Is SLA enabled? MT6789

[arifgore]

I have seen that mtkclient works with v6 devices unless DAA, SLA or Remote Auth are enabled. I tried with my device. In first section "SLA enabled" is false. But later, it says SLA is enabled and just hangs.

./mtk r boot,vbmeta boot.img,vbmeta.img
MTK Flash/Exploit Client Public V2.0.0 Beta (c) B.Kerler 2018-2023

Preloader - Status: Waiting for PreLoader VCOM, please reconnect mobile to brom mode

Port - Hint:

Power off the phone before connecting.
For brom mode, press and hold vol up, vol dwn, or all hw buttons and connect usb.
For preloader mode, don't press any hw button and connect usb.
If it is already connected and on, hold power for 10 seconds to reset.

until I interrupt it with CTRL+C. In that case I get the following error.

At this point I am not sure if my device is supported or not.

I encountered similar problems. Reading amd writing works here but not with using the MTK_DA_V6.bin. Try some other da file from some firmware for MT6789 device if you can't find one for your exact device.

[arifgore]

Oh, that worked. Thanks.

What DA file did you end up using? I've just been trying random files that are from MT6789 devices using --preloader={file} but it always says DAXML - Uploading xflash stage 1 from MTK_DA_V6.bin and fails.
