Dm verity verification failed DRK Galaxy S7 Edge G930 G935 Samsung S6, edge

Hello
All android by default have dm-verity check on system modification detection to break things like 

  1. Root
  2. Kernel modification
  3. Malware protection
  4. Customization
  5. Android payment system protection
  6. NFC payment system protection.

  • By defaults DM-VERITY enabled on most android 5.1.x and newer.
  • Samsung adopted dm-verity and used Device Root Key(DRK) to make DM-Verity Sign.
  • Due to DRK is already available on most models (at factory programming time ) of samsung & all platform so it was easy to implement dm-verity which is default enable on all 5.1.x and newer, samsung did not loos time and used same keys for dm-verity.
  • Old time DRK was only used for REACTIVATION session challenge calculation. (even if its not used all device have drk long before dm-verity come,older )
  • DRK provide keys for dm-verity to make encryption enable and full check on system or user data encryption.
  • GCPro can fix your device DRK to close one which factory have in technically its fix DM-Verity too.
  • GCPro fix issue for ever its not temp repair or bypass or skip.

Movie Maker was officially removed for download on January 10, 2017. Unlike other Windows Essentials apps, Movie Maker has not yet been replaced or succeeded by anything else. Microsoft stated a new version in the Windows Store would be available "soon". However, once they pulled the download on January 10, they removed references to the promised new edition. With no official first-party download and no confirmation of a new version, Movie Maker has effectively been discontinued.
Movie Maker is included in the Windows Essentials 2012 program suite so make sure that you update your framework too.
