I want to ask which kind of resistor is missing here on the second chip from right?
I've been looking around,but can't finded what is the corect name and parameters of that one.




You can simple short pad instead MB  M1 on schematic  but there is the reason why this element retorted. I think short inside chip or ceramic capacitor on left side MB.

First: took this module outside.
Moved the last onto his place.
Now can turn on miner.

Then make measure on the damaged PCB:
for a short on 7 pin  to GND and 3v3
If chip are damaged go to cellphone repair box, and swap  chip from last position U12 to U6.
Chip work in the chain and if you remove broken have 2 options:
insert new or one from last position
make wire connection
pin 1 to pin 36
pin 2 to pin 35
Before mount repaired PCB check for short on all chip (1V2  3V3 to GDN)

I hope this help.
