downloads don't complete.

Every time I download the complete zip file download stops. I've tried it like 4 times but download never completes.

complete has all parts , yea.
no it won't flash recovery.
no su in rom. after flashing complete, you need to flash su.
this rom is from last year. you prefer to flash stock rom 1 year old ? security patch is old here.

I don't know if with a clean install of the V20p works, but I did this:

Followed the tutorial to install and root V20g.
With LGUP upgrade to V20p (lost ROOT).
Again with adb installed the temporary TWRP on the phone and reinstalled SuperSU like for the V20g.

It worked! Rooted and working great!

Security Patch: 2017-03-01
Kernel: 3.10.84
Build Number: MRA58K
Software Version: V20p-OPT5-SI
Baseband VersionMPSS.BO.2.5.c3-00101-M8992FAAAANAZM-1.31581.1

People can try to jump the V20g flash procedure, flash the V20p and see if it works, later post it here how it was :)

Good luck to all

Hi,
I followed the instructions, but I get this loop where the phone boots, goes through "Updating apps x of 18", reboots and repeats the cycle again indefinitely...
What should I do?

Restore a backup of data partition if you have one ofcours. If not, make one and try to restore it. As last resort, wipe data dalvik and cache aka factory reset.

Here, there was still a technical problem with the installation of recovery TWRP by Fastboot - so I used the app.

I was using original nougat version. Yesterday, I have decided to try lineageos based android 16.0 from xda. I have unlocked the bootloader install TWRP & lineageos16 & gapps but I found it uncomplete. Then I return to original nougat version by installing complete.zip from androidfilehost. Now my phone works OK, but everytime I reboot, shows a bootloader unlocked message. I have tried this tag but not works for the nougat. Any info?

    These are for the H815 variant only. Files are from software version 20G (Android 6.0 Marshmallow)... more specifically from the 20G Poland carrier-free version. Included below: TWRP-flashable stock rom, boot, modem and bootloader zips. KDZ and individual images are also included.

    20G NOTES...
    Improved stability for apps.
    Phone usability and functionality has been further improved.
    Android Security Patch = 2016-07-01

    *There is NO anti-rollback qfuse used in this update*

    Requirements:
    You must have TWRP 2.8.7+ installed to use these zip files. Thanks to Dees_Troy as always for that. And, of course, you must have your bootloader unlocked for TWRP to work. Currently only H815 EU and (some) SEA variants have official unlock through LG's unlock page HERE. Please do not ask if "model x" is supported... did you unlock via LG's official unlock tool? Yes? then you can use the zip. No?.. then you should skip the zips and just flash the KDZ instead.

    If you have a locked bootloader and want to upgrade... just use LGUP and flash the KDZ. Don't risk it with FlashFire.

    Install Directions:
    These directions should be used by everyone who wants a rooted 20G system.
    Don't want root? Then it's probably easiest to just flash the stock KDZ using LGUP HERE... or just skip the SuperSu steps.

    1. Download LG-H81520G-Flashable.COMPLETE.zip listed under the download section and place it on internal or external sdcard.
    2. Also download the latest SuperSu zip (2.67+) from HERE [Thanks to Chainfire for his auto-patching boot.img version!]
    3. (re)Boot into TWRP if not there already.
    4.* Backup current partitions: boot, system, data, efs (backing up anything is optional but suggested)
    5.* Up to you if you want to wipe data (TWRP > Wipe > Swipe slider) but not needed if coming from a stock rom.
    6. Install LG-H81520G-Flashable.COMPLETE.zip (Install > select zip > swipe to confirm/flash)
    7. Install SuperSu zip (Install > select zip > swipe to confirm/flash)
    8. After zips finish flashing you can reboot! (if TWRP asks if you want to install SU, HIT NO!!!)

    Please do not mirror my files!
    Downloads:
    LG-H81520G-Flashable.COMPLETE.zip
    LG-H81520G-Flashable.Modem.zip

    Downgrade:
    To downgrade you can use TWRP to restore your backups... and then just flash the matching bootloader zip and modem zip from my previous threads... or just check the CODEFIRE DIRECTORY link for previous stock files.

    OR

    Use LGUP HERE to flash a previous KDZ version. KDZ will remove TWRP but easy enough to reinstall that.

    Unofficial Bootloader Unlock:
    Don't have official bootloader unlock? This guy claims to have a working method HERE...

    Awesome! If I'm already running Imperium 5.0 and just want the updated bootloader and modem (currently using the 20d variants), I'm guessing I can just backup and flash the modem and bootloader zips in TWRP? No need to completely return to stock/install the full zip?

    correct.. there is no need to flash full unless u want stock(or stock rooted) lg. an updated modem/bootloader may or may not agree with the system/rom you're using though... sometimes things change where the "rom-base" must be updated to work with the new modem or bootloader. but worst case you just flash the old modem/bootloader back. If I had to guess though I think it should work for ya.

    hello im on cm 13 but my camera auto focus does not work. I just need to know what I need to download from the first page and installation order so I do not mess up my phone.

    other than the current camera not focusing I do not have any other problems. If some one could just simplify which one i need and do not need and the order I would greatly appreciate it

    download LG-H81520G-Flashable.COMPLETE.zip to sdcard/download folder
    download version 2.67 of SuperSU from the link in the instructions to sdcard/download folder

    boot into TWRP (recovery)

    Use TWRP to wipe dalvick cache, as well as cache partition, and system partition and boot partition - do NOT wipe internal memory card or external memory card or recovery partition or data partition

    the immediately use install mode on TWRP to install LG-H81520G-Flashable.COMPLETE.zip

    then immediately use install mode on TWRP to install version 2.67 of SuperSU from download above

    reboot or power down phone, if TWRP asks if you want to install SuperSU or if you want to root phone, say no

    be patient, it takes a few minutes to sort everything out on first boot
