How To Guide TCL 20 5G Unlock and Root - TCL 20 5G

Warning:
This isn't my method and I haven't tested it myself, Im just posting it in case it helps someone.
Procedure was taken from this article, so beware of auto-translation to english.
Even if it uses the MTKroot application and this phone is Qualcomm, it looks legit as it installs the Qualcomm drivers during the process.
All credits go to the original author (thanks a lot!), just pasting this here in case the site goes offline in the future.
I don't take any responsability and I won't be supporting any bricked phones.
Test it under your own risk!

Superuser or root is the usual name assigned to user accounts that have all rights in all forms of access, both monousual and multi-user.
Rooting a device is a method that makes it easier for the user of a computer with Android to gain privileged access to the system in a similar way to administrative permissions in Linux or Unix systems, allowing to cross any system barriers as well as software that could be established by the manufacturer or network operator.

I thought MTKRoot only worked on mediatek chipsets. These phones have Qualcomm cpus and gpus.

The situation looks like this: someone is messaging me about tcl-t810s, which is the model of my phone, and they need rom tcl-t810s, but they are giving me tcl-t767h rom instead. Could you please clarify what you meant by that? Perhaps, you could provide more information about what you are trying to achieve and why you are suggesting the rom for a different phone model. This could help us determine if the tcl-t767h rom is compatible with my tcl-t810s model and if it could solve the problem you are looking for.

The files were in a paid site. Gaby happened to have a subscription in that site and she shared it after I requested it. I can't remember the site's name but it only had those files regarding TCL models
