SHA2 Support for all ES405 MC659B MC45 Products - SPR 26392 Release Notes


This patch addresses SPR26392 – VPA – SHA2 Support for all ES405 MC659B MC45 products. As part of fix, Microsoft released a new AKU (build no. 29299) which contains the support for recognizing the SHA2 certificate through Cryptographic APIs (CAPIs).


1)  This issue is seen on all ES405 MC659B MC45 devices running WEHH6.5. SHA2 certificate is not recognized properly and installing any root SHA2 certificate gets installed in intermediate section rather than root section. Also there was an issue syncing emails from Microsoft exchange server.

2)  The latest OS hotfix image built with AKU35 solves the issue.
