Hello,
Thank you for your query.
FMB0YX and FMB9YX devices with firmware 01.00.32, 01.00.22 or older versions, can be updated directly to 01.03.13 by using firmware updater.
I have uploaded the firmware updater with firmware:
https://we.tl/t-7RxabkDbIR
Open updater>refresh>select com port>update.
When 01.03.13 version will be installed you can replace firmware file in firmware updater folder and update it to the latest version.
Best Regards,
Teltonika Support.
