TP-LINK Archer C50 V4

Hi all.
I'm Trying to install a OpenWRT FW on a TP-LINK Archer C50 v4.
I found at compatibilty of devices just a Snapshot avaliable for this version:
https://openwrt.org/toh/views/toh_fwdownload
https://downloads.openwrt.org/snapshots/targets/ramips/mt76x8/openwrt-ramips-mt76x8-tplink_c50-v4-squashfs-sysupgrade.bin

But when I try to install this snapshot the router show me the error: Erro Code: 4503
The uploaded file was not accepted by the device.

The TP-LINK Original FW is:
Firmware:
0.9.1 0.2 v0093.0 Build 180313 Rel.54477n(4252)

Hardware:
Archer C50 v4 00000002

Already tried to rename the file to TP-LINK name file, but it did not work.

Someone Know how to fix it?

Thanks in advance!!!!
