I think the domestik is right.

We must wait for the SPFT capable of sewing this model.
Sew the dead phone you need through the clamped "VOL +" button. Just the SP Flash tool can not switch it further into the desired mode.
And MiFlash does not react in any way.
In general, I took the risk. He unfastened the battery, all 3 points go tracks to the connector buttons. None calls to the ground. If you close the top 2, then for a second the computer determines something. Most likely this is the Mediatek USB Port, as well as when Vol + is clamped. The closure of the remaining points gives nothing. The ground is not closed, there is no resistor.
