Hi! I’m fighting with switch oled:
Initially was no 1.35v on max77620h IC. After replacement of power gauge (I found crack) and IC itself - it’s now boot to hekate and have 1.35v.
But…
I can’t boot to atmosphere / ofw whatever it’s on emummc / original - black screen after logo.
Consumption rises to 173-180mA while boot (ive adjusted autoboot to atmoshpere on mmc to do it without screen attached) and drops to 153mA after. (10k resistor simulates battery + 4v from bench power supply)
I’ve:
Checked MMC for speeds - 370MB/s + all green.
Battery status - all looks fine - shows discharge rate + all power statistics.
Re-created MMC from fresh HOS and dump (done backup before) and flash it back. Same stuff happening.
Also:
Replaced MT92 - same stuff - 15v triggering - no problem, same behavior.
Charging is working bq seems to be alive - but who knows…
As well as:
Checked shorted caps, inserting voltage with thermal camera…
Max77812 has only 0.6 + 0.8 on right inductors.
Any ideas from masters of fix? 
Thanks!
