Switch Oled Picofly battery indicator problem

[VexareXx]

Hello.

Recently i have installed picofly modchip on my switch oled. The installation went mostly fine, i had some alignment issues on the nand side but after realigning it, it showed good resistance values. The modchip boots instantly to picofly toolbox but if i try to boot hekate then it shows low battery symbol. I have tried unplugging the modchip, nintendo logo shows up but shortly after that low battery and it shuts down. I have checked the battery, the voltage is 4.167V and that is near full battery right ? What could be the issue since the battery indicator is completely wrong ?

I have remembered one more thing, after the installantion, battery percentage was higher and it was booting to no payload.bin detected but i did not create the sd card files instantly but later.

I recall there are 2 resistors/datalines near the CPU that are required for battery information communication.
If you get no battery information in Hekate then the traces or resistors might be damaged.

The official firmware requires a good battery to start.
Afaik this is some sort of safety measure as bad/depleted batteries can catch fire.

Do you maybe know where exactly are those resistors located ?

Maybe it could be fuel gauge chip ? It also tells battery status.
