Well shooting my shot here since no else had this problem online and tech support still hasn't replied to my request in 4 days now. Anyways I was trying to update my system, an ancel fx2000, continued to "check for new version" and boom a power failure because of a downed power line somewhere. I go to boot it and originally got a message relating to "DOWNLOAD.BIN" or something similar. I was and still able to access the contents of the SD card via my laptop's SD card reader and deleted, not before copying over to my desktop, both Download.bin and ex_download.bin to see if that fixes. It got rid of the original message but now displays "Failed to verify EX_DOWNLOAD.BIN." Anyone have a solution on what to remove from the contents of the SD card or even a way to just get a fresh copy of it's contents in case I need to reformat it? I'm grasping at straws here and appreciate any help.

TLDR: Struggling with an Ancel FX2000 after a power failure during an update. I deleted (still have a copy) "Download.bin" and "ex_download.bin," which resolved one error but caused a new one: "Failed to verify EX_DOWNLOAD.BIN." I need help fixing the SD card or obtaining a fresh copy of its contents since I haven't received a tech support response.

Update in case you're in a similar situation: SD card ended up dead, brought a new one for 6$, reformatted it to fat and ran the upgrade software, BOOM
