first: I thank you too much for your interest my friends, I appreciate this.
correction: the connector was 1x20 but this is not the matter, after I tried it with 1x18 immediately changed to 1x20.
using 1x18 cpu 1 pinouts are rx=12 tx=10,
using 1x20 rx=13 tx=11

anyway....
I tried all these things you are talking about. there is no power_a or power_b pins on the pcb. no rx tx pinouts on the pcb. (or I couldn't see them, and this is very little possibility). I think we aggree on that we are here to find solutions and help each other.
frankly infinity box doesn't cost that much money or the team must provide a wide database about phone and support more models.
it doesn't seem to happen.

again anyway.
after 20 days I'll have more time for these things. and now inviting you establish a team to build the needed database and publish it on the internet for members.
