Important
 The Verify Signature option does not apply to recovery mode. It is not possible to
force an XT version 9.0 or higher to accept an unsigned package when in recovery
mode. See Known Issues, "Software Upgrade & Downgrade" section and the table
below.
Important
 The signed package version cannot be uploaded directly on an XT running a version
8.3.x or earlier by USB or XT Web interface or AT interface or iView. You need to use
a special unsigned package in this case. Ask Customer support to receive an
unsigned package.
