February security updates are here for the BlackBerry DTEK50 and DTEK6019
Once you receive notification that the update is available on your DTEK50 or DTEK60, make sure that you are connected to a Wi-Fi network. Also, make sure that your battery is fully charged before continuing on with the updating process. The updates are being sent OTA and are weighing in at 100+MB, hinting that there are bug fixes and other improvements included. The new software version appears to be AAU660. Right now, it seems as though the unlocked versions of the two models are first in line to receive the update.
A previous attempt made back in December to update the DTEK50 and the DTEK60 failed, according to the BlackBerry support page. "In some cases the available update will not install. A message Waiting for Wi-Fi or Verification Failed will be presented to the user on the update screen." Hopefully, there will be no such issues with the new files being sent out. If you do receive the "Waiting for Wi-Fi" or "Verification Failed" messages, the BlackBerry support page lists a workaround that you might want to try.
