I can confirm that charging working well on H990DS. The problem i have is the bluetooth. It can't connect to a bt device, and when i turn it on, it turns off immediately (difficult to turn it on). And randomly reboots. It happens since LOS 18. Are you facing this issue too?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] stsz1954:
Hello.

I have tried to flash both the rom and recovery image on my h918. i followed the directions on the wiki until I tried to flash recovery on the device. After I typed this command, fastboot flash recovery recovery.img, I got this output:

Warning: skip copying recovery image avb footer (recovery partition size: 0, recovery image size: 26341376).

Sending 'recovery' (25724 KB) OKAY [ 0.871s]

Writing 'recovery' FAILED (remote: 'unknown command')

fastboot: error: Command failed

Can anyone mention how to get out of this situation?

Thanks for any reply.

Bluetooth works fine for me on both of my problematic LG V20 running LOS 20 & 19.1. Even when in 18.1 it still works fine. I have tested pairing between devices, send/receive files, wireless headset, etc.

I do remember I had bluetooth issue in LG V20 back when running Oreo though, forgot which ROM, but there was a patched .zip that fixed the bluetooth issue but it's specific to that ROM I was using. Were you dirty flashing LOS from Oreo based ROM?

Though I experienced a more frequent reboot on LOS 18.1; hence why I tried to upgrade to 19.1 & 20, which seems more stable. Only 1 unexpected reboot so far.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] andruyd:
out of curiority, what kind of bluetooth devices have you tried on los20?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Envinite:
Tried pairing & sending (small sized) files from & to my other V20 running LOS 19.1 and Windows 11 PC, works okay. Pairing & paly audio with bluetooth earphone also works fine. At least for my case.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dextructor:
Dirty flashing from another major lower version "it's supported" but never

encouraged (at least on my opinion/experience with various devices). So your mileage may varies, and of course bugs.

My first V20 (H990DS) had some strange behaviors that couldn't be

explained at first, like random reboots, apps/data disappearing and so on. So after first replacing the OEM with Perfine battery and issues continued, I discussed with another dev the source of my problems and decided to buy another motherboard and replaced with an H990N. Now I don't have any hardware related problems.

Now I have my daily driver (H990N) with Lineage 20 + MicroG and the

spare H990DS I test different softwares/firmwares.

On both V20's I could charge after turned off the device both Perfine

(39% to 68%)and OEM battery (25% to 70%) in about 1 hour using the dash

charger from my OP3 with his cable and Samsung Quick Charge 2.0 + USB

3.0 cable.

Our over-engineered USB port can be the source of many issues for some

users and or the culprit, but on my devices the LG software wasn't

great. Because on the H990ds10c the file transfer on USB refused to

work on any port of my USB HUB, only worked with a slower USB 2.0

direct port. With Android 8 or 9 this problem don't exist, and of

course that Lineage work's perfectly fine.

I seriously doubt that can be any log while the device it's powered

off, but as always I can be wrong.

When I had similar issues with my H990DS I checked:

0) Refurbish (or partition DL) again to the H990ds10c KDZ

1) Any type errors on terminal

2) Older adb/fastboot versions can have bugs or cause random errors.

3) Downloaded file may got corrupted. So verify it for obvious reasons.

4) Other USB cable and specially not all USB ports are equal in quality (reference 1 and another reference)
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] stsz1954:
Hello.

Originally, I used LGUP to downgrade to 91810p. I unlocked the bootloader, then used FWUL

to put TWRP on the device. Everything went fine. After rebooting, I went through the setup. I accidentally pulled the usb cable and the process stopped. I was then asked to update the system and then I agreed. Now I have 91810q on the device. Using LGUP, I tried to put 91810p back on the device. But the phone would not go into download mode, only fastboot.

When I try to go into recovery using the key combination, it goes into an animation with the word "erasing". So It looks like I have no recovery on the device. Otherwise, the phone boots up normally. Is there any way to restore the recovery partition on the phone?

Thanks for any replies.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dextructor:
After unlocking both H990DS and H990N with dirty Santa they continued to be indentified with their respective board names correctly so I believe that's you may have a problem with your initial setup.

The best solution it's to Partition DL again. Otherwise you could have other problems.

The second suggestion

I didn't test it, so it's up to you to try on your device at your own peril

. Both requires root:

A) Install TWRP app and if it support your V20 it can flash the recovery and later you can install Lineage Recovery.

B) Install Smart Flasher and flash your recovery.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] andruyd:
by any chance do you have other devices like smartwatch, oura ring, heart rate monitor, ecg, gps, glucose monitor?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] stsz1954:
Hello.

Finally, success. I connected the phone to LGUP. I used volume up, then connected the usb cable. It took me to fast boot then TWRP. It looks like on this phone Download mode has been replaced by the recovery image. Using a sdcard, I flashed the recovery image to recovery.I then installed LIneage OS.

Two more questions. I have a V20 with an AO Oreo rom on it. If I decide to put Lineage on it, do I have to downgrade to 91810p to keep all the sensors? Also, which version of Magisk is best for this rom?

Thanks for any tips.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
Did you update to the latest builds? The Bluetooth issue was fixed for H990xx.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] xxseva44:
Yea the hub issue is a known issue. It has to do with how overly complicated the usb setup is on the phone. More specifically it's related to how power is being handled, data itself is actually fine. Powered hubs will not work but anything that doesn't try to deliver power to the phone should be fine, so direct adapters and whatnot. But, other than crippled otg functionality it functions just fine.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] MarovEsnaen:
Yes. I'm on latest build. Maybe because i tried to replace fw like earlier post
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] MarovEsnaen:
Woke up today. Slept for 8 hours. I left my h990ds charging before sleep. And it hasn't even fully charged. Battery runs out. Then i'm about to charge it. Then i realize the phone doesn't even want to charge. I tried 3 different chargers. So i think it's happening to me too😁
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Envinite:
Welcome to the club lol. If your battery still have a little juice, you could connect it to charger then turn it on, it will start to charge once it boots up. But if it's depleted completely that you can't even turn it on, you're f*d. I just picked a new old stock V20 Charging Kit for $12 because this means I will be utterly f*d if my battery completely depleted.

I also need to note that I tried to upgrade to the most recent H990 build (lineage-20.0-20230917-nightly-h990-signed.zip) from last week build (lineage-20.0-20230910-nightly-h990-signed.zip). This was done via sideload, not the LOS updater. After flashing update my H990 that can only charge when it is turned on, now can't charge at all when it's turned on or off. Idk if dirty flash/ flashing zip is the same with download & flash through LOS updater, but if it were similar, that means H990 user could face charging issue if they update LOS as well.

So I had to roll back to Nougat. I'll try again downgrade with different Nougat KDZ and then go to latest LOS and see if it somehow fix it.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] MarovEsnaen:

This is just a curiosity, not really asking for an ETA or anything:

Any ideas if LOS 21 will be making it to the V20? If so, any insight if the new UVC webcam functionality in Android 14 will be functional?

We have no clue, 14 isn't even out yet.

And absolutely no clue.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] cr08:
Fair enough. From what I was reading it sounded like some 'general' development progress had started on Lineage's end so was just curious if there was any early info. I'll just have to be patient and keep tabs on any new updates. :)

Hey all, I am moving and therefore the unofficial update server/wiki will be down for a few days. Likely Wednesday, Friday at the worst.

Don’t panic when links in the OP don’t work, and your Updater app says something like “Can’t connect to server”. It is planned outage.

Hi Dextructer i need your help to update my LG v20 H990N on android 12 or 13
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dextructor:
There's no need to that multiple quotes without real need. If you never installed any custom rom on your H990N just read everything, and with some patience, you'll have Android 13 on your device.

There's no secret on using Lineage 20 on H990N (because it's the same procedure to any H990):

0) You need to exploit using DirtySanta so if your security patch level is before 2017, you are good to go, if not you need to Downgrade your firmware to H990N10b_00. If you need some visual guidance for DirtySanta you can use this video to better understand the process.

1) Download the latest required files (recovery + recent lineage build)

2) Following the instructions on the Wiki for the H990 install the build

3) Profit, be happy.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dextructor:
I and everyone are new in some way in something

I already gave you all the instructions that you need to follow in my other reply, with all the links, detailed threads for every step related.

I won't make a very super-rich detailed to the core instructions because:

Everyone has his own way of learning, and what's useful to me, may not be for you.

Every link that I inserted in my previous reply point to an important thread/instruction that you need to read with care and attention.

The video can help you understand the exploit process, but you are the one who will perform, not me, not anyone (unless someone are willing to be paid).

Please there's countless hours of everyone involved to make this happen, so respect the time of those who collaborate, and do your part as well.

hi, sorry if this had been asked before. I'm on h990ds android 8. I want to move up to los20. How can I do that? I tried searching guides to downgrade to android 7 but nothing so far
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] dextructor:
Hi

Yes this question has been answered before because every H990 variant it's vulnerable to the same exploit. Downgrade it's just using the appropriate KDZ file for your specific variant and from there you unlock the bootloader with DirtySanta > Install Lineage Recovery > Flash Lineage 20 following the instructions.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] kodomo hunter:
I tried dirtysanta twice, both failed with static screen after fastboot reboot

the first run was really messy, I ran the script 4 times in order to get certain steps right. It was because I thought I could use any android terminal, I installed termux because that's what I used to. But I didn't get the "untrusted_user" text after querying "id" to the terminal. I then proceed anyway but got error after running applypatch line. Long story short, the end result was a static screen after fastboot reboot

like this dude had https://xdaforums.com/t/solved-h990...boot-and-static-screen.3851681/#post-77832440.

before going to the second run. I "refurbished" my phone from lgup only to find an error. I installed uppercut based on the error and showed another error telling lg v20 connected is on different model. Then I do "update" instead of "refurbish" and it worked.

onto the second run, I realized maybe android terminal has to be specifically the terminal emulator from 2017. I redid exploit and this time it showed "untrusted_user". Sigh of relief, I proceed but was not able to pass the wait for dirtysanta logcat to return back then run step2.sh. Usual me just grind through even though something went wrong and here we go again back to the static screen like this dude had https://xdaforums.com/t/solved-h990...boot-and-static-screen.3851681/#post-77832440.

I could not make sense his solution as to what he did to flash the twrp. In which step do I need to flash then continue on the guide. Or do it before, but then that won't make sense because the bootloader is locked. there is no root. and didn't even run the exploit.

One major distinction is may be I did not downgrade to the same rom's region as this phone had. The guide said 10c, the only available ones are from singapore and philippine, but I assumed at the end of the day it's still the same phone, with just some apps preinstalled differently on different regions

Too bad. Sounds like it's only for H990. Is this fixable at all in future releases? I do have an H915 but I need to put it together as it's sitting torn down. Going back to to encryption, is that problem affecting all LG phones post LOS19 (including newer devices like V60)?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] npjohnson:
I'm a bit confused because this has worked for others, Yes we can likely fix it.

No, it's just the 8996 and 8998 generation of LG for encryption
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] andruyd:
Yea, I'm dumb founded. I've tried clean and dirty LOS20 install. Tried stock and swan kernels but this one wearable device won't connect with the phone. There's really no hacking or tweaking involved to get it working on LOS19. I just install the app that manages the device and it works. On LOS20, the app cannot find the device. It could be an app issue specific to LOS20 and I've brought it up to the developer but no response so far. For now, I will chill on LOS19.

Not related, will or when LG V60 will be supported for LOS?

Installed yesterday update (2023-10-15) on my H990N and I'm happy to report that Fix DT2W works now flawlessly. Before if I was using an application that kept the device running like music, or a phone call, I could DT2W, but without didn't work. Now it's perfect!

I didn't understand es9218: Introduce a customizable ess filter. Because it's already been foreshadowing the new settings for the DAC for some time now. But I was searching without finding it.

I could assume that it would take a little more patience from us, right?

Thanks!
[Android Q&A, Help & Troubleshooting] ILikeOldStuff:
I've got a couple of very old devices (used as wifi-only) that are starting to have issues connecting to modern websites. One runs FroYo, the other Ice Cream Sandwich. They are both rooted and I have ADB working on both of them. Some of the sites in question are using very little javascript, so even the old browsers on them used to connect okay until VERY recently. I have succeeded in updating the certs on both of these, which has helped with some web sites, but not all. The troublesome change seems related to certificate updates on some of the websites. Where they used to be using TLS1.1 and certs based on SHA1, they have changed to TLS 1.3 and SHA256, which these old devices don't support. There are also issues connecting to certain wifi networks, I suspect a similar cause for this too.

So, I want to update the version of libssl.so used on these devices. I have found some instructions on how to compile this, which looks like it will be an adventure unto itself (and maybe a separate topic for further questions).

One helpful detail about devices this old, they do not yet use dm-verity, so at least I will not need to bother about dealing with that.

Before I get too far down the compilation rabbit hole, assuming I manage to get it compiled correctly, is it really as simple as just dropping the replacement files into /system/lib ? Do I also need to update libcrypt.so at the same time? Or are there other items I would also need to update? Has anyone done this before, short of rebuilding the entire ROM?
[Android Q&A, Help & Troubleshooting] Avatar2:
I would actually be very interested in this (but for Jelly Bean). I can't get stock browser nor Chrome to work on my device because https connections no longer work on the vast majority of sites due to outdated TLS.
[Android Q&A, Help & Troubleshooting] ILikeOldStuff:
On my jellybean device, changing the browser solved it for me, at least for the websites I use.

The browser that solved it for me was Brave, see https://community.brave.com/t/what-release-of-brave-for-an-old-android/287742/2

I didn't even need to fiddle with the horribly outdated certs, since Brave has its own set packaged inside. Good thing too, since that device is not rooted.

Unfortunately for me, Brave never was available for FroYo or Ice Cream Sandwich.
[Android Q&A, Help & Troubleshooting] Avatar2:
Wow, I don't believe it. I just installed Brave on my old LG E-410B.. and I can go to websites again!! Thank you for resurrecting this phone!

[Touch Diamond, MDA Compact IV General] JRMX:
As already noted, sounds like you have System Vol up and have also gone into 'Settings/ Sound', and made sure phone volume slider is turned up.

I had the same problem for awhile, the two are linked, unless you manually turn the sound down (in Settings), then it will respond to the System level buttons only to the manually set sound level. I had inadvertantly turned my phone volume all the way down, thinking the System setting would adjust it to wherever I wanted it, not so and I missed some calls.:(

You probably have also checked to make sure the Phone ringer selection is not set to 'none'.
