After Looking Some Forums, I found nothing about this device, However i am aware that the Archer A5 V5 and The Archer C50 V5 Are Identical (both have the MediaTek MT7628A) , And also have found that there is a fork for The Archer C50 V4 That works on the V5 Aswell, so that means then that i may be able to install the open wrt firmware on the A5 V5 One, i also found that i have to compile my own fork and not use the c50 V4 one or the C50 v5 one, so i am a little bit confused at following steps, i also know if i install open wrt i will not be able to revert to stock, i kindly request you a hand to be clear and be able to install open Wrt on it.
Archer A5v5 and C50v5 use exactly the same TPlink firmwares when I downloaded from TPlink USA website, and compared them at binary level. In fact, the firmware for the A5v5 is called 'C50v5*.bin'.
In any case, I uploaded TFTP openwrt 19.07.3 install image file called tp_recovery.bin for the A5v5 (and C50v5) to my dropbox folder for the C50v4 for testing.
The Debricking instructions in the C50 wiki, perhaps could be used on C50v5/A5v5, to install 'truncated' TPlink OEM firmware when renamed tp_recovery.bin ? https://openwrt.org/toh/tp-link/archer-c50
