Aqeel,

Every bq device you mentioned above is custom, protected by an NDA. The only way to get unseal keys is to get in contact with the pack manufacturer.

Hi, "TI Employee",

I have battery pack with bq2084 chip. I unsealed it with 2084-7a43 codes. It worked. 0x00f6-f9 wrote to 00. I checked it with be2works demo.

I tried to reading and writing flash with command 50,51,52, reading has worked, writing didn't.

I know 0xf6-f9 are 00, I tried to writing in this flash area. (data 1111,1122,1234). It didn't worked.

Before last time I send to 0x00-->062b. Nothing happened.

Last time I send to 0x00-->062b and 0x00-->1111. The chip did sealed.

OK, I unsealed it. I thought. But I can't unsealed the 2084 !

My question are : in this case what is the password? 0000,1111,1234, ?

How I can unsealed this battery? Old password doesn't work.

How I can access to writing flash?

Thank You for Your answer
