I found a work around:
So if you have the T100-E with the solid Green light always on, what you need to do is to follow this process on the “Bricked Device” section. But you may find an issue when you try to run this command adafruit-nrfutil --verbose dfu serial --package t1000_e_bootloader-0.9.1-5-g488711a_s140_7.3.0.zip -p /dev/tty.SLAB_USBtoUART -b 115200 --singlebank --touch 1200 , saying that the device is busy and you will have an error associated with it.
In this case what you need to do is to press the button on the device disconnect and connect the power, release the button and run straight away the command line again and that will fix the problem. Once that is done, you need to flash it with the last firmware and done
