Hello,

I have an old one of RUT900, with an Firmware 00.01...

I tried to install an new one, but it doesnt work.

So i found the Bootloader Update, but I have the Problem that the Update also doesnt work.

There is the Error Checksum, I tried it several times.

Thanks for your help

Hello,

You have tried to update bootloader itself: https://wiki.teltonika.lt/index.php?title=RUT9xx_Bootloader_Upgrade

or a firmware via bootloader menu: https://wiki.teltonika.lt/index.php?title=RUT9xx_Firmware_via_The_Bootloader_Menu

 by following wiki instructions ?
