I’m trying to update my GT-98 Pro from stock ASUS fw (3.0.0.6.102_37038) to Merlin fw (3.0.0.6.102.3) but I’m getting a firmware not supported and update is unsuccessful message.
3006.102.3 (11-Jan-2025)
- NOTE: If flashing on top of Asus stock firmware 3006.102_37000
or greater, then you first need to enable downgrade
capabilities before flashing Asuswrt-Merlin on top
of it. Connect Over SSH, and run the following command:
nvram set DOWNGRADE_CHECK_PASS=1
After that, you can upload Asuswrt-Merlin through
the webui like any regular firmware upgrade.
This is only required when flashing Asuswrt-Merlin
for the first time.
BTW, those instructions are also in the README-merlin.txt file included in the archive, as well as on the Installation wiki page, which would be more intuitive for a first time installer than the Changelog.
