I trying install OpenWrt on my router TP-LINK Archer A7 v5 (RU) with software version: 1.0.11 Build 20190810 rel.50990. I trying load openwrt-19.07.3-ath79-generic-tplink_archer-a7-v5-squashfs-factory.bin file from OEM GUI, but I got error "Invalid file type.".
Please specify how I can flash my router?
TFTP solution from this topic: TP-LINK Archer C7 v5 factory.bin won't load not working for me.
Or maybe any know how I can switch from DD-Wrt to Open-Wrt? I can flash DD-Wrt from OEM GUI.
Please note however that this page will refuse to install firmware uploaded with a long filename. To bypass this limitation, download the relevant factory-flash BIN-file and then rename the file to firmware.bin before uploading.
The header of a stock or "factory" image has one or more country codes. If the expected country code is not found in the firmware presented, both TFTP and stock firmware GUI will refuse to flash it.
Using mtd directly from dd-wrt CLI could work. There is a high risk of bricking when using mtd directly. Make backups of the bootloader and ART partitions. Also make sure you can TFTP recover to RU stock. Then use dd-wrt to mtd the sysupgrade (not factory) OpenWrt to the firmware partition.
If write to linux partition from dd-wrt I got this error:
Unlocking linux ...
flash : Could not unlock MTD device: linux
linux: No such file or directory
Writing from firmware_openwrt.bin to linux ... [w]

Router rebooting and not boot to OS. Light only one power indicator. TFTP working but not flash any image.
I can restore routrer after this manipulation only flashing raw image on mem with programmer.
