Can't update TL-WR820N V2 firmware
I took newer firmware TL-WR820N(RU)_V2_1.12.0 Build 240329 from there:
https://www.tp-link.com/ru/support/download/tl-wr820n/v2/#Firmware
When trying to install it im getting: Failed to upgrade the firmware. Please check the configuration file and try again.
I tried installing from different browsers and devices
Also i thought about downloading the firmware from the Ukrainian version of the tplink site, but for my router they are not there:

How can I install the 1.12.0 firmware build?
