Hello Neo,
In bqStudio you can just send the Unseal and Unseal Full Access commands by clicking the button in the "Commands" tab on the right side of your screen. Please send the unseal command before the unseal full access command.

Unseal Key is: wr 00 14 04
wr 00 72 36
The command data is reverse order on the right side of screen.
It's easy to confuse and misunderstand.

Hello Neo,
There is an example for how to Unseal the gauge and to enter Full Access in the BQ27220 Technical Reference Manual (see image below).
