Hi!
I think i bricked my WR-941ND ver 3.6.
I was running dd-wrt for about a year (running an older firmware from 2014 if i remember)
Last night i was tired, wanted to update to a newer version, read quickly in forums and arrived here:
ftp://ftp.dd-wrt.com/betas/2018/07-16-2018-r36330/tplink_tl-wr941ndv3/
I flashed the firmware via the dd-wrt interface. It ended ok, rebooted... and now the router is in a reboot loop.
Sys never came on.
Al lights turn on. Power remains. eth1 flashes a few seconds. And then again, al lights on. Endlessly.
Configuring 192.168.1.2 and pinging .1 gave me nothing.
What can i do?
Thanks!
Its probably the same hardware as an 841, try the 192.168.0.66 tftp method that works great for those. I've resurrected wr841nv9 and wr841nv11 models multiple times when they went into a bootloop from either a bad upgrade with openwrt or ddwrt. Just get a copy of the OEM firmware file and rename it to whatever tftp logs that the machine tries to retrieve when you try it the first time.
Hi! Thanks for your answer!
I tried that, but is a no go
Tried setting the computer local ip to .0.66 and .1.1, etc, but the interface goes up and down in 2 seconds and the tftp server doesn't get any request.
Tried with 2 notebooks and a desktop pc (win10, win7) and same result.
I even tried to scan with wireshark any arp request and nothing... there is zero traffic from the router.
I don't know how the upgrade to a newer dd-wrt firmware bricked this router like that. But so far, nothing
You didn't mention that you held in any button while powering it up, did you try holding in one of the rear function buttons while turning on the power? It will not try tftp unless you push in one of the rear buttons, not sure which one I do but try one at a time. WR841 has 2 buttons, one for wifi being on/off and the other for WPS/reset. I think it was the WPS one, since that makes sense the reset would be the button to trigger it.
I tried to flash my WR941ND ver. 3.6 with the latest DD-WRT firmware - upgrade process finished successfully, but after that I got stuck in infinite bootloop as you can see at the short clip attached below
I bricked 2 of these, a v3.5 and a v3.6. Managed to recover one via serial connection (installed Gargoyle 1.10), and lost the other in the process of shorting TX to the pins below it when I accidentally lifted a trace.
Then I tried to update a WR1043ND v1, and bricked it too. Soldered header pins, connected to it via serial, and flashed Gargoyle.
Firmware 2018-10-04-2018-r37139-tplink_tl-wr1043nd bricks the router.
What's going wrong?
Log from UART:
[ 1.080000] No filesystem could mount root, tried: squashfs
[ 1.090000] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(31,2)
I`d recover it from tftpboot, but I would want to setup dd-wrt instead of factory. I tried any other firmwares but no luck.
