You need /cust if you like to use VoLTE and VoWifi

only delete VDF apps.
I'm sorry, I didn't know that. I've never had an operator that supported VoLTE or VoWiFi. In any case, you can always flash just the cust.img file extracting it from the complete ZIP if you mess up something.

Why? It worked for me.

I flashed recovery/ twrp with fastboot. Then i startet into twrp and flashed the img/rom. Without reboot i flashed supersu. And everytime i flashed supersu with twrp, the flashing process interrupted. And when i start to reboot into system the phone hangs on startscreen for minutes ....."LG lifes good ........powered by android".

Now i flashed supersu with sideload & adb. Phone is hanging at same screen fpr now 10 minutes....

I'm running Fulmics 5.5 (Nougat) with mk2000 kernel and LSpeed, and the phone runs better than ever. Is there a really good incentive to flash Oreo beyond the latest security patch ?

If the new features (picture in picture, revamped systemui, etc) don't tickle your pickle then happily stay on N. Some users reported better battery life in the Q&A section, but you know how these things are.

I suggest you have a look in the relative thread in the Q&A / Guides section.

If you followed the start post here, you should already have Oreo and Magisk.
Then just flash with twrp the latest MK2000 kernel (H850_v1.0-BETA5-mk2000.zip):
Oreo Beta Folder
Flashlight will then work again.

My mistake was not to flash the kdz file with LG UP. I just flashed the zip file before. Now it runs. Thx

    Stock Firmware H850 V30a "Oreo" OPEN EU ROM

    KDZ-File: H85030a_00_OPEN_EU_OP_0910.kdz (MD5)
    Flashable ZIP Complete: LG-H85030a-Flashable.COMPLETE.zip (MD5)
    Flashable ZIP Boot: LG-H85030a-Flashable.Boot.zip (MD5)
    Flashable ZIP Bootloader: LG-H85030a-Flashable.Bootloader.zip (MD5)
    Flashable ZIP Modem: LG-H85030a-Flashable.Modem.zip (MD5)

    Android 8.0.0
    Patch level: 1 September 2018
    Baseband: MPSS.TH.2.0.c1.4-00070-M8996FAAAANAZM-1.163432.2a.168009.1
    Kernel: 3.18.71
    Build: OPR1.170623.032
    Software version: V30a-EUR-XX

    Changes:
    - Android Oreo

    Instructions:
    Upgrade from Android 7 and root using TWRP and Magisk
    1. Do backups! Expect to lose your apps and settings!
    2. Get the required imgages:
      • H85030a_00_OPEN_EU_OP_0910.kdz from above --> store it on your HDD.
      • twrp-3.2.3-2-h850.img --> HDD
      • Magisk 17.1 ZIP file. Copy it to your G5's SD card.
      • the LG-H85030a-Flashable.COMPLETE.zip from above --> SD-Card.
      • Optional: You can additionally download the MD5 file which is being used by TWRP to verify the ZIP file (simply place it in the same folder like the ZIP).
    3. As a safety measure, I'd clean upgrade with the stock KDZ first using LG UP. This will replace also recovery to stock. If successful, you can continue.
    4. Unlock the bootloader (if not already unlocked) as described here with the official bootloader unlock and flash TWRP. TWRP 3.2.3-2 worked for me. Boot into TWRP as described.
    5. Optional: Do a backup in TWRP.
    6. Format Data: "Wipe" > "Format Data" > type "yes". Wipe slider wipe is not enough!
    7. Go back until you see the TWRP main screen. Then Reboot into Recovery. Don't start into System!
    8. Flash / Install the LG-H85030a-Flashable.COMPLETE.zip and Magisk-v17.1.zip without reboot inbetween.
    9. Reboot to System
    10. enjoy!


    To build the ZIPs I used parts of autoprime's previous files. Thx again!

    Disclaimer: This is not an official post by LG to update the firmware! Don't blame me if you destroy your phone. If you use these files and instructions you do it at your own risk!

    V30f flashable zip

    I made a flashable zip from the v30f kdz. It is the full ROM so it will work for a dirt flash from v30a as well as for a clean install.
    I've uploaded it to Mega:
    Download LG-H85030f-Flashable.COMPLETE.zip
    SHA1 checksum: C8D80CA80282AADA16A5CF4E54EA76F1B9185046

    Thanks to DavidFlint for the base zip file and thanks to asialove2013 for posting the kdz file here .

    30A boot.img "modded"

    - disabled forcencrypt (format data via twrp if you have enabled encryption)
    - disabled drm-verity
    - insecure boot.img
    - (selinux for deodex)

    Flash via twrp (install image)
    root via supersu

    I want to leave some Feedback, maybe it will help others:

    I have a H850 (Germany) with LOS Oreo installed.
    1. I booted into recovery and manually wiped everything except external SD.
    2. Reboot to Recovery.
    3. Flash complete zip and Magisk 17.2
    4. Reboot to system (took 1-2 minutes).

    I did not need to flash the KDZ first and I did not end up with any bloatware/unwanted apps. TWRP was still there after I completed the flashing procedure.

    I followed this as well.Flashed the latest TWRP.
    Booted to Recovery and wiped everything except SD.
    Reboot to Recovery and flashed comeplete zip and Magisk AND MK2000 kernel.
    Reboot to system and everything worked.
    Flash works, torch works and fingerprints work.
    No bloat apps and all is working great!
    Thank you!
    P.S. I came from Fulmics 5.5 and did not flash KDZ

    Yes magisk is the reason. In other thrad they say "change kernel to MK2000 is the solution".
