Hi Vianney,

Hmmm, I’ve tried running the **2.27** installer, but I get message per red box below. Per message, if we reboot our HL7692, nothing seems to happen. Ditto if we don’t reboot. After a minute, we see the messages below the red-boxed. And then per the last message, the prompt closes after a further 5 seconds ☹

 ![x](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/8/813f70ad135c448bf687cf31d5640c29f1b1fc08.png)  
The HL7692 is connected to my PC on COM7, comspec 115200 N81. AT command communication works fine on COM7, using a terminal emulator.

I’ve tried the installer with the HL7692 freshly booted, after waiting the 13.2 seconds for it to boot. I’ve also tried the installer after issuing a few AT commands.

I’ve googled a bit, and found this post: [Dev kit HL8548-G firmware](https://forum.sierrawireless.com/t/dev-kit-hl8548-g-firmware/8175/9)

Taking the hint cue from that post, I typed %APPDATA% in my Windows Explorer, takes me to folder C:\Users\dking\AppData\Roaming\

I then created there, an `HL76xx_download.ini` file, containing:

```
[CommPort]
Port=COM7
ComBaud=115200

```

Per the [Dev kit HL8548-G firmware](https://forum.sierrawireless.com/t/dev-kit-hl8548-g-firmware/8175/9), noted that the ComBaud line might be ignored, and 115200 is used always.

Unfortunately, this guessed solution didn’t work. Ditto, if I tried instead filename _HL7692\_download.ini_

As mentioned, our HL7692 presently has **2.23** firmware, which is what it came with. FWIW, I tried the **2.23** installer. Same sorry story.

I’m presently out of ideas !

Best regards,

David
