[LG V20 Questions & Answers] ignoll:
Hello,

First off, thank you for clicking on this post. I'm new on XDA and rooting LG phones. However, I've searched help on posts and other sites on how to root LG V20 H19810k (T-Mobile Variant) and many told me to downgrade first and then root. But none exactly gave any instruction or step by step on how to do it.

My worries are these ARB (Anti-Roll Back) software updates and if you were to downgrade, you will brick your phones and things like that, it's LG (I mean like there are a lot of complains about hardware faulty after phone updates and lawsuits about it), and different steps on each variants. I bought this phone like 2 or 3 months ago, and my thought on this phone's software is sucks so bad. It's so bad, I've had many problems like my mobile data often times stopped working (no network) even though signal is full bar, my live pixel background suddenly gone after playing this specific game, serious low fps in some games, RAM is full all the time, and many more. The phone itself has amazing hardware and specs, but damn why is the software so bad?

Right, so all my problems aside, I think switching ROM or downgrade probably a good idea and rooting for removing bloatwares. But many had problems installing twrp recovery to root and risks like bricking and bootlooping. And in this post, I'm hoping for help to downgrade and root H91810k.

Search this forum there's numerous threads on how to root
[LG V20 Questions & Answers] runningnak3d:
Downgrade to 10j and use DirtySanta, or use lafsploit.

IMHO they are about equally difficult. In the lafsploit thread, I state that you have to be on 10p or 10q, but I will update the post stating that you need to be on 10q or LOWER.

DirtySanta doesn't require you to use FWUL, so it does have that advantage.

Bottom line though, you can't stay on ARB 0 firmware and use any of the current ROMs -- they all require 10p or higher firmware.

Thank you for the reply,

Seems I got it a little bit. So what I've been looking at this dirtythis and that unlock stuff for quite a while. I've been wondering if anyone asked about H918. I just realized that this dirtysanta bootloader is an exploit for other variants that don't support unlocking via fastboot.

So then I proceed to unlock my device and it successfully unlocked. (Follow this post to unlock).

I will try downgrading my device via lgup and will follow this post to flash and root.
[LG V20 Questions & Answers] cnjax:
Be careful about your rolling back to root, check your current software version and and if you're arb 1 you'll brick. If you're arb look up the laf exploit thread
[LG V20 Questions & Answers] runningnak3d:
He said he is on 10k, so he is safe to rollback to 10j which can use recowvery.

[MENTION=8965480]ignoll[/MENTION] Whatever you do, DO NOT flash the engineering aboot, or you will brick your phone. Follow the procedure in the post you linked, and you will be fine. DirtyCow gets you a temp root shell that will allow you to dd TWRP onto the recovery partition. If you get an error when you do run-as con, then you are NOT on 10j or lower. If you try to downgrade and you get an error about ARB, then you are NOT on 10k.

Just keep all that in mind and you will be fine.

-- Brian
[LG V20 Questions & Answers] ignoll:
Thank you for the reply,

Just to make sure, 10k is the software version which you can find in the software info inside the settings app, right? This software info will show stuff about "Android version", and down on the list, there's the "Software version" and below it is the 10k coming from (H918xxx). Or, check it via svc menu and version info through the dialer app. All that is to check whether I'm in the correct version or not, yes? (Sorry for this silly question, I just want to make sure. I'm really new to this)

And yes, I won't flash this engineering aboot, just follow the instruction and I'll be good. But just to make sure again, there's no this "engineering aboot" thing in the post that will brick my device, yes?

That said, I really appreciate for your warning and advice.
[LG V20 Questions & Answers] runningnak3d:
Yep, that means you are on 10k, so you are safe to rollback.

-- Brian
[LG V20 Questions & Answers] kenneth excellence:
Please, i am also stuck and confused, as i understand LG devices, downgrading may cause device to go dead completely, i want to be sure before i begin this process. Here is my device Software Info:

Software Version: H91810K

Build Number: NRD90M

My device is locked to T-mobile, and i want to unlock using Octopus Box as i have credits. Unlocking requires root, is it possible to downgrade to the mentioned version 10j and not brick device? Any one can help me on this.
[LG V20 Questions & Answers] cnjax:
If you root your phone it will be unlocked no need to use an octopus box.
[LG V20 Questions & Answers] runningnak3d:
That is only true if the engineering bootloader is used. The H918 still needs work to get it carrier unlocked.

-- Brian
[LG V20 Questions & Answers] kenneth excellence:
Are you serious? If this is possible how do i root since i am on H91810K Software version?
[LG V20 Questions & Answers] Hash-82:
He is serious, but incorrect.

You need to pay attention to runningnak3d when he says something about root and the V20.

I might be nitpicking here. But I have screen protector in my note 8. I woke up this morning with a black line.

Is this black line a dust or a Scratch?
[Samsung Galaxy Note 8 Questions and Answers] Cool Person:
Here it is
[Samsung Galaxy Note 8 Questions and Answers] POLO_i780:
That looks like a piece of dust/lint under your screen protector.

What sort of screen protection is it? Tempered Glass?
[Samsung Galaxy Note 8 Questions and Answers] Cool Person:
Tempered glass yes. I Can live with it if It's not on actual screen. I am new to edgw screen so excuse me for being paranoid. So it's not an actual Scratch?
[Samsung Galaxy Note 8 Questions and Answers] POLO_i780:
It does not look like a scratch to me.

Scratches usually tend to show as a multicoloured line due to the LED below the display glass, that is a Black line that looks like a bit of lint / dust that got under the screen protector, possibly during application or slipped into a part that is not totally sealed around the protector.
[Samsung Galaxy Note 8 Questions and Answers] Cool Person:
Thanks for telling me cause I am a bit of a noob when it comes to telling the diffrence. The phone is awesome by the way. Coming from note 5.

Hi

I have a rooted phone, and received the ota update, but when phone reboots, it goes boots to twrp .

Since ff is approved, could someone pls advise how to update via hwota8

kind regards
[Huawei Mate 9 Questions & Answers] ante0:
Flash stock recovery.

For HWOTA8, follow the thread. You need to download FullOTA.
[Huawei Mate 9 Questions & Answers] mp187263:
Also with HWOTA8, you will not need to flash stock recovery manually. Basically you flash the zip from TWRP with the provided stock recovery and the three FullOTA update files from Huawei located in a HWOTA8 folder on your external SD card. Once the update is completed, you can then flash TWRP and root again. Same process for every update. Bootloader stays unlocked.

Here's the thread: https://xdaforums.com/mate-9/how-to/guide-mate-9-flash-oreo-update-package-t3699522/
[Huawei Mate 9 Questions & Answers] the-light:
Hi mp187263

Thank you for your reply, I also think updating via hwota8 is better solution, having said that, there are 4 file downloaded from ff 3 of them are with l29 and one is l09.

could u pls advise if i should dl and flash the 3 files all together with hwota8?

many thanks
[Huawei Mate 9 Questions & Answers] mp187263:
You should only have 3 files, that are specific to your model. FF gives you the exact download links you need as long as the correct model is selected.

If you can get into the OS, it will be under Settings > System > About phone (example: MHA-L29 with the build number showing the region - ie. C636). Or a better way is to get the FF app and it will show you the model as well as the region. If you cannot get into the OS and your phone has not been rebranded, it will be on a label on the original box. My phone is from China so it came as a MHA-AL00, but was rebranded to MHA-L29C636 (International version). There are also other versions such as C567 for USA and so forth. The files you download have to match exactly what you have, do not flash it if unsure.
[Huawei Mate 9 Questions & Answers] the-light:
Thx again for clarifying. im on c567, I didnt know if i should flash all 3 files, now I do..btw, there is a new patch coming in soon, .369, guess ill wait for it to be approved and then make the flash
[Huawei Mate 9 Questions & Answers] drift08:
I flashed the EMUI stock recovery but OTA update still fail. Any idea? Thanks.
[Huawei Mate 9 Questions & Answers] ante0:
Any modified partitions? That would most likely be why, and you'd have to flash FullOTA if that's the case.
[Huawei Mate 9 Questions & Answers] drift08:
I think I reflash EMUI to ram disk recovery via adb but still have root via magisk. When you say FullOTA, will it erase all my apps and accts? Thanks.
[Huawei Mate 9 Questions & Answers] ante0:
Difference between OTA and FULLOTA is that OTA patches existing partitions while full flashes full images. Your data will stay untouched

Hi guys,

As the title suggests, I'm looking for a decent Android head unit that will fit a single-DIN slot and will run both Waze and Viper4Android. This is to be fitted to a BMW E36 and I plan on doing some cool stuff with the Convolver.

Does anything fit the bill? I don't mind if it's an older model running an older version of Android, as long as it can run these two apps. Oh, and Spotify!

Thanks

[Samsung Galaxy S9+ Questions & Answers] jfm91:
Hi.

I have the S9+ G965F with two sim-cards. Sim 1 is for calls and sms. Sim 2 is for data. However the phone does not allow both cards to use the 4G network.

Sim 1 is on 2G/3G network

Sim 2 is on 2G/3G/4G

So obviously VoLTE dont work for Sim 1. I didn't expect anything else.

But it seems that Wifi-calling (Sim 1) doesen't work either when Sim 2 is set to 2G/3G/4G

If I set Sim 1 to calling, sms, and data both VoLTE and Wifi-calling works.

Is there any fix for this?

I am on stock (NEE CSC) rom. I have root and custom kernel (Flash Kernel)
[Samsung Galaxy S9+ Questions & Answers] t-shock:
This is how Samsung implemented the Dual SIM ability on this phone. We cant do anything to change it

As far as I remember, Huawei Mate 10 Pro was the only phone that I used and it had dual VoLTE (thus VoWiFi) and it didn't matter which card you had for data
[Samsung Galaxy S9+ Questions & Answers] jfm91:
Does this mean that no future software will be available to enable this function?
[Samsung Galaxy S9+ Questions & Answers] xpdragon:
Huawei Mate 10 (non Pro) also supports dual VoLTE. I believe it is the same for P20 Pro. Samsung is behind in this area. Hopefully, S10+ will have this feature.
[Samsung Galaxy S9+ Questions & Answers] maciej84:
Hello. I am bumping this up, because I'm considering buying a Dual SIM S9, but I need WiFi calling on one SIM and mobile data on the second one.

Maybe someone could confirm whether with the OS upgrades (currently Android 10 I think), this issue has been fixed? Is it possible to have WiFi Calling on the first SIM and mobile data active on the second one?
[Moto G6 Questions & Answers] renatofontes:
Can anyone confirm? It seems that the standard G6 will come with a 32-bit version of android, which could **** up compatibility with treble roms. :(

Edit: went through a lot of youtube videos until I found one of antutu stating that it is the version compiled for ARMv7. So yes, it has a 32-bit OS.

:(
[Moto G6 Questions & Answers] nicnic94:
Processor is 64 bits so strange that the os could be 32 bits
[Moto G6 Questions & Answers] renatofontes:
Well, they did the same with the G5 Plus
[Moto G6 Questions & Answers] manos78:
Yes!

And before having one unit for testing, two comments:

1) In the ARM platform, the difference between 32bit and 64bit ABIs is marginal. So no big speed improvements when using the 64bit ABI. However, the RAM used is increased when using the 64bit addressing.

2) As one model of Moto G6+ is announced to have 6GB of RAM, this implies a 64bit kernel. Then, you can derivate that Motorola-Lenovo will not create two ROMs for the same device, and a 64bit only version will be available.

Regards.
[Moto G6 Questions & Answers] smitharro:
Hereby a screenshot of my Moto G6 Plus. Under 'besturingssysteem' (Dutch for 'operating system') it clearly sais under 'architecture' 64 bit. Don't know about the non plus version. By the way. My phone has 4gb of ram.
[Moto G6 Questions & Answers] GuestD0601:
Well, Geekbench Browser tells me that G6 Plus is 64-bit while normal G6 is 32-bit
[Moto G6 Questions & Answers] manos78:
Probably,

The Moto G6 and the Moto G6+ are different smartphones. The "regular" version (G6) uses the Snapdragon 450, and the "plus" version (G6+) uses the Snapdragon 630. Perhaps motorola implements the 64bit ABI in the G6+ because a 6GB RAM version will be available. And as the G6 will only be up to 4GB RAM, then it will "optimized" to use the 32bit ABI.

Remember: 64bit ABI in ARM is not a performance increase!
[Moto G6 Questions & Answers] PeterImmel:
Here my Moto G6 - 3/32GB
[Moto G6 Questions & Answers] manos78:
So, confirmed: Moto G6 uses 32bit ABI, and Moto G6+ uses 64bit ABI.
[Moto G6 Questions & Answers] smitharro:
Yes, an essential difference! Glad to have the Moto G6+...
[Moto G6 Questions & Answers] allrightlite:
And an another important point is that just the G6+ (snapdragon 630) is whitelisted by netflix for playing movies in high definition. That's right, or? So, G6+ is not a bad deal. Treble support is there on 32-bit and 64-bit OS version?
[Moto G6 Questions & Answers] renatofontes:
Yes, both have treble support. There are some compiled versions of the treble roms for 32bits.

I didn't get to test it because my Moto G6 had some screen issues so I ended up returning it before unlocking the bootloader. Though I initiated the process in Motorola's page and the bootloader seems to be unlockable. :)

i have downloaded "KitChenROM Core_19199 (Build 19199) and Core_19716 (Build 19716)" and followed the tutorial on the wiki for that. everything went fine. i made a few phone calls yesterday, and it was still fine. this morning i grabbed my phone when i woke up, and checked for text messages (it's on silent when i sleep), and it was still working fine. i got to work, and i grabbed my phone to see the time, and it was black, and stayed black. after replacing the battery it went to the t-mobile screen (mda vario, netherlands), and gives me this information:

IPL: 2.26

SPL: 2.26

GSM: 02.25.11

autorun guide (russian-use Google translate webos-forums.ru/topic4650.html )

Как добавить приложение в автозагрузку, чтобы при включении ТВ оно автоматически запускалось?

Разберем на примере ForkPlayer.

КОД: ВЫДЕЛИТЬ ВСЁ

busybox chroot /proc/1/root

ls -l /media/cryptofs/apps/usr/palm/applications/

Ищете папку форкплеера

Если нашли делаете:

КОД: ВЫДЕЛИТЬ ВСЁ

cat /media/cryptofs/apps/usr/palm/applications/папка_форк_плеера/appinfo.json

Ищете надпись типа:

КОД: ВЫДЕЛИТЬ ВСЁ

"id":"es.ottplayer.widget"

Это у меня ottplayer.

Запоминаете копируете надпись после "id" (без кавычек)

Затем при помощи редактора vim редактируете файл

КОД: ВЫДЕЛИТЬ ВСЁ

/media/cryptofs/apps/usr/palm/services/com.palmdts.devmode.service/start-devmode.sh

Добавив после #!/bin/sh строку типа:

КОД: ВЫДЕЛИТЬ ВСЁ

luna-send -n 1 -f luna://com.webos.applicationManager/launch '{"id": "com.webos.app.mystarter", "params":{}}'

Только вместо com.webos.app.mystarter вписываете свой id форк плеера.

How do I add an application to autoload so that when I turn on my TV it will start automatically?

Let's look at ForkPlayer for example.

busybox chroot /proc/1/root
ls -l /media/cryptofs/apps/usr/palm/applications/

Looking for the forkplayer folder

If found doing:

cat /media/cryptofs/apps/usr/palm/applications/folder_fork_player/appinfo.json

Looking for an inscription type:

"id": "es.ottplayer.widget"

I have this ottplayer.

Remember to copy the inscription after "id" (without the quotes).

Then use the vim editor to edit the file

/media/cryptofs/apps/usr/palm/services/com.palmdts.devmode.service/start-devmode.sh

Adding a line of type after #!/bin/sh:

luna-send -n 1 -f luna://com.webos.applicationManager/launch '{"id": "com.webos.app.mystarter", "params":{}}'.

Only instead of com.webos.app.mystarter type in your forkplayer id.

If you don't know how to use vim, learn how to use it. :)
[WebOS Software and Hacking General] LukeStage:
With rooted LG Tvs (https://rootmy.tv/) I think is possible a way to autostart an application on startup because in https://github.com/RootMyTV/RootMyTV.github.io there is a text that says:

​

​

I have connected my computer with LG TV via SSH (using WinSCP). LG TV IP, user: root password: alpine​

I´ve checked the file start-devmode.sh, and after rooting the TV the text says:​

​

by the way, the content of the startup.sh is https://github.com/webosbrew/webos-homebrew-channel/blob/main/services/startup.sh#L77-L80

Then I have created a file .sh to austostart an application (the id of the application is com.telefonica.app.nux) on startup in /var/lib/webosbrew/init.d/ directory, but it not works.​

The content of the file is:​

​

But nothing happens when I reboot the Tv. It starts normally. Do I need to add more lines in the file .sh? I have no idea of Linux but I think what I have done it correctly to start an application on startup.​
[WebOS Software and Hacking General] LukeStage:
Solved to start a program when starting the LG TV.

The file does not have to have any extension and no strange characters. The content will be this (com.telefonica.app.nux is the application. To choose another application that we want to start we must know its id, which comes in one of the appinfo.json files that comes in the folders where the application is installed):

luna-send -n 1 -f luna://com.webos.applicationManager/launch '{"id": "com.telefonica.app.nux", "params":{}}'

We place the file in the path /var/lib/webosbrew/init.d/ of our TV. It has to have all the permissions enabled (we can copy the file startup.sh that is in the folder above, rename it and edit it to have a file with all the permissions or attributes enabled).

We disable fastboot in the TV Options.

The only downside is that the program takes a few seconds to start (in my case it took 8 seconds from the moment the TV is turned on).

For those who use a telnet terminal with commands is tedious or have no idea (like me), you can use the WinSCP program that connects perfectly (IP of the TV, port 22, the user is root and the password is alpine). It has Windows interface and options to copy or edit the files without any problem.
