Switch Lite charges but won’t turn on

Hi!

I’ve failed to install a mod chip and now the console won’t turn on. It seems to be properly charging and I could find any shorts except below the APU(which seems expected). If I disconnect the battery and connect it to the charger, I can measure a quick 0.4A before going really low.

The only thing I can think may have caused this is that I forgot to disconnect the battery before removing some of the connectors and may have tried to connect the flex near the battery connector the other way around.

Any tips on how I can find out what’s wrong?

Thanks!
