IPhone 6 I2C1 bus is not working properly
First we power our phones
Then the probe of the oscilloscope was connected to the test points of i2C1 SCL and SDA
Press start button
At this point, we can see that the current state is almost as abnormal as the i2c0 bus
The phone's working current swings back and forth between 0-60ma
The oscilloscope has no waveform
At this point the phone is not switched on
And then we connect the phone to iTunes
Get the reader firmware
We'll see a 4005 error message
