iPhone won't recognize original BMS after battery replacement

Hello everyone, after replacing my XS battery cell for a new one, the iPhone keeps showing Important Battery Message and won't show the maximum capacity. Here's what I did:

-Got a new battery cell without BMS and installed the original BMS using Qianli Spot Welding Machine

-Reset the cycles to 0 and max. cappacity to 100% on Apollo and activated the battery with direct current

-Turned on the phone connected through iboot to trigger the battery message

-Installed the new battery with original BMS

Already watched hundreds of tutorials on the internet and followed every single step but nothing seems to work. Any ideas?
