I am in trying to install the latest firmware version for the R412M iM0.10.00,A.02.14. using Easyflash but it is failing with error ‘Backup failed’ as described here:
Windows shows that the device driver for Qualcomm HS-USB Modem 90B2 is up to date but the windows device connect/disconnect sound plays every 3 or 4 seconds constantly when the USB is connected to the boards u-blox module.
I’ve repeated the steps many times. I still have M0.09.00,A.02.11 installed as Easyflash won’t progress beyond the backup.
Has anyone seen and overcome this problem?
