Elite Controller Update failed now won’t work at all

[Adampark]

Hi,  I purchased a batch of elite controllers to repair, was all going fine until I plugged the controller in via the usb lead and it said update required halfway through the update it failed now the controller won’t sync just flashes, went on too the next controller done exactly the same ended up doing the same thing  too 4 elite controllers was all working fine before the update crashed   
I was wondering can I update the software manually or something or is there anything I can do.

Any information would be muchly appreciated!

What happens when you try to update it again?

If you're using W10 there, you can also try updating the FW with the PC using the Xbox Accessories App.

Exactly the same problem I have, happened to me last week and I can't update through the XBox One nor XBox Accessories app.
