HiLo3G-D850 Bricked

I have had a couple modem modules fail during firmware update and they are no longer recognized by the developer kit board. No USB ports are found on the PC when the DevKit is powered on.

How can I fix these units? Is there a JTAG method to replacing the firmware files?

What version of downloader should I be using on these modules?

Hi,

You can contact you distributor and send back the module
