There is 8.1 oreo which you can install if you want

Hi nigxxx. That sounds good and I'll keep an eye on this.

 

[joriq]

when you have root access and twrp you can do whatever you like... just be careful that you use everything for H815. there is 8.1 oreo which you can install if you want

which rom would that be?

 

[Ponder Stibbons]

which rom would that be?

Maybe

But please pay attention to https://www.reddit.com/r/LineageOS/comments/83wqdp/project_fi_and_gapps_inside_lineageos/

LineageOS: Proprietary Google components in code?

On Reddit, a disturbing message is making the rounds: Project Fi and Gapps inside LineageOS.

In LineageOS 15.1 (Android Oreo) some closed-source Google components seem to have found their way into ROM. It is unclear whether it only affects LineageOS 15.1 in combination with the Nexus 5X. Which apps / services are installed:

Google Connectivity Services
carrier services
Project Fi
X Google
T Google
OK Google

Quiz question to the LineageOS maintainers: What is one of the reasons why people install LineageOS?
Answer: To break away from the Google ecosystem and get rid of proprietary garbage.

If you want to continue using Google, you can optionally flash the GApps or an alternative.

It is incomprehensible why such decisions are made and closed-source components are integrated into LineageOS. My advice: Check this on your LineageOS installations: Settings -> Apps -> Display system processes.

If you make similar discoveries, you are welcome to send me an e-mail. And if you have the leisure, you can look for the changes in the LineageOS code.

at the time of writing my post, that rom was unavailable, there was just an announcement. Also, now, 4 days later, there are no comments on the thread, so I think it's a bit early to install 8.1 on G4s as a daily driver.

Uploading TWRP recovery via Windows 10

I have a problem with the command fastboot boot lgg4-twrp.img
After entering this command, my smartphone does not allow me to enter the recovery mode. The situation in the smartphone is like on the screenshot IMG_20180415_200134
According to the guide, the smartphone should start again and enable twrp not yet installed.

The situation in the Windows cmd console is as it is on the Screenshot_3 screenshot

I am asking very kindly for the support of the Honorable Author of the topic and other forum users.

I send cordial greetings to all who read this topic

I have a problem with the command fastboot boot lgg4-twrp.img
After entering this command, my smartphone does not allow me to enter the recovery mode.

iv) Enable USB debugging again

At first try the following command:

adb devices

You must see an output like this

List of devices attached
XXXXXXXXXXXX device

Maybe you have waited too long between the two commands. Use Copy-n-paste.
adb reboot bootloader
fastboot boot lgg4-twrp.img

vii) In the command window, type "adb reboot bootloader". Wait to enter the bootloader and then type "fastboot boot lgg4-twrp.img" and hit enter. The device should now restart in TWRP but it is not installed yet.

I have such a short question.

How to check if I have properly installed the minimal ADB and Fastboot.

So drivers and the management program itself?

Minimal ADB and Fastboot downloaded according to the guide from this link> https://androidfilehost.com/?fid=24521665358595410

I kindly ask you for an answer.

 

[Ponder Stibbons]

Do you have installed first the Driver for your H815?
The Driver you can find in the first posting of this thread.

That's looking good. I am not familiar with Windows. I think your driver is properly installed when your command "adb devices" gives you an output like this (important is the last line).

adb devices

That's exactly a use case for FWUL..

Good Morning,

I am not familiar with the meaning of FWUL because until today I didn't know it. Google told me that sounds like "Forget Windows Use Linux". Yes I agree 100% with you.

Dear steadfastX

I am asking you with a very kind request for your support.

I have a situation like the video here link> https://drive.google.com/file/d/14Waz5NFwboJ1hX2_3ZZS-JAJEp5-q2ub/view?usp=sharing

According to the commands described below - TWRP probably signed up to me

temporarily or permanently. I think permanently - because after restoring the settings

factory - you can see on the video that TWRP appears when you start Smartphone.

I am asking you with a very polite request for a detailed explanation

described in simple language, why TWRP recovery has been in memory - despite

that I have reset the smartphone to factory settings.

use the latest TWRP version and not a totally outdated one.
latest is here: http://leech.binbash.it:8008/TWRP/N/

Dear User steadfastx

Thank you for the message.

Is the latest TWRP Recovery from this link which

you gave me> http://leech.binbash.it:8008/TWRP/N/ also need to change

the same name from twrp-3.2.1-PREVIEW-109_g4_N.img on lgg4-twrp.img?

I have to understand that I can follow this instruction> https://forum.xda-developers.com/g4/general/howto-complete-guide-to-unlock-twrp-t3370003 ?

Can you download Salt applications on Windows - which

allows you to make a backup?

Whether to do an Android backup you can use Linux launched from PenDrive

possibly if the Salt application on Windows is not available?

Dear steadfast X if now I have TWRP which has been installed on the recovery partition, do I have to first uninstall it present or restore it to be without Recovery or Can You Install it from your link to it present?

Hello, is my phone recoverable? I do not have a connection to Fastboot in the cmd console. After pressing the power button Power - the smartphone stands on the LG logo and blinks with a diode. Is there an additional reset button in this smartphone - in addition to opening the battery cover and removing the battery? Is there a combination of buttons that triggers an additional reset? I have a situation like the video at this link> https://drive.google.com/file/d/1rpDaLVVsFQVCAOTiH7ZMyV8wRDmk_SKV/view?usp=drivesdk

i) Make sure you have the LG Drivers installed from here: http://oceanhost.eu/e4h2px4e0hkd/LGMobileDriver_WHQL_Ver_4.0.4.exe.htm

ii) Download the LG Bridge software from here: http://www.lg.com/us/support/product-help/CT10000025-1438110404543-preinstall-apps

iii) Remove the battery and reinsert it so the device it is fully off.

iv) While holding the up volume button, insert your USB cable.

v) You should enter download mode. Go to the Software Update tab of the LG Bridge. It will say connecting and then should say your device is up to date. Click on the recovery text on the bottom right and then follow the instructions. The software will download the system image for you and this is roughly 1.6GB so make sure your firewall doesn't block this connection.

This may delete the files on your phone.

Hello, please, write me how to block Bootloader ?

Dear author of the topic

I am asking you with a very kind request for your support.

I tried to block the bootlader with the same method as you can unlock - with this one

that I changed the name of the file that I received on the email from unlock.bin on lock.bin.

In cmd I also entered the command fastboot flash lock.bin.

Unfortunately, but the cmd console replied to me with this message:

unknown partition 'lock.bin'

error: can not determine image filename for 'lock.bin'
