He will also need to make sure he is on Nougat firmware before installing LOS 17.1. If on Oreo, that means either installing someone else's backup image of the modems from his specific phone type, or using LGUP to flash a stock image for his phone, rooting it, flashing TWRP, and then doing the wipe\LOS install.

I´ve tried this but I got the TWRP Error 7. So I followed the steps written here to fix this error (in short: Unzip the lineageos.zip, delete the first line starting with ‘assert’ to the next semi-colon from META-INF/com/google/android/updater-script and zip it again.).

Then I tried to install it via adb sideload which failed, so restored my full nandroid Backup via TWRP. Then I tried to install it from the external sd card via TWRP which failed again with the error-message:

"Could not find 'META-INF/com/google/android/update-binary' in the zip file. Error installing zip file 'external_sd/lineage-17.1-20210328-nightly-h990-signed.zip'. Despite the fact the file: "update-binary" wasn't touched at all and is exactly where it belongs.

What should I do now?

My SetUP:

Phone: LG-H990ds

I used LGUP to install the older StockROM on it in order to unlock the bootloader/root it (sucessfully).

I successfully updated to the newest Official Lineage 17.1! But after recovering the data partition from my previous unofficial install, I can't unlock my phone because apparently I'm entering an "incorrect password", which is definitely not true, I am 100% sure it is the right password and if that wasn't enough it even says so in my keepass database. I can see my old wallpaper and notifications from previously installed software, so the backup seems to be successful, but even after multiple restarts I can't unlock my phone even reflashing the backup doesn't help. Does anyone have experience with the same issue? Is there a way to enter TWRP without adb and without losing any data? Any answers would be greatly appreciated.
[LG V20 Guides, News, & Discussion] wayase8080:
I tried to flash back to unofficial and try the backup there, but once again, the password didn't work. Now flashing back to official again even with Gamma kernel, I can't use the flashlight, camera... Weird, it worked the first time around.

[LG V20 Guides, News, & Discussion] wayase8080:
I already tried that method, but there were two major problems:

1. I don't know how to get to TWRP without wiping the data on the phone (hardware buttons) or through 'adb reboot bootloader', which i cannot authorize, because on my backup I didn't have "transfer files" as the default usb protocol and without logging into the system I cannot authorize it.

2. When I was trying out different versions of Lineage to see if the problem persisted, when I was on 18.1 I tried to reboot to TWRP through adb, then wipe, flash Lineage, reboot into recovery when I was in TWRP, then restore the Data partition, reboot into recovery while in TWRP, and then reboot into recovery from TWRP again, to finally wipe the files mentioned in that guide and in this thread under /data/system, but I couldn't find any of those files. So I'm not sure if it is only a problem cause by the files being moved around in Android 11, or even from a previous version, or if the method of rebooting to recovery from TWRP itself wasn't enough to load the data.

But I didn't lose much, since I had multiple offsite backups for "important" things and so I went ahead and reapplied the settings and reinstalled previously used software yesterday evening. Still, if you have an answer for any of the aforementioned questions, I'd like to hear them. Thanks.
[LG V20 Guides, News, & Discussion] xxseva44:
when you use the hardware buttons to get into twrp, it uses the factory reset screen to send you to twrp, it doesn't actually wipe anything, also adb commands will work as long as you had enabled adb on the phone and that ur pc was a trusted device
[LG V20 Guides, News, & Discussion] wayase8080:
>when you use the hardware buttons to get into twrp it uses the factory reset screen to send you to twrp, it doesn't actually wipe anything

Ah. Thanks a lot, I did not know that. Just to be clear, we are talking about:

Power off, volume down, power, after LG logo, release power, after ~2s press it again. Where the white screen appears and you have to press "yes" twice, right?

>also adb commands will work as long as you had enabled adb on the phone and that ur pc was a trusted device

For me they don't, unless I've specified the USB protocol to "File transfer" else ADB on my PC says: "LGUS996... no permissions; see [http://developer.android.com/tools/device.html]". I had it on always ask or charging and can't change it without unlocking the device.
[LG V20 Guides, News, & Discussion] xxseva44:
Yea when you do the whole vol down + pwr button combo and hit yes twice

For the adb thing, pretty weird, i don't enable usb file transfer when doing adb stuff as it works just fine for me

It appears that USB OTG doesn't work on H910 with LineageOS 17.1, or at least the version I'm running from back in January 2021.

Flashed this last night, must say I'm impressed. I don't use headphones so I can't speak for DAC but my camera and fingerprint sensor work fine.

The only thing I miss even a little is that I can't get ambient display to do anything but it's not that hard to just double tap the screen for my notifications.

I'm on a h910 and using gamma, and while this is still early days at this rate I'm hoping to have less crashes than los16. It has a habit of freezing bad enough that I'd have to take the case off and pull the battery.

Anyway thanks for the ROM and have a nice day.

Ah that's the issue then, Los 17 won't help you there, you might want to give gamma kernel and thermal Config.Xml a try to help you with that.

I was running gamma on Los 16 with the thermal xml, it helped some but still had a tendency to freeze. This seems so much faster on opening apps and the UI, probably my imagination but I'll give it a few days and see.

I've bought mine July 2017 and never had those issues but I'm aware that a lot of users report this. Your problem will most likely be solved by changing your cpu paste.

update since i have a second vs995 now, kernel panic only happens when booting with a sim card(note on 4/10 it is an auto power off and reboot to recovery--not a kernel panic). clean install from nougat, fingerprints other sensors work, APN sticks now

so to reiterate for all Verizon users as of 04/10 nightly

can't boot without workaround if you have a sim card inserted

Got the above mentioned camera working with gamma and permissive workaround also the JOKER_dev1 camera from the app forum works

[LG V20 Guides, News, & Discussion] sexmaschine:
Hi guys

I am a proud owner of a v20 h918.

As i saw that LOS 17.1 for the V20 is Official, I tried it out right away.

Here is my research:

On my h918 beforehand was installed a rooted and modded stock 20h.

I flashed x86cpu's prereqs then clean installed LOS 17.1.

And as described in the forum all sensors were out of order and the camera was broken.

As described here in the forum, it helps to change the selinux mode from enforcing to permissive.

In my case i patched the Kernel to selinux-permissive, inserting it as kernel parameter.

After data wipe and a few restarts, all sensors and camera worked.

Curiously, the sensors now also work with unpatched kernel after a complete clean reinstallation of LOS 17.1 !!

I wiped everything and after a new installation everything worked perfect.

This means that the selinux mode permissive enables/allows LOS 17.1 to change a prereq-partition.

And now it comes: After LOS 17.1 worked perfectly, i reinstalled stock v20h on my h918 and who wonders, all sensors without function.

When I changed the selinux mode to permissive in stock 20h, the sensors worked here too.

But stock 20h is not able to change the prereq-partition, so it only works in permissive mode !!!!

So be careful - Stock-Rom can not undo the changes from LOS 17.1 !!!

Fortunately, I made a backup of all v20 partitions originally.

So I compared which partition was changed and found out, that after restoring the "sns" partition the sensors in stock 20h work again in selinux-enforcing mode.

Conclusion in order to get LOS 17.1 working properly, it has to change the "sns" partition, but that cannot be undone by a stock-rom !!!!

So please create a backup beforehand !!!

Otherwise a big compliment and respect to all involved and developers who made LOS 17.1 Official for our V20 possible !!

here's my .zip for patching kernel to permissive

Hi All,

Thought I'd post my results. I stayed away from Unofficial 17.1 and stuck with 16. I have a spare phone so I've had a go at flashing Official 17.1.

Discovered that Gamma doesn't play well - caused the phone to lock up and needed a battery pull to recover.

Have ended up going to Official 17.1 and leaving the stock kernel - working very well

H990DS

Downgraded to 10c

Flashed 17.1

Flashed Gapps

Flashed Magic

Everything working as far as I can tell. FP sensor working, stock camera working, flashlight working.

Running Nova

The whole phone is super smooth, quick and very responsive.

Gotta love my V20
