How to trigger mtk meta preloader mode on this MediaTek device - MFDGaming - 09-01-2022

Its a MLS IQTalk Crystal Max phone. It has a MT6577 chipset. Ive seen other doing a circuit modification. I just need it cause I've formatted the whole flash so it doesn't go automatically to the preloader mode. I've confirmed that my USB cable and the drivers are fully working.

Is it detected at all on your PC?

It seems you'll need test points.
How did you format it exactly (which tool) and is the battery inserted / connected when connecting to PC?

I used SPFlashTool and used the format whole option and no the battery isn’t inserted.

connect the battery and check if the PC makes a sound (wait up to 5 mins).
You should at least get a detection unless the emmc is bad or something

I've tried using a multi meter in continuity mode and when i connected points to ground the multi meter showed 0L and and the computer never detected the device, from what i read in general there must be like an KCOL0 point. My device seems to have a point that is called "KC", on the screenshot i sent that label is hidden under that metallic cover that is for some sensitive components probably, and yeah there was just 0 response and the multi imeter showed 0L. The points i shouldn't try are like PWY, VBAT, VCHG, D+, D- so the only points left are KC (It is next to the camera flash) and some unlabeled points next to the board revision label (you could see it in the screenshot). What could i try doing?
