IoT Modules MC/EM Series

Hi,

I have Windows 10 running it keeps telling me Firmware Download Failed for mc7304 :open_mouth:
I need version 05.05.26.02 running to avoid the 350 error bug.
[url]https://forum.sierrawireless.com/t/cms-error-350-when-sending-sms/7927/2]

Output

FDT version 5.0.1501.1
Checking modem mode ...
Disabling selective suspend ...
Switching device boot & hold mode

Firmware ware download failed
Primary error code : 4 - Device is removed
Secondary error code: 0 - Not applicable
Device error code: 0x0 - Succesful
Total time elapsed: 64781 ms.

Then it removes the device from the Windows device manager.

Hi Stefan,

How about the latest FW updater?
http://source.sierrawireless.com/resources/airprime/software/airprime-mc73xx-fw-package-build-4399/

The mentioned issue was fixed in 5.5.2x.0, latest FW should include the same and with even more improvement/carrier approval.

Also, may I ask the original FW version and carrier used when you face 350 error?
Thx

Thanks for you response Lotam. Yes, i used the lastes FW Updates with no effect.
I have the 0.16(2014) firmware loaded on my MC7304.

Mabye i should try to use a different OS than Windows 10?

I’ve found the problem.
The firmware tool only works in Windows 8.1 and not in Windows 10.
I solved the problem by temporary switching to Windows 8.1 and upgrading the firmware.
My error 350 is gone now to :smiley:
