Error 15 means communication error while checking if the chip is sealed or not. Also, Read Chip Info in your case does not return any information.

You can try this:

- Clear Intelligent Log

- New Reset -> Read SBS -> Next -> Select BQ304XX -> Next

- Read Chip Info

- Unseal

- Read Chip Info

Paste here the Intelligent Log.

For some reason, you lose communication when you try to Unseal and Clear errors. To make sure you have communication stable, before executing Unseal command you can read again SBS, just press Read SBS.
