Looking for SENC file to upgrade from original device bq20z75-v160 to newest available firmware (AFAIK v181 equivalent to what is used on the orderable device bq20z75-v180)

Other Parts Discussed in Thread: BQ20Z75-V160, BQ20Z75-V180

Hi, Can someone please tell me where to get the following SENC firmware as below? I'm looking for the .SENC file to upgrade an original ordered device bq20z75-v160 running factory stock firmware (v160 I suppose) upgrading to the newest available z75 firmware (AFAIK v181 firmware is actually equivalent to what is shipped on the orderable device bq20z75-v180 per SLUA578) "The bq20z75-V180 contains a firmware upgrade to enable several feature additions and corrections. The device contains firmware V181 even though the device orderable is v180. New orderable part numbers have been released to support this firmware upgraded device. • bq20z75DBT-V180 • bq20z75DBTR-V180" Thanks!
