I got this Korean F500l model so I tried root. I downgraded with lgup, but after it, it shows lg logo then black screen then one more time lg logo then android screen which shows when android update. I downgraded one more time and downloaded another version of it but its same. And in lgup, it shows the version as F500l21a. Is there solution for it?:crying:

My G3 F400L was already on stock and rooted. However, i read that if you modify the build.prop ro.model to a K variant and flash the K variant firmware you will end up with the an F400K - which would be better for me frequency-wise.
After 3 attempts using the TOT and DLL method, i'd always get a failure aftter 15 secs. For the first 2 times i could reboot normally into the same OS.
But on the 3rd failed attempt, it would go as far as the LG logo then the screen would go black with the pilot light glowing on and off.
Please help! I've been looking for a kdz for the F400L but couldnt find any. i plan to flash using LGFlash Tool 2014.
Appreciate any immediate advise. Thanks!

Hello Everyone,
i need help reviving my lg g4 and i search all the forms but no avail. I just got a G4 4 days ago only it was running lollipop and working fine i just check for the MM update in phone but there was no update so as i previously own a lg g4 with flumics rom so i decided to flash a kdz with MM update. I see my model no. as h815 so i download H81520h_00_0516.kdz and flashed it through lg flash tool 2014 it flashed without no error but after the flash i got no display in phone just blue led flashes and i hear lg boot sound and then just nothing on phone display it switched off itself. I try to go into hard reset but again no display i try to go into download mode again no display. I attached it to pc it shows LGE Mobile USB Composite Device. Although it shows in lgup tool as H815 and port no. as well.I search my model no. through IMEI i found that it is actually F500L model as i see Korean as it flashed 1st time in download mode. After some research i manage to go into download mode by removing the battery and attaching the phone to pc as it shows empty battery icon so i inserted the battery by pressing the vol up button it goes into download mode. So i try to flash the right firmware which is F500L20u_00_0504.kdz bhut lgup says it invalid kdz i try to flash it through lg flashtool2014 but it says cannot connect to server and failed with contact system administrator. Although it flashes H815_EU_10C_00.kdz and India H818N10d_00.kdz firmware's but those give no display at all i tried it with Lg Bridge as it shows update avalable F500l and it download it but failed to flash it. I try flashing korean tot file LGF500LAT-00-V11d-LGU-KR-SEP-21-2015+0.tot through lgup tool but again it said invalid tot file So friends i am stuck and looking for 5 days to find any solution So anyone can please help me i just used it for 1 day . So can anyone help me.
You have to edit a F500L kdz with a hex editor and replace every F500L to H815 or something that flashes without error
First, if it's H815, you're to flash an H815 kdz with LG up

Put into download mode and refurbish the kdz accordingly.

Hi,
I tried to upgrade my LG G4 H815P with this thread:
https://forum.xda-developers.com/g4/development/h815-nougat-stock-locked-bootloader-t3709119
The process with LGUP was ok (upgrade mode), but after the first reboot the phone stucks on LG logo, so I tried to use refurbish mode but the process throws a error 0x2000.
I tried a lot of solutions but the problem continues.
Maybe you know a tot file with android 6 to restore my phone with LGUP?

Seems like the restore only works with H81520p_00_0314.kdz
Solved!
