When support in nck [SECURE BOOT]
 

Hello i have many phone doro liberty 820 i try dump firmware and error

when update enabled secure boot ?

If model is not listed, use custom DA from phone firmware

logs are clear, now if you don t understand it then i prefer to take a short cut and say not supported maybe in future

As i'am see you have really no idea about, right? :confused:
Just for your knowlege.
Secured boot in supported in android mtk from 2011.
Before making post in tehnical forum, try to study little about subject.
Is not posible to make universal rsa key, is not posible to make universl firmware compatible for all phones, is not posible to make universal sim card what will work with all operators from all world, and list can continue.

Why is not posible is to many to explain, this is why i'am sugested you to learn little about what you talk, will be really easy for you to understand things after.

hello, I understand that there is no other software for this phone, except some universal software under mtk6582

Secured boot, meen loader is signed with unique rsa private key what is known only by team or person who maked this sign.
Usually this work in this way, we will generate private rsa key and will sign file(loader in this case).
Public key used to check sign we will share, but private key used to sign will remain secret.
To make universal solution, this meen need to make rsa key bruteforcing to find private key used to sign loader.
This meen huge amount of calculation power, here we talk about million of pc what work together for some years to find one key.
But here we talk about many many keys(each loader have own key).

This is why is not posible to make "universal sloution"
Only posible way if phone is secured, is to use factory loader what come with firmware.

I understand, there is no chance to do anything with this phone
