Hello, i need help:
I used my g4 with a nougat custom rom with no problems, i flashed the n bootloader and used it for months, yesterday I decided to do a factory reset in the phone settings.
The phone rebooted in twrp and I did the factory reset.
But from then, the device was stuck in twrp without possibility to boot the rom!
So i flashed another nougat based rom, the installation is fine, but the issue persists.
Now I'm trying to restore the phone, but I don't know what to do... I can only boot in download mode... Twrp is no longer working...
Please, help me, this G4 had to be a Christmas gift...

Thank u. But the new method is only to upgrade or downgrade from 5.0 to 6.0. But not for upgrading from 4.4 to 5.0. Then how should I use? for kdz method,he mentioned the same LG flashtool 2014 method. ?????

you are right. use the lg flash tools 2014.
have you selected CSE flash?
are you using the correct KDZ for your cell?
what OS are you using?
have you installed the LG drivers?
what about the cable?
I personally do a hard reset before flashing a kdz.
I just updated my phone from LP to MM using the LG flash tool without a problem.

yeah. i am selecting CSE flash only.
I am using correc kdz .
My lappy is running on windows 10 and my phone is on kitkat v10n
The cable is 100% perfect as i flashed my g pro few days ago with the same laptop and same cable.
and coming to hard reset, I am unable to reset the phone. Just now I noticed that after selecting reset I went into black screen and can see "Fast boot mode" at the extreme top left of my phone. I switched it on and it booted back. What might be the problem.?

windows 10? I'd use windows 7 or 8.
your problem is not the flashtool. search for some tutorials about how to fix fast boot mode.
I dont understand why this happens because i follow the rules exactly.
I was using MM with TWRP+Root.(Not kingroot or other, just SuperSu 2.52) I was flashed .zip file from Xda. I mean i was using L and after that .zip files pops out for MM, i just simply flash the MM zip file and got it worked.
After flashing kdz file with LGUP now my phone stuck at twrp. Now i stuck at twrp. I tried to restore my backup on external_sd but didn't work either. Any ideas?
LG Up can't wipe twrp , so tried flashing again with LG Flashtool with lastest driver.

I had same problem with it being stuck at 60% what I did was not to press cancel or unplug but pressed retry and it worked. Also change the language to English and the question marks will disappear.
As for the device disconnected issue i'm not sure how to solve that one you could try running flashtool in windows 7 compatible mode.

Solved my problem. The problem was using LGUP firmware to go back to stock. LGUP Doesnt work if you had root+twrp. Flashed kdz using the Lg Flash Tool 2014 ( I had really more problems when doing this but i made it.) Phone back to normal.
Hi guys
LG G3 looping on boot screen every time,
I had TWRP with fulmics rom installed and one day it just shut down, i tried turning the phone on but it shows the lg booting screen and then reboot, and it goes on like that, I tried installing different roms but always the same problem, i
should mention that i tried cloudy rom and i did actually work but when booting the phone it had this problem that the wifi and bluetooth won't activate, i searched on the Web and a lot suggested that is a battery problem,
so i thought the previous rom worked well so let's change this rom,I installed a lot of roms and the boot looping problem shows up every time, so i thought **** it let's get the stock firmware,
and when resetting the phone to stock firmware it's stuck in the rebooting phase at the end, boot loop again, and now that I've lost TWRP i only have the firmware solution that is not working, this too was mentioned to be a battery problem,
and i bought a new battery and nothing have changed,
tutorials that didn't work for me : http://lgg3root.com/lg-g3-stock-factory-firmware/ http://unbrick.itcse.com/unbrick-lg-g3-stuck-on-factory-reset-2/
is there anyone can help please ?
so did you try to change the battery or not?

I just bricked my g4 by flashing a kdz but then the kdz fdailed and after rebooting the phone it was only able and was immediately going ( after the lg logo) to the download mode/ firmware upgrade. It was not recognizable by LGUP. I added some dll files to help fix that LGUP issue but i dont know if its working because by g4 cannot be detected by LGUP. Going in recovery to factory reset and selecting Yes 2 times only freezes the phone.

The process stops at 11% at PrimaryGPT with the phone showing no signs of upgrade ( exept the green com port ) - 0%
The phone has (or at least had) v29A polish nougat rom

I have exactly the same problem. I can flash v20p KDZ, but reboot still failed (stuck at LG logo).
Then I enter download mode, I can flash v29a tot polish nougat rom , but reboot still failed.
I notice that the LED is not flashing at LG logo screen.
Is there any other way to try?
Thanks

You're sure that you wait long enough? You check how the process is running on the phone "flash status bar" while flashing in download mode screen?
You try to boot on recovery and factory reset?
I waited for 5 minutes.
The flash process completed 100% successfully.
I tried to boot in recovery and confirm ‘yes’ twice, but nothing happen.
If I flash android 5.1 and flash LG’s MSM big core disable tool tot, it can boot successfully.
So I guess my main board may have problem.
Now I need to see if there is an DIY way to fix this.

The only kdz file that worked for me to go back to MM 6.0 is H81520p_00_0314.kdz and i have tested alot of kdz and tot files too. Only this one kdz worked. I did a little Tutorial how to go back with this kdz, see on Page 16 .....22

This is the dll file i´ve just extraced from the H81520p kdz.
But this dll is normaly only needed when you get Errors in LGUP while flashing or flashing stuck on 11% or 22% etc.

I´m sure this wont help you out, but try it. Please point to the Refurbish tab in LGUP, the Upgrade won´t work.
My other Idea is to crash the Phone totaly, delete all Partions via TWRP and restore them to a working System.
