Recently Coldcard/Coinkite released the latest firmware upgrade for the MK4 wallet

For Mk4 (new!): 2023-02-27T2105-v5.1.1-mk4-coldcard.dfu released Feb 27, 2023.

basically the issue is after you successfully downloaded the latest firmware into the microSD but when trying to do the upgrade from the MK4 wallet, it's not picking up the .dfu file which normally it should. Anyone has this issue and got it fixed? thanks
