[LG V20 Guides, News, & Discussion] Phoenix591:
The lineage patches should work fine. the kernel I use for TWRP is stock based (which needs either Lineage's patches or manually adjusting twrp's config to stop the overflow), until recently it was 99% stock.

[LG V20 Guides, News, & Discussion] XolYnrac:
Hi, to me it isnot a disvantage, i consider that like a advantage because meaning we can manipulate the second screen. The task is that in the GUI layer add some area in the upper place, that would give us podinility to put anything in that area more than simple shortcut.

I am speculating because i dont know android architecture.

The other task is identify how neocore handle the modem and introduce that in lineageos kernel.

Yesterday i compiled lineageos based on a installation like this thread. When i installed that i only had problem with modem, wifi worked fine

This seems legit. Maybe? If all you have to flash is a zip why isn't it done already?

---------- Post added at 03:32 PM ---------- Previous post was at 03:29 PM ----------

Following. Let us know if you get the ROM, Magisk, GAPPS (and Xposed if possible) all flashed and installed okay. We've had some of the best V20 devs working on this for the H990 for ages with seemingly no success yet. I'm a bit skeptical of it suddenly appearing out of the blue is all. No disrespect to the OP.
[LG V20 Guides, News, & Discussion] x86cpu:
From previous attempts and [MENTION=6984210]emdroidle[/MENTION] status, it is not that simple. It requires some kernel adjustments to get the modem working. This process is not able to be automated into the Lineage build environment. However that being said, there are plans for trying to make 15.1 for h990. It might require two (h990 and h990ds) versions to get working.
[LG V20 Guides, News, & Discussion] XolYnrac:

So far, it's just hanging on the boot screen / bootlooping. I wiped /data /system /cache /dalvik, then flashed the zip and rebooted.

Am I missing anything?

update: it's booting fine now, just took a while.

• Bluetooth pairing works. (call streaming garbled, music streaming working)

• Calls work

• WiFi works

• Data works

• Camera works (Update 1: with the exception of tap to focus after taking a picture. Update 2: Tap to focus works after installing GApps (strange) )

• Google Camera works (including focus. Update 2: Using cstark Google camera port)

• Magisk v16 working (root. Update 2: SafetyNet failing. Looking into it.)

• Open GApps Nano 20180423 working

• SD card (internal and external) read and write correctly

• Auto-brightness works

• Fingerprint works

• Double Tap to Wake - this has the same issue since the G2. It works, but even if the proximity sensor is covered, it wakes the screen.

• System volumes (lock sounds, dial tones etc) are too loud and doesn't seem to be affected by reducing any other volume. Seems like a mixer_paths job.

• Substratum - this is working (I only tried apps though, not system theming yet)
[LG V20 Guides, News, & Discussion] XolYnrac:
Only wait. If at first momento doesnt crash it meaning that módem step was passed. Only wait. Be patient
[LG V20 Guides, News, & Discussion] Redline:
Yeah I've known about the plans for 15.1. I keep checking the git repos to see if there's any progress made. Maybe if possible you could look into how this guy did it (since the modem seems to be fully functional in these builds) and integrate that into your own work with LOS for the H990/DS? With credit to the OP of course. From what was said in the above post, it seems there might be a 'modem step'. The .zip seems to be laid out weirdly too O.o

[LG V20 Guides, News, & Discussion] Redline:
Okay, so since this seems to be functional, I'm gonna give it a go. Just a couple Q's:

1. Will this work on H990DS (if anyone at all knows)

2. What do I need to backup in TWRP if I want to restore to stock?

3. Is it possible to know how you got this working/share your knowledge with [MENTION=6984210]emdroidle[/MENTION] and [MENTION=2881807]x86cpu[/MENTION] in the hopes of getting a solid port done? Even if the modem changes can't be automated by the LOS builder, I for one would be happy to manually flash a modem zip when installing/updating the ROM from TWRP if it means having a functioning LOS version.

4. What is the process to keep this up to date? Will you be fixing changes and doing updates and building yourself?

5. Do you plan to try to get a version of LOS v15 working like you have v14?

6. [MENTION=8633666]joaovictorsouza[/MENTION] is there anything we should do to get it working on H990DS?
[LG V20 Guides, News, & Discussion] XolYnrac:
I did not make some special changes, I think the fix is already on lineageos tree. Here you go to picture with my changes(the picture was taken early from my laptop). The configuration are mine, but the extra c code was taken from https://github.com/ehem/android_kernel_lge_msm8996/commit/7c3c38c9f2a186f93c083f592b9f67f5f6797864, but looking that seem only is printing

Another thing, previous days i was uncompress some files from stock because "brunch" was ask me, i dont remember what files was but I think i have those separated, if is necesary at night i can say you.
[LG V20 Guides, News, & Discussion] joaovictorsouza:
1. If you build with H990ds configs in vendor or fix modem after install it should work except it can't register any network of sim card

2. System and boot partitions I think

3. I send a private message to [MENTION=6984210]emdroidle[/MENTION] with how we can boot in h990ds using h910 lineage 14.1 blobs

4. I'm not working with this now unfortunately. Maybe I'll be back soon.

5. [MENTION=6984210]emdroidle[/MENTION] is working with this. Sometime we will have it.

6. You will need build it. I'll test another method and share. But I can't fix network now.
[LG V20 Guides, News, & Discussion] Zenns:
This is rather interesting that you got working ? Last I hear there was modem issues which result in no network, so you did no special changes ? I would love to test this mate. Got a H990DS and waited for a LineageOS long enough.
[LG V20 Guides, News, & Discussion] XolYnrac:

[LG V20 Guides, News, & Discussion] joaovictorsouza:
I will try to work with the H990DS again next week. The modem is recognized, it finds a network but can not register on it.
[LG V20 Guides, News, & Discussion] Redline:
So the current status seems to be that it works with the H990 for some reason, including all modem functions, but not with the H990DS. If all I need to do to be able to go back to stock is restore a TWRP backup of all my partitions, I will give this a go and test it. I don't want to break anything that will cause me to be unable to restore to stock.

(accidentally lost all this text 3 times while typing, so apologies if this is short and to the point but I'm tired of re-typing)

I have finished testing this ROM on my H990DS. After a couple hours, I am defeated. [MENTION=7315469]XolYnrac[/MENTION] [MENTION=2881807]x86cpu[/MENTION] [MENTION=6984210]emdroidle[/MENTION] here are my steps I took:

1. After TWRP backup of all stock partitions except for system image, wiped system, data, cache & dalvik cache

2. Flashed ROM zip

3. Reboot system, waited 12 minutes for phone to boot into first time setup

4. Finished first time setup, skipped google account, passcode, etc.

5. Went into settings and mobile network options. Searched for network and found 3 providers in my area, attempted to connect to my SIM provider

6. Failed with error "Your SIM does not allow connections to this network"

7. Reboot recovery

8. Flashed neocore lineage kernel zip, reboot into system, same failure as above. 2nd screen is now active, acting as extension of main screen

9. Reboot recovery, flashed neocore 1.2 reworked kernel zip

10. Reboot into system ok, no change

11. Reboot into recovery, restored stock 7.0 TWRP backup ok, now I am back on stock 7.0. Only problem is on the lockscreen, the phone is not recognizing my knock code which I have tried many times. Any ideas?

There has to be something somewhere that needs changing or is being overlooked. Perhaps the change is already on emdroidle's github trees and needs to be merged into this H990 version somehow, but he has not been on XDA for nearly a month (he is pushing updates on github though...). Looks like this is the repository for the kernel he's trying to get working with Lineage ( https://github.com/ehem/android_kernel_lge_msm8996/commits/v0.2-branch-BUILD ). I can see things there about sim count, modem fixup, etc. but wouldn't have any idea how to use these changes or build it into a working kernel myself. I downloaded a complete zip of his 0.2-build branch but that doesn't look like something I should flash..

I'm hoping [MENTION=8633666]joaovictorsouza[/MENTION] builds and manages to get the modem working, because sadly it is unusable on H990DS without a working modem. The short experience I had with LOS was absolutely flawless, everything was so fast and fluid. For now, I'm stuck with stock 7.0, just like the rest of us DS owners. Wishing I had a H990 now. If x86cpu is aware of the kernel changes required to get the modem working, is he able to send them to me so I can test them with this ROM and see if it works?
[LG V20 Guides, News, & Discussion] XolYnrac:

Attempting now. I will update this post as I go.

Attempting using lineage-14.1-20180419-nightly-h910-signed.zip as you said you tried 'old method' with this zip and works ok. My device was previously on V10k-TWN KDZ stock firmware.

1. Had to modify /system/build.prop, /META-INF/com/android/metadata, and /META-INF/com/google/android/updater-script files in the ROM zip to change from H910 to H990. Otherwise flashing ROM zip would fail with wrong device error.

2. ROM zip flash now successful. Following 'old method' instructions now. Reboot into TWRP, flash DOTS kernel v1.4 zip (not wanting to use v1.5 as this is based on newer STOCK files).

3. Reboot into TWRP, push wireless firmware files ok. Reboot system.

4. Waiting for first-time boot. Update soon...

5. Update: First time boot completed in 5 minutes. First time boot to 1st setup screen and then crashed with yellow crash screen. Try reboot, 2nd time crash on green screen. Same green screen on 3rd time. Getting a bunch of errors that look like they are related to incorrect wifi files.

6. Unsure what to do here. Going to try flashing 'new method' zip and see if this will work.

7. Flashed 'new method' zip. Same as before, no signal on modem. Going to try and pushing wifi files over this version of the ROM.

8. This failed also. Am going to stop here. Restoring my stock 7.0 TWRP backup. I tried [MENTION=7315469]XolYnrac[/MENTION] . Need someone else to figure this out. Same error "Your SIM does not allow connections to this network".

Then I get onto syncing the H990 sources, but the walkthrough I am using mentions that I would need to cherrypick certain commits.

I'm not sure which ones to cherrypick.

Also, the walkthrough then mentions using a stock ROM to get more sources. I really don't know what these would be.

Basically, have everything I need but there are no solid walkthroughs that are for a particular device, they are more general, so it's difficult to work out wha more I need to sync / pull sources from.
