^SYSSTART DOWNLOAD MODE | Telit Cinterion IoT Developer Community

I have a PLS8-E module that is acting strange.

When I connect it it gets enumerated and I get all USB serials and such. But none of them is replying to AT-comands. But I can download new firmware on one of the ports if I use a firmware tool in recovery mode, (one that skips AT^SFDL). When doing this the module responds whit ANSWER_OK, (0x01 byte), to all uploaded data. After download the module restarts but it does not change its behaviour.

I have also connected to the ASC0-port. And there I always get an "^SYSSTART DOWNLOAD MODE" when the module starts. I can also upload to this port in recovery mode, but the problem persists here too.

So is there anything more I can do to try to recover the module?
