adb – Why is suggested to OEM unlock when LinageOS can be installed without it

I have a “LENOVO Tab 2 A10-30” which got frozen after the update in the startup loop – did not start after displaying the Lenovo logo.
I decided to reinstall it with the LineageOS, and for that I needed (according the articles) to do oem unlock.
According articles I should get the OEM unlock key from settings or allow it in the settings – which I can’t access as the device won’t boot up.

So I tried bunch of commands from the commandline (ubuntu 20.04), I could not OEM unlock, but I was able to install LineageOS just fine.
My question is – how come that it worked, even though it should not be able to unlock the OEM? What happened there?

Started device with holding vol up:

$ adb devices
List of devices attached
0123456789ABCDEF    sideload

Then I am not sure now what I selected in the menu, but then I went:

$ fastboot devices
84afc61e    fastboot

$ fastboot oem unlock
FAILED (remote: oem unlock is not allowed)
finished. total time: 0.002s

$ fastboot oem unlock-go
FAILED (remote: oem unlock is not allowed)
finished. total time: 0.002s

$ fastboot oem get_unlock_data
FAILED (remote: unknown command)
finished. total time: 0.002s

fastboot oem device-info
(bootloader)    Device tampered: false
(bootloader)    Device unlocked: false
(bootloader)    Device critical unlocked: true
(bootloader)    Charger screen enabled: true
(bootloader)    Display panel: 
OKAY (  0.007s)
finished. total time: 0.007s

But I tried to flash in the TWRP recovery image anyhow:

$ fastboot flash recovery recovery.img
target reported max download size of 262144000 bytes
sending 'recovery' (11700 KB)...
OKAY (  0.446s)
writing 'recovery'...
OKAY (  0.947s)
finished. total time: 1.393s

$ fastboot boot recovery.img
downloading 'boot.img'...
OKAY (  0.449s)
OKAY (  0.023s)
finished. total time: 0.471s

After that, with volume up on boot I got in to TWRP menu; where I installed gaps and LineageOS zips, and after reboot it was just there.

My research links:

terminal – Why is bash unavailable even though installed?

Your examples do not show that the shell you are running is zsh.

What they show is the default shell is zsh and the ps one shows you ran bash from inside a zsh shell.

$SHELL is the default shell and not what you are running (and that is zsh as you want)

For the process the $$ is the pid of what the command line sees e.g. trhe shell that runs the bash line you gave.

To see this

  1. Start bash e.g. bash
  2. In the bash shell now run ps -p $$ you get something like
    ~ bash
     bash-5.0$ ps -p $$
      PID TTY           TIME CMD
    28098 ttys000    0:00.01 bash
    bash-5.0$ exit

~ is my zsh prompt. bash is bash 5.0 installled via macports

Fonts are not displaying properly – after Google Fonts was installed via terminal

After Google Font installation browser of texts become "zzzEzzz"

The above picture tries to introduce that some websites are not reacting well of Google Fonts installation.
Originally I installed these fonts via terminal

 cd ~/Library/Fonts/
 git clone google-fonts

On the other day after the first boot-up I realised that both in Opera and Firefox were showing wrong characters mostly Z letters, see below.
When I simple deleted with the Font Book “Restore Standard Fonts..” everything goes back to normal.

Any command or modification which are capable to solve this thing is known?
Thank you!

virtualization – If Linux is installed in a virtual environment on my mac can I open apps that big sur blocks?

I’m trying open this application: (It’s a research tool might might be great for my work so I really want to access it).

When I try and open the app I get the message: “You do not have permission to open the application “ECGWorkbench’. Contact your computer or network administrator for assistance.”

If I installed Linux in a virtual environment on my mac could I then open the the Linux version of the app?

windows – Check if Second Level Address Translation (SLAT) is installed

There are different instructions online to show that you have Second Level Address Translation (SLAT) installed. The simplest way is to run “systeminfo.exe” in various Windows OS versions. How can I run this command without the command prompt from closing? When I run this, a bunch of text appears really quick and exits.

Do IntelĀ® Processors Support Second Level Address Translation (SLAT)?
- Press the Windows* key and type command prompt.
- Type systeminfo.exe.
- Check the Hyper-V Requirements section.

Also, does the “CoreInfo” program that Microsoft developed below give the exact same answer? I like to avoid installations for something as simple as this, so I’d rather not install CoreInfo.

Thanks in advance for any help.

ubuntu – Nginx/Apache installed but can’t see folder structure or files

I’m using a VPS and ubuntu for the first time and I need to host a website, I’ve got the VPS running and ubuntu installed but when I install apache or nginx everything works fine and I can see the placeholder site when I go to my IP address.

The problem is that after installing I don’t see any folders or files created by nginx when doing ls -a like the /var or /etc folders.

I tried logging in as root but that also doesn’t help, also I’ve tried to recreate the folder structure and add the files I needed but that also doesn’t change anything.

I’m trying to setup server blocks/virtual hosts but nothing is working as I can’t see nginx’s files and it looks like nginx can’t see my files. Hope someone can help.

xcode – How can I not have Command Line Tools installed, yet still have it?

$ type git
git is hashed (/usr/bin/git)
$ /usr/bin/git --version
git version 2.24.3 (Apple Git-128)
$ pkgutil --pkgs | grep ^
$ ls /Applications/
ls: /Applications/ No such file or directory

As you can see, I have neither the Command Line Tools, nor Xcode installed, yet I still have Command Line Tools. How is this possible? Is there something that I’m missing?

Where are kali linux files stored when installed using win-kex on Windows 10?

I have searched google and could not find this answer. I have also spent an hour at least combing through my AppData folder in windows 10 but with no luck. If anyone has any idea where I could access the virtual kali file system, I would greatly appreciate it!

I have checked this path so far: C:UsersUSER_NAMEAppDataLocal but with no luck. I have tried putting a unique file that only exists on kali and searching my entire machine for it but that does not work.
