Had a RUT240 stop responding, so did a bootloader reset.

Managed to get it working on the old firmware but as soon as I update, I can't login (spinning "loading" icon after entering username and password). Reverted back to old fw via bootloader procedure, updated to latest version and it does the same each time.

Is it faulty?

There could be a cache issue, could you try incognito mode to see if the issue still persists?

When you update to the newer FW, do you have the keep setting option disabled or enabled? I would recommend disabling it.

From which to which FW are you upgrading your device?

Same result in incognito mode.

I've reverted back to the original firmware using the bootloader. Serial number showing blank and MAC showing FFFFFFFFFF.

I can try the latest firmware version again, disabling the option

Updated firmware with the save settings option disabled - still just hangs after entering password.

All 5 signal LED's are blinking - not sure if that means anything

Hi - this still hasnt been fixed - how do I get Teltonika to remote connect and fix??
by anonymous
What is your time zone (GMT), what is the firmware version last installed in your device, when would you be available for a remote and could you send your AnyDesk address?

Please provide the above details in a private message.

Best regards,

Hello - timezone is GMT, firmware was updated to latest but believe the bootloader start may revert it to the factory default

Could you provide a serial of the device, which can be found on the router itself or its packaging? We would need to arrange a remote to restore it via Anydesk.
