Thanks to Heinz from https://tplinkforum.pl/
I made this changes (line 1639) in tools/firmware-utils/src/tplink-safeloader.c:
Before
if (strcasecmp(info->id, "ARCHER-C25-V1") == 0 ||
strcasecmp(info->id, "ARCHER-C59-V2") == 0 ||
After
if (strcasecmp(info->id, "ARCHER-C2-V3") == 0 ||
strcasecmp(info->id, "ARCHER-C25-V1") == 0 ||
strcasecmp(info->id, "ARCHER-C59-V2") == 0 ||
This works
