I want to downgrade the firmware from WisGateOS_2.1.4_RAK to WisGateOS_1.2.3. In the administration I only can upload files with type RWI. But WisGateOS_1.2.3 is a BIN file.
How can I change the firmware with ssh directly?
I must downgrade, because I use a special packet forwarder from out LNS Loriot, which runs only with this early version of firmware.
Thanks in advance!
