Fenvi upgrade to openwrt

I did as said here EDUP EP-RT2960 AX1800 - Strange OpenWRT router - #62 by The1plusguy.
From oem webui, i did a upgrade to 'x-wrt-25.04-b202505270146-ramips-mt7621-xwrt_wr1800k-ax-nand-initramfs-WR1800K-factory' but then nothing special did happen and now i cant access webui at 192.168.100.1 anymore.

@The1plusguy can you help me?

Does it give out IPs ?
Can you ssh to it ?

AP SSID work and give IP.
Gateway is 192.168.100.1 and give 192.168.100.146 as lan ip.
I tried to connect do 192.168.100.1:22 but was refused.

It's x-wrt, we have no idea how is supposed to work, ssh was only me guessing.

Did hard-reset and returned to work, model is WR1203S maybe is not a 1800t.
