stuck recovery mode and few voltage on NAND power lines
After previous repair and using it 2 hours, it turned off. It is in stuck in recovery mode. Connecting it to my mac to try to recover it again, I could not enter DFU mode and recovering always resulted in error 4015 or 9.
I plugged in my DCPS on the battery line. And draws very few current 0.001 A which seems fine.
I am trying to rule out the power lines to NAND at the moment.
These are my observations:
- pp_batt - diode 0.26 (should be 0.4 i think)
- vdd_main - 3.7V - diode 0.26 as well
- pp1v8_io - 1.1 V - diode 0.24
- pp_0v9_nand - 0V - diode 0.4
- pp3v0_nand - 0V - diode 0.4
- Also battery was drained two 2.6V over night
What are my options to check?
