CPE510 V.3.20 Firmware 2.2.1 build 20200612 Rel. 38059 (5553)

In the configuration tab is not the option Country or Region; then is not possible select the "test mode"; in my case these will be installed in Venezuela here we have not restrictions about frequencies uses or bands. I was try actualize the device to firmware 2.2.2 Build 20201111 (UN), I was download it from the TP-LINK WEB but the Country or Region is not in device configuration page. It bug causes many another several errors and problems in the configuration process, example: if one setting the "nano station"  how client with channel static 153 / 5765MHz, SNR 24, signal/noise -66/-90 dBm, and right all security parameters ; the radio link can not establish.

I was explore the CPE510 V.3.20 firmware 2.2.2 Build 20201111 (UN) file system Whit ssh app; in the path /web/modules/wireless/view/ the file basic_settings.html are comment the lines 43 to 48 where are the configuration instructions but the file system is read only.

I have another CPE510 V3.20 Firmware 2.2.1 Build 20200612 Rel. 38059 (0000), in it device the "test mode" is aviable; It device work fine and I have not problems with it.

¿It's possible download or transfer the file Firmware 2.2.1 Build 20200612 Rel. 38059 (0000) from one to the another device?

¿What I can do?
