I believe the issue was a lack of space disk (FWUL doesn't let me access the 64gb of the sd I installed it on....)
is it normal that I don't have an extract + flash button at the bottom right ?

the usb disk / stick where you flashed FWUL on cannot be used by anything else then FWUL boot. at least if using the forgetful option and persistent is deprecated already (as v4.0 will include an installer).
as you do not share the log as suggested I cannot say much but at least you shared a screen (pls remove it though bc it contains your imei).
due to the fact that you are on laf protocol 100001 you can in theory use SALT to flash but as you found out already this is not enabled by default as it is HIGH risk and HIGH experimental.
if you want to still proceed u need to start SALT with "--experimental" but again - even when I have used it a lot it might brick a device for others.
It's an old G4 that was going to the trash anyway so I'm willing to take risks. I've tried my luck in all the windows software and nothing. I really want to try and flash a fresh kdz
So in order to start SALT with --experimental I have to run it from command ? Sorry, not used to linux...
So in order to start SALT with --experimental I have to run it from command ? Sorry, not used to linux...
open a terminal (square black icon in the panel)
type:
sudo ./programs/SALT/salt --experimentalbut beware even when there is a "KDZ flash" button this is not yet fully implemented. you have to use "flash folder" instead. the reason is that when choosing kdz flashing with LGup not all partitions get flashed. e.g.
do not flash:
- misc
- encrypt
- devinfo
there might be more but I hadnt had the time to look into that.
basically - when unlocked - the only thing needed to upgrade a device's firmware is
- the bootloader stack
- system
- boot
- modem
when your device is locked then you need to flash laf as well but this might prevent using SALT flashing once rebooted.
so my recommendation is to unlock the device first (if not done already), then take a SALT backup, then flash just the bl stack + system + boot + modem as mentioned.
So I tried... and got an error as well from SALT. I attach the log if someone can have a look maybe ?

I just want to thank you for your SALT tool. It helped me a lot.
My LG G2 D802 was really in a strange stage. I tried to flash to stock firmware with various tools runing on Windows but nothing worked.
With this experimental mode of salt I was able to flash my LG G2 to stock firmware and then move on to LineageOS 18.1 and everything is working nice and smooth.
I almost gave up on my phone but your tool saved my good old phone from ending up at the recycling depot!

It seems to work on LG H221AR (LG Joy/Kite), right now flashing an extracted KDZ for it. Slow, but works.

About
steadfasterX's All-in-one LG Tool (SALT)
SALT is able to communicate with your device while in download mode and provides these features:
Detects your:
- ARB
- device model
- firmware version (short)
- firmware version (full)
- country of firmware
- Secure device state
- Battery Level
Is able to:
- working completely without any LG dll (no more issues with replacing LGUP_xxxx.dll anymore!)
- backup your device (predefined modes: full & basic and since v3.20 even a custom mode)
- extract KDZ files
- display your partitions (including what each partition is like bootloader etc!)
- open a shell on the device*
- ERASE (HOLY SH*** this is DANGEROUS!) one or multiple partitions
- verify a taken backup (read all about this here)
- self-update
In development (already working on LP firmware! NOT on MM or N! read the Note):
- Flashing a folder (e.g. from a previous backup)
- Flashing a KDZ
Reason:
Requirements
mAid (fka as FWUL) (recommended)
No requirements as SALT and everything needed is included there!
Highly recommended: booting mAid from USB stick to avoid any connection issues.
Ensure you use the latest mAid release and start SALT by opening the LG folder on the desktop.
Now just click the update button once SALT is started to ensure you have the latest and greatest SALT version!
Linux:
I recommend mAid (fka FWUL) in general but SALT is made to be run on any Linux (if you can set it up).
Requirements to install before beginning:
yad, git, python3, python3-pyusb, python3-crypto, python-zstandard (python3), python-pip (python3) and pkexec/policykit
(instead of pkexec/polkit gksudo will work too but this has been removed from many distributions)
Examples:
- On Arch: sudo pacman -Sy polkit git xterm python-pyusb python-crypto python-pip
and trizen -Sy yad python-zstandard (hint: you may need to install trizen first) - and you need to manually do this until it has been fixed upstream: workaround
and sudo pip3 install cryptography - on Manjaro: sudo pacman -Sy polkit yad git xterm python-pyusb python-crypto trizen python-pip python-zstandard
and you need to manually do this until it has been fixed upstream: workaround
and sudo pip3 install cryptography - on *buntu, Debian, Mint and on all derivates of those: sudo apt install policykit-1 yad git xterm python3 python3-usb python3-crypto python3-pip
and sudo pip3 install zstandard and sudo pip3 install cryptography
- On Arch: sudo pacman -Sy polkit git xterm python-pyusb python-crypto python-pip
this is all implemented there out of the box..
Windows:
Windows users should use SALT in mAid which is highly recommended for many operations with Android devices. Also read & follow the above topic "mAid (fka FWUL) (recommended)".
Installation (not needed on mAid! Just open the LG folder and start SALT)
- open a terminal
- type:
git clone https://github.com/steadfasterX/SALT.git
cd SALT
bash install-desktop.sh - read the output and if required copy the SALT.desktop file manually to your Desktop.
- double click the SALT icon or while in a terminal start SALT with: sudo ~/SALT/salt
- When starting SALT the first time you will be prompted to install necessary backend tools.
Choose YES to install them!
Note:
Even when the downloads tab in this project will contain releases the most up-to-date code can be fetched via the above way only.
Nevertheless you can download the tar file from the Downloads tab but ensure that you're using the latest code by starting an update (Update button in SALT) afterwards.
Usage
Start the device in download mode and connect it to the PC.
Start SALT.
Usually the download mode should be fully ready in 20 - 60 seconds after you see the cycling arrow screen.
But some devices needs up to >= 90 seconds until SALT can detect your device.
If you still get trouble connecting boot the device in download mode and let it connected that way while rebooting mAid (fka FWUL) or your personal Linux.
Known Issues
A current list of all known issues can be found at the bugtracker
Support / IRC Channel / TG Group
IRC means Internet Relay Chat and you will get best support there only.
Personally I'm only online there from Mondays to Fridays only but there are maybe others (maybe YOU too) who can help as well.
Choose how to get in:
- mAid (fka FWUL): just click the IRC hexchat icon on the desktop
- PC (HexChat and Pidgin are only 2 of them! This list is not complete!)
- Android (Yaaic, AndChat, HoloIRC, AndroIRC are only a few of them! This list is not complete!)
- Web (KiwiIRC-Web,Freenode-Webchat])
- When you have to choose a channel it is: #carbonfusion-user
- When you be asked for a server network choose: freenode
- It wouldn't hurt to read this as well when you are new to IRC: beginners guide (for a quick one read just: "Etiquette")
Simplified said: be polite, don't ask to ask, be patient(!), respect the timezones, help others.
Like mAid (fka FWUL) SALT has now a Telegram Group which is bridged with my above IRC channel as well.
Many ppl are feeling more comfortable with TG theses days and as I now have a bridge between I am ok with it...
Feel free to join
LGLAF+SALT Users TG Group
Credits (without them no SALT)

Version Information
Status: Stable
Current Stable Version: 3.22
Stable Release Date: 2020-03-09
Created 2017-12-11
Last Updated 2020-08-2633FAQ - Frequently Asked Questions
- 1) How can I get into the download mode?
Boot your phone into download mode --> the following guide is 100% working and bulletproof:- take out battery and unplug USB cable
- plugin USB cable to your PC (while battery ist still out)
- wait until you see the missing battery icon (question mark within a battery symbol)
- press Volume up and while keeping it pressed put battery in (take care that you do not press the power button)
- keep pressing Volume up until you see "Download mode"
If that does not work for you try it this way instead:
Your phones screen should look similar to this afterwards:

- 2) Does SALT work on LOCKED devices ?
Oh what a great question YES it DOES.
But keep in mind.. even when you can flash/erase partitions with SALT this still requires either valid/untouched pure LG files or an unlocked device.
- 3) Can I unlock my LG G4 device with SALT?
Holy moly ---NO!YES! ( https://bit.do/unlockg4 for the guide)
- 4) What is the meaning of ARB?
Anti-Roll-Back a stupid mechanism to brick your device. Read on here
- 5) Do I need a specific ARB version to work with SALT?
You can start and use SALT with any ARB version. Later when flashing is fully implemented you will be warned when your ARB is lower then then one you want to flash.
- 6) Which firmware versions does SALT support?
Any of lollipop, marshmallow and nougat
- 7) Which devices does SALT support?
In theory ANY LG device supported by the lglaf backend.
Confirmed devices are:
- G2
- G3
- G4 (H810, H811, H812, H815, H818, H819, VS986, LS991, F500)
- G5: unknown may only work with modifications like mentioned in the Release Notes for v3.20
- G6 (H871) only with modifications: see Release Notes for v3.20. Please help in making this fully working! OP -> topic "Support"
- V10 (H900)
- V20 (H910) only with modifications: see Release Notes for v3.20. Please help in making this fully working! OP -> topic "Support" OP -> topic "Support"
- yours -> report your device by uploading the debug log from the advanced menu and share the bpaste link!
- again: in theory any LG device will work with SALT . All newer devices (G5 and later) will just need the mentioned modification: see Release Notes for v3.20. Please help in making this fully working! OP -> topic "Support" OP -> topic "Support"
.. this will change in one of the next versions as I will implement an automatic detection , of course!
- 8) SALT is prompting me after a backup for verification. I have many Warnings|Errors what does that all mean?
Read on here about he verification feature in SALT: MD5 verification
- 9) I have installed SALT already. Is it possible to just update it?
Of course thats one of the awesome features in SALT.
Since v3.7 SALT will check for a new version on startup automatically and prompt you to update if necessary.
If it ever fails just click the update button at the bottom.
- 10) I have installed SALT already. Is it possible to switch between STABLE and TESTING channels?
Note: TESTING may have issues, brick your device, let your phone or PC explode. so use it with care.
So if you wanna still switch the channels click the update button at the bottom first.
If you want to be on/switch to the STABLE channel choose:
Click update and restart SALT afterwards.Code:SALT branch => [B]master[/B] kdztools branch => [B]master[/B] lglaf branch => [B]master[/B]
If you want to be on/switch to the TESTING channel choose:
Click update and restart SALT afterwards.Code:SALT branch => [B]develop[/B] kdztools branch => [B]develop[/B] lglaf branch => [B]develop[/B]
- 11) I have a partition file with the extension: [ bin | image | img | mbn ]. How can I convert this?
The extension is not important. The way how you extract files - is. That's why I say all the time use SALT.
On Windows the file extension matters a lot which is not the case for Linux/Android.
So if you see a guide mentioning to use a "bin" file and you have the file but with an extension of "image" (or vice-versa) it does not matters.
There is no need to convert anything as they all are just raw image files.
- 12) I want to backup but SALT says I have too less space for that! How can I get more disk space in FWUL (or my VM)?
Read FAQ #5 in the FWUL thread (yes even when you are using Windows and do not run FWUL but any other Linux + SALT) and setup a shared folder with enough disk space as described.
Point to that new shared folder (ensure you do not use spaces in the foldername and that you have created a new folder in the start of the shared folder) when asked for a backup location in SALT.
- 13) I do *NOT* use FWUL because I have my own Linux running and you told me to install tmate. How?
Current instructions can be found here: https://tmate.io/
Ensure you create a SSH key as that is needed to start tmate later:
Code:ssh-keygen -b 4096 -f ~/.ssh/tmate -N '' (note: the characters '' are 2 single quotes)
Install tmate on Arch Linux / Arch variants like Manjaro, ..:
Code:trizen -Sy tmate or: yaourt -Sy tmate (yaourt is [U]DEPRECATED[/U]!)
Install tmate on Ubuntu / Ubuntu Variants like Kubuntu, Linux Mint, ... :
Code:sudo apt-get install software-properties-common sudo add-apt-repository ppa:tmate.io/archive sudo apt-get update sudo apt-get install tmate
- 14)Is there a Windows version of SALT available or planned?
No. NEVER. Just use FWUL which has SALT already included and everything setup to manage your Android device.
If you have issues in running FWUL report them in the FWUL thread.
- 15)What is GPT compability (LG G4 only)?
I saw people often confused about that option and here is what it is and does:
1) This is only valid for the LG G4 models. If you have another one ignore it.
2) If you have a LG G4 and not UsU'd (so an official unlockable model) - just ignore it.
3) If you have a LG G4 and UsU'd your device (or planning to do so) this option is for you.
Background:
- 16) Is it possible to extract TOT files with SALT?
No but you can use this windows tool to extract TOTs: https://forum.xda-developers.com/showthread.php?t=2600575
- 17) I want to backup/extract my user data (internal storage) with SALT and my device is encrypted. Is that possible and can SALT unencrypt that data?
SALT is doing 1:1 copies of your partitions which is really 100% identical to what is on your phone. If your data is encrypted SALT will backup that in the current state which means encrypted because within the download mode your userdata partition does not get mounted. So what does that mean? Yes you can backup your userdata but .. you can NOT mount it afterwards as it is just encrypted data. afaik there are no tools available to unencrypt but I may be wrong (let me know if you are aware of any).
Does it makes sense to backup encrypted data? Depends on what you want to get. If you want to have a really full 1:1 copy of the current phone it might be useful if you are able to restore that data (e.g. via TWRP). Keep in mind though that encryption usually needs more partitions to be restored (e.g. persist or others) which contain information/keys,... as well.
TL;DR
You can but it is usually not very useful.
- 1000a) I have an issue not listed here - what should I do?
1000b) Is there a SALT logfile and how can I share it?
Advanced Menu -> SALT Debug log -> Upload button -> right click the link or open it in a browser and copy from there

Summary changelog:
ATTENTION FOR FWUL (v2.x, v3.x) users:
Upgrading to this Version WILL BREAK SALT without doing a FULL system upgrade (which can take hours, downloading multiple GB, may even break on low RAM systems)
Instead it is highly recommended to use the new mAid nightlies which are in RC phase already and so reasonable stable.
- Fix (kdztools): some fixes for KDZ extractions
- Fix (SALT): UsU and ARB detection in rare cases
- Fix (SALT): no output for several lglaf based operations
- Fix (SALT): backup (custom) progress bars
- Fix (SALT): when a folder or filename contained a space SALT failed to parse and extract
- Fix (SALT): several things around ARB and ARB detection
- Fix (SALT): screwed part listing
- Fix (SALT): log upload
- New (SALT): added a pre-check after the user selected a directory: when the path exists and containing image files the user get prompted to either retry or continue.
Newer devices using UFS storage (e.g. G5, G6, ..) still need to switch to the DEVELOP/TESTING branch (see FAQ)
