Short on vsys 4.2v

Hello. On my Nintendo switch HAD CPU 10 I have a short on vsys 4.2v. I have injected 1v 1a and nothing heats under thermal. I raised it to 4v and still nothing heats. I injected into the 2r2 coil between usb c and bq chip. Any ideas?

Ended up being the APU :slightly_frowning_face:
