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?
