I have two multiple year old RV50x that I have to put on a new cellular plan with new SIM cards, but first need to do firmware updates on them. Can the firmware updates be fully done locally with AceManager web interface? Are there specific firmware versions I have to step up through?

Hi @Dada,

1. What ALEOS version is your RV50X running? What is the radio module firmware version?  
You can check this information using the web ACEmanager under the Status \> About tab.

2. Please refer to the RV50X Firmware Packages at the following link: [https://source.sierrawireless.com/resources/airlink/software\_downloads/rv50/rv50x-firmware-list/#st…](https://source.sierrawireless.com/resources/airlink/software_downloads/rv50/rv50x-firmware-list/#sthash.phzSkGhk.dpbs)  
Warning: Upgrading from ALEOS 4.15.x and earlier releases to 4.18.1 is not directly supported.

3. Please refer to the section “Update the ALEOS Software and Radio Module Firmware” on pages 25–30 of the ALEOS 4.18.1 Software Configuration User Guide for AirLink RV50X to perform the firmware updates locally using the web ACEmanager: [source.sierrawireless.com/resources/airlink/software\_reference\_docs/airlink-rv-series—configuration-guide/](https://source.sierrawireless.com/resources/airlink/software_reference_docs/airlink-rv-series---configuration-guide/#sthash.wBAe2N33.dpbs)

Thanks,
