Android - Rooting ? - Bootloader unlock? - Custom ROM ? What is the order??


Rooting your Android? What is rooting?? Unlocking the bootloader ??? Confused!


Root

The term root in the IT world initially came from the UNIX / Linux Operating Systems.  New stand-alone Android is built on top of the Linux OS. The root is equivalent to Administrator in Windows. So root access is administrative access to the file system. The root can add, edit and delete system files.

The root has the ability to change system files such as installing a system-wide ad-blocker by modifying the host file on your device, or uninstalling system apps, such as bloatware that comes pre-installed on your device. Without the root, one can only see files in the root directory instead of editing them.

Rooting

Giving administrative access to the entire OS.  

Bootloader

A bootloader is a firmware, very similar to BIOS in a computer. It initializes the Linux kernel and loads all the necessary components required to boot into the Android. And it manages direct access to the device's partitions.

Unlocking The Bootloader.

Unlocking the bootloader enables the user (root) the right to do some modifications in a device like flashing custom ROM, recovery etc.

Teamwork - Bootloader And Root

A locked bootloader also locks write access to several partitions like the system partition. This is the reason why just rooting is not able to add, modify or delete system Apps without an unlocked bootloader.  Root needs write access to the system partition. Without an unlocked bootloader, the root can only do limited tasks.

Custom ROM

ROM is Read Only Memory, just like in CD-ROM or BIOS in a computer or bootloader in mobile. 

In mobiles, the operating system is installed in a ROM. Pure Open sourced Android is developed by Google. Mobile manufactures use that source code to brand and enhance the OS for their offerings and installed in the ROM. Then that ROM contains the Manufacture supported OS. Developer community also provide more customised OSes for those devices called Custom ROM. 

Tools In The Trade

How to unlock the bootloader

Use one of these 

ADB and fastboot tools. Download it from the official Android developer website.


Just to root the device:

Magisk, TWRP, SuperSU

For older devices use Kingo Root App

Use Kingoroot Super User to unroot it back.


Hope this will help to understand basics.

How to change password length requirement in Umbraco

Change the password length requirement in Umbraco This solution will work with Umbraco 8.xx versions. Previous or newer versions may need some additional or fewer changes.  In Umbraco default password length is 10, and need to provide a valid email address for the user name.   If you are developing or designing a website using Umbraco and testing it you may need to shorten the password length or use a short username in your development website to save time. (NOT in the production site) Changing default password length in a new installation This method is for a fresh Umbraco installation. For an existing installation, there is some extra work to do. I will discuss it later. Lots of people have an issue with changing the configuration to suit this requirement.  First, we will look at the issue.
