Got it fixed after a hell lot of research

Hi all,

Finally after searching a lot in net, flashed the bluetooth partition with the img file available in the following site ( Phenotypically ) -> mirrors[dot]lolinet[dot]com[slash]firmware[slash]moto[slash]chef[slash]official[slash]RETIN

The root cause for getting the partition formatted is gettiing the following error, to solve it I tried to restore bluetooth partition and it resulted currupt. Hope it may help somebody who will be get the same issue and stumble upon this page.

I was getting "Update Failed" error in Moto updator. While checking for the logs via adb observed the following error :

Since Moto One Power is having A/B Partition and seemless update support, It looks like the incremental security update was checking for the checksum of the corresponding partition before applying the incremental update. To fix this I flashed the bluetooth and other failing partitions with the apropriate images available in the above shared link.
