Wipe ROM and reinstall Android in LG Smartphone - LG Optimus G Pro

Hi, I'm trying to find a way to try to recover an LG D680 smartphone. I have a weird problem with it. It used to get stuck on LG's Logo boot. I used Download Mode and LG Mobile Tool to fix it and update it. Everything was ok but 1 month later this happened again, but this time it cannot get fixed.
I tried to reinstall software through KDZ and flash tools (2014) in Normal and CSE mode. I tried Iusacell (AT&T) images (V10A_, V10B_, V20A_ and V20B_) wich are Jelly and Kitkat versions of images. Last I tried to reinstall with V20A_ Factory Free image and still problem, but now there's another problem. It seem that there are not really hardware issues since device is correctly recognized in Windows System, can enter Download Mode, LG Flash Tool can still manipulate hardware (Install, reboot and finish install). The new problem is that even after reinstalling any of the images it keep looped and stuck at the "Android Hard Reset" icon, the one of the Android with the red triangle.
I tried using fastboot and adb but devide is not recognized by fastboot device even after installing drivers.
Is there another way to completely wipe ROM and install System and Boot clean? I already have system.img and boot.img files, but can't find a way to do this nor what I do works.

If it is looping on LG's boot animation, then you should boot into stock recovery and do a factory reset from there - saved me from sending my E988 to service last time I flashed stock. Try one of these recovery combos: Vol Up + Power, Vol Up + Vol Down + Power, Vol Up + Home + Power, one of those should work. My E988 uses Vol Up+ Power - have to press both while device is powered off, and keep them pressed until capacitive buttons flash twice. Not sure how will that work on D680 though (is that a G Pro Lite?)

Yep! It's an G Pro Lite. I'm still trying some of th combinations. What is stock recovery? Should it show more options than just hard reset?

If it's anypart similar to ones found on E98x, it will have only hard reset, update install and reboot options. I really don't know much about Lite series, probably there is more info about recovery in their subforum here.

Boot loop after returning to stock (Solved)

So i've had this a few days and was running with CM Nightlies and TWRP 2700.
I decided to return to stock through the LG Mobile support tool, but now i'm stuck in a boot loop.
I'm unsure of how to enter recovery, as the instructions in the "All Things Guide" are a little confusing and don't seem to work.
I can get into download mode, and have tried running the lg support tool again to no avail.
Pretty sure i just need a factory reset to clear the loop, but how can i do this without recovery or adb?
Thanks
EDIT: Nevermind, found a tutorial on youtube showing how to enter recovery

You can get to recovery with Physical buttons
Holding Vol Down + Power
When LG logo appears release Power while still pressing Vol Down
While still holding Vol Down, press and hold Vol Up and Power
You'll see a black screen with a "Factory hard reset" button", Press the Power button a few times until it boots into Recovery

[Q] Can't boot to recovery

I have a F400K G3 (Korean Olleh). It's rooted and bumped. I flashed the bumped TWRP image via Flashify and rebooted recovery via Flashify. It works. But when I try boot to recovery from a complete shutdown. It just boots into safe mode. I did exactly what was stated in the Bump thread (Power+V. Down, when logo appears, release then press again quickly) and also tried substituting V. Down button with V. Up, but it still wont boot to recovery. It just keeps going into safe mode. The video provided in the thread was using an AT&T model so maybe it differs from every variant. I want to know if I'm doing something wrong or the instructions are wrong.
Thank you.
You tried without releasing? Just keep holding buttons

Do you get to that factory reset screen?

I have tried it as well without releasing. Does the same thing. And it never shows the reset screen. It just goes directly to the boot animation. Rebooting from Flashify also doesn't show the reset screen but it does get to TWRP. But I need to boot it from complete shutdown because I'm gonna test a Flashable zip ROM without root so rebooting using Flashify would be impossible.
Bump.
Seriously. Anyone?
I am subscribing because I have the exact same problem. I have tried every key combination I could find for the G2 and G3 but no luck...
This is exactly the kind of problems you get when using stuff like Flashify. The holding of the buttons etc you mentioned should work. Are you sure you aren't connected using a micro usb?

No, I am not connected to USB. If I reflash the recovery using ADB will it work? But I do have some worries because I'm using KitKat bootloader on a Lollipop Stock-based ROM (here) and I think I may get some errors.
It's not very important right now because I have root now and can reboot to recovery using Flashify.
I think all korean models cant enter recovery via hardware keys, mine is F400L and have the same problem.
Untouched LG G3
I have a completely untouched LG G3 uk version only official software no root etc and mine won't go into hard reset mode. I have tried 3 or 4 times it always goes into safe mode

Turn off the phone completely. Press and hold Power and Volume Down. When the LG logo appears, release. After a split second, press volume down and volume up. White screen asking you to reset will appear. Press Yes two times using Volume buttons.
UP!!!
Any remedies? I justed from stock to cm12 LG g3 F400L..
Cant go to recovery mode. Cant flash anything..
Same prob,always going to safemode.f400k rooted,cloudy2.5
i've Lg g3 F4ooL and using Resrruction remic 5.5.5
I stuck in a Bootloop and my device is also not booting into Recovery or safe Mode.
Lg flash Tool is also not Connecting to my device in Downloadmode.
I think There is NO solution At ALl
Has anyone solved this issue?
to get in recovery on F460s, worked on mine, Press Vol-up + Power, as the logo appears release the keys and press Vol-up + Vol-down, you will boot into recovery.
I have the same issue, cant go into recovery using hard buttons on F400K. Any one able to succeed in this?
Same issue on LG G3 F460S, no combination of power + volume buttons + releasing them and pressing again when LG logo appears works. The device go straight into booting system and gets stuck. Is there any other method - maybe short-circuit some pins on the motherboard, to boot into recovery or do a system reset? Please...
OK, turns out that the combination is different for Korean models of G3, as misbah711 wrote, volume UP + power, when logo appears, release and press both volume UP + volume DOWN. If that does not work, try again, but release only the POWER button and press immediately volume DOWN (while volume UP was held all the time). Also, I first tried it without the back cover, as I have to remove battery to turn it off, did not work. Then with the cover it did, not sure if it's an important detail or not.
However it's not the end of the story for me. An image with Korean text appears, and nothing. No combination of power and volume buttons pressing does anything. I'm attaching the image. Also tried a web service to do Korean OCR and then used Google Translate - does not make any sense. Could anyone advise how to proceed and do a factory reset on this device? It won't boot into the system (gets stuck), no adb or any other communication with it.
Edit:
Turns out that when the Korean text appears and I connect USB cable to my PC, adb works correctly. Typed:
adb reboot recovery
The phone rebooted into recovery and now I'm doing a factory reset on it. Looks like all will be fine.
i have d851 on stock kitkat. I flashed TWRP and Philz but no way i can get into recovery mode. it always goes to fastboot mode no matter how I reboot into recovery. Now i am looking for stock recovery image. or a way to fix the twrp/philz. ROM boots just fine.

[Q] F180 (vol up + power) does't work

Main information. F180, bootloader unlocked with teenybin, I'm on resurection lp rom.
Everything worked fine but I accidentally flashed the wrong file, now the phone is in boot loop. Though that is not the problem (I know how to fix it).
The problem is that there is no way I can access recovery. This happened to me before but I got lucky - computer detected the phone while it was in bootloop and I was able to use (adb reboot recovery). Next time I got lucky some kind of green screen showed up and from there I was able to go to recovery. Now i know that the most obvious way to go to recovery is through bootloader (vol up + power) but no matter how many times and in what diffrerent ways I try it I can't boot into bootloader it simply starts booting the rom... I am frustrated and have zero ides. Maybe you have some. Thank you in advance.
P.s.: i held down the power button for over 1 minute before attempting. And also download mode works.
If you can still boot into download mode you can try to flash the original firmware with the LG flash tool:http://forum.xda-developers.com/showthread.php?t=2797190
Don't worry you can use it for the LG Optimus G too:fingers-crossed:
Thank you for the idea, but I managed to solve my problem the same way as before. Use adb while the phone is in bootloop.

[Q] LG G E988 can't boot in download mode

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..

H815 stuck in bootloop, no download mode or recovery

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
