Hello,
I have two Wanwaytech S20 Pro with German Lidl-Connect Prepaid cards, that worked like a charm with traccar till above date.
First they did not sent any data to my own traccar server and then they do not answer to my SMS.
I soldered a RS232 to USB to the internal com port TXD1/RXD1 and this is the log:
enter factory test timeout ...

It seems that they did somehow a firmware update, as the firmware date is new (APR 15 2026).
Now the device seems bricked. The only thing still working ist the SOS Button that sends a position SMS to my smartphone.
Has anyone the same issue? Is there a solution?
Thank you.

Hi, it seems that I have this same issue, and a lot of other users are trying to find the reason what is going on. I was checking sim cards, sms commands, nothing is working, ~18 days ago device just stopped reporting positions, since this time nothing. So I also check serial port, and
^boot.rom'v'!\n^boot.rom'v'!\nRDY

Right now, it is time for warranty claims or charge back
