I did.

This saved my bacon.

If you don't have TFTP installed on your computer, try this.

I pushed the recommended firmware V2.5.2.20, took just seconds, and what a sign of relief!

Don't know if this fixes it all, but it saved me!!
Thanks for this, I knew I was forgetting an important section at the end of the OP and this would be it (link to netgear unbricking instructions). I've updated the OP with the links provided :)

This sounds like possibly bad flash or other faulty hardware unfortunately :(

The only option available in the GUI is setting up the stock Netgear OpenVPN server. OVPN and WireGuard 'client' config would be done via SSH in Voxel at the command line.

I need to change the IMEI back and I am getting an error after each magic command. Is there a way to reopen or revert back to the IMEI the device came with? I am able to perform other commands, do not understand why not allowing the command?? I have tried the factory reset without success.
If you are on the A06 modem firmware then you should not have to mess with +QPRTPARA=1; it is a sensitive setting for NVRAM that really shouldn't be touched if at all possible. If a factory reset has not helped then you may need to run a +QPRTPARA=3 which will factory reset the modem but be sure to follow it up with +QPRTPARA=1 else settings will not save properly to NVRAM after the next power cycle. Do NOT use +QPRTPARA=3 as it is very hard on the flash memory (lots of writes) and will decrease the longevity of the flash on the modem.

The DNS settings on the web interface in 'Advanced' -> 'Setup' -> 'Internet Setup' -> 'Internet' are ignored (at least in V9.2.5.2.30SF-HW).
For custom DNS it is recommended to use Stubby or DNSCrypt. The config for those is covered in the Voxel QuickStart.txt. For full instructions refer to the Stubby and DNSCrypt documentation.

I created a script that runs at startup and continues to overwrite /tmp/resolv.conf every minute.

Hopefully someone else has a better solution than this or can foresee problems with this one.

/mnt/circle/overlay/etc/rc.local

Code: Select all

/mnt/circle/overlay/opt/scripts/fixdns.sh > /dev/null 2>&1 &
exit 0
/mnt/circle/overlay/opt/scripts/fixdns.sh

Code: Select all

while true;
do
sleep 60
/bin/cp /mnt/circle/mods/resolv.conf /tmp/resolv.conf
done
Yes, this is one way to use your custom DNS. Since '/tmp' lives in memory you shouldn't have to worry about wearing out the router flash.

Maybe a better solution for custom DNS would be to simply overwrite the link at /etc/resolv.conf using the circle overlay at /mnt/circle/overlay/etc/resolv.conf

Would that work?

Not if another netgear service decides to overwrite or refresh it.

I noticed the latest Voxel firmware for the LBR20 from May 6 has this change:

9.2.5.2.31SF-HW:
5. Upgrade 'dnsmasq' package from the stock Orbi RBK50 firmware V2.7.4.24.

Any chance this will fix the custom DNS issue?
Can I just install the latest Voxel firmware over the last Voxel firmware? Would I lose my settings or scripts?

This is just maintenance/bug fix release of dnsmasq. Custom DNS it's still recommended to setup something yourself that overwrites '/etc/resolv.conf' or use the officially supported Stubby/DNSCrypt solutions offered by Voxel natively.

Yes, you can just install the latest update, it should not remove any settings/scripts.
