Recommended method to trigger programming without access to prog button, with ehex on locked T4.1

[strud]

I have a product design that uses a locked T4.1 and no easy access to the prog pushbutton.

Therefore I am looking for a method to trigger the bootloader and programming with an ehex via the usb port.

Current idea is to use TyCommander to trigger the programming which Teensy loader.

It seems TyCommander does not currently support ehex, hence are there any other suggestions aside from what I have above?

I could provide a remote switch hooked up to the prog input I guess.....

User @Dogbone06 has successfully done EHEX updates on locked T4.x with FlasherX, which does not require button access. If you search his posts you will find it.

I've even gone so far as to put it into a real product. Scary moment, but it works well.
