MR2100-100EUS Firmware

hi, 
Like many people, my MR2100-100EUS is bricked following a firmware update.
I'm stuck on the startup screen with the NETGEAR logo.
I can display the "downloading software update" page.
the reset does nothing.
I'm desperately looking for firmware that I can manually load on this model.
can you tell me what to do to unbrick this hotspot?
regards
