Question Help Bricked 8i. Phone can't boot

[ClemALaVanille]

Hey there
Recently I've bricked my 8i and I tried many unbrick tutorials on here.
Unfortunately, it worked a little bit, it just boot looped since this moment.
Now I tried another thing to stop boot loops, and it just prevents my phone to turn on now and I get theses error messages when trying to use mtk_client

```
python mtk da seccfg unlock
MTK Flash/Exploit Client V1.6.0 (c) B.Kerler 2018-2022

DA_handler - Please disconnect, start mtkclient and reconnect.
