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...

open a terminal (square black icon in the panel)
type:
sudo ./programs/SALT/salt --experimental

but 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!

    About

    salt_pre.png


    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
    IMPORTANT NOTE: Do not use the underlying code backend (lglaf /partitions.py) to RESTORE image files (yet)!
    Reason:
    LG has changed the mechanism in MM and later for writing to a partition! It seems that the reason is that each write must be authenticated differently or at least another one for the fsync.




    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
    you may need to setup your udev rules as well: android-udev-rules thats another reason why I recommend mAid ;) 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)

    FAQ - 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:
      1. take out battery and unplug USB cable
      2. plugin USB cable to your PC (while battery ist still out)
      3. wait until you see the missing battery icon (question mark within a battery symbol)
      4. press Volume up and while keeping it pressed put battery in (take care that you do not press the power button)
      5. keep pressing Volume up until you see "Download mode"

      If that does not work for you try it this way instead:
      1. unplug USB cable
      2. power down device or pull out battery
      3. put battery back
      4. press Volume up and while keeping it pressed plugin USB cable to your PC (take care that you do not press the power button)
      5. keep pressing Volume up until you see "Download mode"
      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:
      Code:
      SALT branch => [B]master[/B]
      kdztools branch => [B]master[/B]
      lglaf branch => [B]master[/B]
      Click update and restart SALT afterwards.

      If you want to be on/switch to the TESTING channel choose:
      Code:
      SALT branch => [B]develop[/B]
      kdztools branch => [B]develop[/B]
      lglaf branch => [B]develop[/B]
      Click update and restart SALT afterwards.

    • 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:
      SALT checks the partition table (GPT) to find out what ROM model is compatible with an UsU'd device. The reason is quite easy: all G4 models have the same hardware (except the h818 but thats another story). Due to the incredible amount of country specific models not many ROMs exist for every model so I checked what's needed to bring a ROM meant for another model to an UsU'd device. I recognized quickly that the partition table is different on several models and even on a same model with another firmware (e.g. between LP and MM it changed for some models). The only thing we need on custom ROMs for the G4 is a correct sized system partition as that one differs for some. Another thing needed on some (mostly US models) is a carrier partition instead of a cust one. Basically that's all SALT checks at the end as if a ROM expects to mount the carrier partition it must be there.
      TL;DR
      The GPT compatibility shows what ROM you can install on an UsU'd device - if there is none for your specific model.

    • 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?

    Fix/New (lglaf): Fixes & Enhancements of the USB communication backend which SALT uses under the hood
    Fix/New (kdztools): Fixes & Enhancements of the KDZ extraction backend which SALT uses under the hood

    v3.22
    Released: 2020-03-09
    Full changelog (SALT): at github (this version compared with the previous release)
    Full changelog (lglaf): at github
    Full changelog (kdztools): at github
    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.
    HINT:
    Newer devices using UFS storage (e.g. G5, G6, ..) still need to switch to the DEVELOP/TESTING branch (see FAQ)


    Older releases

    v3.21
    Released: 2018-12-21
    Full changelog (SALT): at github (this version compared with the previous release)
    Full changelog (lglaf): at github (this version compared with the previous release)
    Full changelog (kdztools): at github (this version compared with the previous release)
    Important Note:
    From this release on the system requirement have changed!
    You need to ensure you install the python module "zstandard" - read the OP for how or when using FWUL use the latest FWUL nightly which comes with everything pre-installed.
    Summary changelog:
    • New (kdztools): KDZ extractions have been EXTREMELY enhanced. Means we can now even extract newer KDZ files up to the latest LG flagship (e.g. G7/V30).
      This has been fully achieved by runningnak3d ! it's always a pleasure to work with him ;)
    • Fix (kdztools): extraction failed when a KDZ had unallocated space (e.g. some H811 ones but also others)
    • Fix (SALT): python version for KDZ/DZ extraction
    • Fix (SALT): Browsing the mounted directory after using the Image mounter (advanced menu) will now use full permissions by default
    • New (SALT): mounting an image (advanced menu): previously when a user hasn't unmounted an image file he had to unmount it manually (terminal). now SALT offers a dialog to do so for the user instead.
    • New (SALT): from now on SALT can detect when a user tries to mount an image file from a vbox shared folder and denies mounting it
    • Fix (lglaf): Do not use "G4" as detected model (as there is no safe way to identify a model via the usb info)
    • Hint from a previous release: preparation for UFS devices (all newer LG models). Hint: you can use SALT now on newer devices but this requires a manual change in lglaf atm:
      Code:
      cd ~/programs/lglafng
      git checkout develop
      The above is NOT needed on non-UFS devices (like the G2,G3,G4, ...). If you are unsure open the advanced menu in SALT and check if the partition listing is working - if it is empty try the above otherwise you don't need to.
      The above handling and UFS detection will be done automatically in a future release of SALT!

    v3.20
    Released: 2018-11-30
    Full changelog (SALT): at github (this version compared with the previous release)
    Full changelog (lglaf): nothing has changed
    Summary changelog:
    • Fix (SALT): when the size of a backup cannot be calculated SALT continues with the free disk space check nevertheless
    • Fix (SALT): "direct flashing" message optimized
    • Fix (SALT): permissions on logfiles and all 3rd party paths
    • Fix (SALT): User detection was wrong (pkexec) and so the resulting program paths as well
      ATTENTION:
      You may get prompted to re-download lglaf, sdat2img and kdztools due to the corrected paths. Just do so and it will be fixed next time you start SALT.
    • New (SALT): Introducing the CUSTOM backup mode! Now you can not just choose from the predefined BASIC and FULL mode but also can choose CUSTOM. This CUSTOM mode allows to choose from your existing partitions. Plus: while backing up a beautiful multi-progress bar is showing the progress.
    • New (SALT): preparation for UFS devices (all newer LG models). Hint: you can use SALT now on newer devices but this requires a manual change in lglaf atm:
      Code:
      cd ~/programs/lglafng
      git checkout ufs-test
      The above is NOT needed on non-UFS devices (like the G2,G3,G4, ...). If you are unsure open the advanced menu in SALT and check if the partition listing is working - if it is empty try the above otherwise you don't need to.
      The above handling and UFS detection will be done automatically in a future release of SALT!
