I downloaded the factory images for my TP-Link 1043N V5 and tried to use the sysupgrade command with it. When I got errors, I did this -
# cd /tmp
/tmp # mtd -r openwrt-18.06.1-ar71xx-generic-tl-wr1043n-v5-squashfs-factory.bin firmware
Right now, I'm only getting a light on the power LED and nothing else. If I reboot the router, the power LED blinks only once and then stays on without blinking. I'm not seeing any other light on any other LED.
I wasn't able to enter the failsafe mode and I tried using the reset button but that isn't helping either. Pressing the reset button at boot just switches on the last LED (with two arrows on either direction) for a few seconds and then the power LED is the only LED that is on.
/tftpboot is owned by the user with 777 permissions and I've kept the file in it with the original name as downloaded. However, after running that command, I'm unable to see a process with that name using htop or ps command.
I restarted my router while pressing the reset button using a pen and the router just started with a single blink in power and staying on and few seconds of the last LED being on. I see nothing else.
I know that I have things working on my desktop. The tftp server has started successfully. I'm able to use the tftp client on my desktop to get the firmware that I'm trying to serve. I've assigned the static IP of the host as 192.168.0.66. The router is connected to the PC via LAN and not WAN.
EDIT: I've also disabled the iptables.service if that's of any concern.
Sorry, but that didn't work either. I'm getting the same reaction no matter what I do. The power LED stays on without blinking (except once) and no other LED blinks or switches on. The last LED lights up for about 3-5 seconds when I press the reset button at the start but that's it.
Then reflash OpenWrt ("sysupgrade" not "factory") on it if you can reach failsafe.
For future reference, openwrt-xxx-factory.bin files are used only for flashing from stock firmware to OpenWrt, not reverting back to stock firmware or upgrading. So if you are able to get in to failsafe mode and get OpenWrt working on it again and wish to revert back to stock firmware, you will want to download the stock firmware off TP-Link's website for your TL-WR1043N V5. SCP that firmware to the /tmp directory of your router. Then SSH in to the router and run the following commands:
dd if=<stock_firmware_image> of=tplink.bin skip=257 bs=512
(In order to flash the TL-WR1043N/ND series stock firmware we need to strip the uboot image off it when flashing it under OpenWrt)
mtd -r write tplink.bin firmware
(Write the stripped firmware)
Go through the site tmomas posted and get a clue what is possible.
First disconnect all network adapters/cables from your system.
Install tcpdump. On debianlike distribution with apt-get update && apt-get install tcpdump
then go on with - on old debain
change $INTERFACE to your interface
ifconfig $INTERFACE down
ifconfig $INTERFACE up
ifconfig $INTERFACE 192.168.0.66
on new debain
ip link set $INTERFACE up
ip addr add 192.168.0.66/24 dev $INTERFACE
dont mess with netmask just give that a try:
start tcpdump tcpdump -i $INTERFACE
start your router and press the reset button keep it pressed for 15 seconds and
read the output, you'll hopefully see the ipadress of your router asking for tftp then stop tcpdump with ctrl+c .. try to start the server with verbose output
read about it in tftpd --help
i never use original firmware from tplink to debrick i always use the openwrt-***-factory.bin it should work if your router is compatible, so you dont have to mess around with dd.
Does the LAN LED of your router switch on when you insert the rj45-cable? Does ifconfig gives you a Scope:Link ?
Or try out ip link to see if the network card has a physical connection to your router.
Your router will restart if he could'nt find the tftpd server tcpdump is usefull to see the timespan you have. And if the router actually boots to recovery.
@lucize What should I watch out for? I guess there would be a timing issue if it were possible for the router to go to failsafe mode but that isn't possible right now because the power LED doesn't blink. It just stays on as soon. If I press a reset button before powering on the router and keep pressing the reset button, the last LED lights up (without blinking) for maybe 5 seconds and then that goes away as well along with a single blink on the power LED. This happens even if I press the reset button after a second of starting the router.
@mj5030 Using the --verbose flag gave me nothing different.
@mj5030 Like I said before, I don't think that going into the failsafe mode is possible because the power LED doesn't blink ... at all.
@eliasmagnus Thanks for the help. However, I didn't see any output in either Wireshark or tcpdump. I tried connecting my Ethernet cable to both the LAN and WAN port and used both 192.168.0.66 and 192.168.1.66. No output. Nothing.
