Any updates?

Or I have to take JTAG and restore my router on my own?

If so - please fix documentation: "you do it on your own riski - simply download this, flash via web, and enjoy new cool features " must read as "we don't know what we are talking about, we suggest random things which wll brick your router..." or "simply download this binary and use web-interface to flash your router, and you'll get a nice red brick..."

same here, upgraded the firmware from the zynos webui, and it is now a brick. sending it back to zyxel, their support is kind enough to jtag it for me.
btw mine was a p-334wt.
"we don't know what we are talking about, we suggest random things which wll brick your router..." - i must agree. something is fucked with this particular image and it hasn't been fixed! there's nothing one can do wrong with the webui update method, there's nothing particular to look out for, nothing mentioned on openwrt, etc, so it seems like a fairly simple and fail safe method - but it bricks your router and no one seems to care. :(
this was my first try with openwrt and the last one too. thanks guys.

Thanks for warning, I almost started planning of flashing my Zyxel Prestige 334 (vanilla?), but after reading this I'm not even considering it anymore.

My story: yesterday I've uploaded the latest kamikaze onto my P-334WT. After rebooting I thought 'I have a nice brick'. But actually not... After uploading the Kamikaze, the WAN port works as a LAN port, the other interfaces are down.
I connected a laptop to the WAN port and... I could access the web interface at

It seems to be working, except the LEDs (but the PWR) and the wifi are not operate
and I can't install anything by the opkg.
