I found this method, but the last step, when I understand it well, is where to get the vbmeta file from to flash it on the version of my device, especially as it is according to what its owner said that he tested it on the linux system and he has no idea if it works on Windows. If you know the vb.meta file, please let me know. What is his job and where did he get it?

I'm trying to flash lamma sweet kernel http://forum.xda-developers.com/g4/development/kernel-llama-sweet-kernel-t3286514 on a LG g4 h811 running Resurrection remix.
I've had nothing but trouble doing this with 2 builds.
It sends me to fastboot however I can't remember that fastboot said,
heres what fastboot says
FASTBOOT MODE
PRODUCT_NAME - msm8992_p1_two_us
VARIANT - msm8992_p1_two_us Toshiba 32GB
HW VERSION - rev_10
BOOTLOADER VERSION - N/A
CARRIER INFO - N/A
SERIAL NUMBER - LGH811[omitted]
SIGNING - production
SECURE BOOT - disables
LOCK STATE - locked
[1400]
[1450] Fastboot mode started
Click to expand...
Click to collapse
I have sence then done the following
1) tries to get into fastboot using all methods available to me.
a) using the button combo
b) using my reboot menu
c) using adb
All the above methods simply reboot the device. so I'm thinking I don't have fastboot anymore.
My setup.
- I'm using a LG g4 h811 on T-Mobile
- I use twrp as my recovery
- My bootloader is unlocked
- my developer options have allow oem unlock enabled
- I'm running official running Resurrection Remix http://forum.xda-developers.com/g4/development/rom-resurrection-remix-5-6-0-lg-g4-t3287313
- Here's my about phone

My ultimate goal is to flash lamma sweet kernel.

I have a Redmi Note 3 (INDIAN VARIANT Kenzo/Snapdragon variant running on Marshmellow 6.0.1 with MIUI Global 10.2) on which I performed an bootloader unlocking procedure via the tool XiaoMiTool V2 from xdahttps://forum.xda-developers.com/android/software-hacking/tool-miunlocktool-unlock-bootloader-t3782444 since the official method kept denying me for some reason
I also want to let you know that during the procedure i left the oem unlocking option disabled (off) and ran the tool
So after the device's bootloader was unlocked (ss attached)

I noticed that the OEM unlocking option was still active (meaning I can flip the button and it will just ask for the pass and warn me and enable the option: again ss attached)
Isn't supposed to grayed out ?
So my question is is my device properly unlocked? OR Did I mess up with procedure ? I know i could dial *#*#7378423#*#* (which doesn't work in miui devices) or using fastboot method mentioned here https://android.stackexchange.com/questions/73567/how-to-check-if-your-bootloader-is-unlocked and i got like
What does this mean ?
Any help is highly appreciated and thank you in advance
Once you enable the OEM unlocking in Developer options, in Android's system file build.prop the unlock ability flag is set to 1, what basically is requirement to start the bootloader-unlock procedure, what typically is carried out via Fastboot.
Typically you run
Code:
fastboot OEM get-bootinfo
to check if the bootloader is unlocked.

Implementations of Fastboot are different. Some subcommand may be supported, others not: that depends on OEM/Carrier.
Hello everyone!
This is my first post here so I hope everything I try to explain is according to the rules as far as I read it.
I need to root my Doogee S88 pro mobile since I need test and develop some AR stuff. The standard apps are not accesible by the playstore so I need to bypass that. For doing that I need to root my phone (this is what I read at least).
So... I installed the doggee usb drivers from their website for my phone, usb debugging is activated and OEM is activated as well. I downloaded the most recen platform tools and the usb-cable should be fine since I find the phone with
Code:
adb devices
I execute the following commands:
Code:
adb devices
adb reboot bootloader
fastboot devices
I get the small Fastboot text in the lower left corner. Then if I try to execute
Code:
fastboot flashing unlock
or
fastboot flashing unlock-critical
I only get back <waiting for device>
As said I installed the usb drivers provided by doogee. But: In the device manager I can see the following:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Also I periodically (every 10 seconds) hear the sound as if a usb-device is disconnected. Afterwards the device manager refreshes the list.
So... it is a driver issue? I tried updating the drivers but picking manually the folder where driver files are located leads to no result. Automatic search as well. If it is a driver issue - where can I get the appropriate driver files? Thank you for any hint.
Get the Google USB Driver | Android Studio | Android Developers
The Google USB Driver is required to perform adb debugging on Windows with Google devices.
developer.android.com
Unfortunately that didnt help either. Dunno... What I did was: I switched to my Lnux OS and over there it worked out of the box (only needed to install adb and fastboot from repositories).
