Charging current limit

[Rmdhn]

i do not know if this is my rom, but my charging current limit is set to 2300mA on sys/module and Redmi note 7 is QC 4.0 compatible with my cable QC 4.0 and the charger has a 3.A output, i wanna set the limit to 4000mA but i can't it's just hard and will always revert to 2300mA

I would be very wary of trying to change limits in something as sensitive as a quick charging system. There's a lot more to these things than pushing more current at higher voltages.

Does it revert instantly or when you try to charge it? A QC4 system can test the rating of your cable, and won't draw more current than that. And you've said yourself that your charger is rated at 3A, so doesn't sound like a QC4 charger (though QC4 can deliver 18W at 2A using 9V).
