The uploaded image file does not contain a supported format

[ORo]

I get the error when updating the firmware to RUT2_R_00.07.06.14_WEBUI.bin with one of our rut240 RUT2_R_00.07.02.4:
Kernel version
5.4.147
Internal modem firmware version
SLM750-V_4.0.12_EQ101

The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform.

Now I have found a solution with a script:
https://community.teltonika.lt/t/rut240-unable-to-update-firmware-getting-error-the-uploaded-image-file-does-not-contain-a-supported-format/7003

I executed the script and got the following output:

root@Teltonika-RUT240:~# chmod +x wdt.sh && ./wdt.sh &
root@Teltonika-RUT240:~# {
“status”: “running”,
“timeout”: 21,
“frequency”: 5,
“magicclose”: true
}
{
“status”: “offline”,
“timeout”: 21,
“frequency”: 5,
“magicclose”: true
}

When I try to update the firmware again, I get the same error.

Hi ORo,

Welcome to Teltonika Networks Community!

If you upgrade it to 7.6.13, was it successful? I’m not sure if this has already been tried but can you do bootloader recovery and from there upload the firmware file? Simply follow the steps shown here.

Let me know if this helps.

Hello,
thank you very much for your answer!
Unfortunately it’s not that simple - because the device is installed outside in rough terrain. I only have remote access. I will be replacing it in the next few weeks.
