EHWIC-4G-LTE-G upgrade software


Hi there,


I'm looking to upgrade the EHWIC-4G-LTE-G SKU MC7710 but i cant find the right firmware, or do I? I feel like I'm running arround in circles:

Here I find the upgrade link: Cisco Firmware Upgrade Guide for Cellular Modems:

There I cannot find the EHWIC-4G-LTE-G SKU MC7710. So i looked at Cisco site self but it doesn't list anything with the Serial number. 


The reason I'm looking at upgrading the firmware is because I get errors on this modem after upgradeing to 157-3.M5.


So can I use one of the firmware's from the first site? Is there a difference between EHWIC-4G-LTE-G and the EHWIC-4G-LTE-GB? What do i need to pay attention to when looking for software. Does the MC7710 mean something or not? The EHWIC-4G-LTE-G is still sold, so I must be doing something wrong, I just can't figure out what...


Some help would be appreciated.


Thanks in advance


BTW; Associated products also doesn't return e query for EHWIC-4G-LTE-G or MC7710...

Hi I havent upgraded the specific wic before but this doc seems to contain information on it and how to do it , may help ,its loks like sierra software not cisco though What i think is if you upgrade the whole device is the sierra part should upgrade too as the files will be contained in the IOS have you tried that ? Go to the latest Cisco image for the router upgrade and check is the ewic upgraded too see Philips post MC7710 Manual Modem Firmware Upgrade: Example MC7710 Manual Modem Firmware Upgrade: Example Device# microcode reload cellular 0 0 modem-provision flash:MC7710_Global_03.05.19.04_00.cwe Reload microcode?
