Hello Teltonika Community and Support Team,

I am requesting urgent assistance with obtaining an older firmware file for my RUT525 WiMAX router.

**The Problem:**

My device lost all WiMAX functionality and modem drivers after I updated the firmware to the latest available version for the RUT5XX series: **RUT5XX_R_01.00.875**. The WiMAX section now displays “N/A” (I have attached a screenshot).

**The Solution Required:**

The router was working perfectly on the older version: **RUT5XX_R_01.00.819.bin**. Since this file is no longer available on the official downloads page, I need this specific file to perform a downgrade (firmware recovery) and restore WiMAX functionality.

**Device Specifications:**

* **Model:** RUT525

* **Product Code:** G30044

* **Hardware Rev:** 1.1

Could a Teltonika representative or a community member who has a copy of **RUT5XX_R_01.00.819.bin** please provide a secure download link?
