This is common issue that no one willingly to solve. I hope someone can provide solution to solve handshake failed, because i do not know how to solve it, even my chipset is not in v6 list, and there are da file that's exact to my chipset :/

sadly it didnt work for me

[r4db]

i tried mtk bypass. It didnt work it just said "waiting for device" even after plugging it in

Check if it support by mtk bypass. Example, Helio P70 are being supported. I remember when i tried unsupported MTK SoC on mtk bypass, it just draw paragraph of code error

i think i have found my problem #830 but my question is how do i get da and auth file for this device?

[NasiGorengBurung]

In mtk thread, xda server. Some people said...

try running mtkclient and see if it runs successfully. If it's stuck or gives out an error even if you've successfully downloaded all dependencies and run BROM properly. You can get the bypass utility here and the payloads here (Put it in a way so that default_config and main.py in the same folder), it supports several more than the listed SoCs, one way to figure out is to find out is to run the bypass utility with -t and try to find your hardware code on the default config file

[NasiGorengBurung]

Follow the default config and main py stuff. It will expand mtk bypass soc support lists and it might support your soc

[NasiGorengBurung]

Also "figure out" part too

For da: https://androidmtk.com/mediatek-da-file

For auth. Follow steps for mtk bypass i said, after do step. Do on mtk bypass

[NasiGorengBurung]

Maybe run mtkclient with da file after auth step

thanks will try when i have time

[NasiGorengBurung]

You know, i decided to help you further, because i know how to feel to have hard time to save phone from being bricked

[r4db]

Follow the default config and main py stuff. It will expand mtk bypass soc support lists and it might support your soc

i did all the steps you mentioned but same thing "waiting for device" even though my cpu is supported mt 6853 i also tried to use those other apps like auth bypass but with gui it detects the device but with error "slaa/daa error" or something like that on device manager it shows up as this

i also tried mtk bypass on linux same problem

[NasiGorengBurung]

Well then, sorry to break it to you. I have similar problem as yours, and i have no clue how to solve that

Do not worry. There are another chance, in XDA server, there are thread that help you to get phone from bricked, and there's helper that's familiar with MediaTek https://discord.com/invite/xda-422814981520621569

where do i get loader and auth? also can i use testpoint to enter brom? @bkerler

[bkerler]

As the readme already states, fused devices with V6 aren't supported right now.

[bkerler]

As oppo devices are total crap, even if you have auth, you cannot write anything without special permission/token.

I agree, but what fused mean?
