Rutm52 update to RUTM_R_00.07.13.4

Hello,
I receive the RUTM52, with the version RUTM_R_00.07.11.2 and want to update to the RUTM_R_00.07.13.4 as proposed by the WebUI.
First try, I push the Update button with the default values, I receive an error as the file was not ok, so I download the file from the FW & SDK Downloads - Teltonika Networks Wiki page, and when I try to update I receive a message that the file was corrupted.
I reset the router to the factory default, and same thing.
I don’t know what to do!

Good afternoon,

Please try to download the firmware file from : https://wiki.teltonika-networks.com/view/RUTM52_Firmware_Downloads
Latest FW

Then try to upload that file when you are upgrading the device’s firmware via WEBUI.

In regards to the error when you try to update the firmware automatically, do you have internet connection when you do the upgrade?

Lastly, you can try flashing device’s firmware via bootloader method. Instructions : https://wiki.teltonika-networks.com/view/RUTM52_Device_Recovery_Options#Bootloader_menu

I wasn’t at home , I try the automatic update today, and all is ok now!
I don’t know what was happen before
Thanks
