    I have an EDM-740 firmware version 7.10.000 in my Experimental. It was having a Datalog Error so I tried to upgrade its firmware to V7.47. Per the downloaded directions I transferred the .pkg file to the jump drive, but the Apploader (Nov 17, 2009) kept asking for a .sim extension file.
    Now the 740 unit will not start up, keeps starting to the Apploader asking for a .sim. On advice from an Avionics Tech, I've also tried to upload the 730/830 V3.52 with no luck. Of course JPI is closed for the pandemic, and I'm grounded until this is fixed.

    Can someone perhaps:
    1 - tell me what I'm doing wrong, a better way to either update, or how to return to my original version
    2 - provide an new or older .sim file so that I can upgrade to that

    I'd appreciate any feedback or assistance.
