Thanks for the help, I'm not familiar with Macbooks. I do have a working A1706 so hopefully that will be capable of the restore, will give it a shot tomorrow...

Hi guys, as the title. It turns on, charges, etc, but boots to the flashing ? folder. Once in recovery mode no drive is detected. I also noticed that the wifi signal is very weak. If it's over 2-3 meters from the router it will lose connection.

No signs of liquid damage, or anything obvious. All power rails are present with voltages and diode readings matching the boardview. Same with the following SSD related points:
I2C_SSD_SCL
I2C_SSD_SDA
P0V9_LX0_SSD0
P0V9_LX1_SSD0
PP2V5_NAND_SSD0
PCIE_CLK100M_SSD0_23_N
PCIE_CLK100M_SSD0_23_P
