I have been using the SL8080T on the Sierra Wireless SL series development board. Attempts to make an HTTP connection were working, but buggy. The firmware version was 7.50xxx, so I wanted to update the firmware to 7.52xxx. The updates were found on the “Firmware package 7.52” page. I downloaded “Clear Terminal” version 2.0.0.4 and followed the instructions. My attempt to load “SIERRA\_OAT\_FW\_752\_68\_FULL\_sl808x.dwl” started (using Xmodem), but didn’t complete as described in other posts. The bootloader “SIERRA\_BOOT\_S4.1.0.13\_SL808x.dwl” seemed like it might need an update, so I sent it using the Xmodem on Clear Terminal. Now the SL8080T is in a state where I can’t use it properly. Commands are no longer echoed, only OK responses are sent. It won’t respond properly to AD+WDWL (it just replies OK). ATI3 gives the following: Sierra Wireless, Incorporated SL8080T APP3 OK All other commands just result in OK responses, so I can’t use the module and I don’t know how to make it operational again. Any help would be much appreciated. ---

This problem was solved with help from the rep using an updater over USB to get to to V7.52.0xxx.
