Write error code, cause code, and retry count into last_install. So we can have more information about the reason of a failed OTA. Example of new last_install: @/cache/recovery/block.map package name 0 install result retry: 1 retry count (new) error: 30 error code (new) cause: 12 error cause (new) Details in: go/android-ota-errorcode Bug: 28471955 Change-Id: I00e7153c821e7355c1be81a86c7f228108f3dc37
