I am unable to restore a backup file I made on RUT240 running on 07.01.4 after updating the router to the latest firmware 07.02.5:
"The selected backup file is not compatible with this device, please choose another file."
As frustrating as the situation is, I decided to revert to the 07.01.4 but the router won't even let me revert back to the older firmware saying:
"Firmware validation failed due to invalid firmware image. Make sure your firmware is obtained from official sources."
although the firmware was downloaded from the official site https://wiki.teltonika-networks.com/view/RUT240_Firmware_Downloads
Is there a way to fix this issue, I am wasting a lot of time and money because of this problem and on the verge of stop considering Teltonika for future projects.
