Hi! I’m trying to update my modem HL7802/HL7800 modems with the last firmware available on source.sierrawireless web site. The problem that I’m dealing here is about the windows driver. When I connect the mangoh Red to the computer using a USB cable, the computer doesn’t identify the modem. ![image](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/0/0c827b992d5017182ba4051669cc8e4862315ec7.jpeg) ![image](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/0/012cb584637e415b54a261026b0edcdf1560a6bf.jpeg) I’m connecting the USB cable into the CF3 and appears this device in my desktop: ![image](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/6/68fc63029ef30e199188915dd9b28753ce563c4a.png) Well, where I can download this windows driver? I didn’t found it on source.sierrawireless portal… ---

Hi Donald, If I connect the USB cable into the Console USB port, my PC loads the correct driver: FTDI VCOM port. The up USB connector is connected directly to the modem USB port: ![image](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/d/d86a185907473d55ca883213027130ff8726bbe9.png) Or it is possible to use the console port to perform modem update? ---

Hi rafael.dias, Yes, You can use the console port to perform modem updates. ---

I connected the usb cable into the “console” port and I have access to the Legato terminal. ```auto U-Boot 2012.10 (Oct 30 2019 - 00:55:55) Board: ALT1250 Ver: 0.32-TG-D0 (PMP CPU Speed 120 MHz) DRAM: 2.5 MiB Now running in RAM - U-Boot at: 90294000 Boot mode 2 Flash Manufacturer/Device ID is: 0x20bb18 Enable QUAD mode Flash: 16 MiB *** Warning - Merge environment, using default environment map import OK USB CTRL has been successfully initialized!

😆 I tried one using the firmware upgrade tool [HL7800.4.6.8.0.exe](https://source.sierrawireless.com/-/media/support_downloads/airprime/software/hl7800/4,-d-,6,-d-,8,-d-,0/exe/hl7800,-d-,4,-d-,6,-d-,8,-d-,0.ashx) . The firmware update started but at some point (I was not taking care about the process) occurred a exception and the firmware update tool restarted. Now the console terminal is doing nothing… ```auto U-Boot 2012.10 (Feb 13 2021 - 02:53:53) Board: ALT1250 Ver: 0.32-TG-D0 (PMP CPU Speed 120 MHz) DRAM: 2.5 MiB Now running in RAM - U-Boot at: 902a4000 Boot mode 2 Flash Manufacturer/Device ID is: 0x20bb18 Enable QUAD mode Flash: 16 MiB *** Warning - Merge environment, using default environment map import OK In: serial Out: serial Err: serial Configuring Flash Write Protection (offset 0x1e00) new_ce_val = 0x3a0001e8 Hit '\r' or '\e' key to stop autoboot: 0 Version: 2.0 Nothing to upgrade... image part OK ``` I’m trying to sent anything thought the terminal but the modem does not answer anything. ---

Hi rafael.dias, Please refer to the below links for more information. > [@HL7800 debug uart console toast after fw](https://forum.sierrawireless.com/t/hl7800-debug-uart-console-toast-after-fw/20756): > > I just updated a HL7800-M module to latest firmware 4.4.6.0 (from an ancient 1.7.5) without issue. but now the debug console which used to work fine is no longer responsive.
