The presented files for root in the official firmware f800 * Android 9. Based on the official sources PIE of the LG with minimal changes (fixed static boot ).
Only for F800 * phones with unlocked bootloader.
Small manual
LGup firmware in "partition dl" mode KDZ android 9, remove daws aboot, abootbak, laf (
laf must be left from android 7-8).
In Fastboot mode, run boot-twrp.bat (the kernel and TWRP will be flashed).

Go to TWRP: Cleaning - Selective cleaning - select the "ENCRYPTION" swipe ... be sure to before each DATA format .. (This is a feature of this TWRP only), data format, wipe cache and dalvik cache. Reboot TWRP.
Installing Magisk first, then Lg_rctd_disabler as desired. If you need to disable encryption, flash Disable_Dm-Verity_ForceEncrypt_03.04.2020, otherwise you do not need to flash this file. TWRP supports encryption MTP+ADB+OTG .
For F800S only: Before the first system boot, System / Product / Priv-app remove "Findlostphone".
Next, reboot into the OS.

TWRP 3.4.0 : Enable MTP before connecting to PC! , Use the data backup with the previously disabled password lock, pin code, ....
Config TWRP android 9 (us996.zip)

MTP, second screen...OS no problem F800S version (as in android 7-8).

The "fixed static boot" and "us996.zip" files are the source for developers who wish to build their own kernel or TWRP.
Presented as is. any borrowing, modifications and changes are welcome :)

LGup for KDZ firmware, for example (F800L30e_00_1022.kdz) for F800L.
BAT file for Fastboot mode of the phone.
Boot-twrp.bat + TWRP.img + boot1.img must be put in the Fastboot folder before starting.

It's very simple if you have experience unlocking the bootloader.

I already have the F800L30e installed
And I have the KDZ file
Where do I get the BAT file from?
And I get waiting for device
When I try to play the file
Yes i have drivers
yes i checked it works
This is just for short answers for you
You mean the BAT file that is in the first message Or another file
Because the same file in the first post I tried several times
And it does not work for me
In which folder to run the file In the fastboot folder
Or from the main folder

In the "download mode" you will not succeed. You need to put the phone in "fastboot mode" to write TWRP + boot.

If you do not have "fastboot mode" then the bootloader is blocked. If I understood you correctly, then this is exactly so.
^^^Only for F800 * phones with unlocked bootloader^^^

2 This Write download mode That's what I put it on
3 How do I get to "fastboot mode "
Volume down + cable not working
Yes the cable is connected to the computer
Yes the device is turned off

You can ignore it!
The dirtysanta method does not bypass the bootloader.
The bootloader is overwritten by the engineering unlocked from us996 (aboot.img, abootbackup.img).
With the rule ((LGup firmware in "partition dl" mode KDZ, remove daws aboot, abootbak)), there will never be problems when downgrading or upgrading the android version (repeating the "dirtysanta method" will not be needed).

In short, "permanent unlock" with an unlocked bootloader from us996.

The F800 dialer has a built-in call recording and records well. Google Voice is not needed for this. WhatsApp, like many other messengers, does not have a built-in recording, attempts to record by third-party applications often lead to poor quality (the compression quality plays a big role as the connection quality). Try every possible application, even outdated ones, and you might find the right one.

I can be wrong somewhere, I don’t use call recording.

Hi im on f800l with pie have you a kernel for software Version 30h? Thanks
The official kernel sources for Android 9 (LGF800L_LGF800K_LGF800S_Android_Pie_v20a) were released in a single version, without updates. PIE 30h, 30e must be compatible with the kernel. This kernel was posted by me on another resource more than a year ago, here recently. So far no one has spoken about the incompatibility of the kernel with the "30h" firmware. Otherwise it would have been indicated.
