[SOLVED] RB941-2nd bricked after package upgrade

[ludronupse]

Hi

Be extra careful with updating!

After update packages via luci and rebooting my device is... down.

Router: rb941-2nd

No any possibility to connect via ssh or telnet.

Hard reset won't work.
No ping.
Just some answer:
192.168.1.255 request Announcement USER1 (browser protocol)
192.168.1.255 name query NB (nbns protocol)
192.168.1.2 (source ip) ICMP Host unreachable.
224.0.0.252 (LLNM protocol) standard query 0x023d,0x050e,0x9d75
192.168.1.255 (NBNS protocol) NB ISATAP<00>

Method of hard reset: quick pressing reset button and long (10-20 sec). All ports 1(wan) and 2-4(lan).

Anyone know how to solve it?

Updating? Or upgrading packages?

[ludronupse]

packages via luci

[frollic]

that can be a bad thing, depending on what openwrt version you were running, and how/what you did.

[anon89577378]

Right...but did you update packages, or upgrade packages?

Big difference.

[ludronupse]

I don't remember exactly.. 19.07 may be

[anon89577378]

Still haven't answered the question on updating or upgrading packages...

Describe the steps you did in LuCI.

[ludronupse]

usually I use opkg update via ssh. At this time via luci... It wasn't upgrading OpenWrt firmware.

[frollic]

doesn't seem to matter though, since the device's dead ...

perhaps we should focus on the recovery ?

[ludronupse]

Yes, recovery will be great. I think it's alive. But no connection.

For future reference...

OK -

Not good -

@ludronupse

Update list -> Updates -> Upgrade... Reboot

That's why it bricked.

See the above screen shots.

Try to restore the original firmware using an older version of netinstall.
