuck on the same issue.
I unlock bootloader and try to install twrp. Via fastboot flash command twrp doesn't seem to get installed. So i try to boot in twrp and then install the img to the recovery partition. All seemed to go fine. When i try to reboot to recovery twrp ask me to root the device. Why not? I leave twrp installs superSu (I think this was my mistake). Now I've a continuous bootloop, even if I simply plug it to the charger. Vol down + Power buttons neither vol up + power doesn't work.
Sorry for bad english
I think one way is to disconnect the battery by disassembling the phone(check Google), then reconnect it and boot to recovery using the correct key combinations. I hope it works.It worked for me.
Install the LGUP tool:
http://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
Install both file.
Download the kdz files:
http://forum.xda-developers.com/showpost.php?p=64298942&postcount=6
This V20A MM, for 5.1 or v20b you have to search.
Power down your phone.
Push and hold Volume Up and then plug the phone via USB to your PC.
The Phone enter the download mode.
Start LGUP, select the KDZ file.
If you choose "upgrade" all data will be obtain, if you choose "refurbish" all data will be lost.
I suggest "refurbish" because for me "upgrade" dont work without fc and system carshes.
Wait around 5 minutes and your G4 is back with MM, clean and fresh.
Thanks hannsheinz for the reply.
I solved this night in this way (very similar to your suggestion):
- I downloaded and installed LG Bridge from the official website.
- I pull out the battery to power off the device.
- I reinsert the battery in the device, without power it on.
- I plug in the usb while pressing volume up button.
- The device entered the download mode and LG Bridge recognized it.
- I press "update error recovery" in Lg Bridge (bottom right in the Software update tab).
- The procedure will take a while according to your pc and internet connection.
- At the end my G4 "breathed again and still breathing"
Very similar to what hannsheinz suggested.
Thanks to all

You need to unlock the Bootloader first.
I used FreeGee on my E975.
After you can access the bootlaoder to flash a new Recovery (i suggest the new TWRP) or use the one from FreeGee.
If FreeGee is not working there will be any other method to unlock your bootlaoder, but this is what you need!
