The camera seems to not be recording video, even on 720p mode. It records but the video files are corrupted. Just caught big foot on video but I still have no evidence because of course my Android 10 Q Korean rom got in the way. How convenient for bigfoot right?

Code:
mediainfo 20210226_183931.mp4
General
Complete name                            : 20210226_183931.mp4
Format                                   : MPEG-4
Format profile                           : Base Media / Version 2
Codec ID                                 : mp42 (isom/mp42)
File size                                : 44.9 MiB
IsTruncated                              : Yes

That's the mediainfo for the file and that's all it shows. It's there any way to recover a working video from it?

I can confirm the same issue, but I didn't even realize until you pointed it out. So it almost doesn't feel like too much of a loss.

If you want to record video using a camera app and not a social media app like all the cool kids do nowadays, I suggest the Google Camera app. As I can confirm this still works.

The camera app is capped at 1080p, so we loose that sweet sweet storage hogging 4k 60fps. But again, I guess I never really knew how much I never missed it until I noticed it wasn't there.

Btw, I ended up settling on the Simple Camera. It keeps 4k resolution although quality is not the same as the stock camera app. Something is different about the end result and the UI is clunky but you do get 4k.

Switching to the OPEN_KR_OP version has really helped my AT&T signal quality. In most cases, I'm getting full 5 bars wherever I'm at! For example, previously I was hitting 2-3 bars around my neighborhood, now I'm able to use hotspot and reach 40-50 Mbps.

Sorry for triple posting but by google camera you mean the GCam for the Pixel? Or this one: https://play.google.com/store/apps/details?id=com.google.android.GoogleCamera&hl=en&gl=US honestly not sure if it's the same. Can you point me to the one you got for the Korean Q? Thank you!

This is what I use for the V35

This apk works well with the LG v35 config file. As it's been my experience before all those gcam mods leave a lot to be desired in terms of quality.. I think Simple Camera produces better results but if anyone's interested in one that works well for the Korean Q that one does.

If you want to fix the corrupted files recorded using the stock camera app I can confirm this tool works: https://github.com/anthwlock/untrunc it doesn't seem able to get the audio but it does get the video. Using a video recorded with the gcam as the "ok.mp4" works but the videos recorded with the Simple Camera don't.

Everything is working right, from 8 awm to 9 ulm, and then 10 korea.
But the nt error keeps popping up every start up.

Someone mind helping me out? Im doing this with 30C but after step 16 I get stuck booting. Not bootlooping, just booting. Ive tried the v6 master.zip from the github but it gives me a "invalid file format" error. any suggestions would be appreciated.

HI,

I stuck at Step8.
I cannot copy to root filesystem..
Oh, and the buttons in Magisk disappeared...
I know I'm way late with this but don't reboot after installing TWRP from Magisk... when you rename the one folder then quickly go back to Magisk and reboot to Recovery and you should be good to go.

Another tip... you can install Magisk.apk *OR* flash it like a zip from recovery.. it works both ways. The instructions don't really make this clear. I screwed up on one of my 5 install attempts by installing an old version of Magisk from a zip file that was already on my SDCard because I didn't have the newer version of Magisk in ZIP format (I didn't know I could flash the APK file).

To keep myself from getting confused, I made a copy of the apk and then renamed it to MAGISK.ZIP and saved it in the same folder. It worked great!

    IF YOUR BOOTLOADER IS NOT ALREADY UNLOCKED, THIS GUIDE IS NOT FOR YOU.
    READ EVERYTHING AT LEAST ONCE BEFORE PROCEEDING!
    THIS GUIDE WORKED GREAT FOR AT LEAST 3 PERSONS, THIS DOESN'T MEAN IT WILL WORK ON YOUR PHONE.


    This guide exist in case the ULM Q never released :)


    This guide should do the following :
    • relocalize to your country (I'm only providing the files for canada, usa and eu)
    • Root and TWRP (useful if any custom roms get released)
    • debloating
    • volte/vowifi/vilte/viwifi
    • Very Good battery (see screenshots down below)
    • mute shutter camera
    • 4k 60fps video recording (?some people said it wasn't available on the korean Q?)
    • wifi tethering
    • and more

    WHAT'S NOT WORKING FOR ME :
    • lg smartworld : meaning no lg app update.. which can lead to the next problem
    • Drag down for search : working only if you do not update the google app

    What you need:
    • 1 to 2hrs of free time
    • Working QFIL with minimal knowledge
    • Working Fastboot on your pc (See spoilers)

      I did NOT manage to make fastboot work on my amd ryzen pc (3600)
      here's what I tried :
      - multiple fastboot drivers
      (fastboot was kinda working.. now it just never load any driver)
      - plugged in a usb 3.0 hub
      - FWUL : https://forum.xda-developers.com/an.../live-iso-adb-fastboot-driver-issues-t3526755
      (the latest version as of 2020-11-25 couldn't even boot on this pc...)
      - ubuntu
      (crashed the phone to a gray screen)
      - all my usb ports : 2, 3 and 3.1​
      What I didn't try but could work for you:
      - plugged in a usb 2.0 hub
      - linux mint?​

      Soo... what did I do? I went back to my good ol' intel pc running windows 10 :) worked like a charm.

    Also, this guide assume you had working volte/vowifi on your phone at some point...
    Because, you will need the carrier folder from the /oem/op/ folder.. should look like this : open_us, vrz_us, open_ca..
    Or you will need to retrieve it from your working firmware...

    I'll be providing :
    - Android 10 - G7 - OPEN_CA (Canadian operator folder) (What I'm using on my phone right now)
    - Android 9 - V35 - OPEN_US (ULM/GFi) (Confirmed working by @cmrntnnr)
    - Android 10 - G7 - OPEN_EU (untested) (thanks @vlad48)

    !!!!!! Before crossflashing to the korean kdz !!!!!!
    ------------------------------------------------------------------------
    Crossflashing can break stuff sometime.. it is advised to do a full backup of your phone using https://github.com/bkerler/edl
    if you're feeling lucky and do not want to do a full backup... you should still use qfil to atleast backup the following VITAL partitions : Fsg, modem, modemst1&2, ftm
    STORE THOSE FILES PRECIOUSLY
    ------------------------------------------------------------------------

    File you need to download :
    To your phone SDCARD :​
    To your pc:​

    You need to use SOLID EXPLORER, not esfile or any other since I can not guaranteed it will apply the correct permission to the files and folder.

    1. LGUP > Flash V350N30b_00_LGU_KR_OP_1015.KDZ using partition DL, select everything except FTM
    2. Let the phone boot for the first time and reach setup screen
    3. LGUP > refurbish phone using the kdz (this should fix potential nt error when booting the phone, it did for me)
    4. Let the phone boot for the first time and setup the phone quickly so you can install app. (no lock or fingerprint)
    5. Patching vbmeta to edit the operator/carrier information & patching boot for magisk/root
      • QFIL > partition manager > abl_a > read, store that file and name it : needed_abl.bin
        How to retrieve the file: WIN+R , %AppData%/Qualcomm/QFIL , enter, pick right folder, save and rename bin file​
      • QFIL > partition manager > abl_a > load > engabl.bin (for fastboot)
      • QFIL > partition manager > abl_b > load > engabl.bin (for fastboot) (Optional)
        This is useful in case you need fastboot in the future, simply boot twrp then change slot from a to b and reboot.
        To switch back from fastboot : fastboot --set-active=a​
      • reboot the phone using vol- + power
      • command :
        Code:
        fastboot --disable-verity --disable-verification flash vbmeta_a vbmeta.img
        fastboot oem edl
      • QFIL > partition manager > abl_a > load > needed_abl.bin
      • QFIL > partition manager > boot_a > load > boot_magisk.img
      • reboot by holding vol- + power
      [*]
    6. Reboot to system, Install magisk manager and solid explorer
    7. Start magisk manager and let it reboot your phone
    8. magisk > modules > install from storage > twrp-installer-v3.3.1-v35_a.zip
    9. SOLID EXPLORER > copy the carrier folder to the oem/op/ partition ('OPEN_CA' in my case)
    10. SOLID EXPLORER > edit oem/op/cust_path_mapping.cfg and replace LGU_KR with OPEN_US ('OPEN_CA' in my case)
      If you're still getting nt error at boot, you'll have to fix it in order to make the phone load open_us..
      try adding a second line like this :
      FFFFFF,84=/oem/OP/OPEN_US
      If this doesnt do it, you'll have to share your nt error in the comment.
    11. SOLID EXPLORER > Rename the folder /oem/op/LGU_KR to LGU_KRori (this will make your phone lag/glitch/freeze real quick.. proceed with the next step ASAP)
    12. Quickly go in magisk and use the reboot menu to get to twrp. (reboot to recovery)
    13. Format data
    14. Reboot to TWRP/recovery
    15. Flash Magisk-v21.1.zip, if it doesn't flash, reboot using the reboot menu to TWRP/recovery again until it works. (no red text)
    16. Flash Disable_Dm-Verity_ForceEncrypt_11.02.2020.zip
    17. Reboot to system
    18. if the vowifi toggle is not working for you
      For OPEN_CA/OPEN_US :
      SOLID EXPLORER > move debloated-priv-app-RENAME-ME to /oem/op/priv-app/
      SOLID EXPLORER > Rename the new folder to OPEN_US or OPEN_CA
      Reboot
      FOR OPEN_EU : (these steps are from the v40 community telegram, Quote from Lucky)
      magisk > modules > install from storage > voenabler-v1.8.zip
      If you transplant the KR OP with OPEN_EU, and are based in EU, this module should add the props that enables the VoLTE and VoWifi options.
      Only if this fails, do you need to tinker with the xml files.


      Optional.
    19. Adding back missing lg apps (I provide QMemo and LG Weather)
      you can either install manually the apk from debloated-app-RENAME-ME
      or
      move the folder to oem/op/app/ and rename it OPEN_CA or OPEN_US
    20. Enable LGMessage over Google message and add back LGFMRadio (you'll need to uninstall any sms app you might have installed.. like google message or fb messenger(if used for sms))
      Solid Explorer
      edit this file /oem/op/open_us/config/custom_apk_list.cfg
      change the sign on the following lines (from - to + and + to -)

      -com.lge.fmradio:/system/product/priv-app/LGFmRadio
      -com.android.mms:/system/product/priv-app/LGMessage
      -/system/app/SmartMessagingEngine
      +com.google.android.apps.messaging:/system/app/Messages

      Example
      -/system/app/SmartMessagingEngine
      to
      +/system/app/SmartMessagingEngine

      Reboot
    21. Do not forget to enable developer option and adb AND
      Plug you phone in computer, open adb shell and type su
      on the phone, grant root.
      It is useful to have a root shell in case the phone is stuck while booting (not boot looping)
      you can also just reboot to twrp and undo your modification from there.

    Thanks to everyone patient enough to answer my questions and who did provide most of the solution for this guide:
    vlad48, Lucky, azitlies, xsavi, kaneorotar and many more.. :D
