Hi again. i get another pink macbook air with usb c port.. the target starts in dfu.. so i a try with "restore" but i get the error:
Error 4005
The OS Cannot be restored on this device.
Gave up waiting for device to transition from RestoreOS state to BootedOS State...
but its solder or flux? i think there is solder who melt with 58 °C... im using 138° bismute. Thanks for your time.. (in ebay only found flux chipquik)
Anyway.. i made the steps.. hehe
Trigger SMC_ONOFF_L (PMU_ONOFF_L):
I conect the power source and mac tries to start.. in the middle i "press" trigger the onof.. but nothing.. if i stay a few seconds the contact... it responses.. and the consume fall down.. (added powerz graphics)
Check PCH's...
