Update error #[13-93]

Trying to update my “n1ha” to 0.85.2 (same with 0.85.2-RC). With both qFlipper and ios app - same result.
It fails with 13-93 error, and then it shows 0.85.2 FW version, but crashes upon Mfkey32 app launch.

  1. How can i debug update error on flipper side?
  2. Any ideas how to fix it?

thanks!
