Part Number: BQ78350

hello：

My client want to know how to remove the lock completely. He wants to write register, but it was locked immediately after unlocking. There's no time to write to the register, so how can I get rid of this lock completely

    Hi Jimmy,

    After the device is Sealed, it will always power up in Sealed mode. You need to send the UNSEAL and UNSEAL_FULL_ACCESS commands to be able to write to the registers.

    You might suggest loading the default firmware to the device after sending the command to unseal. This way the device will not boot up as Sealed.

    Best regards,

    Matt
