Hi, I have this 820-01700 board, which I replaced with a donor T2. When I power it, the board is in DFU mode. Soc_dfu_statu is 1.8V. I try to restore it with Apple Configurator, but it gives me this error: "Unexpected device state 'DFU' expected 'RestoreOS'" Error 4014.
I checked all the AWAKE and SLPS2R voltages, and they are all there.
PP1V2_AWAKE 1.2V
PP1V8_AWAKE 1.8V
PP3V3_AWAKE 3.3V
PPVDDCPU_AWAKE 0.755V
PPVDDCPUSRAM_AWAKE 0.802V
PP0V8_SLPS2R 0.800V
PP1V8_SLPS2R 1.8V
PP1V25_SLPS2R_SMC_AVREF 1.1v
PP1V1_SLPS2R 1.1v
However, I don't have any voltage on the SSD, PP0V9_SSD, PP2V5_NAND, or PP1V8_SSD. I don't know if this is normal. However, in diode mode, I'm measuring a slightly low value on PP2V5 and PP0V9, which then returns to a high value as it cools. I compared it with another card, and this isn't normal. What can I do?
