Has anyone used the Firmware package 7.54.0.A1 for SL808xT/BT package? I noticed that the digital signature for Firmware package 7.54.0.A1 for SL808xT/BT, R7.54.0.A1.201603171313.SL808xA\_22\_1.exe digital signature has been revoked by Sierra Wireless. Is this firmware package infected by malware? I downloaded it 5 years ago. I checked Sierra Wireless website, the file online is exactly the same one as my copy - [https://source.sierrawireless.com/resources/airprime/software/firmware-package-7,-d-,54,-d-,0,-d-,a1-for-sl808xt\_bt/#sthash.Ud0SzXEg.T29uqfb4.dpbs](https://source.sierrawireless.com/resources/airprime/software/firmware-package-7,-d-,54,-d-,0,-d-,a1-for-sl808xt_bt/#sthash.Ud0SzXEg.T29uqfb4.dpbs) Has anyone used this package? Thanks! ☹ ---

it has been expired: ![image](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/d/d3e1e6fe5089b75e480b0fe771f4105ac37a9187.png) But I believe you can still use the exe, right? ---

The expired certificate isn’t an issue. The issue is the certificate has been explicitly revoked. Here’s another firmware package which is older but has valid certificate. ![Firmware-cert - Copy](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/7/7dff092562bc7b9f7b5c842c72f91ea0de681e24.jpeg) ---

if you don’t trust this exe, you can download the dwl file and use AT+WDWL to download to the module ---

Have you used this package? I just want to confirm if this exe package (the original one since 2016/2017) has been used successfully. ---

What do you mean by (the original one since 2016/2017) ? R7.54.0.A1.201603171313.SL808xA\_22\_1.exe? I don’t have SL8 module now, have you tried that exe in SOURCE page? ---

Actually, the one on the website is the original one. I downloaded mine 5 years ago, the file size is the same as the one on the website. ![Original - Copy](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/8/8948f6902c27be874162ac8f83340e1ec2be3419.jpeg)
