Nokia Lumia 635 RM-978 Test Mode PackageHandling of dynamic Test Mode Software files in Care Suite Product Support Tool and Testing & Tuning Tool: When needed, Dynamic Test Mode Software files will be downloaded to PC from Nokia FirmwareRepository (FiRe), and uploaded to device RAM so that the above mentioned functions can be run. If the required Dynamic Test Mode Software file already exists on PC locally, and version check accepts it to be used with device software, it will be uploaded to device RAM and run from there when TEST mode is needed. File will be uploaded to device RAM after each reboot, so for example during variant change this can happen more than once. If version matcing device software is not found from PC locally, or the version does not match with device software, new file download from FiRe will happen.
