Tool/software:
We were trying to Full access the device by using Security Keys command along with the checksum, but the device couldn't be unsealed:
Following is the steps followed:
1. The device is sealed using 0x0030 command
2. The Full access key 1 sent 0x1404 to the address 0x0035 along with check sum 0x60 0xB2 0x06
3. The Full access key 2 sent 0x3672 to the address 0x0035 along with check sum 0x60 0x22 0x06
Checked in the battery status device still it was sealed only.
