Any updates on this?
An user reported to us this same issue with the latest 2021 version of
the C7v5-US tp-link firmware [as available in Brazil].
Install was possible only through tftp: the tp-link stock firmware web
page would refuse the factory image.

Hi,
Currently it's not possible to flash factory images on devices shipped with
vendor firmware versions 1.1.0 Build 20201120 rel. 50406 (published
2020-12-22):
Will this prevent flashing back vendor firmware via TFTP or is a different
comparison used there?
nope, it seems like U-Boot has different kind of checks. For example my
testing unit has following U-Boot:
U-Boot 1.1.4-gbec22107-dirty (Nov 18 2020 - 18:19:12)
and flashing from OpenWrt back to stock with latest factory vendor image
c7v5_us-up-ver1-1-2-P1[20210125-rel37999]_2021-01-25_10.33.55.bin
works as expected:
Firmware downloaded... filesize = 0xeeae77 fileaddr = 0x80060000.
Firmware Recovery file length : 15642231
Firmware process id 2.
handle_fw_cloud 146
Image verify OK!
Firmware file Verify ok!
