Revive bricked wndr3700

Post by nickowl »

Hello,
I've bricked my WNDS3700 yesterday, when trying to update to the latest version (file: gargoyle_1.12.0-ar71xx-generic-wndr3700-squashfs-sysupgrade.bin).
I started the upgrade using wired connection, and after ~20 mins of unsuccessful connectivity I have restarted it.
Now the router is accessible only with ssh, but no web interface is available.
Looking around, I found the "do _upgrade .sh" script (without the spaces), but when I was trying to follow the actions inside, it appeared, that the file "/usr/bin/bin2trx" tool is missing.
Please advise if there is a way to revive the router from this condition.
Thanks in advance for your help.
BRgds.

What version of the wndr3700?
What previous version of Gargoyle were you on?
Did you preserve settings?

You don't need bin2trx.

Ultimately, failsafe reset is probably the fastest way out.

Hello,

No version is mentioned in the router itself.
The previous version was 1.6.
I did preserver the settings, and I also did a backup before starting the update.
Could you advise (or mention a procedure) how to do failsafe reset.
Brgds.

Preserving settings is what has caused you trouble. It is specifically advised against when jumping such large version gaps, and particularly over certain versions with known incompatibilities.

If you still can SSH into your router, then you should be able to perform the below without entering failsafe first.

Code: Select all

firstboot -y
If that is successful, you can then

Code: Select all

reboot
If you need to use failsafe, you can put your router into failsafe as per here:

Note that as you are now on 1.12, you will need to use SSH instead of telnet.
